Description
Technical field
The utility model relates to a kind of line protection, belongs to the insulator technical field.
Background technology
The safety of ultra-high-tension power transmission line is power department problem very deeply concerned always, and natural calamities such as ice sudden strain of a muscle, rain sudden strain of a muscle, bird pest are the important contents in the potential safety hazard that exists at present.It is the cold district common phenomena that ice dodges, and in the winter time, the circuit suspension insulator is easy to accumulated snow and freezes, and especially distance is little between the synthetic insulator umbrella, easier generation.The icing back of insulator string forms the icicle of whole string, and when the thawing of temperature rising icicle, the frozen water of thawing forms continuous frozen water and slips along dropping down under the suspension insulator edge, and this just may cause insulator short circuit tripping operation, and power outage takes place; It is that rainwater forms continuous discharge eaves gutter along the suspension insulator edge because distance is little between synthetic insulator that the rain sudden strain of a muscle takes place, and causes insulator short circuit tripping operation probably; Bird pest is because the object that bird ight soil of discharging on the hanging point cross-arm on insulator string or mouth are held in the month drops on the insulator string edge when falling, electric field distortion causes point discharge around making the insulator string between the following hanging point of the last hanging point of earth electrode and electrified body, causes flashover fault.Solving above-mentioned potential safety hazard has great significance to the safe operation that guarantees transmission line.
Summary of the invention
Thereby technical problem to be solved in the utility model provides the high-tension insulator flash suppressor that a kind of generation that can avoid icing accidents such as sudden strain of a muscle, rain sudden strain of a muscle, bird pest guarantees the safe operation of transmission line.
The technical scheme that addresses the above problem is:
A kind of high-tension insulator flash suppressor, it is the umbrella protective cover of being made by insulating material, the central authorities of protective cover are fixed sleevings, the external diameter of its internal diameter and insulator holder is complementary, and the protective cover umbrella cover is downward-sloping, and the angle of umbrella cover radius and horizontal plane is the 8-20 degree, protective cover splits along radius from the center and is divided into main part and free section, main part accounts for 1/2～3/4 umbrella cover, and free section accounts for 1/2～1/4 umbrella cover, and the edge that two parts join is for removably connecting.
Above-mentioned high-tension insulator flash suppressor is coated with hydrophobic coat on umbrella cover, the surface of hydrophobic coat also scribbles red chromatograph.
Above-mentioned high-tension insulator flash suppressor is provided with 3～4 reinforcements on the described umbrella cover, reinforcement is rectangular semi-cylindrical hill, begins along radius distribution from fixed sleeving.
Above-mentioned high-tension insulator flash suppressor, the edge that described two parts join is provided with overlapping coupling part, offers screw on overlapping coupling part, and connecting bolt is fixed together main part and free section.
Above-mentioned high-tension insulator flash suppressor, described umbrella cover diameter is 580～700mm.
The utility model can be installed in the top of line insulator, and the umbrella cover of protective cover can be protected on the full skirt of insulator and can not freeze, and runs through the type icicle thereby can not form bunch of insulator, has avoided icicle to melt and has caused insulator short circuit tripping operation.Equally, because the protection of umbrella cover makes rainwater can not form continuous discharge eaves gutter at the insulator string edge, avoided the rain sudden strain of a muscle; Umbrella cover stops that also birds droppings and other dirt drop on around the insulator, can not influence insulator field intensity on every side, avoids the insulator short circuit.Protective cover is divided into two parts and is convenient to installation and removal, and it is very convenient to construct.

Embodiment
As seen from Figure 1, the utility model is a kind of umbrella protective cover, and the central authorities of protective cover 4 are fixed sleevings 5, and the diameter of its internal diameter and insulator holder 2 is complementary, and is installed in the top of line insulator 1.The umbrella cover 5 of protective cover 4 can protect on the insulator 1 cluster parachute not freeze, and runs through the type icicle thereby can not form bunch of insulator, has avoided icicle to melt and has caused insulator short circuit tripping operation; Equally, because the protection of umbrella cover 5 makes rainwater can not form continuous discharge eaves gutter at insulator 1 edge, avoided the rain sudden strain of a muscle; Umbrella cover 5 stops that also birds droppings and other foreign material drop on around the insulator, can not influence insulator field intensity on every side, keeps away angle insulator short circuit.
Protective cover umbrella cover 5 diameters are 580～700mm, protective cover 4 is divided into main part and free section 8 from the center along radius, main part accounts for 1/2～3/4 umbrella cover, free section 8 accounts for 1/2～1/4 umbrella cover, the edge that two parts join is for removably connecting, elder generation is enclosed within the fixed sleeving 6 of main part on the insulator holder 2 during installation, with the breach polishing of free section 8 with umbrella cover 5, is connected and fixed with main part again.Fig. 2 shows that also 3～4 reinforcements 7 are arranged on its umbrella cover 5, and reinforcement 7 is rectangular semi-cylindrical hill, from umbrella cover 5 centers along radius distribution.In the present embodiment, for strengthening the intensity of two parts junction, the place is provided with reinforcement 7 in two-part adjoining edge, during connection, the reinforcement 7 at two parts edge is overlapped, and is fixing with fastening bolt 10 again, and Fig. 3 shows is cross section enlarged diagram after fixing.
As seen from Figure 1, protective cover umbrella cover 5 has a down dip along circumferential, and the angle a of umbrella cover radius and horizontal plane is the 8-20 degree, and present embodiment adopts 18 degree.
