Abstract

The invention relates to a high-pressure water resistance device with adjustable resistance. The device includes a water resistance and a water circulation mechanism for adjusting conductivity. The device also includes an insulating tube. The water inlet and outlet of the water circulation mechanism pass through the insulating tube. They are respectively connected to both ends of the water resistance to form a circulation path; when in use, the insulating tube and the water resistance are at high potential, and the water circulation mechanism is at ground potential; the length of the insulating tube satisfies the formula: L≥1.5(2.8U‑0.26U 2 +1.35U 3 ), where: L is the length of the insulating tube, in m; U is the peak voltage at the connection point between the insulating tube and the water resistance electrode, in MV. The device of the present invention can make water resistors flexibly and conveniently applied to various high-voltage occasions, can provide laboratories with resistors of various voltage levels and resistance values, greatly reduce the cost of laboratory resistor procurement, and increase the utilization rate of laboratory space , which effectively solves the problem of resistance stability and poor precision caused by long-term continuous high voltage.

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...
