Portable driving device and driving method for 10kV permanent magnet operating mechanism circuit breaker

Abstract

A portable driving device of a 10kV permanent magnet operating mechanism circuit breaker is arranged in a box-type aluminum alloy shell, and keys, a liquid crystal display screen, an indicating lamp and a switch-on button with a lamp are installed on the front face of the aluminum alloy shell. An aviation plug, a manual switch and a three-core power socket are arranged at the top of the aluminum alloy shell; a core board, an aluminum electrolytic capacitor, a DC/DC boosting module, a lithium battery pack, a battery bin and an AC/DC conversion module are installed in the aluminum alloy shell. The core board is provided with a CPU, an A/D collection module, a power supply management module, a DC/DC voltage reduction module, a discharge module, an H bridge and a driving module. The inventionfurther provides a driving method of the portable driving device of the 10kV permanent magnet operating mechanism circuit breaker. The problem that a 10kV circuit breaker of a monostable permanent magnet operating mechanism can operate a switch to be switched off in a mechanical mode when a driving module cannot work, but cannot operate switching-on can be solved.

Description

technical field [0001] The invention relates to the technical field of closing operation of a monostable permanent magnet mechanism in a distribution network of a power system, in particular to a portable driving device and a driving method for a circuit breaker of a 10kV permanent magnet operating mechanism. Background technique [0002] The opening and closing operations of the switches in the 10kV circuit breaker equipment in the power system distribution network are mostly completed by spring-type operating mechanisms at this stage. Compared with the spring-type operating mechanism, the permanent magnet operating mechanism has outstanding advantages such as simple structure, fewer mechanical parts, and high speed, and has a tendency to be widely used. Permanent magnet mechanisms are divided into monostable permanent magnet mechanisms and bistable permanent magnet mechanisms. Currently, monostable permanent magnet mechanisms are more commonly used. The main components of...
