Abstract
The utility model discloses a busbar bushing used for indoor remove type metal armoring switch gear, which is characterized in that: an equalizing ring (3) is poured in a body (2) of the bushing; the equalizing ring (3) is connected with an insert (1) using a conductor; double layer insulation wall is adopted at the inner side of the body (2) of the busing; certain gap exists between the inner insulation wall (4) and the outer insulation wall. The busbar bushing has the advantages of timely discharging electro-static existed in the busbar bushing, evenly distributing ambient electric field and also increasing creepage distance when the bus is electrified.
Description
Technical field
The utility model relates to a kind of bus casing of electrical power distribution system switchgear, and is especially relevant with the bus casing structure of the indoor metal armoring withdraw-type switchgear of 35kV and following electric pressure.
Background technology
Bus casing is the components and parts of switchgear in indispensability in the contact, because bus casing is the element that bus passes, when switchgear is worked, just have Electric Field Distribution around the bus casing, and along with the rising of electric pressure, the insulation distance that needs is also big more, and this just needs bigger creepage distance.Existing bus casing in use, non-uniform electric around it, and creepage distance can not satisfy the needs of voltage levels.
Summary of the invention
It is even that the purpose of this utility model is designed a kind of Electric Field Distribution exactly, the bus casing that creepage distance is big.
The technical solution of the utility model is: be cast with grading ring in the bus casing, the built-in electrical insulation wall adopts double-decker.
The bus casing that the utility model provides, Electric Field Distribution on every side is even, has strengthened the creepage distance between bus and the mounting panel.
Description of drawings
Fig. 1 is the structural representation of existing bus casing;
Fig. 2 is the structural representation of an embodiment of the utility model bus casing.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, inserts 2, sleeve body 3, grading ring 4, interior insulation wall
As shown in Figure 2, the utility model bus casing is cast with a grading ring 3 in sleeve body 2, and grading ring 3 has lead to link to each other with inserts 1, the inboard double hyer insulation wall that adopts of sleeve pipe, and interior insulation wall 4 is gapped with the external insulation wall, has increased creepage distance.
During use, inserts 1 is fixed on the metal partion (metp), makes its contact good, thereby guarantee that static in time discharges with bolt.
Claims (1)
- A kind of indoor metal armoring withdraw-type switchgear bus casing, comprise sleeve body (2) and inserts (1), it is characterized in that: be cast with a grading ring (3) in the sleeve body (2), grading ring (3) has lead to link to each other with inserts (1), the inboard double hyer insulation wall that adopts of sleeve body (2), interior insulation wall (4) is gapped with the external insulation wall.
