Problems solved by technology
[0002] Relevant statistics show that 30% of distribution network maintenance costs are spent on distribution cabinets, and 20% of them are used for minor repairs and routine maintenance of distribution cabinets; in addition, according to statistics, 15% of distribution cabinet failures are Due to incorrect maintenance, the overhaul of the distribution cabinet is completely disassembled, which is time-consuming and expensive, up to 40% of the entire distribution cabinet, and the disassembly and reassembly will cause many defects. The resulting accident examples There are too many to enumerate. It is still a controversial issue for which parts (or important components) of the power distribution cabinet and how long they need to be replaced. In fact, in the current relatively conservative planned maintenance, it often happens that many parts run a lot The performance is still good when it is updated after a year, but due to failure to find out in time, a defect in a certain component will cause a power grid accident from time to time
