Abstract
The utility model relates to a disconnecting switch insulation hood, which comprises a hood body 1 and is characterized in that one surface of the hood body 1 is provided by the integrating method with an angle supporting element 2 and a supporting box 3, wherein the angle supporting element 2 is positioned below the supporting box and has thereon a hole 5 parallel to the axial direction of a casing body; the other surface of the casing is provided with a positioning groove below. The utility model has the advantages of high insulation, reliable safety and convenient operation. Used in the test of an indoor switch cabinet with 6-10KV switching voltage grade for safety guard, the utility model can directly and reliably function for guarding in case the disconnecting switch falls unexpectedly onto a charged bus, thereby avoiding all casualties or large-area blackout caused by failure of important electrical equipments.
Description
When the utility model relates to a kind of examination and repair for high-pressure switch cubicle, the isolation switch insulation cover of the protection that is used to ensure safety.
In the prior art, maintenance 6～10kv generally is every being placed between the moving contact and fixed contact of isolating switch with insulation barrier during switch cubicle, mechanical distance between this dynamic/static contact is the 150-180 millimetre, go to install just enough difficulties of baffle plate itself at like this little interval, it is again live line working in addition, specification requirement is very high, and is careless slightly with regard to the entail dangers to person and device security.In addition, because the baffle plate heaviness generally is to be hung with insulating bar; in the process of being hung, regular meeting's generation baffle plate drops and wounds people and equipment, because baffle plate placement rear stability is poor; the time swing to charged contact on one side, making moist as baffle plate also to cause three-phase arcing short circuit accident.Therefore, adopt general insulation barrier to exist the problem of casualties and the generation of device damage accident.
The purpose of this utility model provides a kind of safe in utilization, the isolation switch insulation cover that uses when being used to overhaul 6～10KV switch cubicle.
Above-mentioned purpose of the present utility model is to realize by such technical scheme, it is a kind of isolation switch insulation cover, comprise cover body, it is characterized in that: the one side of cover body has and its processing all-in-one-piece angle strutting piece and supporting case, wherein the angle strutting piece is positioned at the below of supporting case, have the hole with the housing axially parallel on it, below the another side of housing, have location notch.
Said structure of the present utility model is further specified by the embodiment that accompanying drawing provides.
The utility model has following accompanying drawing:
Accompanying drawing 1 is a structural front view of the present utility model;
Accompanying drawing 2 is a structure sectional side view of the present utility model;
Accompanying drawing 3 is a structure vertical view of the present utility model.
Referring to accompanying drawing: the isolation switch insulation cover among the figure comprises cover body 1, it is characterized in that: the one side of cover body 1 has and its processing all-in-one-piece angle strutting piece 2 and supporting case 3, wherein angle strutting piece 2 is positioned at the below of supporting case, have the hole 5 with the housing axially parallel on it, below the another side of housing, have location notch 4.In the present embodiment, the front of angle strutting piece 1 has spacing angle or limited impression, and the spacing angle of the angle strutting piece shown in the accompanying drawing 3 is 120 degree.The sectional area of supporting case is a triangle, and its subtended angle position 35 degree are the most suitable.In addition, the surface of housing is a smooth surface.
Use of the present utility model is such: promptly insert supporting case with transformer station's insulating bar commonly used along angle strutting piece 120 degree central angles, arbitrarily be placed on insulating cover on the isolating switch moving contact easily, or pull down from it, in order to adapt to the angle and distance of multiple environment, during this cover of dismounting also available action masthead end penetrate in the hole of angle strutting piece and carry out, because the insufficient light of 6-10KV switch gear room, insulating cover is designed to color red and white, strengthens visual impression on the three-phase moving contact thereby divide to be loaded in.
The insulating properties height that the utility model has owing to described structure, safe and reliable, light and handy nimble Advantage. When inspecting, does the indoor switch cabinet of using it for 6～10KV switching voltage grade safety prevention measure, When the isolating switch accidental fall is to the charged bus, can play the most direct reliable protective action, from Damage the large area blackout that causes and stop all personal injuries and great electric equipment.
