[0002] With the rapid development of energy storage technology, energy storage systems are increasingly used in the generation, transmission, distribution and use of power systems. In order to meet the needs of power generation systems such as photovoltaic power generation and wind power generation, energy storage systems usually include converter modules and boost modules.

[0003] In traditional energy storage systems, the energy storage converter (converter module) and the box transformer (boost module) are two independent modules with high manufacturing costs. Since each module is usually large in size, it needs to be transported separately, which has high transportation costs. And during on-site installation, since the converter and boost modules are not integrated into one, electrical connections such as cables need to be made on-site, which makes on-site operation and maintenance installation complicated, installation and debugging integration difficult, and the overall system occupies a large area and is difficult to arrange.

DETAILED DESCRIPTION

[0024] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0025] The features and performance of the present invention are further described in detail below in conjunction with the embodiments. Figure 1 - Figure 5 .

A vacuum load switch 6 is also arranged in the high-voltage chamber 7, and the transformer is connected to the vacuum load switch 6 through a copper bar 8.
