Silicon rectifiers for synchronous motor excitation of KGLA(F)11、12 type、GLA、GLF series
Silicon rectifiers for synchronous motorexcitation of KGLA (F) 11, 12 types, GLA, GLF series are suitable for DC excitation power supply for large andmedium type synchronous motor of drag no-load or light load start. It can be appliedwith synchronous motor with capacity range of 220-6300 kW.
KGLF ‖typeproduct is a equipment with full voltage or step-downstart and constant excitation, which is mainly used in excitation power supplyof synchronous motor for drag mining ball mill, metallurgical blower,fertilizer plants joint compressor, HV compressor and circulating compressor,cold storage ammonia compressor, oil field compressor for refinery, aircompressor for oxyhydrogen station, tube mill for cement, large water pumps andetc.
The product of KGLF12 type automaticallyadjusts all the time according to load, primarily as excitation power for synchronousmotor of drag impulse load (such as rolling machine).
Silicon rectifiers forsynchronous motor excitation of KGLA (F) 11, 12 type, GLA, GLF series all adopt three-phase full-controlledbridge type rectification, and are equipped with multi-protective devices of over-current,short circuit, alarm and etc. The products have advanced design, reasonablestructure, safe and reliable operation, it can keep the inherent startcharacteristics for synchronous motor, the products are designed andmanufactured according to the GB12667 Standard.
- Q:The basic requirements of the rectifier
- Increased input power The rectifier / charger should have an initial power requirement of 20% of the rated load and gradually increase the input power to 100% of the rated capacity over a 10 second time interval. In redundant UPS systems, the input power of each rectifier / charger should be delayed by 5 to 300 seconds to reduce the impact on the generator
- Q:Is the rectifier pulse the better?
- The rectifier is a rectifier, which simply converts AC (AC) into a DC (DC) device. It has two main functions: first, the AC (AC) into DC (DC), the filter after the supply of the load, or supply the inverter; second, to the battery to provide charging voltage. Therefore, it also plays the role of a charger.
- Q:Ups filter and rectifier, respectively, what specific role, said on the Internet filter (filter), is a device used to eliminate interference noise, the input or output filtered through the pure DC. Rectifier will exchange into DC, since the filters have been pure DC, followed by a rectifier in turn to DC? Here is more puzzled?
- This filter is simple and economical, widely used by manufacturers in high-power UPS, the suppression of current harmonic components in the range of 5% to 6%, the power grid is more or less affected, if the precision Instrument, it is possible to measure the work of instability, there *, the reading is not allowed to wait for such phenomena.
- Q:Does the car charge a battery in its own (12V) does not also need a rectifier? To their own spark plug ignition is not "rectification" to ten thousand V? So, in the generator and then a head, rectified to 48V not work? Ask the teacher. Does the car charge a battery in its own (12V) does not also need a rectifier? To its own spark plug ignition is not "rectification" ...
- First 12 volts AC into 48 volts AC, which is easier. And then the rectifier will be 48 volts AC into DC. As for the power, I believe the user can master. Because even a 12-volt power supply, there is also a power problem.
- Q:Buy back the electronic ballast today, want to replace the original gas discharge UV lamp driver, buy back, I found that the electronic ballast has four output lines, but our UV lamp only two wiring. Ask the supplier, they say two lines are inductance ballast,
- Fluorescent tube electronic ballast output is four lines, the wiring diagram attached to the ballast shell, the corresponding two groups were connected to each end of the tube.
- Q:Can the rectifier change the voltage?
- Day off the light of the lighting voltage of more than 400 V, 220V how to start it, in fact, rely on the starter this thing, by the starter to produce a self-inductance electromotive force to light the lamp.
- Q:What is the difference between rectifiers and regulators?
- Regulator: a power supply circuit or power supply device that can automatically adjust the output voltage. Its function is to stabilize the power supply voltage required by the large or unbalanced electrical equipment and stabilize it within the set value range.
- Q:Differences between electronic transformers and electronic ballasts
- Electronic transformer and electronic ballast in front of the self-oscillation circuit is basically the same, but behind the output of the circuit is different from the electronic ballast self-oscillation after the high-frequency voltage connected to an inductor, used to store light fluorescent, Transformer shock after the high-frequency voltage connected to a high-frequency transformer, used to 300V or so high-frequency voltage into 12V or so high-frequency AC, and then used to light 12v halogen bulb.
- Q:Solid state relays are different from rectifiers
- The rectifier is a device fabricated using a semiconductor element. Rectifier as the name suggests is the use of semiconductor characteristics in the AC circuit can be alternating current into a DC current device
- Q:In the motorcycle above the full-wave and half-wave regulator rectifier can be used interchangeably? Will not burn the electronic device? Charge to the battery whether the impact?
- The full-wave rectification before and after the waveform and half-wave rectifier is different from the full-wave rectifier in the use of two half-wave, which improves the efficiency of the rectifier, and the entire current is easy to smooth. Therefore, in the rectifier widely used full-wave rectifier, half-wave rectifier is only used in less demanding circuits.
