HZW 12/630 type outdoor high voltage double power supply automatic switching device is composed of two parts of a high voltage vacuum circuit breaker and intelligent controller
HZW 12/630 type outdoor high voltage double power supply automatic switching device is composed of two parts of a high voltage vacuum circuit breaker and intelligent controller. Applicable to AC 50Hz, rated voltage 12kV, rated current 630A, dual power supply system. When a power supply power failure or undervoltage automatic switching to another normal power supply, reliable guarantee the continuity of electricity. At the same time has the short circuit and transition interlock functions such as protection, effectively avoid the unnecessary power supply shock again when load failure. Power failure occur S in the normal power supply, automatic switching device can complete the standby power supply, to ensure the safety and reliability. Also can choose to switch between two powers according to the needs of load. Particularly suitable for the important places do not allow failure, as important to ensure continuous power supply of the electric control device. As a new generation of new design, perfect in performance, safe and reliable, high degree of automation, wide range of use of the cast from the replace dual power automatic switch products. Products to ensure the complete isolation of two high voltage power supply in the design, the mechanical and electrical interlocking perfect and reliable, so it has very high security and reliability. The product is suitable for power supply reliability and safety requirements of high power electric power users, as a dual power supply system of control and protection devices
Products are widely used in oil fields,mines, metallurgy, chemical industry, railways, communications, machinery and so on 12kV distribution line, industrial and mining enterprises 12kV line.
