Relay Protection Tester Price

Scope of Application

HCM-BThe circuit breaker simulator is primarily used for the overall testing of relay protection devices. This device can simulate the operation of circuit breakers during the overall testing of relay protection units./Closing the circuit breaker can reduce the number of switching actions, thereby extending the lifespan of the circuit breaker.,Reduce debugging time, enhance testing efficiency, and avoid the inconvenience caused by circuit breakers repeatedly opening and closing during a full set of tests.

HCM-BSimulated circuit breakers can be paired with our company's manufacturedHC、JJCSeries Relay Protection Testers, performing offline verification of protective devices, enhance power supply reliability.

The circuit breaker simulator includes two test programs: dual-coil simulation and high/low voltage simulation. Under the startup interface, pressTrip CurrentI"And trip current"IIPress a button to enter the corresponding program. The difference between the two test programs lies in the trip circuit.ICircuit breaker tripIIThe relationship with the closing loop.

Trip circuitIAnd circuit breaker tripIIThe system consists of two completely independent trip circuit currents, with the common reference point for both trip circuits isolated.

In the high and low voltage simulation test program, the circuit breaker tripIThe and-coil circuit achieves mutual exclusion for connection and disconnection, i.e., the trip circuit.IUpon the occurrence of tripping current, the simulation device switches from the closed state to the tripping state, meaning the tripping circuit is disconnected and the closed circuit is connected, enabling the reception of a closing signal. Tripping circuitIIThe relationship between the and-together circuit and the trip circuit is different.IThe circuit breaker trip circuitIIIn the event of a tripping 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's status. When there is current 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 circuit of the phase is connected, simultaneously the corresponding phase's contact point in the output switch becomes closed and the indicator light illuminates.

In the dual-coil simulation test program, the tripping circuitIOr circuit breaker trippingIIAt any phase, if there is a trip current, the simulation device switches from the closed state to the trip state, i.e., the trip circuitINo Chinese content provided.IIThe middle phase circuit breaker has tripped, disconnecting the circuit. The closing circuit for this phase is now energized and capable of receiving closing signals, while the tripping circuit remains disconnected.INo content provided for translation.IIThe indicator light for phase Zhong Tong turns on, and the corresponding output contact's make contact switches to a closed state along with the indicator light. When there is current in the closing circuit, the simulation device transitions from the tripping state to the closing state, meaning the closing circuit is disconnected and the indicator light illuminates, while the tripping circuit...INo Chinese content provided.IIThe corresponding phase circuit is connected, simultaneously causing the corresponding phase's junction point in the output to close and the indicator light to illuminate.
