Description
Technical field
The utility model relates to high voltage protective electrical equipment, especially a kind of drop type lightning arrester.
Background technology
Lightning arrester is that transformer station exempts from the protection equipment that lightning surge attacks; When the lightning surge of transformer station is imported on road along the line above the protection of arrester level into; Lightning arrester at first discharges; And, utilize earthing device to make the lightning voltage amplitude limitation below horizontal by protection equipment lightning impulse with the introducing the earth of lightning current through good conductor safety, electric equipment is protected.But lightning arrester also needs to have a power failure when regular maintenance and the dismounting of damage back, therefore can cause economic loss.Existing detachable lightning arrester can only be realized charged dismounting, can not overturn automatically when being out of order.
The utility model content
The purpose of the utility model provides a kind of drop type lightning arrester that falls of can chargedly dismantling at any time, turn over automatically when being out of order.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of drop type lightning arrester; The drop type framework that the following junction block that last junction block that is provided with by insulation column, insulation column top and insulation column bottom are provided with constitutes, last junction block is provided with upper static contact and the high-pressure side binding post that is connected with upper static contact, the lower moving contact that following junction block is provided with down fixed contact and assembles with following fixed contact; Also comprise the detachable lightning arrester; The moving contact on lightning arrester top connects upper static contact, and the support seat of lightning arrester is connected with lower moving contact, and the lightning arrester bottom is provided with the disconnector that is positioned at support seat downside; Disconnector is connected with lower moving contact through lead, and a side of lightning arrester moving contact is equipped with the insulation draw ring.
Upper static contact is that roof pressure is connected with the moving contact of lightning arrester, and the support seat of lightning arrester and lower moving contact are hinged.
Said lightning arrester is a zinc oxide arrester.
Said disconnector is the heat explosion type disconnector.
The described drop type lightning arrester of the utility model has following beneficial effect: 1, through the insulation draw ring, lightning arrester can chargedly load and unload at any time, is particularly suitable for the place that should not have a power failure.2, during the lightning arrester fault, the disconnector fracture, disconnector and lightning arrester can turn over automatically, and be out of service, and the assurance circuit normally moves.3, lightning arrester turns over the obvious fracture of formation during fault, is easy to timely discovery, safeguards and changes.4, lightning arrester adopts composite sheath, and the drop type framework adopts composite post, and hydrophobicity is good, durability against pollution is strong.The described drop type lightning arrester of the utility model is with being installed in dexterously on the drop type framework of fuse switch after the zinc oxide arrester repacking; Reach under powering-off state not; Can easily lightning arrester be detected, safeguard and change by the insulation draw ring of the first side of lightning arrester movable contact; Not only guaranteed the unimpeded of circuit; And reduced electric power maintenance personnel's working strength and time widely, be particularly suitable for the place that should not have a power failure, like post and telecommunications, station, airport, hospital, bustling business district, school etc.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
By a kind of drop type lightning arrester shown in Figure 1; Comprise the drop type framework that the following junction block 7 of the last junction block 3 that is provided with by insulation column 5, insulation column 5 tops and the setting of insulation column 5 bottoms constitutes; Last junction block 3 is provided with upper static contact and the high-pressure side binding post 4 that is connected with upper static contact, and following junction block 7 one sides are provided for directly grounded mounting panel 6, opposite side is provided with down fixed contact 8, are equipped with lower moving contact 15 on the following fixed contact 8; Lower moving contact 15 is provided with bearing pin; Bearing pin is arranged in down in the trip of fixed contact 8, and lower moving contact 15 can on following fixed contact 8, overturn and both constitute a switching mechanism, and the drop type framework is taken from the framework that falls of fuse switch; Be prior art, so be not described in detail.
The described drop type lightning arrester of the utility model also comprises detachable zinc oxide arrester 12; Set gradually moving contact 14, support seat 11 and disconnector 10 on the body of zinc oxide arrester 12 from top to bottom; The moving contact 14 on zinc oxide arrester 12 tops connects upper static contact; Because the last junction block 3 of above-mentioned drop type framework is provided with the top pressure spring 1 of downward roof pressure upper static contact; And upper static contact is provided with the circular arc contact 2 of a under shed, so the moving contact 14 on lightning arrester 12 tops is realized in this circular arc contact being connected with the upper static contact roof pressure through snapping in, the support seat 11 of zinc oxide arrester 12 middle and lower parts and an end of lower moving contact 15 are hinged; The disconnector 10 that zinc oxide arrester 12 bottoms are provided with is connected with lower moving contact 15 circuit through lead 9, and a side of lightning arrester 12 moving contacts 14 is provided with insulation draw ring 13.Said support seat 11 is an insulator, and disconnector 10 is the heat explosion type disconnector.
The described drop type lightning arrester of the utility model has increased disconnector 10 on the basis of detachable zinc oxide arrester, and with being installed in dexterously on the drop type framework of fuse switch after zinc oxide arrester 12 repackings; Reach under powering-off state not; Can detect, safeguard and change lightning arrester 12 easily by insulation draw ring 13, when breaking down unusually appears in lightning arrester 12, utilize the power frequency short circuit current by disconnector 10 actions; Make disconnector 10 fragment into two parts; Earth terminal is thrown off automatically, and lightning arrester Unit 12 turn over, and the accident that prevents out of service further enlarges; Be easy to the staff and in time find and keep in repair and change, shortened interruption duration greatly.Drop type mechanism, contact is reliable, deciliter flexibly.
