This facilitates the assembly and disassembly of the sleeve 541 and the snap-fit ​​post 542.

[0031] like Figure 1 As shown, in one embodiment, a mounting cavity is formed inside the protective housing 1. A sealed door 12 is hinged to the protective housing 1 to control the opening and closing of the mounting cavity. The control module 4 is fixed inside the mounting cavity, and a power module 6, which is electrically connected to the detection module 2 and the alarm module 3, is also provided inside the mounting cavity. By providing the sealed door 12, the module inside the protective housing 1 is protected, and it also plays a certain role in dust prevention, which helps to extend the service life of the module.

[0032] like Figure 1As shown, in one embodiment, a first power connection structure 13 and a second power connection structure 14 are respectively provided on the two side walls of the protective housing 1. The first power connection structure 13 is electrically connected to the control module 4, and the second power connection structure 14 is electrically connected to the power module 6.

The power analyzer 21 is electrically connected to the control module 4 and the power supply module 6 via wires, respectively. The power transformer is electrically connected to the control module 4 via wires. Both the power analyzer 21 and the voltage transformer 22 are prior art and will not be described in detail here.

[0034] Preferably, the power analyzer 21 is a Gretel PPM88 model.

[0035] like Figure 1 As shown, in one embodiment, the alarm module 3 further includes a buzzer 32, the bottom of which is provided with a base for fixing to the wall, and the buzzer 32 is electrically connected to the control module 4 and the power module 6 respectively through wires.

[0036] like Figure 1 As shown, in one embodiment, the alarm mechanism further includes a wireless signal transmitter 7, which is electrically connected to the control module 4 via a wire; the protective housing 1 has multiple cable trays spaced apart for the wires to pass through. The wireless signal transmitter 7 is prior art and will not be described in detail here.

By providing the swing shaft 312, the swing of the swing shaft 312 on the bearing 311 allows the lamp tube 313 to adjust its installation angle, making it adaptable to different installation scenarios.

[0038] like Figure 3 As shown, in one embodiment, the lamp tube 313 is provided with three warning sections 3131 arranged sequentially, one above the other. The top warning section 3131 is provided with a red alarm light, the bottom warning section 3131 is provided with a green alarm light, and the middle warning section is provided with a yellow alarm light.

[0039] Working principle:

[0040] When the device is working, the detection connector 11 is connected to the power equipment under test, thereby using the power analyzer 21 to perform real-time detection of the power equipment and inputting the detected data into the control module 4. At the same time, the voltage transformer 22 detects the voltage in real time and feeds back the waveform, which is also input into the control module 4. The control module 4 processes the received voltage and power. When the voltage and power are within the normal value, the control module 4 controls the green alarm light to stay on. When the voltage and power slightly exceed the set limit value, the control module 4 controls the yellow alarm light to stay on and sends the value to the maintenance personnel's mobile phone through the wireless signal transmitter 7. When the voltage and power significantly exceed the set limit value, the control module 4 controls the red alarm light to flash and the buzzer 32 to sound an alarm, and the control module 4 sends the information to the maintenance personnel's mobile phone through the wireless signal transmitter 7.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
