Abstract
The 2P DC 1 500 V ACB disconnetctor is suitable for photovoltaic and energy storage systems.This type of product has a cost advantage over older products.The main design improvement points of the product are:Increase the opening distance by modifying the linkage of the mechanism;Passing the critical current test through the main arc contact and narrow gap arc extinguishing technology;Special arc extinguishing and insulation technology are designed through simulation of electric and magnetic fields to ensure reliable arc extinguishing through electrical life testing.After experimental verification,the new 2P DC 1 500 V ACB disconnetctor meets the standard requirements.
