[0034] Reference Figure 1-6 , an intelligent detector used for electrical fault detection, in order to facilitate the placement of probes and connecting cords.

[0035] The intelligent detector comprises a housing 1, a probe 9, a winding reel 10, a fixing seat 8 and an elastic member 12;

[0036] The intelligent detector adopts a box-type packaging structure, which does not change the size, volume and layout of the internal modules, while taking into account the functions of fixation, integration, display and control. The entire shell adopts an integrated opening and closing design. The shell is divided into a shell 1 and an upper cover 2. The shell 1 is fixedly connected to the upper cover 2 by bolts. The integrated circuit board module is mainly arranged inside the shell. The inner bottom surface of the shell 1 is provided with a positioning column 102 to fix the circuit board module to prevent the internal module from scattering. In order to ensure that the detector is light and strong, a reinforcing rib 101 is designed inside the shell 1. The entire shell has a square appearance and an integrated design.

[0037] Since the intelligent detector is an instrument integrating partial discharge detection and display, a display screen 3 and openings for control buttons 5 are provided on the upper cover 2. At the same time, in order to prevent the instrument from being shut down by accident, an n-shaped protective plate 4 is designed for the power button in the opening area of ​​the control button to further improve the stability and durability of the partial discharge intelligent detector.

[0038] A cable 14 is provided on the electro-acoustic combined acquisition probe 9, and the cable 14 includes at least an acoustic signal line and an electrical signal line, and a metal braided layer is provided on the outside of the acoustic signal line and the electrical signal line, so that the acoustic signal line and the electrical signal line are combined into one line. The metal braided layer can prevent interference while enhancing the tensile strength of the cable. A socket 11 is provided on one side of the shell 1, and the socket 11 is electrically connected to the circuit board module. A plug is provided at one end of the cable 14, and the plug can be inserted into the inside of the socket 11, so that the cable 14 connects the electro-acoustic combined acquisition probe 9 with the circuit board module.

[0039] A fixed shaft is provided on one side of the shell 1, and the winding drum 10 is rotatably connected to the shell 1 through the fixed shaft. A handle is provided on the winding drum 10, and the winding drum 10 can be rotated by the handle, so that the cable 14 can be wound onto the winding drum 10 for retraction and release. The fixed seat 8 is fixedly connected to one side of the shell 1. The fixed seat 8 includes two fixed plates 801 and a fixed strip 802. The two fixed plates 801 are fixedly connected to one side of the shell 1, and the fixed strip 802 is fixedly connected between the two fixed plates 801. A card slot is provided on one side of the probe 9, and the card slot is adapted to the fixed strip 802. The elastic member 12 is fixedly connected to the upper surface of a fixed plate 801 at the bottom. The probe 9 can be inserted into the fixed seat 8, and when the probe 9 is inserted into the fixed seat 8, the fixed strip 802 will be inserted into the card slot, thereby limiting the probe 9. At the same time, since the elastic member 12 is a compression spring, it will squeeze the probe 9 inserted into the fixed seat 8 so that the probe 9 is pressed and fixed in the fixed seat 8.

[0040] A connection port 7 is designed on the top of the shell 1, and the connection port 7 includes a charging port, an expansion port and a USB interface. The charging port, the expansion port and the USB interface are all electrically connected to the circuit board module. The charging port can provide power to the partial discharge detector so that it can continue to work. The USB interface allows the data collected by the intelligent detector or the analysis results to be easily transmitted.

[0041] In addition, in order to facilitate the use of the intelligent detector;

[0042] The bottom of one side of the housing 1 is rotatably connected to a support leg 13. When the intelligent detector needs to be placed, the bottom support leg 13 can be rotated to open, and the support leg 13 can be rotated around the bottom of the intelligent detector by a certain angle, so as to support and place the intelligent detector (such as Figure 4 As shown), the support legs 13 can be folded up when not needed without affecting the appearance;

[0043] A magnet sheet slot 15 is provided at the back of the housing 1, and a magnet sheet can be pasted inside the magnet sheet slot 15, so that the intelligent detector can be directly adsorbed on the surface of the device to be tested and fixed by the magnet sheet.

[0044] A slide groove is provided on the top of one side of the shell 1, and a mounting plate 6 is slidably connected inside the slide groove. The mounting plate 6 is T-shaped, and a push block 601 is provided on one side of the mounting plate 6. A sliding hole is opened on one side of the slide groove, and the push block 601 can slide inside the sliding hole. When the smart detector needs to be fixed, the push block 601 can be pushed to push out the mounting plate 6 hidden inside the slide groove. There are mounting holes on the mounting plate 6, which facilitates the direct fixed installation of the smart detector.

[0045] The working principle of the intelligent detector is as follows: when conducting inspections, the staff can directly hold the intelligent detector in their hands. When the intelligent detector needs to be placed, the bottom support legs 13 can be rotated to open. The support legs 13 can rotate around the bottom of the intelligent detector at a certain angle, thereby supporting and placing the intelligent detector (such as Figure 4 As shown), the support legs 13 can be folded up when not needed, which does not affect the appearance. When the intelligent detector needs to be fixed, the magnet sheet can be pasted inside the magnet sheet slot 15, so that the intelligent detector can be directly adsorbed on the surface of the device under test for fixation through the magnet sheet, or the push block 601 can be pushed to push out the mounting plate 6 hidden inside the slide slot. The mounting plate 6 has mounting holes, so that the intelligent detector can be directly fixed and installed;

[0046] When the intelligent detector is testing, the cable 14 is directly pulled out from the retracted winding drum 10, and then the cable 14 plug is inserted into the socket 11, so that the cable 14 connects the electric and acoustic combined acquisition probe 9 with the circuit board module, and the detection can be performed through the probe 9 at this time;

[0047] After the detection is completed, when it is necessary to retract the probe 9 and the cable 14, first unplug the cable 14 plug from the socket 11, then rotate the winding reel 10 by the handle to reel all the cables 14 around the outside of the winding reel 10, and finally insert the probe 9 into the fixed seat 8. When the probe 9 is inserted into the fixed seat 8, the fixing strip 802 will be inserted into the card slot to limit the probe 9, making it easier for the probe 9 to be fixed inside the fixed seat 8. At the same time, the elastic member 12 will squeeze the probe 9 inserted into the fixed seat 8 upward, so that the probe 9 is pressed and fixed inside the fixed seat 8.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
