Content of the present invention
Purpose of the present invention is intended to overcome the deficiency of prior art, provides a kind of and bears that voltage is higher, contact is difficult for easy oxidation, simple in structurely is convenient to process and oil immersed high-voltage relay that cost is low.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of oil immersed high-voltage relay, comprise following insulating sleeve and interior moving contact thereof, go up insulating sleeve and interior fixed contact thereof, the coil windings and the baffle plate of insulating sleeve bottom down, also comprise the conducting ring that is positioned at the insulating sleeve bottom, described moving contact is made up of conductive pole that is with spring and iron core.
Described conducting ring has perforate with following insulating cylinder junction, can insert high-voltage line by latch, introduces external high pressure.There are compression spring and steel ball in conducting ring and following insulating sleeve junction, and the elastic force by compression spring is pressed on the conductive pole outer wall of moving contact with steel ball, is used for making conductive pole closely to contact with the latch of access high-voltage line.
Described fixed contact upper end is a conductive pole, and the bottom has been the contact reed of buffering and electric action.
Be filled with insulating oil in the cavity volume between described moving contact and the fixed contact.
Its outside, following insulating sleeve bottom is wound with coil windings, by baffle plate coil windings is kept off in the bottom of descending insulating sleeve.
A kind of oil immersed high-voltage relay of the present invention, it is positioned at the conducting ring of insulating sleeve bottom, introduce high-voltage line by perforate, press the high-voltage line that conductive pole and outside are introduced to contact well by compression spring and steel ball, solve introducing external high pressure problem well, made a kind of oil immersed high-voltage relay of the present invention can bear high voltage; Insulating oil in the cavity volume between moving contact and the fixed contact is immersed in the insulating oil contact position of moving contact and fixed contact, and contact is difficult for easy oxidation, has prolonged useful life; The contact reed of its fixed contact is promptly done to conduct electricity and the effect that cushions fixed contact and moving contact contact action is arranged, and has reduced high-voltage relay volume and simple structure, and processing cost is low.

Fig. 1 is a structural representation of the present invention,
1-moving contact among the figure, 2-fixed contact, 3-coil windings, the last insulating sleeve of 4-, insulating sleeve under the 5-, 6-baffle plate, the 7-conducting ring, 8-spring, 9-conductive pole, the 10-iron core, 11-compression spring, 12-steel ball, the 13-perforate, 14-conductive pole, 15-contact reed, the 16-insulating oil, 17-high pressure latch, 18-high-voltage line.
Embodiment
In order to understand the present invention better, it is done explanation in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a specific embodiment of a kind of oil immersed high-voltage relay of the present invention, structure comprises following insulating sleeve 5 and interior moving contact 1 thereof, go up insulating sleeve 4 and interior fixed contact 2 thereof, the coil windings 3 and the baffle plate 6 of insulating sleeve 5 bottoms down, described moving contact 1 is made up of conductive pole 9 that is with spring 8 and iron core 10, also comprises the conducting ring 7 that is positioned at insulating sleeve 4 bottoms.
Conducting ring 7 has perforate 13 with following insulating sleeve 6 junctions, and the external high pressure line can be introduced from perforate 13 by the high pressure latch 17 that adopts among the embodiment; Conducting ring 7 has compression spring 11 and steel ball 12 with following insulating sleeve 5 junctions, and the elastic force by compression spring 11 is pressed on conductive pole 9 outer walls of moving contact 1 with steel ball 12, and conductive pole 9 is closely contacted with the latch 17 of access high-voltage line.
Strong bar magnet 8 is arranged in its moving contact 1, and there is conductive layer its outside.Moving contact 2 is provided with conducting ring 1 with last insulating sleeve 5 junctions, and strong bar magnet 8 one ends are enclosed within conducting ring 1 interstitial hole.Conducting ring 1 has perforate with following insulating sleeve 6 junctions,, conducting ring 1 and following insulating sleeve 6 junctions also have steel ball 10, and it closely contacts the pressure by compression spring 9 with moving contact 2.
Conductive pole 9 passes from conducting ring 7 inside; Spring 8 is enclosed within on the conductive pole 9, and an end is fixed on conductive pole 9 bottoms, and the other end blocks by conducting ring 7.
Fixed contact 2 is made up of conductive pole 14 and continuous contact reed 15, and fixed contact 2 upper ends are conductive pole 14, and conductive pole 14 bottoms are that contact reed 15 plays conduction and buffering.
Be filled with insulating oil 16 in the cavity volume between moving contact 1 and the fixed contact 2.
It is wound with coil windings 3 in insulating sleeve 5 bottoms down, and is followed closely in the bottom of following insulating sleeve by the screw in the middle of it by baffle plate 6, thereby blocks coil windings 3.
During work, coil windings 3 is connected with low tension, when electric current reaches a certain size, generate an electromagnetic field, magnetic field force promotes iron core 10 motions, and iron core 10 promotes conductive pole 9 motions, spring 8 tensionings simultaneously, the conductive pole 9 of moving contact 2 moves to contact reed 16 places of fixed contact 3 and also closely contacts with it, and the high-tension electricity that the high pressure latch 17 of conducting ring 7 tappings is introduced conducts in conductive pole 9, and conductive pole 9 is with the conductive pole 14 of high-tension electricity by 15 conduction of contact reed and fixed contact 2; When coil windings 3 low tensions disconnected, magnetic field force disappeared, and spring 8 is because elastic deformation produces restoring force, promote the downward insulating sleeve bottom motion of conductive pole 9 bottoms, make conductive pole 9 get back to the origin-location, thus disconnect with contact reed 15 contact the high-tension electricity at disconnection fixed contact 2 places.
Owing to adopt oil immersed type at high-voltage relay of the present invention, moving contact 1 and fixed contact 2 contact positions are immersed in the insulating oil 16, oil when action between the contact plays the effect of heat radiation and insulation, the generation of having controlled electric arc, simultaneously owing to there is not oxygen, thereby the contact can oxidation, has prolonged the useful life of relay; The contact reed 15 of cushioning effect is arranged in fixed contact 2 bottoms, also play electric action, reduced volume and simple structure, processing cost is low; By compression spring on the conducting ring 7 11 and steel ball 12 conductive pole is contacted well with the outside high-voltage line of introducing, make a kind of oil immersed high-voltage relay of the present invention can bear high voltage.
