Chinese patent CN201310409700.1 discloses a kind of sandwich type line side cabinet on roof of electric locomotive, and net sidecar is strengthened composite by resin-base glass fibre and makes, the high voltage equipment on protection of electrical locomotive roof；Described sandwich type line side cabinet on roof of electric locomotive includes protective cover and protective cover；With the Flange joint on power locomotive top lid on the downside of described protective cover, it is connected with described protective cover on the upside of described protective cover.The technical solution of the utility model; the deficiencies in the prior art can be made up; high-voltage line equipment on power locomotive top is effectively protected; place haze the high voltage equipment of power locomotive top is damaged; avoid electric discharge and non-inductive net pressure phenomenon; effectively protect high pressure equipment or the contact net lines of power locomotive top, strengthen the traffic safety of locomotive.
Above-mentioned patent equipment in cabinet be replaced or get off inspection time, all must hang open the top cover at cabinet top, hanging out from cabinet top to interior equipment, part net sidecar just can carry out the lifting of equipment in cabinet after even whole net sidecar being hung out locomotive, very inconvenient again.
Utility model content
Being difficult to the problems such as lifting, replacing to solve cabinet inner high voltage equipment, this utility model aims to provide a kind of electric locomotive net sidecar, and this net sidecar, by this net sidecar and supporting cap structure, can realize lifting outside equipment car in cabinet, thus improve overhaul efficiency.
To achieve these goals, this utility model be the technical scheme is that
A kind of electric locomotive net sidecar, including net sidecar body, it is characterised in that have the top cover hole outside equipment hangs out net sidecar in by net sidecar at the top of net sidecar body, this net sidecar body is removably secured the top cover cover plate mated with this top cover hole.
During thus, it is desirable to install or hang out the equipment in net sidecar, dismantle top cover cover plate, can be operated by top cover hole, simple and convenient.
According to embodiment of the present utility model, it is also possible to make this utility model further to optimize, below for the technical scheme formed after optimizing:
Observe situation in cabinet for convenience, equipped with the observation window being made of clear material on described net sidecar body and/or top cover cover plate.Observation window should be the least, is preferably made up of glass.
In order to avoid electromagnetism leaks from observation window, with electromagnetic shielding net on described observation window.
It is provided with sealing strip between described net sidecar body and top cover cover plate.Preferably, described sealing strip is the rubber strip of band electromagnetic shielding net.Thus, the mode that net sidecar top and top cover junction use rubber strip crimp realizes and the docking of top cover, and rubber strip can install additional metallic shield net or other have the material of shield effectiveness, it is ensured that guarantee effectiveness while top cover and net sidecar slitless connection.
On described top cover cover plate, at least one hv cable termination is installed.
Described net sidecar body and/or top cover cover plate are provided with access hole or door, and this access hole or door are provided with conduction lining cloth, and equipped with high voltage safe cross-linked structure on access hole or door.Thus, access hole or door local overhauling and maintenance, access hole or the door of equipment in cabinet strictly protects, and carries out electromagnetic protection, access hole or door need to carry out high voltage safe cross-linked protection by installing the modes such as conduction lining cloth additional.
The top of described net sidecar body, equipped with cap base flange, is provided with mounting flange, is fixedly linked by securing member between cap base flange and the mounting flange of top cover cover plate of described net sidecar body bottom described top cover cover plate.
In order to ensure the sealing effectiveness of the sealing strip being arranged between cap base flange and mounting flange, the width of described cap base flange is more than the width of mounting flange.Thus, the flange in the bottom that cap base is docked with net sidecar suitably does width, it is ensured that net sidecar top rubber bar dock with base board flange after scalable amount, it is ensured that sealing effectiveness.
Equipped with the photographic head of machine operation in monitoring cabinet in described net sidecar body.Thus, can in monitoring cabinet by the way of installing photographic head additional in cabinet equipment situation.
By said structure, electric locomotive net sidecar of the present utility model uses new-type net sidecar structure and supporting cap structure, achieve the outside dismounting of net sidecar high pressure equipment between machinery, reduce the impact that electromagnetic environment in car is caused by cabinet inner high voltage equipment, it is achieved the Real Time Observation of equipment significant points in cabinet simultaneously.
Compared with prior art, the beneficial effects of the utility model are:
1) current net sidecar top and roof top cover excesssive gap, the problem that there is potential safety hazard are solved by the slitless connection of net sidecar top rubber bar Yu cap base flange.
2) by this net sidecar and supporting cap structure, it is achieved lift outside equipment car in cabinet, overhaul efficiency is improved.
3) in the observation window of necessity, cabinet, photographic head and access hole or door can assist daily maintenance and maintenance work, reduce the frequency opening top cover cover plate, it is achieved Quick overhaul is safeguarded.
