Problems solved by technology

[0006] For this reason, the technical problem to be solved by the present invention is that the existing polarity conversion circuit adopts discrete electronic components to be affected by the electromagnetic influence of the external environment and the circuit itself, and has poor reliability and low safety. Electric energy is held in a holding state, thereby proposing an energy-saving magnetic holding contactor

Abstract

The invention provides a magnetism holding contactor which comprises a transmission rod. A movable contact is arranged at the top end of the transmission rod. A static contact is correspondingly arranged above the movable contact. A first magnetic force part is arranged at the bottom end of the transmission rod. A second magnetic force part is arranged corresponding to the first magnetic force part. An electromagnetic device is arranged on the outer side of the first magnetic force part and the moving track of the first magnetic force part. Under the action of the electromagnetic device, the first magnetic force part is matched with the second magnetic force part to drive the transmission rod to move upward so as to enable the movable contact to be in touch with the static contact. A reset spring is further arranged outside the transmission rod. The electromagnetic device is connected with a polar conversion circuit. The polar conversion circuit comprises a conversion circuit and a time delay circuit and is mainly composed of a relay and an electronic chip. The magnetism holding contactor is high in stability and reliability, and strong in ability to resist external interference, and can achieve the purpose of control without changing a control circuit due to the fact that the polar conversion circuit is further arranged at the front end of a coil of the electromagnetic device.

Description

technical field [0001] The invention relates to a magnetic holding contactor. It belongs to the technical field of low-voltage electric appliances. Background technique [0002] The magnetic holding contactor is a new type of relay developed in recent years, and it is also an automatic switch. Like other electromagnetic relays, it can automatically switch on and off the circuit. The difference is that the normally closed or normally open state of the magnetic latching contactor is completely dependent on the action of the permanent magnet, and the switching state of the contactor is triggered by a pulse electric signal of a certain width. [0003] The open and closed state of the magnetic holding contactor is usually maintained by the magnetic force generated by the permanent magnet. When the contacts of the relay need to be in the open or closed state, it is only necessary to excite the coil with a positive (reverse) DC pulse voltage, and the relay completes the state tr...
