Abstract

The invention relates to the technical field of electrics, in particular to a high-insulativity, high-precision and environment-friendly capacitive divider. The embodiment of the invention provides a plurality of self-healing type high-voltage capacitors with inner series structures and an outer shell, wherein the self-healing type high-voltage capacitors with the inner series structures are arranged in the outer shell, and the outer shell is filled with nitrogen gas; the series approaches among the self-healing type high-voltage capacitors with the inner series structures are arrayed in the outer shell in a cosine curve law. The embodiment of the invention can reduce the local discharge among capacitors and can reduce the size of the high-voltage capacitive divider.

Description

[0001] This application claims the priority of the Chinese patent application submitted to the China Patent Office on December 15, 2009, with the application number 200920292874.3, and the name is "Nitrogen Type High Insulation High Precision Environmental Protection Capacitive Voltage Divider", [0002] The entire contents of which are incorporated by reference in this application technical field [0003] The invention relates to the field of electrical technology, in particular to a high-insulation, high-precision, and environment-friendly capacitive voltage divider. Background technique [0004] The capacitive voltage transformer is a voltage transformer that extracts the medium voltage from a series capacitor, and then transforms it through a transformer as a voltage source for meters, relay protection, etc. The capacitive voltage transformer can also couple the carrier frequency to the transmission line for Long-distance communication, remote measurement, selective line...
