Description
COMMUTATION RESISTANCE-CAPACITANCE ABSORPTION DEVICE FOR
GENERATOR EXCITATION SYSTEM
[0001] The present application relates to the technical field of resistance-capacitance absorbers, and in particular to a commutation resistance-capacitance absorption device for a generator excitation system.
[0002] A resistance-capacitance absorption device is used to absorb and consume the self-induced electromotive force generated by an inductive load when a circuit is disconnected, which can prevent the insulation breakdown of load caused by overvoltage.
[0003] The resistance-capacitance absorber is generally fixed with the base by bolts. This fixing method generally requires multiple bolts for fixing. However, the bolts are easy to rust and difficult to disassemble, and the bolts can only be unscrewed with tools, so that this fixing method is inconvenient. Besides, the base of the resistance-capacitance absorber is directly screwed and fixed by bolts while in use, which is easy to cause the installation of the base to loose, where the bolts are easy to loosen and affect the use.
[0004] Based on the above, an object of the present application is to provide a commutation resistance-capacitance absorption device for a generator excitation system, so as to solve the technical problems of inconvenient disassembly and unstable installation.
[0005] In order to achieve the above objects, the following technical solutions are provided according to the present application. A commutation resistance-capacitance absorption device for a generator excitation system, includes a mounting plate. Two sides of the top of the mounting plate are each provided with a mounting bolt and an anti-loosening component. The anti-loosening component includes a sliding groove, a sliding block and a mounting frame. A dismounting component is arranged at the top of the mounting plate. The dismounting component includes a mounting groove, a mounting cavity, a position-limiting rod, a press -1-
rod, a fixing hook and a spring. À resistance-capacitance absorber main body is arranged in the mounting groove.
[0006] Further, the sliding block is located in the sliding groove, the mounting frame is fixed at the top of the sliding block, and a screw rod penetrates through the top of the mounting frame. The bottom of the screw rod is connected with a pressure plate.
[0007] By adopting the above technical solution, after the mounting bolt is fixed, the operator rotates the screw rod, so that the pressure plate is pressed on the mounting bolt, and the mounting bolt is thereby not easy to loosen due to rotation by itself.
[0008] Further, the dismounting component further includes a position-limiting groove located at two sides of the resistance-capacitance absorber main body. One end of the position-limiting rod extends into the position-limiting groove. A fixing block is fixed at the top of the position-limiting rod. A fixing rod is fixed at the bottom of the position-limiting rod.
A movement groove is arranged at an inner lower part of the mounting cavity. A movable block is fixed at the bottom of the fixing rod. A support rod is arranged at an inner upper part of the mounting cavity. The bottom end of the support rod is connected with the fixing hook.
The spring is located on one side of the top of the fixing hook. The press rod penetrates through two sides of the top of the mounting groove. The bottom end of the press rod is connected with one end of the fixing hook. A first magnetic block is mounted on one side of the fixing rod, and a second magnetic block is arranged on an inner side of the mounting cavity.
[0009] By adopting the above technical solution, when dismounting the resistance-capacitance absorber main body, the operator exerts pressure on the press rod to separate the fixing hook from the fixing block, and then the position-limiting rod is separated from the position-limiting groove under the repulsive force between the first magnetic block and the second magnetic block.
[0010] Further, a knob is fixed at the top end of the screw rod, and an outer surface of the knob 1s provided with anti-slip lines.
[0011] By adopting the above technical solution, the operator can easily rotate the screw rod with the knob, and the anti-slip lines can increase the friction force of the knob.
[0012] Further, a rubber pad is arranged at the bottom of the pressure plate, and the rubber -2-
pad is in contact with the top of the mounting bolt.
[0013] By adopting the above technical solution, the rubber pad has large friction force, so that the mounting bolt 1s not easy to loosen due to rotation by itself.
[0014] Further, the sliding block fits the sliding groove, and the cross section of the sliding block and the sliding groove is in a " "5" shape.
[0015] By adopting the above technical solution, the " +"-shaped design can make the sliding block and the sliding groove more stable during sliding.
[0016] Further, the first magnetic block and the second magnetic block are both permanent magnets, and a pair of same-polarity poles of the first magnetic block and the second magnetic block, face each other.
[0017] By adopting the above technical solution, the face-to-face same-polarity poles of the first magnetic block and the second magnetic block, generates a repulsive force which can force the position-limiting rod to reset.
[0018] Further, a first press plate is fixed at one end of the position-limiting rod, and a second press plate is fixed at the top end of the press rod.
[0019] By adopting the above technical solution, the pressure can be easily applied on the position-limiting rod with the first press plate, and the pressure can be easily applied on the press rod with the second press plate.
