The invention provides a transformer on-load tap-changer hoisting device. The transformer on-load tap-changer hoisting device comprises a base, a supporting rod, a hoisting arm, a hoisting hook and ahoisting hook position adjusting mechanism. The base is used for being connected with a flange plate of an on-load tap-changer. The hoisting hook position adjusting mechanism comprises a first motor,a telescopic rod, a sliding rod, a fixed rod, a front pulley, a rear pulley and a second motor. The first motor is arranged at the tail end of the hoisting arm. One end of the telescopic rod is connected with the first motor, and the other end of the telescopic rod is connected with the sliding rod. The sliding rod is arranged at the front end of the hoisting arm in a sliding manner, is connectedwith the telescopic rod, and is provided with the front pulley. The fixed rod is arranged at the rear end of the hoisting arm and is provided with the rear pulley. The second motor is arranged on thesupporting rod and connected with the hoisting hook through a rope. The rope is supported on the front pulley and the rear pulley respectively. By means of the transformer on-load tap-changer hoistingdevice, hoisting inspection work in overhaul of the indoor transformer on-load tap-changer can be greatly facilitated, the hoisting inspection time is shortened, the problem that due to the narrow top space of an indoor transformer, hoisting cannot be carried out conveniently is solved, and then the work efficiency is improved.
Description
technical field [0001] The invention relates to a hoisting device for an on-load tap changer of a transformer, in particular to a hoisting device for an on-load tap changer of a power transformer that is suitable for installation and use above a large transformer. Background technique [0002] As an important voltage regulating device of the transformer, the on-load tap changer plays a vital role in the operation of the transformer. According to the requirements of the latest substation five-way connection, when the number of operations or the operating life of the on-load tap-changer reaches the value required by the manufacturer, the overhaul of the on-load tap-changer is required. For overhaul, the diverter switch of the on-load tap-changer needs to be hoisted out for inspection. At present, the commonly used method in equipment maintenance operations is to use a crane to lift. When the main transformer is located indoors, due to the large volume of the crane aerial wor...
