Silicon rectifiers for synchronous motor excitation of KGLA(F)1112 typeGLAGLF 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: The difference between rectifiers and transformers
Ordinary ballasts and transformers are the same principle, are made using electromagnetic induction principle, but the function is different, one used to limit the current, one is used to change the voltage size.
Q: Where can the rectifier be used?
Rectifier generally exchange into DC, so the place to use DC generally have rectifiers, such as DC motor in front of the inverter inside, and some places are DC transmission, substation which also has a rectifier, low voltage weak electrical control circuit board generally used To 5v DC, the front of the circuit board also has a rectifier. Hope to adopt.
Q: How does the rectifier turn AC into DC?
This control can be accomplished by applying a so-called on-load tap changer for the machine. As a typical case, the on-load tap changer controls the input AC voltage at the primary side of the rectifier transformer, thus enabling the output of the DC value to be controlled within a certain range. Typically, the on-load tap changer is used in conjunction with a saturable reactor connected in series in the rectifier output circuit.
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" ...
You said the car in the battery to charge its own (12V) is a rectifier. But can not put the 12-volt alternator, the power of the "rectifier" to 48 volts, rectifier: only the generator AC, through the rectifier into a DC charge into the battery, and can not be boosted to 48 volts, say the load is too large On the generator is influential, and its power is limited, can not be changed.
Q: What is the difference between a car voltage
The role of the voltage regulator is to adjust the output voltage of the generator, not to make the engine speed is high when the voltage is too high burned electrical appliances, the role of rectifier is the generator voltage is alternating current, and batteries and other electrical appliances need to be direct current
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?
The Of course, active filter filtering is much better than passive filter filtering, it can limit the current harmonic components within 3%. This is basically no effect on the grid, this filter is effective but expensive.
Q: Why is the battery connected to a rectifier
Charging current limiting function Currently access network site is almost all use of VRLA batteries, due to the tight assembly of the battery structure, in the high current charging, will cause the battery drums even heat out of control phenomenon, it must have a battery charge current limit Stream function. Battery over discharge protection function of the battery over discharge will have a great impact on the battery life, a depth of over-discharge may reduce the battery life of 1 to 2 years, and even cause the battery scrapped. Therefore, the rectifier over-discharge protection function is also an important indicator.
Q: Good motorcycle rectifier to what kind of performance, hope that people have not hesitate to enlighten me, I do not know how to compare the new car with a different performance of the rectifier better.
Switch type also have electricity consumption, the three input lines out of a, with a multimeter 20a exchange file series, increase the throttle to see the current instructions, the current is too large fuel economy is not good,
Q: Electronic ballasts and electromagnetic ballasts are different
Electronic ballasts can also have more features, such as by increasing the current frequency or current waveform (such as square wave) to improve or eliminate the flashing phenomenon of the fluorescent lamp; can also be through the power inverter process so that the fluorescent lamp can use DC power. Some of the shortcomings of traditional inductive rectifiers make it being replaced by increasingly sophisticated electronic ballasts
