Abstract

The utility model provides an outdoor high voltage vacuum circuit breaker. Solid silicon rubber insulation medium is arranged in a cavity between an upper and a lower outlet arms; the cavity is formed by a vacuum arc-extinguishing chamber leaning against one end of the upper outlet arm and a ceramic sleeve; the solid silicon rubber insulation medium is used for blocking the creepage space. The solid silicon rubber insulation medium replaces nitrogen, SF6 gas, transformer oil or silicone oil insulating mediums in the prior art; thereby, the outdoor high voltage vacuum circuit breaker can generate oil leakage and gas leak phenomena when running. The utility model also has the advantages of reliable operation, long maintenance period, good environment protection effect, etc.

Description

Outdoor high-voltage vacuum breaker
The utility model relates to the High-Voltage Insulation architecture advances invention to the outdoor high-voltage vacuum breaker in the high pressure power transmission and distribution switchgear.
Current at China's farming, city power grid construction with in transforming, along with the increase of outdoor switch equipment, required outdoor high-voltage vacuum breaker also increases thereupon.Yet, the High-Voltage Insulation medium great majority that adopt between the insulator of existing outdoor high-voltage vacuum breaker and the vacuum interrupter are nitrogen, SF6 gas, transformer oil or silicone oil etc., these dielectrics are seepage As time goes on and gradually, thereby the outdoor high-voltage vacuum breaker maintenance cycle is short, need frequent maintaining, also pollute the environment simultaneously.
The purpose of this utility model provides a kind of outdoor high-voltage vacuum breaker that can not produce seepage and operation safety and reliability.
Outdoor high-voltage vacuum breaker described in the utility model comprises upper and lower outlet arm, vacuum interrupter, the insulator and the line that is flexible coupling; It is characterized in that between the upper and lower outlet arm of high-pressure vacuum breaker, by being provided with the firm silicone rubber dielectric in the vacuum interrupter of last outlet arm one end and the formed cavity of insulator.
The utility model is between upper and lower outlet arm; by in the vacuum interrupter of last outlet arm one end and the formed cavity of insulator the firm silicone rubber dielectric being set; to replace filling nitrogen, SF6 gas, transformer oil or the silicone oil dielectric that prior art was adopted; thereby make outdoor high-voltage vacuum breaker be in operation and can not produce leakage of oil, gas leak phenomenon; help environmental protection; and reliable, maintenance period is long.
Description of drawings the utility model embodiment:
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing 1 of the utility model the foregoing description, its electric loop is by last outlet arm 1, vacuum interrupter 4, soft tie 5 and following outlet arm 6 compositions.Vacuum interrupter 4 between last outlet arm 1 and following outlet arm 6 and insulator 3 formed cavity tops are provided with a firm silicone rubber dielectric 2 by last outlet arm 1 one ends, and it has been blocked along the creepage space of face, improve insulation property.When the outdoor high-voltage vacuum breaker operate as normal, circuit breaker is by last outlet arm 1, the normal conveying of electric loop part that vacuum interrupter 4, soft tie 5, following outlet folds in a garment 6 constitute; When circuit breaker is in gate-dividing state, moving in the vacuum interrupter 4, fixed contact separates, produce fracture, at this moment vacuum interrupter 4 two ends just produce potential difference, because vacuum interrupter 4 outer walls and insulator 3 inwall creepage distances are not enough, and condensation appears in outdoor products easily, filthy, make that insulation property reduce between fracture, if not adopting dielectric fills, just may produce flashover breakdown between insulator 3 inwalls and vacuum interrupter 4 outer walls, so be filled between vacuum interrupter 4 and the insulator 3 with firm silicone rubber, just can be so that the insulation property between the outdoor vacuum circuit breaker fracture improve, to reach the requirement of outdoor products to insulation.

Claims (1)