[0020] Further, one side of the fixing block and one end of the fixing hook are arc-shaped.
[0021] By adopting the above technical solution, the force can be guided when the fixing block squeezes the fixing hook, so that the fixing hook moves upward.
[0022] In summary, the present application mainly has the following beneficial effects.
[0023] 1. A dismounting component is provided according to the present application. When dismounting the resistance-capacitance absorber main body, the operator presses the press rod, so that one end of the fixing hook moves upwards and squeezes the spring, and then the fixing hook is separated from the fixing block; at the same time, under the repulsive force of the first magnetic block and the second magnetic block, the position-limiting rod moves away from the resistance-capacitance absorber main body, and the position-limiting rod escapes from the position-limiting groove, so that the operator can take out the resistance-capacitance absorber -3-
main body from the mounting groove. When mounting the resistance-capacitance absorber, the operator first inserts the resistance-capacitance absorber into the mounting groove, and then the operator presses the position-limiting rod, so that the position-limiting rod is inserted into the position-limiting groove against the repulsive force of the first magnetic block and the second magnetic block; and at the same time, the fixing block squeezes the fixing hook; because one side of the fixing block and one end of the fixing hook are both arc-shaped, the fixing hook moves upward when the fixing block squeezes the fixing hook; when the fixing block moves to a certain position, the fixing hook hooks on the fixing block to fix the position-limiting rod, achieving installation of the resistance-capacitance absorber. The mounting and dismounting of the resistance-capacitance absorber are faster, which saves time and improves the mounting and dismounting efficiency of the resistance-capacitance absorber main body.
[0024] 2. An anti-loosening component is provided according to the present application.
When mounting the resistance-capacitance absorption device, the operator fixes the mounting bolt firstly, and then slides the mounting frame, so that the sliding block slides in the sliding groove until the mounting bolt is positioned on the inner side of the mounting frame; then the operator rotates the screw rod to force the pressure plate to move downwards, so that the rubber pad squeezes the top end of the mounting bolt. The mounting bolt is further fixed by pressing, so that the mounting bolt is prevented from loosening due to the vibration of the working environment, improving the stability after the resistance-capacitance absorption device is mounted.

[0031] Technical solutions in the embodiments of the present application are clearly and completely described hereinafter in conjunction with the drawings in the embodiments of the present application. The embodiments described below with reference to the drawings are only exemplary embodiments which are only used to explain the present application, and should not be construed as limiting the present application.
[0032] The embodiment of the present application is described below according to the overall structure of the present application.
[0033] As shown in FIG. 1 to FIG. 5, a commutation resistance-capacitance absorption device for a generator excitation system, includes a mounting plate 1. Two sides of the top of the mounting plate 1 are each provided with a mounting bolt 2 and an anti-loosening component 3. The anti-loosening component 3 includes a sliding groove 301, a sliding block 302 and a mounting frame 303. The sliding block 302 is located in the sliding groove 301, the mounting frame 303 is fixed at the top of the sliding block 302, and a screw rod 304 penetrates through the top of the mounting frame 303. The bottom of the screw rod 304 is connected with a pressure plate 305. After the mounting bolt 2 is fixed, the operator rotates the screw rod 304, so that the pressure plate 305 is pressed on the mounting bolt 2, and the mounting bolt 2 is thereby not easy to loosen due to rotation by itself. A dismounting component 4 is arranged at the top of the mounting plate 1. The dismounting component 4 -5.
includes a mounting groove 401, a mounting cavity 402, a position-limiting rod 403, a press rod 415, a fixing hook 413 and a spring 412. The dismounting component 4 further includes a position-limiting groove 410 located at two sides of a resistance-capacitance absorber main body 5. One end of the position-limiting rod 403 extends into the position-limiting groove 410. A fixing block 414 is fixed at the top of the position-limiting rod 403. A fixing rod 404 is fixed at the bottom of the position-limiting rod 403. A movement groove 405 is arranged at an inner lower part of the mounting cavity 402. A movable block 406 is fixed at the bottom of the fixing rod 404. A support rod 411 is arranged at an inner upper part of the mounting cavity 402. The bottom end of the support rod 411 is connected with the fixing hook 413. The spring 412 is located on one side of the top of the fixing hook 413. The press rod 415 penetrates through two sides of the top of the mounting groove 401. The bottom end of the press rod 415 is connected with one end of the fixing hook 413. A first magnetic block 408 is mounted on one side of the fixing rod 404, and a second magnetic block 409 is arranged on an inner side of the mounting cavity 402. When dismounting the resistance-capacitance absorber main body 5, the operator exerts pressure on the press rod 415 to separate the fixing hook 413 from the fixing block 414, and then the position-limiting rod 403 is separated from the position-limiting groove 410 under the repulsive force between the first magnetic block 408 and the second magnetic block 409. The resistance-capacitance absorber main body 5 is arranged in the mounting groove 401. The first magnetic block 408 and the second magnetic block 409 are both permanent magnets, and a pair of same-polarity poles of the first magnetic block 408 and the second magnetic block 409, face each other. The face-to-face same-polarity poles of the first magnetic block 408 and the second magnetic block 409, generates a repulsive force which can force the position-limiting rod 403 to reset.
