II. Working principle
The work principle of Farady regulating type capacitors is that: Connect all the capacitors to the electric network with voltage regulator ,the output reactive power will be adjust by voltage regulator, refer to the capacitor output power formula.The set of equipment is made up by following equipments:1. Load break switch2. Insolating switch3. Voltage regulator4. Intelligent controller5. Capacitors6. Lighting arrester7. Metering CT, PT Assuming that the nominal capacitance of the capacitor is Qn , the connected voltage regulator regulation range is 50%Un-100%Un, so refer to the formula ,voltage regulator is designed with 9 taps tap changer to change the network voltage, the output reactive power in every regulator position.

The traditional way of reactive power compensation is changing the quantity of capacitors to adjust output reactive power, change method is usually switch or contactor, will result in following hazards:1. The conventional reactive power compensation method has a large compensation capacity and the adjustment is not flexible, it will lead to the compensation is not suitable , often appear over and not enough.2. The capacitor switching can cause over-voltage and inrush current, and it will seriously affect and reduce the service life of the switch.3. When the capacitor is switched on, as the capacitor will charged and discharged, when it need to switch on again, which affects the speed of the switching. According to the above problems, o company developed the FLYK type reactive power compensation device, has the following advantages:
(1). Energy conservation: Farady voltage regulating type capacitors will change the output reactive power by regulating voltage on capacitors, so that the reactive power can be adjusted smoothly. Comparing with other method, it can ensure the capacitors in best condition, the energy saving effect is much better(2). Low cost:If the old power transformer substation need to reform, only need to add a voltage regulator between the circuit breaker and capacitors, the original circuit breakers, reactors, capacitors can be reuse, greatly reduce the cost of transformation(3). Maintance Free:When traditional circuit breaker and contactor switching, switching devices and capacitors often damaged because of the above problems, result in high maintenance costs, using Farady devices, automatic control reactive power output, there is no potential risks of other equipments, greatly reducing maintenance and staff costs in power transformer substationPacking & Delivery
IV. Equipment application
1.Compact type
This type of devices install all electrical components in the cabinet that required, cabinet made of galvanized steel or stainless steel, the voltage is 3 5kV and below, capacitance below 4000kvar will use such structure. This type of structure is orderly, the installation and the maintenance are convenient, the occupied area is small, and the structure is suitable for the interior installation of a new power transformer substation.
2 . Outdoor type
This install type with a fence around the equipment enclosure ,occupy an area of slightly larger, but the maintenance is very convenient, for in indoor and outdoor use, especially suitable for old power transformer reforming.Our Company
