Description

Concatenation hold frame and be used for photovoltaic energy storage system's combination sideboard Technical Field The utility model belongs to the technical field of industrial and commercial energy storage systems, and relates to a spliced accommodating frame and a combined cabinet for a photovoltaic energy storage system. Background In industrial and commercial energy storage systems, an energy storage all-in-one machine typically integrates STS (static transfer switch), PCS (energy storage converter) and MPPT (maximum power point tracker). These components are integrated into a fixed cabinet to form a highly integrated energy storage system. However, the fixed cabinet design brings certain limitations, especially when expansion or adjustment is required according to actual needs, which is not flexible enough. In the conventional integrated cabinet, the number of input/output interfaces of the STS, the dc-side terminal capacity of the PCS, and the photovoltaic string connection channels of the MPPT are all set based on initial requirements. For example, a typical STS device is only configured with 3 input interfaces, and when a user needs to add a fourth PCS, it is necessary to extend a new installation slot in the cabinet body, and further, to add an STS device, and due to the limitation of the physical space and the electrical structure of the cabinet body, it is impossible to directly extend or insert the new PCS and STS device, and it is generally necessary to additionally deploy the whole cabinet or plug-in power distribution unit, which causes a waste of installation space and an increase in cost. From the manufacturing end point of view, since the configuration requirements of different customer scenarios on STS, PCS and MPPT are significantly different, vendors need to develop custom cabinet structures for each configuration combination, which undoubtedly increases complexity and production cost in the manufacturing process. In addition, the installation compatibility of the customized cabinet body is poor, if the later-period requirement of a customer is changed (such as the new photovoltaic group string needs to be expanded with MPPT equipment), the original cabinet cannot adapt to the new configuration through simple transformation, and manufacturers have to redesign and replace the whole cabinet. Disclosure of utility model The utility model aims to solve the problems in the prior art and provides a spliced accommodating frame and a combined cabinet for a photovoltaic energy storage system. The accommodating frame comprises a frame body module, wherein an accommodating cavity for accommodating a functional module is formed in the frame body module, a first connecting part is formed in the top of the frame body module, a second connecting part is formed in the bottom of the frame body module, the first connecting part and the second connecting part can form a complementary inserting structure, and one of the first connecting part and the second connecting part of the frame body module can be inserted into the other of the first connecting part and the second connecting part of the other frame body module, so that the frame body module can be detachably connected with the other frame body module.
