Dual-gas chamber direct-current voltage divider

Abstract

The present invention provides a dual-gas chamber direct-current voltage divider. The dual-gas chamber direct-current voltage divider comprises a high-voltage arm and a low-voltage arm connected in series through intermediate connecting conductors; the high-voltage arm is mounted in a cylindrical high-voltage arm housing having an insulating section; the upper end of the high-voltage arm is led out from the upper side of the insulating section; the intermediate connecting conductors extend out from the lower side of the insulating section; the lower end of the high-voltage arm housing is connected with a low-voltage arm housing which is used for sealing the low-voltage arm so as to isolate the low-voltage arm from the outside environment; two ends of the low-voltage arm are connected with voltage detecting conductors; the voltage detecting conductors extend out from the low-voltage arm housing; the intermediate connecting conductors are in insulating fit with the high-voltage arm housing and the low-voltage arm housing; and the voltage detecting conductors are in insulating fit the low-voltage arm housing. With the direct-current voltage divider of the invention adopted generation of parasitic resistance in parallel connection with the high-voltage arm can be avoided, and the accuracy of detection can be improved.

Description

technical field [0001] The invention relates to a double air chamber DC voltage divider. Background technique [0002] The DC voltage divider is mainly a resistance-capacitance DC voltage divider, which mainly includes a high-voltage arm and a low-voltage arm connected in series. The end of the high-voltage arm far away from the low-voltage arm is connected to the equipment, and the end of the low-voltage arm far away from the high-voltage arm is grounded. Through the high-voltage arm and The low-voltage arm divides the voltage of the equipment, and then detects the voltage on the low-voltage arm through the detection equipment, which can calculate the voltage of the equipment, reduces the requirements for the detection equipment, and makes the detection process safer. [0003] The high-voltage arm of the traditional DC voltage divider is installed in the cylindrical high-voltage arm shell, and the wires go out through the upper and lower ends of the cylindrical high-voltage...

Problems solved by technology

In the actual testing process, it is often found that there is a certain error between the equipment voltage calculated by the testing equipment and the actual equipment voltage. The existence of this error has caused great trouble to the testing personnel. How to eliminate this error has always been a problem.
