Intelligent low-voltage circuit breaker controller

Abstract

The invention discloses an intelligent low-voltage circuit breaker controller. The intelligent low-voltage circuit breaker controller comprises a signal acquisition circuit, a temperature detection circuit, a microprocessor, an execution module, a clock calibration module, a keyboard and an externally-expanded memorizer circuit, wherein the signal acquisition circuit is used for acquiring a current change value and a voltage change value of a power grid and generating an acquired signal to be sent to the microprocessor; the temperature detection circuit is used for detecting the change of temperatures and sending a generated temperature changing signal to the microprocessor; the microprocessor is used for sending the received acquired signal and temperature changing signal to a display module, processing the received acquired signal and temperature changing signal and sending a generated executing signal to the execution module; the microprocessor is further used for sending the acquired signal, the temperature changing signal and the executing signal to the externally-expanded memorizer circuit; the execution module is used for carrying out switching on/off movement on a low-voltage circuit breaker switch according to the received executing signal; the clock calibration module is used for carrying out clock calibration on the microprocessor; the keyboard is used for setting the initial parameter value of the microprocessor; the externally-expanded memorizer circuit is used for wirelessly sending the signals sent by the microprocessor to a remote console to be stored simultaneously.

Description

technical field [0001] The invention relates to the technical field of low-voltage circuit breakers, in particular to a novel intelligent low-voltage circuit breaker controller. Background technique [0002] The low-voltage circuit breaker is an important component that plays the role of segment control and protection in the low-voltage power distribution system. At present, foreign low-voltage circuit breakers are developing in the direction of high performance, miniaturization, intelligence and modularization, and are connected with the field bus system to realize networking. Some domestic manufacturers have also developed international standard low-voltage circuit breaker controllers, but their main disadvantage is that they use less large-scale integrated devices, so they are large in size and easy to interfere. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the invention provides an intelligent low-voltage circuit breaker c...
