Capacitor, and especially the metallized film capacitor, we've talked about a lot, but for capacitor some must understand the additional function of today and we say,

1, zero crossing switching: the intelligent zero crossing switching circuit and Realization of voltage input, zero current removal and switching useless Liu Chongji. No over-voltage, no arc reignition, greatly improve the equipment of high voltage, impulse current, low power consumption, reduce energy consumption of 80% of the conventional capacitance cabinet.

2 and phase splitting compensation: to achieve single phase compensation respectively, solve the three-phase load imbalance, to reactive power shortfall larger is a separate compensation to the compensation effect of the optimization.

3, energy saving: volume is reduced by about 50%, save land steel, silver materials, engineering plastics stool resources 50% or so, the electrical conductor loss, electric contact loss and devices such as power loss reduced about 50%.

4, temperature protection: equipped with temperature sensor, can reflect the capacitor current, harmonic, leakage flow and environmental temperature is too high, etc. in capacitor internal fever. Over temperature protection,automatic temperature exceeds the set after the removal of the capacitor, out of operation, reach the purpose of protection equipment.

5, intelligent network: multiple intelligent capacitor network, automatic generation of a network.

6, high reliability: eliminating the controller, distributed control mode is used, to prevent due to the malfunction of the controller lead to paralysis of the entire system, intelligent zero crossing switching switch to ensure capacitor switching process without inrush current, no over-voltage, no arc reignition, failure rate is extremely low, completely solve the traditional mode of contactor, capacitance are often solve the problem.

7, the structure of the building blocks: Group cabinet installation adopts building block stacking mode.

8, expansion of convenient: can always increase the number of power capacitor, changed the conventional mode of complex wiring, the limitations of the static, adapt to the enterprise development needs, can be phased investment.

9, the maintenance is convenient with simple man-machine interface, interface display protection action type: overvoltage, undervoltage, over-current, over temperature, three-phase unbalance etc.; intelligent power capacitor with self diagnose function, can display reflect the electronic switches, capacitors, air switch, intellectual can network communication module and fault, is beneficial to the on-site troubleshooting.

10, the effect is remarkable: security system voltage stability qualified, improve power factor, prediction of input capacitor, if the input capacitor over compensation, investment is not, avoid reactive excess and fines; improve distribution transformer active power output, reducing investment in capacity, energy loss.
