Background

Circuit breakers are devices in the electrical network for protecting the electrical network and the electrical utilities, and with the development of technology, especially the development of electronic technology, more and more functions are added to circuit breakers. On the one hand, because very much function is added into the circuit breaker, lead to the setting of circuit breaker function, use to become more complicated, from promoting user experience aspect consideration, hope to keep the simple and convenient operation of function commonly used. On the other hand, because the functions of the circuit breaker are richer and more comprehensive, such as self-carried current, voltage, power, electric energy, busbar temperature measurement and the like, the circuit breaker can completely replace an ammeter, a voltmeter and a power meter on a current power distribution cabinet and a current distribution box, and even can be a multifunctional meter. However, on the site of the power distribution cabinet and the power distribution box, the basic information needs to be displayed.

In the prior art, there are two main types of switch boards:

the economical power distribution cabinet is provided with a traditional pointer type current and voltmeter, cannot display complete three-phase current and three-phase voltage, and only displays one-phase voltage and three-phase current, even only displays one-phase voltage and one-phase current. The circuit breaker only has a manual opening and closing function, and the manual opening and closing may increase the danger of an operator due to the fact that the circuit breaker operates in a power grid.

Various physical interfaces and communication protocols make the development of the circuit breaker very inconvenient. The communication function is not the work of the circuit breaker, but various communication interfaces occupy part of the internal space of the circuit breaker at present, so that the mould is more complex, and the development cost is increased. And once the mould is opened, the functions need to be added and changed at the later stage, so that the cost is very high, and some of the moulds can not be modified. The integration of various communication interfaces and communication protocols consumes a large amount of software and hardware resources, so that the cost of the software and the hardware is greatly increased.
