Background

In transmission of power transmission lines, lightning phenomena often occur in thunderstorm days, and the damage of lightning to power transmission is large, so that insulators need to be additionally arranged in the power transmission lines. In the prior art, in order to conveniently observe whether the insulator is damaged or not, a pressure release hole is formed in the insulator, so that when the internal flashover fault of the lightning protection insulator occurs due to multiple lightning strikes and direct lightning strikes, internal gas is heated, the pressure is increased, and the internal pressure is quickly released, so that the situations of opening a hardware fitting and exploding an epoxy cylinder are prevented, and an insulated wire is protected from being damaged; in order to conveniently observe the failed lightning protection insulator, a fault indicating ring is additionally arranged at the position of the pressure release hole, the fault indicating ring comprises an inner side reflective strip and an outer side fault indicating mark, and after the insulator is damaged by lightning, the inner side reflective strip can be exposed, so that operation and maintenance personnel can conveniently find the failed lightning protection insulator to replace the failed lightning protection insulator when checking a circuit.

However, the fault indication ring in the prior art has the following defects: due to the influence of the umbrella skirt structure, the fault indicating ring is not easy to see below the tower pole, a certain angle is needed, special terrains, such as certain tower poles in mountainous areas are on the mountain heads, the fault indicating ring and the light reflecting strip cannot be seen at a far distance, the sight line under the tower pole is influenced by the large umbrella skirt, and the fault indicating ring cannot be seen;

similarly if the thunderbolt trouble appears, the back is broken away to the fault indication ring, and yellow reflection of light strip just can be found to the same angle that needs, and reflection of light strip material is not high temperature resistant, and lightning protection insulator is struck by lightning, and inside high temperature can lead to reflection of light strip to be burnt out, patrols the unable fault point of seeking of line in-process night.

Disclosure of Invention

The technical problem to be solved by the invention is to overcome the defects of the prior art and provide a method.

In order to solve the technical problem, the invention provides a fault indication type lightning protection insulator which comprises an insulator body, wherein two symmetrical pressure release holes are formed between two adjacent umbrella skirts in the insulator body, and two semicircular fault indication rings are sleeved at the pressure release holes through buckles; the outer side of the fault indicating ring is connected with an arc-shaped block through a supporting piece, and the arc-shaped block is at least aligned with the edge of the umbrella skirt; the outer surface of the arc-shaped block is provided with a layer of reflective strips.

Furthermore, in order to facilitate the operation and maintenance personnel under the tower pole to observe the light reflecting strips, the arc-shaped block is inclined downwards at an angle of 30-45 degrees.

Furthermore, in order to achieve the purposes of dust prevention, water prevention and color fading prevention of the reflective strip after long-time sunlight irradiation, the outer surface of the reflective strip is provided with a transparent protective layer made of plastic or silica gel.

Furthermore, for the sake of beauty, visual effect enhancement and identification degree improvement, the arc-shaped block and the semicircular fault indicating ring are the same circle center, and the arc length of the arc-shaped block is greater than that of the semicircular fault indicating ring.

Furthermore, for convenience of installation and when the limit of the lightning protection insulator is reached, the fault indicating ring is quickly bounced off, a clamping piece is arranged at one end of the semicircular fault indicating ring, and a clamping groove matched with the clamping piece is formed in the other end of the semicircular fault indicating ring.

Furthermore, in order to prevent the product from colliding in the transportation or installation process and causing the breakage of the fault indication ring, the number of the supporting pieces is two, one end of each supporting block is connected with the arc-shaped block, the other end of each supporting block is connected with the fault indication ring, the extension line of the other end of each supporting block passes through the circle center, and the structure forms a triangular structure with the extension line intersected at the circle center, so that the structure is more stable.

The invention achieves the following beneficial effects:

the lightning protection insulator is provided with the arc-shaped blocks and the reflective strips, and the arc-shaped blocks are at least aligned with the edges of the umbrella skirt, so that the umbrella skirt cannot shield the sight, and maintenance personnel can conveniently observe the reflective strips; because the reflection of light strip has set up on the arc piece, when thunderbolt, the fault indication ring is washed away by internal pressure, and after the fault indication ring drops, whether there is the judgement fault point through the reflection of light strip, if do not have the reflection of light effect to exist promptly indicates that this product suffers the thunderbolt, and the product is punctured, need carry out the change of product, otherwise indicates that the product normally operates.
