Product Description

Product Introduction
The CJDR low-voltage complete reactive power compensation device is an electromechanical device integrating grid reactive power compensation and operation status monitoring. It is a high-efficiency energy-saving device for improving power grid quality. The device automatically controls the switching of shunt capacitor banks based on the power factor value in the power distribution system, keeping the grid power factor always above 0.95.
Key Features:

• Automatic Compensation: The device automatically adjusts the compensation capacity according to changes in the system's reactive power, achieving optimal compensation results.
• Loss Reduction: Properly configured reactive power compensation devices can reduce line losses by 8% to 15% on average.
• Power Factor Improvement: By automatically switching capacitor banks, the system power factor is maintained above 0.95, reducing reactive losses and improving power supply efficiency.
• Multiple Protections: Equipped with overvoltage, undervoltage, phase loss, harmonic overlimit and other protection functions to ensure long-term stable operation.
• Intelligent Control: Adopts an intelligent controller supporting remote monitoring and automatic adjustment, tracking system reactive power changes in real time.
• Communication Interface: Supports RS485/Modbus communication protocol, enabling data exchange with host computer systems for unattended operation.
• Flexible Switching: Supports multiple switching methods including contactor switching (for stable loads), thyristor switching (for frequent operation), and composite switching (low power consumption, no inrush current).
• Strong Applicability: Suitable for reactive power compensation of continuously operating asynchronous motors and inductive loads, widely used in various industrial and civil power distribution systems.
• Standard Compliance: All technical indicators comply with GB/T 15576 and IEC 61439 standards.
• Operational Track Record: Has been stably operating in major projects such as the high-speed railway project of the Ministry of Railways.
