Abstract
The utility model relates to an outdoor dry switch casing pipe, which is mainly composed of a casing pipe body, a current carrier, terminals, a flange, an umbrella skirt and a rain cover, wherein, the casing pipe body adopts an able through type structure; the current carrier penetrates through the casing pipe body, and both ends of the current carrier are the terminals; the flange is arranged at the middle part of the casing pipe body; the umbrella skirt is made of silicon rubber composite material. The utility model has the advantages of no oil, no porcelain, light structure, uniform voltage distribution on the surface and in the radical direction, fire retardation, explosion protection, natural anti-dirt property, natural aging-resistant property, and natural anti-electrical carbon trace property, can be used as a switch sleeve pipe of vacuum circuit breakers or other oilless circuit-breakers and can also be used as a penetration sleeve pipe or a current mutual inductor in transformer substations and power plants.
Description
Along with the development of domestic and international electric utility, high voltage electric appliance is progressively to no oiling, non-vitrification development.Because of being subjected to its " insulator ", " oil-filled " structural limitations, there are problems such as easy ageing of insulation, oil impregnate, leakage of oil, heating burst in the employed DW series 35KV of domestic transformer station heavy wool switch, and need in service are made regular preventive trial.Relevant producer substitutes oil switch with the 35KV vacuum packet, and because of it has continued to use the porcelain bushing of oil switch, technical performance index is influenced by it still, anti-pollution flashover ability, and the volume heaviness, insulator easily breaks, and transportation is installed inconvenient, and spread voltage is inhomogeneous or the like.
The purpose of this utility model is to provide a kind of outdoor dry type switch sleeve pipe that does not have the no porcelain of oil.
The technical solution of the utility model is: it is made of union body, carrying object, terminals, flange, full skirt and rain cover; Union body adopts four layers and wears cable formula structure, and outermost layer is the silicon rubber composite insulation layer, and the second layer is the capacitor voltage equalizing screen, and the 3rd layer is dielectric isolation layer, and innermost layer is a metal sleeve; Flange is fixed on the union body middle part, on the union body of flange one end full skirt is housed; Capacitor voltage equalizing screen end screen lead-in wire is fixed on the flange; The union body two ends are provided with metal and all press rain cover; Carrying object is through union body, and two ends have terminals.
Full skirt of the present utility model adopts the silicon rubber composite insulating material.
The utility model does not have the no porcelain of oil, and structure is light and handy, and surface and diametral voltage are evenly distributed, and flame-proof explosion-proof is non-maintaining, and has dirty, the anti-aging and anti-electric charcoal trace performance of natural anti-soil.It also can be used for transformer station, the 35KV wall bushing is made in the power plant or current transformer uses except that the switch sleeve pipe as 35KV vacuum circuit-breaker or other oil-less circuit-breaker.
Accompanying drawing 1 is the utility model structural representation.
Below in conjunction with most preferred embodiment of description of drawings.
The utility model is made up of union body 9, carrying object 5, terminals 11, flange 6, full skirt 8 and rain cover 10; Union body adopts and wears cable formula structure, has four layers, and outermost layer is a silicon rubber composite insulation layer 1, and the second layer is that the capacitor voltage equalizing screen is that dielectric isolation layer is a metal sleeve 4 for 3, the four layers for 2, the three layers.Flange 6 is fixed on the middle part of union body, and the end screen lead-in wire 7 of capacitor voltage equalizing screen is fixed on the flange, on the union body of the right-hand member of flange the full skirt made from the silicon rubber composite insulating material 8 is installed, and can be used as outdoor end.Fixing metal is all pressed rain cover 10 at the two ends of union body.Carrying object 5 is in the metal sleeve of union body, and union body is stretched out at two ends, by bolt terminals 11 is installed at the two ends of carrying object.
Claims (2)
