Description

Technical Field

[0001] The utility model relates to a box-type transformer substation. Background Art

[0002] The box-type substation is a compact complete set of power distribution equipment that integrates high-voltage switchgear, low-voltage switchgear, distribution transformer, electric energy metering equipment and reactive power compensation equipment. The roof of the box-type substation is an important part of its external structure. In order to ensure its waterproofness and prevent animal entry, the existing box-type substation roof is often stamped in one piece. The roof cover is often fixed to the roof side plate and the roof front plate by direct welding or bolt connection. However, due to the harsh outdoor environment and some force majeure factors, the roof cover is very easy to be damaged. It needs to be completely dismantled for maintenance, which is time-consuming, labor-intensive and costly. Therefore, it is necessary to improve and optimize it without affecting the protection.
