{{EN_0} □ Low voltage reactive power automatic compensation deviceDetailed product description：

ZGW() -0.4/□ type low-voltage reactive power compensation device is a low-voltage complete set of equipment designed in accordance with the requirements of the State Grid Construction and the power department, based on the principles of safety, economy, rationality, and reliability. This product is widely used in power distribution systems with a rated frequency of 50Hz, a rated compensation capacity of 30-90kvar, and a rated voltage of 400V. It is used to improve power factor, enhance power supply quality, and reduce energy loss. The XGD-0.4/□ W type low-voltage reactive power compensation device complies with standards such as GB7251.1-1997 "Low Voltage Switchgear and Control Equipment" and VB/T15576-1995 "General Technical Conditions for Low Voltage Reactive Power Static Compensation Devices".

Structural characteristics:
1. Automatically design switching capacitors based on reactive power requirements, using phase separation, grading, and cyclic switching methods, with a maximum of six levels for each item;
2. The controller has a "△+Y" type output, high compensation accuracy, and good effect. The controller can also have distribution monitoring and measurement functions;
3. The switching switch adopts a composite solid-state relay, which has no electric shock zero crossing trigger, no closing surge, no arc generation, fast response speed, and does not generate heat during operation, with a long service life;
4. Adopting a new type of low-voltage self-healing capacitor with internal self discharge function, small size, high reliability, and long lifespan. Power outage control, whose terminal voltage can drop from the peak rated voltage to below 50V within 3 minutes;
5. The device is instantly powered on after a power outage to prevent the capacitor from self inserting;
6. The device can measure the distortion rate of the harmonic voltage at the installation site. When the distortion rate of the harmonic voltage at the installation site exceeds the preset value, the device will sound an alarm;
7. It can be equipped with a remote data communication interface and can achieve remote monitoring and data collection through GPRS module. You can also choose the WDM-1 wireless adapter produced by our company to achieve wireless data reading.
