Problems solved by technology

[0012] 1. Unnecessary power consumption: As mentioned above, in the pull-in and hold stages, the "same" AC voltage is passed through the excitation coil of the conventional AC contactor, which makes the hold power too large, resulting in unnecessary electric energy loss;
[0013] 2. Heating: The evil result of unnecessary power loss is "heating and heating". In severe cases, it will even burn the excitation coil of the conventional AC contactor;
[0014] 3. There is annoying AC noise;

Abstract

The present invention discloses an energy-saving alternating current contactor using a special-shaped bridge and an auxiliary contact. The energy-saving alternating current contactor includes a regular alternating current contactor consisting of a movable contact, a normally closed contact, a normally open contact, a movable iron core, a static iron core, a reset spring, an excitation coil and a normally open auxiliary contact, and an electronic unit.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a "power-saving AC contactor using a special-shaped bridge and an auxiliary contact" which uses a special-shaped bridge and an auxiliary contact to realize high efficiency and power saving. Background technique [0002] Alternating Current Contactor (Alternating Current Contactor) is a low-voltage electrical appliance that is widely used. As of 2015, there are more than one billion AC contactors running online in my country, and the number is increasing at an annual rate of 80 million. Its working principle is to use the electromagnet to drive the movable contact to separate or close the normally closed contact or normally open contact, so as to cut off or connect the circuit. It is suitable for starting or controlling three-phase induction motors and other electrical equipment. [0003] figure 1 It is a working principle diagram of a conventional AC contactor. ...
