TBB High Voltage Parallel Capacitor Device
Product description
The TBB series high-voltage shunt capacitor device (hereinafter referred to as the device) is suitable for AC 50HZ, three-phase 10kV power series, used to improve the power factor and adjust the network voltage, thereby increasing the active output of the power supply equipment and reducing the line loss. This device is indoor (outdoor) type.
Model and its meaning
① Device code
②Parallel capacitor device
③The rated voltage of the device (kV)
④The rated capacity of the device (kvar)
⑤Rated capacity of a single capacitor (kvar)
⑥Capacitor bank wiring and protection mode:
AC-single star voltage differential protection
AK-single star open triangle protection
BL-Double star type unbalanced current protection
Main technical data
• The rated working voltage is 10kV, and it can run for a long time under 1.1 times the rated voltage.
• When the root mean square value does not exceed 1.3Un, the device can operate continuously under rated frequency, rated sinusoidal voltage and current generated by no transition state.
• The device is equipped with overcurrent, overvoltage, and undervoltage protections for system failures.
• The device protects the internal fault of the capacitor. In addition to a single fuse protection, different relay protections are also provided according to the main wiring form. •The design and processing of the device conform to GB50227-1995 "Design Specification for Shunt Capacitor Device" and JB711-1993 "High Voltage Shunt Capacitor Device".

The typical primary circuit plan of this device is shown in Figure 1, where the grounding switch is installed according to user requirements. When installing, put it in the discharge cabinet and change the depth of the cabinet to 1200mm.
Installation dimension drawing
•6-Pre-embedded 10# channel steel and hooks with the opening downwards;
• 4 pre-embedded steel plates and hooks;
•Concrete mirror;
• Embedded steel plates and hooks;
•The embedded steel plates and hooks are evenly distributed on the circumference.
Note:
• This drawing reflects the relationship of the basic dimensions and should be designed according to the actual situation
And construction O
• All embedded parts must be a little higher than the ground for welding.
• Design according to different welding and wiring methods.
