Description

TECHNICAL FIELD

[0001] The present application relates to the field of resistance-capacitance absorber, in particular to a commutation resistance-capacitance absorption device for a generator excitation system. BACKGROUND

[0002] The resistance-capacitance absorption device is used to absorb and consume the self-induced electromotive force generated by the inductive load when the circuit is disconnected, and can prevent the load insulation breakdown caused by overvoltage.

[0003] The resistance-capacitance absorber is often fixed by bolts and bases. This fixing method often needs to use multiple bolts for fixing. Since the bolts are prone to rust, they are not easy to disassemble, and tools need to be carried to unscrew the bolts, which is more troublesome. In addition, the base of the resistance-capacitance absorber is directly fixed by screwing the bolts during use, which is easy to cause loose installation and affect use. SUMMARY

[0004] Therefore, the present application aims to provide a commutation resistance-capacitance absorption device for a generator excitation system to solve the technical problems of inconvenient disassembly and loose installation.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a commutation resistance-capacitance absorption device for a generator excitation system, comprising a mounting plate, the top of the mounting plate is provided with a mounting bolt and an anti-dropping assembly on both sides, the anti-dropping assembly comprises a sliding groove, a sliding block and a mounting bracket, the top of the mounting plate is provided with a disassembly assembly, the disassembly assembly comprises a mounting slot, a mounting cavity, a limiting rod, a pressing rod, a fixing hook and a spring, the inside of the mounting slot is provided with a resistance-capacitance absorber body.

[0006] Further, the sliding block is located in the inside of the sliding groove, the mounting bracket is fixed on the top of the sliding block, the top of the mounting bracket penetrates a screw rod, and the bottom end of the screw rod is connected with a pressing plate.

[0007] By adopting the above technical scheme, after the mounting bolt is fixed, the worker rotates the screw rod, so that the pressing plate is pressed on the mounting bolt, and the mounting bolt is not easy to rotate and loosen.

[0008] Further, the disassembling component further comprises limiting grooves located on both sides of the resistor-capacitor absorber body, one end of the limiting rod extends to the inside of the limiting groove, a fixed block is fixed on the top of the limiting rod, a fixed rod is fixed on the bottom of the limiting rod, a movable groove is formed in the lower part of the inside of the mounting cavity, a movable block is fixed on the bottom of the fixed rod, a supporting rod is arranged on the upper part of the inside of the mounting cavity, the bottom end of the supporting rod is connected with the fixed hook, the spring is located on the top side of the fixed hook, a pressing rod is arranged on both sides of the top of the mounting groove, the bottom end of the pressing rod is connected with one end of the fixed hook, a first magnetic block is arranged on one side of the fixed rod, and a second magnetic block is arranged on one side of the inside of the mounting cavity.

[0009] By adopting the above technical scheme, when the resistor-capacitor absorber body is disassembled, the staff presses the pressing rod, one side makes the fixed hook and the fixed block separate, and under the repulsion between the first magnetic block and the second magnetic block, the limiting rod and the limiting groove can be separated.

[0010] Further, the top end of the screw rod is fixed with a knob, and the outer surface of the knob is provided with anti-skid lines.

[0011] By adopting the above technical scheme, the staff can make the screw rod rotate more conveniently through the knob, and the anti-skid lines can increase the friction of the knob.

[0012] Further, the bottom of the pressing plate is provided with a rubber pad, and the rubber pad is in contact with the top of the mounting bolt.

[0013] By adopting the above technical scheme, the rubber pad has a large friction, so that the mounting bolt is not easy to rotate and loosen.

[0014] Further, the sliding block and the sliding groove are matched, and the section view of the sliding block and the sliding groove is in the shape of "convex".

[0015] By adopting the above technical scheme, the "convex" design can make the sliding block and the sliding groove more stable when sliding.

[0016] Further, the first magnetic block and the second magnetic block are both permanent magnets, and the positive poles of the first magnetic block and the second magnetic block are opposite.

[0017] By adopting the above technical scheme, the positive poles of the first magnetic block and the second magnetic block are opposite, which can generate repulsion, so that the limiting rod can be reset.

[0018] Further, one end of the limiting rod is fixed with a first pressing plate, and the top end of the pressing rod is fixed with a second pressing plate.

[0019] By adopting the above technical scheme, the first pressing plate can facilitate pressing the limiting rod, and the second pressing plate can facilitate pressing the pressing rod.

[0020] Further, one side of the fixed block and one end of the fixed hook are arc-shaped designs.

[0021] By adopting the above technical scheme, the force can be guided when the fixed block and the fixed hook are extruded, so that the fixed hook moves upward.

