Compared with the traditional wall-mounted electric energy meter, the rail-mounted electric energy meter has the characteristics of small size and easy installation. However, the existing rail-mounted electric energy meter needs to clamp the case on the guide rail when installing, and the second is from the guide rail. When taking off the electric energy meter, it takes a lot of force to remove it from the guide rail. In the process of installation and disassembly, careless force will easily cause damage to the case of the electric energy meter on the rail, making it unable to continue to be fixed on the rail. On the guide rail, not only that, due to the small size of the guide rail electric energy meter, the heat generated by the internal circuit components is easy to accumulate and cannot be dissipated. After long-term operation, the internal ambient temperature of the guide rail electric energy meter gradually rises, which is easy to reduce. The service life of the circuit components in the environment also affects the measurement accuracy of the meter, which in turn reduces the practicability of the rail type electric energy meter.
