Circuit breaker digital simulation device and method

Abstract

The invention discloses a circuit breaker digital simulation device and method. The device comprises an operation module which generates an operation opening signal, an operation closing signal, an energy storage signal, a mechanism failure signal, a medium fault signal, and a pressing signal; a mechanism module which is used for determining the mechanism sub-operating state, the mechanism combined operating state, and the mechanism fault state according to the operation opening signal, the operation closing signal, the energy storage signal, the mechanism failure signal, and the contact state; a contact module which is used for determining the contact state according to the mechanism sub-operating state and the mechanism combined operating state; a medium module which is used for determining the medium state based on the medium failure signal and the pressing signal, the mechanism sub-operating state and the mechanism combined operating state; and a circuit breaker module which is used for determining the circuit breaker state according to the mechanism failure state, the contact state and the medium state. The working process of the circuit breaker is simply and accurately described in real time in the simulation training, and the problems that a traditional simulation result is easy to dissipate, and the real-time performance is difficult to meet the requirements are solved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment simulation, in particular to a circuit breaker digital simulation device and method. Background technique [0002] High-voltage circuit breakers are important protection equipment for power systems, and are widely used in high-voltage systems with voltage levels of 110kV and above. Circuit breaker operation and fault handling are the basic skills that must be mastered by the on-site operation staff. Simulating the operation process of the circuit breaker and simulating various phenomena of typical faults, and simulating the whole process of the opening and closing of the circuit breaker can effectively improve the staff's ability. operational skills. [0003] The opening and closing process of the circuit breaker is completed by the operating mechanism, the arc extinguishing chamber and the contacts. When the opening and closing operation is required, the operator controls the energy...
