Product Details

1. Product Overview

The ABB HIES308461R0012 is a Water-Cooled Resistor manufactured by ABB Drives, with a resistance value of 2.5Ω, adopting forced water cooling method, specifically designed for ABB ACS6000 and ACS8000 series medium voltage drive systems. It is used for braking energy dissipation, DC bus discharge, power electronics circuit protection, and pre-charge circuit applications, serving as an important energy-consuming and protection component in medium voltage high-power drive systems.

In medium voltage high-power drive systems, when the motor is in generating mode (such as crane lowering, rolling mill deceleration, test stand back-driving, etc.), the motor converts mechanical energy into electrical energy and feeds it back to the drive DC bus, causing the DC bus voltage to rise. If this excess energy is not dissipated in time, the excessive DC bus voltage will damage the drive's power semiconductor devices (IGCT, IGBT, etc.). The function of the water-cooled braking resistor is to connect to the DC bus through the braking chopper when the DC bus voltage exceeds the set threshold, dissipating the excess electrical energy in the form of heat, which is then carried away by the cooling water circulation, maintaining the DC bus voltage within a safe range and protecting the drive and motor system.

The HIES308461R0012 adopts forced water cooling design. The heat generated by the resistance element is conducted to the cooling water through close contact with the water-cooled heat sink, and carried away by the external cooling water circulation system. Compared with traditional air-cooled resistors, water cooling has significant advantages such as high heat dissipation efficiency, small size, no fan noise, suitable for enclosed space installation, no dust and oil inhalation, etc. It is particularly suitable for applications with limited space inside medium voltage drive cabinets, dusty environments, and high noise control requirements. The water cooling method can achieve high-power energy dissipation in a compact volume, meeting the high power density requirements of braking resistors in medium voltage high-power drive systems.

This resistor adopts low inductance design (reference parameter < 1µH, specific subject to official data sheet). The parasitic inductance of the resistance circuit is extremely small, effectively suppressing voltage spikes (induced voltage caused by di/dt) generated when the braking chopper turns off, protecting power semiconductor devices in the braking chopper and DC bus circuit from overvoltage impact. Low inductance design is particularly important for medium voltage high-power drive systems because the system operating voltage is high and the current change rate is large, and voltage spikes caused by parasitic inductance can reach thousands of volts, sufficient to damage power devices.

In terms of overload capability, water-cooled resistors usually have strong short-time overload capability (reference parameter 300% rated power for 10 seconds, specific subject to official data sheet), capable of absorbing short-time large energy surges generated during braking. In practical applications, braking conditions are usually short-term (such as crane lowering process, rolling mill deceleration process), and the braking resistor needs to absorb a large amount of energy in a short time, then dissipate the heat through cooling water during non-braking periods. The high heat capacity and efficient heat dissipation of water-cooled resistors enable them to handle this periodic short-time large energy surge.

As a matching spare part for ABB medium voltage drive systems, the HIES308461R0012 works with ABB braking choppers, cooling water circulation systems, temperature sensors, etc., to form a complete braking energy dissipation circuit. The resistor is usually equipped with a temperature monitoring device (such as thermistor or thermocouple) to real-time monitor the resistance element temperature. When the temperature exceeds the set threshold, it sends an over-temperature alarm signal to the drive control system, and if necessary triggers protection actions (such as reducing braking power or blocking the braking chopper) to prevent the resistor from being damaged due to overheating. The cooling water circuit is usually equipped with flow switches and temperature sensors to monitor cooling water flow and inlet/outlet water temperature, ensuring normal operation of the water cooling system.

This water-cooled resistor is widely used in the following medium voltage high-power drive applications: metallurgical rolling mill main and auxiliary drives (rapid acceleration/deceleration, reversing mill), cranes and hoists (load lowering braking), mine hoists and winches, test stands and dynamometer systems (back-driving generating conditions), marine electric propulsion systems (rapid deceleration and reversing), large centrifuges and separators (rapid shutdown), large fans and pumps (rapid deceleration energy saving), oil and gas pipeline compressors (energy recovery braking), etc. In these applications, the water-cooled braking resistor ensures safe and reliable operation of the drive system under various conditions, effectively absorbing braking energy and protecting power electronic devices.

Note: This product HIES308461R0012 is a water-cooled resistor matching ABB medium voltage drives. In public information, various suppliers have different descriptions of technical parameters (rated power, dimensions, weight, protection degree, material, cooling water flow, operating temperature, etc.).

  2. Small size, high power density: Due to high heat dissipation efficiency, water-cooled resistors are much smaller than air-cooled resistors of the same power, suitable for installation in limited space inside medium voltage drive cabinets
  3. No fan noise: Water-cooled resistors have no fans themselves, low operating noise, suitable for applications with high noise control requirements (such as test stands, laboratories, equipment near office buildings)
  4. No dust and oil inhalation: Air-cooled resistors inhale ambient air through fans for cooling, which may draw dust, oil, metal chips, etc. into the resistor interior, potentially causing insulation degradation and short circuits; water-cooled resistors are enclosed cooling with no such problem, suitable for dusty and oily industrial environments
  5. Suitable for enclosed space installation: Water-cooled resistors do not require 大量 ambient air circulation, can be installed in enclosed control cabinets or drive cabinets
  6. High cooling water quality requirements: Water cooling systems have certain requirements for cooling water quality (conductivity, pH, oxygen content, hardness, etc.), requiring regular maintenance and cooling water replacement to prevent scaling and corrosion in the water circuit
  7. Leakage risk: Water circuits have potential leakage points such as pipe connectors and seals, requiring regular inspection and maintenance to prevent cooling water leakage causing electrical short circuits
  8. Higher initial cost: Initial investment in water-cooled resistor + cooling water circulation system is usually higher than air-cooled resistor

