摘 要:半導體脫扣器實質是低壓斷路器的一個組成部分,其主要作用是對低壓線路的常見故障進行保護,如過載、欠電壓和短路保護。半導體脫扣器是在熱-電磁式脫扣器的基礎上,隨著半導體元件的發展而形成的一種新式脫扣器,半導體式脫扣器克服了熱-電磁式脫扣器整定校正困難、精度低的缺點,它的精度高、耐惡劣環境能力強。可同時實現多種保護、控制為一體的新型電器。
關鍵詞:DW15型萬能式低壓斷路器、半導體脫扣器、分勵脫扣器、欠壓脫扣器
The Design of Semiconductor Release
Abstract: A semiconductor Release is an unit of the low-voltage breaker virtually, its function is that it protects familiar malfunctions from the low-voltage circuitry mainly, for example over-loading、insufficient-voltage and short-circuit. With the semiconductor component being devlopped,it is forming a new type of the Releases on the basis of calorifics and electromagnetism. It overtakes the disadvantages of the calorific-electromagnetic Release which it is difficulty to be adjusted and its precision is low. A semiconductor Release is provided with high precision, and be able to bear bad environments strongly, it is a new type of the integrative wiring which can combine safeguards and controls synchronously.
Keywords:DW15 type of multipurpose low-voltage breaker 、semiconductor Release、over-current Release、insufficient-voltage Release
