Description
Technical Field
[0001] The utility model relates to the technical field of instrument transformer installation, in particular to an auxiliary device for installing and removing instrument transformers. Background Technique
[0002] The instrument transformer, also known as the measuring transformer, is a general term for current transformers and voltage transformers. It can transform high voltage into low voltage and large current into small current for measurement or protection systems. Currently, instrument transformers are usually installed on the mounting rack through bolts and nuts. When disassembling and assembling the instrument transformer, the staff needs to use a wrench to hold the bolt head of the bolt, and then use an electric wrench to rotate the nut with the other hand. This process needs to be repeated many times.
[0003] After retrieval, the patent with the Chinese patent publication number CN219075549U discloses an auxiliary device for installing and removing instrument transformers, including a hollow plate and an adjusting unit; Hollow plate: The dovetail chutes longitudinally symmetrically arranged on its bottom wall surface are both slidably connected with L-shaped moving plates, and bolt placement seats are placed in the grooves arranged at the outer ends of the upper surfaces of the L-shaped moving plates; Adjusting unit: It includes a gear and a tooth groove. The middle of the top wall surface of the hollow plate is rotationally connected with a gear through a rotating shaft. The relative inner sides of the two L-shaped moving plates are both provided with horizontally uniformly distributed tooth grooves. The tooth grooves located on the same L-shaped moving plate are all meshed with the gear, meeting the needs of installing and removing instrument transformers of different models, being convenient and fast. One person can also quickly complete the installation and removal operation of the instrument transformer, greatly improving the work efficiency of the staff.

By cooperating with the rotating part 3 on the mounting rod 2 through the adjusting component 6, the two mounting components 4 can be synchronously adjusted.
[0033] A rectangular groove 5 is opened on one side outer wall of the adjusting seat 1. The adjusting component 6 is installed on the inner wall of the rectangular groove 5. The mounting component 4 includes a mounting frame 17. One end of the mounting frame 17 is fixedly connected with an adjusting frame 11 slidably connected to the inner wall of the rectangular groove 5. Rectangular openings 12 are opened on both outer walls of the mounting frame 17, and the same mounting seat 13 is slidably connected to the inner walls of the two rectangular openings 12. The top outer wall of the mounting seat 13 is rotatably connected with an adjusting part 14.

[0040] The adjusting component 6 in the rectangular groove 5 is protected by the cover plate to prevent the exposed adjusting component 6 from being damaged. At the same time, the detachable cover plate facilitates regular maintenance of the structure in the adjusting component 6.
[0041] Working principle: During use, first adjust according to the positions of the two bolts on the mutual inductor. When adjusting, rotate the rotating part 3. The rotating part 3 drives the worm to rotate. The worm drives the worm wheel 9 to drive the two screws 10 to rotate. When the screws 10 rotate, they directly drive the mounting frame 17 to move through the adjusting frame 11. When the mounting frame 17 moves, it is convenient to drive the mounting seat 13 to move. When the position is adjusted, then place the bolt into the rib groove 18, and drive the rotating seat 15 to drive the screw 10 to rotate by rotating the adjusting part 14, so as to facilitate the installation of the bolt on the mutual inductor. When encountering a special installation position, the position of the mounting seat 13 on the mounting frame 17 can be adjusted separately. When the position of the sliding seat 13 is adjusted, lock the mounting seat 13 on the mounting frame 17 through the two locking bolts 16.
