Abstract

The invention relates to a resistance-adjustable high-pressure water resistance device. The device comprises a water resistor, a water circulation mechanism for adjusting conductivity and an insulating tube, and the water inlet and the water outlet of the water circulation mechanism are respectively connected with two ends of the water resistor through the insulating tube to form a circulation path; during use, the insulating tube and the water resistor are at high potential, and the water circulation mechanism is at ground potential; the length of the insulating tube meets the formula that Lis larger than or equal to 1.5(2.8U-0.26U2+1.35U3), and L is the length of the insulating tube with the unit being m; U is the peak voltage of the connection point of the insulating tube and the waterresistance electrode, and the unit is MV. According to the device, the water resistor can be flexibly and conveniently applied to various high-voltage occasions, resistors of various voltage classesand resistance values can be provided for a laboratory, the purchasing cost input of the laboratory resistor is greatly reduced, the space utilization rate of the laboratory is increased, and the problems of poor stability and precision of the resistance value caused by long-time continuous high voltage are effectively solved.

Description

technical field [0001] The invention relates to the field of high-voltage testing, in particular to a high-pressure water resistance device with adjustable resistance. Background technique [0002] With the rapid development of large-capacity long-distance power transmission technology, the technological development of high-voltage power equipment has been promoted, and the quality inspection requirements for power equipment have been improved. The most direct and effective means of power equipment quality inspection is the high-voltage test. Through the performance test of the required voltage on various electrical products, electrical components, insulating materials, etc., the performance level of the product is assessed and the quality defects of the tested product are found. [0003] There are many types of high-voltage power equipment products, and the tests are different. In order to meet the high-voltage test needs of various products, the high-voltage laboratory nee...
