Abstract
The utility model relates to an insulating safe protective sleeve for a composite insulating zinc oxide lightning arrester. A sleeve body which is integrally made of silicone rubber is divided into two sections which comprises the protective string section and the protective end head section. An included angle is formed between the protective string section and the protective end head section. The end part of the protective end head section is expanded in a flying saucer shape, the bottom part of which is extended out of a circular protective enclosure. An axial lancing is arranged on the sleeve body. Both side edges of the sleeve body which is slit are both extended with a lateral wing which is connected with a hole. The utility model can be used for the insulating protective sleeve of the lightning arrester. A bare connection terminal can be completely and hermetically sheathed by the utility model which effectively prevents various accidents from occurring because of the bare terminal of an electric installation.
Description
The utility model relates to a kind of lightning arrester safety shield, belongs to electric power facility safety device field.
Along with State Grid's development and the construction of increasing urban and rural power grids are transformed, how to protect electric power facility better, guarantee safe power supply, more and more seem very important.
At present, a large amount of distribution transformers lack not only science but also safe and reliable serial safety device, and its electrical wiring termination is exposed outside.When take place the people for touch, stealing, toy or foreign material are made contact, when condensation dodges and situation such as irons, just can cause and damage electric power facility and electric shock casualty accident, reach the huge indemnity that causes thus.
In view of above-mentioned, the purpose of this utility model provides a kind of lightning arrester insulation safety shield, and it can protect exposed electric installation terminal stud, prevents that effectively all kinds of accidents that cause because of the electric installation terminal stud is exposed from taking place.
The purpose of this utility model is achieved through the following technical solutions:
A kind of compound inslation zinc oxide lightning arrester insulation safety shield, it is the body that is made into integration by silicon rubber, body is divided into and protects line segment and protect termination section two parts, protect line segment and protect between the section of termination and have angle, protect the end of termination section and expand into flying saucer shape, circular pad is extended in this flying saucer shape bottom, has an axial joint-cutting on the body, and the flank that has connecting hole is all extended in the both sides of the edge after cutting on the body.
Described joint-cutting also can be along protecting line segment and axially cuts the joint-cutting that protects line segment for axially cutting and protect line segment and axially cut and protect a joint-cutting of termination section along protecting the termination section along protecting line segment, or for axially cutting and protect the joint-cutting of termination section along protecting the termination section.
The described diameter that protects line segment outwards dwindles gradually.
The described angle that protects line segment and protect between the section of termination is the right angle.
The utility model advantage is: because after the utility model is placed on the electrical wiring termination, can avoid the electrical wiring termination exposed outside, because but the utility model adopts the silastic material of high insulation proof voltage 35KV, anti-aging, high-low temperature resistant, so can protect exposed electric installation terminal stud, prevent that effectively all kinds of accidents that cause because of the electric installation terminal stud is exposed from taking place, thereby guarantee the normal safe operation of electric power facility; Because the utility model can adopt out the structure of joint-cutting, so easy to install.
Describe in detail below in conjunction with drawings and Examples:
Fig. 1 is a contour structures schematic diagram of the present utility model, and Fig. 2 is the upward view of Fig. 1.
See also accompanying drawing 1,2.The utility model is the body that is made into integration by silicon rubber, and body is divided into and protects line segment 1 and protect termination section 2 two parts.Protect line segment 1 and protect between the termination section 2 having angle, this angle is generally the right angle.The diameter that protects line segment 1 outwards dwindles gradually.Protect the end of termination section 2 and expand into flying saucer shape 3, circular pad 4 is extended in these flying saucer shape 3 bottoms.Have on the body along protecting line segment 1 and axially cut and protect line segment 1 and axially cut and protect a joint-cutting of termination section 2 along protecting termination section 2.Flank 5 is all extended in both sides of the edge after cutting on the body, has many connecting holes 6 on the flank 5.Protect line segment 1 and be circle or non-circular with the cross section that protects termination section 2.
Building when installing on the electric power facility, only need sheath is broken into two with one's hands from the cutting section of body, protect line segment 1 with what binding post embedded body, the terminal stud of lightning arrester is embedded protecting in the termination section 2 of body, penetrate in each connecting hole 6 of two flanks 5 of body with pin at last, body can be connected into complete cover.This sample sheath is just lived the exposed complete big envelope of terminal stud.
It is the head of a nail, middle for the body of rod, the other end are the structure of cone that pin can adopt an end, makes the retaining step between the cone and the body of rod.
In other embodiment of the present utility model:
Consider manufacturing cost, can be on body only axially offer and cut the joint-cutting that protects line segment, or only axially offer to cut and protect the joint-cutting of termination section along protecting the termination section along protecting line segment.For example, joint-cutting is opened the bottom of protecting line segment 1 in diagram, during installation, to protect the terminal stud that termination section 2 is entangled lightning arrester earlier, treat binding post and lightning arrester electric connect finish after, again binding post is embedded and protect in the line segment 1, penetrate in each connecting hole 6 that protects 1 two flanks 5 of line segment with pin at last, body can be connected into complete cover.Again for example, joint-cutting is opened at the left part that protects termination section 2, during installation, line segment 1 part of protecting that body is not cut is placed on the binding post to the right, treat binding post and lightning arrester electric connect finish after, again with body to the Zola, make and protect the terminal stud that termination section 2 is entangled lightning arrester, penetrate in each connecting hole that protects two flanks of termination section 2 left parts with pin at last and get final product.But, this two example is not suitable for building sheath is installed on the electric power facility.
The utility model can be used as the insulating sleeve of lightning arrester electrical wiring termination, and the diameter that it protects line segment 1 and protects the angle between the termination section 2, the length of protecting termination section 2 and diameter and go up flying saucer shape part 3 needs to decide according to the specifications and models of lightning arrester.
More than narration and embodiment only are explanation the utility model; be not to be used for limiting claim of the present utility model; therefore; the improvement (protect line segment and protect angle between the section of termination etc. as change) of any unsubstantiality of doing based on the utility model and prior art surely belongs within the scope of patent protection of the present utility model.
