Abstract
The invention discloses gas-insulated vacuum switch equipment, which comprises a gas tank (1), wherein the gas tank (1) internally comprises a main bus (4), an isolating switch (5) and a vacuum extinction chamber (6); the main bus (4) is arranged horizontally; two ends of the main bus (4) are connected with bus connectors (7) on two sides of the gas tank (1); a static contact cutter (8) is also welded on the main bus (4); the isolating switch (5) is arranged under the static contact cutter (8); and under the isolating switch (5), the vacuum extinction chamber (6) is vertically arranged on the gas tank (1). According to the invention, the main bus (4), the three-station isolating switch (5) and the vacuum extinction chamber (6) are arranged in the gas tank (1) filled with insulated gase, so that the insulating property is improved, the electric clearance is reduced, the size of a cabinet body is greatly reduced, the occupied area is reduced, the influence of external environment climate is reduced simultaneously, and the normal operation under a rugged weather condition is ensured.
Description
Technical field
The present invention relates to a kind of medium voltage switchgear equipment, the switchgear that specifically a kind of gas-insulated vacuum is cut-off.
Background technology
Conventional at present switchgear people adopts air insulation, compound inslation more, and its shortcoming is that electric clearance is bigger, causes the cabinet volume bigger, and floor space is big.In addition, whole switching system is not completely enclosed within the casing of a sealing, receives the restriction of external environment, under the rugged environment weather conditions, is difficult to guarantee equipment safety operation.
Summary of the invention
Technical problem to be solved by this invention provides that a kind of gap is little, volume is little, good insulation preformance, the switchgear that the gas-insulated vacuum that under any climatic environment, can both normally move is cut-off.
In order to solve above-mentioned technical problem; Technical scheme of the present invention is: a kind of gas-insulated vacuum switchgear; Comprise gas tank, comprise main bus bar, isolating switch and vacuum interrupter in the said gas tank, said main bus bar level is installed; The two ends of main bus bar are connected with the bus tie of gas tank both sides, also are welded with quiescent contacting knife on the said main bus bar; Isolating switch is installed below quiescent contacting knife, and below isolating switch, vacuum interrupter is vertically mounted on the gas tank through insulating support, between the said vacuum interrupter insulating barrier is installed.
The width of said gas-insulated vacuum switchgear is 600mm.
Main bus bar of the present invention, tri-station isolating switch, vacuum interrupter are all in insulation gas filled gas tank; Improve insulation property; Reduce electric clearance, thereby cabinet is dwindled greatly, reduced floor space; Simultaneously also reduced the external environment climatic influences, guaranteeing still can operate as normal under the harsh climate condition.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
Fig. 1 is a front view of the present invention.
Fig. 2 is an end view of the present invention.
Embodiment
Like Fig. 1, shown in Figure 2, the width of gas-insulated vacuum switchgear is 600mm, comprises gas tank 1, cable vault 2 and control room 3, and said control room 3 is installed in the front portion of gas tank 1, and cable vault 2 is installed in the bottom of gas tank 1.
Comprise main bus bar 4, isolating switch 5 and vacuum interrupter 6 in the said gas tank 1, said main bus bar 4 levels are installed, and the two ends of main bus bar 4 are connected with the bus tie 7 of gas tank 1 both sides, also are welded with quiescent contacting knife 8 on the said main bus bar 4.
Isolating switch 5 is installed below quiescent contacting knife 8, and the swivelling tool-holder 9 of said isolating switch 5 is installed in the top of gas tank 1, and the one of which end is connected with gas tank 1 by the rotating shaft 10 of sealing, is connected with three station manipulation mechanisms.The grounding contact 11 of isolating switch 5, movable touch knife 12 are installed in left side, the right side of gas tank 1 respectively, and contact knife seat 13 is installed below movable touch knife 12, and grounding contact 11, movable touch knife 12 are installed on the insulator 14 of gas tank 1.
Below isolating switch 5, vacuum interrupter 6 is vertically mounted on the gas tank 1 through insulating support 15, and insulating support 15 is installed on the crossbeam of gas tank 1.Between the said vacuum interrupter 6 insulating barrier 17 is installed.Vacuum interrupter 6 moving conductive rods 18 are connected with seal shaft through set square, and the other end of the seal shaft circuit breaker operation mechanism outer with being positioned at gas tank is connected.
The foregoing description does not limit the present invention in any way, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in protection scope of the present invention.
Claims (2)
1. gas-insulated vacuum switchgear; Comprise gas tank (1); It is characterized in that: comprise main bus bar (4), isolating switch (5) and vacuum interrupter (6) in the said gas tank (1); Said main bus bar (4) level is installed, and the two ends of main bus bar (4) are connected with the bus tie (7) of gas tank (1) both sides, also are welded with quiescent contacting knife (8) on the said main bus bar (4); In quiescent contacting knife (8) below isolating switch (5) is installed, the below in isolating switch (5), vacuum interrupter (6) is vertically mounted on the gas tank (1) through insulating support (15), and insulating barrier (17) is installed between the said vacuum interrupter (6).
2. gas-insulated vacuum switchgear according to claim 1 is characterized in that: the width of said gas-insulated vacuum switchgear is 600mm.
