Hollow reactor performance standards GB10229-88 "reactor" DL462-92 "ordering technology with high-voltage capacitor series reactor" JB5346-1998 "series reactor" IEC289-88 "reactor" JISC4801-1997 "pressure and special high-voltage shunt Capacitor Series Reactor "works: the main route back down high voltage electricity H.APF ++ integrated active filter and reactive compensation devices connected reactors, circuit breakers, DC energy storage capacitors, IGBT module based on the converter, buffer and absorption circuit. By a three-phase IGBT modules connected in parallel to the parallel converter power line via a series Buck reactor. Load current through the main circuit CT is collected H.APF ++ control system relay, isolated by real-time detection circuit load current reactive and harmonic components, application of large-capacity high-speed data processor DSP chip, PWM latest IGBT technology control trigger, by adjusting the three-phase inverter AC side output voltage phase and amplitude, to produce simulated load harmonic current equal and opposite to the direction of harmonic current injected into the grid, and load harmonic currents cancel each other to achieve harmonic filtering function. If H.APF ++ is not only functional requirements but also at the same time filtering reactive power compensation function, H.APF ++ superimposed on a sinusoidal current waveform of the output of the harmonic current, as opposed to reactive load current phase, size equal dc3.3v relay, the sinusoidal current controlled phase and magnitude, to inductive or capacitive reactive bidirectional continuous compensation. High pressure filter compensation parallel sets of equipment Product details: The main purpose and scope of high voltage shunt filter compensation package (hereinafter referred to as the device) is mainly used for frequency 6kV, 10kV, 20KV, 35kV three-phase power system for harmonic suppression, adjustment, balance the grid voltage tx24v relay, improve power factor, reduce losses and improve power quality. Features 1, means long-term operation at 1.1 times the rated voltage of the steady-state over-voltage: 2, the device can not root-mean-square value of more than 1.3 times the rated current of the capacitor bank overcurrent continuous operation; 3, the device uses no heavy breakdown The high-voltage circuit breakers, and equipped with zinc oxide surge arresters to limit capacitor switching overvoltage generated during operation; 4,6kV, 10kV means chosen vacuum load switch, vacuum circuit breaker or SF6 circuit breakers to make filter compensation branch The switching switch. For small capacity of the capacitor bank relay 24v10a, and the need to packet switching using vacuum contactors, the large capacity capacitor bank should vacuum breaker or SF6-type switch; 5, the device selection dry hollow reactor or dry reactor core, to limit inrush current, high harmonics, improve network voltage waveform. 6, means the choice of FD type discharge coil may, within 5s the residual voltage from the rated voltage of the capacitor bank peak to 0.1 times the rated voltage or less; 7, according to the system and the user's needs, the device can be local control or the main control room , centralized control or automatic control mode; 8, means the use of a single capacitor fuse protection based protection, open delta voltage, voltage differential, neutral current imbalance as the backup protection, in addition to device also features overcurrent, overvoltage , voltage protection. Protection can also use these better performance of computer protection monitoring device, in order to achieve the capacitor protection requirements.
