The three-phase power supply three windings of the end, X, Y, Z joined together to become a common point o, from the beginning of a, B, C leads to three end-line, which is called "star-shaped connection method" also known as "Y-shape connection method." Three-phase power supply is the same frequency, the amplitude is equal and phase in turn 120 ° three sine power supply in a certain way connected to the external power system. The three-phase power supply connection method has the Y shape and the

1 People for Wake Power detection In short, it is to connect the computer motherboard 20 pin plug, with a wire (such as a thin wire, the specific people to play the imagination) a green line, a black line (there are 8), if the power supply fan turned on the power is good. With a thin wire to the ATX plug 14 feet ps-on and the other end of the 3rd, 5, 7, 13, 15,

So, the merchant said "original XX line", may not be original, how to polish your eyes, distingu

Although the laser printer models a lot, but because of its working principle and the use of materials are basically the same, but some specifications are different just so, for the general maintenance of laser printers, basically can be suitable for a variety of laser printers, but some special differences just. 　　Maintenance of electrode wire As the printer has residual toner, dust and confetti and other sundries, charging, transfer, separation an

Here we use the example of the notebook to describe the adapte

Home decoration is inseparable from wires, especially in old houses. Although the wires are small, "responsibility" is significant. Many fires are caused by aging of wire lines, unreasonable configuration, or poor quality of wires. Therefore, consumers must polish their eyes when purchasing power lines and identify them carefully to prevent problems.Single-strand copper wire. lighting: 1.5 square meters, an

We know that a gigabit port's wire-speed packet forwarding rate is 1.4881MPPS, The speed packet forwarding rate of the gigabit port is 0.14881MPPS, which is the international standard, but how is it obtained? The specific packets in the transmission process will be preceded by each package 64 (leader) preamble is a 64-byte packet, originally only 512 bit, but in the transmission process will actually have 512+64+96=672bit, That is, the length of a pac

interference caused by electricity and Ground Wires should be minimized to ensure product quality.For every engineer engaged in electronic product design, he understands the reason for noise between the ground and the power cord. Now he only expresses the noise reduction:(1) It is well known that decoupling capacitors are added between power supplies and ground wires.(2) try to widen the power supply and ground wire width, preferably the ground

elevator expands and more people can be installed,The elevator is good, but the company will recruit more people, there are more people, then change the elevator, then recruit people... there is always an endless loop, and there is a good way to do it. Everyone simply doesn't want to take the elevator and jump down directly. No matter whether it's on the second or third floor, it will definitely solve the problem, but there will certainly be problems (1st were shot down)2ndInstall two elevators

distance must be greater than or equal to 4 mil, and the distance between the hole and the hole should not be less than 8 mil. I usually use 10 mil wire width and safe distance, and use 12 mil for copper laying. If any manufacturer has broken down the boards of this condition, change the manufacturer!

high-impedance state, it is used as the input port. link_data can be controlled through related circuits.2. When writing a test module, the inout port must be defined as a wire variable, while other input ports must be defined as Reg. There is a difference between the two.When data_inout is used as the input in the preceding example, You need to assign a value to data_inout. In other cases, you can disconnect it. In this case, you can use the assign
