Background technology
At present in solid insulation ring main unit, often need to concentrate in a unified seal to vacuum switch, earthed switch and isolating switch and install, such seal product of market is roughly divided into three kinds, the first: three-phase one Room gas-filled type two position operation, constructure design, B, C three-phase coexist the insulation of insulating resin indoor gas, and drawback 1. such as a whole vapour case room of duty of breaking down is scrapped.2. as leaked gas then, three phase isolated distance is accidents caused not.3. vacuum switch operating position.Do not have excessive position in the middle of isolation, earthed switch operating position, it is accidents caused that the direct ground connection of isolating switch easily produces electric arc damage contact.Domestic related switch expert has emphasized to install an excessive position additional between isolation, ground connection.Separately use about SF6 and the clear stipulaties minimizing of other gas world, this product cannot meet related request.The second: be single-phase two Room two position operation not inflatable body.Constructure design, B, C three-phase insulation resin cylinder independently separate every two operating positions mutually.Vacuum switch operating position, drawback is isolated equally, earthed switch operating position is middle does not have excessive position, and it is accidents caused that the direct ground connection of isolating switch easily produces electric arc damage contact.This product cannot meet concerned countries requirement.The third: three cell structure design A, B, C three-phase insulation resin cylinders are independently separately.Vacuum switch independent operation room, earthed switch independent operation room.Isolating switch independent operation room, takes vacuum bubbles to divide, closes isolating switch.Drawback can not meet the relevant isolating switch visible observation requirement of country.Existing market same equipment outlet insulating cylinder Basic Design before bottom in after arrangement, need remove equipment when plant maintenance, maintenance, under hauling out the dismounting of outer cabinet, shrouding is lifted to certain altitude and can keeps in repair.Separately there is partial design at top, need equipment be removed when plant maintenance, maintenance equally, haul out outer cabinet dismounting upper sealing plate and keep in repair.Word order rubber bus is converted to upper, middle and lower above to also have partial design, and the too much resistance of contact is large, and installing space is little, and bus mould is complicated.For above deficiency, in the urgent need to developing a kind of brand-new seal.
Utility model content
For the deficiency that prior art exists, the utility model provides a kind of single-phase three Room three position operation independence resin insulating cylinders, this new structure advantages of simple, bus structure is simple, there is good visuality, safe to use, independent operating performance is good, maintain and replace parts are easy, local damage does not affect Whole Equipment serviceability, thus greatly improves the useful life of equipment, and without the need to equipment is removed in power distribution cabinet during maintenance, greatly improve its overhaul efficiency, contribute to the stability and the continuity that improve solid insulation ring main unit operation.
To achieve these goals, the utility model realizes by the following technical solutions:
A kind of single-phase three Room three position operation independence resin insulating cylinders, it is characterized in that: it comprises three arranged in parallel and separate insulation resin cylinder, uniform eight insulating cylinders in described insulation resin cylinder upper surface fix swivel nut, fix swivel nut by insulating cylinder between described insulation resin cylinder to be connected with upper mounted plate, separately vacuum interrupter chamber is established in described insulation resin cylinder, earthing switch room and isolating switch room, and vacuum interrupter chamber, earthing switch room and isolating switch room separate, described vacuum interrupter chamber, earthing switch room and isolating switch room are all at least provided with eight covers and fix swivel nut, described isolating switch room one side surface is inlet wire side, described earthing switch room one side surface is outgoing line side, and inlet wire side and outgoing line side are parallel to each other, described inlet wire side and outgoing line side are all vertical with insulation resin cylinder upper surface, entrance bushing and inspection hole are established in described inlet wire side, described outgoing line side sets out thread casing and finger-contact type grounding contact, wherein entrance bushing is connected with vacuum interrupter chamber top, described outlet casing tube is connected with vacuum interrupter chamber bottom, entrance bushing on three described insulation resin cylinders, inspection hole and finger-contact type grounding contact are distributed in the same rectilinear direction parallel with insulation resin cylinder upper surface.
Further, full skirt anti-tracking structure is separately established in described isolation, earthed switch chamber interior walls.
Further, outlet casing tube is distributed in insulation resin cylinder upper surface is in the same rectilinear direction of 10 ° of-60 ° of angles.
This new structure advantages of simple, bus structure is simple, have good visuality, safe to use, independent operating performance is good, maintain and replace parts are easy, local damage does not affect Whole Equipment serviceability, thus greatly improves the useful life of equipment, and without the need to equipment is removed in power distribution cabinet during maintenance, greatly improve its overhaul efficiency, contribute to the stability and the continuity that improve solid insulation ring main unit operation.
