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.

Silicon rectifier of GKA series for switching closing

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:Electronic ballasts and electromagnetic ballasts are different: Electronic ballast (Electronic ballast), is a ballast, refers to the use of electronic technology to drive electric light source, to produce the necessary lighting of electronic equipment. Corresponding to the inductive ballast (or ballast).

Q:Why is the battery connected to a rectifier: Access network site is rarely equipped with air conditioning, so the ambient temperature changes, the internal chemical reaction speed of the battery has a great impact. Rectifier temperature compensation function is to minimize the impact of temperature on the battery. The general requirements of the ambient temperature for each rise once, each section 2V battery float voltage to reduce 3 ~ 5mv, and vice versa. As a result of a variety of batteries using different materials and materials, the actual application of the battery manufacturers to give the data to adjust.

Q:What is the difference between a rectifier and a DC / DC converter?: Rectifier is the converter current properties, DC-DC converter is adjusted to change the DC voltage

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: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: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: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: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: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 function of the regulator rectifier is both rectified and regulated. The difference between the full-wave regulator rectifier and the half-wave regulator rectifier is that the rectification effect of the AC waveform is different.
