Double-level pressure compensation type underwater transformer

Abstract

The invention relates to a transformer applied to the deep sea environment and particularly relates to a double-level pressure compensation type underwater transformer having properties of light weight and high reliability. The transformer includes an outer casing, an inner casing, a pressure compensator, a transformer, a cable, an oil tank and a cable sealing cabin. The transformer is characterized in that the inner casing is mounted in the outer casing, the transformer is mounted in the inner casing, the oil tank is fixed on an upper cover of the inner casing, the cable sealing cabin is fixed to an upper cover of the outer casing, the cable penetrates through the upper cover of the outer casing and the upper cover of the inner casing through a watertight joint mounted on an upper cover of the cable sealing cabin and is then connected with the transformer, the upper cover of the outer casing is covered with an oil injection plug, the bottom of a side wall of the outer casing is provided with an oil drain plug and the pressure compensator, and the pressure compensator communicates with an inner chamber of the outer casing to achieve pressure compensation. The transformer is advantaged in that the transformer is compact in structure, is simple to assemble, is convenient to replace and maintain and has strong adaptability, stable operation and strong reliability in the severe environment.

Description

technical field [0001] The invention relates to a transformer used in a deep sea environment, in particular to a light-weight, high-reliability double-layer pressure-compensated underwater transformer. Background technique [0002] In marine engineering, especially in deep-sea underwater operations, the reliable and stable operation of underwater transformers is a necessary condition for energy supply of underwater equipment. In the harsh environment of the deep sea, especially in the case of large depths, higher requirements are put forward for the pressure resistance and reliability of the underwater transformer shell, and for the sealing of the underwater transformer shell. Under the constraints of deep-sea environment space, weight, and underwater equipment requirements, the existing underwater transformers cannot meet the needs. Next, the demand for the complete equipment. It can be seen that in this technical field, especially the underwater transformer used in the d...
