Electric energy meter capable of timely controlling temperature and control method

By setting a phase change material layer on the insertion terminal of the power meter, the phase change and melting of the phase change material causes the membrane to swell and sense the pressure change of the pressure sensitive element. The control system turns on the heat dissipation control method, solving the problem of untimely control of the power meter temperature and improving safety.

AI Technical Summary

Technical Problem

The thermosensitive devices of existing power meters are inaccurate in temperature measurement, resulting in untimely control of the power meter temperature, which poses safety hazards.

Method used

A detection device including an insertion terminal of a phase change material layer is designed. The membrane swells by the phase change melting of the phase change material, causing the pressure-sensitive element to feel the pressure change, so that the control system turns on the heat dissipation control method to adjust the temperature of the electric energy meter.

Benefits of technology

Although the specific temperature value cannot be accurately detected, it can control and adjust the temperature in a timely manner when the internal temperature of the electricity meter is high to avoid safety accidents caused by untimely temperature control.
