Problems solved by technology

[0003] Most of the 10KV intervals of the 35KV substation of the power supply company are located outdoors. According to the provisions of the electric safety work regulations, when the staff overhauls the circuit breaker, they only need to install grounding wires on both sides of the circuit breaker. However, due to the 10KV circuit breaker The horizontal distance between the transformer and the 10KV bus down-lead is about 1.3 meters, so that when the maintenance personnel

Abstract

The invention is applied to a breaker maintenance system, belongs to the technical field of a breaker maintenance safety protection apparatus, and discloses an outdoor 10kV breaker maintenance safety protection apparatus, for solving the technical problem of providing a breaker maintenance safety protection apparatus which has the advantages of high insulation reliability and high portability. The technical scheme employed by the invention is as follows: the outdoor 10kV breaker maintenance safety protection apparatus comprises a first protector, the first protector comprises two crossed fixation beams, the two fixation beams are hinged together through a first pin at a cross section, the first protector further comprises a square grid network, and the four corners of the square grid network are movably connected with the two ends of each fixation beam through four connection devices, such that the two fixation beams can rotate about the first pin and are superposed together.

Description

Technical field [0001] The outdoor 10KV circuit breaker inspection and repair safety protection device of the present invention belongs to the technical field of circuit breaker inspection and repair safety protection devices. Background technique [0002] Circuit breaker refers to a current switch device that can close, carry and break under normal and abnormal circuit conditions. The circuit breaker can not only be used to distribute electric energy and start asynchronous motors infrequently, but also to protect power lines and motors. They can automatically cut off the circuit when serious overload or short circuit and undervoltage faults occur, and their function is equivalent to a combination of a fuse switch and an overheating relay. [0003] Most of the 10KV intervals of the 35KV substations of the power supply company are located outdoors. According to the electrical safety work regulations, the staff only need to install ground wires on both sides of the circuit breaker wh...
