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.

First introduce the main parameters of the Thai letter box: 
From the hardware configuration point of view, all the functions of the cable TV broadcast network intelligent set-top box are integrated, which is exactly what we need.

Thai letter box T1 has a white ceramic paint surface, the overall size of 102x110x30.5mm, lightweight and compact, easy to place. There are fan-shaped cooling slots on the front and dense heat dissipation holes on the bottom. At the same time, there is an aluminum plate in contact with the main heating chip through the heat-conducting material. The upper and lower transparent heat-dissipation design can quickly take away more heat generated by the chip. Thermal efficiency is very high. It is not only the single-core processor currently used, but also more core cores will be upgraded in the future, and heat dissipation will not be a problem. 
The interface of the Tektronix box T1 is mainly distributed in the back and two sides, and the front is mainly four status indicators, infrared remote control receivers and touch switches. Interface includes infrared expansion jack, TF card slot, 2 USB, power jack, HDMI high-definition output, RF coaxial input, RJ-45 network port, AV and color difference analog output jack and cable TV smart card slot. Among them, the cable TV smart card slot can be inserted into the smart card used in the current home cable set-top box to play the cable television. This function needs to cooperate with a third-party application and can be used in many places. The Tektronix box T1 supports HDMI high-definition output, and also provides AV and color difference analog output connection methods for old-fashioned TVs without high-definition interfaces. After all, compared to the new smart TV, it is more practical to make the non-intelligent old TVs in the homes smarter and rejuvenate their vitality. The Thai T1 box can turn your old TV into a smart digital TV with the latest technology. This can be more than 500 yuan more than a regular TV. A T1 box allows your old TV to instantly double in value. 
Accessories, including the Thai box T1, DC adapter, infrared extension cable, remote control and a 1-meter HDMI HD cable. The remote control function buttons are very rich, and like the ordinary TV remote control, it is very easy to get started.
Thai letter box T1 boot trial:
Connect the Thai letter box T1 to the TV, insert the cable smart card into the card slot, turn on the power, and wait a moment to enter the system.

Of course, the software already contains most of the smart card's pairing information. The cable TV used by Xiao Bian is in this column, so use the default settings to directly initialize the smart card and exit. 
We click on the remote home button to return to the main screen. Select "Live TV" to display the regional settings prompt. After confirming, call up the "search setting tab", set the area and click Save and download. After the download is complete, you can watch live TV directly.
