Remote control method of circuit breaker and system applying method

Abstract

The invention relates to a remote control method of a circuit breaker and a system applying the method. The method comprises the following steps of: acquiring the state of the circuit breaker and transmitting the state to a control terminal and a server by a controller; transmitting a control instruction of the circuit breaker by the control terminal through the operator; forwarding and transmitting the control instruction to the controller through the server; and controlling the circuit breaker to correspondingly operate by the controller. The system at least comprises the control terminal and the controller which are in communication connection; the controller comprises a power supply module, a communication module, a control module, a switching value acquisition module and a relay control module. The invention has the characteristics of intellectualization, remote, networking and real-time properties, can realize the remote closing and breaking of the miniature circuit breaker, shorten the fault time due to the problem of the circuit breaker, and reduce the loss to maximum extent, thereby being more practical.

Description

technical field [0001] The invention relates to an operating system of a circuit breaker, in particular to a remote control method of a circuit breaker and a system applying the method. Background technique [0002] The miniature circuit breaker is also called automatic air switch, or air switch for short. It was born in 1923. The miniature circuit breaker invented by ABB already has the basic components of the current miniature circuit breaker, such as protection system, electrical contact system and switching mechanism. This invention was patented in Germany in 1924. In 1968, miniature circuit breakers developed a rail-mounted 68MM modular circuit breaker, and subsequently, the modular dimensions and rail specifications were adopted by the International Organization for Standardization. At the end of the 20th century, due to the development and popularization of miniaturized computers, intelligent circuit breakers came out. [0003] With the improvement of standardizatio...

AI Technical Summary

Problems solved by technology

According to the field usage, the miniature circuit breaker will be disconnected due to lightning strike, transient impact, short circuit and other reasons. Since the existing circuit breaker needs manual operation and cannot restore power supply in time, it is easy to cause interruption of signal equipment and even cause outage of railway

[0007] It can be seen that the above-mentioned existing circuit breaker control method and system obviously still have inconvenience and defects in composition, method and use, and need to be further improved urgently.
