Abstract
The invention relates to a disconnectable switch cabinet of a busbar connection portion. The switch cabinet comprises a switch cabinet body and a dolly switch. The switch cabinet also comprises a linkage mechanism and a stroke switch. A switch cabinet busbar is arranged in the switch cabinet body. One end of the switch cabinet busbar is connected to a grounding busbar through the stroke switch and the other end is connected to the dolly switch. The dolly switch is connected to the stroke switch through the linkage mechanism. When the dolly switch is pushed to an overhauling position, a linkage mechanism drives the stroke switch to disconnect the connection between the switch cabinet busbar and the grounding busbar. Compared to the prior art, by using the switch cabinet of the invention, the switch cabinet busbar and the grounding busbar are designed to be connected through the stroke switch; through the linkage mechanism, when the dolly switch is pushed to the overhauling position, the stroke switch automatically disconnects the connection between the switch cabinet busbar and the grounding busbar so that a personal safety accident generated because work personnel opens an isolation baffle plate without permission is avoided.
Description
Technical field
The present invention relates to secured electrical technology, especially relating to a kind of busbar connecting portion can breakaway-element switch cubicle.
Background technology
Recent years, in electric power system, a lot of switch cubicle occurs and to get an electric shock the human casualty accident caused, electric shock reason is because staff touches switch cabinet electrified part and causes by mistake mostly.Between switch cubicle turn(a)round, switch cabinet handcart switch shakes to maintenance position, isolate baffle plate after switch cubicle will reliably close on request, but in maintenance process, may be for various reasons, staff may separate isolation without authorization, in current switch cubicle, car switch is positioned at before switch cubicle, busbar and be positioned at after switch cubicle with the fixed contact that busbar is bolted to connection, two parts are isolated by isolation baffle plate, when car switch is pulled to maintenance position, pass through mechanical linkage, isolation baffle plate will become closed condition from open mode, isolation baffle plate busbar below still continues to be connected with fixed contact, retainer belt electricity condition.Because the car switch contact after isolation baffle plate is directly fixed on busbar, if bus is charged, then this contact is always charged.When such people is for opening isolation baffle plate, the fixed contact after staff just likely touches baffle plate causes getting an electric shock, and causes personal injury.
Summary of the invention
Object of the present invention is exactly provide a kind of busbar connecting portion can breakaway-element switch cubicle to overcome defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A kind of busbar connecting portion can breakaway-element switch cubicle, comprise switch cabinet body and car switch, described switch cubicle also comprises link gear and travel switch, switch cabinet busbar in described switch cabinet body, one end of described switch cabinet busbar is connected with ground connection busbar by travel switch, the other end is connected with car switch, and described car switch is connected with travel switch by link gear;
When described car switch is pushed into maintenance position, link gear drives the connection between travel switch cut-off switch cabinet busbar and ground connection busbar.
Described car switch is provided with the contact for connecting switch cabinet busbar.
Described contact is provided with three altogether.
Described car switch comprises connecting rod, and described contact is fixed on car switch by connecting rod.
The two ends of described row link gear are connected with travel switch and connecting rod respectively.
Compared with prior art, the present invention has the following advantages:
1) by designing the switch cabinet busbar and ground connection busbar that are connected by travel switch, and realize when car switch is pushed into maintenance position by link gear, connection between travel switch automatic cut-off switch cabinet busbar and ground connection busbar, this avoid the personal safety accident caused after staff opens isolation baffle plate without authorization.
2) contact can make the connection between car switch and switch cabinet busbar and disconnect more flexible.
3) quantity of contact is three switch cubicles that three-phase can well be coordinated electric.
4) connecting rod can improve the stability of connection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein: 1, car switch, 2, contact, 3, close cabinet cabinet, 4, switch cabinet busbar, 5, travel switch, 6, ground connection busbar, 7, link gear, 8, connecting rod.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.The present embodiment is implemented premised on technical solution of the present invention, give detailed execution mode and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
A kind of busbar connecting portion can breakaway-element switch cubicle, as shown in Figure 1, comprise switch cabinet body 3 and car switch 1, switch cubicle also comprises link gear 7 and travel switch 5, switch cabinet busbar 4 in switch cabinet body 3, one end of switch cabinet busbar 4 is connected with ground connection busbar 6 by travel switch 5, and the other end is connected with car switch 1, and car switch 1 is connected with travel switch 5 by link gear 7;
When car switch 1 is pushed into maintenance position, link gear 7 drives the connection between travel switch 5 cut-off switch cabinet busbar 4 and ground connection busbar 6.
Car switch 1 is provided with the contact 2 for connecting switch cabinet busbar 4, and contact 2 is provided with three altogether.
Car switch 1 comprises connecting rod 8, and contact 2 is fixed on car switch 1 by connecting rod 8, and the two ends of row link gear 7 are connected with travel switch 5 and connecting rod 8 respectively.
Originally single busbar is mainly carried out partition type design by switch cubicle of the present invention, the switch cabinet busbar 3 connected instead by travel switch 5 and ground connection busbar 6, and realize by link gear 7 interlock that travel switch 5 and car switch 1 move and design, thus when making car switch 1 be pulled to maintenance position to the right by test position, while switch cabinet busbar 4 and contact 2 disconnect, travel switch 5 also disconnects, therefore no longer charged on switch cabinet busbar 4, thus forms a kind of safer switch cubicle.
