CabinetBothGroundingIt must be insulated from the earth There is no conflict between grounding and insulation. The earth refers to the electrical grounding professionally mentioned. the grounding of the computer room is also grounded. It is impossible to achieve absolute insulation because the earth is a conductor, but it is necessary to ensure that the distance

Nowadays, switching power supply has replaced linear regulated power supply and is active in the electronic power design field. People gradually realized that the switch power supply has changed the technical direction of the electronic design industry. In the power supply design, safety is always the first priority. In the switch power supply, grounding can protect the user's personal safety and ensure the normal operation of power equipment, so what

Integrated Wiring Grounding SystemPay attention to the following issues during design: 1. When the Integrated Wiring System adopts shielding measures, the continuity of all shielding layers should be maintained and the relative positions between wires should be kept unchanged. The FD or BD end of the shield layer shall be grounded, and the user terminal equipment shall be directly grounded according to the specific situation. The

In the grounding system, grounding wire production and installation is very important, the following for this introduction. One, grounding resistance requirements: 1, resistance to less than 4 Ω. The size of the grounding resistor can define the size of the grounding c

~ 1. Digital, analog, and power supply on the Board: From this figure, we can see that the analog and digital locations are completely separated, and finally each point is connected to the power source, which can prevent the mutual Crosstalk of the ground signal from affecting some sensitive components, as we all know, digital components have a higher Interference tolerance than analog components, while the noise on the digital ground is generally large, so separating them can reduce

1. When the integrated wiring system adopts shielding measures, all shielding layers should be kept continuous, and the relative position between conductors should be ensured. Shielding layer of wiring equipment (FD or BD) end should be grounded, the user (terminal equipment), depending on the specific situation directly, both ends of the grounding: should try to connect to the same grounding body. When the

On printed circuit boards, power cords and ground wires are the most important. The main method to overcome electromagnetic interference is grounding. For the dual panel, the ground line layout is particularly exquisite. By using the single point grounding method, the power supply and ground are connected from both ends of the power supply to the printed circuit board. The power supply is one point, one poi

really do the whole screen. At the same time, shielded cable shielding layer of low frequency magnetic shielding effect is poor, can not resist such as motor and other equipment produced low-frequency interference. Therefore, the use of shielded cable can not completely eliminate electromagnetic interference. Theoretically speaking, in order to reduce the outside world, shielding measures can be used to shield both electrostatic shielding and magnetic shielding. The principle of shielding is t

the low-frequency magnetic field and cannot resist the low-frequency interference caused by equipment such as motor. Therefore, shielding Cables cannot completely eliminate electromagnetic interference. Theoretically, in order to reduce the external world, shielding measures can be used to shield static shielding and magnetic shielding. The shielding principle is that the interference current is short-circuited to the ground after the shielding layer is grounded. Therefore, it is very important

Safety inspection of integrated wiring grounding system When the integrated wiring system adopts shielding measures, it must have a good grounding system and conform to the following regulations: (1) Protection ground grounding resistance value, the separate

be worse than that provided by the unshielded system. Part 1 installation of the shielded Cabling System The installation of the shielded wiring system mainly involves two aspects: the floor wiring room and the work area shielding cable terminal and system grounding. In view of the particularity of the shielding system, it is necessary to ensure that the Screen Layer of the cable is in good contact with the Screen Layer of the module and the distribu

security. For a shielded cabling system, we need to pay attention to the following two points during design and construction: 1. The function of the shielded cabling system requires that all connected hardware use shielded products, including transmission cables, distribution frames, modules, and jumpers. 2. The shielded cabling system must be correctly and properly grounded. If the shielding layer of each connection element of the transmission channel is discontinuous or poorly grounded, the t
