Automatic low-voltage circuit breaker control apparatus with remote monitoring function and application therefor

Abstract

An automatic low-voltage circuit breaker control apparatus with a remote monitoring function and an application therefor are disclosed. The apparatus comprises an analog signal collection unit, a data processing unit, a man-machine interaction unit, a tripping execution unit, a remote communication unit and a power supply, wherein a rogowski coil and a current sampling circuit are adopted to input a current signal into an analog signal conditioning circuit; a voltage sampling switching circuit inputs a voltage signal into the analog signal conditioning circuit; the analog signal conditioning circuit inputs an analog signal into an analog multi-path switch to be converted into a digital signal to be input into the data processing unit; a microcontroller in the data processing unit processes the input digital signal, and judges and / or outputs a corresponding trip signal to the tripping execution unit so as to execute a tripping action; and meanwhile, fault scenes and fault reasons are transmitted to a centralized control console through the remote communication unit. The automatic low-voltage circuit breaker control apparatus has the characteristics of accurate multi-working-condition barrier judgment, convenient circuit reconstruction and adjustment, and easy remote monitoring.

Description

technical field [0001] The invention relates to the field of low-voltage circuit safety, in particular to an automatic low-voltage circuit breaker control device with remote monitoring function and its application. Background technique [0002] During the "Twelfth Five-Year Plan" period, with the advancement of smart grid construction and the continuous development of low-voltage electrical appliance production technology, a new generation of low-voltage electrical appliances featuring intelligence, modularization, and communication will become mainstream products in the market. The first-generation products will exit the market in 2010, the second-generation products will be low-end products, and the third-generation products and some second-generation products will be mid-range products. From 2011 to 2015, the smart grid will enter the stage of comprehensive construction in seven aspects including power transmission, power transformation, power distribution, and communicat...
