Abstract

The invention discloses a lightning-proof electric control device of a photovoltaic power generation system, which is arranged in the photovoltaic power generation system and comprises lightning arresters, a special grounding wire, lightning-proof devices and a surge protector. The lightning arresters are arranged on non-conductive roofs of a photovoltaic battery assembly support, a controller and an inverter; the special grounding wire is used for connecting a metal device in the lightning-proof electric control device with a grounding main line; the lightning-proof devices are arranged in asolar battery square matrix connection box, the controller and the inverter; and the surge protector is arranged at an alternating current output end. In the embodiment of the invention, the lightning-proof electric control device of the photovoltaic power generation system avoids influencing normal work due to the damage of the photovoltaic power generation system under the thunder and lightningfunction through equipment including the lightning arresters, the lightning-proof device and the like arranged in the photovoltaic power generation system, so as to achieve the aim of improving the work stability of the photovoltaic power generation system.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a lightning protection control device for a photovoltaic power generation system. Background technique [0002] Photovoltaic power generation is a power generation technology that converts solar energy into electrical energy through crystalline silicon semiconductor materials. Crystalline silicon semiconductor materials are composed of PN junctions. Under normal operating conditions, PN junctions can withstand high voltage impacts including electrostatic induction. However, it is very vulnerable to damage when working under high electric field conditions such as lightning. [0003] Photovoltaic power generation system is composed of photovoltaic cell array, battery pack, charge and discharge controller, inverter, AC power distribution cabinet and other equipment. The technology using photovoltaic power generation system as power source is widely used in ur...
