Problems solved by technology

[0002] The current AC contactor works on the principle of electromagnetic pull-in. During pull-in and operation, the power consumption is too large, the noise is large, and the coil heats up seriously. In order to overcome the above shortcomings, people are constantly developing energy-saving products, but only in ordinary contact. To improve the structure of the contactor, the patent number: (CN01250002.X) discloses the most representative technology, which adds a set of electromagnetic power system and locking device to the main structure of the ordinary contactor, although there is a certain reduction in consumption The operation effect, but the added device is too complicated to make the stability and reliability worse, and it cannot fundamentally solve the shortcomings of high power consumption and high noise

Embodiment Construction

[0015] The parts purchased in the market and processed by conventional methods are assembled according to the accompanying drawings and the summary of the invention to obtain the present invention.

[0016] The working process of the present invention is described in detail below in conjunction with accompanying drawing:

[0017] First, connect the fixed contact (11) of the self-locking AC contactor to the controlled power supply, and the terminal (18) to the controlled device. When the 220V AC power is turned on, the power supply in Figure 6 1、2 Respectively reach the state control circuit, A-B-C-E-K-L-N and D of K-1, with the gradual completion of the charging and energy storage of the energy storage circuit, the power supply 1 And the voltage of the connected circuit is gradually increasing, and the voltage of the state control circuit changes suddenly after reaching the predetermined value, and K-1 turns on the original power supply 1 -The circuit of A-B-C-E-K-L-N is disc...
