China GGJ Low Voltage Intelligent Reactive Power Compensation Cabinet - Reliable Suppliers and Factory Solutions for Energy Savings
Model and Definitions
Product Features
Inductive loads in the power grid (generators, chokes, transformers, induction heaters, welding machines, etc.) will produce varying degrees of hysteresis, the so-called inductance. Inductive loads have the characteristic that the direction of the current (such as the forward direction) can be maintained for a period of time when the voltage changes direction. Once this phase difference between current and voltage exists, reactive power will be generated and reflected. In AC grid (50/60Hz), The above process is repeated 50 or 60 times per second, so an obvious solution is to temporarily store and release the inductive power energy (reactive power) directly through capacitors, thereby reducing the reactive power exchange of the power grid.
- The compensation cabinet has strong universal performance. It can be combined with any cabinets at home and abroad, such as MNS, GCK, GGD etc.
- The capacitor compensation combination is diverse and flexible. Y Compensation method, △ Compensation method, and Y+△ Combined compensation method.
- Diversity of communication methods. RS-232/485 Communication interface, wireless data transmission module or GPRS Module implements long-distance communication.
- The control is accurate and safe. It implements voltage zero-crossing triggering, no surge current zero-crossing cutoff when it is put into operation, and no high voltage is generated when it is disconnected.
- Long service life, maintenance-free, service life of more than 100,000 hours.
