Description

Technical Field

[0001] This utility model relates to the technical field of devices for adjusting, eliminating or compensating reactive power in a network, specifically an intelligent high-power thyristor switching device. Background Technology

[0002] Intelligent high-power thyristor switching devices are electronic power devices used in power systems to switch capacitors and other equipment. They are electronic switches without mechanical contacts and use zero-crossing switching technology, which allows the capacitor bank to be put into operation when the voltage crosses zero and to be taken out of operation when the current crosses zero. In the power systems of some large factories, thyristor switching devices can quickly respond to load changes and ensure the stable operation of the power system.

[0003] To ensure the normal operation of intelligent high-power thyristor switching switches, they need to be protected. Therefore, a protective housing is usually installed on the outside of the thyristor switching switch. When the thyristor switching switch is under maintenance, the housing needs to be disassembled first in order to inspect the internal electronic components. Currently, the protective housing is relatively troublesome to disassemble, which takes a long time during maintenance and thus affects the maintenance efficiency of the thyristor switching switch.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1 to 5 This utility model provides a new technical solution: an intelligent high-power thyristor switching switch, including a protective housing 1. Electronic components are housed inside the protective housing 1. The electronic components have existing structures and connection methods, so they will not be explained in detail. A connecting wire 2 is provided on the front side of the protective housing 1, extending into the interior of the protective housing 1. The connecting wire 2 is electrically connected to the electronic components. A switch plate 3 is provided inside the protective housing 1, positioned on the left side. Rotating grooves 4 are provided on both the front and rear walls of the protective housing 1. Rotating columns 5 are fixedly connected to the front and rear sides of the switch plate 3. The two rotating columns 5 extend into the interior of the two rotating slots 4 respectively. The top wall of the protective shell 1 is provided with an installation slot 6. The front and rear walls of the installation slot 6 are provided with snap-fit ​​slots 7. The switch plate 3 is provided with a snap-fit ​​mechanism. The snap-fit ​​mechanism enables the switch plate 3 to be adapted to the protective shell 1 to form a snap-fit. The snap-fit ​​mechanism includes a sliding block slot 8, a connecting slot 9, a sliding block 10, a sliding plate slot 11, a snap-fit ​​slot 12, a control slot 13, a connecting plate 14, a snap-fit ​​block 15, a control block 16, and a spring 17.

[0035] Furthermore, the sliding block groove 8 is formed inside the switch plate 3, and the top wall of the sliding block groove 8 extends out of the upper side of the switch plate 3. The connecting groove 9 is formed inside the switch plate 3 and is located below the sliding block groove 8. The interior of the connecting groove 9 is connected to the interior of the sliding block groove 8. The sliding block 10 is slidably connected to the interior of the sliding block groove 8. The slide plate groove 11 is formed inside the sliding block 10 and is located at the front. The locking groove 12 is formed on the front side of the sliding block 10 and is located above the slide plate groove 11. The control groove 13 is formed on the front side of the sliding block 10 and is located below the slide plate groove 11. The slide plate groove 11 is connected to the sliding block 10 and is located below the slide plate groove 11. The internal parts of the locking slot 12 and the control slot 13 are connected. The connecting plate 14 is slidably connected to the inside of the sliding plate slot 11. The locking block 15 is slidably connected to the inside of the locking slot 12. The locking block 15 is locked to the front locking slot 7. The locking block 15 is fixedly connected to the upper side of the connecting plate 14. The control block 16 is slidably connected to the inside of the control slot 13. The control block 16 is fixedly connected to the lower side of the connecting plate 14. The spring 17 is fixedly connected to the rear side of the control block 16. The rear end of the spring 17 is fixedly connected to the rear wall of the control slot 13. The sliding block 10 is also provided with a sliding plate slot 11 at the rear position. The front and rear sliding plate slots 11 and their connection structures are the same and symmetrically arranged.

[0036] Furthermore, when it is necessary to inspect the electronic components inside the protective housing 1, the switch plate 3 needs to be opened. The operator presses the front control block 16 backward, and at the same time, the spring 17 begins to compress. The front control block 16 drives the front connecting plate 14 to move backward, and the front connecting plate 14 drives the front locking block 15 to move backward. Then, the front locking block 15 moves into the locking slot 12, and the locking state between the locking block 15 and the locking slot 7 is released. At the same time, the rear control block 16 is pressed forward. As can be seen from the above, the locking state between the rear locking block 15 and the rear locking slot 7 is released, and then... The sliding block 10 is moved downwards, and a part of the upper side of the sliding block 10 moves from the inside of the mounting groove 6 to the inside of the sliding block groove 8. This allows the switch plate 3 to be pulled open. The switch plate 3 will rotate around the two rotating columns 5 as the center. Then, the staff can inspect the electronic components inside the protective housing 1. After the inspection is completed, the switch plate 3 can be snapped onto the protective housing 1 in the above manner. In this way, the protective housing 1 can be opened simply and quickly, so that the disassembly and installation of the housing will not take a long time during the inspection, thereby improving the maintenance efficiency of the thyristor switching switch.

[0037] Working principle: When it is necessary to inspect the electronic components inside the protective housing 1, the switch plate 3 needs to be opened. The operator presses the front control block 16 backward, and at the same time, the spring 17 begins to compress. The front control block 16 drives the front connecting plate 14 to move backward, and the front connecting plate 14 drives the front locking block 15 to move backward. Then, the front locking block 15 moves into the locking slot 12, and the locking state between the locking block 15 and the locking slot 7 is released. At the same time, the rear control block 16 is pressed forward. As can be seen from the above, the locking state between the rear locking block 15 and the rear locking slot 7 is released, and then the sliding block 10 moves downward. Then, a part of the upper side of the sliding block 10 moves from the inside of the mounting slot 6 to the inside of the sliding block slot 8, which can pull the switch plate 3 to open it. The switch plate 3 will rotate around the two rotating columns 5 as the center. Then, the operator can inspect the electronic components inside the protective housing 1. After the inspection is completed, the switch plate 3 can be locked back into the protective housing 1 in the above manner.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
