First emphasize yourself as a fungus (don't think too much)! Beats SOLO HD wired headsets have been used before, because in the office in order to not affect other colleagues and to work or leisure time, they can quietly listen to music or listen to logical thinking. The reason why solo was chosen was because he feared that once the noise had been actively eliminated, there was no way to listen to it. As the saying goes: The old ones are not new. Years ago took his son to see the "bear infestation" movie, perhaps due to the darkness of the theater. In the process of the mobile phone, the headset was even dropped (the line was still there) and missed it! Sadly! Ever since you want to start with a headset, in order to cover up the grief began to want to choose the wireless version of the solo, because no electricity can be used when the wire. When hesitated, she saw Zhang Dafa push a message in the evening The price has advantages, and can be used when there is no electricity, because it is the sound quality and parameters do not understand the fungus, the key to see the official endurance parameters are very high for 16 hours, can fully meet the demand, but also active noise reduction. An Amazon Trial Member was selected to eliminate postage. And the first renewal looks like 188, and now hesitates whether to renew the fee, because the value of the Dongchao tea is a plus. Almost everything is bought from the owner of the tea, not only not saving money, but instead. . . . Products from the delivery, rice - China, took only 3 days, the results to catch up with the Spring Festival, the information prompts incomplete documents, has not been released, then contact Amazon customer service, customer service informed, Customs holiday, February 3 to know Xinxiang The result was released on the 3rd. See the efficiency of my DPRK. It is true that the people of the U.S. do not have a tape on the edge of the overseas transport, and there is no shock-absorbing measure for the packaging. It is thus shipped from a foreign country. Is that compliment or criticism? In this way, no tape was on both sides, and even a piece of paper was not lost. The items were intact. Maybe it was thrown away early in the hands of the Celebrate courier. The goods may not be possible... The products are all written in the rice language. As a result, ma de in China, from mainland China to the rice country, and then from the rice country to the mainland, the mainland has yet to sell it. ! Saying that this packaging is too simple a plastic packaging a carton, even a simple storage bag is not, maybe a big brand, may be a cost factor, maybe environmental protection, focus on value in the moment, put more thought on the first look Today's (especially domestic electronic goods) is really too shabby, and it is hoped that brand owners will use their minds in their products. This PHILIPS SHB8750NC/27 active noise-free Bluetooth headset is all black, and the same style as the box, no more fancy design, giving a simple and generous, calm and steady feeling, more grades. Beats headphones and distinguish between the two styles, do not install B, not vulgar. SHB8750NC is marked with uppercase L and R in the eye-catching position of the headband, so there is no need to worry about the left and right issues. In addition, multi-angle folding is more convenient for earphone storage. Most of the function keys are focused on the right side of the SHB8750NC. It's easy to press the wrong key to see the ghosts' evaluation that the buttons are too centralized and inconvenient to control. This is actually the case, unless you are using a specific location where you know each button more than once. The nc is SHB8750NC Bluetooth headset supports active anti-noise function, next to the indicator. When it comes to noise reduction, everyone should be familiar with it. Active noise reduction means that the noise generated by the noise reduction system is equal to the external noise and the noise cancels out. This function key is set on the left earphone of SHB8750NC. Try to press and hold for more than 3 seconds to turn on the indicator light to turn it on. In the process of audiovisual experience, when no music is played, active anti-noise function is activated in a noisy outdoor environment, and the noise reduction function can be obviously felt. In addition, the environment is quiet and there is no sound source, there will be a weak case. Current sounds can be ignored without careful listening. In public places such as high-speed trains, subways, and airplanes where the environment is noisy, this headset can also be used as a soundproofing device. It is better to use the earplugs than normal earphones. Head beam can be adjusted in size, SHB8750NC set 6 lengths of adjustment, to facilitate all types of head! The wire is really unsatisfactory, a headphone cable, a charging cable (Micro USB interface), and the wire is very small, unlike the big brand products. Here is the contrast of my Beats SOLO HD cable, obviously a lot, but there is a It was found that the Beats cable could be plugged in and plugged into an Apple phone to adjust the volume. Although the color is not too good, it is better than the original wire regardless of length and ease of use. The earmuffs should be made of protein material. The memory foam ear pads can easily conform to the auricles of the human. The soft skin-friendly ear pads do not deform and provide comfort for long-term wear. But when it's hot, it's estimated to be uncomfortable. According to the official introduction on the left side of the headset has NFC function, with nfc function phone close to the left earphone can play the sound source, but I am iphone6p, looks like nfc is only valid for the apple pay, and there is no test distance and ease of use, to be valued friends Development. Up to 97% reduction in ambient background noise Compatible with Bluetooth 4.0 devices, hands-free calling free your hands Built-in rechargeable battery for up to 16 hours of wireless playback Simple and convenient NFC connection Launch Siri and Google Now services with one click SHB8750NC can be found on the mobile phone after booting, and the connection is quick. After the wire is plugged in, the Bluetooth connection is turned off and the wire source is turned off. The Bluetooth connection is stable and reliable. There will be no sound loss within 10 meters, and no disconnection is found at every other wall. It is worth pointing out. The Bluetooth button on the headset has the Siri/Google Now feature. Click once to connect directly to Siri. The instructions are concise, easy to understand, and do not require Chinese to learn to use Because it is fungus, they dare not come to work. The headset uses a 32mm high-intensity drive, from the actual experience, the bass is loud and clear, it is worthy of praise, high-pitched detail processing is also in place, there will be no broken sound, remarkable. Because of the price, it is estimated that there is still a gap with the thousand-dollar headphones. Less than 300 yuan price of the existing active noise reduction, Bluetooth 4.0 and NFC wireless connection, and a call function, battery life 16 hours. It can be worthwhile to be able to use the wire to connect in the absence of electricity, not to panic, and it is worth choosing. It has recently been found that the price has climbed to 499 yuan. Whether it is an office listening to music, a subway, a plane, a bus, or other noisy place, or a gym listening to music, you can use it in various situations. Color reasons, not like people feel like it is installed in the Beats 13, it seems that many young people are now used to show off the headset rather than use, resulting in a treasure is full of cottage version of headphones, spread the train is noodles headphones everywhere, people what! ! ! After one hour of wearing, there will be some discomfort. It will vary from person to person, but listening to the song for a long time will also cause you to feel tired. You need to take it down and adapt to other environmental sounds. In short, a few hundred Bluetooth headsets are worth recommending!
Scope of supply
Rating: Up to 200MVA
Voltage:Valve side voltage up to 1000VDC, Grid side voltage up to 220KV
Double star and double bridge
Applications:
The rectifier transformers are
mainly used in the electrolysis processes for production of different kind of metals,
such as aluminum electrolyzing, magnesium electrolyzing, copper electrolyzing,
zinc electrolyzing and other more applications. The largest installed rectifier
transformers are always for aluminum electrolysis with some
transformer/rectifier combined units in parallel operation to get the required
DC current.
Design:
The rectification
method is normally known as double
star or double bridge. Double
star systems use an interphase transformer (IPT) and are usually
applied as 6 or 12pulse units where high currents are required with very low
nominal voltages. Double bridge
system is applied as 6, 12, 24, 48 or 60pulse systems, as required
to suit the harmonic mitigation and process stability requirements.
Duty
Electrolysis is normally a
continuous process, but with a constant high loading and current harmonics.
