About
Draw-out (withdrawable) vacuum circuit breaker type EvoPact HVX 12 Embedded Pole for switchgear, brand Hetman Electric. New draw-out version vacuum circuit breaker type HVX 12 Embedded Pole designed by Schneider Electric specialists for replacement other vacuum circuits breakers in its class (chassis truck type VCB).
Standard type:
- HVX 12 Embedded Pole is a range of vacuum circuit breakers designed for panel builders to connect industry and utility substations to the power grid;
- it enables the Panel Builder to design switchgear solutions with fixed type or withdrawable type of circuit breaker with enhanced safety features, full control from a separate room and with the following technical characteristics:
- rated voltage 12 kV.
- rated short circuit breaking current 25 kA/31.5 kA/40kA/50 kA.
- rated short time withstand current 25 kA/31.5 kA/40kA/50 kA.
- rated duration of short circuit 3s.
- rated normal current 630 A/1250A/1600 A/2000 A/2500 A/3150 A/4000 A* (*forced cooling).
- HVX 12 Embedded Pole vacuum circuit-breakers designed for switching electrical circuits in normal and emergency modes in three-phase alternating current networks of 50 (60) Hz frequency and 12 kV rated voltage for ungrounded or partially grounded neutral systems;
- HVX 12 Embedded Pole vacuum circuit-breakers are used in newly designed complete switchgears as well as for reconstruction/retrofit of switchgear cubicles in use;
- HVX 12 Embedded Pole vacuum circuit breaker is equipped with a motor-spring drive, which is more reliable, has easy access for maintenance, which makes it possible to quickly and easily replace units that have worked out their mechanical life. The motor-spring drive is universal for all series of HVX 12 Embedded Pole circuit breakers;
- this design provides convenience for operating personnel, a decrease in the number of elements of the mechanism compared to the previous generation circuit breakers, which improves its reliability.
Drive-operated type:
- the circuit breaker of HVX 12 Embedded Pole equipped with driver-operated (motor-driven chassis truck) device and can realize unattended transformer substation;
- the driver-operated device possesses electric machinery overload protection function and extended functions including hand operation precedence and closing interlock, and operates steadily and reliably.
