Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage dynamic reactive power compensation devices, in particular to a heat dissipation component of a high-voltage dynamic reactive power compensation device. Background Art

[0002] High-voltage dynamic reactive power compensation device, namely static synchronous compensator, also known as static reactive power generator. Because its switching device is IGBT, its dynamic compensation effect is incomparable to the early synchronous phase condenser, capacitor and reactive power compensation device. Reactive power compensation device has become an important equipment in modern flexible AC transmission system with its lower harmonics, higher efficiency and faster dynamic response.

[0003] After searching, the prior art has a publication number of CN215934257U, which discloses a heat dissipation device for a high-voltage compensation cabinet, including a cabinet, a heat dissipation hole, a receiving cavity, a dust collecting bin, a first dustproof net, a heat dissipation fan, a fastening plate, a second dustproof net, a dust outlet, a sealing plate, a support plate, and a switch door. The heat dissipation holes are provided on the two side walls of the cabinet, the receiving cavity and the dust collecting bin are provided on the two side walls of the cabinet, the first dustproof net is arranged in the receiving cavity, the heat dissipation fan is provided on the top of the cabinet, the fastening plate is fixed to the top of the cabinet by screws, the second dustproof net is fixed to the through groove on the fastening plate by screws, the dust outlet is provided on the side wall of the dust collecting bin, the dust outlet is rotatably connected to the sealing plate by a shaft pin, and the support plate is fixed in the cabinet. The utility model effectively solves the problem that the compensation cabinet can prevent dust while dissipating heat.

[0004] However, the high-voltage dynamic reactive power compensation device needs to use a heat dissipation device to dissipate the heat inside the air during long-term operation to prevent the internal temperature of the high-voltage dynamic reactive power compensation device from rising due to the heat generated by the operation of the components. The high temperature affects the operation of the components and their service life. The traditional heat dissipation device uses a heat dissipation window and a fan combination to dissipate the air of the high-voltage dynamic reactive power compensation device. However, the long-term use of the fan to discharge the high-temperature air inside the compensation device through the heat dissipation window can easily cause dust to accumulate inside and outside the surface of the heat dissipation window. The dust accumulation causes the ventilation effect of the heat dissipation window to decrease. Therefore, a heat dissipation component for a high-voltage dynamic reactive power compensation device is needed. Utility Model Content
