Problems solved by technology

[0008] 2. Take up a lot of space
In addition, it is not convenient for the operation and maintenance of the high-pressure room and the low-pressure room, because the doors of the high-pressure room and the low-pressure room may be blocked by the ground
Furthermore, it is difficult to dissipate heat in the transformer room with a large amount of heat, and it is impossible to achieve ventilation around it.
[0009] 3. If the substation is completely buried underground, the construction cost of the basement will be high, and it is necessary to provide artificial cooling and ventilation for the basement

Embodiment Construction

[0024] The specific embodiments of the prefabricated substation of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] Such as Figure 4 , 5 As shown in , the prefabricated substation of the present invention includes a high-voltage room 1, a low-voltage room 2, a transformer room 3, a ventilation window 4, and a cable inlet and outlet 5. The high pressure chamber 1 and the low pressure chamber 2 are provided with a door 9 .

[0026] A heat-insulating and fire-proof layer 6 is provided between the high-voltage chamber 1 and the low-voltage chamber 2 and the transformer chamber 3 to prevent the heat emitted by the transformer 14 in the transformer chamber 3 from being uploaded to the high-voltage chamber 1 and the low-voltage chamber 2, thereby affecting the Appliance control. The whole station body is an integral frame structure, including frame 11, high-voltage chamber 1, low-voltage chamber 2, side panels 10 of tra...

Abstract

The pre-assembled converting station includes high-voltage chamber, low-voltage chamber and transformer chamber, the described high-voltage chamber and low-voltage chamber are placed over the transformer chamber, the upper portion of said transformker chamber is equipped with a ventilating radiation window exposed to the weather, and when it is used, the half of the transformer chamber is embedded under the ground, the ventilating radiation window is positioned on the ground surface so as to implement natural ventilation and radiation of transformer.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a prefabricated substation comprising a high-voltage room, a low-voltage room and a transformer room. Background technique [0002] In power transmission and application, in order to convert high-voltage (1-52kV) electric energy in the grid into low-voltage (0.4kV) electric energy, prefabricated substations are widely used. Prefabricated substation is the term of the current national standards and IEC standards. Previously, prefabricated substations were also called box-type substations, combined substations, complete substations, compact substations or European box-type substations. [0003] In GB / T17467-1998 "High Voltage / Low Voltage Prefabricated Substations" national standard and IEC1330: 1995 "High-voltage / low-voltage prefabricated substations" International Electrotechnical Commission standard, the main components of prefabricated substations are transformers, high volt...
