An overload self-repairing circuit breaker for urban island microgrid public toilets

Abstract

The invention provides an overload self-repair reconnection breaker of an urban island microgrid public toilet. The breaker structurally comprises two lock pins, a protective shell, a sealing plate, ahandle, embedded ends, a guide plate and an overload self-repair reconnection device, wherein the two lock pins are fixedly installed at the upper end and the lower end of the protective shell respectively, the sealing plate is installed in the middle position of the front end face of the protective shell in an embedded mode, the handle and the overload self-repair reconnection device are fixedlyconnected together, and the right end of each embedded end is fixedly connected to the left end of the guide plate in an electric welding mode. According to the breaker, due to the plane constrainingforce of a linkage limiting mechanism on a reconnection back-clamping mechanism, the breaker can be fixed after being adjusted, a voltage overload can make the breaker lose working capability, and consequently the breaker is temporarily ineffective; and when the voltage returns to normal, the breaker is recovered at the same time, and in the recovery period of the breaker, a self-repair reconnection mechanism continuously acts on the reconnection back-clamping mechanism, so that a swing connecting rod tries to perform intermittent autonomous connection continuously, and accordingly an internal appliance of a public toilet with a fault can recover normal use in time.

Description

technical field [0001] The invention belongs to the field of circuit breakers, and more specifically relates to an overload self-repairing circuit breaker for urban island micro-grid public toilets. Background technique [0002] Urban public toilets that use independent power supply agencies are distributed in every corner of the city. Since they are equipped with isolated island micro-grids to supply the required power, there is no need to manage the configuration of external power supplies. When, due to the diversity of conversion sources, when multiple conversion sources supply at the same time, the output power of the grid is easily overloaded. [0003] Based on the above description, the inventors found that an existing overload self-repairing circuit breaker for urban island microgrid public toilets mainly has the following deficiencies, such as: [0004] When the island micro-grid installed on the public toilet performs energy conversion and supply, due to the divers...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides an overload self-repairing circuit breaker for urban island micro-grid public toilets to solve the problem of the existing island micro-grids loaded on public toilets due to the variety of conversion sources when performing energy conversion and supply to them. When multiple conversion sources are supplied at the same time, the output power of the power grid is easily overloaded, resulting in tripping and power failure in public toilets. Due to the scattered distribution of public toilets, it is difficult for maintenance personnel to repair them in time. Only at intervals Problems that can only be discovered and repaired during the inspection period
