Low Voltage Reactive Power Compensation

Low voltage reactive power compensation The ZRTBBDL device mainly consists of intelligent filtering compensation measurement and control instrument, molded case circuit breaker, current transformer, measuring instrument, lightning arrester, fast fuse (fuse impactor), series iron core reactor (with temperature probe), dry parallel capacitor, thyristor switching switch, fan temperature control device, digital instrument, signal light, complete cabinet and copper bar accessories, etc.

1. During the operation of the compensation device or in the event of its own failure, the device can ensure that it does not have adverse effects on the system, related power equipment, and surrounding environment.

2. High reliability can achieve basic maintenance free operation, significantly reducing maintenance and repair costs.

Wide adjustment range.

3. Small footprint, easy installation, indoor installation, natural cooling.

4. Install a fan temperature control device to forcibly exhaust and cool down if the temperature exceeds 35 ° C.

1. Manual and automatic capacitor switching function

This device can operate in manual mode without capacity adjustment, and is manually controlled by the control panel. The operation status of the capacitor bank can be viewed through the LCD screen, and manual closing and opening can be performed. In automatic mode, a real-time operating condition control strategy can be developed based on the real-time monitoring of load operation, which has the characteristic of high compensation accuracy.

2. Reactive Power Compensation Control

①According to the current operating mode of the load and real-time monitoring data, automatically switch the capacitor bank, control the power factor within a reasonable range, and control the system voltage within the allowable range to achieve maximum voltage optimization.

②When the 0.4kV bus is powered off, the capacitor can be automatically shut down, and after a power outage, the capacitor bank can be automatically put into operation as needed.

③When there is a fault or abnormal voltage in the power system, the capacitor bank can be locked.

3. Protection functions

①Real time monitoring of the operation of capacitor banks in the busbar, and equipped with protection and alarm functions such as overvoltage, undervoltage, and harmonic protection for the busbar.

②The fixed values of each parameter can be modified and viewed on the displayed screen.

The protection device configured with ZRTBBDL can achieve the following protection:

1) Overvoltage protection

2) Low voltage protection

3) Fuse protection

4) Harmonic over limit protection
