Abstract

The utility model belongs to electric types and relates to a combined box substation provided with a transformer chassis truck. The combined box substation is suitable for being used by power supply, power transformation and power distribution systems, and mainly comprises a box body, a high-voltage switch device, a transformer and a low-voltage power distribution device. A cavity inside the box is divided into a high-voltage chamber, a transformer chamber and a low-voltage chamber; a closed division plate is arranged between each two chambers; and a low-voltage main circuit breaker of the low-voltage chamber is connected with the high-voltage switch device of the high-voltage chamber through the transformer of the transformer chamber. One chassis truck is arranged at the bottom portion of the transformer of the combined box substation, and a rail is erected on a base of the transformer chamber. When the box substation is assembled, firstly, the transformer is fixed onto a chassis; secondly, the chassis truck is fixedly connected with the rail; and the transformer is connected with a high-voltage control cabinet and a low-voltage control cabinet. The combined box substation has the advantages of being capable of conveniently moving the transformer out of the box body of the box substation through manpower without the aid of engineering machinery such as a hoist and the like, conducting work for the transformer such as replacement, repair, maintenance and the like, and having reasonable structure, simple and convenient processing, small occupied space and the like.

Description

The composite type cabinet type transformer substation of being furnished with transformer chassis car

Technical field

The utility model relates to electric information, particularly a kind of composite type cabinet type transformer substation of being furnished with transformer chassis car, the composite type cabinet type transformer substation of being furnished with transformer chassis car that refer to especially to be suitable for to power, power transformation or distribution system is used.

Background technology

Box-type substation is because of its compact conformation, little, the relatively low application that gets more and more widely of construction cost of floor space.At present, the box-type substation in producing, using is made up of box for box-type transformer substation, high voltage switchgear, transformer and low-voltage distribution equipment substantially, and all electric equipments are installed in case and become on the base.The box house die cavity is separated into hyperbaric chamber, transformer room, low-pressure chamber, and the dividing plate of sealing is arranged between each chamber, and the low pressure main circuit breaker of low-pressure chamber is connected with the high voltage switchgear in hyperbaric chamber by the transformer of transformer room.But in the present existing box-type substation product, most of transformers are directly by on the base that is bolted to box-type substation, its shortcoming is: when changing or during repair and maintenance transformer, there is very inconvenient situation, such as the top cover of box-type substation when non-dismountable, even if engineering machinery such as crane are arranged, also be difficult to transformer is shifted out box-type substation, and for example because of being subjected to factors such as work-yard restriction, and can't normally use engineering machinery such as crane that transformer is shifted out box for box-type transformer substation etc., moreover engineering machinery such as use crane will certainly increase the maintenance cost of box-type substation again.

The utility model content

It is a kind of rational in infrastructure that the purpose of this utility model is to provide, it is little to take up room, process easy, the composite type cabinet type transformer substation of being convenient to produce in batches of being furnished with transformer chassis car, the transformer bottom is furnished with a chassis car, on transformer room's base, set up track, solve exist in the existing box-type substation if not by engineering machinery such as crane or even engineering machinery such as crane is arranged, but also non-dismountable or because of the restricted and very difficult difficult problem that transformer is shifted out from box-type substation inside in operation place, and help reducing the repair and maintenance cost of box-type substation because of the top cover of box-type substation.

A kind of composite type cabinet type transformer substation, mainly form by casing, high voltage switchgear, transformer and low-voltage distribution equipment, the box house die cavity is separated into hyperbaric chamber, transformer room, low-pressure chamber, the dividing plate that sealing is arranged between each chamber, the low pressure main circuit breaker of low-pressure chamber is connected with the high voltage control cabinet in hyperbaric chamber by the transformer of transformer room.

The transformer bottom is furnished with a chassis car, on transformer room's base, set up track, the chassis car is placed in orbit, when the assembling box-type substation, earlier transformer is fixed on the car of chassis, again chassis car and track is connected and fixed, carry out being connected between transformer and the high and low pressure control cubicle afterwards again, transformer is changed or during repair and maintenance, transformer can be shifted out or moves into box for box-type transformer substation by the motion in orbit of chassis car.

Compared with prior art, the utility model has the advantages that: not by engineering machinery such as cranes, can eaily transformer be shifted out the casing of box-type substation by manpower, carry out the work such as replacing, maintenance, maintenance of transformer, be particularly useful for non-dismountable or can't use engineering machinery such as crane transformer to be shifted out the occasion of box for box-type transformer substation because of factors such as operation place restrictions because of the box-type substation top cover.The arrangement of box-type substation can be " order " font, " product " font, also can be two " order " fonts and two " product " font, has characteristics such as rational in infrastructure, that processing is easy, it is little to take up room, use is flexible.

Embodiment

The utility model is further described below in conjunction with accompanying drawing 1 to 6.

Shown in accompanying drawing 1,2, the transformer bottom is furnished with a chassis car (5), on transformer room's base (6), set up track (4), chassis car (5) is placed on the track (4), when the assembling box-type substation, earlier transformer (2) is fixed on the chassis car (5) with high-strength bolt (3), be connected and fixed with being connected gusset (9) and high-strength bolt (9) and (10) between chassis car (5) and the track (4) again, carry out being electrically connected between transformer (2) and high voltage switchgear, the low-voltage distribution equipment afterwards again.The upper surface of track (4) will guarantee not have obstacle a little more than transformer room's threshold (8) when releasing transformer (2).

Shown in accompanying

drawing

3,4, transformer chassis car (5) is equipped with 4 steamboats (7), fixes with welding manner between wheel shaft and the car body, and shaped steel such as the automobile-used channel-section steel in chassis, angle steel or rectangular steel pipe process, on car body, bore fixing hole, in order to fixing of transformer according to the actual lower margin hole dimension of transformer.

Shown in accompanying

drawing

5,6, be welded with spacing steel plate (12) in the both sides of track (4), prevent chassis car (5) derailing.

After box-type substation puts into operation, when the needs maintenance, when safeguarding, earlier with between transformer (2) and high voltage switchgear, the low-voltage distribution equipment be electrically connected dismounting after, dismantle connecting bolt (10,11) again, the last contour slow ramp of an end and transformer room's inner orbit of setting up in the box-type substation outside, so just the motion of chassis car (5) on track (4) can be passed through, only just transformer (2) box for box-type transformer substation can be shifted out with manpower.
