Description
Technical field
The utility model belongs to switchgear control technology field, particularly a kind of GIS casing seat.
Background technology
GIS is that the English of gas-insulating and fully-enclosed combined electrical apparatus is called for short.GIS is made up of circuit breaker, isolating switch, earthed switch, instrument transformer, lightning arrester, bus, connector and outlet terminal etc., these equipment or parts are all enclosed in the shell of metal ground connection, be filled with the SF6 insulating gas of certain pressure therein, therefore also claim SF6 fully closed combined electric unit.126KvGIS equipment is maked somebody a mere figurehead line mode complexity, and form is various.Most often the form of bus adapter sleeve base through walls line, and under this kind of form, reasonably solves the conduit connection end problem solving that necessitates of the balance between clear distance and manufacturing cost over the ground.And meeting under the precondition that allows lightning impulse field intensity value, in limited Threephase common-box casing seat inner space, shape and trend how to arrange inner three-phase conductor properly also become key problem.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and a kind of conduit connection end is provided, and clear distance is relatively large over the ground, simple for structure, the GIS casing seat of the Threephase common-box casing seat that manufacturing cost is lower.
For this reason, the technical solution of the utility model is: a kind of GIS casing seat, is characterized in that: it comprises casing seat housing, disk insulator, three-phase conductor, guide post, spring touch finger and junction block; Described casing seat housing is hollow-core construction, and top has three cylinder open arranged side by side, and middle cylinder open direction is vertical with the bottom surface of casing seat housing; Three-phase sleeve pipe is installed at three cylinder open places of described casing seat housing top, and described three-phase sleeve pipe is built-in with sleeve pipe conductor, and bottom has endoporus; On described disk insulator, there is three-phase link; Described disk insulator is fixed on the bottom of casing seat housing, with the common formation of casing seat housing one air chamber; Described three-phase conductor is placed in air chamber, is made up of the A phase conductor, B phase conductor and the C phase conductor that are column structure, corresponds respectively to A phase, B phase and the C phase of alternating current; Described A phase conductor, B phase conductor and C phase conductor are triangularly arranged; Described A phase conductor, C phase conductor top are respectively toward the outer side; Described B phase conductor top orientation is vertical with disk insulator; Described three-phase conductor bottom respectively with disk insulator on three-phase link suitable; Described three-phase conductor top has screwed hole; Described junction block lower end has external screw thread, screws up with the internal thread of three-phase conductor top screwed hole; Described junction block upper end is hollow cylinder structure, and internal side wall is equipped with spring touch finger; Described guide post one end is through junction block and three-phase conductor, and the cylindrical of the other end matches with the endoporus of sleeve pipe conductor bottom; Described sleeve pipe conductor bottom is placed in junction block, touches mutually with spring touch finger.
When the utility model work, under the built on stilts line condition of 126KvGIS, after bus is through walls, connect disk insulator and casing seat housing by flange; Three-phase sleeve pipe is fixed by flange and casing seat housing respectively accordingly.After installation, three-phase sleeve pipe is fork-shaped arranged side by side and distributes, and B phase moves towards parallel with GIS bus, make three-phase conduit connection end over the ground clear distance relatively strengthen.Under this kind of form, can save GIS bus and use, reduce enterprise's manufacturing cost.The utility model, under the empty line condition of GIS bus joint sleeve mounting through walls, has been optimized casing seat line form, adopts three-phase fork-shaped arranged side by side to distribute, and B phase moves towards parallel with GIS bus, has increased conduit connection end clear distance over the ground.This casing seat internal structure is simply compact simultaneously, and conductor connects safe and reliable, manufacturing cost relatively economical.Increasing conduit connection end over the ground in clear distance, the saving that is also conducive to GIS bus is used.
