[0002] Electric equipment is an electric device that uses electromagnetic energy to complete certain functions, and mainly includes power generation equipment, power transmission and transformation equipment, power utilization equipment, power electronic equipment, electromagnetic measuring instruments and the like. Insulation performance detection of electric equipment is mainly to evaluate the ability of insulation materials and insulation structures of electric equipment to prevent current from passing under normal operation and various expected overvoltages, so that defects of insulation, such as insulation aging, dampness and local damage, can be found through detection, and electrical faults such as short circuit and electric leakage caused by insulation failure can be avoided, thereby ensuring the safety of equipment and personnel. In order to ensure the quality of electric equipment, insulation performance detection of electric equipment is required after the production and manufacturing of electric equipment are completed, and an insulation resistance tester is usually used. Two or three detection terminals on the insulation resistance tester are connected with electric equipment, a direct current voltage is generated by using a direct current high-voltage generator and is applied to the measured object, a measuring circuit measures the current flowing through the measured object, and the insulation resistance value is calculated according to Ohm's law. Advanced digital processing technology and nonlinear elements are usually used in the insulation resistance tester to realize accurate measurement of different resistance values.

[0003] In the related art, although the insulation resistance tester can meet the basic requirement of detecting the insulation performance of electric equipment, it is found in actual use that there are at least the following deficiencies: The insulation resistance tester mostly needs to be held by an operator to detect the insulation performance of electric equipment, which is time-consuming and laborious, and since the three detection terminals on the insulation resistance tester have a certain length, they are prone to entangle with each other during detection, which affects the convenience of operation and work efficiency.

[0025] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] See Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides an IoT-enabled electrical equipment insulation performance testing device, including a testing platform 1. A shelf 2 for supporting the electrical equipment is fixedly installed on the top of the testing platform 1. A hanging rack 3 is located on the top of the testing platform 1, and an insulation resistance tester 4 is detachably mounted on the hanging rack 3. The insulation resistance tester 4 is used to test the insulation performance of the electrical equipment. A display screen 5 and adjustment buttons 6 are provided on the front of the insulation resistance tester 4. Three test connectors 7 are plugged into the front of the insulation resistance tester 4. A metal clip 8 is fixedly installed at one end of each of the three test connectors 7. The metal clip 8 can stably clamp the corresponding test points of the electrical equipment, ensuring the reliability of the connection during the testing process and ensuring the accuracy of the test data. It should be noted that the three test connectors 7 are respectively a line terminal, a grounding terminal, and a shielding terminal. For example, to measure the insulation resistance between a motor winding and its casing, the line terminal is connected to the lead-out end of the motor winding, and the grounding terminal is connected to the motor casing, thus establishing a measurement circuit, enabling the instrument to measure the insulation resistance from the winding to the casing. For example, to measure the insulation resistance between the motor winding and its casing... When testing the insulation resistance of a cable, for a single-core cable, the line terminal is connected to the cable core, and the grounding terminal is connected to the cable's metal shield or armor layer. If the cable's insulation sheath is damp, it may affect the accuracy of the measurement results. In this case, a shielding terminal can be used, connecting it to the insulation layer between the cable's insulation sheath and the metal shield. This reduces the impact of surface leakage current on the measurement results. When testing the insulation performance of electrical equipment, the connection method of the three test connectors 7 is a conventional technique in this field, and therefore will not be described in detail here. One side of the insulation resistance tester 4 is electrically connected to a wireless communication module 9. The wireless communication module 9 is used to wirelessly transmit the test data of the insulation resistance tester 4 to a terminal device. The terminal device can be any of a mobile phone or computer, thus enabling remote reception and access to the insulation performance test data results. This allows testing personnel to view and analyze data in real time on a remote terminal device without having to read the data directly near the testing machine 1, facilitating collaborative testing by multiple people and centralized processing and storage of large amounts of test data.

[0027] The mounting bracket 3 includes a vertical plate 301, a telescopic plate 303, a spring 304, an L-shaped clamping plate 305, and an L-shaped support plate 306. The vertical plate 301 is fixedly installed on the top left side of the testing machine base 1. A groove 302 is formed on the top of the vertical plate 301. The bottom of the telescopic plate 303 is slidably installed in the groove 302. The bottom end of the spring 304 is fixedly connected to the bottom inner wall of the groove 302, and the top end of the spring 304 is fixedly connected to the bottom of the telescopic plate 303. The L-shaped clamping plate 305 is fixedly installed on the top of the telescopic plate 303. The L-shaped support plate 306 is fixedly installed on the right side wall of the vertical plate 301. The insulation resistance tester 4 is located between the L-shaped support plate 306 and the L-shaped clamping plate 305, utilizing the spring 304. The elastic force of the L-shaped clamp 305 and L-shaped support plate 306 adjusts the distance between them, thus stably clamping and hanging the insulation resistance tester 4. This eliminates the need to hold the insulation resistance tester by hand for insulation performance testing of electrical equipment, making it more convenient and the testing operation smoother. Anti-slip pads 307 are fixedly installed on the sides of the L-shaped support plate 306 and L-shaped clamp 305 that are close to each other. The two anti-slip pads 307 abut against the top and bottom of the insulation resistance tester 4, respectively. The anti-slip pads 307 increase the friction when clamping the insulation resistance tester, preventing the insulation resistance tester 4 from shifting during the testing process, further improving stability and safety.