[0022] To sum up, the present application mainly has the following beneficial effects:

[0023] 1. The present application is provided with a disassembly component. When the blocking capacitor absorber body is disassembled, the staff tests the pressure on the pressing rod, so that one end of the fixed hook moves upward and extrudes the spring, so that the fixed hook and the fixed block are separated. At the same time, under the repulsive force of the first magnetic block and the second magnetic block, the limiting rod moves away from the blocking capacitor absorber body, so that the limiting rod and the limiting groove are separated. Thus, the staff can take out the blocking capacitor absorber body from the installation slot. When the blocking capacitor absorber is installed, the staff first inserts the blocking capacitor absorber into the installation slot, and then the staff tests the pressure on the limiting rod, so that the limiting rod overcomes the repulsive force of the first magnetic block and the second magnetic block and is inserted into the limiting groove. At the same time, the fixed block extrudes the fixed hook. Since one side of the fixed block and one end of the fixed hook are arc-shaped, when the fixed block and the fixed hook are extruded, the fixed hook moves upward. When the fixed block moves to a certain position, the fixed hook is buckled on the fixed block, so that the limiting rod can be fixed, thereby achieving the purpose of installing the blocking capacitor absorber. The installation and disassembly are more rapid, time-saving, and increase the efficiency of installation and disassembly of the blocking capacitor absorber body.

[0024] 2. The present application is provided with an anti-disassembly component. When the blocking capacitor absorption device is installed, the staff first fixes the installation bolt, and then slides the mounting bracket, so that the sliding block slides in the sliding groove, and then the installation bolt is located inside the mounting bracket. Then the staff rotates the screw rod, so that the pressing plate moves downward, and then the rubber pad is on the top end of the installation bolt. By pressing and fixing the installation bolt, the influence of the vibration of the working environment on the installation bolt is avoided, and the stability of the installed blocking capacitor absorption device is improved.

[0034] Referring to Figure 1 and Figure 5 , the top end of the screw rod 304 is fixed with the knob 306, the outer surface of the knob 306 is provided with anti-skid lines, the staff makes the screw rod 304 rotate more conveniently through the knob 306, the anti-skid lines can increase the friction of the knob 306, the bottom of the pressing plate 305 is provided with the rubber pad 307, and the rubber pad 307 is in contact with the top of the mounting bolt 2, the rubber pad 307 has great friction, in turn, the mounting bolt 2 is not easy to rotate and loosen.

[0035] Referring to Figure 2The slider 302 is matched with the sliding groove 301, and the profile of the slider 302 and the sliding groove 301 is in the shape of a "convex" character. The "convex" character design can make the slider 302 and the sliding groove 301 more stable when sliding.

[0036] Referring to Figure 1 and Figure 3 The first magnetic block 408 and the second magnetic block 409 are both permanent magnets, and the positive poles of the first magnetic block 408 and the second magnetic block 409 are opposite. The opposite positive poles of the first magnetic block 408 and the second magnetic block 409 generate repulsion, so that the limiting rod 403 can be reset. One side of the fixed block 414 and one end of the fixed hook 413 are both arc-shaped designs, which can guide the force when the fixed block 414 and the fixed hook 413 are pressed, so that the fixed hook 413 moves upward.

[0037] The implementation principle of the embodiment is as follows: first, when the worker installs the resistance-capacitance absorption device, the worker first fixes the installation bolt 2, then the worker slides the mounting bracket 303, so that the slider 302 slides in the sliding groove 301, and then the installation bolt 2 is located inside the mounting bracket 303. Then the worker rotates the screw rod 304, so that the pressing plate 305 moves downward, and then the rubber pad 307 is on the top of the installation bolt 2. By tightly fixing the installation bolt 2, the influence of the vibration of the working environment on the installation bolt 2 is avoided. When the worker disassembles the resistance-capacitance absorber main body 5, the worker tests the pressing rod 415, so that one end of the fixed hook 413 moves upward and presses the spring 412, and then the fixed hook 413 is separated from the fixed block 414. At the same time, under the repulsion of the first magnetic block 408 and the second magnetic block 409, the limiting rod 403 moves away from the resistance-capacitance absorber main body 5, so that the limiting rod 403 is separated from the limiting groove 410. In this way, the worker can take out the resistance-capacitance absorber main body 5 from the mounting slot 401. When the worker installs the resistance-capacitance absorber, the worker first inserts the resistance-capacitance absorber main body 5 into the mounting slot 401, and then the worker tests the limiting rod 403, so that the limiting rod 403 overcomes the repulsion of the first magnetic block 408 and the second magnetic block 409 and is inserted into the limiting groove 410. At the same time, the fixed block 414 will press the fixed hook 413. Since one side of the fixed block 414 and one end of the fixed hook 413 are both arc-shaped, when the fixed block 414 and the fixed hook 413 are pressed, the fixed hook 413 will move upward. When the fixed block 414 moves to a certain position, the fixed hook 413 will be buckled on the fixed block 414, so as to fix the limiting rod 403, thereby achieving the purpose of installing the resistance-capacitance absorber. The installation and disassembly are more rapid.
