The pollution-resistant device can reduce the pollution-resistant situation of the surface of the multi-environment insulator lightning arrester, thereby greatly improving the pollution-resistant capacity of the whole multi-environment insulator lightning arrester.

The ice-preventing umbrella 104 can prevent ice flash caused by ice bridge, and thus, the ice flash voltage is increased to reduce the occurrence of ice flash.

While the diameters of the first and second anti-icing umbrellas 104 and 104 are appropriately increased, the diameters of the first and second anti-icing umbrellas 104 and 104 should be larger than the diameter of the large anti-fouling umbrella 103. Optionally, the diameter of the first anti-icing umbrella 104 and the second anti-icing umbrella 104 is at least twice the diameter of the large anti-fouling umbrella 103 plus the thickness of the ice.

In other embodiments, the large and small anti-fouling umbrellas 103 and 103 are staggered with the first and second anti-icing umbrellas 104 and 104.

In some embodiments, the arc ignition rod 106 is inserted into the first electrode, and an insulating layer is wound on the surface of the arc ignition rod 106 from the first electrode to the direction away from the first electrode.

The surface of the arc striking rod 106 is further provided with an insulating layer for transmitting current to the first electrode when the arc striking rod 106 is conducted, so as to prevent the current from breaking through the arc striking rod 106 in the conducting process. The insulating layer on the surface of the arc ignition rod 106 is wound from one end close to the first electrode 102 to the end far away from the first electrode. The insulating layer wound on the surface of the arc striking rod 106 can avoid personal accidents caused by high-voltage suspension potential.

In another embodiment, the insulating layer on the surface of the arc ignition rod 106 is wound from the end far away from the first electrode to the end near the first electrode.

In another embodiment, the surface of the arc ignition bar 106 is provided with an integrally formed insulating layer.

In some embodiments, the arc ignition rod 106 is bent toward an end away from the second electrode, and an included angle between the bent section and the non-bent portion of the arc ignition rod 106 is an obtuse angle.

Specifically, the arc starting rod 106 is bent towards the end far away from the second electrode, the included angle between the bent section of the arc starting rod 106 and the non-bent section of the arc starting rod 106 is an obtuse angle, and the non-bent section of the arc starting rod 106 and the multi-environment insulator lightning arrester are arranged in a right angle. The arc ignition rod 106 may also be bent towards the end near the second electrode.

In other embodiments, the arc ignition bar 106 is bent toward an end near the second electrode, and the bent portion of the arc ignition bar 106 and the non-bent portion of the arc ignition bar 106 form an obtuse angle. The unbent section of the arc ignition rod 106 and the multi-environment insulator lightning arrester are arranged at a right angle.

In particular, the ignition ball 107 is provided with a cylindrical recess for mating with the ignition rod 106. The arc striking ball 107 and the first hardware 101 form a gap, and the reliable action of the gap has a protection effect on a current source loop, can reduce inductance and has a shielding effect of certain current.

The size of arc striking ball 107 is not limited herein, and the diameter of arc striking ball 107 can be adjusted appropriately according to the voltage of the power transmission network to ensure that the gap discharge voltage value and stability requirements are met. Optionally, the diameter of the arc striking ball 107 is phi 10-phi 20mm, and the arc striking ball 107108 with the size is not easy to cause gap short circuit when being subjected to rain, icing, accumulated snow and accumulated bird dung.

In some embodiments, the anti-fouling umbrella 103 and the anti-icing umbrella 104 are silicone rubber composite.

Specifically, the silicone rubber composite material has good insulativity, has high chemical stability, further has heat resistance and low glass transition temperature, has heat resistance and good cold resistance, and therefore the silicone rubber composite jacket has a wide application range. Meanwhile, the silicone rubber jacket has good waterproofness and insulativity, the problem of electric leakage cannot be caused, and insulating silicon can be generated even after combustion.

In other use scenes, the silicon rubber composite material has better aging resistance, and the silicon material has good ultraviolet resistance, is not easy to age due to ultraviolet irradiation and also generates cracks due to aging after long-term use.

In some embodiments, the skirt angle of the anti-fouling umbrella 103 is not less than 15 degrees.

Specifically, the angle of the anti-fouling umbrella 103 is increased, so that the adhesion of dirt can be reduced, and the influence of more attached dirt on the use of the multi-environment insulator lightning arrester is avoided.

