Hai Lunzhe insulated arm aerial vehicle power high altitude non blackout working
In July 27th, Hai Lunzhe XHZ5131JGKA insulated aerial vehicle arm to help the State Grid Tibet Electric Power Co. Ltd. Lhasa power supply company in Tibet, Lhasa is about 4000 meters above the plateau, the successful implementation of the high altitude 10 thousand volt electric operation, fill the blank of live overhaul at high altitudes in Tibet.
State Grid Tibet electric power company Lhasa power supply company to seriously implement the "national Power Grid Corp of Ministry of transport inspection in high altitude area power operation" and "national network of Tibet Electric Power Company Limited blackout job requirements, the distribution of live working in high altitude region of Tibet as a key work. The successful completion of the live operation makes the rapid processing fault and defect time of the distribution network of the plateau greatly reduced, and improves the reliability of the power supply in the distribution network.
It is understood that in the three or four kilometer high altitude area, there is a higher demand for professionalism and safety in non power outage operation. We should grasp the altitude correction method and the insulation coordination method of live working gaps in live line operation at high altitude area. In order to ensure the smooth operation of the charged, correction of Lhasa Hai Lunzhe has used the vehicle related index according to the elevation of 4500m, the correction coefficient of up to 1.54, power frequency withstand voltage and leakage current are in line with the high altitude charged operation requirements; the effective insulation length of the car changed from 1m to 1.2m. The premise of 10kV charged operation without arms, the owner of the insulation pre stretch segment has more than 1.2m, the maximum guarantee operation safety. In addition, Hai Lunzhe related technical service personnel to Lhasa several times and the first live working team for practical communication, on-site security of operating vehicles. The final operator overcame the impact of the special geographic climate on the electrified operation of the distribution network, and successfully completed all the operations.
With the gradual advancement of the construction of the "large maintenance" system of the national Power Grid Corp, it is inevitable to carry out the professional distribution network without power stop operation. It is of great significance to promote the implementation of electrified operation in the high elevation area power grid to improve the overall reliability of the national grid operation and reduce the loss of the power grid load. Hailunzhe study will also further strengthen the plateau area of non blackout work, live working comprehensive service scheme provided by the insulating arm aerial vehicles, power repair vehicles, cars and other products which bypass work for customers, continuously improve the reliability of power supply in high altitude area.
