A power supply company can install an electric energy meter on each 10kV line for charging, the electric energy meter is positioned at an upper port of a transformer and is metered by adopting a mode of accessing through a combined transformer, and each electric energy meter is provided with a special transformer acquisition terminal for acquiring information such as electric quantity, demand, voltage, current and the like and transmitting the information to the power supply company in a remote communication mode. The transformer in the power distribution room and the like are user assets, users can independently switch equipment according to needs without informing a power supply company, in actual use, in order to save electricity charges (the transformer is lost when no load, and an electricity meter can perform metering), the users can stop a certain path of power supply, or users with a certain path of power supply failure cannot timely process the power supply, so that the line metering and collecting equipment loses working power supply, and the user fails in power utilization information collection.
At present, after the acquisition of the special transformer fails, a power supply company firstly utilizes a system to perform troubleshooting, and if the system fails to troubleshoot the problem, the power supply company arranges the on-site troubleshooting. Normally, such problems as blackouts can only be detected by on-site troubleshooting, but cannot be handled even if the trouble is detected (because the power supply company has no disposal right for the user's assets). At the moment, the problems can be remarked, and then special investigation is carried out at intervals in the follow-up process so as to master the field situation. Sometimes, a user already operates the transformer, but the fault of the metering and collecting equipment is mistaken as the power failure of the transformer, so that the power utilization information of the user is not collected for a long time. The existing operation and maintenance mode consumes a great deal of working energy but has low efficiency and quality.
