Abstract

The utility model discloses a miniature box type transformer substation which comprises a box body, the box body is divided into a high-voltage chamber, a transformer chamber and a low-voltage chamber from left to right by first to fourth partition plates (1), (2), (3) and (4) sequentially arranged horizontally, a high-voltage circuit breaker (5) is arranged in the high-voltage chamber, a low-voltage circuit breaker (6) is arranged in the low-voltage chamber, a transformer (7) is arranged in the transformer chamber, the high-voltage circuit breaker (5) and the low-voltage circuit breaker (6) are respectively fixed on two sides of the second partition (3), and a wall bushing convenient for connecting cables of the high-voltage circuit breaker (5) and the transformer (7) to penetrate is further arranged on the second partition (2). The miniature box type transformer substation is neat in line connection, low in manufacturing cost and small in occupied space. The miniature box type transformer substation belongs to the field of intelligent power distribution technology.

Description

Miniature box-type substation

Technical field

The utility model belongs to the intelligent power distribution technical field, especially relates to a kind of miniature box-type substation.

Background technology

At present conventional box-type substation is about to transformer, switch, relaying protection and makes separately, in use by the own aggregate erection of equipment applying unit to constituting distribution system together, the transmission and the distribution of completion electric energy.Existing box-type substation is divided into hyperbaric chamber, transformer room and low-pressure chamber from left to right; Be provided with primary cut-out in the described hyperbaric chamber; Be provided with low-voltage circuit breaker in the low-pressure chamber; Primary cut-out and low-voltage circuit breaker be separately fixed at hyperbaric chamber and low-pressure chamber in, and high and low voltage chamber makes respectively separately, arrives with the bolt assembly unit with the transformer room before using.Primary cut-out and the stube cable between the transformer in this transformer station are got around from the transformer top, connect trouble, and how mixed and disorderly line is.In addition, the box-type substation size of said structure is very big, and manufacturing cost is higher, and it is bigger to take up space.

Summary of the invention

The utility model technical problem to be solved is: it is neat, convenient to provide a kind of circuit to connect, and manufacturing cost is lower, less miniature box-type substation takes up space.

The technical scheme that the utility model is taked is: a kind of miniature box-type substation; Comprise casing; First dividing plate that casing laterally is arranged in order, second partition, the 3rd dividing plate and the 4th dividing plate are divided into hyperbaric chamber, transformer room and low-pressure chamber from left to right with casing; In the described hyperbaric chamber primary cut-out is set; Be provided with low-voltage circuit breaker in the low-pressure chamber, be provided with transformer in the transformer room, primary cut-out and transformer are separately fixed at also to be provided with on both sides and the second partition of second partition is convenient to the wall bushing that primary cut-out and transformer lead pass.

The beneficial effect of the utility model is: the both sides that primary cut-out in the miniature box-type substation of the utility model and transformer are separately fixed at second partition; And transformer second partition, the 3rd dividing plate direction are not arranged fin (fin is arranged into other both directions); Equal a tank wall of transformer is used as second partition; And, removed original operation with high pressure corridor just with its mounting panel of being used as primary cut-out; The another one tank wall of transformer is used as the 3rd dividing plate, and just it is used as the mounting panel of low-voltage circuit breaker.Guarantee safe distance the whole lateral dimension of transformer station that dwindles greatly on the basis.In addition, second partition is provided with is convenient to the wall bushing that primary cut-out and transformer stube cable pass, and so, the stube cable between primary cut-out and the transformer directly passes from wall bushing, installs easy to connectly, and cable is neat and orderly.

Description of drawings

Fig. 1 is the utility model front view.

Among the figure, 1, first dividing plate, 2, second partition, the 3, the 3rd dividing plate, the 4, the 4th dividing plate, 5, primary cut-out, 6, low-voltage circuit breaker, 7, transformer.

Embodiment

Below be the utility model preferred embodiment, but therefore do not limit the protection range of the utility model.

With reference to shown in Figure 1; A kind of miniature box-type substation of the utility model; Comprise casing; First dividing plate 1, second partition 2, the 3rd dividing plate 3 and the 4th dividing plate 4 that casing laterally is arranged in order are hyperbaric chamber, transformer room and low-pressure chamber with a casing left side to parting on the right side, and primary cut-out 5 is set in the described hyperbaric chamber, are provided with low-voltage circuit breaker 6 in the low-pressure chamber; Be provided with transformer 7 in the transformer room, primary cut-out 5 and transformer 7 are separately fixed at also to be provided with on both sides and the second partition 2 of second partition 2 is convenient to the wall bushing that primary cut-out 5 and transformer 7 stube cables pass.

Primary cut-out 5 and transformer 7 are separately fixed at the both sides of second partition 2, have dwindled the whole lateral dimension of transformer station to a certain extent.In addition, second partition is provided with is convenient to the wall bushing that primary cut-out 5 and transformer 7 stube cables pass, and so, the stube cable between primary cut-out 5 and the transformer 7 directly passes from wall bushing, installs easy to connectly, and cable is arranged orderly.

Claims

1. miniature box-type substation; Comprise casing; First dividing plate (1) that casing laterally is arranged in order, second partition (2), the 3rd dividing plate (3) and the 4th dividing plate (4) are hyperbaric chamber, transformer room and low-pressure chamber with casing from a left side from parting on the right side; Primary cut-out (5) is set in the described hyperbaric chamber; Be provided with low-voltage circuit breaker (6) in the low-pressure chamber, be provided with transformer (7) in the transformer room, it is characterized in that: primary cut-out (5) and transformer (6) are separately fixed at also to be provided with on both sides and the second partition (2) of second partition (2) is convenient to the wall bushing that primary cut-out (5) and transformer (7) stube cable pass.
