Abstract
The invention relates to an equidirectional dual-thrust electromagnetic relay, which consists of a main body, an electromagnetic contact, a permanent magnet and double spring plates. Input ends of two upper and lower contacts of the main body are connected with an input power, while output ends thereof are adapted with the electromagnetic contact. The electromagnetic contact is fixed between the output ends of the two contacts of the main body by rotating contenting points. A lower end of a static spring plate of the double spring plates is connected on a phase output end. An upper end of a dynamic spring plate of the double spring plates is fixedly connected with an upper end of the static spring plate, while a lower end thereof is linked with the permanent magnet. The permanent magnet takes a shape of right-angle trisquare. The permanent magnet connected with a connecting end of a conducting strip is arranged on one side, and a static contact fixedly connected with the dynamic spring plate of the double spring plates and a dynamic contact movably connected with the static spring plate of the double spring plates are arranged on the other side. The invention has meticulous design and light and reliable structure, realizes improvement of the functions of the relay by using the basic physical principles, has high practical value and can effectively improve the working reliability of the electric power circuit.
Description
Technical field
A kind of Equidirectional dual-thrust electromagnetic relay that overcomes short circuit current repulsion
Background technology
Electromagnetic relay is a kind of electromechanical compo, is widely used in various electric power systems and the electric supply installation.The relay of band permanent magnet changes the relay operating state by pulse signal, saves energy not only, and also operating state is reliable.In the power circuit, during relay power, powerful because of electric current in the circuit, the contact contacts moment, can produce powerful short circuit current between the contact.This short circuit current can produce the repulsion opposite with closing of contact power, and the closing force of disturbing permanent magnet to produce makes the contact sometimes can not be effectively closed, even rebound, and therefore produces hard arc, fusion and burn the contact, and the damage relay influences the supply of electric power.。
Summary of the invention
The objective of the invention is design by a kind of Equidirectional dual-thrust electromagnetic relay, make it not only have the function of traditional electrical magnetic relay, and work as its contact under the effect of pulse signal, when carrying out closed action, the closed thrust that permanent magnet produces is consistent because of " repulsion " direction that electric arc produces with moving contact, guarantees that the contact is effectively closed.
The present invention is made up of body, electromagnetic contact, permanent magnet, dual spring sheet, and upper and lower two the contact inputs of body connect the input power supply, and output and electromagnetic contact connect, and electromagnetic contact is fixed between the body two contact outputs by rotary contact; Quiet spring leaf lower end in the dual spring sheet is connected on the phase output terminal, and the reed upper end of moving in the dual spring sheet is affixed with quiet spring leaf upper end, and the lower end is connected with permanent magnet; Permanent magnet is a right angle trisquare shape, Yi Bian be the permanent magnet that is connected with the conducting strip link, another side for the affixed fixed contact of dual spring sheet moving plate and with the moving mutually moving contact that connects of dual spring sheet still.
Electromagnetic contact is formed by two contact chip configured in parallel, and the centre is the rotation node of charged magnetic coil, and being located at intrinsic contact chip is banking stop, and being located at this external contact chip is conducting strip, and the conducting strip lower end is provided with link;
The dual spring sheet is made up of the quiet spring leaf and the reed of moving, and the quiet spring leaf and the reed upper end of moving are fixed together, and the flexible distortion of quiet spring leaf epimere is arciform curved, and the lower end is a moving contact.
The course of work of the present invention is as follows:
When electromagnetic contact moves under the pulse signal effect, permanent magnet is under the stirring of electromagnetic contact conducting strip link, contact with body below live contact, the quiet spring leaf in the dual spring sheet is when closing contact, and the repulsion of generation is identical with the resultant direction that permanent magnet produces.Two power additions, thus can effectively overcome the electric arc repulsion that produces when permanent magnet and body below live contact contact, guarantee the contact effectively, connection reliably.
The present invention conceives careful, and structure is light and handy, reliable, by using the basic physics principle, realizes the improvement and the raising of relay function, has very high practical value, can effectively improve the functional reliability of power circuit.
