State Grid Tianjin Power Company overhaul Sun Weibai innovative studio
Achievements:
In the operation and maintenance of a large number of three-column / two-column horizontal rotary disconnectors on the power grid, in order to eliminate the safety problems caused by using traditional insulation ladders, scaffolding and bucket-arm vehicles in the traditional maintenance mode, assembly Slow down by substation terrain constraints and other unfavorable factors to shorten the equipment blackout maintenance time and improve the reliability of power supply, combined with the structural characteristics of isolating switch, comply with the State Grid Corporation of power safety regulations and live working with the basic requirements of the insulation hard ladder general technical requirements , Developed a fast-mounted high voltage isolation switch insulation repair platform.
The platform is designed to be mounted and disassembled quickly. The connections of the structural components are all in the form of plugging and buckling. The connection is convenient and reliable, and the single or multiple shelves can be used at the same time, greatly improving work efficiency. In addition, the platform can be firmly fixed in the channel base of the disconnector, the staff can stand on a dedicated operating pedal to carry out the work, the solid structure and comprehensive safety measures so that staff at work is always in the maintenance platform maintenance , And solve the problem of hanging the seat belt without the type of high-altitude operation, eliminating the habit of illegal (climbing porcelain, etc.), greatly improving the level of safe operation at the maintenance site.
At present, the platform has been popularized and applied within the scope of the State Grid Tianjin Power Company. Compared with the traditional maintenance methods, this platform is used for overhauling the isolating switch of this type. Each group can save power outage over 3.5 hours on average. The annual output is expected to achieve a total profit of over 670,000 yuan. The results in February 2012 won the national utility model patents.
