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: 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: Can the rectifier change the voltage?
- The correct call is "fluorescent lamp ballast", not the rectifier. The role of the ballast is: 1, fluorescent lamp start, the starter contact in the moment off, the ballast inductor electromotive force and power supply voltage superposition, the lamp mercury gas breakdown, to stimulate the fluorescent light. 2, the fluorescent light is lit, the ballast to play the role of impedance, limiting the current through the light.
- 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: 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 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: What is the difference between a car voltage
- Rectifier, the generator is the power of alternating current, simply that there is no positive and negative. And the car is basically all the electrical requirements of DC is also required to distinguish between positive and negative batteries, especially the electrical and various electrical appliances. The function of the rectifier is to convert the electric power generated by the generator into 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
- The purpose is to filter and reduce the impact on the battery, filter, reduce electrical equipment interference, so that sound more pure sound, power cleaner, reduce the impact of many devices are large power users on the battery instantaneous demand will make the battery Aging, early retirement, if there is a rectifier will have some power, electricity will not directly use the battery power, which play a protective battery, these rectifiers are basically large capacity inside the capacitor, the Internet has its own DIY.
- 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.
- I have seen the maximum power of the motor rectifier is 220w crazy 300w, the use of button-type switch pipe. Another kind of shunt-absorbing pure fuel-consuming king in the high-speed operation to the extra power consumption in addition to increase the heat, increase the engine load no other advantages, but more than 250 displacement motorcycle, mostly use this type.
- Q: Differences between electronic transformers and electronic ballasts
- Electronic ballasts can be simply modified into electronic transformers, the output of high-frequency voltage can also be converted through the Xiaoji Diode rectifier DC. There is no voltage regulator circuit, the output voltage will change with the power of the load, so this circuit is called the electronic transformer instead of switching power supply.
