Abstract
Contactor technical field is the utility model is related to, specifically, is related to a kind of built-in electrical insulation high-voltage DC contactor.Existing contactor, when normally opened contact closes, touch panel and static contact contact are moved, has high-tension current between static contact and dynamic touch panel, electric current forms high-tension current circuit by moving axis-dynamic iron core-oilless bearing-iron cup-magnetic conductive board-moving axis, and inner body is damaged.The utility model avoids high-tension current and inner body is damaged by setting felt pad to can effectively solve the problem that contactor internal high pressure current loop between dynamic iron core and oilless bearing.
Description
Technical field
Contactor technical field is the utility model is related to, specifically, is related to a kind of built-in electrical insulation high-voltage DC contactor.
Background technology
Contactor is divided into A.C. contactor (AC) and D.C. contactor (DC), it is applied to electric power, distribution and electricity consumption.Contact
Device generally refers to flow through current induced magnetic field using coil, makes contact closure, to reach the electric appliance of control load.
After contactor coil is powered, coil current can produce magnetic field, and the magnetic field of generation makes static iron core produce electromagnetic attraction
Attract dynamic iron core, and drive contactor point to act, normally opened contact closure.When the coil is de-energized, electromagnetic attraction disappears, and armature is being released
Put and discharge under the action of spring, restore contact, normally opened contact disconnects.
Existing contactor, when normally opened contact closes, moves touch panel and static contact contact, has height between static contact and dynamic touch panel
Current voltage, electric current forms high-tension current circuit by moving axis-dynamic iron core-oilless bearing-iron cup-magnetic conductive board-moving axis, right
Inner body damages, and influences the insulation safety between high-pressure system and low-pressure system.
Utility model content
1st, technical problems to be solved
The problem of damaging inner body for internal high pressure current loop, it is high that the utility model provides a kind of built-in electrical insulation
D.C. contactor is pressed, it can effectively solve the problem that phenomenon of the electric current to internal damage parts or insulation damages, improves product and continuously divides
The service life of disconnected work.
2nd, technical solution
The purpose of this utility model is achieved through the following technical solutions：
A kind of built-in electrical insulation high-voltage DC contactor, including stem, binding post lower end are equipped with positioned at static contact in iron cup,
Static contact is correspondingly provided with dynamic touch panel, and dynamic touch panel is connected with moving axis one end, and moving axis other end connection iron core, is moved between touch panel and iron core
Equipped with magnetic conductive board, iron core is set on oilless bearing, and felt pad is equipped between oilless bearing and iron cup.
Preferably, felt pad is affixed on iron bottom of a cup portion.
Preferably, felt pad is silicon rubber, thickness is 0.1~1mm.
3rd, beneficial effect
Compared with the prior art, the utility model has the advantage of：
1st, a kind of built-in electrical insulation high-voltage DC contactor of the utility model, when its continuous disjunction works, normally opened contact phase
The closure answered disconnects, and when dynamic touch panel and static contact contact, iron core moves upwards, and iron core is still sleeved on oilless bearing, and moving axis, move
