The utility model content
Technical problem to be solved in the utility model just provides a kind of switch cubicle that is beneficial to the bus heat radiation, can realize the good heat radiating of bus in the switch cubicle.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of switch cubicle that is beneficial to the bus heat radiation, comprise cabinet and be installed on the interior frame-type circuit breaker of cabinet, horizontal bus and the vertical bus with three-phase phase line, described horizontal bus is positioned at the frame-type circuit breaker top, horizontal bus links to each other with the end of incoming cables of frame-type circuit breaker and the leading-out terminal of frame-type circuit breaker through vertical bus, one end of described vertical bus has the connecting portion phase line that links to each other with the three-phase phase line of vertical bus respectively, the end of incoming cables of described frame-type circuit breaker links to each other with vertical bus through the connecting portion phase line with the leading-out terminal of frame-type circuit breaker, wherein phase line of described connecting portion phase line bends up or down with respect to other two phase lines of connecting portion phase line, form the kink phase line, other two phase lines of this kink phase line and connecting portion phase line are separated by and are formed the gap.The clearance space that forms by the connecting portion phase line to dispel the heat for bus.
On the basis of the above, the utility model can be done following improvement:
Kink phase line described in the utility model is between other two phase lines of connecting portion phase line.
Other two phase lines of connecting portion phase line described in the utility model are horizontally disposed with.
The end of incoming cables of circuit breaker described in the utility model is positioned at the leading-out terminal top, the kink phase line that is connected with the end of incoming cables is with respect to the upwards bending of other two phase lines of connecting portion phase line, and the kink phase line that is connected with leading-out terminal bends downwards with respect to other two phase lines of connecting portion phase line.
Compared with prior art, the utility model technology has following beneficial effect:
(1) vertical bus of the present utility model is connected with frame-type circuit breaker by the connecting portion bus, connecting portion phase line at vertical bus one end is provided with the gap that is bent to form, it is the radiation that the kink phase line has been avoided other two-phase phase line effectively, and two bundle connecting portion phase line also in the vertical direction certain distance is arranged, make that the cold air of bottom of cabinet bulk can be in a large number and flow through the portion's phase line that respectively is connected smoothly, thereby formed favorable cooling effect, be beneficial to the heat radiation of the connecting portion phase line of three-phase, thereby guarantee the service behaviour of vertical bus, also guaranteed safety;
(2) setting of the utility model kink phase line is applicable to the switch cubicle of small size, meets the miniaturization designing requirement;
(3) the utility model need not to increase specification or the sectional area of bus, and a phase line by bending has simply then realized the good heat radiating of vertical bus, and is simple in structure, heat radiation is with low cost.
