In further embodiment of the present invention, electromagnetic assembly includes electromagnet 20 and dynamic iron core 21, and electromagnet 20 is set to outer
The other side of shell 11, dynamic iron core 21 are movably arranged in electromagnet 20, and the other end of drive rod 14 is fixedly connected with dynamic iron core 21.It is excellent
Selection of land, driving mechanism of the invention is electromagnetic drive, but is not limited only to electromagnetic drive, can be pneumatic actuation.
Preferably, the material of shell 11 is synthetic resin material, is not only able to satisfy requirement on electric performance, but also be able to satisfy best ecology
It is required that the material is fire-retardant, nontoxic, non-environmental-pollution.
Making process of the invention: when electromagnet 20 is powered, dynamic iron core 21 is pushed to act, to drive drive rod 14
It is dynamic, 3 activity of movable contact rod 4 and movable contact block is driven, so that moving contact 2 is mobile to static contact 1, the top of moving contact 2 and stationary contact
After first 1 upper contact, pre- conjunction state is realized, moving contact 2 continues to move to, until the lower part of the lower part of moving contact 2 and static contact 1
Contact, the top of moving contact 2 and the top of static contact 1 separate, and complete to close a floodgate.
Separating brake process of the invention: when 20 power loss of electromagnet, dynamic iron core 21 discharges, the subsequent linkage of drive rod 14 release,
Driving movable contact rod 4 and movable contact block 3 discharge together, so that moving contact 2 is removed to static contact 1, the top of moving contact 2 and stationary contact
After first 1 upper contact, pre- isloation state is realized, moving contact 2 continues to remove, until moving contact 2 is removed completely with static contact 1, it is complete
At separating brake.
When contact assembly is converted to pre- conjunction state by opening state, the process for thering is moving contact 2 to roll along static contact 1,
The maximum function of this process is the oxide layer for eliminating contact surface；When the complete "on" position of contact assembly, contact can be appreciated that at this time
Lower contacts it is conductive.
When contact assembly is converted to pre- isloation state by "on" position, the top on the top of moving contact 2 and static contact 1 at this time
Contact forms arcing contact, if if opening again, electric arc 22 is just formed on the top of moving contact 2 and the top of static contact 1, ensure that
The lower part of moving contact 2 and the lower part of static contact 1 are not damaged by electric arc 22, ensure that the good contact of contact after closing a floodgate in this way.
Arc leading angle is moved upwards up to by the diagram direction F due to the effect of electric current after the formation of electric arc 22, at this time due to arc blow-out line
Electric arc 22 is quickly pulled into arc-extinguish chamber 16 by the effect of coil assembly 17, and electric arc 22 is divided into a series of short arcs by grid component 18,
Then electric arc 22 is made to accelerate cooling until extinguishing.
If the electric current very little (being lower than 50A) of main circuit, then illustrate the upward power very little of F, then electric arc 22 is difficult to be detached from
The top of moving contact 2 and stationary contact 1 top, it is by magnetic field force caused by blowout coil component 17, electric arc 22 is de- rapidly
The top on top and static contact 1 from moving contact 2, hence into arc-extinguish chamber 16, arc extinguishing success.
The work of contact assembly of the invention is to support compression spring 5 according to the principle being in rolling contact and be set to movable contact rod 4
Between movable contact block 3, there is rolling action when static contact 1 and moving contact 2 are closed, is rolled in entire moving contact along static contact 1
In dynamic process, lower part and static contact 1 of the upper contact reconvert on the top and static contact 1 of realizing moving contact 2 at moving contact 2
Lower contacts, have to contact surface and remove oxide layer effect, being in rolling contact keeps the lower part of contact conductive, the top starting the arc of contact
Contact effect, the lower part of the lower part and static contact 1 that ensure that moving contact 2 are not damaged by electric arc 22, ensure that contact after combined floodgate
Good contact, improves the service life of contact.
Blowout coil component 17 is arranged in the present invention, by magnetic field force caused by blowout coil component 17, electric arc 22 is fast
Speed is detached from the top of moving contact 2 and the top of static contact 1, hence into arc-extinguish chamber 16, it is ensured that quickly and effectively arc extinguishing.
The present invention is for the line contactor of locomotive and train, integration module containing line contactor/isolation contactor and in advance