In other embodiments, the distance between the first and second fittings 101, 102 is increased.

Specifically, the occurrence of rain flashover of the multi-environment insulator lightning arrester is mainly caused by the fact that the distance between the electric arcs of hardware fittings at two ends is too short. The dry lightning voltage is a flashover voltage of the insulator 200 with a clean and dry surface under the action of voltage, and the rain lightning voltage is a flashover voltage of the insulator 200 with a clean surface under the action of voltage under the condition of overhigh humidity or rain. The voltage at which rain flashes occur is about 95% of the dry flash voltage. When the hydrophobic coating expressed by the multi-environment insulator lightning arrester is weakened or lost, the rain lightning voltage can be obviously reduced. The flashing distance is the maximum value according to the diameter of the set anti-fouling umbrella 103 or the rain-proof umbrella skirt, so that the safe operation of the composite insulator 200 cannot be seriously threatened under the condition of rain. Optionally, the flash pitch is set to be greater than 25-30 mm.

In other embodiments, the silica gel composite material further comprises the following raw materials, by weight, 100 parts of methyl vinyl silicone rubber, 20-30 parts of borosilicate rubber, 20-30 parts of perfluoro ether rubber, 15-20 parts of phenolic resin, 2-4 parts of dibenzoyl peroxide, 0.5-1.5 parts of triallyl citrate, 5-10 parts of a silane coupling agent, 2-3 parts of hydroxy silicone oil, 2-3 parts of diphenylsilanediol, 2-3 parts of dithiocarbamate, 15-20 parts of channel black, 20-30 parts of fumed silica, 10-20 parts of argil, 0.5-1 part of light stabilizer GW-540, 0.2-0.4 part of 2-hydroxy-4-n-octyloxy benzophenone, and 2-3 parts of liquid paraffin.

In particular, dibenzoyl peroxide and triallyl citrate are vulcanization systems: the silicone rubber which is made of the silicone rubber composite material of the anti-fouling umbrella 103 and the anti-icing umbrella 104 has excellent dry-hot air aging resistance, but does not resist wet-hot aging, and when excessive moisture is contained in the air, vulcanized rubber can be strongly degraded. For example, the strength of the vulcanizate is essentially unchanged after aging of the silicone rubber at 300 ℃ for 24h, whereas the strength and other mechanical properties are severely affected when the humidity is 180g/m 2. In addition, the silicon rubber can be strongly degraded under the airtight aging condition that air is not circulated, so that the performance is deteriorated, and the moist heat aging performance of the silicon rubber can be well improved through a preferable vulcanization system. The sulfur can improve the mechanical property of peroxide vulcanized rubber, but the heat resistance is reduced, and the influence on a vulcanization system can be reduced by adding furnace carbon black and fumed silica. The hindered light stabilizer and the ultraviolet absorber are used in a matched mode, so that the aging caused by illumination is reduced, and the service life of the material is prolonged. In conclusion, the formula highlights the moisture and heat aging resistance of the material, prolongs the service life of the material and reduces the power operation failure rate in high-humidity and high-heat areas on the basis of meeting other physical and mechanical properties.

In another embodiment, the insulator 200 employs an epoxy core, typically formed by high temperature pultrusion of glass fibers impregnated with a high temperature resistant epoxy matrix. The high-voltage cable has the characteristics of high voltage, corrosion resistance, no deformation or delamination, long service life, stable mechanical property, excellent insulating property and the like, and has relatively excellent tensile resistance. Due to the excellent anti-stretching capacity, cracks can be prevented from appearing on the surface of the core body, and the moisture absorption of the core body can be inhibited, so that the lightning protection performance is improved.

In another embodiment, when the first metal fitting 101, the second metal fitting 102, the arc striking rod 106 and the multi-environment insulator lightning arrester are connected, a dustproof and waterproof rubber ring is added to prevent moist air and water drops from entering the multi-environment insulator lightning arrester, so that the ageing resistance of the multi-environment insulator lightning arrester is improved.

In summary, the multi-environment insulator arrester disclosed by the application utilizes the anti-fouling umbrella 103 and the anti-icing umbrella 104 which are arranged outside the insulator 200 and the arrester 300 at intervals, so that the potential safety hazard of power transmission of a power system in a severe environment is reduced.
