รายละเอียดสินค้า

The JKW series reactive power automatic compensation controller (referred to as the controller) is a specialized equipment for compensating reactive power in low-voltage distribution systems, designed according to the industry standardJBT9663-2013of the People’s Republic of China and the power industry standardDUT597-1996.Its sampling physical quantity is reactive power, which has the advantages of novel design, multiple functions, good control performance, and high reliability, it is in a leading position among similar products in China and provides a new equipment for distribution automation.

• Adopting AC sampling technology;
• Using fundamental power factor and fundamental reactive power as control physical quantities, high control accuracy, no switching oscillation, and insensitive to harmonics;
• All digital operation of control parameters,easy to use,one step in place, without losing power outage data;
• Adopting automatic optimization control to reduce switching freauency and improve the service life of the system;
• Strong anti-interference ability,able to withstand 2000V interference pulses directly input from the power supply,without crashing or losing data, stable and reliable operation;
• Digital display of power factor,reactive power,voltage,current (primary side), control parameters of the power grid;
• There are two working modes: power factor mode and reactive power control mode,which are convenient for users to install and debug;
• It has the function of judging and displaying over voltage and under voltage, and quickly cutting off the capacitor bank to prevent the capacitor bank from operating under over voltage conditions;
• With optional switching oscillation locking function (users need to indicate when ordering);
• With the optional function of delaying a 200 second delay from the cutting of time to the input time of a single set of capacitors,there is suficient discharge time after the capacitor bank is cut off,reducing the impact on the power grid when the capacitors are put into operation again (users need to specify when ordering);
• The input resistance of the current sampling signal is less than 0.05 ohms and can be directly taken out of the metering circuit;
• There are two compensation modes: power factor and reactive power;
• The user manual provides a large number of troubleshooting methods for easy installation and debugging.
