when the coil mechanism 7 is needed to be increased, the driving seat 909 is started positively, the output shaft of the driving seat 909 drives the threaded rod 908 to rotate positively, the threaded rod 908 drives the connecting block 907 to move to one side of the second conduit 903, the connecting block 907 drives the sliding cover 906 to move to one side of the second conduit 903, the sliding cover 906 drives the plug plate 911 to move to one side of the second conduit 903, the plug plate 911 presses the third pressure-variable oil inside the hydraulic shell 901 and close to one side of the second conduit 903 to flow between the upper part of the inner cavity of the shell 1 and the lower part of the top plate 4 through the second conduit 903, meanwhile, the first pressure-variable oil at the bottom of the inner cavity of the shell 1 flows into one side of the hydraulic shell 901 close to the first conduit 902 through the first conduit 902, at this time, the height of the first pressure-variable oil at the bottom of the inner cavity of the shell 1 is reduced, the position of the second pressure-variable oil is moved downwards until the second pressure-variable oil does not have the coil mechanism 7 at the uppermost part of the lower part of the upright 5, at this time, because the overall density of the coil mechanism 7 is smaller than that of the second variable-pressure oil and the third variable-pressure oil, the coil mechanism 7 immersed in the second variable-pressure oil floats upwards along the outer side of the upright 5 until contacting with the lowest coil mechanism 7 at the upper part of the upright 5, at this time, the contact block 703 on the lowest coil mechanism 7 at the upper part of the upright 5 is inserted into the inside of the socket 704 on the upper surface of the upward-floating electric coil mechanism 7 to contact with the wire guide plate 702 on the upward-floating electric coil mechanism 7, at the same time, the limit block 602 contacted with the upward-floating electric coil mechanism 7 is extruded by the upward-floating electric coil mechanism 7 to shrink into the inner cavity of the mounting groove 502, the potential mechanism 8 moves downwards by one lattice, the contact plate 705 on the inner side of the upward-floating electric coil mechanism 7 contacts with the adjacent limit block 602, at this time, the topmost electric coil mechanism 7 contacts with the original electric coil mechanism 7, the upward-floating electric coil mechanism 7, the limiting mechanism 6 and the potential mechanism 8 contacted with the floating electric coil mechanism 7 form a complete closed fall, so that the number of coil mechanisms 7 which participate in work on the upper part of the upright post 5 is increased;
when the number of coil mechanisms 7 above the upright post 5 needs to be reduced, the driving seat 909 is reversely started, the driving seat 909 drives the plug plate 911 to move towards one side close to the first guide pipe 902 through the threaded rod 908, the connecting block 907 and the sliding cover 906 in sequence, the plug plate 911 presses the first pressure-variable oil inside the hydraulic shell 901 at one side close to the first guide pipe 902 to flow into the bottom of the inner cavity of the shell 1 through the first guide pipe 902, meanwhile, the third pressure-variable oil at the top end of the inner cavity of the shell 1 flows into one side close to the second guide pipe 903 through the second guide pipe 903, at the moment, the height of the first pressure-variable oil at the bottom of the inner cavity of the shell 1 rises, the position of the second pressure-variable oil moves upwards until the first pressure-variable oil is immersed in the coil mechanism 7 at the lowest upper part of the upright post 5, at the moment, because the overall density of the potential mechanism 8 is smaller than that of the second pressure-variable oil, the potential mechanism 8 floats upwards to the middle position of the second variable-pressure oil and the third variable-pressure oil, meanwhile, because the overall density of the coil mechanism 7 is higher than that of the first variable-pressure oil, the lowest coil mechanism 7 at the upper part of the upright post 5 moves downwards to be combined with the coil mechanism 7 at the lower part of the upright post 5, then the driving seat 909 is started forward to enable the second variable-pressure oil to return to the middle part of the upper coil mechanism 7 group of the upright post 5 and the lower coil mechanism 7 group of the upright post 5, at the moment, the potential mechanism 8 falls back, and because the density of the potential mechanism 8 is higher than that of the third variable-pressure oil, the potential mechanism 8 contacts with the limiting mechanism 6 contacted with the lowest coil mechanism 7 at the upper part of the upright post 5, the upper surface of the limiting block 602 on the limiting mechanism 6 at the next grid of the lowest coil mechanism 7 at the upper part of the upright post 5 contacts with the lower surface of the potential mechanism 8, and the potential mechanism 8 is limited to fall, at the moment, the electric coil mechanism 7 at the upper part of the upright post 5 is, the limiting mechanism 6 and the potential mechanism 8 contacted with the coil mechanism form a complete closed fall, so that the number of the coil mechanisms 7 which participate in work on the upper part of the upright post 5 is reduced, the number of coils on the upright post is directly changed, the transformation range of the transformer is improved, and a plurality of coils are avoided. The problem of current transformer vary voltage fixed is solved.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
