          QY-PDT-03 Low voltage reactive power
          Product Detailed:


          Picture is for reference only
          1Use
            QY-PDT-03 low voltage reactive power compensation cabinet for low-voltage power grid reactive power compensation to improve power factor, reduce line losses and improve power quality. The low voltage reactive power compensation cabinet intelligent reactive power controller as the core, capacitance type contact as capacitor bank switching devices, automatically switched capacitor network power factor, to ensure that the grid always has a high power factor.QY-PDT-03 low pressure non reactive compensation cabinet of compensation components as capacitors, but can be based on each phase of the load with like conduct sub congenial cutQY-PDT-03 low pressure non reactive compensation cabinet of compensation elements by the capacitor and electric anti-control phase series composition has a harmonic suppression function can be used for the higher harmonics of the occasion.

          3.3.7 Rated voltage withstand voltage: 2.5 kV

          4.Major component

          4.1 Control Box

          The cabinet quality cold-rolled steel, the formation of the outer surface spray treatment, anti-corrosion ability; internal frame is made of galvanized steel sheet aluminum zinc steel plate to ensure good electrical conductivity and corrosion resistance.

          The left panel: a main switch, a main protective device circuit breaker, a power outlet, a key selector switch.

          Right panel: a variety of current / voltage measurement terminals, used for the measurement. The current measurement points are equipped 24mmU type short road 

          and bridge connection. 7:00 aviation plug is used to connect the halogen box. Two handles used to simplify transportation.

          Front panel: schematic of the power supply and components, you can see the various parts of the measurement point. Have a "POWER ON" indicator light, a dimming control button, five control selector switch, the NR6 reactive power compensation controller, three green lights. An emergency stop button switch.

          On the panel: device warning lights in a control cabinet.

          The inside of the case: by the circuit breaker, AC contactor, control transformers, current transformers, capacitors, inductors, SCR composite switch and other components.

          4.2 operation box

          Operating box for aluminum structures, the three Halogen (each a power of 500W), the two cooling fans, a thermostat is used to temperature monitoring, the measurement range is 0-60 ° C.

          5Major works

          Through the action of reactive power compensation controller cabinet installed automatically, automatic control cabinet shunt capacitor banks and reactance group inputs and the removal of reactive power consumption is kept at the minimum state, thereby improving the quality of the grid voltage, reduce transmissionsystem and transformer losses. Also switching shunt capacitor banks and reactors group selector switch for manual control.
