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
