Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
A kind of structure of power locomotive top high-voltage electrical box provided by the invention is as depicted in figs. 1 and 2, including fixation
It is preceding in being provided with independent front end breaker 5 and rear end breaker 6 in the cabinet assembly 1 of power locomotive top, cabinet assembly 1
End breaker 5 and rear end breaker 6 are connected with high voltage ground switch 9 jointly.Front end breaker 5 is also connected with front voltage mutual inductance
Device 7, rear end breaker 6 are also connected with rear end voltage transformer 8, two voltage transformers respectively to power locomotive top before
End, rear end carry out voltage sampling, and the input terminal of front end breaker 5 is connected with the preceding inlet wire bridge joint electricity across 1 side wall of cabinet assembly
Cable assembly 2, the input terminal of rear end breaker 6 are connected with the rear inlet wire bridge cable assembly 3 across 1 side wall of cabinet assembly, contact
Online high-voltage electricity introduces the conducting rod of roof rear and front end by pantograph, and electric current passes through preceding inlet wire from preceding pantograph conducting rod
Bridge cable assembly 2 connect front end breaker 5 input copper bar, from rear pantograph conducting rod after inlet wire bridge cable assembly 3
It connects rear end breaker 6 and inputs copper bar, after the output end parallel connection of front end breaker 5 and rear end breaker 6 and across cabinet assembly 1
The outlet bridge cable assembly 4 of side wall is connected, and outlet bridge cable assembly 4 is separately connected the outer arrester of case and high-tension current mutual inductance
Device.Preceding inlet wire bridge cable assembly 2, rear inlet wire bridge cable assembly 3 and outlet bridge cable assembly 4 respectively with cabinet assembly
