Product Overview
TBBZ high-voltage reactive power automatic compensation device is designed for reactive power compensation in high-voltage distribution systems. It is commonly used for high-voltage reactive power compensation and industrial and utility distribution systems, with the final selection based on rated data, drawings, and site conditions.
electrical contractors, industrial plant engineers, EPC companies, maintenance teams, and project distributors can request configuration review for high voltage power compensation device. Please send system voltage, compensation or filtering capacity, control logic, monitoring requirements, cabinet quantity, and wiring diagram, quantity, destination, and any project standard requirements for quotation.

Technical Specification
Review the TBBZ compensation protection, controller communication, reactor selection, rated voltage, rated frequency, capacity range, and group arrangement before quotation.
| Item | Unit | Parameter |
|---|---|---|
| Single capacitor protection | Spray-type fuse protection; each group is equipped with a lightning arrester for operating overvoltage and lightning-strike protection. | |
| Controller and communication | Large-screen LCD controller displays system voltage, current, and power factor in real time; RS232 / RS485 standard communication interface supports four remote-control functions. | |
| Reactor configuration | Each group can be configured with a reactor to suppress closing inrush current or harmonic amplification. | |
| Rated voltage | kV | 6-10 |
| Rated frequency | Hz | 50 |
| Rated capacity | kvar | 100-10000 |
| Number of groups | groups | 1-5 |
| Reactor parameter selection | % | 0.1-1 for suppressing closing inrush current; 6 for suppressing harmonics above the 5th order; 12 for suppressing harmonics above the 3rd order. |

Installation Dimensions / Drawing
ForTBBZ, confirm the cabinet outline, ventilation space, wiring path, component arrangement, and control interface drawing. Use the confirmed technical table, project drawing, and site installation plan as the final dimensional reference before ordering or installation.
Applications
TBBZ is mainly selected for high-voltage reactive power compensation and industrial and utility distribution systems. The final application should match the confirmed high voltage power compensation device, rated data, and site installation conditions.
- High-voltage reactive power compensation
- Industrial and utility distribution systems
- Projects requiring power factor and compensation control
Ordering Instructions / Information Required for Quotation
Ordering Instructions / Information Required for Quotation
- Please specify any special requirements for compensation capacity and grouping for the full range of product models.
- Confirm whether a microcomputer monitoring device is required, and state whether the installation type is indoor or outdoor.
- When a reactor is required, provide the harmonic situation, especially the order of the lowest harmonic.
