Description

Technical Field

[0001] This invention relates to the field of regulating device technology, and in particular to an adaptive reactance regulating device for a converter voltage regulator. Background Technology

[0002] Converter voltage regulators (also known as controlled rectifiers) and adaptive reactance regulators play a crucial role in power electronics technology and power systems, especially given the increasing demands for power quality and stability. A converter voltage regulator is a device used to regulate voltage and current, commonly found in substations and power transmission systems. It achieves smooth voltage regulation by controlling switching elements (such as thyristors or MOSFETs) in the rectifier.

[0003] Existing converter voltage regulator adjustment devices require switching gears and then changing the reactance adjustment ratio by rotating the adjustment knob. After the ratio is adjusted, the internal adaptive adjustment device makes the reactance value adaptively adjusted within the set fluctuation range. However, when rotating the adjustment knob, the operator cannot feel the adjustment ratio and needs to rely entirely on visual observation of the rotation direction and adjustment ratio of the adjustment knob. When the operator is negligent, it is easy to cause the adjustment ratio to be wrong, resulting in errors in subsequent reactance adjustment. Summary of the Invention

The insert rods are slidably inserted between the inner walls of the insertion holes. A rack is fixedly installed on the lower surface of the arc plate, and the rack meshes with the gear.

[0015] As a further embodiment of the present invention, a T-shaped groove is formed on the outer circumferential surface of the swivel cap, a push block is slidably installed between the inner walls of the T-shaped groove, a guide post is fixedly installed on the outer surface of the push block near the arc plate, a through groove is formed on the inner wall of the T-shaped groove, a second guide groove is formed on the outer circumferential surface of the arc plate, and the guide post is slidably installed through the through groove and the inner wall of the second guide groove.

[0021] When the semicircular ring can move along its diameter, it can drive the friction block to move along the diameter of the semicircular ring. The semicircular ring drives the friction block to move closer to or away from the friction ring, which increases or decreases the force of the friction block against the friction ring, thereby changing the magnitude of the friction force during movement. This allows the operator to know that the frictional resistance generated at different gear positions is different, enabling the operator to pay attention to the adjustment range and proportion, avoid operator errors, and ensure that subsequent reactance adjustment does not have errors.

[0044] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0045] To allow the operator to feel the range of motion when turning the adjustment knob, such as... Figure 1 and Figure 2 As shown, this invention provides an adaptive reactance adjustment device for a converter voltage regulator, comprising: a nut 100, a rotating rod 200, a fixed ring 300, a friction block 500, and a semi-circular ring 600. Specifically, as shown... Figure 3 As shown, the rotating cap 100 has a receiving cavity inside, and the rotating rod 200 is disposed inside the receiving cavity. The rotating cap 100 is sleeved on the outer surface of the rotating rod 200 and can rotate about the central axis of the rotating rod 200. The rotation direction of the rotating cap 100 is as follows: Figure 3 As indicated by the arrow at the top, the rotating rod 200 is configured to rotate simultaneously with the rotating cap 100. Operation involves rotating the rotating rod 200 via the rotating cap 100, thereby adjusting the adjustment coefficient of the adaptive reactance adjustment device inside the converter voltage regulator. This is done to allow the operator to perceive changes in the adjustment coefficient range and to identify the selected setting. Figure 4As shown, the fixing ring 300 is disposed within the receiving cavity of the rotating cap 100 and fixed to the outer surface of the adaptive reactance regulating device for the converter voltage regulator. The fixing ring 300 is sleeved on the outer surface of the rotating rod 200. A friction ring 400 is fixedly connected to the upper surface of the fixing ring 300. One end of a friction block 500 abuts against the outer circumferential surface of the friction ring 400. The friction block 500 can be made of rubber, thus generating friction between the abutting surfaces after abutting against the friction ring 400. The friction block 500 is configured to move along the outer circumferential surface of the friction ring 400 when the rotating cap 100 rotates. This movement generates resistance through friction, allowing the operator to clearly feel whether the rotating cap 100 is rotating. A semicircular ring 600 is disposed within the receiving cavity of the rotary cap 100. The semicircular ring 600 is configured to move along its diameter. The friction block 500 is coupled to the semicircular ring 600. When the semicircular ring 600 can move along its diameter, it can drive the friction block 500 to move along the diameter of the semicircular ring 600. By moving the friction block 500 closer to or away from the friction ring 400 through the semicircular ring 600, the force of the friction block 500 pressing against the friction ring 400 increases or decreases, thereby changing the magnitude of the friction force during movement. This allows the operator to know that the frictional resistance generated is different at different gear positions, enabling the operator to pay attention to the adjustment range and proportion, avoiding operator errors, and ensuring that subsequent reactance adjustment does not produce errors.

