Problems solved by technology

The disadvantage of this method is that the three devices are not related to each other, resulting in waste of resources and space. At the same time, since the three devices do not have communication functions, they cannot communicate with the control computer through the communication bus.

Abstract

Being in use for breaker, the multifunctional trip includes power supply module, sampling module, CPU, communication module as well as one or more modules selected from following functional modules: shunted exciter, switching in, and under voltage. Technical scheme of the invention combines three general functions of trip for breaker: shunted exciter, switching in, and under voltage tripping, and controls the functions by CPU so that control is simple and resources are saved. Moreover, communication module is added to the disclosed multifunctional trip. Whole physical volume is smaller.

Description

technical field [0001] The invention relates to a tripper installed in a circuit breaker, more specifically, a multifunctional tripper with a communication function and combining the functions of shunt excitation, closing and undervoltage tripping. Background technique [0002] Shunt excitation, closing and undervoltage tripping are three commonly used functions in a release for a circuit breaker. In the prior art, the above three functions are separate devices, each with its own control device. The disadvantage of this method is that the three devices are not related to each other, resulting in waste of resources and space. At the same time, since the three devices do not have communication functions, they cannot communicate with the control computer through the communication bus. Contents of the invention [0003] The object of the present invention is a multifunctional release with communication function and combined with the functions of shunt excitation, closing and u...
