 The thyristor trigger circuit in the direct converter is a functional module controlled by computer, which is a completely intelligent management control system. Because of the computer management of the circuit, the probability of misoperation caused by the system mistriggering can be greatly reduced, and the auxiliary components outside the Control Circuit are also greatly reduced. If you look at the COSCO 27000t multi-purpose shipbuilding plant system built by our company (also supplied by Siemens) , you will see the real reason why the Siemens designed this system. Siemens relies on its own brand effect and the advantage of human resources to introduce people's ship power equipment, that is, to capture the market of advanced people's ship power automation high-end control equipment, they are keen on the application of computer intelligent management system in ship power station system or large-scale PLC control system. It is precisely in their eyes that this kind of system can not only manage large-scale, especially some more complicated systems, it can also take the form of a combination of language and solid devices to replace the previous need for a large number of solid components to complete the same task of the system. The secondary water supply is a key problem for the district and high-rise residential buildings where the pressure of municipal pipe network is not high. Because the water supply of high water tank is not ideal, and the property management is difficult to clean, it is difficult to ensure the sanitation requirements of water quality. Variable frequency speed regulating water supply equipment is composed of many water pumps and electric control equipment. According to the changes of pressure and water consumption in the pipe network, the variable frequency high speed device can adjust the rotational speed of each water pump and change the total output flow of the water pump, to meet the user's water demand at any time.

我向远处望去，看见了各种各样形态各异的巨石，横卧在大峡谷内。这就是有名的“万石布阵”，有的像一只巨大的青蛙趴在那里，这是石蛙阵;有的像在湖边戏水，这就是四象阵。不远处，还有一个玄关阵。
