● Thanks to the isolated switch, it has obvious break point. Isolated switch, vacuum load break switch and enclosure door have interlocking device which can prevent faulty operation.
● Vacuum interrupter uses the contacts with special structure and material, its chopping current is low and just about 3A,so the operating overvoltage is very low.
● The vacuum interrupter of CKFZ vacuum load break switch is sealed in the insulated parts. It can enhance the performance of dustproof, moisture-proof and insulated and prevent the vacuum interrupter from the mechanical damage.
● The connection between vacuum interrupter and upper disconnected switch is bolt and disc spring compression-fitting connection. It can increase creepage distance of phase-to-phase insulated panel and decrease internal resistance of vacuum load break switch, and then avoid copper foil breakage caused by metal fatigue which comes from repeated twisting of flexible connection, so enhancing its electrical performance.
● Its H-type vacuum load break switch with strong breaking capacity can break 20kA short-circuit current.
● CKFZ and fuse can compose to switch-fuse combination which can break short-circuit current 31.5kA.
● It can combine with CKVB circuit breaker with right lateral operating mechanism and use for power distribution projects with different designs.
● Its structure of functional modules provide different options for functional combination and installation.
● Disconnector and earthing switch are linked together. Their time difference between closing and opening can meet the requirement of electric safety operating rules.
● The interlocking device which prevent faulty operation is equipped inside of operating panel. It can ensure the earthing switch, disconnector and vacuum load break switch to be operated by safety operating rules.
● The spring stored-energy operating mechanism of vacuum load break switch can ensure the switch opening/closing speed meet the technical requirement and not relevant with the strength of the operating power.
● In order to meet the different requirement of the users, it can be equipped with shunt release, lose-voltage release, or overcurrent release.
● In the process of closing/opening, the closing/opening operation of electric operating mechanism won’t be affected by power interruption.
● If vacuum load break switch is equipped with electric operating mechanism, its operating power supply can choose DC power supply or AC power supply.
● Thanks to the new design of enclosure door with interlocking device, its structure is very simple and reliable, also it is very convenient for installation and debugging.
