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.
Compared with the traditional substation reactive power compensation device, the voltage regulated automatic reactive power compensation device adopts a new technical idea, which breaks through the traditional reactive power compensation mode of grouping switching for capacitors with breaker, vacuum contactor and others. The device does not uses switching capacitor to compensate reactive power, but uses the principle of the capacitive reactive power output by capacitor in reactive power compensation is proportional to the square of its terminal voltage. It changes the terminal voltage of fixed capacitor bank by adjusting the output voltage of the regulator, so as to achieve the purpose of fine reactive power compensation. The product has obtained national patent, the patent No .is ZL201020581802.3.
The high-voltage intelligent reactive power compensation device adopts a national patent technology,which integrates permanent magnet vacuum switch,high-voltage capacitor and intelligent controller(including communication).Compared with the general compensation device,the volume and weight of the device are greatly reduced,and the installation is more convenient.The design field strength and the number of internal components of this capacitor are different from general capacitors,which delay the aging of capacitor raw materials,greatly improve its product performance and prolong its service life
