Pole Mounted High Voltage Reactive Power Compensation Device
 
Pole Mounted High Voltage Reactive Power Compensation Device
Application and Features
   The device is mainly connected to 6kV, 10kV AC power frequency system, according to the network voltage and reactive power operating parameters , achieve real-time automated capacitor switching to improve power factor, reduce line losses to improve the quality of power supply voltage.
TBBZ1 is used for 10kV lines, mainly constituted by vacuum circuit breakers, capacitors, controllers, surge arresters, current transformers, voltage transformer, mounting brackets and other components. Current signal sample using the fun-type current transformer.
TBBZ2 is used for 10kV substation bus ,outdoor pole installation, mainly by vacuum circuit breakers, capacitors, controllers, surge arresters, mounting brackets and other components. Input analog current signal with substation and the voltage.
TBBZ3 is used for for the 10kV line, pole installation, the difference between its structure and TBBZ1 was replaced vacuum contactor with vacuum circuit breaker, and assembly of all components used in an outdoor pole box shell.
Vacuum circuit breakers with A, C phase current transformer, which can measure compensation current of capacitor circuit, and is used as over current protection device, controller with vacuum switch for automatic and manual switching of switching. Control power supply for external 220V AC power (substations), line poles installed for the control transformer.
Auto-switching principle: the control voltage is within the scope of eligible cases, according to the demand for reactive power to control the capacitor switching. In the absence of current signals, can control with voltage, time, voltage.
Capacitor discharge device must be equipped if without the discharge resistance.
