Abstract
A waterproof cover of a universal outdoor knife switch operating mechanism box is provided. The waterproof cover comprises a disc shaped cover body which can be tightly clung to the operating mechanism box, the upper part is provided with a cup joint cylinder which can be sleeved on an operation connecting rod, at least a hose clamp for fastening the cup joint cylinder on the operation connecting rod is arranged on the cup joint cylinder; the disc shaped cover body is horn shaped, the cup joint cylinder is integrally arranged, and two hose clamps are arranged on the cup joint cylinder. The waterproof cover is simple in structure and convenient and reliable in use, the waterproof cover is suitable for knife switch operation mechanisms of different models, the situation that a rubber sealing ring is aged, and water seepage of the knife switch operating mechanism box occurs can be avoided, service life of the knife switch can be prolonged, production costs and maintenance costs can be reduced, safe and stable operation capability of power transformation equipment can be enhanced, occurrence probability of defects can be reduced, and labor efficiency can be enhanced.
Description
Technical field
The utility model relates to a kind of bucker of universal outdoor switch blade operating mechanism case, belongs to the water-tight device of electric power system special use.
Background technology
In prior art, for waterproof, universal outdoor switch blade operating mechanism case be plug-in strip easily leak or the rotating mechanism position installs the sealing ring of rubber additional, utilize the sealing of rubber to strengthen the anti-rainwater ability of switch blade mechanism; Perhaps make respectively special-purpose bucker for the plug-in strip operating mechanism of different model.Their major defect is: the easy aging of rubber that the former adopts, namely lose effect after after a while, and the latter adopts special-purpose bucker, and lack universality, cost is expensive, thereby can't popularization and application.
In recent years, the situations such as electric substation's direct current is abnormal, the frequent displacement of backstage plug-in strip remote signalling happen occasionally, according to on-the-spot actual treatment situation, most direct currents is abnormal, the frequent displacement of plug-in strip remote signalling is plug-in strip auxiliary contact defective insulation and causes, and the reason that causes plug-in strip auxiliary contact defective insulation mostly is the infiltration of switch blade mechanism case, this problem perplexs the maintainer always, and plug-in strip manufacturer also fails to propose effective solution.
Field exploring, outdoor plug-in strip operating mechanism are seldom carried out the inspection and maintenance of specialty for its sealing after building up operation.The rubber that its waterproof measure mainly is installed in when dispatching from the factory between operating mechanism and mechanism case is realized.Time one length is accompanied by ageing of rubber and the mechanism surface surface oxidation, breakage occur, even splits, and just makes water stain access arrangement inner, causes insulation breakdown, and the equipment that affects normally moves.
In addition, present existing minority tailored version switch blade mechanism case bucker is constant dimension often, can only be applied to a kind of plug-in strip of model and can't popularize.
We expect realizing by the universal type waterproof cover that installs a bore type variable in plug-in strip actuating connecting rod place additional the water-proof function of switch blade mechanism, utilize simultaneously its universality, break original tailored version bucker can only for a kind of model can not popularization, really realize the bucker that various plug-in strip types all can be used.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of simple in structure, easy to use and reliable, can be applicable to the plug-in strip operating mechanism of different model, and the situation that plug-in strip operating mechanism case can not seep water because rubber seal is aging is occured, can extend switch blade mechanism useful life, reduce production costs and maintenance cost, improve converting equipment safe and stable operation ability, the reduce injection defect probability of happening, the bucker of the universal outdoor switch blade operating mechanism case of raising labour efficiency.
The purpose of this utility model is completed by following technical solution, it comprises that one can be close to the disc cover body of operating mechanism case, its top is provided with a socket tube that can be socketed on operator link, and disposes on described socket tube and at least one socket tube is fastened on larynx hoop on operator link.
Described disc cover body flare shape, it is connected with the socket tube that arranges on it, disposes twice larynx hoop on socket tube.
The utlity model has simple in structure, easy to use and reliable, can be applicable to the plug-in strip operating mechanism of different model, and the situation that plug-in strip operating mechanism case can not seep water because rubber seal is aging is occured, can extend switch blade mechanism useful life, reduce production costs and maintenance cost, improve converting equipment safe and stable operation ability, the reduce injection defect probability of happening, the characteristics such as raise labour efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Figure 1, the bucker of universal outdoor switch blade operating mechanism case described in the utility model, it comprises that one can be close to the disc cover body 2 of operating mechanism case 1, its top is provided with a socket tube 4 that can be socketed on operator link 3, and disposes on described socket tube 4 and at least one socket tube 4 is fastened on larynx hoop 5 on operator link 3.
Described disc cover body 2 flare shapes, it is connected with the socket tube 4 that arranges on it, disposes twice larynx hoop 5 on socket tube 4.
The material of rain cover main part described in the utility model is stainless steel, and the main part internal layer adopts the absorption of enhanced rubber sealing ring; Larynx hoop and main part are supporting, play the role of fastening, and adjustable size.
The diameter that the scope of application of universal outdoor switch blade operating mechanism case bucker has been included all actuating connecting rods is the model of 1 inch-2 inches; almost be applicable to plug-in strip types all in present electric substation; having replaced specificity plug-in strip bucker can only be suitable for a kind of plug-in strip model shortcoming; both reduced cost; make again its protection range obtain great expansion, for its popularization provides prerequisite and guarantee.
Installing additional of universal outdoor switch blade operating mechanism case bucker is simple; do not need equipment to have a power failure; it has solved the plug-in strip operating mechanism of existence all the time after building up operation to the protection of protecting outer switch blade mechanism case; seldom carry out the problem of professional inspection and maintenance for its sealing; the life-span of plug-in strip is extended greatly; electric substation's direct current is abnormal, the frequent displacement fault of backstage plug-in strip remote signalling probability of occurrence reduces greatly; improved the ability of power network safety operation; reduce the security risk of work, improved labor productivity.
Claims (2)
1. the bucker of a universal outdoor switch blade operating mechanism case, it comprises that one can be close to the disc cover body of operating mechanism case, the top that it is characterized in that described disc cover body is provided with a socket tube that can be socketed on operator link, and disposes on described socket tube and at least one socket tube is fastened on larynx hoop on operator link.
2. the bucker of universal outdoor switch blade operating mechanism case according to claim 1, is characterized in that described disc cover body flare shape, and it is connected with the socket tube that arranges on it, disposes twice larynx hoop on socket tube.
