What are the characteristics of intelligent power capacitor?

1. The intelligent power capacitor is easy to maintain: the nixie tube shows the type of protection action, including over-voltage, under voltage, over current, over temperature, three-phase imbalance, etc.; the intelligent low-voltage power capacitor has the self diagnosis function, which can reflect the switch, capacitor, intelligent module, network communication and other faults on the display screen, which is conducive to on-site fault finding.

2. Zero crossing switching: intelligent thyristor composite start circuit is adopted to realize equal voltage input, zero current switching, switching without inrush current impact, no switching over-voltage, no arc reignition, which greatly improves the equipment's resistance to voltage, current impact and low energy consumption.

3. Intelligent network: when multiple intelligent low-voltage power capacitors are used in the network, a network is automatically generated, in which one with a very small address code is the host and the rest is the slave, forming the low-voltage reactive power automatic control system; if individual slave fails, the automatic exit will not affect the rest of the work, if the host fails, it will also exit, and a new host will be generated in the rest of the slave, forming A new system; capacitors with the same capacity are switched according to the principle of cycle switching, and capacitors with different capacities are switched according to the principle of adaptation; 485 communication interface can be connected to the background computer for integrated distribution management.

4、 Remote communication: it can be extended to realize remote control.

5. High reliability: cancel the controller and adopt the decentralized control mode to prevent the whole system from being paralyzed due to the failure of the controller; the intelligent thyristor composite switching switch ensures that there is no inrush current impact, no over-voltage, no arc reignition and the failure rate is extremely low in the process of capacitor switching, which completely solves the problem of frequent damage of contactors and capacitors in the traditional mode.

6. Energy saving and consumption reduction: 90% energy consumption of conventional capacitor cabinet is reduced. By reducing the volume by about 50%, we can save about 50% of land, copper, silver, engineering plastics and other resources, and reduce about 50% of electric loss of conductor, contact and device.

7. Building block structure: the product is standardized and modularized, replacing the traditional controllers, air switches, AC contactors, thyristors, thermal relays and capacitors, and integrating them into a whole. The building block stacking method is adopted when the group cabinet is installed.

8. Simple wiring: multiple capacitor bank cabinets are installed, and the production time is reduced by more than 60% compared with the traditional mode. Meanwhile, 80% of the connecting wires and 80% of the nodes are reduced. The cabinet is simple and can be assembled quickly on the site.

9. Split phase compensation: realize single-phase separate compensation to solve the three-phase load imbalance; separately compensate the phase with large reactive power deficiency to achieve the optimized compensation effect.

Convenient capacity expansion: the product is small in size and simple in wiring. With the increase of power load of consumers, the number of capacitors can be increased at any time, which changes the conventional mode due to the complex wiring and unchanging limitations. It is suitable for the needs of enterprise development and can be invested by stages.

11. Remarkable effect: ensure the system voltage to be stable and qualified; improve the power factor and predict the input capacitor. If the input capacitor is over compensated, it will not be input to avoid fines due to over reactive power; control the reliability to be 100%, increase the active output of the distribution transformer, reduce the capacity increase investment and reduce the loss and energy saving.

12. Temperature protection: equipped with temperature sensor, it can reflect the internal heating of the capacitor under the conditions of over-current, over harmonic, large leakage current and high ambient temperature, so as to realize over temperature protection. After exceeding the set temperature, the capacitor will be automatically cut off and out of operation, so as to achieve the purpose of protecting the equipment.
