Abstract
The utility model relates to a bellows rain cover for a disconnecting switch. A bellows rain cover sleeving an ejector rod is comprised. An annular panel is arranged above the bellows rain cover. A plurality of through holes are distributed on the annular panel. The annular panel is further provided with a snap ring. The bellows rain cover passes through the through holes through bolts and locked under a platform on the ejector rod along with the snap ring. The annular panel of the bellows rain cover is shaped like a horn mouth of which the opening is upwards. The bellows rain cover is made from a pyrocondensation material. According to the device, the equipment quality and the equipment safe operation waterproof performance can be improved, the equipment service life can be prolonged, the equipment repair rate can be reduced, and the cost can be reduced.
Description
Technical field
The utility model relates to a kind of equipment assembling element that guarantees isolating switch safe operation in electric power system, especially a kind of for GW16(17) the bellows rain cover of type isolating switch.
Background technology
GW16(17) type isolating switch is applied very extensively in high-voltage system, belongs to single armed telescopic structure, must have reliable anti-water inlet measure.And in actual motion, on it, contact tube ubiquity watered and wetting and is caused the corrosion of its inner member, even cause spring breakage, cannot carry out normal breaking-closing operating.Corrosion has become the maximum hidden danger of isolating switch safe operation.For joint and the water inlet of bellows rain cover contact site of upper contact tube pinch rollers, the main method adopting is to seal with glass cement at present.
Summary of the invention
The problem that the utility model exists for above-mentioned prior art is made improvement, be that technical problem to be solved in the utility model is to provide a kind of bellows rain cover for isolating switch, can improve the anti-water inlet performance of equipment quality and equipment security of operation, the useful life of increase equipment, the maintenance rate of minimizing equipment, cost-saving.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of bellows rain cover for isolating switch, comprise the bellows rain cover being enclosed within on push rod, described bellows rain cover top is provided with annular panel, on described annular panel, be evenly equipped with several through holes, on described annular panel, be also provided with snap ring, described bellows rain cover passes through hole by bolt and is locked in together with snap ring under the platform on push rod.
Further, the annular panel of described bellows rain cover is opening up toroidal.
Further, described bellows rain cover is that material contracting with heat is made.
Compared with prior art, the utlity model has following beneficial effect: the utility model adds a bell-mouthed panel on bellows rain cover, by bolt lock on push rod, avoided the slip of bellows rain cover, and be provided with snap ring between push rod platform and bellows rain cover, strengthened steadiness, and bellows rain cover is that material contracting with heat is made, after heating, can be attached to closely on push rod, strengthen watertightness.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is the use state diagram of the utility model embodiment.
Fig. 2 is the organigram of the utility model embodiment.
Fig. 3 is the vertical view of Fig. 1.
In figure: 1-push rod, 11-platform, 2-bellows rain cover, 21-annular panel, 3-snap ring.
Embodiment
Embodiment mono-: as shown in Fig. 1 ~ 3, a kind of bellows rain cover for isolating switch, comprise the bellows rain cover 2 being enclosed within on push rod 1, described bellows rain cover 2 tops are provided with annular panel 21, on described annular panel 21, be evenly equipped with several through holes, on described annular panel 21, be also provided with snap ring 3, described bellows rain cover 2 passes through hole by bolt and is locked in platform on push rod 11 times together with snap ring 3.
In the present embodiment, for make rainwater can be smooth under, the annular panel 21 of described bellows rain cover is opening up toroidal.
In the present embodiment, for strengthening the watertightness of bellows rain cover, described bellows rain cover 2 is material contracting with heat making.
During use, snap ring 3 and bellows rain cover 2 are enclosed within on push rod successively, then use bolt locked, with hair dryer heating bellows rain cover, bellows rain cover is attached on push rod closely
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