Air-cooled resistor features:

  1. Simple structure, low cost: Air-cooled resistors have simple structure, no cooling water circulation system needed, low initial investment
  2. Easy maintenance: No cooling water system to maintain, low daily maintenance workload
  3. No leakage risk: No cooling water leakage problem
  4. Lower heat dissipation efficiency: Air cooling efficiency is low, large size for the same power, requires large installation space
  5. Fan noise: Cooling fans generate noise during operation
  6. Dust and oil inhalation: Fans inhale ambient air, may draw dust, oil, etc. into the resistor interior
  7. Requires good ventilation: Air-cooled resistors require good ambient ventilation conditions, not suitable for enclosed space installation

How to choose:

  1. Medium voltage high-power drive systems → Usually select water-cooled resistors, because space inside medium voltage drive cabinets is limited and power is high, water cooling has high efficiency and small size
  2. Low voltage low-power drive systems → Usually select air-cooled resistors, low cost, simple structure, easy maintenance
  3. Limited installation space → Select water-cooled resistors, small size, high power density
  4. Dusty/oily environments (such as metallurgy, mining, chemical) → Select water-cooled resistors, no dust inhalation problem
  5. High noise control requirements (such as test stands, laboratories, near office buildings) → Select water-cooled resistors, no fan noise
  6. Enclosed control cabinet installation → Select water-cooled resistors, no ambient ventilation required
  7. Limited budget, low-power applications → Select air-cooled resistors, low cost
  8. Insufficient cooling water system maintenance conditions → Select air-cooled resistors, easy maintenance

To confirm suitability for your application, please provide drive model, braking power, braking cycle, installation space, environmental conditions, cooling water conditions, etc.; Contact via email, we can assist in confirming selection.

Q3: What are the cooling water requirements for water-cooled resistors? How to maintain the water circuit?

A: The cooling water system of water-cooled resistors has certain requirements for water quality, flow, temperature, and pressure. Proper cooling water management is the key to ensuring long-term reliable operation of water-cooled resistors.

Cooling water quality requirements (reference, specific subject to ABB official technical requirements):

  1. Water type: Usually use deionized water or distilled water, or qualified cooling water (such as ethylene glycol aqueous solution with corrosion inhibitor)
  2. Conductivity: Usually required ≤ 5 µS/cm (deionized water), preventing electrochemical corrosion of water circuit
  3. pH value: Usually required 6.5 ~ 8.5, neutral or weakly alkaline, preventing acidic water from corroding metal parts
  4. Oxygen content: As low as possible, dissolved oxygen accelerates metal oxidation corrosion, closed circulation system can be used to reduce oxygen dissolution
  5. Hardness: Low hardness or zero hardness (deionized water), preventing calcium carbonate scaling
  6. Chloride/sulfate ions: Content as low as possible, preventing stainless steel pitting corrosion
  7. Suspended solids/particles: As few as possible, preventing particle wear of water circuit and channel blockage, filters must be installed
  8. Microorganisms: Control microbial growth, preventing biofilm formation affecting heat dissipation

Cooling water operating parameter requirements (reference, specific subject to ABB official data sheet):

  1. Inlet water temperature: Usually required ≤ 35°C (or ≤ 40°C), lower inlet temperature means better heat dissipation
  2. Outlet water temperature: Usually required ≤ 55°C (or ≤ 60°C), excessive outlet temperature indicates insufficient heat dissipation
  3. Cooling water flow: Determined based on resistor power and temperature rise requirements, insufficient flow leads to insufficient heat dissipation; Contact via email for specific flow requirements
  4. Cooling water pressure: Usually required 1 ~ 4 bar (or 0.5 ~ 6 bar), excessive pressure may damage seals, too low pressure means insufficient flow
  5. Pressure drop: Inlet/outlet pressure drop of water-cooled resistor is usually several kPa to tens of kPa, used to monitor whether water circuit is blocked

Water circuit maintenance key points:

  1. Regular water quality inspection: Test cooling water conductivity, pH, hardness, etc. every 3~6 months, replace cooling water when water quality exceeds standards
  2. Regular cooling water replacement: Usually replace cooling water every 6~12 months (specific period determined based on water quality test results), simultaneously clean water circuit when replacing
  3. Clean water circuit: When replacing cooling water, use special cleaning agent to clean water circuit interior, removing scale, biofilm, and corrosion products
  4. Check filters: Regularly check and clean cooling water filters (usually every 1~3 months), preventing filter blockage causing insufficient flow
  5. Check for leaks: Regularly check all connectors, valves, hoses, seals in water circuit for leaks, handle leaks promptly when found
  6. Monitor flow and temperature: Real-time monitor cooling water flow and inlet/outlet water temperature through flow switches and temperature sensors, alarm promptly when flow is insufficient or temperature is too high
  7. Venting operation: When initially filling water or after maintenance, venting operation must be performed to exhaust all air from water circuit, preventing air lock affecting heat dissipation
  8. Anti-freeze protection: In environments where ambient temperature may drop below 0°C, antifreeze (such as ethylene glycol) should be added to cooling water, or cooling water should be drained during shutdown to prevent freezing and cracking
  9. Prevent cavitation: Ensure sufficient positive pressure head at pump inlet, preventing vaporization at pump inlet causing cavitation, damaging pump and water circuit

Specific cooling water quality requirements, operating parameters, and maintenance periods are subject to ABB official technical documentation; Contact via email for confirmation. Installation and maintenance of water cooling systems should be performed by qualified professionals.
