[0016] like Figure 1 and Figure 2 As shown, a power monitoring device has a main body consisting of a power monitoring box 1;

[0017] The power monitoring box 1 is equipped with a main control switch 12, a wired power monitoring instrument 13, a sub-control switch A14-1 and a socket 15. The power monitoring box 1 is equipped with a fuse 16.

[0018] The main control switch 12, the wired power monitor 13, the fuse 16, the sub-control switch A14-1, and the socket 15 are connected in sequence to form a closed circuit A; the main control switch 12 is connected to an external power supply line 11 to energize the closed circuit A; the closed circuit A performs power detection on electrical components with plugs.

[0019] This utility model can measure the voltage, current, frequency, power consumption and cumulative power consumption of electrical equipment through a wired power monitoring instrument. It can measure different instruments as well as different data of the same instrument.

[0020] The wired power monitoring instrument can be of models such as P06s-20 and P06S-100.

[0021] Furthermore, the sub-control switch 14 is divided into sub-control switch A14-1, sub-control switch B14-2 and sub-control switch C14-3.

[0022] The power monitoring box 1 also includes a lamp holder 17 and a sub-control switch B14-2;

[0023] The main control switch 12, the wired power monitor 13, the fuse 16, the sub-control switch B14-2, and the lamp holder 17 are sequentially connected to form a closed circuit B; the closed circuit B performs power detection on the light bulb connected to the lamp holder 17.
