■ Product profile
The intelligent vacuum circuit breaker is used in three-phase power system with AC 50HZ and rated voltage 10-12KV.It is be used for closing and opening load current.It has the functions of overload and short circuit protection,quick-break protection,timing,time limit,&delay protection and automatic reclosing.It can also be equipped with arresters or disconnecting switch(that is combination of circuit breakers and disconnecting switch)based on users'needs.The intelligent high voltage vacuum circuit breaker has its own power supply,which can be operated remotely.It has CT and PT interfaces to meet the requirements of telemetering.It also can form a prepaid metering box with switch by heighten the cabinet body and install voltage and current transformers at the bottom.The vacuum circuit breaker can also be operated by permanent magnet operating mechanism to realize manual closing.Because the permanent magnet operating mechanism provides the holding power by the permanent magnet,which keeps the switch in the open and close position,the number of mechanical parts is few and the mechanical transmission chain is short,so that greatly improving the reliability and mechanical life of the switch.

■ Product features
The circuit breaker consists of operating mechanism,conductive circuit,insulation system,sealing parts and shell.The whole structure is three-phase common box type.The conductive circuit type is composed of conductive rod with inlet and outlet wires,conductive plate at static and dynamic ends,conductive clamp and vacuum interrupter.External insulation is mainly realized by silicone rubber material,which has strong anti-fouling ability.Internal insulation is composite insulation.The circuit breaker is operated by an operating mechanism.The mechanical or switching spring drives the three-phase spindle of the circuit breaker to rotate,and pulls the insulating lever and the crank arm at the same time,so that the dynamic and static contacts of the vacuum interrupter are opened or closed,and the circuit breaker is in the opening or closing status.
