At present, as a large capacity energy storage component with high reliability and long cycle life, ultracapacitors are the preferred backup power supply for automation terminals and instruments in the power field. Devices with backup power supply can still meet the functional requirements of communication information reporting even when the main power supply fails.
However, because the voltage level of a single ultracapacitor is low, multiple ultracapacitors need to be used in series. In engineering applications, supercapacitors are usually modular and integrated. When they are used in intelligent power distribution terminals, common supercapacitors have the following problems:
1. Capacity is related to volume. Under the same capacity, the thinner the thickness of the module, the higher the height of the module, which requires the installation height space of the product;
2. After the module is packaged, the volume is large, and it generally needs to be fixed to the product body by screw fixation, resulting in multiple production procedures and affecting production efficiency;
3. The positive and negative poles of the power supply of the module are led out through multiple insulated flexible wires, and then connected to the products through wiring terminals, resulting in multiple production procedures and low production efficiency.
In the state Grid version of intelligent distribution terminal and its similar products, such as concentrator and smart electricity meter, mold shell is adopted. This shell has the characteristics of miniaturization and stacked assembly of internal electronic board. Due to the limited structural space, it is impossible to install a large-capacity modular supercapacitor.
