High pressure startup cabinet

high voltage startup cabinet is composed of high voltage electromagnetic switch and current limiting fuse power combination, has the characteristics of excellent protection coordination, expand to limit the short circuit fault disaster domain, to ensure the safety of the other parts of the circuit system, the standard decompression starting unit can smooth start-up and operation of high voltage motor and play a protective role. It can make full use of the monitoring, control and protection tasks for the large-scale electrical equipment and the transmission and distribution system of the modern workshops. On the basis of regulations and standards: national standard reference China (CNS 3994 C4132).
