Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency present in prior art, and provides a kind of reasonable in design, and installation and removal are convenient, and production technology is simple, safe and reliable HVDC relay.
The technical scheme in the invention for solving the above technical problem is: the movable contact assembly in this HVDC relay, including contact stage clip, jump ring, big spring and packing ring, it is characterized in that: also include movable contact, insulated leg, upper end cover, rustless steel pole and dynamic magnetic core, one end of described rustless steel pole sequentially passes through upper end cover, insulated leg and movable contact, the other end of this rustless steel pole contacts with dynamic magnetic core, jump ring is arranged between the top of movable contact and rustless steel pole, big spring is socketed with rustless steel pole, packing ring is between contact stage clip and insulated leg, the lower section of movable contact is provided with contact stage clip；Reasonable in design, installation and removal are convenient, and service life is long, safe and reliable.
As preferably, dynamic magnetic core described in the utility model is provided with open slot, and this open slot is axially arranged；When dynamic magnetic core moves up and down, if unslotted, gap is little, produces resistance, and air flows, it is simple to aerofluxus, and action is fast, increases the speed of contact, reduces resistance.
As preferably, the outer rim of insulated leg described in the utility model is provided with a circle chimb；Storehouse, contact is provided with a circle concave edge, insulated leg and storehouse, contact and is assembled by this chimb and concave edge；It is easy to assembling.
As preferably, the structure of insulated leg described in the utility model is widened and is provided with groove；For depositing slag.
As preferably, movable contact described in the utility model is coated with one layer of fine silver；In order to anti-oxidation, reduce contact resistance, make relay entirety caloric value reduce.
This utility model compared with prior art, has the following advantages and effect: 1, rational in infrastructure, and installation and removal are convenient, and production technology is simple, safe and reliable；2, the open slot effect on dynamic magnetic core: when dynamic magnetic core moves up and down, if unslotted, gap is little, produces resistance, and air flows, it is simple to aerofluxus, and action is fast, increases the speed of contact, reduces resistance；3, it is coated with one layer of fine silver on movable contact, in order to anti-oxidation, reduce contact resistance, make relay entirety caloric value reduce.
