Abstract
The present invention provides a dry type capacitive short tail type GIS sleeve aiming at the problems that a conventional dry type high voltage GIS sleeve is severe in material loss, long in production cycle and very low in universality and versatility. The dry type capacitive short tail type GIS sleeve of the present invention comprises a conductive rod, a sleeve core body arranged outside the conductive rod, a voltage-sharing sealing cover and a sleeve flange, and an umbrella skirt structure is arranged outside the sleeve core body. The dry type capacitive short tail type GIS sleeve is characterized in that a set of inverted capacitive screens are arranged inside the sleeve core body and are located between the voltage-sharing sealing cover and the sleeve flange, and the core body at the lower end of the flange is a 2 to 4-step stepped shape. The dry type capacitive short tail type GIS sleeve of the present invention enables the weight to be reduced, is suitable for the narrow space installation, saves the production materials, is short in production cycle and strong in versatility, and is convenient to install.
Description
technical field:
The present invention relates to a kind of dry-type capacitance type short-tail formula GIS sleeve pipe, belong to electric sleeve kit equipment technical field.
background technology:
Dry-type high-voltage GIS(traditional at present and Cubicle Gas-Insulated Switchgear) sleeve pipe afterbody insulation system is for ensureing core body internal electric performance, add the length in oil or in gas accordingly, this just makes tail length larger, also result in simultaneously and installs the larger space of GIS sleeve pipe needs.Because traditional dry-type high-voltage GIS sleeve pipe afterbody is long, casing wt strains greatly mutually, and the metal shell matched with it will increased in size, meets supporting sleeve weight and installing space, and metal shell must and sleeve kit.Traditional dry-type high-voltage GIS shell material loss is serious, the production cycle long, general, versatility is extremely low.
summary of the invention:
The object of the invention is to provide a kind of dry-type capacitance type short-tail formula GIS sleeve pipe for above-mentioned Problems existing, can casing wt be alleviated, adapt to small space installation, save production material, with short production cycle, versatility strong, install facility.
Above-mentioned object is realized by following technical scheme:
Dry-type capacitance type short-tail formula GIS sleeve pipe, comprise conducting rod, be arranged on the sleeve pipe core body of conducting rod outside and all densification capping and casing flange, described sleeving core external body is provided with umbrella skirt construction, inverted layout one group of capacitance plate is adopted inside described sleeve pipe core body, described capacitance plate is arranged on inside described sleeve pipe core body between equal densification capping and casing flange, and the core body of described flange lower end is the step-like of 1-4 level.
Described dry-type capacitance type short-tail formula GIS sleeve pipe, described sleeve pipe afterbody is provided with voltage equalizing ball.
Described dry-type capacitance type short-tail formula GIS sleeve pipe, described casing flange is provided with measurement terminal.
Described dry-type capacitance type short-tail formula GIS sleeve pipe, is provided with O-ring seals between described equal densification capping and described conducting rod.
Beneficial effect:
Internal capacitance screen of the present invention adopts inverted method to lay.The flange lower end of GIS sleeve pipe is exactly afterbody, and afterbody core body does not have capacitance plate, and length reduces greatly.Afterbody core body is when machining, and the step of car some, meets creep distance requirement.Sleeve pipe afterbody shortens, can realize multiplex, adapt to small space install, reach casing wt light, with short production cycle, save produce material, multiduty object, on the basis ensureing dry-type high-voltage GIS casing property, make sleeve pipe weight reduction, adapt to small space installation, save production material, with short production cycle, versatility strong, install facility.
accompanying drawing illustrates:
Fig. 1 is cross-sectional view of the present invention.
