Abstract

The utility model provides a pre-fabricated substation with a good ventilation structure, which comprises a box body, a top cover and a base, wherein the top cover is mounted at the top part of the box body which is mounted on the base, three compartments are arranged inside the box body, namely a high voltage chamber, a transformer chamber and a low voltage chamber in which high voltage switch cabinets, transformers and low voltage switch cabinets are respectively installed; for the box bottom of the transformer chamber, a ventilation hole is formed at the lower part of a mounting rail of the transformer, a box-body louver is arranged at the upper part of the transformer chamber door frame of the transformer chamber, four air exhausters are mounted at the four corners at the top part of the transformer chamber, top cover louvers are arranged on the periphery of the top cover, and one or two base louvers are respectively arranged on the base at both sides of the position corresponding to the transformer chamber. The substation can ensure the radiators at the bottom part and the periphery of the transformer to be fully cooled, the allowable use capacity of the transformer is enhanced, and the service life of the transformer is prolonged.

Description

A kind of preassembled transformer station

Technical field

The utility model relates to a kind of distribution substation of urban distribution network, is specifically related to the prepackage type box-type substation.

Background technology

The preassembled transformer station of extensive use at present, owing to standard GB/T17467 proposes to explicitly call for to the ventilation of transformer room, so its ventilating system is all perfect inadequately.The employing natural draft is arranged, the fin that adopts cooling blower to blow transformer is also arranged, perhaps pull out wind on top, transformer room, the heat that transformer is sent distributes effectively, thereby capacity is used in the permission that has reduced transformer.

Summary of the invention

The purpose of this utility model is to provide a kind of preassembled transformer station with good ventilation structure at the above-mentioned defective of existing preassembled transformer station existence.

The technical solution of the utility model is: a kind of preassembled transformer station, comprise casing, top cover and basis, described top cover is installed in the top of casing, casing is installed on the basis, be divided into three compartments in the casing, be the hyperbaric chamber, transformer room and low-pressure chamber are equipped with high-tension switch cabinet, transformer and low-tension switch cabinet respectively in it; At the bottom of the case of described transformer room, be positioned at the transformer mounting rail below be provided with ventilation hole, the transformer doorframe top of described transformer room has the casing blind window, four air exhausters are equipped with at four angles, top, transformer room, have the top cover blind window around the described top cover, ground around the ratio of basis is raised 50 to 100 centimetres, and respectively drive one or two basic blind window, with convenient air intake in the both sides, position corresponding, basis with the transformer room.

All be equipped with on all ventilation holes and the blind window in the utility model and prevent that toy from entering the steel wire in the casing.

The beneficial effects of the utility model are: the utility model can make the radiator around transformer bottom and the transformer fully be cooled off, and improves transformer and allows the use capacity, increases transformer useful life.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments:

To shown in Figure 5, top cover 1 of the present utility model is contained in the top of casing 3 as accompanying drawing 1, and casing 3 is installed on the preassembled transformer station basis 4, and blind window 6 is higher than terrace 5, and apparatus arrangement is the order font in the casing, is followed successively by hyperbaric chamber 10, transformer room 11 and low-pressure chamber 12.Cold wind sucks from the basic blind window 6 on the preassembled transformer station basis 4, and the ventilation hole 8 below the transformer mounting rail is to transformer bottom and the cooling of radiator all around thereof; Absorbed the hot-air of transformer heat, risen to casing top, one tunnel casing blind window 2 through transformer doorframe top is dissipated to outside the casing, and another road is drawn to the case top through air exhauster 7, is dissipated to outside the casing by the top cover blind window 9 around the top cover 1.
