REX010 HESG324426R1地面故障保护装置 英文资料：

Brand and model: ABB (Switzerland) REX010, material number HESG324426R1, is an injection type protection unit for generator stator grounding faults.

Core positioning: Dedicated to 100% grounding fault protection of stator in medium and high voltage generators, it needs to be used in conjunction with REX011 injection transformer and REG216/316 relay.

Working principle: Using injection detection, low-frequency signals are injected into the stator circuit to accurately detect all winding grounding faults, including the neutral point.

Power supply specifications: The auxiliary power supply is DC 36-312VDC, compatible with the power station battery system, and does not require additional AC power supply.

Voltage adaptation: The maximum monitoring voltage on the primary side can reach 3200VDC, covering mainstream medium and high voltage generator systems.

Frequency range: Suitable for 50/60Hz power frequency systems and compatible with global grid frequency standards.

Protection range: Achieve 100% stator winding grounding fault protection, including neutral point area, without protection blind spots.

Double point detection: It can identify two independent grounding points within the protected area, improving the ability to detect faults under complex working conditions.

Self check function: continuously monitor the injected voltage, signal amplitude/frequency, and grounding system status, and automatically alarm for abnormalities.

System compatibility: seamlessly cooperate with ABB REG216 and REG316 protective relays to form a complete stator/rotor grounding protection scheme.

Installation form: Modular design, suitable for embedded installation in switchgear, compact structure.

Environmental adaptation: working temperature -20 ℃~+55 ℃, storage temperature -40 ℃~+85 ℃, meeting the harsh environment of power plants.

Protection level: IP65 shell protection, dustproof and waterproof, suitable for industrial and power plant sites.

Weight and dimensions: approximately 7.35kg, dimensions of approximately 25.4 × 20.3 × 1.3cm, convenient for cabinet layout.

Application scenarios: High voltage generator systems such as thermal/hydraulic/nuclear power plants, industrial self owned power plants, and ship power plants.

In summary, REX010 HESG324426R1 is an injection type ground fault protection core unit designed by ABB specifically for medium and high voltage generators. With 100% full winding protection, dual point detection, wide voltage DC power supply, and high protection as its core advantages, it is a key equipment to ensure the safe operation of large generators.
