AI Technical Summary
Existing low-voltage electrical switches have insufficient withstand voltage and arc extinguishing capabilities, which cannot meet the requirements of AC1800V or DC2000V systems, and there are safety and stability issues in high-voltage systems.
An AC/DC arc extinguishing device was designed, comprising first and second arc extinguishing chambers, which are separated by insulating partitions, connected by arc guiding components, and the arc extinguishing plates are arranged in a cross pattern to increase the capacity of the arc extinguishing chambers. The design of the air inlet and exhaust port enables the separate pressure and rapid extinguishing of the electric arc.
By increasing the number of arc-extinguishing plates within a limited space, the arc-extinguishing capacity is improved, the electrical life is extended, the usage requirements of high-voltage systems are met, and convenient installation and maintenance are provided.
