Detailed Description
The shell 9 is placed on a plane near a high-voltage power supply to be aged, DN15 copper cooling water pipe 2 is arranged on the inner wall of the shell 9 in a surrounding mode, the cooling water pipe 2 at the right angle of the inner wall of the shell 9 turns with the bending radius of 10 centimeters, and the two ends of the cooling water pipe 2 are respectively connected with a cooling water inlet 3 and a cooling water outlet 1. The cooling water inlet 3 is arranged at the lower part of the outer wall of the shell 9, and the cooling water outlet 1 is arranged at the upper part of the outer wall of the shell 9. The outer surface of the shell 9 is provided with cooling fins 10. The upper cover plate 5 is made of transparent acrylic plates, and the upper cover plate 5 is provided with a high-voltage socket 4. A polytetrafluoroethylene support 7 is arranged on a bottom plate of the shell 9 along the central line of a long edge, the width and the height of the support 7 are respectively 15 cm and 25 cm, and U-shaped grooves are formed in the top surface of the support 7 along the long edge direction at intervals of 20 cm. The resistors 6 are placed in the U-shaped grooves, the resistors 6 are connected end to end in series through conducting wires to form resistor groups, the outer layers of the conducting wires are sleeved with polytetrafluoroethylene tubes, after the polytetrafluoroethylene tubes are led out from the connecting terminals of the resistors 6, the distance between the polytetrafluoroethylene tubes and the resistors is kept at 10 cm, and the resistance values of the resistor groups can be adjusted according to the high voltage and different loads. The two ends of the resistor 6 keep a distance of 20 cm from the four walls of the shell 9, and the head and the tail ends of the resistor group are respectively connected to the two poles of the high-voltage socket 4 by electrode leads 8. No. 45 transformer oil is injected into the shell 9, and the oil level does not exceed the resistance 6 by more than 20 cm. The output end of the high-voltage power supply is respectively connected to two poles of a high-voltage socket 4 of the device. The cooling water pipe 2 is internally filled with circulating cooling water.
For a high-voltage power supply with 200 kilovolts of high-voltage output and 4 kilowatts of power output, 5 resistors 6 of 2 megaohms are connected in series to form a resistor group for a load. The output end of the high-voltage power supply is respectively connected to two poles of a high-voltage socket 4 of the aging device. And (3) cooling water is introduced from a cooling water inlet 3 and is output from a cooling water outlet 1 after passing through a cooling water pipe 2. The high voltage power supply is started, the power supply voltage is gradually increased to 200 kilovolts, and the high voltage state in the device can be directly observed through the transparent upper cover plate 5. Because the inside is filled with insulating oil, the corona phenomenon is eliminated. If the ignition is directly observed through the transparent upper cover plate 5, whether the ignition is caused by the high-voltage power supply or a load aging device is judged. If the load aging device causes the aging, the high-voltage power supply can be turned off, the distance between ignition points is increased, the high-voltage power supply is turned on again, the ignition phenomenon is eliminated, and the aging is continued. If the high-voltage power supply instrument displays the ignition fault and the load aging device does not observe the fault, the phenomenon of ignition occurs in the high-voltage power supply equipment. The heat generated by the resistor 6 under high voltage is uniformly transferred to the cooling water pipe 2 on the inner wall of the shell 9 and the radiating fins 10 on the outer wall by the insulating oil, and the generated heat is taken away in time. And when the high-voltage power supply is aged, the high-voltage power supply is closed, the output end is detached from the high-voltage socket 4, and the cooling water is closed. In order to keep the insulating oil with good insulating effect, the insulating oil should be filtered at certain intervals to filter out the moisture inside.
