Abstract

본 발명은 교통신호제어기의 전력제어장치에 관한 것으로, 종래 교통신호제어기의 전력제어장치는 매 단계별로 출력되는 제어신호 패턴의 일시에 인가되므로 각 단계별 변화시점에서 큰 폭의 돌입 전류가 발생하게 된다.The present invention relates to a power control device of a traffic signal controller, and the power control device of the conventional traffic signal controller is applied at a time of a control signal pattern outputted at each step, so that a large inrush current is generated at each change point of the step. .

이에 따라 정격전류값보다 현저하게 큰 전류용량의 퓨즈를 선택하게 되어 동작시 자동 트립(trip)이 발생하고, 또한 전류용량을 크게 설정하면 실제 단락상황에서 전력제어소자등의 파손을 초래하는 경우가 발생하는 문제점이 있었다.As a result, a fuse having a current capacity significantly larger than the rated current value is selected, and an automatic trip occurs during operation, and setting a large current capacity may cause damage to a power control device in an actual short circuit situation. There was a problem that occurred.

본 발명은 이러한 문제점을 해결하기 위하여 각 제어단계 변화시점에서 발생하는 돌입전류를 분산시킴으로써 돌입전류의 피크치가 낮아지므로, 퓨즈를 실제 최고전류소비값에 가깝도록 낮게 설정하여 전력제어소자를 보호할 수 있도록 하는 것이다.In order to solve this problem, the peak value of the inrush current is lowered by distributing the inrush current generated at each control stage change point, so that the power control device can be protected by setting the fuse lower than the actual maximum current consumption value. To ensure that
