Description
Technical field
The utility model relates to electric power system controller switching equipment, especially relates to a kind of inspection trolley for withdraw-type ac metal closing switch gear.
Background technology
Withdraw-type switch cabinet is in normal grid switching operation process, if the normal unlatching in switch cart push-on process of fixed contact metal dampers baffle plate puts in place or the upper and lower conductive arm naked of switch cart is protected, so just easily there are three relative ground circuits and cause the accident that operating personnel are injured.
Occur for fear of above-mentioned this situation, conventionally, before withdraw-type ac metal closing switch gear puts into operation, the valve unlatching situation of withdrawing switch apparatus is carried out an acceptance inspection; After putting into operation, in conjunction with preventive trial power failure chance, the valve unlatching situation of withdrawing switch apparatus is checked; In running, operating personnel run into the abnormal conditions such as operation clamping stagnation, and the valve unlatching situation of tackling if desired withdraw-type switch cabinet checks.
In order to realize examination and the inspection of above-mentioned three kinds of situations, the special inspection trolley that had many producer designs.But existing inspection trolley design is reasonable not, the visual field is too small, location is obvious not, and the intensity of contact arm is also inadequate.
Summary of the invention
In order to address the above problem, the utility model provides that a kind of visual field is wide, location obviously, high, the long service life withdraw-type ac metal closing switch gear inspection trolley of contact arm intensity.
The utility model for the technical scheme that its technical problem of solution adopts is:
Withdraw-type ac metal closing switch gear inspection trolley, comprise chassis vehicle, on described chassis vehicle, framework is installed, it is characterized in that: front side and the left and right sides of described framework are respectively arranged with observation window, the rear side of described framework is provided with upper and lower slot cover plate, on described upper and lower slot cover plate, be respectively arranged with three eradication edge contact arms, the installation site of described three eradication edge contact arms is corresponding with the position of switchgear bus connector.
As the further improvement of such scheme, the surrounding of described insulation contact arm is arranged with insulating sleeve, further ensures the fail safe of inspection trolley.
Wherein, described in be arranged on framework front side observation window cover whole framework front, expand visual range, can more clearly observe the situations the such as whether unlatching of valve and closed state and activity put in place.
As the further improvement of such scheme, described observation window is toughened glass observation window, adopts toughened glass can better protect staff's personal safety.
As the further improvement of such scheme, described chassis vehicle is provided with test position and two of service positions anchor point, have obvious work and test position can judge easily inspection trolley at mimic-disconnecting switch dolly the mode of operation in switchgear.
Wherein, the left and right sides of described framework is provided with baffle plate, and the observation window that is arranged on framework both sides is arranged on the both sides of baffle plate.
As the further improvement of such scheme, be at least provided with an illuminating lamp on slot cover plate above and/or under described, illuminating lamp can avoid insufficient light in equipment to cause observing unclear situation.
As the further improvement of such scheme, on described baffle plate, be at least provided with an illuminating lamp, the illuminating lamp of side can make the action situation of the clearer observation transmission mechanism for valve of staff.
The beneficial effects of the utility model are:
1, be respectively arranged with observation window in front side and the left and right sides of chassis vehicle framework, large area observation window, the convenient operate condition of observing upper and lower valve and transmission mechanism thereof;
2, contact arm adopts insulating material, and outsourcing insulating sleeve, increases the service life;
3, can under the state of closing the door, shake into shaking out dolly, real mimic-disconnecting switch mode of operation, has obvious work and test position, and judgement is simple;
4, observation window uses implosion guard to make, protection personal security.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, instead of whole embodiment, and those skilled in the art is not paying under the prerequisite of creative work, other designs and the accompanying drawing that can also obtain according to these accompanying drawings:
