Description
Technical field
The utility model relates to a kind of protector, particularly a kind of high pressure disconnecting link protector.
Background technology
The high pressure disconnecting link belongs to the power consumer external equipment, is fixed on tower bar cross-arm below.Often build Bird's Nest on the cross-arm, built the foreign material of Bird's Nest if drop on the high pressure disconnecting link, can cause fault, for circuit brings very big potential safety hazard.The high pressure disconnecting link is directly exposed to the open air, is subjected to causing the disconnecting link corrosion easily after the invasion and attack of sleet, causes disconnecting link normally not draw back, and has a strong impact on operating efficiency and electric power feeding time.Because high pressure disconnecting link work under bad environment out of doors, equipment surface can be adhered to dunghill, is prone to pollution flashover accident.Bird pest, corrosion, pollution flashover are the major reasons that causes high pressure disconnecting link fault.
Employing is at present taken precautions against the fault generation in the mode that the high pressure disconnecting link installs protector additional, and existing protector mainly contains 2 kinds, and all-sealed protector and full open type protector find that at work there is following shortcoming in existing sealed type insulating shield:
1, complex structure, the blade of high pressure disconnecting link and both sides binding post install insulating shield respectively additional, install inconvenient.
2, because binding post is insulated guard shield and covers fully, can't see fault indices such as spark tracking, influence trouble shoot.
3, the blade of high pressure disconnecting link is insulated the guard shield parcel, makes the drawing disconnecting link restricted.
4, the high pressure disconnecting link is outdoor equipment, because insulating shield wraps equipment fully, moisture is difficult for dispersing after the sleet, and corrosion easily takes place equipment.
5, insulating shield is at outdoor easy dust stratification, after the high pressure disconnecting link draws back, owing to the generation creepage phenomenon that is covered with dust all on the insulating shield, the serious threat person and device security.
6, easily cause during the drawing disconnecting link insulating shield to damage.
7, for the drawing disconnecting link, the sealed type insulating shield must leave opening in the contact position of the dynamic/static contact of disconnecting link, runs into sleety weather, has the into situation generation of water, thereby causes operating a switch corrosion between ring and the locking ditch, causes disconnecting link to draw back.
The easy dust stratification of existing full open type protector, after disconnecting link drew back, the generation creepage phenomenon that is covered with dust all on the protector had lost the effect of obvious cut-off point, the serious threat person and device security.
The utility model content
Technical problem to be solved in the utility model provide a kind of simple in structure, easy for installation, be beneficial to trouble shoot, not fragile, can improve equipment dependability and fail safe, reduce that material drops into and the high pressure disconnecting link protector of workman's amount of labour.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of high pressure disconnecting link protector, the insulating shield main body that comprises semi-closed structure, the upper surface of this insulating shield main body is provided with the fixing hole that matches with the set bolt of high pressure disconnecting link, also is provided with on the described insulating shield main body for the observation window of observing the high pressure disconnecting link.The insulating shield main body adopts semi-enclosed design, the harm that can effectively prevent bird pest, corrosion, pollution flashover etc. that circuit is caused; The bottom is unenclosed construction, can carry out operations such as drawing disconnecting link easily, is beneficial to distributing of moisture behind the sleet, makes the high pressure disconnecting link be difficult for taking place corrosion.Observation window can be seen fault indices such as spark tracking easily, is beneficial to trouble shoot.
Preferably; the prismatoid that the bottom of described insulating shield main body surrounds for the rigid insulation material; the cuboid that the top of described prismatoid surrounds for the rigid insulation material; the left and right side of this cuboid is provided with described observation window, baffle before and after the front and back sides of described prismatoid extends respectively vertically downward.The design that the insulating shield main body has adopted the inclined plane to combine with vertical plane can be carried out effective water conservancy diversion to rainwater, reduces the deposition of dust simultaneously.
Preferably, the upper surface of described insulating shield main body is provided with the insulation protection pad, and this insulation protection pad is provided with the through hole corresponding with described fixing hole.The insulation protection pad can make insulating shield closely contact with cross-arm, guarantees fixed effect.
Preferably, described observation window is shutter.Adopt the design of shutter can effectively keep out sunlight to the irradiation of high pressure disconnecting link, delayed the aging of high pressure disconnecting link, prolonged the useful life of high pressure disconnecting link.
The utlity model has anti-bird pest, anti-corrosion, anti-pollution flashover, simple in structure, easy for installation, be beneficial to trouble shoot, fragile, not safe and reliable advantage, reliability and the fail safe that can also further improve the high pressure disconnecting link.This utility model is because simple in structure, easy for installation, thereby can reduce the input of material and workman's the amount of labour.The generation of bird pest fault on the disconnecting link can be stopped after the use, the generation of corrosion fault can also be reduced.If cooperate the strain insulator bar, and adopt the jointless company of insulated conductor to draw mode, can in the distribution scope, stop the generation of bird pest fault, realize the harmonious coexistence of Bird's Nest and controller switching equipment.
