Problems solved by technology
The function of the inner stays of the reactor is to isolate the coils of the coils. Because the reactor will vibrate during work, the inner stays will fall off. If the inner stays fall off seriously, it will directly cause a short circuit of each coil, and in severe cases, the reactor coils will be damaged. burn
The traditional method is to hit it with a wooden hammer to reset it. This method is inefficient, and sometimes the inner stays will be broken due to repeated knocking, and sometimes it cannot be reset because the hammering force is too small.
At the same time, this method resets slowly, and the reset effect is not good

The invention discloses an electric reactor inner supporting strip resetting tool. The electric reactor inner supporting strip resetting tool comprises a hand-cranking jack, a right-angle lifting rod and a support, wherein the right-angle lifting rod comprises the vertical portion and the transverse portion, the upper-end portion of the vertical portion is provided with a hole for the upper-end portion and the jacking-up end of the hand-cranking jack to be connected, the support comprises a connecting rod, two lantern rings are arranged at two ends of the connecting rod, the vehicle portion of the right-angle lifting rod can penetrate the lantern rings, the side portions of the lantern rings are provided with threaded holes for positioning, and a chute extending in the axial direction of the connecting rod is arranged at the upper end of the back portion of the connecting rod. The electric reactor inner supporting strip resetting tool is reasonable in design, simple and efficiency in operation and reliable in operation, meets the expected design requirement, can meet the operation requirements of different specifications of electric reactors, can be quickly dismounted and assembled and facilitates carrying of power transformer operation maintenance workers. The operation efficiency is greatly improved, and meanwhile an inner supporting strip is protected against damage due to hitting.
Description
technical field [0001] The invention relates to a live working tool, in particular to a tool for resetting inner stays of a reactor. Background technique [0002] The series reactor in the capacitor bank (which forms a resonant circuit) can limit the operating overvoltage, filter out the specified high-order harmonics, and at the same time suppress the amplification of other sub-harmonics, and reduce the voltage waveform distortion in the power grid. The function of the inner stays of the reactor is to isolate the coils of the coils. Because the reactor will vibrate during work, the inner stays will fall off. If the inner stays fall off seriously, it will directly cause a short circuit of each coil, and in severe cases, the reactor coils will be damaged. burn. The traditional method is to hit it with a wooden hammer to reset it. This method is inefficient. Sometimes the inner stays will be broken due to repeated knocking, and sometimes it cannot be reset because the hammeri...
