Abstract
The utility model relates to a kind of isolating switch rain cover, comprises casing, is cavity in casing, upper end is uncovered, and erectting at casing inner bottom surface has vertical rod, and vertical rod is socketed with knob and top cover, knob is connected with rain cover, and rain cover lower end is connected with cabinet exterior lower end.Owing to implementing technique scheme, the utility model can effectively prevent the extraneous water such as rainwater, snow-broth from being entered on auxiliary contact terminal by isolating switch rotation axis, and can rotate with rotation axis simultaneously, does not affect isolating switch and runs.
Description
Technical field
The utility model relates to a kind of rain shade device, particularly relates to a kind of isolating switch rain cover.
Background technology
In direct current system; direct current positive and negative electrode is insulation over the ground; any harm is not caused owing to not forming the path of earth current when generation one pole ground connection; but it is unallowed during a pole ground connection long-term work; because when ground connection occurs again another point of same one-level, the incorrect operation of signalling, relaying protection or control loop just may be caused.DC earthing is the common abnormal accident of electric power system, when especially running into bad weather, as rained, snowing, spring snow-broth melt, if water droplet is low will cause DC earthing on terminal board or binding post, and earth point not easy-to-search.Very large hidden danger is caused to power equipment.Outdoor isolation switches mechanism case the most easily causes DC earthing, the rotation axis of isolating switch is connected with its auxiliary contact, and the poor sealing between isolating switch rotation axis and auxiliary earth, when running into bad weather, the globule easily flows on auxiliary contact terminal will cause DC earthing along rotation axis.
Summary of the invention
The purpose of this utility model is that proposing a kind of extraneous water such as rainwater, snow-broth that prevents is entered isolating switch rain cover on auxiliary contact terminal by isolating switch rotation axis.
The purpose of this utility model is achieved in that isolating switch rain cover comprises casing, and be cavity in casing, upper end is uncovered, erect at casing inner bottom surface and have vertical rod, vertical rod is socketed with knob and top cover, knob is connected with rain cover, rain cover lower end is connected with cabinet exterior lower end.
Owing to implementing technique scheme, the utility model can effectively prevent the extraneous water such as rainwater, snow-broth from being entered on auxiliary contact terminal by isolating switch rotation axis, and can rotate with rotation axis simultaneously, does not affect isolating switch and runs.
Accompanying drawing illustrates: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is isolating switch rain cover structural representation;
Fig. 2 is isolating switch rain cover structural representation when packing up rain cover.
Legend: 1, vertical rod, 2, top cover, 3, threaded rod, 4, knob, 5, casing, 6, rain cover, 7, cover body, 8, axis hole, 9, perforation, 10, polished rod.
Embodiment:
The utility model by the restriction of following embodiment, can not determine concrete execution mode according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, isolating switch rain cover it comprise casing 5, be cavity in casing 5, upper end is uncovered, and erectting at casing 5 inner bottom surface has vertical rod 1, and vertical rod 1 is socketed with knob 4 and top cover 2, knob 4 is connected with rain cover 6, and rain cover 6 lower end is connected with casing 5 outer wall lower end.
Described casing 5 bottom surface perforate, tapping sets up vertical rod 1, offers axis hole 8 in bottom vertical rod 1.Isolating switch rotating shaft penetrates axis hole 8 by described tapping, thus casing 5 is connected with isolating switch.Isolating switch rotating shaft is connected with vertical rod 1 by key, common rotation.
Described vertical rod top is threaded rod 3, and bottom is polished rod 10.Threaded rod 3 is residing highly lower than casing 5 upper port bottom.When such setting can make knob 4 be in polished rod 10 place, can move up and down fast, save the operating time.Simultaneously after extraction rain cover 6, top cover 2 can be made to cover casing 5, prevent rainwater from entering casing 5.
Described casing 5 outer bottom is connected with cover body 7, offers perforation 9 in cover body 7 center.Because rain cover 6 adopts soft waterproof material to make, when rotating shaft stops operating, rain cover 6 wind-engaging easily inwardly folds, and for preventing rain cover 6 from snapping in rotating shaft place, sets up cover body 7.
During use, moved up by knob 4, until spin with threaded rod 3, extract rain cover 6 out, rain cover 6 naturally droops, masked isolation switch.Subsequently top cover 2 is fallen, cover casing 5 upper port.After starting isolating switch, axis of rotation, drive vertical rod 1, casing 5 are rotated, and the water fallen within rain cover 6 can throw away by the stressed outside expansion of rain cover 6 simultaneously.When not needing to use, rise top cover 2, knob 4 is fallen, then rain cover 6 is closed in casing 5, finally fall top cover 2.
Above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characteristic according to actual needs, meet the needs of different situations.
