Description

Technical Field

[0001] The utility model mainly relates to the technical field of photovoltaic power generation equipment, and in particular to a cold shrink tube waterproof component dedicated to an offshore photovoltaic connector. Background Art

[0002] Photovoltaics, or photovoltaic power generation system, is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. The energy of the photovoltaic power generation system comes from inexhaustible solar energy. It is a clean, safe and renewable energy source. The photovoltaic power generation process does not pollute the environment or damage the ecology. Photovoltaic power generation systems are divided into independent photovoltaic systems and grid-connected photovoltaic systems. Photovoltaic power generation systems are composed of solar cell arrays, battery packs, charge and discharge controllers, inverters, photovoltaic connectors, AC distribution cabinets, solar tracking control systems and other equipment.

[0003] Since photovoltaic power generation systems need to be set up outdoors to receive solar radiation, the weather at sea is more severe and seawater is more corrosive. The components of the photovoltaic system will be eroded by seawater and aged by the severe climate. The most important of these is the photovoltaic connector. Once seawater enters the connector, the photovoltaic connector will be affected by leakage or short circuit, resulting in the photovoltaic power generation not being able to work properly. On this basis, a special cold shrink tube waterproof component for offshore photovoltaic connectors is proposed. Utility Model Content
