Description

Transition connector for connecting aluminum alloy photovoltaic cables

Technical Field

The utility model relates to the technical field of cables, particularly, relate to an aluminum alloy is transition connector for photovoltaic cable junction.

Background

The cable is widely applied to the economic society, and the conductor of the cable generally adopts a copper conductor in China. And low-voltage electrical appliances, switches, circuit breakers and the like which are directly connected with the cable are designed according to the copper core cable. Between the aluminum alloy conductor of the cable and the copper contact of the low-voltage apparatus, there is an electrode potential difference due to the material itself, and an electrochemical reaction occurs under the action of oxygen and moisture in the air. Corrosion occurs at this location and the contact resistance increases. The more resistance increases, the more heat is generated; the higher the temperature, the higher the resistance and the faster the electrochemical reaction. Finally, electric sparks are generated at the contact part or the contact part is burnt due to high temperature, so that the conductor of the aluminum alloy cable is broken, and an electricity utilization safety accident occurs.

An effective solution to the problems in the related art has not been proposed yet.
