The multi-group automatic switching reactive power compensation device is based on the conventional high-voltage parallel capacitor device, which adds a special switching switch and automatic switching controller for the capacitor bank to realize the grouped automatic switching of the capacitor reactive capacity to achieve reactive power compensation,to achieve the purpose of reactive power compensation.
The device is mainly composed of capacitor bank, isolation switch, high-voltage vacuum circuit breaker or high-voltage vacuum contactor, discharge coil, current transformer, reactor, etc.
It is mainly used in 6 ~ 35kV power system to improve the power factor of the system, reduce the loss of transformers and lines, and improve the quality of power supply. The device is widely used in chemical, petroleum, metallurgical, and coal systems to maximize the compensation of reactive power of the system. The controller in the device adopts the "nine-domain zone" control principle and various operating modes to prevent the switching from oscillating. The device also has an RS-485 communication interface, which can realize four remote functions and can be connected with the substation integrated automation system.
(1) The special vacuum switch used for capacitors has passed the
back-to-back test of capacitive switching of capacitors, which is
suitable for frequent switching.
(2) The automatic compensation is divided into two to five
switching channels, with high compensation accuracy and low impact,
which can obtain the maximum reactive power compensation effect.
(3) Controller uses intell6 bit microcontroller, large-screen
character display menu, has a friendly interface, real-time display
operating parameters and fault information; with a RS-485
communication interface, four remote functions, and can be
integrated substation automation interface, Realize the three
aspects of control and management: on-site, background machine and
scheduling.
(4) The controller adopts the "Nine Domains" control principle to
automatically identify various operation modes of transformers and
capacitors in the substation to prevent switching shocks.
(5) Each capacitor is equipped with overcurrent protection and
internal fault protection, which can isolate faulty capacitors in
time and effectively, and has a voice alarm function to ensure the
overall safe and reliable operation.
