Electric mechanism of isolating switch and operating method

Abstract

The invention relates to an electric mechanism of an isolating switch and an operating method, designed to solve the technical problem of poor design of a traditional similar mechanism. The mechanism comprises a gear transmission unit, a mechanism action interlocking unit, an electric appliance control unit and an external energy output unit. The mechanism is characterized in that an electric motor, small gears, large gears, a spiral groove camshaft and an output shaft of the mechanism are in transmission connection by a certain transmission ratio; a conversion switch, the spiral groove camshaft, large synchronous wheels and small synchronous wheels are connected by synchronous belts according to a certain transmission ratio; the positions of a interlocking component, the spiral groove camshaft, the small synchronous wheels, a position switch and a position lock cam are unlocked and locked by the rotation of the spiral groove camshaft; and a circuit control board, the conversion switch, the position switch, a magnet and the electric motor are used for controlling the rotation of the whole mechanism by a relay on a circuit board. The mechanism has flexible and convenient installation modes of positive installation and hanging of the isolating switch, and meets various complicated working conditions of the isolating switch.

Description

technical field [0001] The invention relates to an isolating switch device of a high-voltage switch in a power system, and relates to an electric mechanism and an operating method of the isolating switch. Background technique [0002] As we all know, the isolating switch means that when it is in the sub-position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; short circuit) current switching devices. The isolating switch plays an important role in the entire power system. In actual use, the forms of this type of switch are relatively diverse, and there are many kinds of mechanisms used, but they are all inseparable from the principle of the linkage mechanism, and most of them use spring-driven There are many types of parts and complex transmission links, which will inevitably cause instability in the operation of such switches and affect the safety and stability of the entire power distribution s...
