A high-voltage line connection device for water braking air circulation anti-flashover insulators

Abstract

The invention discloses a water brake gas circulation anti-flashover insulator high-voltage line connecting device which comprises an iron cap, a first umbrella skirt, a dust-proof and anti-flashoverzinc sleeve, a second umbrella skirt and a cotter pin. The iron cap is arranged on the upper surface of the first umbrella skirt and is connected with the first umbrella skirt by means of bonding. Thedust-proof and anti-flashover zinc sleeve is embedded in the bottom surface of the first umbrella skirt. The dust-proof and anti-flashover zinc sleeve is arranged on the second umbrella skirt and isconnected with the second umbrella skirt by means of welding. According to the invention, the amount of water in a water trap is slowly changed by slowing the memory rebound speed of a slow rebound pad; the buoyancy of a floating bag is changed, so that a blast tube is stretched or compressed; outside humid air is dried by a water absorbing and dehumidifying block; a pressure difference is formedthrough the branching of branch roads of a main road, so that dry air is ejected from the branch roads to produce a large impact force to clean dust accumulated under the second umbrella skirt; and aflashover accident caused by a conductive layer caused by the dissolving of damp dew, mist and a dirt layer is prevented.

Description

technical field [0001] The invention relates to the field of connecting devices for insulator high-voltage lines, more precisely, it relates to a device for connecting high-voltage lines of insulators with water brake and air circulation to prevent flashover. Background technique [0002] During the installation and connection of high-voltage lines, in order to increase the creepage distance, special insulation control insulators will be installed between the high-voltage lines and the wire connection tower for connection. Considering factors such as service life and price, most of them use double umbrella suspension insulators for connection. However, the existing traditional technology does not consider comprehensively, and has the following disadvantages: [0003] In the dry and windy north, due to the special umbrella-shaped structure of the umbrella-type insulator, it is easy to accumulate dust under the umbrella to form a dirty layer under the action of wind, but in ra...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a high-voltage line connection device for water braking air circulation anti-flashover insulators to solve the special umbrella-shaped structure of the umbrella-shaped insulator in the prior art in the dry and windy north. , under the action of wind, it is easy to make ash under the umbrella to form a dirty layer, but in rainy days, due to its umbrella-shaped structure, the rain cannot wash it away, and because of the large temperature difference between day and night in the north, it often forms fog. In addition, when it rains, the air with a large water content is driven by the flowing gas, and it is easy to enter under the umbrella and dissolve with the dirty layer to form a conductive layer, thereby causing a drop in flashover voltage, leading to flashover accidents, and affecting damage.
