Description

Technical Field

[0002] A Static Var Generator (SVG) is a self-commutated bridge circuit that is connected to the power grid via a reactor or directly in parallel. By adjusting the phase and amplitude of the AC output voltage of the bridge circuit, or by directly controlling its AC current, the circuit can absorb or generate reactive power that meets the requirements, thereby achieving dynamic reactive power compensation.

[0039] In some embodiments of this utility model, the container body 100 is further provided with at least a portion of a water-cooled heat exchange module 500 within the control cavity 120. The water-cooled heat exchange module 500 includes a cold water output end and a hot water return end. The container body 100 is provided with a cold water main pipe (not shown in the figure) and a hot water main pipe 530. The first end of the cold water main pipe is connected to the cold water output end of the water-cooled heat exchange module 500, and the first end of the hot water main pipe 530 is connected to the hot water return end of the water-cooled heat exchange module 500. The first ends of the cold water main pipe and the first ends of the hot water main pipe 530 are both located in the control cavity 120, and the tail ends of the cold water main pipe and the hot water main pipe 530 are both located in the power cavity 110. The power module 200 is provided with at least one heat exchanger. The water-cooled input end of the heat exchanger is connected to the cold water main pipe, and the water-cooled output end of the heat exchanger is connected to the hot water main pipe 530.

[0040] In the water-cooled heat exchange module 500, water is used as the heat exchange medium. External airflow or water flow can be used to exchange heat with the internally circulating water medium. Specifically, each power unit is equipped with a corresponding heat exchanger. The switching tube makes thermal contact with the heat exchanger to exchange heat. The water-cooled input end of each heat exchanger is connected to the cold water main pipe, and the water-cooled output end of each heat exchanger is connected to the hot water main pipe 530. The cold water output end of the water-cooled heat exchange module 500 outputs cold water at a lower temperature to the cold water main pipe. The cold water absorbs heat through each heat exchanger and is then transferred to the hot water main pipe 530. The hot water main pipe 530 then returns the hot water at a higher temperature to the hot water return end of the water-cooled heat exchange module 500. The hot water releases heat in the water-cooled heat exchange module 500, thus lowering its temperature. Specifically, the hot water main pipe 530 can be located above the power valve tower 210, while the cold water main pipe is located below the power valve tower 210.

[0041] Specifically, the water-cooled heat exchange module 500 includes an air-cooled heat exchanger 510 and a water-cooled heat exchanger 520 that are configured to exchange heat with each other. The water-cooled heat exchanger 520 is located in the control cavity 120. The first end of the cold water main pipe is connected to the cold water output end of the water-cooled heat exchanger 520, and the first end of the hot water main pipe 530 is connected to the hot water return end of the water-cooled heat exchanger 520. The air-cooled heat exchanger 510 is disposed outside the container body 100.

[0042] The air-cooled heat exchanger 510 includes multiple heat dissipation fins and a fan. The heat dissipation fins are arranged on the outside of the container body 100, and adjacent heat dissipation fins form a heat exchange air duct. The water-cooled heat exchanger 520 includes a hot water pipe that can pass back and forth through the heat dissipation fins and is in thermal contact with the heat dissipation fins. Both ends of the hot water pipe enter the container body 100. The first end of the hot water pipe serves as the cold water output end, and the second end serves as the hot water return end. The fan guides the airflow through the heat exchange air duct, and the airflow quickly dissipates heat from the heat dissipation fins.

[0043] In some embodiments of this utility model, such as Figure 1 As shown, a reactor 610, a soft starter assembly 620, a lightning rod 630, and an incoming line disconnect switch 640 are also provided outside the container body 100. The reactor 610, the soft starter assembly 620, and the incoming line disconnect switch 640 are connected in sequence. The lightning rod 630 is connected to the soft starter assembly 620 and the incoming line disconnect switch 640 respectively. The reactor 610 is connected to the tail end of the electrical coupling bushing 140.

[0044] After the container body 100 is placed on site, the user can install a reactor 610, a soft starter assembly 620, a lightning rod 630 and an incoming line disconnect switch 640 on the outside of the container body 100. The incoming line disconnect switch 640 is used to connect with external electrical equipment.

[0045] In some embodiments of this utility model, such as Figure 1 As shown, a fence 650 is also provided outside the container body 100. Both ends of the fence 650 are in contact with the outer wall of the container body 100 to define an isolation area 651. The reactor 610 and the soft starter assembly 620 are located inside the isolation area 651, while the lightning rod 630 and the incoming line disconnect switch 640 are located outside the isolation area 651.

[0046] The fence 650 can be formed from a fence made of conventional alloy, wood, resin or cement. The fence 650 defines an isolation area 651 to prevent users from entering the isolation area 651 and coming into contact with the reactor 610 and the soft starter assembly 620.

[0047] In some embodiments of this utility model, the soft start component 620 includes a soft start resistor 621 and a soft start disconnect switch 622 connected in parallel. In the initial stage of startup, the soft start disconnect switch 622 is open, and the soft start resistor 621 is connected to the power component and the power grid line to limit the impact of instantaneous current on the component. After the SVG device is running stably, the soft start disconnect switch 622 is closed to bypass the soft start resistor 621.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
