[0028] By placing the electrical equipment to be tested inside the closed assembly 2 and cooperating with the internal placement mechanism 3 to support the electrical equipment, the two ends of the closed assembly 2 can be quickly sealed, facilitating subsequent humidity adjustment inside the test cavity. With the above structure, the air in the internal cavity can be completely discharged after a single monitoring is completed and the internal test equipment is removed. Subsequent placement of the next electrical equipment inside can quickly achieve air replacement, thereby re-adjusting the humidity environment and avoiding mutual interference between different monitoring experiments.

[0029] Specifically, a cylindrical cavity is formed inside the closed assembly 2, and the middle partition plate 28 and the end partition plate 26 on the placement mechanism 3 are in contact with the inner wall of the closed assembly 2, thereby forming a sealed area inside the closed assembly 2.

[0034] The surface of the base 6 is used for locking and mounting the bottom of the fixed supporting plate 13, the movable sleeve 11 moves along the internal cavity of the sliding groove 7 through the movable supporting plate 14 at the bottom, the number of the extension plates 8 and the electric heating wires 9 is two, and the end of the placing mechanism 3 is located at the top of the electric heating wire 9 after being pulled out of the internal cavity of the closed assembly 2.

[0035] The placing mechanism 3 on the inner side can directly place the subsequent electrical equipment to be detected outside during the monitoring of the electrical equipment, and the switching process can be quickly completed when the two electrical equipments are replaced, so that the replacement efficiency in the monitoring process of different electrical equipments is improved, and the area of the placing mechanism 3 used after detection can be quickly drained and dried, so that the interference of the simulated humidity scene on the different monitoring environment conditions required subsequently is avoided.

[0036] Specifically, after the electrical equipment to be detected is moved to the placing plate 25, the placing mechanism 3 can be pushed along the inner convex strip 12 on the inner wall of the closed assembly 2 until the entire electrical equipment to be detected is pushed into the internal cavity of the closed assembly 2, and the sealing of the internal cavity of the closed assembly 2 can be realized by the end partition plates 26 and the middle partition plates 28 at both ends of the placing plate 25.

[0037] In the embodiment, the lead-in assembly 4 and the lead-out assembly 5 each comprise: The guide sleeve 33 is internally provided with the telescopic rod 39, the guide sleeve 33 is integrally provided with the connecting rod 34 on the side, the other end of the connecting rod 34 is integrally provided with the threaded sleeve 35, the threaded sleeve 35 is internally provided with the threaded rod 36, the outer side of one end of the threaded rod 36 is provided with the knob 37, and the threaded rod 36 moves linearly in the threaded sleeve 35.

[0038] The import component 4 and export component 5 also include: The cable 41, rotating ring 31, retaining strip 32, pressing plate 38, and conductive probe 40 are provided.

[0039] Inside the enclosed component 2 are an inlet component 4 and an outlet component 5 for conductivity testing. Together with the columnar structure of the enclosed component 2 itself, it can provide contact conductivity between any two locations on the surface of electrical equipment of different types and specifications, thus expanding the scope of application. It provides the functions of translation and rotation angle adjustment, without interfering with the movement and rotation of the internal placement mechanism 3.

[0040] Specifically, after the placement mechanism 3 is pulled out, the entire placement plate 25 is rotated by pulling the lever 29. At this time, the placement plate 25, as well as the end partitions 26 and the middle partition 28 at both ends of the placement plate 25, will rotate through the central pivot 30, thereby rotating the top surface of the placement plate 25 to face the bottom. In this state, the water adhering to the placement plate 25 can be accelerated to flow downward. With the help of the electric heating wire 9 on the extension plate 8, the surface moisture of the placement plate 25 after the test can be quickly dried. Moreover, the rotation process is always outside the closed assembly 2, so it will not affect the state of the placement plate 25 that is moved into the closed assembly 2. Therefore, the process of removing the electrical equipment under test, drying, and re-placing the electrical equipment under test after removal can be carried out synchronously with the testing process of the electrical equipment under test inside the closed assembly 2.
