Problems solved by technology

[0002] The residual current operated circuit breaker is a control device with CPU application technology as the core. In general, the CPU in the residual current operated circuit breaker of traditional products is not equipped with a data interface for communication, so it can only realize a single and limited monitoring function and data storage memory. Functions, so that it can realize remote monitoring, data sharing and other functions have not been effectively used, resulting in waste of resources

Abstract

The invention discloses a remote monitoring circuit breaker which comprises a residual current operated circuit breaker. An RS485 and a USB communication data interface are respectively arranged on a CPU of the residual current operated circuit breaker, remote and local communication can be achieved, data interaction can be carried out in real time, and an overcurrent protection value, a residual current operating value and protection motion time can be adjusted in time through the remote operation. The circuit breaker is used in combination with low-voltage power grid integrated automation system software, remote load management can be achieved, polling manpower can be saved, operating maintenance cost can be lowered, fault treatment time can be shortened, electricity using reliability can be improved, and the first-rate service level can be improved.

Description

technical field [0001] The invention relates to a low-voltage control electrical appliance, and more specifically relates to a remote monitoring circuit breaker. Background technique [0002] The residual current operated circuit breaker is a control device with CPU application technology as the core. In general, the CPU in the residual current operated circuit breaker of traditional products is not equipped with a data interface for communication, so it can only realize a single and limited monitoring function and data storage memory. Functions, so that it can realize remote monitoring, data sharing and other functions have not been effectively used, resulting in waste of resources. Contents of the invention [0003] The present invention provides a remote monitoring circuit breaker for a power distribution automation system below 0.4KV in order to solve the above-mentioned shortcomings in the use of the existing residual current operated circuit breaker. [0004] The pr...
