How much is the relay protection tester?

Scope of Application

HCM-BThe circuit breaker simulator is primarily used for the overall testing of relay protection devices. This device can simulate the tripping of circuit breakers during the overall testing of relay protection devices./Closing the switch can reduce the number of switching operations, thereby extending the lifespan of the circuit breaker.,Shorten debugging time, enhance test efficiency, and avoid the inconvenience caused by circuit breakers frequently opening and closing during a group test.

HCM-BSimulated circuit breakers can be paired with our company's producedHC、JJCSeries Relay Protection Testers Conduct Uninterrupted Verification of Protection Devices, Enhancing Power Supply Reliability.

The circuit breaker simulator includes two test programs: dual-coil simulation and high/low voltage simulation. Under the startup interface, pressCircuit Breaker Trip CurrentI"And 'trip current'II'Press the button to enter the corresponding program. The difference between the two test programs lies in the trip circuit.'ICircuit breaker tripIIThe interrelation with the closing circuit.

Circuit breaker tripINo Chinese content provided.IIThe system features two completely independent circuit breakers, with the common reference points for both breaker circuits isolated.

In the high and low voltage simulation test program, the trip circuitIThe and switch circuit achieves mutual exclusion for connection and disconnection, i.e., the circuit breaker circuit.IWhen a tripping current occurs, the simulation device switches from the closed position to the tripping position, i.e., the tripping circuit is opened, and the closing circuit is connected, allowing the closing signal to be received. Tripping circuitIIThe difference between the and-hop circuit and the trip circuit.ICircuit breaker tripIIDuring a circuit breaker trip current, Circuit breaker tripIIThe corresponding phase transitions to the trip state, simultaneously illuminating the indicator light for that phase. The output contact for that phase changes to a closed state and the indicator light turns on, which does not affect the closing circuit status. When current is present in the closing circuit, the simulation device transitions from the trip state to the closing state, meaning the closing circuit is opened and the indicator light illuminates, while the trip circuit...INo Chinese content provided.IIThe corresponding phase circuit is connected, simultaneously the corresponding phase's contactor in the output relay becomes closed and the indicator light illuminates.

In the double-coil simulation test program, the circuit breaker operationIOr circuit breaker tripIIAt any phase, when the trip current occurs, the simulation device switches from the closed state to the trip state, i.e., the trip circuit.INo Chinese content provided.IIThe middle phase trip circuit is disconnected, and the closing circuit of this phase is connected, allowing it to accept the closing signal while the trip circuit...INo Chinese content provided.IIThe indicator light of Zhongtong Xiang turns on, and the corresponding output contact's make contact becomes closed and the indicator light illuminates. When there is current in the closing circuit, the simulation device transitions from the tripping state to the closing state, i.e., the closing circuit is disconnected and the indicator light turns on, and the tripping circuit...INo Chinese content provided.IIThe corresponding phase circuit is connected, simultaneously causing the corresponding phase's contact point in the output to close and the indicator light to illuminate.
