The utility model discloses an overhauling bracket of disconnector has solved the low scheduling problem of maintenance efficiency because of using the crane to result in when examining and repairing isolator. Including support fixation clamp, support column, crossbeam and hoist and mount pulley, the support fixation clamp presss from both sides tightly on switch base's channel -section steel, and support column and crossbeam are propped simultaneously to the support fixation clamp, then utilizes the support to isolator without lifting an eyebrow of hoist and mount pulley to found the bottle and hoist to reaching and improving labor efficiency, alleviate intensity of labour, reduce the purpose of potential safety hazard, support mounting convenient operation is nimble, has very high use value.
