Description

Technical Field

[0001] This utility model relates to the field of microgrid technology, specifically to a control device for microgrids. Background Technology

[0002] A microgrid is a small-scale power generation and distribution system composed of distributed power sources (such as solar, wind, and natural gas combined cooling, heating, and power systems), energy storage devices, energy conversion devices, electrical loads, monitoring and protection devices, etc. It can achieve self-control, protection and management, and can operate either connected to the external power grid or independently (islanding mode), possessing complete power generation and distribution functions.

[0003] Inverters are crucial control components in microgrid power generation systems, converting direct current (DC) energy into fixed-frequency, fixed-voltage or frequency- and voltage-regulated alternating current (AC). In practical applications, the inverter's input needs to be connected to the DC output of the photovoltaic panels for energy conversion. Since inverters in microgrid power generation systems are used outdoors for extended periods, the structural strength of their power connectors is easily affected. Poor contact at the connectors can lead to increased contact resistance, causing current fluctuations and impacting the inverter's output stability, indicating room for technological improvement.

[0012] Furthermore, several heat dissipation fins are evenly distributed on the outer side of the device body.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] An outer sheath is added at the connection between the connecting wire and the device body, and fixed to the outside of the device body by a fixing plate.
