High-voltage combined falling switch on pole outdoor

In order to solve the hidden security danger brought because the prior outdoor high voltage drop-out switch is not provided with switching off and grounding structure, the invention provides an outdoor on-pole high voltage combined type drop-out switch. The switch has three-phase integration and combination structure, three-phase linked grounding switches are arranged at the load side of each phase, grounding moving blades matched with grounding static contacts communicated with static contacts at the load side of each phase are arranged on the grounding universal driving shafts of the three-phase linked grounding switches, universal driving shaft chain wheels matched with the locking and the unlocking of the grounding interlocking mechanism of each phase are also fixed on the grounding universal driving shafts, locking bars are connected and arranged, and driven shaft chain wheels matched with the locking and the unlocking of the universal driving shaft chain wheels are also arrangedon the connecting rods fo
