Specific embodiment
Referring to Fig.1, a kind of high voltage isolator anti-automatic closing device proposed by the present invention, comprising: snap ring 1 and insulation branch
Support member 2.Protective case 1-1 is arranged on snap ring 1, insulated support 2 connect with snap ring 1 and perpendicular to 1 place plane of snap ring.
In this way, snap ring 1 is propped up by insulated support 2, snap ring 1 is inserted in from disconnecting switch connecting lever upper end when work,
As shown in Figure 2.The the aperture of disconnecting switch connecting lever the bigger down when due to gate-dividing state, is finally fixed at and keeps apart to snap ring 1
When closing on connecting lever, it is ensured that the stable type that connecting lever folds prevents plug-in strip from closing a floodgate.
In present embodiment, snap ring 1 be open annular structure, with facilitate adjust 1 size of snap ring, thus meet it is different every
Leave the anti-combined floodgate demand of banding of connecting lever at pass.
In present embodiment, snap ring 1 is made of the first arc bar, the second arc bar and telescopic rod, the first arc bar and the second arc bar
The both ends and opening for being separately mounted to telescopic rod are oppositely arranged.In this way, can realize snap ring 1 by adjusting length of telescopic bar
Big minor adjustment.Specifically, telescopic rod uses telescopic spring bar, so that snap ring 1 is adjusted automatically when being locked connecting lever in present embodiment
Save size.
In present embodiment, female connector 1-2 is installed on snap ring 1, insulating support rod top is equipped with and female connector 1-2
The pin end 2-4 matched passes through female connector 1-2 and pin end 2-4 dismantling connection between insulated support 2 and snap ring 1.In this way,
After snap ring 1 puts on connecting lever, operation maintenance personnel can easily remove insulating support rod, reassemble new snap ring 1 and complete another phase plug-in strip
Anti- closing device assembly manipulation.
In present embodiment, pin end 2-4 uses magnetic material, in this way, insulating support rod passes through when dismantling snap ring 1
Magnetic pin end 2-4's and female connector 1-2 attracts each other, and the efficiency that insulating support rod is connect with snap ring 1 can be improved, to improve
Working efficiency.
In present embodiment, female connector 1-2 is mounted on 1 middle part of snap ring, to guarantee to prop up snap ring 1 by insulating support rod
When, the stabilization of snap ring 1.
In present embodiment, the bottom end of insulated support 2 is equipped with insulated handle 2-1, also installs at the top of insulated handle 2-1
There is parachute skirt 2-2.In this way, when using the device, staff holds insulated handle 2-1, and parachute skirt 2-2 plays antifouling
Effect can prevent from forming access, protection staff's peace by rainwater between equipment live part and human body in unexpected rain
Entirely.Specifically, parachute skirt 2-2 uses antifouling silica gel full skirt in present embodiment.
In present embodiment, insulating support rod is by the more pole 2-3 between pin end 2-4 and parachute skirt 2-2
Be linked in sequence composition.In this way, facilitating according to power distribution equipment height, pole 2-3 is flexibly matched, to total Gao Jinhang of insulating support rod
Adjustment.Meanwhile the device is also removable is divided into multiple assembly parts, easy to carry, assembling.
In present embodiment, insulating support rod, handle are made of high-strength insulating material, after each component is assembled to position,
It can be moved easily.Since the device job area is small, avoided in moving process ascend a height, get an electric shock, the danger such as mechanical wounding.And
The device can be used for that various 35kV and following power distribution equipment electrification position are isolated, and working space is small, and use scope is big.
The above, preferable specific embodiment only of the present invention, but protection scope of the present invention not office
