A dynamic voltage regulation device for high-penetration new energy power grids

Abstract

This utility model provides a dynamic voltage regulation device for high-penetration new energy power grids, belonging to the field of regulation devices. It includes a regulation cabinet with a regulator inside the upper part and assembly components inside the lower part. Expansion components are installed between the assembly components. When the regulator bracket needs to be replaced, the top plates on both sides are pulled in opposite directions, causing them to slide within the slots, which in turn causes the retaining plate to detach from the retaining plate and slide into the slot. Pressing the pressure plates on both sides causes them to slide into the sliding grooves, which in turn causes the insert plate to slide into the sliding grooves. This compresses the second hydraulic rod and the second spring, inserting the insert plate into the aligned slot. Releasing the pressure on the pressure plates causes the second hydraulic rod and the second spring to push the sliding plate outwards, causing the insert plate to insert into the aligned slot. This completes the rapid installation of the regulation mounting bracket and improves the convenience of interface expansion.

Description

Technical Field

[0001] This utility model relates to the field of regulating devices, and more specifically, to a dynamic voltage regulating device for high-penetration new energy power grids. Background Technology

[0002] A dynamic voltage regulator (DVR) is connected in series between the power supply and the sensitive load. It is a voltage compensation device implemented using power electronics technology. Its main compensation target is voltage dips, and it can also compensate for various voltage quality problems such as harmonics, flicker, and asymmetry. When a voltage dip occurs, the DVR can compensate the voltage dip back to the normal value within milliseconds. The DVR operates in bypass mode when the voltage is normal, and provides the power consumption required for the normal operation of the load when the voltage dips.

[0003] A search revealed that Chinese patent CN109713569A discloses a "Dynamic Voltage Adjustment Device for Convenient Wiring," comprising a base, a door, and a partition mechanism. The upper end of the base is connected to a body, and a first hinge is installed on one side of the body. The door is fixed to the side of the first hinge away from the body, and an observation window is fixed to the top inner side of the door. The partition mechanism is located in the middle of the inner side of the body, and seat plates are connected to both sides of the outer wall of the partition mechanism. An mounting plate is installed at the lower end of the seat plate, and electronic components are housed inside the mounting plate. Terminal blocks are connected to the bottom outer side of the electronic components, and pressure plates are installed inside the terminal blocks. This dynamic voltage adjustment device for convenient wiring has a base, which is vertically and horizontally distributed with the body. The base and body are welded together as a single unit, and both are made of stainless steel, providing good rigidity and preventing breakage or collapse during use. However, it still has the following drawbacks: (1) The existing power grid dynamic regulation process requires the use of a variety of regulation components. Different regulation components require different connectors for installation. The replacement of the connectors in the existing regulation equipment cabinet requires the removal of multiple bolts at both ends. Light is also blocked in the small cabinet, which affects the convenience of replacement. (2) The existing power grid dynamic regulation has a single type of regulation component, and the regulation equipment cabinet can only be used for the installation and regulation of a single type of equipment, which reduces the versatility of regulation.

[0004] Therefore, we have made improvements to this by proposing a dynamic voltage regulation device with high penetration into new energy power grids. Utility Model Content

[0005] The purpose of this utility model is to address the problem that the existing dynamic regulation process of the power grid requires the use of various regulation components, and different regulation components require different connectors for installation.

Light is also blocked in the small cabinet, which affects the convenience of replacement. In addition, the existing dynamic regulation of the power grid has a single model of regulation components, and the regulation equipment cabinet can only be used for the installation and regulation of a single type of equipment, which reduces the versatility of regulation.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0019] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] like Figure 1-4 As shown, this embodiment proposes a dynamic voltage regulation device for high-penetration new energy power grids, including a regulating cabinet 1. A regulator 2 is provided inside the upper end of the regulating cabinet 1, and an assembly component is provided inside the lower end of the regulating cabinet 1. An expansion component is installed between the assembly components. The assembly includes a base plate 301 disposed on the inner walls of both sides of the lower end of the regulating cabinet 1, a side plate 302 inserted between the base plates 301, and an adjuster bracket 303 fitted between the side plates 302 on both sides. The expansion component includes slots 401 on the front and rear sides of the adjuster bracket 303. A plug plate 402 is detachably inserted into the slot 401, and an adjustment mounting bracket 410 is installed on the outside of the plug plate 402.

