Insulating sleeve of outdoor pole-mounted double voltage sensors

Abstract

The invention relates to an insulating sleeve of outdoor pole-mounted double voltage sensors. The insulating sleeve comprises an insulating sleeve body, a vacuum arc extinguishing chamber, a first voltage sensor and a second voltage sensor, wherein the vacuum arc extinguishing chamber is arranged on the upper part in the insulating sleeve body; the first voltage sensor and the second voltage sensor are positioned on the inner wall of an insulating layer of the insulating sleeve body and have an integrated structure with the insulating sleeve body; a first collection head is arranged on the top of the inner side of a power incoming line of the insulating sleeve body and is connected with the first voltage sensor; the first voltage sensor outputs through a first signal line; one end of a power outgoing line of the insulating sleeve body is provided with a second collection head; the second collection head is connected with the second voltage sensor; and the second voltage sensor outputs through a second signal line. The insulating sleeve can have the original functions and has the technical requirements of voltage detection so as to substitute the independent voltage sensor.

Description

technical field [0001] The invention relates to the technical field of vacuum circuit breakers, in particular to an insulating sleeve of a dual voltage sensor on an outdoor pole. Background technique [0002] Because of its reliable high voltage isolation function and good detection performance, voltage sensors have been widely used in electrical equipment in urban and rural power grids. When the independent pillar-type voltage sensor is manufactured, the capacitive pressure-dividing sensor element is wrapped with epoxy resin and then solidified (see image 3 ), resulting in a post-type insulator-like finished product, installed in a vacuum circuit breaker (see figure 1 ) or transmission and distribution line network, the unfavorable factors such as the large number of independent voltage sensors, large volume, high cost, and cumbersome installation have become practical problems that need to be dealt with. Nowadays, the miniaturization, low cost, material saving and envir...
