Description

A kind of GIS SF6Gas leakage location insulating tape

Technical field

The present invention relates to power system service technique field, particularly relate to a kind of GIS SF₆Gas leakage location insulating tape. Specifically SF in a kind of GIS₆Instrument during gas leakage, leakage point positioned, it can position SF economical, convenient, efficiently, intuitively₆Gas leakage point.

Background technology

GIS refers to sulfur hexafluoride sealed combination electrical equipment, is called that " Cubicle Gas-Insulated Switchgear " (GasInsulatedSwitchgear) is called for short GIS in the world. GIS is filled with the SF higher than 4-8 times of atmospheric pressure₆Gas, gas leakage is one of most common failure. At present, detection SF₆The main method of gas leakage has infrared imaging method, soap bubble method, vacuumizing method etc. All there is certain limitation in these methods: although infrared imaging method is directly perceived, but price is sufficiently expensive, is not suitable for popularity, and by GIS structure influence, the concrete leakage point of concealment part is not easily watched. Although soap bubble method, vacuumizing method are economical, but complex operation, locating effect is extreme difference also. Instant invention overcomes above-mentioned whole shortcoming, both economical convenient, efficiently directly perceived again, not by GIS structure influence. When suspecting that disc insulator has leakage, the present invention can quickly locate leakage point.

Summary of the invention

The present invention overcomes existing middle technology Problems existing, it is provided that a kind of GIS SF₆Gas leakage location insulating tape, is suitable for scene and quickly locates SF₆Gas leakage point, economic light instrument intuitively convenient, efficient.

The technical solution used in the present invention is:

A kind of GIS SF₆Gas leakage location insulating tape, including polyvinylidene fluoride transparent plastic, two-layer PE foam and ultra-thin fragile paper; Being stained with passive upper strata PE foam below described polyvinylidene fluoride transparent plastic, lower floor's PE foam is fixed on GIS disc insulator; It is provided with ultra-thin fragile paper between upper strata PE foam and lower floor's PE foam.

Described PE foam is the white PE foam that characteristic is soft.

Described lower floor's PE foam is equipped with up and down: adhering agent layer that is that play fixing ultra-thin fragile paper respectively and that leak the effect being fixed on disc insulator when positioning.

Described ultra-thin fragile paper has certain crimpiness, and when fractureing, section energy ecto-entad is curling.

The outside of described ultra-thin fragile paper is white, and the inside is red.

The upper sheaf space of described ultra-thin fragile paper has certain tiny structure, and ultra-thin fragile paper can bear the pressure differential of external atmosphere pressure and internal tiny structure.

Described polyvinylidene fluoride transparent plastic is a kind of transparent plastic for polyvinylidene fluoride.

Described PE foam is continuously " mouth " character form structure.

There is the SF of the present invention of said structure feature₆Gas leakage location insulating tape, compared with having technology with oneself, has the advantage that

(1) SF of the present invention₆The ultra-thin fragile paper of gas leakage location insulating tape inside and outside different colours, when location it is clear that efficiently directly perceived.

(2) SF of the present invention₆The gas leakage location material that uses of insulating tape is all ep-type material, will not to environment, and cheap, make finished product price also particularly economical.

(3) SF of the present invention₆Gas leakage location insulating tape is easy to operate, just as every day use transparent rubberized fabric, doubtful leak is pasted, convenient and swift.

Below in conjunction with the drawings and specific embodiments, the present invention is done further detailed description.

Accompanying drawing explanation

Fig. 1 is present configuration schematic diagram;

Fig. 2 is the outward appearance front view of Fig. 1;

Fig. 3 is the outside side view of Fig. 1.

In figure: polyvinylidene fluoride transparent plastic 1, upper strata PE foam 2, lower floor's PE foam 3, ultra-thin fragile paper 4.

Detailed description of the invention

By Fig. 1-Fig. 3 it can be seen that the present invention is a kind of GIS SF₆Gas leakage location insulating tape, is mainly made up of polyvinylidene fluoride transparent plastic 1, two-layer PE foam and ultra-thin fragile paper 4.

Described polyvinylidene fluoride transparent plastic 1 is a kind of material is the transparent plastic of polyvinylidene fluoride, it is similar to transparent rubberized fabric, it is stained with upper strata PE foam 2 below, upper strata PE foam 2 plays a supportive role, and makes polyvinylidene fluoride transparent plastic 1 stick to above the upper strata PE foam 2 of " mouth " font continuously.

Described PE foam color is white, and characteristic is soft, point upper and lower two-layer. Upper strata PE foam 2 plays a supportive role, and lower floor's PE foam 3 acts the effect being fixed on GIS disc insulator. Lower floor's PE foam about 3 is equipped with adhering agent layer, the effect being fixed on disc insulator when playing effect and the leakage location of fixing ultra-thin fragile paper 4 respectively.

Described ultra-thin fragile paper 4 is the core of insulating tape, between PE foam, is the critical component of leak point positioning. Ultra-thin fragile paper 4 has certain crimpiness, and when fractureing, section energy ecto-entad is curling. Being white outside it, the inside is red, is to can substantially find when location. The upper sheaf space of ultra-thin fragile paper 4 has certain tiny structure, and ultra-thin fragile paper 4 can bear the pressure differential of external atmosphere pressure and internal tiny structure.

As mentioned above it can be seen that have the GIS SF of the present invention of said structure feature₆Gas leakage location insulating tape, compared with having technology with oneself, has and is suitable for scene and quickly locates SF₆Gas leakage point, economic light instrument intuitively convenient, efficient.

GIS SF of the present invention₆Gas leakage location insulating tape only illustrates some preferred exemplary in this manual, is not to its restriction. This professional and technical personnel can structurally make various change or amendment according to inventive concept of the present invention and spirit.
