[0028] In the embodiment, the inclined clamping block 3111 movably penetrates the fixed seat 311, and the inclined clamping block 3111 is connected with the clamping groove 318, one end of the second spring 3113 is fixedly connected with the movable block 3110, the outer end of the connecting rod 3112 is movably connected with the fixed seat 311, through the cooperation of the fixed seat 311, the mounting seat 312, the clamping groove 318, the movable slot 319, the movable block 3110, the inclined clamping block 3111, the connecting rod 3112 and the second spring 3113, the mutual inductor body 313 can be conveniently disassembled by manual, so that the mutual inductor body 313 can be conveniently taken out from the box body 1 by manual, and then the mutual inductor body 313 can be conveniently repaired and maintained by manual, and the device is convenient for subsequent use.

[0029] Furthermore, the top of the first spring 317 is fixedly connected to the bottom of the mounting plate 6, and the first spring 317 is sleeved on the outside of the connecting post 314. Through the cooperation of the connecting post 314, the top ring 315, the bottom ring 316, and the first spring 317, when the inclined plate block 3111 separates from the slot 318, it can press upward against the mounting base 312, thereby allowing the slot 318 and the inclined plate block 3111 to quickly misalign, freeing up the operator's hands and making it easier for the operator to disassemble the transformer body 313, thus increasing the applicability of the device.

[0030] When it is necessary to disassemble the transformer body 313, firstly, manually open the cover 2, then manually hold the pull rod and pull the connecting rod 3112 outward. This causes the movable block 3110, which is fixedly connected to the inner end of the connecting rod 3112, to move the inclined locking block 3111 outward in sync, allowing the inclined locking block 3111 to separate from the slot 318. Then, under the elastic force of the first spring 317, the connecting column 314 drives the top ring 315 to press upward against the bottom of the mounting base 312, thereby causing the slot 318 on the side wall of the mounting base 312 to misalign with the inclined locking block 3111. Without needing to continuously support the pull rod, the transformer body 313 can then be removed upward. When installing the main body 313 and the mounting base 312, simply place the mounting base 312 into the fixed base 311 manually and press it down. Due to the upper slope of the inclined block 3111, when the mounting base 312 moves down and presses against the inclined block 3111, the inclined block 3111 can be pressed into the movable groove 319. Then, when the mounting base 312 is fully inserted into the fixed base 311, the second spring 3113, under the action of elasticity, can cause the movable block 3110 to drive the inclined block 3111 to engage with the groove 318, thereby fixing the mounting base 312 in the fixed base 311. The installation operation is completed, and the operation is simple and convenient, increasing the applicability of the device.

[0031] Example 2: Based on Example 1, a preferred embodiment of the current transformer for high-power power systems provided by the present invention is as follows: Figures 1-7 As shown: The limiting mechanism 32 includes a fixed column 321 fixedly connected to the upper part of the support plate 5. A top block 322 is fixedly connected to the top of the fixed column 321. A third spring 323 is fixedly connected to the bottom of the top block 322. A limiting ring 324 is fixedly connected to the bottom outer wall of the fixed column 321. A fixed rod 325 is fixedly connected to the upper part of the support plate 5. A rotating rod 326 is rotatably connected to the top of the fixed rod 325 through a bearing. A limiting rod 327 is movably connected to the end of the rotating rod 326. A handle 328 is fixedly connected to the top of the limiting rod 327. A fourth spring 329 is fixedly connected to the bottom of the handle 328.

[0033] Further, the limiting rod 327 is connected with the limiting groove 3210, the bottom end of the fourth spring 329 is fixedly connected with the upper portion of the rotating rod 326, and the bottom portion of the rotating rod 326 is abutted with the upper portion of the mounting plate 6.

[0034] When the transformer body 313 needs to be disassembled, the limiting rod 327 is separated from the limiting groove 3210 by manually holding the handle 328 and pulling the limiting rod 327 upward, and then the rotating rod 326 is rotated to an angle that can pass through the through hole. Then, under the action of the third spring 323, the mounting plate 6 can be slid upward through the fixed column 321, so that the transformer body 313 can be lifted upward, thereby facilitating manual disassembly and assembly of the transformer body 313. When the installation is completed, the bottom portion of the mounting plate 6 is limited by the limiting ring 324, and when the mounting plate 6 moves downward, the rotating rod 326 can pass through the through hole. Then, the rotating rod 326 is rotated by manual operation, and the limiting rod 327 is connected with the limiting groove 3210. Under the action of the fourth spring 329, the limiting rod 327 is connected with the limiting groove 3210, thereby limiting the rotating rod 326, and the mounting plate 6 is fixed, so that the transformer body 313 can be stored in the box body 1 for subsequent use.

[0036] In the embodiment, the top end of the supporting rod 335 is movably connected with the connecting block 336 through a pin, one end of the fifth spring 334 is fixedly connected with the sliding block 333, and the sliding slot 331, the sliding rod 332, the sliding block 333, the fifth spring 334, the supporting rod 335, the connecting block 336 and the damper 337 are matched, so that when the box body 1 is vibrated by external force, the damping effect can be achieved, the mutual inductor body 313 can be protected, the service life of the device is prolonged, and the applicability of the device is further improved.

[0037] Further, the bottom end of the damper 337 is fixedly installed on the bottom of the inner wall of the box body 1.

[0038] When the box body 1 is vibrated by external force, the supporting plate 5 and the box body 1 can be relatively moved under the action of gravity, and since the supporting rod 335 is movably connected between the connecting block 336 and the sliding block 333 through a pin, when the supporting plate 5 and the box body 1 are relatively moved, the sliding block 333 can relatively slide in the sliding slot 331 through the sliding rod 332, the fifth spring 334 can be deformed, and since the damper 337 is fixedly installed between the supporting plate 5 and the box body 1, the damping effect can be achieved under the cooperation of the fifth spring 334 and the damper 337, the mutual inductor body 313 can be protected, and the applicability of the device is further improved.
