The main functions of the product
1.Harmonic suppression function: effectively suppress high-order harmonics and inrush current, and reject harmonics from entering the capacitor device. It can eliminate the influence of higher harmonics on the capacitor, protect the circuit and capacitor from overload, prevent the capacitor from overheating, aging of insulating medium, decline of self-healing performance and decrease of service life.
2.Synchronous switching function: cooperating with special controller, it has fast response time, can realize dynamic tracking, and accurately switch when the current and voltage are zero, and is less affected by harmonics.
3.split-phase compensation function: split-phase compensation products, each phase capacitor can be switched separately, improve the accuracy of reactive power compensation, so that the three-phase reactive power imbalance can be well compensated.
4.Measurement function: measurement of distribution voltage, current, reactive power and power factor, automatic measurement and correction of CT phase and transformation ratio; Measurement of three-phase current and internal temperature of each capacitor.
5.Protection function: quick circuit current switching and overcurrent protection; Capacitor overvoltage and undervoltage protection; Over-temperature, open-phase and three-phase unbalance protection of capacitor. When the temperature of capacitor exceeds 65 degrees, the whole capacitor will be returned for protection, which will improve the service life and ensure the safe operation of the system.
6.Signal function: capacitor switching state, over-under-compensation state and over-under-voltage state signal: protection action type and self-diagnosis fault type signal.
7.Communication function: RS-485 communication connection is adopted between the capacitor and the controller, which is convenient for uploading a large number of sampling data and exchanging information with the peripheral monitoring terminal to form the system work.
8.Intelligent network control: it can automatically detect and track the change of reactive power of the system and automatically switch capacitor banks. Capacitors with the same capacity are switched according to the principle of cycle, and capacitors with different capacities are switched according to the principle of adaptive compensation. Capacitors are cast first, retreated first, retreated first and cast first; The capacitor with low operating temperature is switched on first, and the capacitor with high operating temperature is switched off first; When the compensation condition is constant, the capacitor is switched on and off periodically every period of time to avoid a single capacitor being put into operation for a long time.
9.Fault self-diagnosis function: the intelligent capacitor control element can self-diagnose the operation parameters of each phase of the body. Once the self-test fault occurs, the whole machine will respond quickly and quit running.
