Traction silicon rectifier of GQA,GQF,KGQF series

Traction silicon rectifier of GQA,GQF,KGQF series

Traction silicon rectifier of GQA GQF KGQFKGQA series are mainly used for ground electric locomotive traction and DCpower supply of electric locomotive traction in mine for mining enterprises.

The product adopts three phase full controlbridge, three phase half control bridge and diode rectifier, smoothingreactor added on full control and half control bridge to improve DC currentwave form, and restrict short current and keep current continuity. Three phasebridge input terminal uses vacuum AC contactor, load is E and 100% IH, 150% IH for 2 hours, 300% IH for1mintue, has flow cut-off protection function, can be operated under the shaft.

We provide rectifier transformer with threedifferent types: dry, epoxy cast resin and oil immersed.

Q:The difference between the rectifier and the inverter: Rectifier: refers to the DC power through the semiconductor, transformers and other components into the reverse process of alternating current, referred to as the inverter.

Q:The basic requirements of the rectifier: Input current Total harmonic distortion (THD) (total harmonic distortion THD: AC current harmonic current RMS value of the fundamental component of the effective value of the percentage) 6 pulse rectifier input current THD 6 pulse rectifier full load current Should be less than 33%; using input filter can reduce the input current distortion to 10%.

Q:Is the rectifier pulse the better?: The current output from the rectifier can be said to be infinitely impulsive. (Specific analysis please see Fu Li Ya class pulse formula) itself is the infinite amount, does not matter more or less concept.

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:What is the difference between the regulator and the rectifier?: Rectifier (English: rectifier) is the exchange of alternating current into direct current devices, can be used for power supply devices and detect radio signals. The rectifier can be made of a vacuum tube, a pilot tube, a solid-state silicon diode, a mercury arc, or the like.

Q:Automotive electronic regulator is DC input, motorcycle rectifier is AC input?: Regulator is more complex: electromagnetic, electronic, composite; transistor, integrated circuit, embedded, directly installed in the generators within the integrated, and so on;

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:Differences between electronic transformers and electronic ballasts: The ballast and it is not a thing at all, the ballast is the gas discharge lamp drive device, common is the fluorescent lamp ballast, there are inductive and electronic type, when the lamp starts to produce a momentary high voltage The gas is ionized in the lamp and then the lamp current is controlled to stabilize it. The electronic ballast is structurally similar to a half-bridge inverter circuit.

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: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.
