Abstract

The invention discloses a micro-power consumption and zero-noise contactor with a power-losing protection function. The micro-power consumption and zero-noise contactor is mainly composed of an electromagnet, a movable contact supporting frame, a positioning trench, a movable contact, a fixed contact, a power-losing protection system and the like. The contactor interacts with the positioning trench through a control pin, an electromagnetic coil can be powered up once instantaneously, the contactor is in a connected state, then the electromagnetic coil is powered up once again, and the contactor is in a disconnected state. Consequently, the defect that when an original contactor electromagnetic coil works along with an electric appliance, electricity can be consumed certainly can be effectively overcome, and electric energy can be effectively saved. The contactor is in a mute state in the working process, noise pollution can be effectively lowered, and it is of positive significance to saving energy and lowering noise pollution after implementation.

Description

technical field [0001] The invention relates to commonly used control electrical appliances in industrial production, in particular to a micro-power consumption and zero-noise contactor with power-off protection function, which belongs to the field of low-voltage electrical appliances. Background technique [0002] There are many types of contactors, including AC contactors, DC contactors, permanent magnet contactors, relays, etc., which are mainly used for long-distance frequent switching on and off circuits or control systems. In particular, AC contactors are used in the largest amount in control electrical appliances. This contactor uses an electromagnet to pull multiple sets of contacts. When the electromagnet pulls in, the contact is closed and the electric appliance works. On the contrary, the electromagnet loses power, and the electric appliance stops working. That is to say, when the electrical appliance needs to work, the electromagnet must also be in a state of ...
