Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

According to the safety auxiliary device for the power distribution cabinet to be connected into the power generation car, based on the fact that the axial length of the first insulating rod 10 is adjustable, the first insulating rod 10 can be flexibly arranged according to the arrangement position of the busbar 51 in the power distribution cabinet 50 in the using process, and therefore the first insulating rod 10 and the busbar 51 accurately correspond to each other as shown in fig. 9. No matter the busbar 51 is arranged on the side wall or the top wall of the power distribution cabinet 50, the first insulating rod 10 and the busbar 51 can be accurately and effectively installed correspondingly. And the cable 60 on the busbar 51 is supported and fixed by the cable fixing member 13 on the first insulating rod 10, so that even if there is drag during operation, the drag force is transmitted from the cable fixing member 13 to the first insulating rod 10 and not to the busbar 51. The first insulating rod 10 bears the dragging force, so that the connection reliability between the cable 60 and the busbar 51 is effectively guaranteed, and the cable 60 is prevented from falling off or the wiring lug on the busbar 51 is prevented from being damaged.
For example, when the busbar 51 is disposed on the top wall of the power distribution cabinet 50, there is no suitable support structure below the busbar 51 to support and fix the cable 60, so that the cable 60 may fall off and the busbar 51 may be damaged. The first insulating rod 10 in the scheme can be tightly abutted against two side walls of the power distribution cabinet 50 respectively, stretches across between the two side walls of the power distribution cabinet 50 and is fixed below the busbar 51, so that the cable 60 is fixedly supported, and the cable 60 and the busbar 51 are effectively protected.
