Problems solved by technology

[0004] At present, most box-type substations are fully enclosed. In the case of moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, and heat insulation, there are also the following disadvantages: the heat generated by the transformer and the components inside the substation Failure to disperse in a timely manner causes the temperature in the inner space of the box-type substation to be too high, and in severe cases, component failures are caused; at the same time, it is inconvenient to maintain and overhaul the transformer if the transformer is arranged in a small space

Abstract

The invention relates to a box-type transformer substation which comprises a house-shaped housing, wherein the inside of the house-shaped housing is divided into three units which are respectively a transformer unit, a high voltage unit and a low voltage unit, the transformer unit is arranged between the high voltage unit and the low voltage unit, the low voltage unit comprises two separated low voltage cabinet sets which are mutually connected through a bus bridge, and an operating corridor is arranged between the two separated low voltage cabinets. The box-type transformer substation is reasonable in distribution of the inside space, and is convenient for maintenance.

Description

technical field [0001] The invention relates to a substation, in particular to a regional substation. Background technique [0002] In the power system, substations are widely used. Substations are prefabricated indoor / outdoor compact power distribution equipment that integrate distribution transformers and high-voltage and low-voltage power distribution devices according to a certain wiring scheme to realize high-voltage power receiving and transformer step-down. High voltage, low voltage power distribution and other functions. The 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 new type of substation that has emerged after the civil substation. [0003] The existing substations are divided into two categories: European box-type substations and American-style box-type substations according to different product structures and components. These two...
