[0002] Insulating oil is a mineral oil with good electrical insulation properties. In the process of producing insulating oil, it is often necessary to conduct a withstand voltage test on the insulating oil through a withstand voltage device to evaluate the quality of the insulating oil and ensure the safe operation of the power equipment.

[0024] The user pours the raw material into the oil cup 3, and then closes the observation door 2, allowing the test bench 5 to cooperate with the oil cup 3 to perform a pressure test on the raw material. At the same time, the user can observe the test effect of the raw material through the observation door 2. After the raw material test is completed, the second slider 403 moves the oil suction head 406 to the upper end of the oil cup 3, and then the cylinder 404 pushes the oil suction head 406 to move downward. After the oil suction head 406 is connected to the raw material, the external oil pump can extract the raw material through the oil suction pipe 407. At the same time, the cylinder 404 will control the oil suction head 406 to move downward slowly and cooperate with the oil pump to extract. After the raw material extraction is completed, the cylinder 404 drives the oil suction head 406 to move upward, and the second slider 403 drives the oil suction head 406 to reset.

[0025] Then the No. 1 slider 402 drives the fixed block 408 to move to the upper end of the oil cup 3, and then the cylinder 404 pushes the fixed block 408 to move downward, so that the fixed block 408 and the oil cup 3 are fitted together, and at the same time, the No. 1 connecting pipe 415 and the No. 2 connecting pipe 418 will enter the interior of the oil cup 3 respectively, and then the cleaning liquid can enter the interior of the No. 2 groove 410 along the water tank and the water guide pipe 412, and then the cleaning liquid entering the No. 2 groove 410 can also flow along the No. 2 connecting pipe 418, and at the same time, it is sprayed on the inner wall of the oil cup 3 through the through hole 419 for preliminary flushing, and then the external water pump will extract the flushing waste liquid in the oil cup 3 through the suction pipe 411, the No. 1 groove 409 and the No. 1 connecting pipe 415 to avoid leakage due to excessive liquid in the oil cup 3. The motor 416 drives the No. 1 connecting pipe 415 and the No. 2 connecting pipe 418 to rotate through the No. 2 connecting frame 417, so that when the No. 2 connecting pipe 418 rotates in conjunction with the through hole 419 to evenly rinse the oil cup 3, the No. 1 connecting pipe 415 and the No. 2 connecting pipe 418 drive the cleaning frame 420 to scrub the inner wall of the oil cup 3, thereby improving the cleaning efficiency and cleaning effect of the oil cup 3. After the cleaning is completed in the oil cup 3 and the waste liquid is completely discharged along the No. 1 connecting pipe 415, the cylinder 404 can pull the fixed block 408 to move upward to open the oil cup 3, and then the hot air blower 413 can be used to dry the inside of the oil cup 3 and the cleaning frame 420 to ensure that no water stains remain inside the oil cup 3, so that the oil cup 3 can be convenient for the storage test of the next batch of raw materials;

[0026] The No. 1 connecting pipe 415 and the No. 2 connecting pipe 418 are respectively connected with the engagement between the No. 1 groove 409 and the No. 2 groove 410, so that when the No. 1 connecting pipe 415 and the No. 2 connecting pipe 418 are rotating, the interior of the No. 1 groove 409 and the No. 2 groove 410 is always kept sealed, which can avoid leakage from the interior of the No. 1 groove 409 and the No. 2 groove 410, and also facilitate the water pump to extract the waste liquid in the oil cup 3 through the No. 1 groove 409 and the No. 1 connecting pipe 415;

[0027] The sealing block 414 is used to seal the fixed block 408 and the oil cup 3, so as to avoid leakage of the cleaning liquid in the oil cup 3 during the cleaning process, which is more convenient.

[0028] The working principle of a pressure-withstand device for insulating oil:

[0029] When in use, the user first pours the raw material into the oil cup 3, then closes the observation door 2, and allows the test bench 5 to cooperate with the oil cup 3 to perform a pressure test on the raw material. At the same time, the user can observe the test effect of the raw material through the observation door 2. After the raw material test is completed, the second slider 403 moves the oil suction head 406 to the upper end of the oil cup 3, and then the cylinder 404 pushes the oil suction head 406 to move downward. After the oil suction head 406 is connected to the raw material, the external oil pump can extract the raw material through the oil suction pipe 407. At the same time, the cylinder 404 will control the oil suction head 406 to move downward slowly and cooperate with the oil pump to extract. After the raw material extraction is completed, the cylinder 404 drives the oil suction head 406 to move upward, and at the same time, the second slider 403 drives the oil suction head 406 to reset.

[0030] Then the No. 1 slider 402 drives the fixed block 408 to move to the upper end of the oil cup 3, and then the cylinder 404 pushes the fixed block 408 to move downward, so that the fixed block 408 and the oil cup 3 fit together, and at the same time the No. 1 connecting pipe 415 and the No. 2 connecting pipe 418 will enter the interior of the oil cup 3 respectively, and then the cleaning liquid can enter the interior of the No. 2 groove 410 along the water tank and the water guide pipe 412, and then the cleaning liquid entering the No. 2 groove 410 can also flow along the No. 2 connecting pipe 418, and at the same time be sprayed on the inner wall of the oil cup 3 through the through hole 419 for preliminary flushing, and then the external water pump will extract the flushing waste liquid in the oil cup 3 through the suction pipe 411, the No. 1 groove 409 and the No. 1 connecting pipe 415 to avoid leakage due to excessive liquid in the oil cup 3, and at the same time the motor 416 will The connecting frame 417 drives the No. 1 connecting pipe 415 and the No. 2 connecting pipe 418 to rotate, so that when the No. 2 connecting pipe 418 rotates in conjunction with the through hole 419 to evenly rinse the oil cup 3, the No. 1 connecting pipe 415 and the No. 2 connecting pipe 418 will drive the cleaning frame 420 to scrub the inner wall of the oil cup 3, thereby improving the cleaning efficiency and cleaning effect of the oil cup 3. After the cleaning in the oil cup 3 is completed and the waste liquid is completely discharged along the No. 1 connecting pipe 415, the cylinder 404 can pull the fixed block 408 to move upward to open the oil cup 3, and then the hot air blower 413 can be used to dry the inside of the oil cup 3 and the cleaning frame 420 to ensure that no water stains remain inside the oil cup 3. After the cleaning of the oil cup 3 is completed, the user can pour the next portion of raw materials into the oil cup 3 and perform the test again.
