[0002] The multifunctional power meter is a self-developed multifunctional intelligent meter with programmable measurement, display, digital communication and electric energy pulse transmission output. It can complete electricity measurement, electric energy metering, data display, collection and transmission. The multifunctional power meter is widely used in substation automation, distribution automation, intelligent buildings, and internal enterprise electric energy measurement, management and assessment. Among them, the sensor combination is an indispensable part of the power meter.

[0004] Although the power meter is provided with a panel, a meter body, a protective shell, a cutting structure, a power cord and a smoke sensor, when the meter leaks electricity and catches fire, it will be detected by the smoke sensor.

At the same time, the buzzer sounds an alarm to remind the staff to realize the fire alarm function of the meter. The sensor may be damaged over a long period of time, but the power meter does not have a structure to limit the sensor, which makes it inconvenient to disassemble, repair or replace the sensor, nor is it convenient to install the sensor.

The movement of the connecting rod 64 drives the limit rod 65 fixed thereto to move. When the limit rod 65 is completely slidably plugged into the limit hole on the outer wall of the mounting plate 51 on the same side, the motor 611 is turned off through the external PLC, and then several insertion strips 4 are slidably plugged into several slots on the top surface of the cover plate 2 respectively, and then the cover plate 2 and the power meter body 1 are fixed together by several screws, thereby completing the installation of the four sensor modules 5. According to the above, the four sensor modules 5 can be disassembled, repaired or replaced otherwise.
