Abstract

The invention discloses a simulated test device and method for opening/closing of a circuit breaker, relates to the field of electrical technology, and aims at solving the problems that a breaker operation state determination method in the prior art cannot be used to determine the practical operation state of the circuit breaker accurately or predict the residual life of the circuit breaker. The simulated test device comprises an opening/closing simulation unit for simulating the operation state of the circuit breaker, a trigger unit triggers the opening/closing simulation unit to switching among different states according to a triggering voltage signal, a coil voltage control unit providing the triggering voltage signal, and a data collection unit which collects simulation state, current and triggering voltage signals, and stores and analyzes the signals to form a database. The simulated test device for opening/closing of the circuit breaker is used to simulate operation of the circuit breaker.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a circuit breaker opening and closing action simulation test device and a test method. Background technique [0002] The circuit breaker, also known as the high-voltage switch, has the function of cutting off or closing the no-load current and load current in the high-voltage circuit. The circuit breaker is widely used in the power system with its perfect arc extinguishing structure and sufficient current breaking capacity, and has a high impact on the power supply. The system plays the role of bearing, control and protection; therefore, it is very important to monitor the operating status of the circuit breaker in order to detect, diagnose and resolve various circuit breaker faults in time, which is of great significance to ensure the safe and stable operation of the power system. [0003] Through research, it is found that the current characteristics corresponding to the op...