[0022] like Figure 2 As shown, the side plate 302 has a slot 304 inside, and a top plate 305 is movably installed inside the slot 304. When the adjuster bracket 303 needs to be replaced, the top plates 305 on both sides are pulled in opposite directions, so that they slide in the slot 304, causing the clamping plate 306 to disengage from the clamping slot 307 and slide into the slot 304, which compresses the first hydraulic rod 308 and the first spring 309 to make them contract.

[0023] like Figure 2As shown, a retaining plate 306 is provided at the end of the top plate 305 away from the adjuster bracket 303. The side wall of the seat plate 301 is provided with a retaining groove 307 that cooperates with the retaining plate 306. When the tension on the top plate 305 is released, the first hydraulic rod 308 and the first spring 309 push the top plate 305 outward, causing the retaining plate 306 to insert into the aligned retaining groove 307.

[0024] like Figure 2 As shown, a first hydraulic rod 308 is provided at the end of the top plate 305 away from the clamping plate 306. A first spring 309 is fitted on the outer wall of the first hydraulic rod 308. The first hydraulic rod 308 and the first spring 309 compress and contract the first hydraulic rod 308. When the clamping plate 306 is completely disengaged from the slot 307, the adjuster bracket 303 can be pulled forward to disengage the two side plates 302 from the seat plate 301, thus completing the quick disassembly of the adjuster bracket 303. To replace the adjuster bracket 303 of the required model, align the two side plates 302 with the seat plate 301, release the tension on the top plate 305, and the first hydraulic rod 308 and the first spring 309 push the top plate 305 outward, causing the clamping plate 306 to insert into the aligned slot 307, thus completing the quick replacement and fixation of the adjuster bracket 303.

[0025] like Figure 3 As shown, the insert plate 402 has grooves 403 on both sides inside. A sliding plate 404 is movably installed inside the grooves 403. When it is necessary to expand the adjuster bracket 303, the insert plate 402 installed on the side wall of the adjustment mounting bracket 410 is aligned with the slot 401, and the pressure plates 407 on both sides are pressed to slide into the grooves 403, thereby driving the insert plate 405 to slide into the grooves 403.

[0026] like Figure 4 As shown, a plate 405 is provided at one end of the slide plate 404 near the adjuster bracket 303. The side wall of the slot 401 is provided with a groove 406 that cooperates with the plate 405. The plate 405 is inserted into the aligned groove 406, which can complete the quick installation of the adjustment mounting bracket 410 and improve the convenience of interface expansion.

[0027] like Figure 3 As shown, a pressure plate 407 is provided on the outer wall of the end of the slide plate 404 away from the insert plate 405. A second hydraulic rod 408 is installed on the back of the pressure plate 407. A second spring 409 is fitted on the outer wall of the second hydraulic rod 408. When the second hydraulic rod 408 and the second spring 409 are compressed and contracted, the insert plate 402 is inserted into the aligned slot 401. When the pressure on the pressure plate 407 is released, the second hydraulic rod 408 and the second spring 409 push the slide plate 404 outward, causing the insert plate 405 to be inserted into the aligned groove 406, thus completing the quick installation of the adjustment mounting bracket 410.

[0028] Specifically: When the regulator bracket 303 needs to be replaced, pull the two top plates 305 in opposite directions, causing them to slide within the slot 304. This causes the locking plate 306 to disengage from the slot 307 and slide into the slot 304. The first hydraulic rod 308 and the first spring 309 are then compressed and contracted. When the locking plate 306 is completely disengaged from the slot 307, the regulator bracket 303 can be pulled forward to disengage the two side plates 302 from between the seat plate 301, completing the quick disassembly of the regulator bracket 303. To replace the required regulator bracket 303, align the two side plates 302 with the seat plate 301, release the tension on the top plate 305, and the first hydraulic rod 308 and the first spring 309 push the top plate 305 outward, causing the locking plate 306 to insert. Aligned slots 307 allow for quick replacement and fixation of the regulator bracket 303. When the regulator bracket 303 needs to be expanded, align the insert plate 402 mounted on the side wall of the adjustment mounting bracket 410 with the slot 401, press the pressure plates 407 on both sides to slide them into the slide groove 403, causing the insert plate 405 to slide into the slide groove 403, compressing and contracting the second hydraulic rod 408 and the second spring 409, inserting the insert plate 402 into the aligned slot 401, releasing the pressure on the pressure plate 407, and the second hydraulic rod 408 and the second spring 409 push the slide plate 404 outward, causing the insert plate 405 to insert into the aligned slot 406, thus completing the quick installation of the adjustment mounting bracket 410 and improving the convenience of interface expansion.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
