Switch, electronic system, power system, automatic system, mechanical device, measuring device and labour protection air-exhausting device

Abstract

A switch comprises an insulated container (1), a liquid metal (2), resistance liquid (3), a capacitance plate (4), a pole plate insulating layer (5), an inductor (6), a first connecting point (Y plus), a second connection point (Y minus), and electric insulating oil. An electronic system is provided with the above switch. A power system is provided with the switch. An automatic system is provided with the electronic system and the power system above. A mechanical device is provided with an electrical machine and the switch above. A measuring device is provided with the mechanical device above. A labour protection air-exhausting device is provided with the electric machine, an exhaust air duct, an exhaust fan and the switch above. The switch, the electronic system, the power system, the automatic system, the mechanical device, the measuring device and the labour protection air-exhausting device of the invention are simple in structure, long in service life and low in cost.

Description

technical field [0001] The invention belongs to electric power, electronics, or mechanical devices with electric energy, and in particular relates to switches, electronic systems, power systems, and mechanical devices. Background technique [0002] The start-up surge will have a huge interference and impact on the electronic and power systems, and may even cause system damage or paralysis. The existing methods of combating the start-up surge are generally achieved by using static devices such as transient suppression diodes, but these static devices It is easy to be damaged, and most of the static components do not complete a surge suppression task, and their own life will be shortened, and the cost of anti-surge and anti-surge devices for electromechanical equipment in the prior art is relatively high. The present invention proposes a switch. It can effectively reduce (anti-surge) start-up surge and protect electronic and power systems. Contents of the invention [0003]...
