Problems solved by technology
The function of the inner stays of the reactor is to isolate the coils of each coil. 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 burned.
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

Embodiment 1
[0023] A method for resetting inner stays in a reactor, which requires the use of a hand jack 1, a right-angle lifting rod 2 and a bracket 3, the right-angle lifting rod includes a vertical part 21 and a horizontal part 22, and the upper end of the vertical part is provided with The hole 211 connected to the jacking end of the hand jack, the support 3 includes a connecting rod 31, and two sections of collars 32 are arranged at both ends of the connecting rod, and a hook is respectively arranged on the two collars. Groove 33, the hook grooves on the two collars stand opposite each other, the upright portion of the right-angle lifting rod can pass through the collars of these two sections, and the side of the collar is provided with a threaded hole 321 for positioning. The upper end of the back is provided with a chute 311 extending axially along the connecting rod. The upright part of the right-angle lifting rod is a cylindrical body, so as to facilitate matching with the colla...

The invention discloses an electric reactor inner supporting strip resetting method. The electric reactor inner supporting strip resetting method utilizes a hand-cranking jack, a right-angle lifting rod and a support to perform resetting, enabling the right-angle lifting rod to penetrate two lantern rings of the support and then locking the right-angle lifting rod with screws, connecting the jacking-up end of the hand-cranking jack with the upper end of the vertical portion of the right-angle lifting rod through a hole at the upper end and a bolt, enabling the supporting end of the hand-cranking jack to be supported in a chute of the support and positioning the supporting end through a connector, assembling an electric reactor inner supporting strip resetting tool and then utilizing upper and lower hook grooves formed in the support to hook the tool onto the upper end and the lower end outside an insulating package of an electric reactor, enabling the transverse portion of the right-angle lifting rod to press a dropped inner supporting strip, and pressing the dropped inner supporting strip in place by shaking the hand-cranking jack. A traditional method for resetting the inner supporting strip by adopting wooden hammer hitting is thoroughly changed, the operation efficiency is greatly improved, and meanwhile the inner supporting strip is protected against damage due to hitting.
Description
technical field [0001] The invention relates to a maintenance method for a reactor inner stay, in particular to a method for resetting an inner stay for a reactor. [0002] Background technique [0003] 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 each coil. 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 burned. . 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, a...
