Embodiment Construction

[0011] Referring to Fig. 1 to Fig. 3, a basic structure for installing an oil-immersed transformer of the present invention is arranged in a transformer room 1, and the size of the transformer room is determined according to the weight and shape of the transformer.

[0012] The transformer room 1 has an integral box-shaped foundation 2 for installing an oil-immersed transformer. An oil collecting tank 3 is provided around the box-shaped foundation 2, and the oil collecting tank 3 can discharge transformer accident oil and store it. An oil sump 4 is arranged at the end of the oil sump 3, and the oil sump 4 communicates with the oil sump 3, so that it is convenient to extract and clean up the discharged oil. The periphery of the box foundation 2 is a cement floor 5. Several flat steels 6 are pre-embedded in the middle of the box-shaped foundation 2, and these flat steels 6 are fixed by reinforcing cables 7, which is beneficial to bearing and fixing the weight of the transformer ...

Abstract

The invention relates to a base structure used for installing an oil immersed transformer. The invention is arranged in a transformer room where a box-shaped base is arranged. An oil collecting groove is arranged around the internal part of the box-shaped base. The oil collecting groove is communicated with an oil collecting pit positioned at an end of the oil collecting groove. A cement level-ground is arranged on the outer edge of the box-shaped base. A plurality of flat bars are pre-embedded in the middle of the box-shaped base and are fixed by reinforced cables. And a plurality of flat bars are pre-embedded in a wall of the transformer room and a steel hook is also pre-embedded on the wall so as to pull the transformer. By adopting the structure of the transformer box-shaped base of the invention, the structure can be free from a building frame base and the weight of the transformer is born by the box-shaped base. Then, although the box-shaped base causes slight settlement to the ground, the adopted flexible connection of cables can not be affected. The transformer base of the invention needs no piling so as to save an investment cost. The arrangement of the oil collecting grooves around the internal part of the box-shaped base can drain the oil for storage so as to meet fire control requirement.

Description

technical field [0001] The invention relates to the installation of oil-immersed transformers, in particular to a basic structure for installing oil-immersed transformers. Background technique [0002] The installation and layout design of the existing oil-immersed transformer room is mainly based on the standard 03D201-4 formulated by the China Building Standard Design and Research Institute, which is named "10 / 0.4kV Transformer Room Layout and Installation of Commonly Used Equipment and Components in Power Transformation and Distribution Stations". The fields and contents involved in this standard are relatively comprehensive, but the technical requirements are too complicated. Its structure mainly adopts the beam-type transformer foundation, and the weight of the transformer is usually pressed on the beam-type structure. In addition, transformer accident oil is directly discharged into the ground or a deep underground oil pit is dug for storage. This has the problem of t...
