Withdrawable circuit breaker is a kind of in the omnipotent breaker, is characterized in having the drawer type mounting structure.Withdrawable circuit breaker is when work, circuit breaker drawer base and breaker body must guarantee to be electrically connected good, the electrical connection of circuit breaker drawer base and breaker body be by the busbar system finish promptly by be arranged on the bridge-shaped contact on the circuit breaker drawer base and be arranged on the breaker body after connect the busbar clamping and realize.
The structure of the busbar system of traditional withdrawable circuit breaker as shown in Figure 1, connect after being arranged on the connecting plate of busbar barb with connect being electrically connected of busbar and bridge-shaped contact after thereby rectangular-shaped draw-in groove clamping on being arranged on described bridge-shaped contact realizes, the problem that adopts said structure to exist is: the contact-making surface that connects busbar and bridge-shaped contact after () is little, contact resistance is big, causes the circuit breaker temperature rise too high; (2) on the drawout chassis after connect bridge-shaped contact clamping on busbar and the drawout chassis after, because of nonstandard in being transported " falling ", " side ", " rolling " operation, after connect busbar and separate with bridge-shaped contact easily.
The utility model content
This practical technical problem to be solved be the bridge-shaped contact that exists in the busbar system of conventional drawer formula circuit breaker with after connect that busbar causes because of contact-making surface is little that contact resistance is big, temperature rise and both segregative problems.
The technical scheme that realizes the utility model purpose is:
A kind of busbar system of withdrawable circuit breaker, on comprising the bridge-shaped contact that is arranged on the circuit breaker drawer base and being arranged on breaker body and with snap fit be connected with described bridge-shaped contact after connect busbar;
Connect busbar after described and comprise mounting panel and at least one connecting plate that is connected with mounting panel; The two ends of described bridge-shaped contact are provided with two groups of contact chips that be arranged in parallel; The both sides of described connecting plate form Ka Tai or draw-in groove, the inboard of each winding contact form with connecting plate on the corresponding clamping of card platform draw-in groove or with connecting plate on the Ka Tai of the corresponding clamping of draw-in groove;
Described draw-in groove is a circular groove, and described Ka Tai is the arc cam that is complementary with circular groove.
In the technique scheme, described mounting panel and described connecting plate are formed in one.
In the technique scheme, the homonymy of described mounting panel is connected with two connecting plates that be arranged in parallel.
In the technique scheme, every winding contact constitutes by the multi-disc contact chip is superimposed.
The utlity model has positive effect:
(1) in the utility model, the Ka Tai of circular arc and the draw-in groove of circular arc carry out clamping can guarantee that both have enough big contact area, thereby makes contact resistance little, also just can not cause the circuit breaker temperature rise too high; In addition because the Ka Tai of circular arc and the draw-in groove of circular arc can swing when the clamping state within the specific limits, thereby after connect busbar and bridge-shaped contact is difficult for being separated by force.
(2) in the utility model, the homonymy of described mounting panel is connected with two connecting plates that be arranged in parallel; Adopt said structure when reality is used, the quantity that can increase bridge-shaped contact with after connect busbar and be connected, thereby the increase contact-making surface has further been eliminated the problem of temperature rise, the while has also increased ampacity.