[0034] Referring to FIG. 1 and FIG. 5, a knob 306 is fixed at the top end of the screw rod 304, and an outer surface of the knob 306 is provided with anti-slip lines. The operator can easily rotate the screw rod 304 with the knob 306, and the anti-slip lines can increase the friction force of the knob 306. A rubber pad 307 is arranged at the bottom of the pressure plate 305, and the rubber pad 307 is in contact with the top of the mounting bolt 2. The rubber pad 307 has large friction force, so that the mounting bolt 2 is not easy to loosen due to rotation by itself.
[0035] Referring to FIG. 2, the sliding block 302 fits the sliding groove 301, and the cross -6-
section of the sliding block 302 and the sliding groove 301 is in a "r""" shape. The "y" "-shaped design can make the sliding block 302 and the sliding groove 301 more stable during sliding.
[0036] Referring to FIG. 1 and FIG. 3, the first magnetic block 408 and the second magnetic block 409 are both permanent magnets, and a pair of same-polarity poles of the first magnetic block 408 and the second magnetic block 409, face each other. The face-to-face same-polarity poles of the first magnetic block 408 and the second magnetic block 409, generates a repulsive force which can force the position-limiting rod 403 to reset. One side of the fixing block 414 and one end of the fixing hook 413 are arc-shaped. The force can be guided when the fixing block 414 squeezes the fixing hook 413, so that the fixing hook 413 moves upward.
[0037] The implementation principle of this embodiment is as follows. Firstly, when an operator mounts the resistance-capacitance absorption device, the operator fixes the mounting bolt 2 firstly, and then slides the mounting frame 303, so that the sliding block 302 slides in the sliding groove 301 until the mounting bolt 2 is positioned on the inner side of the mounting frame 303; then the operator rotates the screw rod 304 to force the pressure plate 305 to move downwards, so that the rubber pad 307 squeezes the top end of the mounting bolt 2. The mounting bolt 2 is further fixed by pressing, so that the mounting bolt 2 is prevented from loosening due to the vibration of the working environment. When dismounting the resistance-capacitance absorber main body 5, the operator presses the press rod 415, so that one end of the fixing hook 413 moves upwards and squeezes the spring 412, and then the fixing hook 413 is separated from the fixing block 414; at the same time, under the repulsive force of the first magnetic block 408 and the second magnetic block 409, the position-limiting rod 403 moves away from the resistance-capacitance absorber main body 5, and the position-limiting rod 403 escapes from the position-limiting groove 410, so that the operator can take out the resistance-capacitance absorber main body 5 from the mounting groove 401.
When mounting the resistance-capacitance absorber, the operator first inserts the resistance-capacitance absorber main body 5 into the mounting groove 401, and then the operator presses the position-limiting rod 403, so that the position-limiting rod 403 is inserted into the position-limiting groove 410 against the repulsive force of the first magnetic block 408 and the second magnetic block 409; and at the same time, the fixing block 414 squeezes the fixing hook 413; because one side of the fixing block 414 and one end of the fixing hook -7-
413 are both arc-shaped, the fixing hook 413 moves upward when the fixing block 414 squeezes the fixing hook 413; when the fixing block 414 moves to a certain position, the fixing hook 413 hooks on the fixing block 414 to fix the position-limiting rod 403, achieving installation of the resistance-capacitance absorber. The mounting and dismounting of the resistance-capacitance absorber are faster.
[0038] Although the embodiment of the present application has been shown and described, this specific embodiment is only used for explaining the present application and is not intended to limit the present application. Specific features, structures, materials or characteristics described herein may be combined in any one or more embodiments or examples in a suitable manner. After reading this specification, those skilled in the art can make, as needed, changes, substitutions and modifications to the embodiments with no inventive contributions, without departing from the principle and object of the present application. As long as those modifications, substitutions and variations fall within the scope of the appended claims of the present application, they shall be protected by the patent law. -8-
