Description
Technical field
The utility model relates to a kind of high-tension switch cabinet, the mid-withdraw-type switchgear of particularly a kind of armouring.
Background technology
Aborning power plant, power transformation in one's power the switchgear house of industrial and mining enterprises accept all will to use high-tension switch cabinet with distributing electric energy, switch cubicle has been developed polytype product up to now.KYN61 one 40.5 type armored withdraw type metal enclosed switch cabinets as a rule, K wherein represents armouring, and Y represents withdraw-type, and N represents indoor type, and 61 is sequence number, 40.5 expressions of numeral load voltage values.This switch cubicle generally has fixing size, and adopts the welding manner assembling, because the space specification limits also can only be done the adjustment of size among a small circle.
Typical technical scheme can be divided into dynamo-electric instruments and meters chamber, handcart chamber, cable vault and four parts of bus-bar room by functional character.Now most switch cubicle product all is to adopt the welded type cabinet body structure, and presentation quality is also big and the accuracy of manufacture is not high not as assembling cabinet, handcart volume.Because the assembling cabinet has good looking appearance, can improve the quality of fit of handcart and cabinet, production, assembling etc. can both be satisfied user's needs.Need to develop a kind of adopt advanced technical standard and manufacturing process for this reason, adapted novel breaker and element, increase new function, index develops skill, make it reach advanced international level at production, outward appearance and aspect of performance, and make air distance and all bigger, have the big lower product of insulation margin cost along the face creep distance.
The utility model content
The purpose of this utility model is to provide a kind of armouring mid-withdraw-type switchgear, the mid-withdraw-type switchgear of this armouring is through assembling by the dual flanging moulding of aluminizing zinc steel plate, quick and environmental protection are installed, handcart advancing mechanism is positioned at the cabinet chassis and is convenient to safeguard, bus adopts the air insulation mode also to help to improve fail safe.
In order to reach above-mentioned purpose, the utility model adopts following concrete technical scheme: the mid-withdraw-type switchgear of a kind of armouring comprises relay control room, handcart chamber, cable vault and bus-bar room; More than the outside of each chamber be that cabinet supports, separate with metallic plate between each chamber; Whole cabinet is that steel plate compacting bolt assembles; Handcart advancing mechanism is positioned at the cabinet chassis; Adopt the air insulation mode in the bus-bar room.
The utility model beneficial effect mainly shows as: 1, cabinet is that sheet metal bends, and the bolt assembled formation has improved the quality of fit of handcart and cabinet, and good looking appearance can be organized production, assembling and punctual delivery rapidly; 2, handcart is positioned at the cabinet chassis and can makes handcart be locked in the service position reliably by feed screw nut's self-locking performance, prevents the handcart play and accidents caused; 3, bus adopts air insulation, and fail safe improves, and separates with bus casing between adjacent cabinet to prevent effectively that accident from spreading, and plays the supplemental support effect to main bus bar simultaneously; 4, chain mandatory mechanical latching mode, satisfied " five is anti-" function of all adopting between main switch, handcart, earthed switch and the cabinet door.
Description of drawings
Fig. 1 is the structural representation of the mid-withdraw-type switchgear of a kind of armouring of the utility model.
Fig. 2 is the front view of the mid-withdraw-type switchgear of a kind of armouring of the utility model skeleton structure;
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
As shown in Figure 1, the utility model is by the skeleton 1 of peripheric surface, circuit breaker cart 2, and wall bushing 3, contact box 4, dividing plate 5 (wherein contact box 4 is adjacent with dividing plate 5, illustrates together in accompanying drawing 1), earthed switch 7, current transformer 8 and danger spot dividing plate 9 are formed by combining.Wherein wall bushing 3 is set in the outside of cable through walls, is arranged on the cabinet top and enters into switch cubicle by wall.The electric current major loop can adopt exposed bus, also can adopt isolated bus (when adopting isolated bus, alternate and connector is furnished with the insulating case of staying and forming with fire proofing), main bus bar is a sectionalized bus, separate with bus casing between adjacent cabinet, the accident of preventing spreads, and simultaneously main bus bar is played the supplemental support effect.Bus is connected with fixed contact 6, and fixed contact 6 cooperates with the moving contact of circuit breaker cart 2, and circuit breaker cart 2 can move by the feed screw nut propulsive mechanism, and fixed contact 6 also is connected with current transformer 8, is separated with danger spot dividing plate 9 between wherein.
Whole handcart advancing mechanism is positioned on the cabinet chassis, and novel all insulation vacuum circuit-breaker is housed on the handcart, the feed screw nut propulsive mechanism is housed in the handcart vehicle frame, the feed screw nut propulsive mechanism is operated like a cork handcart is moved between disconnection or test position and service position, self-locking performance by feed screw nut can make handcart be locked in the service position reliably, prevents because electrodynamic effect causes the handcart play accidents caused.Interlocking between main switch, handcart, earthed switch and the cabinet door all adopts mandatory mechanical latching mode, satisfies " five is anti-" function.Only when disconnection or test position, circuit breaker just can carry out closing operation to circuit breaker cart 2, and the propulsive mechanism of handcart 2 can't be operated behind breaker closing, meets push-and-pull circuit breaker cart 2 to prevent band.
Have only when earthed switch 7 is in gate-dividing state, circuit breaker cart 2 could move to the service position from disconnection or test position.When earthed switch 7 was in gate-dividing state, cable vault's door can't be opened, and had prevented to be strayed into charged interval.Circuit breaker cart 2 is in test or service position and when not controlling voltage, only can manually separate and can not close a floodgate.Circuit breaker cart 2 is when the service position, and secondary plug is lockable and can not pulls out.
As shown in Figure 2, top of the present utility model is provided with brows 10, is provided with wiring support 11 at the left of instrument box inside door transition door 12, is provided with control room's inside door 13 on its right side.Left plate 14, instrument box inside door 12, wiring support 11 grades all are by screw and screw sky 23 incompatible the interfixing that match, and are provided with valve guide rail 15 in the centre of cabinet, the right side is provided with bent plate 16 and right guide rail mounting panel 8 behind the bus-bar room, and these parts also all are connected and fixed by screw.From left to right be disposed with left connecting rod mounting panel 22 in the bottom of cabinet, left rail mounting panel 21 its belows are middle lower clapboard shrouding 20; Wire casing 19 and lamp bracket 18 are arranged in the bottom on cabinet right side.
