Abstract
A bus connecting device of a high-voltage switch device comprises a breaker, an upper end copper bar connected with the upper terminal of the breaker, and a lower end copper bar connected with the lower terminal of the breaker, wherein the upper end copper bar is connected with the lower end copper bar through a connecting sheet. The connecting sheet is a copper connecting sheet, copper flexible connection can flexibly and effectively compensate tension produced by electromotive force; and with the flexibility of the copper flexible connection, the tension produced by electromotive force can be effectively compensated, meanwhile, the device can be compensated operatively, and the test, overhaul and the like of the device also can be facilitated.
Description
Technical field
The utility model relates to a kind of high voltage switchgear bus connecting device.
Background technology
In present high-voltage system, as power supplying and distributing equipment, metal fixed high-voltage switch equipment is widely used with characteristics such as its flexible operation, maintenance convenience, primary elements such as its high voltage switchgear internal breaker, isolation switch and instrument transformer all fixedly mount, and couple together by bus between each element.In running on big electric current operating mode, the contact performance of circuit breaker upper and lower side bus junction is to the stable decisive role of whole system, the contact of the bus junction of circuit breaker upper and lower side is bad at present, influenced the stable operation of whole system, under by big current conditions, because electrodynamic effect can make the contact-making surface of upper and lower end of circuit breaker stressed, may cause the circuit breaker heating even burn.
The utility model content
It is good with the contact performance of the bus junction that reaches the circuit breaker upper and lower side that the utility model technical issues that need to address provide a kind of high voltage switchgear bus connecting device, guarantees the purpose of system stable operation.
In order to solve the problems of the technologies described above the technical solution of the utility model be, a kind of high voltage switchgear bus connecting device, comprise circuit breaker, the upper end copper bar that is connected with the circuit breaker upper terminal, the lower end copper bar that is connected with the circuit breaker lower terminal, described upper end copper bar is connected by brace with the lower end copper bar.
The two ends of described brace are provided with connecting hole.
Described brace is an arch.
The two ends of described brace are connected with the lower end copper bar with the upper end copper bar by bolt respectively.
The utility model compared with prior art, brace is the copper brace, copper its scalability that is flexible coupling can remedy effectively because the tension force that electric power produces, the scalability that utilizes copper to be flexible coupling, effectively remedy the tension force that produces owing to electric power, simultaneously equipment is played work compensation, make things convenient for effects such as the test of equipment and maintenance.
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, the upper end copper bar, 2, the lower end copper bar, 3, brace, 4, bolt.
Embodiment
As shown in Figure 1, a kind of high voltage switchgear bus connecting device comprises circuit breaker, the upper end copper bar 1 that is connected with the circuit breaker upper terminal, and the lower end copper bar 2 that is connected with the circuit breaker lower terminal, described upper end copper bar 1 is connected by brace 3 with lower end copper bar 2.
The two ends of described brace 3 are provided with connecting hole.
Described brace 3 is an arch.
The two ends of described brace 3 are connected with lower end copper bar 2 with upper end copper bar 1 by bolt 4 respectively.
Described brace 3 is the copper brace, copperly is flexible coupling, and its scalability can remedy effectively because the tension force that electric power produces.The scalability that utilizes copper to be flexible coupling, effectively remedy the tension force that produces owing to electric power, brace 3 is an arch, when brace 3 stretches because of the tension force that electric power produces, avoided copper bar directly to connect the copper bar distortion of generation, simultaneously equipment is played work compensation, make things convenient for effects such as the test of equipment and maintenance.
