Problems solved by technology

The disadvantage of this structure is that during the operation, the operator must manually paste the narrow insulation blanket and the wide insulation blanket. During this process, the operator is in contact with the electrified body, which has certain potential safety hazards; The surface is easy to attach dirt and wear, which will reduce the creepage distance of the pin type. When carrying the relative ground voltage, leakage current will occur, and flashover along the surface will occur. In serious cases, it will cause relative ground short circuit.
The disadvantage of this structure is: the structure does not have waterproof and moisture-proof functions, and the outdoor effect is not good

Embodiment 1

[0029] Such as figure 1 and figure 2 As shown, the present invention discloses an insulating and insulating cloth. The insulating and insulating cloth is rectangular as a whole, including a waterproof layer 1, a support layer and an inner lining layer 2 arranged from the outside to the inside. The waterproof layer 1 includes a spun-bonded non-woven fabric and a coated The waterproof coating on the outer surface of the spunbond non-woven fabric, the waterproof coating is a PTFE film, and the support layer includes an upper adhesive layer 3, a lower adhesive layer 4 and a layer between the upper adhesive layer 3 and the lower adhesive layer 4 Insulation layer 5, insulation layer 5 includes polyurethane, antioxidant and cross-linking agent, antioxidant is a kind of in antioxidant 1010, antioxidant DLTP and antioxidant 168, preferred antioxidant DLTP in this implementation, adhesive The composite layer 3 and the lower adhesive layer 4 are made of water glass, the inner lining la...

Embodiment 2

[0033]Such as Figure 3 to Figure 5 As shown, the present invention includes a waterproof layer 1, a support layer and an inner lining layer 2 arranged from outside to inside, and the waterproof layer 1 includes a spunbonded nonwoven fabric and a waterproof coating coating the outer surface of the spunbonded nonwoven fabric, and the waterproof coating The layer is a PTFE film, and the supporting layer includes an upper adhesive layer 3, a lower adhesive layer 4, and an insulating layer 5 arranged between the upper adhesive layer 3 and the lower adhesive layer 4, and the insulating layer 5 includes polyurethane, antioxidant and cross-linking layer. Joint agent, antioxidant is one of antioxidant 1010, antioxidant DLTP and antioxidant 168, preferred antioxidant DLTP in this implementation, upper adhesive layer 3 and lower adhesive layer 4 adopt water glass, inner The lining layer 2 is polyamide fiber interwoven with warp and weft, the inner side of the waterproof layer 1 is bonde...

Embodiment 3

[0036] The structure of this embodiment is basically the same as that of Embodiment 2, the difference is: as Figure 6 As shown, the ends of the first hook 10 and the L-shaped hook 13 are M-shaped, especially the ends of the first hook 10 and the L-shaped hook 13 are designed to be M-shaped, and the angle between the two free ends 14 of the M-shaped structure is 90°. °, the structure of the first hook 10 is shown in the figure. When this structure is in use, the two free ends of the M shape are attached to the two side walls of the lower end of the cuboid cabinet, and the corners of the cuboid are stuck in the concave of the M shape structure. At the groove 15, this design can effectively increase the contact area between the first hook 10 and the second hook and the electrical equipment, thereby improving the stable strength between the present invention and the electrical equipment.

Abstract

The invention discloses insulated isolation cloth, and the cloth comprises a waterproof layer, a supporting layer and a lining layer from the outside to the inside. The supporting layer comprises an upper bonding layer, a lower bonding layer, and an insulating layer between the upper bonding layer and the lower bonding layer. The inner side of the waterproof layer is bonded with the upper bonding layer, and the inner side of the lining layer is bonded with the lower bonding layer. The edge of the cloth is provided with a plurality of insulating hanging rings (6), and the insulating hanging rings (6) are respectively provided with a hanging rope (7), wherein the other end of each hanging rope (7) is provided with an insulating hook (8). The cloth provided by the invention can cover adjacent electrified bodies at an interval, and the edge of the cloth is firmly fixed with an electric appliance through the hanging ropes (7) and the insulating hooks (8). Even if a maintainer tumbles accidentally, electric shock cannot happens to the maintainer, so the cloth can avoid the accidental electric shock.

Description

technical field [0001] The invention belongs to the technical field of power transmission and transformation operation and maintenance, and in particular relates to an insulating isolation cloth. Background technique [0002] The distance between the internal and external open equipment of 35 kV and below in the substation room is small. When the equipment is powered off for maintenance, the live equipment in the adjacent interval poses a great threat to the personal safety of the maintenance personnel, especially the live cable heads in the switch cabinet. Sometimes it is necessary to install a layer of insulating shielding equipment between the human body and the charged body to make up for the lack of air gap. This method is usually called insulation isolation measures. When using clips, the homework must be packed tightly. Before using the insulating blanket, first observe whether the binding wire on the double-needle porcelain bottle is flat, so as to prevent the insul...
