The utility model relates to a trolley operating handle for a transformer substation, and belongs to the technical field of substation operation equipment. The technical scheme is that: the trolley operating handle comprises an extension rod (1), a stabilization handle (2) and a handle (3), wherein the extension rod is arranged on the end part of the handle; the stabilization handle is arranged on the extension rod; and the extension rod has a detachable structure. The trolley operating handle has the advantages that the detachable extension rod is arranged on the trolley operating handle, and the stabilization handle is arranged on the extension rod to prevent the extension rod from wobbling to and fro during operation, so that scratching with an insulating glove during the operation can be avoided, and a trolley can be stably operated. The trolley operating handle is wide in application range, universal for all transformer substations employing trolleys with a model number of KYN28A-12, simple in structure, convenient to manufacture, popularize and use, and low in cost; and the problem of the scratching with the insulating glove is radically solved.
