Novel bypass auxiliary circuit breaker replacement device

Abstract

The invention discloses a novel bypass auxiliary circuit breaker replacement device. The device comprises a novel bypass auxiliary device body and a fixing mechanism. The two ends of the novel bypassauxiliary body are arranged at a busbar and an outgoing line side of a low-voltage switch cabinet through fixing mechanisms respectively. The fixing mechanism comprises a clamping mechanism, a threading cylinder and a locking mechanism; the threading cylinder is arranged in a hollow cavity of the clamping mechanism, the novel bypass auxiliary device body is arranged in the threading cylinder, andthe locking mechanism is arranged at the two sides of the clamping mechanism and fixes the threading cylinder to a busbar and a wire outlet side of a low-voltage switch cabinet. The problem of power failure is solved, and the power failure duration during maintenance can be reduced to zero; the novel bypass auxiliary device body is prevented from falling off of the busbar and the wire outlet sideof the low-voltage cabinet, and the risk of electric shock of an operator is prevented.

Description

technical field [0001] The invention relates to low-voltage live work, in particular to the replacement of low-voltage circuit breakers, in particular to a novel bypass-assisted circuit breaker replacement device. Background technique [0002] The low-voltage circuit breaker is responsible for connecting and breaking the load current and protecting the equipment in the complete set of combined electrical appliances. If there is an abnormality, it will affect the normal operation of the distribution line and even cause a safety accident. [0003] At present, the replacement of the circuit breaker requires a power outage. Disconnecting the upper-level main switch will cause a large loss and affect the reliability of the power supply. Replacement unit for zero low voltage circuit breakers. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a new type of bypass-assisted circuit breaker in view of the above-mentioned p...
