Abstract
The utility model discloses a bus chamber of removing-type metal closed switching equipment, which is arranged in armor removing-type indoor alternating current metal closed switching equipment. Three-phase main buses and three-phase branch buses are arranged in the bus chamber, wherein, the three-phase main buses are respectively connected with the three-phase branch buses, the three-phase main buses are arranged from top to bottom in sequence, and the three-phase branch buses are stagger from the front part to the rear part. Because the three-phase branch buses in the bus chamber are arranged from top to bottom in sequence, the bus chamber has the following advantages: firstly, the electric field distribution is uniform, the voltage withstand level and the overall insulating level are enhanced, and the safety performance is improved; secondly, the structure is compact, the occupied space is small, and the insulating property is good; and thirdly, the bus chamber can be directly combined with the AMS-10kV switching equipment.
Description
Technical field
The utility model relates to a kind of bus-bar room of withdraw type metal enclosed switchgear.
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 a kind of bus-bar room of withdraw type metal enclosed switchgear, and it has overcome, and the existing withstand voltage level of background technology bus-bar room 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:
A kind of bus-bar room of withdraw type metal enclosed switchgear, it is arranged in the indoor ac metal closing switch gear of armored withdraw type, 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 three-phase main bus bar is arranged in parallel.
In the preferred embodiment of the present utility model, this main bus bar is single-phase to be obliquely installed up and down.
In the preferred embodiment of the present utility model, angle is 30 degree between this main bus bar and the horizontal plane.
In the preferred embodiment of the present utility model, this three-phase branch bar is provided with about also.
The technical program is compared with background technology: owing to be staggeredly arranged before and after the three-phase branch bar in the bus-bar room, therefore overcome the existing deficiency of background technology, and had 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 has illustrated a preferred embodiment switchgear schematic perspective view.
Fig. 2 has illustrated the schematic diagram of the bus-bar room of a preferred embodiment switchgear.
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.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
