Abstract
A handcart in a high-voltage switchgear comprises a handcart body and a fixed mounting plate and a handcart contact cylinder arranged on the handcart body, wherein a voltage transformer is arranged on the fixed mounting plate; a lower moving contact and an upper moving contact are arranged on the handcart contact cylinder; and the upper moving contact is connected with the voltage transformer through a fuse. Compared with the prior art, the voltage transformer is arranged at the top of the fixed mounting plate and above the upper contact and the lower contact of the handcart, therefore, the mounting stability of the voltage transformer is ensured; meanwhile, the handcart contact cylinder moves downward integrally, the weight distribution of the handcart is more uniform, therefore, the contact of the moving contact and a static contact is more uniform and reliable when the handcart is located at the running position.
Description
Technical field
The utility model relates to handcart in a kind of high voltage switchgear.
Background technology
In present 6～10KV electric power system, as power supplying and distributing equipment, metal-clad moveable formula high voltage switchgear is widely used.Majority all disposes handcart in its high voltage switchgear, by combination flexibly, can satisfy various requirements for scheme of electric power in the electric power system.
Isolate the introducing that handcart can be applicable to the electric power system power supply, make whole electric power system in maintenance, can form tangible cut-off point (fully guaranteeing maintainer's personal safety), as can satisfy the introducing of system power supply and the voltage detecting of incoming power simultaneously after installing voltage transformer (hereinafter to be referred as PT) additional.
Isolate the handcart scheme install voltage transformer additional, the contact arm of handcart and touch tube and account for 2/3 of whole handcart weight, the stress point that shakes into, shakes out because of handcart is handcart top, causes handcart to shake in switchgear into and crank occurs in the process; After dynamic and static contact interlock, occur unstable situation easily, cause because of uneven the burning of the dynamic and static contact contact of handcart three-phase.
The utility model content
The utility model technical issues that need to address provide handcart in a kind of high voltage switchgear, to reach rational in infrastructure, prevent because of the uneven purpose of burning of the dynamic and static contact contact of handcart three-phase.
In order to solve the problems of the technologies described above the technical solution of the utility model be, handcart in a kind of high voltage switchgear, comprise the handcart body, the mounting plate and the handcart that are arranged on the handcart body touch tube, described mounting plate is provided with voltage transformer, handcart touches tube and is provided with lower moving contact and last moving contact, and the described moving contact of going up is connected with voltage transformer by fuse.
Described voltage transformer is arranged on the top of mounting plate.
Also be provided with handcart on the described handcart body and shake into mechanism.
Described voltage transformer is connected by busbar with fuse, and the described moving contact of going up is connected by busbar with the fusing point device.
The utility model and prior art, the comparison with voltage instrument transformer is arranged on the top of mounting plate, the top of handcart upper contact head and following contact,, thereby guarantee the voltage transformer mounting stability; The while handcart touches an integral body and moves down, and makes that the distribution of weight on the handcart is more even, thereby the contact that guarantees handcart dynamic and static contact when run location is even more, reliable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further details;
Fig. 1 is the utility model structural representation;
In Fig. 1,1, voltage transformer; 2, fuse; 3, lower moving contact; 4, go up moving contact; 5, mounting plate; 6, handcart touches tube; 7, busbar; 8, handcart shakes into mechanism; 9, the handcart body.
Embodiment
Handcart in a kind of high voltage switchgear, comprise handcart body 9, the mounting plate 5 and the handcart that are arranged on the handcart body 9 touch tube 6, described mounting plate 5 is provided with voltage transformer 1, handcart touches tube 6 and is provided with lower moving contact 3 and last moving contact 4, and the described moving contact 4 of going up is connected with voltage transformer 1 by fuse 2.
Described voltage transformer 1 is arranged on the top of mounting plate 5.Be arranged on the top of moving contact 4 and lower moving contact 3, simultaneously handcart touched tube and 6 move down, the down-shift of working center of the voltage transformer 1 that makes has guaranteed the stability of voltage transformer 1.
Also be provided with handcart on the described handcart body 9 and shake into mechanism 8.Make things convenient for moving forward and backward of handcart.Mounting plate 5 selects for use high-quality 3mm cold-rolled steel sheet to make the intensity of mounting panel more reliable.
Described voltage transformer 1 is connected by busbar 7 with fuse 2, and the described moving contact 4 of going up is connected by busbar 7 with fusing point device 2.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection range of the present utility model.
