Siliconrectifier of GKA series for switching closing
Siliconrectifier of GKA series for switching closing is designed according to GB2859standard, mainly used for high-voltage switching closing power supply in powerplants, substations, power stations and industrial and mining enterprises,which is controlled electromagnetically, DC power supply forprotection. The product adopts screen-type structure three-phase bridgerectifier circuit with capacitor energy storage, insulation monitoring, lackphase, over voltage, over current, power supply automatic cut off and other protectiondevices. Product allows the impact of 10 times under rated output DC current(short-term value) , the duration not less than 1S and not more than 3S, theimpact of time interval is 2S. Product is generally multiple type, also can bemade in single type upon customer’s request.
- Q: Characteristics of Electronic Rectifier and Ordinary Rectifier
- After the above static measurement, check the fault components, the circuit recovery, carefully check the circuit board on the solder joints and components with or without short circuit, touch, loose, broken place. After correcting the correct power, in most cases, the fluorescent can return to normal work, but may also occur the following transformer neutral point voltage failure, should be ruled out one by one.
- 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,
- Electronic ballast according to the different lamp and the number of output lines are also different, usually 6 lines, 2 connected to the power supply, the other four for each of the two groups of light on both ends of the lamp. But if it is a ring lamp, there are 2 lights and 4 foot of the foot, 2 lights of the lamp with the electronic ballast only four output lines.
- Q: The difference between rectifiers and transformers
- Fluorescent lamp ballast is because it starts with high current and high voltage, to be activated, only a lower voltage and a smaller current to maintain its working condition, it must be ballast. Other transformers are due to their rated voltage range, to be adjusted
- 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: Automotive electronic regulator is DC input, motorcycle rectifier is AC input?
- Automotive electronic regulator and motorcycle rectifier is not the same
- 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" ...
- General car engine around the limited space, and then installed 48v generator I am afraid there is no space, say there is no power out of the equipment, if there is space, and then have power out of equipment, you can install another set of power generation equipment. But he and the car generator power supply system is completely unrelated to another set of power generation equipment. Such as power generation is too large, will affect the engine power.
- Q: What is the difference between a rectifier and a DC / DC converter?
- DC / DC converters are complex. If it is high DC into a low DC, then it is relatively simple, (low power) with a regulator or resistance can be achieved, such as 7815 and so on. When the voltage difference is large, you can use SCR 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: 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: 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.
