Problems solved by technology

[0002] As one of the important equipment in the power system, the isolating switch is mainly used to create an obvious disconnection point during equipment maintenance, so that the equipment to be repaired is isolated from the operating equipment. At present, in the 110KV substation, the isolating switch plays an important role in the operation of the grid. At present, the substation needs to carry out regular routine tests on the isolating switch, including grounding resistance test, switch body, isolating switch and bushing insulation resistance, voltage transformer insulation resistance, isolating switch inspection and maintenance, and For the replacement and installation of the isolating switch, the existing detection method usually requires the staff to climb to the isolating switch 4-6m above the ground, and hang the grounding wire or test line on the grounding knife contact, or hang it through the insulating rod. It is very inconvenient for the staff to operate, and there are potential safety hazards
When replacing or installing the isolation switch, it needs to be installed with the help of a detection platform, but the existing detection platform has few functions, and the isolation switch needs to be manually lifted to the detection platform, and it is very inconvenient to take and place the isolation switch, which may easily cause injuries or fall. risk, or directly hoist the isolating switch to the place where it needs to be installed, and then install it by manual dragging, which is time-consuming and laborious, and has a low safety factor; therefore, it is necessary to provide a maintenance platform for substation routine tests with reasonable structure, high stability, and convenient inspection and installation. is very necessary

Abstract

The invention relates to an overhaul platform for routine tests of a transformer substation. An upper transverse fixing frame and a lower transverse fixing frame are welded to the upper end and the lower end of a vertical fixing frame respectively, a supporting plate and a climbing ladder are arranged on the lower transverse fixing frame, the supporting plate is arranged on the two sides of the climbing ladder, a sliding connecting plate is arranged behind the supporting plate, and a rear supporting block and a front supporting block are arranged on the upper portion of the supporting plate. Asliding connecting block is further arranged behind the sliding connecting plate and arranged on a pull-up belt, one end of the pull-up belt is arranged on a belt wheel of a pull-up motor, the otherend of the pull-up belt is arranged in a rotating box, the pull-up motor is arranged on a fixing plate of a lower transverse fixing frame, and a rear baffle is arranged between the upper transverse fixing frame and the lower transverse fixing frame. A rectangular hole is formed in the rear baffle, a sliding connecting block moving up and down is arranged in the rectangular hole, fixed sliding blocks are arranged on the two sides of the rear portion of the supporting plate, fixed sliding rails are arranged on the two sides of the rear baffle, and the fixed sliding blocks are matched with the fixed sliding rails; and the overhaul platform has the advantages of being reasonable in structure, high in stability and convenient to detect and install.
