Abstract
The utility model relates to a device for protecting suspension insulator strings. The device is used for preventing the surfaces of the suspension insulator strings of high-voltage transmission lines, particularly ceramic or glass insulator strings, from icing into the ice cylinder and then bridging the insulator shed, so as to avoid generating the ice flashover accidents. A large-diameter protective umbrella hood which can rotate around the axis along with the wind power is arranged on the center axis of a connecting piece which consists of a ball socket and a ball head. One or a plurality of protecting devices are strung onto the upper part or the middle part of the insulator string at intervals, so as to achieve the obvious effect of preventing the insulator string from forming flashover, and obtain significant social benefit and good economical benefit.
Description
One, technical field
The utility model belongs to dish type in the ultra-high-tension power transmission line dangle porcelain or glass insulation substring protective device, and major function is to avoid insulator string because snow-broth or ice rain form icicle at the full skirt edge, causes insulator string that electric flashover takes place; Having the birds of preventing ight soil simultaneously falls at insulator string electric flashover takes place.
Two, background technology
In the high-tension transmission circuit, especially in the overhead transmission line of 220 kilovolts and above electric pressure, the insulator string of vertical hanging take place mostly electric flashover fault is because icicle bridge joint insulator full skirt or since birds ight soil fall on insulator string and cause.The power department technical staff dodges and the bird pest problem at the ice of insulator string, takes to increase insulator umbrella footpath or installs measure such as bird-resistant additional, receives certain effect, but thoroughly solves ice sudden strain of a muscle and bird pest problem, is still global problem.
Three, summary of the invention
The purpose of this utility model provides a kind of suspension insulator protective device; it can easily be connected with insulator element and articulate; and improvement is mounted on the insulator running environment of below; prevent that insulator umbrella edge from forming icicle electric flashover takes place, also can avoid birds ight soil to fall insulator surface and electric flashover takes place simultaneously.
The utility model is realized that by following technical scheme this suspension insulator has a umbrella cover with protective device, and umbrella cover central axis is equipped with metal connecting piece, so that conveniently articulate with insulator element; The connector upper end is the ball-and-socket shape, so that articulate with the bulb of insulator, the lower end of connector is the bulb shape, so that articulate with the ball-and-socket of insulator, the connector middle part is provided with at least one bearing, and the umbrella cover can rotate around the connector axle center by bearings, and the umbrella cover is provided with at least three directed fan blade, can be at wind-force effect subumbrella cover along the easily directed rotation of connector axis and since centrifugal action avoid icicle at the umbrella flaring along formation.Umbrella cover top is provided with rubber and buckles bowl, meets water freezing to prevent bearing, influences its spinfunction.
The outside dimension of umbrella cover is 350～1000mm, and concrete size determines that according to the electric pressure of transmission line umbrella cover and directed fan blade are made by insulating material or metal material.This suspension insulator protective device; apply in the high-tension transmission circuit; match the quantity of this protector according to the length of insulator string, can effectively solve the harm that ice dodges and bird pest causes of insulator string, reliably power great social benefit and economic implications are arranged guaranteeing power circuit.
Four, description of drawings
Fig. 1 is the structural representation of suspension insulator with protective device, among the figure: (1) umbrella cover, (2) ball-and-socket, (3) bearing, (4) rubber button bowl, (5) bulb, (6) directed fan blade.
Five, embodiment
Below in conjunction with drawings and Examples the utility model is described further; as shown in the figure; the suspension insulator protective device; the central axis of umbrella cover (1) is equipped with metal connecting piece; on the metal connecting piece; the lower end is ball-and-socket (2) and bulb (5) structure respectively; so that conveniently articulate with insulator; the metal connecting piece middle part is provided with bearing (3); umbrella cover (1) can pass through bearing (3) support and rotate around the metal connecting piece axis; under the wind-force effect; umbrella cover (1) is promoted by fan blade (6); around the directed rotation of connector; the sleet or the snow-broth at umbrella cover (1) edge are got rid of outward by the rotary centrifugal force effect, avoid forming sagging icicle, thereby can effectively prevent the generation of insulator ice sudden strain of a muscle accident.The top of umbrella cover (1) is established rubber and is buckled bowl (4), and avoiding rotary part such as bearing to meet water freezing influences umbrella cover (1) and bearing (3) rotating effect.Umbrella cover (1) is made by insulating material or metal material, and the outside dimension of umbrella cover (1) can be determined different sizes according to the transmission line electric pressure, and the high more size of ordinary circumstance electric pressure is big more, determines between diameter 350～1000mm.
Protection range of the present utility model not only is confined to present embodiment, and its protection range is determined by claims.
Claims (5)
1. the utility model is the suspension insulator protective device, it is characterized in that the central axis of umbrella cover (1) is equipped with metal connecting piece, and the metal connecting piece upper end is ball-and-socket (a 2) shape, and the lower end is bulb (a 5) shape.
