Vacuum interrupter, have another name called vacuum switch tube, it is the core component of mesohigh power switch, its Main Function is, by can blow-out suppress electric current rapidly after managing the excellent insulating properties of interior vacuum and making mesohigh circuitry cuts power supply, avoid accident and unexpected generation, be mainly used in the power transmission and distribution control system of electric power, be also applied to the distribution systems such as metallurgy, mine, oil, chemical industry, railway, broadcast, communication, industrial high-frequency heating.There is energy-conservation, material-saving, fire prevention, explosion-proof, volume is little, the life-span is long, maintenance cost is low, the feature such as reliable and pollution-free.。
Vacuum interrupter is primarily of part composition ceramic package vacuum interrupters such as airtight insulation crust, conducting system, shielding harness, contact, bellowss.Determine conducting rod, surely run cambered surface, determine contact, moving contact, dynamic run cambered surface, conducting system that moving conductive rod constitutes arc control device.Wherein determine conducting rod, surely run cambered surface, determine the weighed electrode of contactor, moving contact, dynamic race cambered surface, moving conductive rod are collectively referred to as moving electrode, the vacuum circuit-breaker be assembled into by vacuum interrupter, when vacuum load switch and vacuum contactor close a floodgate, operating mechanism is by the motion of moving conductive rod, make two contact closure, complete the connection of circuit.Reduce and keep stablizing when bearing dynamic current with arc control device have good mechanical strength as far as possible to make the contact resistance between two contacts, vacuum switch is provided with fairlead in moving conductive rod one end, and use one group of Compress Spring, make between two contacts, to maintain a rated pressure.When vacuum switch breaking current, arc control device two contact is separated and produces electric arc betwixt, until arc extinction during electric current natural zero-crossing, just completes cut-offfing of circuit.
Although be provided with fairlead in moving conductive rod one end, but it is steady dynamic conducting rod stretching motion in housing, can take regular exercise due to moving electrode and clash in stationary electrode, both may be caused between moving contact and moving conductive rod to connect because of impacting for a long time unstable, finally make to offset between moving contact and fixed contact, when causing arc extinguishing, electric arc burns uneven between contact, causes decline the useful life of moving electrode, so the connective stability of moving electrode itself is to be improved.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of moving contact and moving conductive rod stable connection, the moving electrode of the vacuum interrupter of long service life.
For achieving the above object, the utility model provides following technical scheme: a kind of moving electrode of vacuum interrupter, comprise moving contact, moving conductive rod, described moving contact is provided with welding hole, described moving conductive rod is provided with the welding section matched with welding hole, described moving contact is provided with in the face of moving conductive rod side the gathering sill coaxially arranged with welding hole, and described gathering sill is greater than welding hole size, and described moving conductive rod is provided with the guide section coordinated with gathering sill.
Further, if described guide section excircle is intervally distributed with the dry strip groove axially arranged, the length of strip groove is greater than the degree of depth of gathering sill.
Further, be evenly distributed with some sensing grooves around the welding hole of described moving contact, described sensing groove runs through moving contact both ends of the surface.
As concrete scheme of the present utility model, the end face of described moving contact gathering sill is dorsad provided with connectivity slot, and described connectivity slot is communicated with welding hole and points to groove.
Concrete, be provided with filler in described strip groove.
By adopting technique scheme, due to the cooperation of gathering sill and guide section, especially gathering sill is greater than welding hole size, make contact area between gathering sill sidewall and guide section perisporium larger, make to connect between moving contact and moving conductive rod more stable, the axiality of guarantee moving contact that can be permanent and fixed contact, arc energy is efficiently controlled homogenous combustion in whole contact gap, effectively improves the useful life of moving electrode.

Embodiment
Referring to figs. 1 through Fig. 8, the moving electrode embodiment of a kind of vacuum interrupter of the utility model is described further.
A kind of moving electrode of vacuum interrupter, comprise moving contact 1, moving conductive rod 2, moving contact 1 is provided with welding hole 11, moving conductive rod 2 is provided with the welding section 21 matched with welding hole 11, moving contact 1 is provided with the gathering sill 12 of the coaxial circle arranged with welding hole 11 in the face of moving conductive rod 2 side, the diameter of described gathering sill 12 is greater than welding hole 11 size, and moving conductive rod 2 is provided with the guide section 22 coordinated with gathering sill 12.During connection, the welding section 21 of moving conductive rod 2 is inserted into the welding hole 11 on moving contact 1, now guide section 22 and gathering sill 12 closely cooperate, effectively axiality can be ensured during welding, in use, because guide section 22 is compared larger in the past with the contact area of gathering sill 12, so moving contact 1 is when colliding with fixed contact, the relative moving conductive rod 2 of moving contact 1 is more difficult to produce circumference and rocks, and namely moving contact 1 is relative with moving conductive rod 2 more stable.Can be right when such moving contact 1 contacts with fixed contact at every turn more accurate, the axiality of guarantee moving contact 1 that can be permanent and fixed contact, makes electric arc be efficiently controlled homogenous combustion in whole contact gap, effectively improves the useful life of moving electrode.
After moving conductive rod 2 and moving contact 1 assemble, guide section 22 combines with gathering sill 12, as shown in Fig. 5 to Fig. 8, if be intervally distributed with the dry strip groove 23 axially arranged on guide section 22 excircle, the length of strip groove 23 is greater than the degree of depth of gathering sill 12, the part of such strip groove 23 is exposed to outside gathering sill 12, and one is, under moving conductive rod 2 has enough strength conditions, alleviate the quality of moving conductive rod 2; Two come to be can add filler to this strip groove 23, and this filler can be glue, play solidification, the stable effect connected, and also can be to carry out very strong intensity as metals such as CuCr alloys and regulate the axiality of moving contact 1 and moving conductive rod 2.
Be evenly distributed with some sensing grooves 13 around the welding hole 11 of moving contact 1, described sensing groove 13 runs through moving contact 1 both ends of the surface, and that points to groove 13 arranges the eddy current that can effectively suppress alternating current to produce, and obviously strengthens the magnetic control ability to vacuum arc.
According to further preferred embodiment, as shown in Figure 8, the end face of moving contact 1 gathering sill 12 is dorsad provided with connectivity slot 14, connectivity slot 14 is communicated with welding hole 11 and points to groove 13, this is conducive to strengthening longitudinal magnetic field further, and effectively can extend current path, and effectively suppresses eddy current further.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
