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 operations, thereby extending the lifespan of the circuit breaker.,Reduce debugging time, enhance test work efficiency, and avoid the inconvenience caused by the frequent opening and closing of circuit breakers during a full set of tests.

HCM-BSimulated circuit breakers can be paired with our company's producedHC、JJCSeries Relay Protection Test Instruments, perform uninterrupted verification of protective 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, press"Trip Current"I'and 'trip current'II'Press the button to enter the corresponding program. The difference between the two test programs lies in the circuit breaker trip circuit.ICircuit breaker tripIIThe relationship with the closing circuit.

Trip circuitINo Chinese content provided.IIThe circuit breakers feature two completely independent trip current loops, with the common reference point for both trip loops being isolated.

In the high and low voltage simulation test program, the circuit breaker tripIThe and gate circuit achieves mutual exclusion in connection and disconnection, i.e., the trip circuit.IDuring a trip current, the simulation device switches from the closed state to the tripped state, i.e., the trip circuit is opened, and the close circuit is connected, allowing the close signal to be received. Trip circuitIIThe difference between the and-coil circuit and the trip circuitICircuit breaker tripIIThere is a trip current., Circuit breaker tripIIThe corresponding phase switches to trip status, 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...IAnd circuit breaker tripIIThe corresponding circuit of the phase is connected, simultaneously, the corresponding make contact in the output terminal of the phase becomes closed and the indicator light illuminates.

In the dual-coil simulation test program, the circuit breaker functionIOr circuit breaker tripIIIn the event of a tripping current in any phase, the simulation device switches from the closed circuit state to the tripping state, i.e., the tripping circuit.INo Chinese content provided.IIThe phase of the circuit breaker has tripped, and the closing circuit for this phase is now connected, ready to receive a closing signal.INo Chinese content provided.IIThe indicator light for Phase Zhong Tong turns on, and the corresponding output contact's make contact changes to a closed state, along with the indicator light.
