Shunt capacitor bank,TBBZ auto-compensation shunt capacitor bank

Product introduction

The TBBZ-type shunt capacitor bank is mainly composed of TRZ controller, stepped switch, high-voltage shunt capacitor, series reactor, fuse (or internal fuse), zinc oxide arrester, discharge coil, disconnector, post insulator, busbar and fittings, etc.

On the basis of the conventional high voltage shunt capacitor banks, the dedicated vacuum circuit breaker and automatic switching controller are added to the device to realize the automatic switching of capacitor reactive power capacity in groups, and achieve the purpose of on-load capacity regulation. The TBBZ high-voltage shunt capacitor banks uses the reactive power automatic controller to detect the grid voltage and power factor, and through the comprehensive judgment of the system voltage and power factor, it controls the automatic switching of each capacitor bank to balance the system voltage and improve the power factor, so as to reduce line loss, improve power supply quality, and effectively solve the problem of reactive over-compensation and under-compensation.

Product feature

² The dedicated vacuum switch for capacitors has passed the capacitor capacitive switching back-to-back test, which is shock resistant and suitable for frequent switching.

² The automatic compensation has high accuracy and low impact, which can obtain the maximum reactive power compensation effect.

² Each capacitor is equipped with over-current protection and internal fault protection components, which can disconnect the faulty capacitors timely and effectively to ensure the overall safe and reliable operation.

Application field

The TBBZ-type high voltage shunt capacitor banks can be applied to 35kV, 110kV, 220kV, 500kV, 750kV substations for power system and industrial and mining enterprises, it can also be used in 6kV and 10kV voltage level of enterprise distribution power stations as well as newly-built and renovated shunt capacitor devices in all levels of power distribution network.