[0046] It should be noted that in this embodiment, the rotating rod 200, the fixed ring 300 and the friction ring 400 are located at the same center. The center of the semi-circular ring 600 and the center of the friction ring 400 are on the same straight line. When the semi-circular ring 600 moves, its center and the center of the friction ring 400 are offset.

[0047] In this embodiment, in order to drive the rotating rod 200 to rotate, a keyway is provided at the top of the rotating rod 200, and a locking block is provided on the top wall of the receiving cavity of the rotating cap 100. The locking block is disposed between the inner walls of the keyway, and torque is transmitted through the locking block and the keyway.

[0048] In this embodiment, in order for the semi-circular ring 600 to drive the friction block 500 to move along the diameter direction of the semi-circular ring 600, as follows: Figure 6 As shown, a hexagonal prism 800 is fixedly installed on the inner wall of the cavity of the rotating cap 100. The friction block 500 is sleeved on the outer surface of the hexagonal prism 800. The hexagonal shape of the hexagonal prism 800 prevents the friction block 500 from rotating and allows it to move along the central axis of the hexagonal prism 800. To limit the installation position of the semicircular ring 600, as shown... Figure 7 and Figure 8As shown, the upper surface of the fixed ring 300 has a notch 310, and two recessed grooves 311 are symmetrically formed on the upper surface of the notch 310. Two limiting blocks are symmetrically fixedly installed on the lower surface of the semicircular ring 600. The two limiting blocks are slidably installed between the inner walls of the two recessed grooves 311. A sliding sleeve 900 is slidably fitted on the outer surface of the hexagonal column 800. A rod 910 is fixedly installed on the lower surface of the sliding sleeve 900. The upper surface of the semicircular ring 600 has a first guide groove 610, and the rod 910 is slidably installed with the inner wall of the first guide groove 610. The outer surface of the hexagonal column 800 is fitted with... A first spring 1000 is provided. One end of the first spring 1000 is fixedly connected to the outer surface of the friction block 500, and the other end of the first spring 1000 is fixedly connected to the outer surface of the sliding sleeve 900. The semicircular ring 600 moves along the central axis of the groove 311, and then, through the cooperation of the rod 910 and the first guide groove 610, the sliding sleeve 900 moves closer to the friction ring 400. This causes the sliding sleeve 900 to drive the friction block 500 to move closer to the friction ring 400 through the first spring 1000, thereby increasing the force of the friction block 500 against the friction ring 400 and thus increasing the friction between the two.

[0049] It is important to note that, such as Figure 9 As shown, when the semicircular ring 600 shifts upwards towards the fixed ring 300, its eccentricity is upwards. Therefore, as the friction block 500 moves along the outer circumference of the friction ring 400, the friction resistance increases as the friction block 500 gradually approaches the friction ring 400. Conversely, when the semicircular ring 600 shifts downwards towards the fixed ring 300, its eccentricity is downwards. At this time, as the friction block 500 moves along the outer circumference of the friction ring 400, it gradually moves away from the friction ring 400, so the friction resistance decreases. This setting generates different frictional force changes, thereby reminding the operator whether the adjusted setting is in the corresponding position.

[0050] In order to move the semi-circular ring 600 along the central axis of the settling tank 311, such as Figure 8 and Figure 9 As shown, a lead screw 1700 is rotatably mounted between the inner walls of opposite ends of one of the two settling tanks 311. The lead screw 1700 passes through the outer surface of the limiting block and is threadedly connected to it. One end of the lead screw 1700 passes through the outer surface of the fixing ring 300 and is fixedly mounted with a gear 1800. An arc-shaped piece 700 is provided on the upper surface of the notch 310, as shown. Figure 10As shown, multiple insertion rods 720 are fixedly installed on the lower surface of the arc-shaped piece 700, and multiple insertion holes 312 are formed on the upper surface of the notch 310. The insertion rods 720 are slidably inserted between the inner walls of the insertion holes 312. A rack 1900 is fixedly installed on the lower surface of the arc-shaped piece 700. The rack 1900 meshes with a gear 1800. When the arc-shaped piece 700 moves up and down along the central axis of the insertion holes 312, the arc-shaped piece 700 drives the rack 1900 to move up and down. The rack 1900 drives the lead screw 1700 to rotate forward and backward through the gear 1800, thereby... Figure 9 As shown, the semicircular ring 600 is moved up and down along the central axis of the sink 311, so that the eccentricity between the semicircular ring 600 and the friction ring 400 is adjusted up and down.

