For achieving the above object, this utility model provides following technical scheme: a kind of outdoor AC high-voltage every Leaving pass, including base and conductive plate, it is exhausted that the upper surface both sides of described base are separately installed with the first support Edge and the second supports insulative, the upper end of the first supports insulative and the second supports insulative is respectively equipped with Static contact and moving contact, the medial extremity of static contact uses rolls over design, and described conductive plate is positioned at the first support Between insulator and the second supports insulative, the middle part upper surface of described conductive plate is provided with switch draw ring, leads Electroplax is positioned at switch draw ring and is provided with divide-shut brake stop pin, and the surface of described static contact and conductive plate sets respectively Having the first latch and the second latch, the upper end of described static contact is provided with latch panel, described dynamic The end of contact is silver coated.

Preferably, described first supports insulative and the second supports insulative all use blue disc type to install.

Preferably, the contact apertures of square hole shape is all left at the middle part of described static contact and moving contact.

Preferably, the nameplate of laser engraving it is provided with in the middle part of the front-end surface of described base.

Preferably, the thickness of described silver layer is not less than 20 microns, and hardness is not less than 120 Vickers.

Compared with prior art, the beneficial effects of the utility model are: this outdoor AC high-voltage disconnecting switch Conductive plate there is auto-lock function, can prevent cut-off point from producing strong electric arc, it is ensured that the safety of equipment, Improve magnitude of current during conducting, reduce loop resistance, the first supports insulative and the second supports insulative The good stability of son, the opening degree of conductive plate can regulate, it is ensured that the safety of service work.

Accompanying drawing explanation

Fig. 1 is this utility model structural representation.

In figure: 1 base, 11 nameplates, 2 first supports insulative, 21 static contacts, 211 first latch, 3 second supports insulative, 31 moving contacts, 4 conductive plates, 41 switch draw rings, 42 second latch, 5 Latch panel, 6 divide-shut brake stop pins, 7 silver layers.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this The scope of utility model protection.

Referring to Fig. 1, this utility model provides a kind of technical scheme: a kind of outdoor AC high-voltage disconnecting switch, Including base 1 and conductive plate 4, it is provided with the nameplate 11 of laser engraving in the middle part of the front-end surface of base 1, makes Nameplate 11 content does not forever fall off and damages.Content includes maker, model, factory number, manufacture year Part, rated voltage, specified thunderbolt impulse withstand voltage, rated current, specified KA Rms, volume Determine the number of times etc. mechanical life of the duration of short-circuit, specified patch panel static mechanical loads, disconnecting switch, The upper surface both sides of base 1 are separately installed with the first supports insulative 2 and second supports insulative 3, and first Supports insulative 2 and the second supports insulative 3 all use blue disc type to install, and add the first supports insulative Son 2 and the stability of the second supports insulative 3.Stop twisting dislocation during original disconnecting switch folding Causing a deciliter fault, the upper end of the first supports insulative 2 and the second supports insulative 3 is respectively equipped with quiet Contact 21 and moving contact 31, the middle part of static contact 21 and moving contact 31 all leaves the contact apertures of square hole shape, Can install and have location anti-twisting, loosening cup square neck bolt, the medial extremity of static contact 21 uses rolls over design, During combined floodgate, static contact 21 is directly connected with copper chi；So substantially increase electric conduction flow, reduce back Road resistance, conductive plate 4 at the first supports insulative 2 and second between supports insulative 3, conductive plate 4 Middle part upper surface be provided with switch draw ring 41, conductive plate 4 be positioned at switch draw ring 41 at be provided with divide-shut brake locking Pin 6, after combined floodgate, conductive plate 4 has auto-lock function, Drawing switch draw ring 41 automatic unlocking during separating brake.With Preventing disconnecting switch from automatically disengaging in the middle of running, separating brake causes under high pressure effect, and cut-off point will produce Strong electric arc, and very difficult self-extinguish, in some instances it may even be possible to cause arcing (relatively or phase fault), scaling loss Equipment, jeopardizes personal safety and region and has a power failure the tremendous economic loss brought, static contact 21 and conduction The surface of plate 4 is respectively equipped with the first latch 211 and the second latch 42, and the upper end of static contact 21 is provided with Latch panel 5, the end silver coated 7 of moving contact 31, the thickness of silver layer 7 is not less than 20 microns, Hardness is not less than 120 Vickers, substantially increases electric conduction flow, reduces loop resistance.
