Low -voltage dry -type in -line wire electrical antifiers
The frequency converter will generate large harmonics during working. Harmonics are mainly fifth, seventh, eleventh and thirteenth harmonics. The content of harmonics is very high. If the incoming line reactor is not applied, the service life of the frequency converter and other electric devices will be greatly shortened. When the harmonic interference is severe, some devices cannot run normally. After applying the incoming line reactor, the content of harmonics will be significantly reduced, the power factor of the grid will be improved, the safety operation of the frequency converter and other loads will be guaranteed, and it is ensured that other devices will not be interfered by harmonics; application of the outgoing line reactor can inactivate the steepness of the output voltage (switching frequency) of the frequency converter and reduce interference and impact of power elements in the inverter. And this series of reactors can effectively inhibit inrush current in the loop and protect the frequency converter and other elements in the loop from the current surge when switching on the load in an instant.
High voltage dry air core series reactor
After the high-voltage dry-type air-core series reactor is connected in series with the power capacitor, it can effectively suppress the high-order harmonics in the power grid, limit the closing inrush current and operating over-voltage, improve the system power grid waveform, increase the power factor of the power grid, and have a negative impact on power capacitors and other power equipment. It plays a major role in the safe operation of the power system and is an important supporting equipment for the reactive power compensation device of the power system.
High voltage Dryhollow shunt reactor
High-voltage shunt core reactor is connected in parallel in the power system and is especially suitable for long-distance power transmission. Its function is to compensate the distributed capacitance current in the system and ensure that the grid voltage regulation rate is at a certain level.
High voltage dry type air core reactor
High-voltage filter reactors are used in high-voltage filter devices. They are connected in series with filter capacitors and tuned to a certain resonant frequency. They can effectively absorb harmonics of corresponding frequencies in the power grid and improve the system power grid waveform.
The discharge coil is used to connect with high-voltage parallel capacitors in the power system, allowing the remaining charge of the capacitor bank to be quickly discharged after being cut off from the power system. Therefore, installing discharge coils is a necessary technical safety measure for parallel capacitors in substations, which can effectively prevent overvoltage and overcurrent that endanger equipment safety when the capacitor bank is closed again due to the fact that the capacitor still carries charge, and ensure the safety of maintenance personnel. It can be equipped with secondary windings for line monitoring, monitoring, and secondary protection.
Voltage transformer, abbreviated as PT, is an instrument that converts high voltage on the primary side into low voltage on the secondary side based on the principle of electromagnetic induction for measurement.
