[0023] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0024] Combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 4, including; the main body 11; the main body 11 includes a bottom shell 1, an outer shell 2 and a control system 3; the control system 3 includes a lithium battery 301, a communication board 302, a test board 303, a liquid crystal display screen 304 and a power on / off button 305. The bottom shell 1 and the outer shell 2 are detachably connected. The front end of the bottom shell 1 is detachably connected with the lithium battery 301, the communication board 302 and the test board 303 in sequence through the mounting posts 4. The front end of the test board 303 is fixedly connected with the liquid crystal display screen 304 and the power on / off button 305. A panel is embedded inside the outer shell 2, and the panel is adapted to the test board 303. The top end of the bottom shell 1 is fixedly connected with a clamp-type current transformer 6. The number of the main bodies 11 is three groups, and the three groups of main bodies 11 are connected by Bluetooth signals. The panel is made of transparent plastic material. The power on / off button 305 penetrates through the panel and is slidably connected with it. Through the transparent material, the data change of the liquid crystal display screen 304 can be directly observed, and the power on / off button 305 can start and close the external control device. The connection between the bottom shell 1 and the outer shell 2 is sealed, and the connection between the bottom shell 1 and the panel is sealed. Through the sealing treatment, rainwater is prevented from entering the interior and affecting the device, increasing the safety performance. The three groups of main bodies 11 are connected through Bluetooth communication. The clamp-type current transformers 6 in the three groups of main bodies 11 are respectively in contact with three detection lines 14, and then the detection data of two groups of main bodies 11 are summarized into the main main body 11. The main body 11 transmits the data to the mobile phone or the background terminal, and the user analyzes the three-phase current situation monitored by the device through the mobile phone or the background reading device.

[0025] Combined with Figure 2 , Figure 3 and Figure 4 , a cooling mechanism 7 is provided inside the bottom shell 1. The cooling mechanism 7 includes two water tanks 701, a condensation pipe 702, a guide box 703 and a guide pipe 704. Two water tanks 701 are fixedly connected inside the bottom shell 1. The front surface of the bottom shell 1 is fixedly connected with the condensation pipe 702. The condensation pipe 702 is communicated with the two water tanks 701 through a water pipe 705. One end of the condensation pipe 702 away from the water tank 701 is fixedly connected with the guide box 703. Both sides of the guide box 703 are penetrated and communicated with the guide pipe 704. The water tank 701 and the guide pipe 704 are communicated through a guide hole 706. A water pump 12 is fixedly connected inside the water tank 701. The output end of the water pump 12 is communicated with the water pipe 705. A one-way valve 13 is fixedly connected to the outer side wall of the water pipe 705. The water pump 12 on one side conveys the coolant into the condensation pipe 702, then enters the guide box 703 and then re-enters the guide pipe 704 to complete the cooling cycle. The one-way valve 13 ensures the one-way conveyance of the coolant.

[0026] Combined with Figure 3 and Figure 4, a guiding mechanism 8 is provided in the guiding box 703. The guiding mechanism 8 includes a motor 801, a cam 802, a piston 803 and a linkage rod 804. The motor 801 is fixedly connected inside the guiding box 703, the output shaft of the motor 801 is fixedly connected with the cam 802, the piston 803 is slidably connected inside the guiding pipe 704, and a linkage rod 804 is rotatably connected between the cam 802 and the piston 803. A rubber pad 9 is slidably connected inside the guiding pipe 704. The rubber pad 9 is made of square rubber material. The outer side of the rubber pad 9 is in contact with the inner side of the guiding pipe 704. The rubber pad 9 has a certain elasticity and always contacts the inner wall of the guiding pipe 704 when descending under gravity, avoiding liquid leakage, thus facilitating the subsequent cooling effect. A condenser 10 is fixedly connected above the rubber pad 9. When the motor 801 drives the cam 802 to rotate, the piston 803 on one side is opened. At this time, the guiding box 703 is communicated with the guiding pipe 704, and thus enters the corresponding guiding pipe 704 for cooling.

[0027] Working principle: The three groups of bodies 11 are respectively contacted with the three detection lines 14, and then data monitoring is carried out. The two groups of bodies 11 summarize the detection data into the main body 11, and the body 11 transmits the data to the mobile phone or the background end. The user analyzes the three-phase current situation monitored by the device through the mobile phone or the background reading device.

[0028] During use, the water pump 12 on one side conveys the coolant into the condensing pipe 702, and then enters the guiding box 703. At the same time, the corresponding motor 801 in the guiding box 703 rotates 180 degrees to open the piston 803 on the other side. Thus, the guiding pipe 704 on this side is communicated with the guiding box 703, and the coolant is injected into the guiding pipe 704 to be cooled with the condenser 10, and at the same time, the rubber pad 9 is pressed to slide downward. The coolant is injected into the corresponding water tank 701 through the guiding hole 706. When pressing the rubber pad 9, the water pump 12 of the other water tank 701 works, and the two water pumps 12 work in a cycle to ensure sufficient time for cooling the coolant, thus avoiding the overheating of the device.
