Abstract

The invention provides a miniature circuit breaker simulation device and a use method. The miniature circuit breaker simulation device comprises a connector, a connector joint is provided with a simulation circuit module capable of generating a test simulation signal, and the simulation circuit module comprises a closing relay, an opening relay, a closing signal relay, a closing signal indicating lamp and an opening signal indicating lamp. A closing input pin H1 of the connector is connected with a normally closed contact of the closing relay, a normally open contact of the closing relay is connected with a coil end of the closing signal relay, an opening input pin F1 of the connector is connected with a coil end of the opening relay, and a normally closed contact of the opening relay is connected with the coil end of the closing signal relay. The normally closed contact of the closing relay is connected with the opening signal indicating lamp, and the normally closed contact of the closing relay is connected with the closing signal indicating lamp. The invention provides a circuit breaker simulation device which is smaller in size and lower in cost, and the circuit breaker simulation device is small, light and popular while the function of a simulation circuit breaker is met.

Description

technical field [0001] The invention relates to the technical field of circuit breaker simulation devices, in particular to a miniature circuit breaker simulation device and a method for using the device. Background technique [0002] The circuit breaker simulation device is mainly used for the whole set of tests of relay protection devices and to replace real high-voltage circuit breakers in projects such as backup power self-injection device tests. Simulate the tripping and closing of the high-voltage circuit breaker during the whole group test to avoid adverse effects caused by repeated opening and closing of the high-voltage circuit breaker due to repeated whole group tests. Using this miniature circuit breaker simulation device for relay protection tests will not Affected by external factors, the test time of the relay protection test is shortened, and the test work efficiency is improved. [0003] Relay protection is widely used in electric power, transportation, comm...
