Abstract
The utility model discloses a protective cover of a rigid suspension insulator. The protective cover comprises a body and a bolt nut assembly protection portion, the body is a disc-shaped object formed by fixed connection of two semicircular bodies via a fastener, the body comprises a protective cover upper surface, protective cover skirt edges, and connecting portions connected with channel steel, the protective cover upper surface is also provided with a plurality of drain channels at intervals separated by flanges, and the connecting portions are fit with the dimension of the channel steel. According to the protective cover of the rigid suspension insulator, the installation is convenient, windproof performance, waterproof performance, and corrosion resistance are achieved, and influences of various negative factors such as humidity, wind speed, shock and dust etc. in a tunnel on the insulator can be overcome.
Description
Technical field
The utility model relates to a kind of frock for Metro Network, specifically, relates to a kind of rigid suspended insulator protective cover of the contact line for Metro Network.
Background technology
In track traffic, the rigid suspended insulator of contact line is in operation and is subject to tunnel leak and corrosivity sewage directly drops to location insulator surface, and tunnel sewage is generally acid, it is the medium very easily conducting electricity, thereby produce secondary problem to a certain degree, when the dirty of insulator surface acquires a certain degree, when creepage distance is inadequate, cause insulator arc-over to puncture impact operation.Drip to insulator and cause creeping discharge as, anchor point place, insulator breakdown explosion the most at last, causes insulator breakage failure; The insulator arc-over causing due to tunnel leak punctures, and causes insulator release failure; Tunnel top leaks to the rigidity porcelain vase at anchor point place, and this rigidity porcelain vase surface, place contaminated (material dripping when work business leak stopping), finally causes porcelain vase surface breakdown, causes porcelain vase electric discharge etc.
Once insulator causes losing location suspension effect as hanging the cracked meeting of stressed member generation insulation breakdown, finally makes this hitch point place bus-bar sagging, occurs serious arcing phenomenon while causing pantograph to be streaked, contact wire and bus-bar can scaling loss.Insulator generation edge flashing phenomenon can cause the equipment transient earthing of touching net, and makes the DC high-speed switch action of traction substation, and touching net also can instantaneous dead electricity, causes the decline of quantity of operation and has reduced relevant power supply unit useful life.Insulator permanent earth originates from repeatedly flashover phenomenon and finally causes due to the carbonization of insulator built-in electrical insulation medium.Insulator permanent earth can make this supply arm dead electricity, final impact operation.
Consider the degree size of leaking in tunnel, require protective cover to there is good drainage performance and hydrophobicity performance.In tunnel, because the impact of electric passenger vehicle driving exists Piston Action Wind, require protective roof structure wind resistance good.The quantity of installing due to needs is many, so it is convenient to require protective cover to install.Consider the corrosivity of leaking in tunnel, require the material corrosion resistance of insulator protective cover good.May infiltrate insulator bolt place owing to leaking in tunnel, require protective cover can protect bolt and the nut at this place.
Summary of the invention
The purpose of this utility model is to provide a kind of protective cover for the protection of insulator, and this protective cover can overcome because of the impact of every unfavorable factor on insulator such as humidity, wind speed, vibrations, dusts in tunnel, and water resistance is good.
For achieving the above object, the utility model provides a kind of rigid suspended insulator protective cover, and this protective cover comprises: body, and bolt and nut component protection department, and this body is fixedly connected to form discoid by two semicircular body by fastener, and it comprises:
Protective cover upper surface;
Protective cover shirt rim;
Protective cover upper surface also interval arranges some rhones of separating by flange; And
The connecting portion being connected with channel-section steel, the size of this connecting portion coupling channel-section steel.
Above-mentioned rigid suspended insulator protective cover, wherein, described body is fixedly connected with by two symmetrically arranged fasteners.
Above-mentioned rigid suspended insulator protective cover, wherein, is also provided with Fixed latches on described fastener, loosening to prevent two semicircular body above-below direction.
Above-mentioned rigid suspended insulator protective cover, wherein, protective cover upper surface has the gradient, make drainage better, and protective cover of the present utility model is also provided with rhone, can prevents that tunnel water from flowing to bus-bar along protective cover, thereby may cause the secondary problems such as bus-bar corrosion.
Above-mentioned rigid suspended insulator protective cover, wherein, described shield body also comprises the reinforcement that is arranged on connecting portion place.
The convenient installation of rigid suspended insulator protective cover that the utility model provides, has windproofly, and water resistance, can be anticorrosive, can overcome because of the impact of every unfavorable factor on insulator such as humidity, wind speed, vibrations, dusts in tunnel.
Accompanying drawing explanation
Fig. 1 is the vertical view of rigid suspended insulator protective cover of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is that rigid suspended insulator protective cover of the present utility model is installed to the installation design sketch on insulator.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further.
As shown in Figure 1 and Figure 2, be the rigid suspended insulator protective cover of one that the utility model provides, this protective cover comprises: shield body 10, and, bolt and nut component protection department 20, this body 10 is fixedly connected to form discoid by two semicircular body by fastener 30, and it comprises:
Protective cover upper surface 11; Preferably, in embodiment, protective cover upper surface 11 has certain slope;
Protective cover shirt rim 12;
On protective cover upper surface 11, also interval arranges some rhones of separating by flange 13 14; Described flange 13 at protective cover upper surface along line direction setting, the long 230mm of high 7mm.
The connecting portion 15 being connected with channel-section steel, this connecting portion 15 mates the size of channel-section steel, and it is fixedly connected with by fixation kit with channel-section steel.
Preferably, in embodiment, described body 10 is fixedly connected with by two symmetrically arranged fasteners 30.
Preferably, in embodiment, on described fastener 30, (being fixedly connected with position) is also provided with Fixed latches 31, loosening to prevent two semicircular body above-below direction.
Preferably, in embodiment, described shield body 10 also comprises the reinforcement 16 that is arranged on connecting portion 15 places, to avoid body deformation.
As shown in Figure 3, for rigid suspended insulator protective cover of the present utility model is installed to mounting means and the design sketch on insulator.
Preferably embodiment more of the present utility model has chosen PA6M4(super-toughened nylon) as insulator protective cover material, its material all meets industry requirement from electric, mechanical, hot, physical property.
General rigid insulator diameter is 220mm, and protective cover diameter of the present utility model is about 270mm, is inconvenient to install too greatly; Too little, can not effectively protect again insulator.
