Type of transmission

According to the nature of the current delivered, the transmission is divided into AC transmission and DC transmission. In the 1880s, the first direct realization of DC transmission. However, since the voltage of the direct current transmission is difficult to continue to improve under the technical conditions at that time, the transmission capacity and efficiency are limited. At the end of the 19th century, DC transmission was gradually replaced by AC transmission. The success of AC transmission has ushered in a new era of electrification in the 20th century. Three-phase AC transmission is widely used at a frequency of 50 Hz (or 60 Hz). Since the 1960s, there has been a new development in direct current transmission, which is combined with AC transmission to form an AC-DC hybrid power system.

CCD Explosion-Proof Camera refers to the sensor using CCD, and the CCD sensor transmits the charge data of each pixel in each row to the next pixel in turn, from the bottom part, and then through the edge of the sensor. The amplified output is made, so the CCD Explosion-Proof Camera ensures that the data is not distorted when transmitted, so the data of each pixel can be aggregated to the edge for amplification.
