The stabilizing plate 709 is connected to the inner wall of the mounting cylinder 707 through bolts. The upper side of the mounting cylinder 707 is connected to a support frame 712 through bolts. Both ends of the support frame 712 away from the mounting cylinder 707 are rotatably connected to guide rollers 713 through bearings. The outer side of the thin rope 703 is in contact with the outer sides of the two guide rollers 713. The inner wall of the mounting cylinder 707 is provided with two symmetrical grooves. The same floating box 720 is slidably connected in the two grooves. The side of the floating box 720 close to the guide frame 708 is rotatably connected to an inclined plate 719 through a bearing, and the inclined plate 719 is away from the floating box 720. A U-shaped frame 718 is connected to one side by bolts, and a stopper 721 is connected to the upper side of the U-shaped frame 718 by bolts; two symmetrical circular openings are opened on the outside of the guide frame 708, and the inner walls of the two circular openings are rotatably connected to the inner wall of the U-shaped frame 718 through bearings, and a stopper 722 is connected to the side of the connecting rod 710 close to the floating box 720 by bolts, and the bottom of the stopper 722 contacts the outside of the stopper 721, and the stopper 722 is located above the stopper 721, and the upper side of the connecting rod 710 is connected to a connecting plate 714 by bolts, and a rectangular opening 715 is opened on the connecting plate 714, and a rectangular opening 715 is provided inside A pull rod 716 is provided, and the outside of the pull rod 716 is clamped with the outside of the connecting plate 714; a hole groove is opened on the upper side of the pull rod 716, and the inner wall of the hole groove is rotatably connected with an adjusting bolt 717 through an external thread, and the upper side of the adjusting bolt 717 is rotatably connected with the end of the thin rope 703 away from the float 704 through a bearing, and fine holes are opened on the bottom inner wall of the accommodating box 4 and the upper side of the box body 1, and the inner walls of the two fine holes are connected with the same isolation tube 702 through bolts, and one end of the thin rope 703 connected to the float 704 passes through the isolation tube 702 and enters the box body 1, and the bottom of the float 704 is connected with a counterweight block 705 through bolts.

[0029] Specifically, after the transformer oil in the box body 1 is consumed to a certain extent, the oil level drops, and the float 704 connected to the counterweight block 705 can no longer float, so that the counterweight block 705 pulls the thin rope 703 to make the thin rope 703 tight. Under the gravity of the counterweight block 705, the adjusting bolt 717 connected to the thin rope 703 pulls the pull rod 716 to make the connecting plate 714 drive the connecting rod 710 to rise on the guide frame 708, so that the oil plug 711 connected to the connecting rod 710 is pulled out from the discharge pipe 10, and the oil in the oil storage cylinder 9 flows into the discharge pipe 10 through the oil guide port 706 and finally enters. The oil pump 720 is put into the casing 1. At this time, the stopper 722 on the lifted connecting rod 710 will push open the blocking member 721 on the U-shaped frame 718 to the top of the blocking member 721. As the oil level in the oil storage cylinder 9 drops rapidly, the floating box 720 floating in the oil drops with the drop of the liquid level, so that the floating box 720 drives the U-shaped frame 718 connected to the inclined plate 719 to rotate, so that the blocking member 721 releases the limit on the stopper 722, so that the connecting rod 710 drives the oil plug 711 to drop, and the oil plug 711 will block the discharge pipe 10 again, and the oil in the oil storage cylinder 9 will no longer flow into the casing 1.

[0030] In a specific application scenario, the automatic oil replenishing module 7 is mainly suitable for the automatic oil replenishing link in the automatic oil replenishing process, that is, the automatic oil replenishing module 7 uses the floating box 720 and the oil plug 711 to enable the device to automatically cut off the continued supply of oil in the tank 1 by using the change of the liquid level after the transformer oil in the tank 1 is fully replenished, thereby realizing quantitative addition and avoiding excessive replenishment of the transformer oil in the tank 1.

[0031] Reference Figure 6 and Figure 7In a preferred embodiment, the outside of the pull rod 716 is connected to a fixing plate 801 by bolts, the fixing plate 801 is located above the connecting plate 714, the upper side of the fixing plate 801 is slidably connected to the bottom of the locking ring 802, the outside of the locking ring 802 is slidably connected to a guide buckle 803, the bottom of the guide buckle 803 is connected to the upper side of the fixing plate 801 by bolts, and a toothed ring 805 is arranged on the outside of the adjusting bolt 717; the toothed ring 805 is meshed with the rack 806, the side of the guide buckle 803 away from the toothed ring 805 is connected to a spring 804 by bolts, and one end of the spring 804 away from the guide buckle 803 is connected to the locking ring 802 The inner wall is connected by bolts; the bottom inner wall of the containing box 4 is connected with a vertical rod 807 by bolts, the outer sliding connection of the vertical rod 807 is connected with a float 808, the outer sliding connection of the vertical rod 807 is connected with a contact member 809, the bottom of the contact member 809 is connected with the outer part of the float 808 by bolts, and the outer part of the vertical rod 807 is provided with a thread groove 810, the outer part of the thread groove 810 is connected with a nut 811 through an external thread rotation; the outer sliding connection of the vertical rod 807 is connected with a limit switch 812, the limit switch 812 is located above the contact member 809, and the upper side of the limit switch 812 is connected with the bottom of the nut 811 by bolts.

