Intelligent controller for universal breaker and control method thereof

Abstract

The invention relates to an intelligent controller of a universal circuit breaker, and a control method thereof; the intelligent controller comprises a circuit breaker alarm signal normal-open node, a single chip computer, a RS485 level conversion interface circuit, two optical couplers, a direct current electromagnetic coil, an iron core of the direct current electromagnetic coil which is also used as the reset button of the circuit breaker, and a signal output terminal; the port of a general asynchronous receiving and emitting device inside the single chip computer is connected with the port of the RS485 level conversion interface circuit; and the output terminals A and B of the RS485 circuit are connected with the signal output terminal, thus being accessed into the communication bus of the RS485 level specification. The control method controls the circuit by the way that program setting control individually and by the control instructions emitted by a central control computer through a communication network so as to lead the controller to carry out the resetting action, thus greatly facilitating the user to lead the controller to automatically recover by the prearranged requirement or emit the recovery action by the communication network so that the recovery is carried out, when the user can not reach the equipment as the user is far away from the equipment.

Description

technical field [0001] The invention belongs to an electric switch, in particular to an intelligent controller of a universal circuit breaker and a control method thereof. Background technique [0002] The known universal circuit breaker is used as a main switch in the power distribution circuit, and it is generally installed near the power transformer. After the parameter fault protection action of this kind of switch occurs on the line, it is necessary to manually reset the circuit breaker controller at the circuit breaker site. In some cases, when the circuit breaker is far away from the central control room or cannot arrive at the site in time for other reasons, the closed circuit of the circuit breaker cannot be reset in time, which often brings great difficulties to the user. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention provides an intelligent controller and a control method of a universal...
