Abstract

The invention discloses an extra-high voltage transformer maintenance operation device and a maintenance method, and belongs to the technical field of transformer maintenance, the extra-high voltage transformer maintenance operation device comprises a safety belt suspension mechanism fixed on a bolt at the top of a transformer, and a maintenance operation platform arranged on a panel of a low-voltage bushing ascending flanged base of the transformer; the safety belt hanging mechanism comprises a safety belt, a connecting piece arranged at the upper end of the safety belt and a mounting assembly used for mounting the connecting piece to a bolt at the top of a transformer. The maintenance operation platform comprises a supporting plate, ladders and mounting bases, the ladders are arranged onthe two sides of the supporting plate respectively, the mounting bases are arranged on the lower portions of the two ladders respectively, and the two mounting bases are connected with two transformer low-voltage bushing ascending flanged base panels through bolts respectively. The device conforms to safety operation specifications, personal safety of maintainers is guaranteed, and the device ishigh in use convenience.

Description

technical field [0001] The invention relates to the technical field of transformer maintenance, in particular to an ultra-high voltage transformer maintenance operation device and maintenance method. Background technique [0002] State Grid Henan Maintenance Company is responsible for routine maintenance of B / C type UHV equipment in Henan main power grid. The structure of UHV transformer is different from conventional EHV transformer. 3 meters and above the ground. For routine maintenance and high-voltage testing of UHV transformers, it is necessary to remove the lead wires connected to the medium and low voltage bushings and install test lines. belt way. However, it is difficult to set the suspension points on the transformer body and there is no special place to hang the safety belt. It is usually tied to the oil pipeline, fire pipeline, and bushing, and there are safety belt violations such as low hanging and high hanging and loose hanging. , There is a potential safet...
