Abstract
The utility model provides a detachable maintenance test unit for a gas insulated metal enclosed switchgear, which comprises a detachable casing and a casing with a hand hole. The detachable casing and the casing with the hand hole are fixedly connected through a bolt and form a barrel body, a basin type insulator is respectively fixed at two ends of the barrel body, and a sealing cavity is formed among the detachable casing, the casing with the hand hole and the two basin type insulators. When a shielding head is respectively installed on the two basin type insulators, the sealing cavity becomes an insulating fracture which has the effects of insulation and isolation during field tests. When a contact is respectively installed on the two basin type insulators, a detachable conductor is mounted between the two contacts and sealed to form a section of a bus of the gas insulated metal enclosed switchgear so as to have the effect of circuit connection. The detachable maintenance test unit for the gas insulated metal enclosed switchgear has various functions of site maintenance, segmented assembly and disassembly and test separation.
Description
[technical field]
The utility model relates to a kind of Cubicle Gas-Insulated Switchgear with dismantled and assembled checking experiment unit.
[background technology]
The scale of application of gas insulated metal sealing switch equipment (GIS) transformer station is increasing at present, owing to the raising of testing equipment finite capacity and field test requirement, often need carry out Insulation Test to the GIS segmentation when testing at the scene.The dismounting function of disintegrating can only be realized in the disintegration dismounting unit of using at present, and complex structure, and manufacturing cost is high.Therefore, be necessary to design a kind of both can be in the segmentation disintegration dismounting of when maintenance, and possess the dismantled and assembled checking experiment unit of testing isolated edge function of time-division at the scene.
[utility model content]
The purpose of the utility model provides a kind of Cubicle Gas-Insulated Switchgear with dismantled and assembled checking experiment unit, to solve the problems of the technologies described above.
To achieve these goals, the utility model adopts following technical scheme:
A kind of Cubicle Gas-Insulated Switchgear comprises detachable housing and band hand hole housing with dismantled and assembled checking experiment unit; Detachable housing is connected through bolt with band hand hole housing, and detachable housing forms a cylindrical shell with band hand hole housing, and these cylindrical shell two ends all are fixed with disc insulator, between detachable housing, band hand hole housing and two disc insulators, form an annular seal space.
Respectively be equipped with one on two disc insulators and test the shielding head.
A contact respectively is installed on two disc insulators, a removable conductor is installed between two contacts.
Removable conductor comprises first conductor, second conductor and connector; Two contacts comprise first contact and second contact; First conductor inserts in first contact, and second conductor inserts in second contact, and first conductor is crossed connector with second conductor dbus and is connected.
Position over against connector on the housing is provided with cover plate.
With respect to prior art, the utlity model has following advantage: the utility model possesses site examining and repairing segmentation dismounting and separates multiple function with test; This unit housings is connected with GIS equipment bus housing, and insulating basin is independent air chamber with the dismounting unit separation, removable conductor access device loop when normal operation, and dismantled and assembled checking experiment unit has flow conductivity and the insulation property identical with the equipment bus.Cubicle Gas-Insulated Switchgear (GIS) is opened the hand hole cover plate of dismounting unit housings when the scene needs Sectional Test, removes removable conductor, and radome is used in installation test, sealing hand hole cover plate.At this moment dismantled and assembled checking experiment unit just becomes a test fracture reliably.Can carry out on-the-spot Insulation Test respectively in both sides.Test is reinstalled removable conductor after accomplishing, and can put into operation after closed cover, the inflation.Break down when need disintegrating maintenance at GIS equipment, open the hand hole cover plate of the dismounting unit housings nearest, remove removable conductor apart from the fault point, remove the dismounting unit housings then after, just can remove faulty equipment.Can recovery be installed according to opposite order after the fault restoration.This dismantled and assembled checking experiment unit also can use when current period equipment and existing equipment butt joint in the engineering enlarging, and method for using is identical with the maintenance assembly and disassembly methods.
The whole parts of the utility model adopt the ripe part of existing Cubicle Gas-Insulated Switchgear (GIS) to combine, and need not increase the part kind.Therefore, the utility model technical maturity, simple in structure, to install easily, flexible arrangement is suitable for factory and produces in batches.
[description of drawings]
Structure cutaway view when accompanying drawing 1 normally moves for the utility model.
Structure cutaway view when accompanying drawing 2 is the utility model Sectional Test.
Among the figure: 1 is disc insulator, and 2 is detachable housing, and 3 are band hand hole housing, and 4 is cover plate, and 5 is removable conductor, and 51 is first conductor, and 52 is second conductor, and 53 is connector, and 6 is contact, and 7 are test shielding head.
[embodiment]
See also shown in Figure 1ly, a kind of Cubicle Gas-Insulated Switchgear of the utility model is with dismantled and assembled checking experiment unit, comprises disc insulator 1, detachable housing 2, band hand hole housing 3, cover plate 4, removable conductor 5, contact 6 and test shielding 7.
Charge into SF6 gas in the utility model normal running (operation) conditions lower house 3, become a metal enclosed gas isolated bus equipment, insert in the GIS product; As shown in Figure 1, the left side connects a GIS equipment 10, and the right side connects the 2nd GIS equipment 20.When the GIS product needed is disintegrated maintenance, open cover plate 4, remove removable conductor 5 (unclamp bolt, lay down connector 53, first conductor 51 and second conductor 52 are pulled up from the contact 6 of correspondence).After conductor 5 was pulled down, compression detachable housing 2 just can be pulled down removable unit.
As shown in Figure 2, when the scene needs Sectional Test, removable conductor 5 is pulled down, change test shielding 7, dismantled and assembled checking experiment unit just becomes a reliable isolation fracture, guarantees that two side apparatus carry out Insulation Test.Test reverts to structure shown in Figure 1 after accomplishing, and can put into operation.
