Description

Technical Field

[0001] This utility model relates to the field of structural protection technology for converters, specifically to a string converter bracket. Background Technology

[0002] An energy storage converter is a bidirectional current-controllable conversion device that connects an energy storage battery system and the power grid. It can accurately and quickly adjust the voltage, frequency, and power between the power grid and the energy storage system to achieve constant power and constant current charging and discharging, as well as smooth fluctuations in power output.

[0003] String converter brackets are used to mount converters and AC / DC side protection components, enabling the connection between the battery pack and the converter. For example... Figure 1 As shown, the converter is mounted on a converter bracket, with piping and electrical components arranged in an open or semi-open manner. Because the electrical components and piping joints are not effectively isolated, and the overall structure lacks sufficient sealing, environmental condensation easily forms on the component surfaces. Furthermore, if leaks occur at the piping joints, liquid can easily come into contact with the electrical components. These conditions can lead to short circuits, corrosion, and other failures in the electrical components, severely impacting the converter's operational stability and lifespan. Therefore, there is an urgent need to design a string converter bracket to address the reliability issues of the electrical components caused by structural layout defects. Utility Model Content
