Description

Technical Field

[0001] This utility model relates to the field of insulation withstand voltage testing technology, and in particular to an insulation withstand voltage testing mechanism for electrical components. Background Technology

[0002] In insulation resistance testing mode, an insulation withstand voltage testing apparatus for electrical components applies a stable DC voltage (typically between several hundred volts and several thousand volts, depending on the insulation class of the electrical component) to the electrical component through high-voltage electrodes. Simultaneously, a high-precision resistance measurement circuit measures the resistance value of the insulation components under this voltage.

[0003] The existing patent application with publication number CN217385704U uses an electric push rod to move the entire push plate downwards, thereby pushing the detection mechanism on one side of the movable plate downwards to detect the cells on the battery pack. When the detection mechanism contacts the battery pack, the movable plate slides upwards through the guide frame, thereby pushing the elastic telescopic rod to retract. When the elastic telescopic rod retracts, it cushions the entire movable plate, thereby cushioning the detection mechanism on one side of the movable plate. However, the insulation performance of the test equipment's outer shell is poor, which may lead to high voltage leakage and endanger the safety of the operators.

[0004] Therefore, it is necessary to provide an insulation withstand voltage testing mechanism for electrical components to solve the above-mentioned technical problems. Utility Model Content

[0040] The protective door 31 is movably embedded inside the front end of the machine tool 1, the sliding block 32 is fixedly connected to both ends of the inner surface of the protective door 31, and the fixing hole 33 is opened inside the sliding block 32.

[0041] The front end of the machine tool 1 has an opening, and the protective door 31 is slidably embedded in the opening. The surface is fitted with tempered glass and a handle, which facilitates observation of the internal condition of the machine tool 1 and makes it easy to pull the protective door 31. There are two fixing holes 33. A sliding groove is opened on the inner surface of the front end of the machine tool 1 near the left and right ends. The two fixing holes 33 are respectively fixedly connected to the left and right ends of the inner surface of the protective door 31 through the two sliding grooves. There are two fixing holes 33, and the two fixing holes 33 are respectively opened inside the two sliding blocks 32.

In each group, the sliding rods 41 are fixedly connected to the inner surfaces of the left and right ends of the machine tool 1.

The two sliding plates 43 are respectively sleeved on the outer surface of the sliding rods 41 in each group and connected to one end of the fixing springs 42. In each group, the two fixing blocks 44 are fixedly connected to the left and right ends of each sliding rod 41. Under the action of the elastic force of the fixing springs 42, the two front fixing blocks 44 can be respectively embedded in the two fixing holes 33 to fix the protective door 31.

[0044] The isolation plate 51 is fixedly connected to the inner surface of the machine tool 1, the sealing plate 52 is movably embedded inside the isolation plate 51, the hydraulic telescopic rod 53 is fixedly installed on the surface of the isolation plate 51, the connecting block 54 is fixedly connected to the bottom of the hydraulic telescopic rod 53, and the connecting block 54 is fixedly connected to the surface of the sealing plate 52.

[0045] The isolation plate 51 divides the interior of the two machine tools 1 into front and rear parts, and has an opening on its surface. The sealing plate 52 is slidably embedded in the opening. There are two hydraulic telescopic rods 53, which are fixedly installed on the left and right surfaces of the front end of the isolation plate 51. There are two connecting blocks 54. A sliding groove is opened on the left and right surfaces of the front end of the isolation plate 51. The two connecting blocks 54 are fixedly connected to the left and right surfaces of the front end of the sealing plate 52 through the two sliding grooves, and are also fixedly connected to the bottom of the two hydraulic telescopic rods 53. When the sealing plate 52 is sealed, the two connecting blocks 54 press the two fixed blocks 44 at the rear end, so that the fixing spring 42 is in a compressed state, thereby causing the fixing blocks 44 to disengage from the interior of the two fixing holes 33.

[0048] The working principle of the insulation withstand voltage testing mechanism for electrical components provided by this utility model is as follows:

[0049] First, pull the protective door 31 upward to place the electrical components on the movable seat 22. Then, close the protective door 31 and start the drive motor 23 to drive the threaded rod 21 to rotate. The movable seat 22 then moves backward. At this time, the hydraulic telescopic rod 53 is activated, pulling the sealing plate 52 upward through the connecting block 54. The isolation plate 51 is opened. During this process, the connecting block 54 moves upward and is no longer connected to the fixed block 44. The elastic force of the fixed spring 42 pushes the sliding plate 43 inward. The fixed block 44 is embedded in the fixed hole 33, and the protective door 31 is fixed. The movable seat 22 continues to move forward. After passing through the isolation plate 51, the hydraulic telescopic rod 53 pushes the connecting block 54 downward, causing the sealing plate 52 to move downward and seal the isolation plate 51. At this time, the connecting block 54 squeezes the fixed block 44, giving the fixed block 44 an outward pushing force. Through the sliding plate 43, the fixed block 44 embedded in the fixed hole 33 moves out of the fixed hole 33, and the protective door 31 loses its fixing force.

[0050] Compared with related technologies, the insulation withstand voltage testing mechanism for electrical components provided by this utility model has the following advantages:

[0051] This utility model provides an insulation withstand voltage testing mechanism for electrical components. A first protective component 3 and a second protective component 5 are respectively set at the front end and inside of the machine tool 1. When the sealing plate 52 is open, the protective door 31 can be fixed by the fixing component 4 to prevent the operator from accidentally opening the inside of the machine tool 1 and causing high voltage leakage. The two layers of protection increase the safety performance of the equipment.
