Abstract

본 발명은 컨버터 및 인버터를 구성하는 스위칭 반도체 소자로부터 발생하는 열을 냉각시키기 위한 엘리베이터의 방열판 과열 장지장치 및 방법에 관한 것으로, 엘리베이터 운행초기 주위온도가 고온이면 보조팬을 작동시키며, 엘리베이터 운행시 방열판 불량에 의한 이상과열상태이거나 연속운행으로 인한 방열판 과열상태일 경우 방열판의 불량표시나 방열판 과열표시를 하고 고정처리하여 엘리베이터의 운행을 정지시키며, 엘리베이터연속운전으로 방열판 온도가 설정대기온도 이상이 되면 케이지 도어 오픈시간을 조절함으로써 방열판의 온도상승을 감지하여 방열판의 과열을 조기에 방지함으로써 열적 상승으로부터 스위칭 반도체 소자를 보호하고 엘리베이터의 신뢰성 저하를 방지토록 한 것이다.The present invention relates to an apparatus and method for overheating a heat sink of an elevator for cooling heat generated from a switching semiconductor element constituting a converter and an inverter, wherein the auxiliary fan is operated when an initial ambient temperature of the elevator is high, and the heat sink is operated during elevator operation. In case of overheating condition due to defect or overheating state of heatsink due to continuous operation, display of defective heatsink or overheating heatsink and stop the elevator operation by fixing and stop the elevator operation. By controlling the door opening time, it detects the temperature rise of the heat sink and prevents overheating of the heat sink early, thus protecting the switching semiconductor element from thermal rise and preventing the elevator from deteriorating reliability.
