Low-temperature-resistant micro circuit breaker reclosing apparatus and use method therefor

Abstract

The invention discloses a low-temperature-resistant micro circuit breaker reclosing apparatus and a use method therefor, and relates to the field of a reclosing apparatus; the low-temperature-resistant micro circuit breaker reclosing apparatus solves the problem that the existing reclosing apparatus cannot work at low temperature, and can be used in outdoor environments at the temperature below minus 30 DEG C, so that the applicable scope of the reclosing apparatus is enlarged, and the reclosing apparatus has market potential. The low-temperature-resistant micro circuit breaker reclosing apparatus adopts the match of a planet cycloid mechanism groove rod and a planet cycloid pin, and the reclosing apparatus has the unique brake-separating position and unique break-reclosing position, the shortcoming that the existing reclosing apparatus judges by fully relying on sensors is solved, and the reclosing apparatus is higher in reliability. The technical key point is as follows: the low-temperature-resistant micro circuit breaker reclosing apparatus comprises a housing, a planet cycloid mechanism spanner, a planet cycloid mechanism groove rod, a planet cycloid pin, a gear module, a motor-driven gear, a motor, a detector, an external power supply socket, a bus, a signal terminal, a work indicating lamp, a reclosing failure indicating lamp and a clamping pin. The low-temperature-resistant micro circuit breaker reclosing apparatus is mainly used for reclosing of the micro circuit breakers, micro leakage protectors and other electric appliances.

Description

technical field [0001] The invention relates to the field of circuit breaker reclosing devices, in particular to a low temperature resistant miniature circuit breaker reclosing device and a use method thereof. Background technique [0002] Micro Circuit Breaker (Micro Circuit Breaker) refers to a switching device that can close, carry and break current under normal circuit conditions. It can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. When they occur It can automatically cut off the circuit in case of serious overload or short circuit and undervoltage faults. Its function is equivalent to the combination of fuse switch and overheating and underheating relay. The circuit breaker reclosing device is a motor operating mechanism with the same shape and size as the miniature circuit breaker. It is composed of a motor, a speed reduction gear set, and a control circuit, which can drive the circuit breaker to clo...
