Over-current intelligent comprehensive protection device

Abstract

The invention discloses an over-current intelligent comprehensive protection device which comprises an outer box, a front plate is fixedly installed at the front end of the outer box, a displayer is arranged on the front side of the front plate, and a clearing key, a reading key and a browsing key are arranged on the front side of the front plate. A tripping indicating lamp, an alarm indicating lamp, a fault indicating lamp, an auxiliary power indicating lamp and a programmable indicating lamp are fixedly installed on the side of the front end face of the front plate. According to the intelligent comprehensive overcurrent protection device, through mutual cooperation of the outer box, the inner box, the first heat dissipation holes and the second heat dissipation holes, heat dissipation can be quickly performed on the interior of the overcurrent protection device, the overcurrent protection device is effectively prevented from being damaged due to too high temperature, a filter screen can effectively prevent dust from entering the interior of the inner box, and the service life of the overcurrent protection device is prolonged. Meanwhile, the filter plate and the outer box can be quickly disassembled and assembled, the inner box can be directly drawn out from the interior of the outer box, a sliding rail is guided through a third sliding groove, it is ensured that the inner box slides stably, workers can overhaul the inner box conveniently, the overall size is small, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of power electronic equipment, in particular to an overcurrent intelligent comprehensive protection device. Background technique [0002] With the development of power electronic technology, how to effectively, reliably and accurately protect equipment during operation has become an increasingly important issue. For high-power power electronic equipment, protection measures are required to be issued immediately when a fault occurs. In the process of eliminating faults, it is often necessary to use overcurrent intelligent comprehensive protection devices. [0003] However, most of the existing over-current intelligent comprehensive protection devices cannot conduct rapid heat dissipation, and there are often problems that the over-current intelligent comprehensive protection device is damaged due to excessive temperature, and most of the existing over-current intelligent comprehensive protection devices canno...
