an electromagnetic switch

Abstract

The invention discloses an electromagnetic switch. The anode of a power supply is fixedly connected with an internal A wiring terminal through a wire, the negative electrode of the power supply is fixedly connected with an internal D wiring terminal through a wire, a copper wire A interface is fixedly connected with an internal C wiring terminal and an internal F wiring terminal through wires respectively, and a copper wire B interface is fixedly connected with an internal B wiring terminal and an internal E wiring terminal through wires respectively. The direction of current is changed through the mechanical switch, then the magnetic poles of electromagnets are changed, when the switch needs to be closed, the mechanical switch changes the direction of the current, the magnetic poles of electromagnets are further changed, the homopolar attracting of the electromagnets is utilized, and therefore conductive copper cores in iron cores are in butt joint with each other, and then alternating current is switched on; and when the switch needs to be switched off, the homopolar repulsion is utilized to separate the conductive copper cores in the iron cores, then the alternating current isswitched off, the direction of the current is changed in a mechanical mode, then the magnetic poles of the iron cores is changed, and the automatic work of the electromagnetic switch is realized.

Description

technical field [0001] The invention relates to the field of smart electric technology, in particular to an electromagnetic switch. Background technique [0002] The current switch usually needs to be manually controlled. Due to the relatively large current, the knife switch will generate an arc (electric spark) at the moment of closing and closing. The greater the operating current, the stronger the arc will be. In severe cases, fire and light can hurt people. , will have a great impact on human safety; the internal fuse of the knife switch and the contact parts and contacts installed by the wires are easy to age and oxidize, which will increase the contact resistance and generate heat, which will aggravate the aging, cause waste of electric energy, and cause power outages in severe cases Faults cause great inconvenience to life; therefore, an electromagnetic switch is needed, which can be operated remotely, and at the same time realizes low-voltage control of high-voltage ...
