Buried-in non crystal alloy pre-installed transformer sub-station

Abstract

The invention discloses an embedded amorphous alloy prefabricated substation, which comprises a first box composed of a box wall and a cover plate made of waterproof building materials embedded in a ground pit with a high-voltage cabinet and a low-voltage cabinet inside , the pit also includes a second box body composed of a box wall and a box cover, the second box body is made of water seepage building materials, the transformer is arranged in the second box body, and the second box body The box cover of the body is provided with an air inlet and an air outlet, and an air inlet pipe connected to the waistline of the transformer is arranged at the air inlet, and a cable inlet and outlet hole is arranged on the wall of the second box body. The technical scheme of the invention realizes the underground installation of the power distribution equipment, ensuring that there is no power distribution facility on the ground. It is more convenient and flexible to put the transformer box and the high and low voltage distribution box in their respective pits, and the maintenance is also very convenient in the future. drainage system.

Description

technical field [0001] The invention relates to a substation, in particular to an embedded amorphous alloy pre-assembled substation. Background technique [0002] At present, most of the substations are set up on the ground. With the increase of the capacity of the substation, the volume of the substation is getting bigger and bigger. Although the appearance of these substations has been designed very beautifully, in today's society where land resources are decreasing, the substation The occupied land area cannot be ignored, so an underground substation that does not occupy land came into being, especially in some places that have strict requirements on the ground landscape, such as large stadiums, etc., it is a necessary basic requirement for the substation to be buried underground. However, existing underground substations (see figure 1 ) The medium and high voltage cabinet 1, the low voltage cabinet and the transformer 3 are all in a waterproof concrete prefabricated box...

Problems solved by technology

[0002] At present, most of the substations are set up on the ground. With the increase of the capacity of the substation, the volume of the substation is getting bigger and bigger. Although the appearance of these substations has been designed very beautifully, in today's society where land resources are decreasing, the substation The occupied land area cannot be ignored, so an underground substation that does not occupy land came into being, especially in some places that have strict requirements on the ground landscape, such as large stadiums, etc., it is a necessary basic requirement for the substation to be buried underground. However, existing underground substations (see figure 1 ) The medium and high voltage cabinet 1, the low voltage cabinet and the transformer 3 are all in a waterproof concrete prefabricated box 5, the two sides of the box 5 are in the shape of a ladder with a large top and a small bottom, and the box 5 is buried in the pit 4 Closed by the pit cover 6, the middle of the box 5 is separated by a partition 7 with a door and a ventilation gap 72 at the bottom to separate the high and low voltage cabinets 1 and 2 from the transformer 3 into a high and low voltage power distribution room 51 and the transformer room 52, on the pit cover plate 6 where the high and low voltage power distribution room 51 is located, there is an inlet and outlet 60 for the maintenance personnel to enter, and its air inlet and outlet 61, 62 are respectively located on the outside of the high and low voltage power distribution room 51 and On the pit cover plate 6 of the protruding part of the outside of the transformer 52 and on the lower box wall and seal with an iron fence, if it rains, the rainwater can flow into the pit along the iron grating of the protruding part and pass through the supporting When the drainage system is not perfect, a large amount of accumulated water will enter the pit 4 and if it cannot be discharged smoothly, it will eventually enter the high and low voltage power distribution room 51, resulting in serious accidents such as short circuit
