Abstract

The utility model relates to movable type alternating current metal sealed switch equipment, comprising a handcart chamber, a bus chamber, a cable chamber and a low-voltage chamber, wherein three-phase main buses and three-phase branch buses are arranged in the bus chamber; the three-phase main buses are respectively connected with the three-phase branch buses, and arranged from top to bottom; and the three-phase branch buses are staggered in a front and back way. Compared with the background art, the utility model has the advantages of uniform distribution of electric field, enhancement of voltage-resistance level and integral insulation level, enhancement of safety property, compact structure, little space occupation and good insulating property.

Description

The AC metal closed type switchgear of withdraw-type
Technical field
The utility model relates to the AC metal closed type switchgear of a kind of withdraw-type.
Background technology
Withdraw type metal enclosed switchgear, it includes handcart chamber, bus-bar room, cable vault and low-pressure chamber.Three-phase main bus bar and three-phase branch bar are set in this bus-bar room, and this three-phase main bus bar connects the three-phase branch bar respectively.As the utility model of Chinese patent database at the ZL 200420090454 of on January 4th, 2006 bulletin, its denomination of invention is " the bus-bar room structure of metal armouring draw out switchgear cabinet ".Or as the utility model of Chinese patent database at the ZL2006200891331 of on January 24th, 2007 bulletin, its denomination of invention is " the indoor AC metal closed switch cabinet of armored withdraw type ".This three-phase main bus bar vertically is provided with and is arranged in order from top to bottom, and this three-phase branch bar is between left and right every also " one " word arrangement.Because therefore this three-phase branch bar " one " word arrangement has following deficiency: one, non-uniform electric, withstand voltage level, insulation level are not high; Its two, in order to improve security performance, need to increase spacing distance, increase bus-bar room and take up room.
The utility model content
The purpose of this utility model provides the AC metal closed type switchgear of withdraw-type, and it has overcome the problem that the existing withstand voltage level in the AC metal closed type switchgear of existing withdraw-type median generatrix chamber is not high, insulation level is not high, bus-bar room takes up room big deficiency.
The technical scheme that its technical problem that solves the utility model adopts is:
The AC metal closed type switchgear of withdraw-type, it includes handcart chamber, bus-bar room, cable vault and low-pressure chamber, three-phase main bus bar and three-phase branch bar are set in this bus-bar room, this three-phase main bus bar connects the three-phase branch bar respectively, this three-phase main bus bar is arranged in order from top to bottom, is staggeredly arranged before and after this three-phase branch bar.
In the preferred embodiment of the present utility model, this three-phase main bus bar is vertically evenly distributed successively from top to bottom.
In the preferred embodiment of the present utility model, this main bus bar is single-phase to be obliquely installed up and down.
The AC metal closed type switchgear of the utility model withdraw-type is compared with background technology: owing to be staggeredly arranged before and after the three-phase branch bar in its bus-bar room, therefore overcome the existing deficiency of background technology, and has a following advantage: one, Electric Field Distribution is even, withstand voltage level, integral insulation level improve, and security performance improves; Its two, compact conformation, little, good insulation preformance takes up room; Its three, can with the AMS-10kV switchgear directly and cabinet.Because angle is 30 degree between main bus bar and the horizontal plane, the arranged of main bus bar and branch bar is even, the electrical distance maximum reasonableization, and Electric Field Distribution is even.Three-phase branch bar angle of inclination is identical with the main bus bar angle of inclination, and Electric Field Distribution is even.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic perspective view of the present utility model.
Fig. 2 is the schematic diagram of the utility model median generatrix chamber.
Embodiment
Please refer to Fig. 1 and Fig. 2, a kind of cabinet is wide to be 325 millimeters the indoor ac metal closing switch gear of armored withdraw type, particularly AFC (7.2KV, 400A, 25kA) advance, feeder line contactor cabinet, it includes handcart chamber A, bus-bar room B, the C of cable vault and low-pressure chamber D.Three-phase main bus bar 10 and three-phase branch bar 20 are set in this bus-bar room B, and this three-phase main bus bar 10 is electrically connected three-phase branch bar 20 respectively.Fixed contact in this three-phase branch bar 20 and the Chinese character pin-shaped contact box is electrically connected mutually.
This three-phase main bus bar 10 is parallel and vertically evenly distributed successively from top to bottom, and each main bus bar 10 all is obliquely installed up and down, and angle is 30 degree between it and the horizontal plane.These three-phase branch bar 20 front and back are arranged about staggering also.
