Problems solved by technology
In the transformation project of substation automation, the original equipment does not have PT cabinets, but only one reserved manhole, but at this time the user needs to install PT cabinets and reserve the manhole. The difficulty of construction increases, and a perfect solution has not yet been developed

The invention relates to a transformer substation occupying a small area, which comprises a transformer, a cement housing, a switch cabinet PT interval, a switch cabinet outgoing wire interval and a manhole. The cement housing at the upper part of the manhole is provided with a support consisting of a horizontal plate and supporting legs. Between two supporting legs at the left side and in communication with the switch cabinet outgoing wire interval, a cable channel is formed. The upper part of the horizontal plate is provided with a suspension empty type PT cabinet; and the horizontal plate is provided with a wire penetration hole in communication with the suspension type PT cabinet. Between the lower bottom of the horizontal plate and the cement housing, a manhole interval is arranged. The transformer substation of the invention is cleverly designed. With simple modifications, the transformer substation occupies a small area. Through the proper planning for the internal space of a current transformer substation and under the condition that the current foundation is not changed, a PT cabinet is introduced and the manhole is kept. This design meets the client's requirement, saves the construction cost, reduces the construction difficulty and increases the construction speed.
Description
technical field [0001] The invention relates to the technical field of power equipment, in particular to a substation with a small footprint. Background technique [0002] Ordinary substations include transformers, switchgear PT intervals, switchgear outlet intervals, and manholes, which are combined and installed in a cement shell to become a substation. The main busbar of the PT cabinet and the main busbar of the switch outlet interval are connected to each other to make it work. In the transformation project of substation automation, the original equipment does not have PT cabinets, but only one reserved manhole, but at this time the user needs to install PT cabinets and reserve the manhole. Construction increases the difficulty, and a perfect solution has not been researched yet. Contents of the invention [0003] The purpose of the present invention is to make up for the deficiencies of the prior art, and to provide a substation with a small floor space that can mee...
