Technical Field

The utility model relates to an insulator technical field specifically discloses an extra-high voltage composite insulator.

Background

Insulators are devices that can withstand the action of voltage and mechanical stress, mounted between conductors of different electrical potentials or between a conductor and a grounded member. Insulators are various in types and shapes. Although the structures and the shapes of different types of insulators are greatly different, the insulators are composed of two parts, namely an insulating part and a connecting hardware fitting.

In the construction process of a high-voltage transmission project, in order to protect the transmission safety and ensure that each high-voltage transmission tower and each transmission cable are connected by virtue of an insulator, in the process of high-voltage transmission, when heavy rain weather is met, water flow can flow to the cable from the high-voltage transmission tower, impurities in air can be mixed when the rain falls, when the rain water is too large, continuous water flow can be caused to flow to the cable from the high-voltage transmission tower, high-voltage electricity of the cable is led into the high-voltage transmission tower by utilizing the water flow on the insulator, so that the high-voltage transmission tower is electrified to cause electric shock hazard, and sometimes, the situation that the high-voltage current breaks down the air to be led into the high-voltage transmission tower can occur, therefore, an inventor takes the consideration and inherits rich design development and practical manufacturing experience of the related industry for many years, researches and improves the existing structure and defects, and provides an, in order to solve the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve traditional insulator and can not effectively solve the problem that the transmission of electricity cable goes up the easy leading-in high voltage transmission tower of electric current.

In order to achieve the purpose, the basic scheme of the utility model provides an extra-high voltage composite insulator, which comprises an insulator body, wherein one end of the insulator body is provided with a first connector for connecting a high-voltage transmission tower, and the other end of the insulator body is provided with a second connector for connecting a transmission cable;

insulator body is close to first connector one end and is equipped with the water collector, and the opening of water collector is towards first connector, and water collector bottom surface intercommunication has the drain pipe of L type, and the drain pipe is including violently managing and standpipe, standpipe and water conservation dish intercommunication, and insulator body is close to second connector one end and is equipped with the current-collecting tray, and the length that the drain pipe was violently managed is greater than the radius of current-collecting tray.

The principle and effect of this basic scheme lie in:

1. the insulator is vertically arranged on the high-voltage transmission tower, and then the lower end of the insulator is connected with the transmission cable, so that in heavy rain weather, a large amount of water flow can flow to the transmission cable from the high-voltage transmission tower through the insulator body.

2. If the phenomenon that high-voltage current breaks through air appears below the insulator, when the high-voltage current breaks through the air upwards, the high-voltage current is blocked by the collecting disc, and the high-voltage current cannot be led into the high-voltage power transmission tower.

Compared with the prior art, the insulator can effectively solve the problem that high-voltage current appears in heavy rain weather is led into the high-voltage power transmission tower along with water flow, can also prevent the high-voltage current from breaking down air, is good in protection effect and is convenient to popularize and use on a large scale.

Furthermore, the one side of current collection dish towards the second connector is equipped with electrically conductive metal mesh. So as to intercept high-voltage current which breaks through air.

Further, a plurality of insulating umbrella skirt sheaths are sleeved on the insulator body. So as to block high-voltage current.

Further, a metal barb for preventing birds from nesting is arranged in the water receiving tray. Prevent birds from nesting in the water pan.

Furthermore, the water outlet of the drain pipe is provided with a drainage groove for increasing the water flow path. Effectively discharge rivers to the direction of keeping away from the insulator body.

Further, the conductive metal mesh is electrically connected with a grounding device. Effectively conduct away the high-voltage current which breaks through the air.

Detailed Description

The following is further detailed by the specific embodiments:

reference numerals in the drawings of the specification include: the insulator comprises a first connector 1, an insulator body 2, a water pan 3, a drain pipe 4, a current collecting pan 5 and a second connector 6.

An extra-high voltage composite insulator is disclosed, the embodiment is shown in fig. 1 and fig. 2, a first connector 1 for connecting a high voltage transmission tower is glued on the upper end of an insulator body 2, a second connector 6 for connecting a transmission cable is arranged on the gluing end of the lower end of the insulator body 2, a water pan 3 is glued on one end of the insulator body 2 close to the first connector 1, metal barbs for preventing birds from nesting are arranged in the water pan 3, the opening of the water pan 3 faces the first connector 1, the bottom surface of the water pan 3 is communicated with a vertical pipe of a drain pipe 4, a water outlet of the drain pipe 4 is connected with a drainage groove for increasing a flowing path, a current collecting pan 5 is glued on one end of the insulator body 2 close to the second connector 6, six insulating shed sheaths are uniformly glued on the part of the insulator body 2 where the water pan 3 and the current collecting pan 5 are not arranged, the length of the horizontal pipe of the drain pipe, the lower surface of the current collecting disc 5 is provided with a conductive metal net which is connected with a grounding device through a conductive cable.

When the heavy rain weather appears in normal high-voltage transmission, have a large amount of rivers that collect to flow to insulator body 2 from high-voltage transmission tower, these rivers will directly flow into water collector 3 after flowing into insulator body 2, then directly discharge from the sky through drain pipe 4 with 3 intercommunications of water collector, at this moment rivers just can no longer flow to transmission of electricity cable influence safety in utilization.

If the phenomenon that high-voltage current breaks through air appears below the insulator, when the high-voltage current breaks through the air upwards, the high-voltage current is blocked by the collecting disc 5, the high-voltage current which breaks through the air is firstly discharged from the grounding device through the electric conduction by the conductive metal net, and therefore the high-voltage current cannot be led into the high-voltage power transmission tower to affect the use safety.