[0051] In order to move the arc-shaped piece 700 up and down along the central axis of the socket 312, such as Figure 4 and Figure 5 As shown, a T-shaped groove 110 is formed on the outer circumference of the rotating cap 100. A push block 1200 is slidably installed between the inner walls of the T-shaped groove 110. A guide post 1500 is fixedly installed on the outer surface of the push block 1200 near the arc plate 700. A through groove 120 is formed on the inner wall of the T-shaped groove 110. A second guide groove 710 is formed on the outer circumference of the arc plate 700. The guide post 1500 is slidably installed through the through groove 120 and the inner wall of the second guide groove 710. When the operator manually pushes the push block 1200 up and down, the arc plate 700 will move up and down through the cooperation of the guide post 1500 and the second guide groove 710.

[0052] Because the arc-shaped piece 700 needs to be positioned at a required height when moving up and down, therefore... Figure 5 As shown, the T-shaped slide 110 has multiple symmetrical slots 130 between the inner walls on opposite sides. The push block 1200 has two elastic pieces 1300 symmetrically arranged on the outer surfaces on opposite sides. The elastic pieces 1300 are located inside the slots 130. Through the elastic deformation capability of the elastic pieces 1300, when the operator does not manually push the push block 1200, the elastic pieces 1300 restrict the position of the push block 1200 through the slots 130, so that the arc piece 700 will not move up and down arbitrarily.

[0053] To prevent the operator from accidentally touching the push block 1200 and causing the position of the arc-shaped piece 700 to change while the nut 100 is rotating, such as... Figure 12 As shown, the outer surface of the push block 1200 near the arc plate 700 has a mounting groove 1210. Symmetrical through holes 1220 are formed on the inner walls of the mounting groove 1210 on opposite sides. A top block 1400 is slidably inserted into the inner wall of the through hole 1220. One end of the top block 1400 abuts against the outer surface of the elastic plate 1300. Figure 11 As shown, when the cap 100 rotates, the top block 1400 abuts against the outer surface of the elastic sheet 1300, thereby ensuring that the elastic sheet 1300 will not deform elastically and will not slip off the latch 130.

[0054] In order to control whether the top block 1400 can abut against the outer surface of the elastic sheet 1300 and release the pressure on the elastic sheet 1300, such as Figure 12 and Figure 13 As shown, a support plate 1600 is provided inside the mounting groove 1210. Two sliding columns 1620 are symmetrically fixedly installed between the inner walls of the support plate 1600. An inclined groove 1410 is formed on the outer surface of the other end of the top block 1400. The sliding column 1620 is slidably installed with the inner wall of the inclined groove 1410. Two second springs 1630 are symmetrically fixedly connected to the outer surface of one side of the support plate 1600. The other ends of the two second springs 1630 are fixedly connected to the inner wall of the mounting groove 1210. When the support plate 1600 moves away from the friction ring 400, the two top blocks 1400 move closer to each other through the cooperation of the sliding column 1620 and the inclined groove 1410, thereby releasing the pressure on the elastic sheet 1300. In order to make the support plate 1600 move away from the friction ring 400, as follows: Figure 14 , Figure 15 and Figure 16 As shown, a push rod 1610 is fixedly installed on the outer surface of the other side of the support plate 1600. The push rod 1610 passes through the through groove 120. A wedge block 1100 is fixedly installed on the upper surface of the arc plate 700. The outer surface of the wedge block 1100 is provided with an angle. One end of the push rod 1610 abuts against the outer surface of the angle. When the nut 100 returns to the initial position, it can drive the push rod 1610 to abut against the angle of the wedge block 1100, thereby driving the support plate 1600 to move away from the friction ring 400. Conversely, when the nut 100 rotates, the push rod 1610 leaves the angle of the wedge block 1100. At this time, under the elastic force of the two second springs 1630, the two push blocks 1400 move away from each other, pressing the elastic plate 1300 tightly.

[0055] To limit the installation position of the support plate 1600, a limiting post is fixedly connected to the outer surface of one side of the support plate 1600. The limiting post is inserted into the push block 1200 and slidably installed therewith.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
