Problems solved by technology
The maintenance of the intelligent circuit breaker is not considered. The intelligent part is an auxiliary link of the power system, which is also a relatively weak link, and it is prone to failure factors such as poor communication.
When there is a problem with the smart part, there is no way to replace it online
Especially installed in a low-voltage power distribution drawer cabinet, when the intelligent part fails, the entire circuit or even the entire system must be powered off for maintenance
It will lead to heavy maintenance workload, losses caused by power outages, and negative social impacts.

The invention discloses an intelligent circuit breaker with mechanical locking and fixing type online replacement. The intelligent circuit breaker comprises a circuit breaker body, extended insulating shells arranged at the two ends of the circuit breaker body and wrapping part of the surface of the circuit breaker body, insulating screws fixed at the two ends of the circuit breaker body through the extended insulating shells, and a mechanical locking mechanism provided with a separation blade and a sliding mechanism for driving the separation blade to be opened and closed. The mechanical locking of the circuit breaker not only can ensure that the switch can be operated under the condition of opening, but also can play a role in fixing the circuit breaker without screw connection;` the intelligent part can be replaced on line, on-line plugging is realized from the front side, the circuit breaker does not need to be dismounted, and power failure is not needed; the periphery of the circuit breaker does not need complex structural design, production efficiency is improved, and cost is reduced.
Description
technical field [0001] The invention relates to the technical field of circuit breakers, in particular to an intelligent circuit breaker with mechanical locking and fixed on-line replacement. Background technique [0002] The existing smart circuit breaker adds data such as transformers and temperature collection on the basis of traditional circuit breakers, and analyzes various electric energy data in real time. The aspect of intelligence is constantly improving, but the implementation method and peripheral structure basically remain unchanged. The maintenance of the intelligent circuit breaker is not considered. The intelligent part is an auxiliary link of the power system, and it is also a relatively weak link, which is prone to failure factors such as poor communication. When there is a problem with the smart part, there is no way to replace it online. Especially when it is installed in a low-voltage power distribution drawer cabinet, when the intelligent part fails, t...
