Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage solid-state soft starting, and in particular to a high-voltage solid-state soft starting device equipped with an adaptive adjustment electrode structure. Background Art

[0002] High-voltage solid-state soft starters achieve smooth starting of motors and mechanical loads and reduce starting current by adopting technical means such as voltage reduction or frequency conversion. Conventional high-voltage solid-state soft starters use semi-controlled devices, thyristors, also known as thyristors, and their electronic control circuits. They adopt an AC-AC voltage regulation method. Their output can adjust the voltage but not the frequency. When the motor is started, the starting output torque is small and the starting current is large, which is suitable for medium and light loads. Its main function is to gradually increase the voltage and frequency during the starting process of the motor to keep the starting current of the motor at a low level, while ensuring sufficient starting torque, thereby reducing the impact on the power grid.

[0003] For example, the invention with publication number CN105577036B8 discloses a trolley-type medium- and high-voltage solid-state motor soft starter. The invention adopts an integrated design, which is convenient for maintenance. With the assistance of an industry-standard transfer chassis, the device can be pulled out by manpower. It has a simple structure and is easy and quick to use and install. However, in the actual use of such devices, due to the long-term use of the contact electrode of the device, a layer of metal oxide or carbon film may form on its surface. This film will hinder the passage of current, thereby generating contact resistance, which will affect the normal use of the equipment.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a high-voltage solid-state soft-start device equipped with an adaptive adjustment electrode structure is proposed. Summary of the invention

[0016] The present invention provides a high-voltage solid-state soft-start device equipped with an adaptive adjustment electrode structure, which has the following beneficial effects:

[0017] 1. According to the present invention, when the contact surface of the first contact electrode and the second contact electrode increases due to oxidation after working for a long time, the motor will drive the reciprocating screw to rotate through the driving shaft, the driving gear, the driven gear and the one-way bearing, so that the movable seat can move horizontally, so that the fixed cylinder moves to between the first contact electrode and the second contact electrode. In this process, the guide plate will contact the sliding column, so as to automatically adjust the height of the guide frame, and the first contact electrode and the second contact electrode will adaptively separate and avoid, so that the sandpaper sleeve can be used to scrape and clean the contact surface between the first contact electrode and the second contact electrode, reduce the oxide attached to the surface, and help to reduce the resistance during subsequent contact, and use the elastic pad to increase the contact force between the sandpaper sleeve and the electrode surface, so as to further improve the cleaning effect, and as the reciprocating screw continues to rotate, when the movable seat moves back, the guide plate will avoid the sliding column, and at this time the reset spring will squeeze the guide frame, so that the second contact electrode contacts the first contact electrode, so that the electrodes can be automatically docked after cleaning, which is conducive to improving the convenience during maintenance.

[0018] 2. When the motor of the present invention drives the driving shaft to rotate, it also drives the fan blades to rotate, so that negative pressure is formed on the upper part of the fixed box. At this time, the first one-way valve is open, and negative pressure can be formed inside the fixed cylinder through the first guide tube and the first sliding tube, so that the powder generated by the grinding and scraping of the sandpaper sleeve can be sucked out through the suction holes on the upper and lower sides, which is beneficial to maintaining the cleanliness of the environment when the equipment is working, and the filter can also be used to filter impurities so as to concentrate on cleaning the impurities. Moreover, the first guide tube is slidably connected to the first sliding tube, so that the movable seat can be limited and guided, which is beneficial to maintaining the stability of the movable seat when moving.

[0019] 3. After cleaning, the present invention can also reverse the motor through the controller. At this time, since the drive shaft rotates in the opposite direction, the one-way bearing will be converted from a locked state to an active state, so that no transmission will be performed, and the movable seat can stop moving. At the same time, the fan blades can inhale external air into the upper end of the fixed box due to the reversal, forming high pressure. At this time, the first one-way valve is closed and the second one-way valve is opened, and the airflow can be transported to one side of the lining partition through the second guide pipe and the second sliding pipe, and blown to the outside of the second contact electrode through the air jet hole, which is beneficial to speed up the air flow rate outside the second contact electrode, thereby improving the heat dissipation performance of the pole piece when the pole piece does not need to be cleaned.

[0020] When the movable seat moves toward the electrode again, the inclined surface of the teeth of the ratchet wheel will contact the inclined surface of the teeth of the tooth plate, and the clamping plate will block the tooth plane of the ratchet wheel under the action of gravity. Therefore, under the guidance of the inclined surface, there will be a certain vertical component force to push the tooth plate upward, so that the tooth plate is separated from the ratchet wheel, so that the fixed cylinder will not rotate. Therefore, when cleaning the electrode surface, the outer position of the sandpaper sleeve can be automatically adjusted, so that the outer side of the sandpaper sleeve can be fully utilized, and the replacement and maintenance cycle can be extended. At the same time, since the angle of each rotation is certain, after the rotation adjustment, the hole position of the fixed cylinder and the outer side of the rotating sleeve can be kept aligned, so as to avoid blockage due to misalignment.

At this time, the reset spring 710 will squeeze the guide frame 5, so that the second contact electrode 6 contacts the first contact electrode 4, so that the electrodes can be automatically docked after cleaning.

The ratchet 1001 is fixed to the outer side of one end of the rotating sleeve 712, and one end of the movable seat 707 is rotatably connected to the rotating shaft 1002, and the end of the rotating shaft 1002 is connected to an elastic pad 713. The positioning assembly 10 also includes a hanger 1004, a slide bar 1005, a tooth plate 1006 and a compression spring 1007.

