Description

Technical Field

[0001] The utility model relates to the technical field of excitation regulators, and more specifically, to an excitation regulator for hydropower development. Background Art

[0002] The excitation regulator is an important device in the power system, mainly used to fine-tune the grid voltage and keep it stable. Its working principle is to adjust the output voltage and reactive power of the generator by changing the size and direction of the excitation current to meet the needs of the power system.

[0003] Excitation regulators are often used in hydropower development. During the use of excitation regulators, operators need to frequently inspect and maintain the excitation regulators to ensure the normal operation of the excitation regulators, thereby ensuring the stability of the grid voltage. Existing excitation regulators are generally fixed and installed with bolts. During the disassembly process, operators need to use corresponding tools to disassemble the excitation regulators, which is very troublesome and affects the maintenance efficiency of the excitation regulators. Therefore, they need to be improved. Utility Model Content

The front and back sides of the installation boxes 4 are movably installed with limit blocks 5, and a card block 6 located inside the installation box 4 is fixedly connected between the limit blocks 5. The right end of the card block 6 is movably connected to the inner wall of the regulator body 2, and a first spring 7 is fixedly installed on the left side of the card block 6. The left end of the first spring 7 is fixedly connected to the inner surface of the installation box 4, and the first spring 7 can push the card block 6 to move under the action of elastic recovery;

[0036] There are two support rods 8, which are respectively fixedly mounted on the left and right sides of the regulator body 2.

[0037] The operator presses the pressing plate 9 so that the pressing plate 9 drives the fixing block 10 to move inward, and then the fixing block 10 can push the clamping block 6 to move inward, so that the clamping block 6 can be disengaged from the engagement with the regulator body 2, and the fixing effect on the cover plate 3 can be released. At this time, the operator can remove the cover plate 3 by moving the cover plate 3 upward, which facilitates the operator to inspect and repair the electronic components inside the regulator body 2.

[0038] Among them, the rebound mechanism includes:

[0039] There are two fixed boxes 11, which are fixedly mounted on the tops of the left and right sides of the inner surface of the regulator body 2, respectively. A movable plate 13 is movably mounted on the top of the fixed box 11, and the top of the movable plate 13 is movably connected to the bottom of the cover plate 3;

[0040] The second spring 12 has a top end fixedly connected to the bottom of the movable plate 13 , and a bottom end of the second spring 12 fixedly connected to the bottom of the inner surface of the fixed box 11 .

[0041] The second spring 12 is in a compressed state, so that after the cover plate 3 is released, the second spring 12 can push the movable plate 13 to move upward, so that the movable plate 13 lifts up the cover plate 3 .

[0042] Heat dissipation holes 14 are provided inside the left and right sides of the regulator body 2 , and mounting blocks 15 are fixedly installed on the left and right sides of the regulator body 2 .

[0043] By providing the heat dissipation holes 14 , the electronic components inside the regulator body 2 can dissipate heat through the heat dissipation holes 14 .

[0044] A vertical rod 16 is fixedly installed between the installation blocks 15 , and a sliding block 17 is movably sleeved on the outer surface of the vertical rod 16 .

[0045] The outer surface of the vertical rod 16 is smooth, so that the slider 17 can move up and down more smoothly.

[0046] The bottom of the sliding block 17 is fixedly connected with a return spring 18 , and the bottom end of the return spring 18 is fixedly connected to the upper surface of the mounting block 15 .

[0047] When the slider 17 moves downward, the return spring 18 will be compressed, so that the return spring 18 can push the slider 17 upward under the action of elastic recovery.

[0048] A baffle 19 is fixedly connected between the sliders 17 , a through hole 20 is provided inside the baffle 19 , a connecting block 21 is fixedly connected to the bottom of the baffle 19 , and a notch 22 is provided inside the connecting block 21 .

[0049] When the through hole 20 overlaps with the heat dissipation hole 14 , the electronic components inside the regulator body 2 can dissipate heat through the heat dissipation hole 14 and the through hole 20 .

[0052] The working principle and use process of this utility model:

[0053] When the operator needs to inspect the control panel 1 as a whole, he can push the pressing plate 9 inward so that the pressing plate 9 drives the fixing block 10 to move inward, thereby causing the fixing block 10 to push the clamping block 6 to move inward, thereby releasing the clamping block 6 from the regulator body 2, thereby releasing the fixing effect on the cover plate 3. At this time, the second spring 12 will push the movable plate 13 upward under the action of elastic recovery, thereby causing the movable plate 13 to lift the cover plate 3, making it convenient for the operator to remove the cover plate 3, thereby facilitating the operator to inspect the electronic components inside the regulator body 2.

[0054] When the control panel 1 as a whole is not in use, the baffle 19 can be pressed downward to stagger the through hole 20 and the heat dissipation hole 14, so that the baffle 19 can close the heat dissipation hole 14, thereby preventing external dust from entering the interior of the regulator body 2 through the heat dissipation hole 14, and preventing dust from accumulating on the surface of the electronic components inside the regulator body 2. When the baffle 19 moves downward to insert the connecting block 21 into the interior of the fixing plate 23, the plug rod 24 can be pressed inward to insert the plug rod 24 into the interior of the slot 22, so that the connecting block 21 can be fixed, and then the baffle 19 can be fixed, so that the baffle 19 keeps the heat dissipation hole 14 closed.
