Reactive power compensation capacitor counter 
 Capacitance cabinet manufacturer, we provide you with the quoted capacitors, reactive power compensation capacitor cabinets technical support, capacitor cabinets prices, configure counter capacitor, capacitor cabinets evaluation and other related information, you are welcome to buy 
 Some of the power system users frequently use a lot of changes in the load equipment, such as rolling mills, electric arc furnace, frequency converter, intermediate frequency furnace, soft start the load generated by high harmonics into the power grid also will, cause voltage and current distortion use of electric environmental degradation, affecting the normal operation of electrical equipment. capacitive reactive compensation for this device design cabinet resonance offset function, can effectively avoid the high harmonics of the parallel resonant, harmonic filter, and No high current generation, power distribution grid to ensure proper quality. 
 Reactive power compensation capacitor counter functions: energy, capacity increase, regulators, filter 
 1, the reactive power compensation and filtering to reduce the total current, power loss reduction, the energy saving. 
 2, the reactive power compensation capacitor counter-free power compensation, power distribution equipment to increase power supply capacity, the capacity increase. 
 3, the dynamic reactive power compensation, fast response, and real time, no flicker, so that the output voltage stability, the regulator. 
 4, the dynamic reactive power compensation device can filter out the harmonics, eliminate harmonic interference, the filter. 
 Second, the capacitance of the main features of cabinet 
 1, the reactive power compensation capacitors cabinet DSP-based digital signal processing LSI technology, the acquisition parameters for reactive power calculation, the output switching control signal; response speed, real strong, quick to follow the compensation, improve power distribution system power factor and operational stability. 
 2, the reactive power compensation capacitor switching switch cabinet is the use of SCR switching capacitor, magnetic latching relay operation work, no closing inrush current, no heat, low power consumption, simple structure, easy installation, the failure rate low, so that the whole long maintenance-free, and its advanced lead at home. 
 3, the capacitor controller cabinet with a large screen LCD display, sampling, calculation, display the system power factor of each phase, voltage, current, active power, reactive power, voltage total harmonic distortion, current total harmonic distortion, frequency, capacitance output switching status display and alarm information 
 4, no inrush current during switching, no over-voltage operation, no re-ignite the arc, fast dynamic response, up to 6.7-20ms. Capacitor discharge after excision without the need to re-invest, thus frequent switching; user requirements can be a multiple of compensation in place, can also be divided into three-phase compensation for phase compensation. 
 5, the reactive power compensation capacitor cabinets complete protection; a short circuit, overload, undervoltage, phase loss protection; can manually switching controller; the convenient parameter setting; when external exit automatically when a fault running automatically after power transmission recovery operation. 
 6, with excellent performance, self-healing type power capacitor, low loss, long life and little maintenance, low operating costs, together with the discharge resistor, overvoltage, over current protection. 
 7, harmonic source distribution system based on user conditions, tested, calculation, design filtering capacity of the relevant harmonic filter capacitor cabinets and improve power factor.
