Description

Technical Field

[0001] The utility model specifically relates to the technical field of static reactive power generating devices, in particular to a static reactive power generating device with a long service life. Background Art

[0002] A static VAR generator connects a self-commutated bridge circuit to the power grid through a reactor or directly in parallel, adjusts the phase and amplitude of the output voltage on the AC side of the bridge circuit, or directly controls the current on its AC side, so that the circuit absorbs or emits reactive power that meets the requirements, thereby achieving the purpose of dynamic reactive power compensation.

[0003] When traditional static VAR generators are used for a long time, steam and water will accumulate in the box due to changes in the external environment. When the accumulated water falls on the connection between components, it will cause a short circuit or even burn out. Therefore, during long-term use, the inside of the box needs to be regularly inspected, which is troublesome and increases the cost of using the static VAR generator.

[0004] After searching, Chinese patent publication number CN202021987871.4 discloses a static reactive power generating device, including a main box body, an aluminum base plate welded inside the main box body, a circulating water pipe welded on the back of the aluminum base plate, a circulating pump provided at the lower part of the main box body, and the left end of the circulating water pipe is connected to the left end of the circulating pump through a first hose. The utility model has a main box body, an aluminum base plate welded inside the main box body, a circulating water pipe welded on the back of the aluminum base plate, the inside of the circulating water pipe is filled with cooling oil, and the circulating pump can circulate the cooling oil inside the circulating water pipe to play a heat dissipation role. A plurality of first partitions are welded on the front of the aluminum base plate for fixing the internal components of the static reactive power generating device, a second partition is welded on the middle of the front of the aluminum base plate, and vertical plates are respectively welded on the left and right sides of the second partition, and heat dissipation holes are evenly opened on the vertical plates, and the vertical plates are used to install components;

[0005] When the structure in the above patent is in use, the circulating pump realizes the effect of circulating and cooling the cooling oil inside the circulating water pipe; thus, after long-term use, when the cooling efficiency of the circulating oil decreases, the cooling oil needs to be replaced, and when the structure in the above patent is cooling the inside of the main box, it is subject to temperature changes, so a large amount of steam and water will accumulate inside the main box. Although the above patent can achieve heat dissipation inside the main box, it will also cause water accumulation inside the main box. Therefore, the structure in the above patent still has certain limitations.

[0006] In view of the above situation, we provide a static reactive power generating device with a long service life. In this device, there is a gap of 10-15 cm between the bottom frame and the bottom of the box, which can effectively reduce the steam from the bottom of the box from entering the box and causing the steam to gather inside the box. A plurality of fans are also fixedly installed inside the box, and the fans are used to effectively blow air onto the components, which can effectively reduce the temperature of the components when in use. By installing the components on the U-shaped frame, when replacing the components, effective disassembly and installation can be achieved by disassembly. Utility Model Content