[0032] Specifically, when it is necessary to control the single replenishment amount of the transformer in the box body 1 and the oil storage cylinder 9, the elastic force of the spring 804 is overcome to push the locking ring 802, and the locking ring 802 slides on the fixing plate 801 in the direction of the adjusting bolt 717, so that the rack 806 releases the lock on the gear ring 805, and the adjusting bolt 717 is rotated, and the adjusting bolt 717 is rotated a distance from the pull rod 716, so that the counterweight block 705 in the box body 1 drives the float 1 704 to descend a distance in the box body 1, and the locking ring 802 is released. Under the elastic force of the spring 804, the locking ring 802 is reset and the rack 806 locks the gear ring 805, and the adjusting bolt 717 no longer rotates. When the oil level in the oil storage cylinder 9 drops, the float 2 808 drives the contact member 809 to drop , so that the contact piece 809 and the limit switch 812 are no longer in contact, the oil pump 6 will start and slowly inject the oil in the oil pillow 3 into the oil storage cylinder 9 through the oil delivery conduit 5, turn the nut 811, the nut 811 moves up and down on the threaded groove 810, thereby adjusting the height of the limit switch 812 on the vertical rod 807, after the oil plug 711 blocks the discharge pipe 10 so that the oil storage cylinder 9 no longer injects oil into the tank body 1, as the oil delivery conduit 5 continues to inject oil into the oil storage cylinder 9, the oil level in the oil storage cylinder 9 gradually rises, thereby driving the float 808 to float up, and after the contact piece 809 contacts the limit switch 812, the limit switch 812 transmits a signal to the receiver on the oil pump 6, so that the oil pump 6 is turned off, and the oil delivery conduit 5 no longer injects oil into the oil storage cylinder 9.

[0033] In a specific application scenario, the oil quantity control module 8 is mainly suitable for the oil quantity control link in the oil quantity control process, that is, the oil quantity control module 8 uses the rack 806 and the gear ring 805 to allow the adjustment bolt 717 to remain stably in position after the adjustment is completed, thereby ensuring the stability of the final oil level in the box 1 when the oil is replenished in the box 1, and using the adjustable position limit switch 812 and the contact piece 809 to enable the device to control the oil amount in the oil storage cylinder 9, and then control the oil amount replenished into the box 1 at a single time, so that the device can quickly and conveniently control the amount of oil replenished.

[0034] Working principle: After the transformer oil in the box 1 is consumed to a certain extent, the oil level drops, and the float 704 connected to the counterweight 705 can no longer float, so that the counterweight 705 pulls the thin rope 703 to make the thin rope 703 tight. Under the gravity of the counterweight 705, the adjusting bolt 717 connected to the thin rope 703 pulls the pull rod 716 to make the connecting plate 714 drive the connecting rod 710 to rise on the guide frame 708, so that the oil plug 711 connected to the connecting rod 710 is pulled out from the discharge pipe 10, and the oil in the oil storage cylinder 9 flows into the discharge pipe 10 through the oil guide port 706 and finally enters the box 1. At this time, the oil on the raised connecting rod 710 The stopper 722 will push open the blocking member 721 on the U-shaped frame 718 to the top of the blocking member 721. As the oil level in the oil storage cylinder 9 drops rapidly, the floating box 720 floating in the oil drops as the liquid level drops, so that the floating box 720 drives the U-shaped frame 718 connected to the inclined plate 719 to rotate, so that the blocking member 721 releases the limit on the stopper 722, so that the connecting rod 710 drives the oil plug 711 to drop, and the oil plug 711 will block the discharge pipe 10 again, and the oil in the oil storage cylinder 9 will no longer flow into the box body 1. When it is necessary to control the single replenishment amount of the transformer in the box body 1 and the oil storage cylinder 9, the locking ring 802 is pushed to overcome the elastic force of the spring 804, and the lock The fixed ring 802 slides on the fixed plate 801 in the direction of the adjusting bolt 717, so that the rack 806 releases the lock on the gear ring 805, and the adjusting bolt 717 is turned to rotate the adjusting bolt 717 a certain distance from the pull rod 716, so that the counterweight block 705 in the box body 1 drives the float 1 704 to descend a certain distance in the box body 1, and the locking ring 802 is released. Under the elastic force of the spring 804, the locking ring 802 is reset and the rack 806 locks the gear ring 805, and the adjusting bolt 717 no longer rotates. When the oil level in the oil storage cylinder 9 drops, the float 2 808 drives the contact member 809 to drop, so that the contact member 809 is no longer in contact with the limit switch 812, and the oil pump 6 is Start and slowly inject the oil in the oil pillow 3 into the oil storage cylinder 9 through the oil delivery conduit 5, turn the nut 811, and the nut 811 moves up and down on the threaded groove 810, so as to adjust the height of the limit switch 812 on the vertical rod 807. After the oil plug 711 blocks the discharge pipe 10 so that the oil storage cylinder 9 no longer injects oil into the tank body 1, as the oil delivery conduit 5 continues to inject oil into the oil storage cylinder 9, the oil level in the oil storage cylinder 9 gradually rises, thereby driving the float 808 to float up. After the contact piece 809 contacts the limit switch 812, the limit switch 812 transmits a signal to the receiver on the oil pump 6, so that the oil pump 6 is turned off, and the oil delivery conduit 5 no longer injects oil into the oil storage cylinder 9.
