Description

Technical Field

[0001] The utility model relates to the technical field of static var generators, in particular to a protection device for a static var generator. Background Art

[0002] The working principle of a static var generator mainly takes a dual digital signal processor as the core, combines real-time data acquisition technology and dynamic tracking technology, continuously monitors the voltage and current of the power grid and the system, and performs a series of operations. These operation results are output and compensated to the system or the power grid through a converter unit with IGBT as the core, which can quickly and continuously adjust the reactive power of the system. The static var generator has a wide range of applications in multiple fields. SVG can also effectively control the power quality of the power grid, including harmonic control, voltage dip control, and voltage fluctuation control, etc. Finally, in the field of new energy power grids, especially in wind power and photovoltaic power stations, due to the instability of these new energy power generations, SVG is widely used to balance the power grid load.

[0003] At present, the heat dissipation effect of the existing protection device for a static var generator is not ideal when working in an outdoor high-temperature environment, and it is easy to increase the loss rate of internal components during long-term use. Based on these problems, Chinese Patent CN218242739U discloses a protection device for a static var generator, which improves the structure of the traditional protection device for a static var generator, adds an independent heat dissipation device and a solar power generation system for its function, enables the static var generator to be fully cooled when working outdoors, saves the power consumed by the heat dissipation device at the same time, and improves the working efficiency of the static var generator.

[0004] The heat dissipation device in the cabinet of this static var generator is not provided with a dust-proof mechanism. Therefore, dust in the external air will pass through the heat dissipation device and enter the interior of the cabinet of the static var generator. When the dust adheres to the surface of the electronic components inside the cabinet, it will not only affect the normal heat dissipation of the electronic components inside the static var generator, but also reduce the service life of this static var generator.
