Summary

TBBZ series high voltage reactive power automatic compensation device automatically tracks and switches on and off the capacitor bank of the control system according to the power grid and load conditions of 6kV and 10kV power supply buses, so as to automatically track and compensate the reactive power, and the power factor reaches more than 0.9.

Model meaning

For example, tbbz10-1500 (600 + 900) - AK indicates that the voltage is 10kV and the device capacity is 150okvar. It is divided into two groups of automatic switching, one group of 60okvar and the other group of 9ookvar, single star wiring and open delta voltage protection.

Normal service conditions

◇ altitude: no more than 1000m; ◇ ambient temperature: - 25 ~ + 55 ℃:

◇ relative humidity: no more than 85%:

◇ no explosive medium is allowed in the operation site. The surrounding medium shall not contain corrosive and insulating gas and conductive medium. It is not allowed to be filled with water vapor and serious mold.

Product features

◇ the device can operate for a long time under the steady-state overvoltage of 1.1 times the rated working voltage:

◇ the device can operate continuously under the overcurrent with the root mean square value not exceeding 1.3 times the rated current of the capacitor bank:

◇ the device adopts vacuum contactor for switching, which can be operated frequently;

◇ each group of capacitors is equipped with discharge coils, which can reduce the residual voltage below 50V within 5 seconds;

◇ each group of capacitors can be protected by relay or microcomputer protection control unit to realize overcurrent, voltage imbalance, undervoltage and overvoltage protection of the system. When a group of capacitors fails, this group of capacitors can be cut off without affecting the use of other capacitors:

◇ single capacitor is protected by spray type fuse, and each group is equipped with lightning arrester for starting operation overvoltage and lightning overvoltage protection:

◇ large screen LCD controller, real-time display of system voltage, current and power factor; It has RS232 / RS485 standard communication interface and can realize the "four remote" function:

◇ each group can be configured with reactor to suppress closing inrush current or harmonic amplification.
