Entering May，The Mechanical and Electrical Materials Management Center of Hanjiawan Coal Company insists on prevention first、Work ideas for advance deployment，Be prepared for safe power supply in mines under extremely severe weather。
The Mechanical and Electrical Materials Management Center focuses on eliminating power supply shortages m88 reviewin spring，Overall arrangements、Plan ahead，Find weak points in the power supply system，Eliminate 35KV power supply overhead lines in mines、The tower base is defective，Ensure early detection of hidden problems in the power supply system、Early processing，Achieve safe operation of power supply system。
Hanjiawan Coal Company 35KV line、The tower is in a lightning-prone area all year round，In summarizing the unsafe factors that occurred in the power supply system during the extreme weather we dealt with in previous years，The Mechanical and Electrical Materials Management Center carefully organizes professional power supply maintenance test personnel，It took 4 days to measure 6 of the mine’s 35KV overhead lines in South Korea.53KM，Shihan overhead line plan 5.90KM dual power supply line inspection tower by tower and basis，Tighten the connection of the galvanized flat iron of the lightning inducing device，Conduct a full coverage inspection of the 47 towers and foundations supporting overhead lines along the line，Retest all grounding resistances m88 casinoof 47 tower grounding devices，Understand the actual situation around the line tower base and carry out prevention and key management and control。
Hanjiawan Coal Company 35KV power supply overhead line、Tower base，Being in the wilderness for a long time、Running around mountain areas，Withstand wind all year round、Rain、Ice and other natural weather baptism，In case of extremely bad weather，The line tower base is particularly susceptible to external disasters。Strengthening self-maintenance and inspection，Taking power supply shortage in spring as the starting point，While doing inspections and inspections，When the grounding system with lightning inducing device is larger than the standard value，Develop measures for on-site organization and processing，Eliminate defects，Ensure safe operation of facilities。（Wang Yongliang）
