Introduction to the maintenance method of multi-user energy meters

When checking the capacitors contained in the power supply for a multi-user energy meter , it is necessary to make a preparation in advance, short the capacitors first. This process cannot be arbitrarily operated and must be completed in a specific way, otherwise it is easy to burn the core. Therefore, when operating, you can use a lead wire to connect the small light bulb at both ends until the light operation can be stopped.
       The meter with normal power consumption accounts for 77.03%. The abnormal cause requires long-term monitoring of battery power consumption and anatomical analysis. After research, the battery undervoltage problem at the customer detection end is mainly manifested as large power consumption, which is a process problem, and the battery undervoltage that occurs after being connected to the network is mainly "incoming" or "environment" problems, such as "salt fog" , High temperature and humidity.
       This kind of inspection sometimes needs to be performed in a special environment. If it is encountered in a humid environment, it is very important and necessary to check whether the points are smooth. It is mainly because problems are easy to occur in such an environment. It is the corrosion of the constituent materials.
       The internal maintenance of multi-user energy meters must also be completed. During the inspection, it is also necessary to pay attention: if there is insulating material on the nodes and it is necessary to complete the inspection, use ordinary welding methods, so that it will not take much time. It can also prevent the surface paint layer from falling off completely.

       The multi-user energy meter has the measuring function of the ordinary energy meter. In particular, the user first purchases electricity, and can use electricity only after the electricity is purchased.