[0028] In this embodiment, three sets of cable management racks 10 are provided on the hanging frame 3. The cable management racks 10 are used to limit the position of the test connectors 7, which can prevent the three test connectors 7 from getting tangled together, making the operation of testing the insulation performance of electrical equipment more convenient and smooth. The cable management rack 10 includes a fixed base 101, a rotating base 103, a rotating shaft 104, a damping telescopic rod 105, an elastic limiting ring 106, and two elastic retaining balls 107. The fixed base 101 is fixedly installed on the bottom of the L-shaped support plate 306. The fixed base 101 has an installation cavity 102. The rotating base 103 is rotatably installed in the installation cavity 102. The rotating shaft 104 is fixedly installed on the bottom of the rotating base 103. A through hole is opened on the bottom inner wall of the installation cavity 102. The bottom end of the rotating shaft 104 passes through the through hole. The damping telescopic rod 105 is fixedly installed on the bottom end of the rotating shaft 104. The elastic limiting ring 106 is fixedly installed on the bottom of the rotating base 103. At the telescopic end of the damping telescopic rod 105, two elastic locking balls 107 are embedded in the outer side wall of the rotating seat 103 and are symmetrically distributed. Multiple arc-shaped slots 108 are opened on the inner side wall of the mounting cavity 102. The multiple arc-shaped slots 108 are arranged in an evenly spaced ring. The two elastic locking balls 107 slide and abut against the corresponding arc-shaped slots 108. The position of the elastic limiting ring 106 can be adjusted by utilizing the telescopic feature of the damping telescopic rod 105, thereby limiting the detection connector 7 to a suitable position for use. The rotating seat 103 can be fixed at different angles by the locking cooperation of the elastic locking balls 107 and the arc-shaped slots 108, thereby adjusting the orientation of the elastic limiting ring 106. It should be noted that the elastic locking balls 107 can be made of elastic rubber or silicone. The number of arc-shaped slots 108 is not less than two and the number is set to be even.

[0029] In this embodiment, limit grooves are provided on both inner walls of the groove 302, and limit blocks are fixedly installed on both bottom sides of the telescopic plate 303. The two limit blocks are slidably installed in the corresponding limit grooves to limit the sliding stroke of the telescopic plate 303.

[0030] In this embodiment, a bearing 109 is fixedly mounted on the rotating shaft 104, and the outer ring of the bearing 109 is fixedly connected to the inner wall of the through hole.

[0031] In this embodiment, the elastic limiting ring 106 has an opening on the side away from the damping telescopic rod 105. The opening design of the elastic limiting ring makes it convenient to include the detection connector 7 for limitation. The elastic limiting ring 106 can be made of insulating materials such as plastic with good elasticity.

[0032] In this embodiment, a buffer pad 11 is fixedly installed on the top of the shelf 2. The cross-sectional dimensions of the buffer pad 11 are the same as those of the shelf 2. When electrical equipment is placed, the buffer pad 11 can effectively reduce the impact force between the electrical equipment and the shelf 2 caused by the placement action, prevent the electrical equipment from being damaged by collision, and extend the service life of the electrical equipment.

[0033] Based on the above structure, the working principle of the IoT-enabled electrical equipment insulation performance testing device provided in this application is as follows:

[0034] By pulling the L-shaped clamp 305 upwards, the L-shaped clamp 305 drives the telescopic plate 303 to slide vertically upwards. At this time, the spring 304 is stretched and generates elastic force. When the distance between the L-shaped clamp 305 and the L-shaped support plate 306 is adjusted to be greater than the height of the insulation resistance tester 4, the insulation resistance tester 4 can be placed on the anti-slip pad 307 on the L-shaped support plate 306. Then, the L-shaped clamp 305 is released. Under the elastic force of the spring 304, the telescopic plate 303 and the L-shaped clamp 305 can be controlled to move downwards, so that the anti-slip pad 307 on the L-shaped clamp 305 is pressed tightly against the top surface of the insulation resistance tester 4. This completes the stable fixing and hanging operation of the insulation resistance tester 4. In subsequent testing operations, it is not necessary to hold the insulation resistance tester 4.

[0035] Next, insert the three test connectors 7 into the openings of the corresponding elastic limiting rings 106. At this time, the three elastic limiting rings 106 can be used to position the corresponding test connectors 7 respectively, thereby preventing the three test connectors 7 from getting tangled together during subsequent testing and use.

[0036] After the above preparations are completed, place the electrical equipment to be tested on the buffer pad 11 on the shelf 2. By rotating one of the rotating shafts 104, the rotating shaft 104 drives the rotating seat 103 at its top to rotate. The two elastic retaining balls 107 on the outer wall of the rotating seat 103 cooperate with the arc-shaped retaining groove 108 on the inner wall of the mounting cavity 102, so that the rotating seat 103 can be fixed at different angles, thereby achieving the function of adjusting the orientation of the elastic limiting ring 106. The position of the elastic limiting ring 106 can be adjusted by utilizing the telescopic feature of the damping telescopic rod 105, thereby limiting the test connector 7 to the required position. According to the above operation steps, the three test connectors 7 can be limited to their respective required positions in sequence according to the operation requirements.

[0037] Then, the three metal clips 8 can be clamped onto the corresponding testing positions of the electrical equipment, and the insulation resistance tester 4 can be turned on to perform the insulation performance test. During the test, the test data of the insulation resistance tester 4 can be wirelessly transmitted to the terminal device through the wireless communication module 9, and the data results of the insulation performance test can be received remotely.
