Fully insulated buried substation

Abstract

A fully insulated buried substation comprises a frame and a high-voltage unit, a transformer unit and a low-voltage unit which are arranged in the frame, wherein a transformer is arranged in a transformer protection box; the lower half frame, the transformer protection box and the transformer are arranged underground; the high/low-voltage units are positioned on the transformer unit and are arranged above the ground; a plurality of heat pipes are vertically arranged in transformer oil grooves; the upper parts of the heat pipes are respectively positioned at one side of the high-voltage unit and one side of the low-voltage unit; the moving contact of a high-voltage solid insulated switch is connected with an operating mechanism; and secondary-side connection terminals of the transformer are connected with the upper ends of low-voltage switches by penetrating through low-voltage sleeves via the cables. The substation adopts the modular integrated combination structure and the components can be replaced separately. The substation is scientific, reasonable and creative in design, small in volume and convenient to maintain and operate since the monitor display devices are arranged at one side, reduces energy consumption, is easy to install, strong in economical applicability and stable and reliable, and has good development prospect. The substation is suitable for power supply departments.

Description

technical field [0001] The invention relates to a substation, specifically a fully insulated buried substation using a solid insulated switch integrating a load switch, a fuse, an isolation fracture and a grounding function, a low-loss oil-immersed transformer, and a low-voltage feed-out modular integrated combination structure. substation. Background technique [0002] The substation is an indispensable and important part of the power system. It mainly plays the role of distributing electric energy, regulating voltage, protecting the safety of the power grid, and improving the power supply quality of the power grid. It is also one of the equipment that consumes energy in the power grid. The key role of the substation determines that its reliability cannot be ignored. At the same time, the energy consumption problem is the most important problem that the power supply system needs to solve urgently. [0003] At present, general-purpose substations are set up in isolated area...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a fully insulated buried substation with a modular structure that is easy to install, less energy consumption, and safe and reliable in view of the current substations that occupy a large area, high operating costs, and potential safety hazards.
