Transformer device with oil pool

Abstract

The invention aims to disclose a transformer device with an oil pool. The transformer device comprises a low-voltage cabinet, a high-voltage cabinet, a transformer and an accident oil storage pool, and is characterized in that the low-voltage cabinet and the high-voltage cabinet are respectively arranged at two sides of the transformer and are mutually connected with the transformer; and the accident oil storage pool is arranged at the bottoms of the transformer and the high-voltage cabinet and is communicated with the transformer and the high-voltage cabinet, and the outer side of the transformer is respectively provided with an accident oil drainage (sampling) valve. Compared with the prior art, an integration concept is adopted, the transformer and the accident oil storage pool are integrated, welding of installation equipment is completed in a equipment plant, the influence of winter construction can be conveniently reduced, project site civil engineering work is reduced, the number of constructors is reduced, the project construction period is shortened, the site construction quality is improved, and the purposes of the invention are achieved.

Description

technical field [0001] The invention relates to a transformer device, in particular to a transformer device with its own oil pool. Background technique [0002] According to the requirements of the national standard GB50060 "Code for Design of 3-110kV High Voltage Power Distribution Equipment", when the oil volume of a single electrical equipment outside the house is more than 1000kg, oil storage or oil retaining facilities should be installed. When oil storage or oil retaining facilities containing 20% ​​of the oil volume are provided, facilities are to be provided to discharge the oil to a safe place without causing a pollution hazard. When the above requirements cannot be met, oil storage or oil retaining facilities capable of holding 100% of the oil volume shall be provided. [0003] Sub-array step-up transformers basically need to be equipped with emergency oil pools to meet the requirements of design specifications. [0004] In the current photovoltaic power station ...

AI Technical Summary

Problems solved by technology

[0004] In the current photovoltaic power station design scheme, most of the sub-array step-up transformers are brick-concrete structures with emergency oil storage pools. Due to the short construction period of photovoltaic power stations, urgent tasks, and many applications of new technologies and new equipment, a large number of civil works and equipment installations are required. The work needs to be completed quickly in a large construction area, which puts huge pressure on the design, construction, management, and quality supervision of the power station

At the same time, due to policy reasons, photovoltaic power plants involve construction in winter, and the temperature in winter drops. Pond concrete strength has a great influence
