Box-type transformer substation

Abstract

The invention discloses a box-type transformer substation, comprising a high-pressure chamber, a low-pressure chamber and a transformer chamber. The box-type transformer substation is characterized inthat the high-pressure chamber, the low-pressure chamber and the transformer chamber are arranged in a tripod shape in the box-type transformer substation, the high-pressure chamber and the low-pressure chamber are enclosed structure, the transformer chamber is half-enclosed corridor-type structure, and the side faces of the high-pressure chamber and the low-pressure chamber are provided with ventilation and heat dispersion holes. In the box-type transformer substation with the structure, a transformer is placed in the half-enclosed transformer chamber and exposed in air under the condition of ensuring damp-proof, rustproof, dustproof, rat proof, fireproof and heat insulation, which is favorable for better heat dispersion of the transformer and steady operation of the transformer and high-and-low voltage devices; simultaneously, the shell separation of the transformer and the high-and-low voltage devices is convenient for maintenance, examination and repair, ensures the separation ofthe transformer and high voltage components and can avoid pollution in the oil box of the transformer. The heat dispersion holes arranged on the side faces of the high-pressure chamber and the low-pressure chamber are favorable for ventilation and internal temperature reduction.

Description

technical field [0001] The invention relates to a power transformation device, in particular to a box-type transformer substation. Background technique [0002] In the power system, box-type substations are widely used. Box-type substations are a kind of factory prefabricated indoor / outdoor compact power distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage power distribution devices according to a certain wiring scheme. Realize functions such as high-voltage power receiving, transformer step-down, and low-voltage power distribution. The box-type substation is set in a steel structure box, with mechatronics and fully enclosed operation. It is especially suitable for urban network construction and transformation. It is a brand-new substation that has emerged after the civil substation. [0003] The existing box-type substations are divided into two categories: European-style box-type substations and American-style box-type ...

AI Technical Summary

Problems solved by technology

[0004] At present, most box-type substations are fully enclosed. For example, the patent ZL01239772, while ensuring moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, and heat insulation, also has the following disadvantages: transformers and substations. The heat generated by the components cannot be dissipated in a timely manner, causing the temperature in the inner space of the box-type substation to be too high, and in serious cases, the components will fail; at the same time, it is inconvenient to maintain the transformer if the transformer is arranged in a small space. overhaul
