Description
Technical field
The utility model relates to the earthing test handcart, and is relevant with handcart with a kind of high-tension switch cabinet electrical verification earthing test especially.
Background technology
In existing city power distribution technical field, the middle high-voltage board is because of its compact conformation, and reliability is high and be used widely.But during work such as high-voltage board operation, scarce, the maintenance of disappearing, because of its charged position in valve, action need is very careful.
Maintenance at high-voltage board generally all has an earthing test handcart, as shown in Figure 1 and Figure 2, has two rows fixed contact 10 on the indoor wallboard of high-voltage board, and after circuit breaker cart withdrawed from, the valve that two row's fixed contact holes have two baffle forms hid it.Two valve are to control mobile respectively by valve connecting plate about the indoor left and right sides valve mechanism.Last valve connecting plate 20 is left behind to the next valve 40 that will descend, and exposes fixed contact hole down, and following valve connecting plate 30 upwards then will be gone up valve 50 and push to, and expose the upper static contact hole.
In when maintenance, push valve open with the electrical verification handcart earlier after, carry out electrical verification with the electrical verification rod then.After confirming no-voltage.Withdraw from the electrical verification handcart, with the ground connection handcart fixed contact is carried out ground connection again, guarantee maintenance safety.The electrical verification handcart only has the function of opening valve, and the ground connection handcart is that grounding function is arranged, and each operation all will be with two cars, every car belt fuser chassis special, and the cost height, and also very heavy, use very inconvenient.The high-voltage board breaker chamber overhead has certain altitude, needs many people to lift during detection, if lift to move is careless, safety problem also can cause the accident.
So the inventor redesigns out a kind of middle high-voltage board electrical verification earthing test handcart at the defective that is above-mentioned existence, this case produces thus.
The utility model content
The utility model provides a kind of middle high-voltage board electrical verification earthing test handcart, and structure is light and handy, and is easy to carry, is applicable to the cabinet of different in width.In addition, the utility model can also be realized collecting electrical verification and being grounded on one.
To achieve these goals, the scheme that the utility model adopted is:
Middle high-voltage board electrical verification earthing test handcart, the base plate of two symmetries, crossbeam bar, earth connection hack lever, wheel, valve compressing tablet about comprising; Base plate is the flap that has bending, comprises vertical portion and horizontal part, and the handcart wheel is installed below the lateral surface of vertical portion, and the valve compressing tablet of stirring wind is installed simultaneously; At the limit, upper end of vertical portion horizontal cross extended spot installation earth connection hack lever jack is set; Be connected and fixed with the crossbeam bar between two base plates.
Described floor level portion end has and raises up, and forms the bottom that step props up the crossbeam bar, supports.
Described valve compressing tablet is the L-square of band groove; L-square is fixed on the outside, base plate vertical portion.
Described valve compressing tablet has in the cell wall inboard valve guide wheel is carried out spacing triangle convex.
Described valve compressing tablet comprises the control switch last L-square of valve under the following L-square of valve and the control switch cabinet cashier's office in a shop.
Described earth connection hack lever is a character, two bending, and kink inserts jack, has the circular arc recess for electrical verification rod or earth rod placement on the hack lever.
Described crossbeam pole length satisfies middle high-voltage board 1000mm, 800mm and the wide requirement of 650mm cabinet, overhauls easy to carry.
After adopting such scheme, the utility model is compared with the traditional test handcart, have many beneficial effects: the utility model is that base plate and crossbeam bar are built, overall volume is dwindled greatly, can save the material about 70%, so both can save material cost, and can reduce the overall weight of handcart again significantly, lift to move is very convenient.And, just can be applicable to the cabinet of different in width as long as change the crossbeam bar.
The utility model can be pushed valve or following valve open or push upper and lower valve simultaneously open according to need of work easily.Possess auto-lock function after valve is pushed open, can carry out operations such as electrical verification, hanging earthing conductor.Such car is dual-purpose, and feature richness is without frequent transfer test handcart in electrical verification and the ground connection operation.And, just can be applicable to the cabinet of different in width as long as change the crossbeam bar, satisfied operating maintenance personnel work on the spot needs very expediently.
Figure of description
Fig. 1 is a high-tension switch cabinet doors structure schematic diagram;
Fig. 2 is the structural representation of test handcart in the prior art;
Fig. 3 is the front view of the utility model preferred embodiment;
Fig. 4 is the end view of the utility model preferred embodiment.
Embodiment
In conjunction with Fig. 3 and Fig. 4, the utility model preferred embodiment comprises base plate 1, crossbeam bar 2, earth connection hack lever 3, wheel 4, valve compressing tablet 5.
Valve compressing tablet 5 L-square structures comprise bottom land 51 and cell wall 52, and bottom land 51 is fixed on the outside of base plate vertical portion 11, two cell walls horizontal positioned about in the of 52, and its front portion exceeds bottom land 51, and outer respectively sticking up, and forms groove.Such design, be for when handcart propelling high-tension switch cabinet is indoor, the valve compressing tablet 5 that lower plate can be stuck up outward on the indoor valve mechanism is inducted on cell wall 52 and the bottom land 51, the valve mechanism upper plate is imported by last cell wall, control is moving of valve down, the valve mechanism lower plate is by cell wall importing down, and valve moves in the control.
In addition, valve compressing tablet 5 is that center line symmetry division along bottom land 51 comes in the present embodiment, can use flexibly as required like this, can certainly be one-body molded as required.Valve compressing tablet 5 has triangle convex 53 in cell wall 51 inboards simultaneously, and this triangle convex carries out spacing after pushing the switch cubicle valve open to the valve guide wheel, guarantees that operator and charged position keep the safe enough distance.
Operation principle of the present utility model needs electrical verification or ground connection when operation, and it is indoor that handcart is put into high-tension switch cabinet, promotes handcart forward along the direction of arrow of Fig. 4.When lower plate is run into valve compressing tablet 5 on the indoor valve mechanism, all be directed in cell wall 52 and the bottom land 51, so just realize the unlatching of valve up and down, carry out the operation of electrical verification or ground connection.The more traditional handcart structure of the utility model is lightly easy, is convenient for carrying and uses, and saves material cost significantly.
