Description
Technical Field
[0001] The utility model relates to the technical field of lightning protection for photovoltaic power generation systems, in particular to an integrated surge protector. Background Art
[0002] With the deepening of global energy transformation and carbon neutrality goals, the photovoltaic industry has ushered in sustained and rapid development. It is expected that in the next few years, photovoltaic installed capacity will maintain rapid growth, and the photovoltaic industry chain will continue to optimize and upgrade, becoming an important part of the future energy system. Photovoltaics are all installed outdoors. When photovoltaic panels are installed, it is often preferred to install them in high places and in open areas to ensure that they can receive more sunlight; photovoltaic equipment is installed outdoors, and only lightning rods are used to protect it from lightning strikes, but overvoltage will still be generated during the use of photovoltaic equipment. When overvoltage occurs, it will also cause serious losses to photovoltaic equipment and cause damage to it. When a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt in a very short time, thereby avoiding damage to other equipment in the circuit caused by the surge. Installing a surge protector in a photovoltaic power generation system is an effective measure to prevent damage to equipment caused by lightning current and overvoltage, so as to ensure the reliable and stable operation of the photovoltaic power generation system. The surge protectors used in existing photovoltaic power generation systems can only meet the needs of 1500V photovoltaic power generation systems. However, due to their large size, small electrical distance and creepage clearance, the existing surge protector structure cannot meet the needs of 2000V and above photovoltaic power generation systems installed at an altitude of 5000 meters or above.
