Abstract
The utility model discloses a metal sheathed withdrawable high-pressure switch apparatus, comprising a breaker trolley, a guide rail of the breaker trolley and a main ground bar. The guide rail is provided with a ground copper bar, and a duck-billed ground contact is arranged between the breaker trolley and the ground copper bar. Compared with prior art, a static contact on the ground copper bar fits to the duck-billed ground contact of the breaker trolley because of the structure. The breaker trolley moves from a try state to a working state by a rocking mechanism, and the ground copper bar is tightly occlusive with the duck-billed ground contact, thereby greatly reducing contact resistance, ensuring safety of operators, and thoroughly satisfying electrically ground safety requirements of switch cabinets.
Description
Technical field
The utility model relates to high voltage switchgear, specifically, relates to a kind of metal-clad moveable formula high voltage switchgear.
Background technology
In the electric power system at present, the high-voltage switch gear in its metal-clad moveable formula high voltage switchgear mostly adopts joins the vacuum circuit-breaker dolly.But its switch earthing device, the structure more complicated has plenty of by the contacted mode of four wheels and cabinet on the circuit breaker dolly chassis, and this earthing mode earth resistance is very big, and operating personnel are constituted potential safety hazard.
The utility model content
Technical problem to be solved in the utility model is, a kind of metal-clad moveable formula high voltage switchgear is provided, and its objective is to realize the high-voltage switch gear safety ground.
For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of metal-clad moveable formula high voltage switchgear, comprise circuit breaker dolly, circuit breaker vehicle guide, the main ground connection row who is connected with cabinet, it is characterized in that: described guide rail is provided with guide rail ground connection copper bar, is provided with the duck-beak type grounding contact between described circuit breaker dolly and the guide rail ground connection copper bar.
A kind of metal-clad moveable formula high voltage switchgear, the middle part of described guide rail ground connection copper bar are provided with and the suitable fixed contact of duck-beak type grounding contact, being connected with the circuit breaker dolly chassis of duck-beak type grounding contact.
A kind of metal-clad moveable formula high voltage switchgear, described guide rail is connected by riveted joint with guide rail ground connection copper bar.
A kind of metal-clad moveable formula high voltage switchgear, described guide rail one end is provided with earth stud, and earth stud is connected with main ground connection row by flexible cord.
A kind of metal-clad moveable formula high voltage switchgear, owing to adopt said structure, compared with prior art, the fixed contact on the guide rail ground connection copper bar and the duck-beak type grounding contact of circuit breaker dolly cooperatively interact.The circuit breaker dolly is when shaking that into mechanism shakes the service position with it from test position, ground connection copper bar and duck-beak type grounding contact are interlocked closely, reduce contact resistance so greatly, further ensured operating personnel's safety, satisfied the electrical grounding safety requirements of switch cubicle fully.

Embodiment
As Fig. 1～shown in Figure 3, a kind of metal-clad moveable formula high voltage switchgear comprises circuit breaker dolly 1, circuit breaker vehicle guide 3, the main ground connection row 8 who is connected with cabinet, and described guide rail 3 is provided with guide rail ground connection copper bar 4.Be provided with duck-beak type grounding contact 2 between described circuit breaker dolly 1 and the guide rail ground connection copper bar 4.The middle part of guide rail ground connection copper bar 4 is provided with the fixed contact 9 suitable with duck-beak type grounding contact 2, and duck-beak type grounding contact 2 is connected with circuit breaker dolly 1 chassis.Guide rail 3 one ends are provided with earth stud 5, and earth stud 5 is connected with main ground connection row 8 by flexible cord.Switchgear front end mid portion is a circuit breaker dolly 1, it a duck-beak type grounding contact 2 each side has been installed.Left and right guide rail 3 links to each other with cabinet by construction bolt, guarantees that location hole matches on the guide locating device provided and contact box mounting panel of guide rail 3 front ends, and the handcart location hole of rear end matches with handcart location hole on the cabinet.Ground connection copper bar 4 on the guide rail 3 links to each other with steel plate by riveted joint, and earth stud 5 is connected with main ground connection row 8 by flexible cord.It is as follows so just to have formed a perfect ground path: circuit breaker duck-beak type grounding contact 2-guide rail ground connection copper bar 4-is flexible coupling-main ground connection row 8.Circuit breaker dolly in the switchgear is when shaking that into mechanism shakes the service position with it from test position, and the fixed contact 9 on the ground connection copper bar 4 is interlocked closely with duck-beak type grounding contact 2.
Vertical stretching at guide rail 3 opened an installing hole on the direction, ground connection copper bar 4 and steel plate are riveted together, and last guide plate 6, lower guide plate 7 are used for supporting the slider roller of circuit breaker dolly.
As shown in Figure 4,, install duck-beak type grounding contact 2 respectively, closely link to each other with the chassis car by two Φ 6 bolts in the and arranged on left and right sides of circuit breaker dolly chassis car for the circuit breaker dolly schematic diagram of the utility model switchgear.
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.
