Sand-proof transformer substation applied to cold zone

Abstract

The invention discloses a sand-proof transformer substation applied to a cold zone. The sand-proof transformer comprises a shell (1), wherein the inside of the shell is divided into a high-pressure chamber (2), a low-pressure chamber (3) and a transformer chamber (4) by partitions (14); the transformer chamber (4) is formed between the high-pressure chamber (2) and the low-pressure chamber (3); a metering chamber (5) is formed in each of the high-pressure chamber (2) and the low-pressure chamber (3); a controllable heating strip (6) is arranged on the inner surface of the shell (1); and the shell (1) is also provided with a sand-proof ventilating system (8). The sand-proof transformer substation has the advantages that because the controllable heating strip is additionally arranged on the inner side of the shell, the problem that a transformer door is opened difficultly due to freezing in frigid weather is effectively solved; a ventilating hole is designed, so that a ventilating effect is high, foreign matters such as sand grains can be prevented from entering the shell, and components in the shell are protected.

Description

technical field [0001] The invention relates to a substation, in particular to a sand-proof substation applied in cold areas. Background technique [0002] In order to transmit the electric energy from the power plant to a distant place, the voltage must be raised to become high-voltage electricity, and then the voltage is lowered as needed near the user. This work of raising and lowering the voltage is done by the substation. The main equipment of substations are switches and transformers. Existing substations are more and more widely used, but when they are used in cold areas, the casing will freeze, which often leads to the inability to open the box door and inconvenient maintenance; and when it is used in areas with excessive wind and sand, sand often passes through The ventilation hole enters the housing, causing power failure and leakage. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the current technolog...
