Abstract

The utility model belongs to an AC phase change conductor in a tank body assembled by a porcelain bushing. The conductor mainly comprises a basin-shaped insulating body. The lower ends of an A-phase conductor, a C-phase conductor and a middle-phase conductor are in triangular layout and are positioned on the basin-shaped insulating body, wherein the A-phase conductor, the C-phase conductor and the middle-phase are arc-shaped and bent; and the upper end of the A-phase conductor is positioned above the lower end of the C-phase conductor, the upper end of the C-phase conductor is positioned above the lower end of the A-phase conductor, and the upper end of the middle-phase conductor is positioned in the middle point between the A-phase conductor and the C-phase conductor at the upper end of the middle-phase conductor. On the premise that interphase insulating property is ensured, the AC phase change can be crosswise realized in the tank body assembled by the porcelain bushing, so that the conductor provided by the utility model has the advantages of compact structure, stable property, small volume, low cost, simplicity and labor conservation in construction, and good operating safety.

Description

Insulator assembling AC commutation conductor

Technical field

The utility model belongs to a kind of insulator assembling AC commutation conductor.

Background technology

In the actual engineering of case GIS, can run into the operating mode that turnover line side AC needs commutation altogether, the operating mode of turnover line side AC commutation is usually owing to complex structure, and volume is big, and can not realize in the tank interior of insulator assembling.This volume that has not only influenced the GIS circuit breaker increases, and is loose, significantly increased its manufacturing cost, and makes installation trouble effort, equipment operation poor stability.Along with the high voltage switchgear trend of miniaturization and high parameterization day by day, electric power system is also more and more higher to the requirement of high voltage switchgear reliability, presses for a kind of compact conformation at present, volume is little, cost is low, and it is simply laborsaving to construct, the AC commutation device that safety in operation is good.

Summary of the invention

The purpose of this utility model is a kind of insulator assembling of design AC commutation conductor, under the prerequisite that guarantees alternate and insulation property, can realize the commutation of AC intersection in the tank interior of insulator assembling, has compact conformation, stable performance, volume is little, and cost is low, it is simply laborsaving to construct, the advantage that safety in operation is good.

For this reason, the utility model mainly is made up of the benzvalene form insulator.The lower end of A phase conductor, C phase conductor and middle phase conductor is angular distribution and is located on the benzvalene form insulator, A phase conductor, C phase conductor and the middle phase conductor shape that is convexly curved, the upper end of A phase conductor is positioned at the space on top, C phase conductor lower end, the upper end of C phase conductor is positioned at the space on top, A phase conductor lower end, and the upper end of middle phase conductor is positioned at the space of A, top, C phase conductor upper end mid point.Said structure has reached the purpose of this utility model.

The utility model can be realized the commutation of AC intersection in the tank interior of insulator assembling under the prerequisite that guarantees alternate and insulation property, have compact conformation, stable performance, and volume is little, and cost is low, and it is simply laborsaving to construct, the advantage that safety in operation is good.