[0033] The specific operation is as follows: during the cleaning process, the inclined surface of the teeth of the ratchet 1001 will contact the inclined surface of the teeth of the tooth plate 1006, and at the same time, the clamping plate 1003 will block the tooth plane of the ratchet 1001 under the action of gravity. Therefore, under the guidance of the inclined surface, there will be a certain vertical component force to push the tooth plate 1006 to move up, so that the tooth plate 1006 is separated from the ratchet 1001, and the fixed cylinder 711 will not rotate. Later, when the movable seat 707 moves back, the ratchet 1001 will also move toward the tooth plate 1006, so that the tooth plate The vertical surface of the tooth portion of 1006 contacts the vertical surface of the tooth portion of the ratchet 1001, and the compression spring 1007 pushes the tooth plate 1006 under the limit of the hanger 1004 and the slide bar 1005. Therefore, as the moving seat 707 continues to move, the ratchet 1001 can drive the rotating sleeve 712 to rotate. Therefore, when cleaning the electrode surface, the outer position of the sandpaper sleeve 714 can be automatically adjusted, so that the outer side of the sandpaper sleeve 714 can be fully utilized, the replacement and maintenance cycle is extended, and the fixing cylinder 711 There is a certain friction between the fixed cylinder 711 and the rotating sleeve 712, and rotation will only occur under the action of a larger external force. At the same time, since the angle of each rotation is certain, after the rotation adjustment, the fixed cylinder 711 can also be kept aligned with the hole position on the outside of the rotating sleeve 712 to avoid blockage due to misalignment. Later, when the motor 701 drives the driving shaft 702 to rotate in the opposite direction, the one-way bearing 705 will be converted from a locked state to an active state, so that it will not be transmitted, and the movable seat 707 can be stopped from moving. At the same time, the fan blade 802 can inhale the external air through the filter plate 901 to the upper end of the fixed box 801 due to the reverse rotation, so that it forms a high pressure. At this time, the first one-way valve 803 is closed and the second one-way valve 902 is opened, so that the airflow can be transported to one side of the lining partition 905 through the second guide pipe 903 and the second sliding pipe 904, and blown to the outside of the second contact electrode 6 through the air jet hole 906, which is conducive to accelerating the air flow rate outside the second contact electrode 6, thereby improving the heat dissipation performance of the pole piece when the pole piece does not need to be cleaned.

[0034] In summary, when the high-voltage solid-state soft-start device equipped with an adaptively adjustable electrode structure is used, first, when the contact surface of the first contact electrode 4 on the thyristor group 3 and the second contact electrode 6 at the bottom of the guide frame 5 increases due to oxidation after working for a long time, the motor 701 can be started to drive the reciprocating screw 706 to rotate through the drive shaft 702, the driving gear 703, the driven gear 704 and the one-way bearing 705. At this time, the first guide tube 805 and the first sliding tube 806 are used to limit and guide the movable seat 707, so that the movable seat 707 can be moved horizontally, so that the fixed cylinder 711 moves between the first contact electrode 4 and the second contact electrode 6. At this time, the inclined surface of the teeth of the ratchet 1001 will contact the inclined surface of the teeth of the tooth plate 1006. At the same time, the clamping plate 1003 will block the tooth plane of the ratchet 1001 under the action of gravity. Therefore, under the guidance of the inclined plane, there will be a certain vertical component force to push the tooth plate 1006 upward, so that the tooth plate 1006 is separated from the ratchet 1001. After that, the guide plate 708 will contact the sliding column 709, thereby automatically adjusting the height of the guide frame 5, and the first contact electrode 4 and the second contact electrode 6 will be adaptively separated and avoided, so that the sandpaper sleeve 714 can be used to scrape and clean the contact surface between the first contact electrode 4 and the second contact electrode 6, and the elastic pad 713 can be used to increase the contact force between the sandpaper sleeve 714 and the electrode surface. Secondly, the driving shaft 702 will also drive the fan blade 802 to rotate, so that the upper part of the fixed box 801 forms a negative pressure state. At this time, the first one-way valve 8 03 is in an open state, a negative pressure can be formed inside the fixed cylinder 711 through the first guide tube 805 and the first sliding tube 806, so that the powder generated by the grinding and scraping of the sandpaper sleeve 714 can be sucked out through the suction holes 807 on the upper and lower sides, and the filter 804 can also be used to filter impurities. Then, as the reciprocating screw 706 continues to rotate, when the moving seat 707 moves back, the ratchet 1001 will also move toward the tooth plate 1006, so that the vertical surface of the tooth portion of the tooth plate 1006 contacts the vertical surface of the tooth portion of the ratchet 1001, and at the same time, the compression spring 1007 will push the tooth plate 1006 under the limit of the hanger 1004 and the sliding rod 1005. Therefore, as the moving seat 707 continues to move, the ratchet 1001 can drive the rotating sleeve 712 to rotate. Then, after the movable seat 707 is moved back and reset, the guide plate 708 will avoid the sliding column 709. At this time, the reset spring 710 will squeeze the guide frame 5, so that the second contact electrode 6 contacts the first contact electrode 4, so that the electrodes can be automatically docked after cleaning. Finally, the motor 701 is reversed through the controller, and the fan blade 802 can inhale the external air through the filter plate 901 to the upper end of the fixed box 801 due to the reversal, so that it forms a high pressure. At this time, the first one-way valve 803 is closed and the second one-way valve 902 is opened, so that the airflow can be transported to one side of the lining partition 905 through the second guide pipe 903 and the second sliding pipe 904.And it is blown toward the outside of the second contact electrode 6 through the air jet hole 906, which is helpful to speed up the air flow rate outside the second contact electrode 6.
