JKF8 series intelligent low voltage reactive power compensation controller

Power supply, reactive power compensation controller

JKF8 series intelligent low-voltage reactive power compensation controller is matched with low-voltage parallel capacitive screen device. It is suitable for power distribution system with rated voltage of 380V, AC and 50Hz. It controls automatic switching of parallel capacitors to improve voltage quality and reduce power loss.
The product passed the type test of the quality inspection and testing center of the power industry reactive power compensation device in one time, and the main performance indicators reached the domestic advanced level. With fully automatic mode, "fool" design is one of the best cost-effective products for domestic reactive power compensation controllers.
Features:
1.1 Adopt reactive power and power factor composite control to ensure reliable input at low load and avoid switching oscillation.
1.2 Real-time display of network conditions, including power factor, voltage, current, active power, reactive power and other five parameters.
1.3 Automatically identify the polarity of the sampling signal, no polarity is wrong.
1.4 When the grid voltage is lower than 300V or exceeds the set value, the capacitor bank that has been put into the stage is automatically and quickly (5 seconds), and
The voltage value is displayed.
1.5 When the secondary signal of the current transformer is less than 150mA, the input of the capacitor is blocked, and the automatic and fast (5 seconds) step by step
In addition to the capacitor bank that has been put into use.
1.6 The same group of capacitors cut and lock the lock time is 3 minutes (capacitor discharge time).
1.7 There is a loop self-test function, which is convenient for the capacitor screen factory test.
1.8 Manual operation and automatic operation mode switching function.
Selection:
a. JKF8 series controller switching capacitor circuit number: 6, 12, the number of circuits can be set.
b. Products that exceed the conditions of use and the main technical parameters can be ordered by negotiation.
Conforms to the standard: JB/T 9663-2013; DL/T 597-1996.
