a great impact on the suppression of higher harmonic waves. 3.1.1 The Third Harmonic circulation in the D-junction winding can generate the Third Harmonic Magnetic Potential in the transformer, which is balanced against the third harmonic magnetic potential of the Low Voltage Winding; 3.1.2 The Third Harmonic Potential of the high-voltage phase winding is in the central flow of the D-junction loop. The third harmonic current can form a circulation in the first winding of the D-junction so that

the access devices that collect and distribute electric energy. They determine the number of devices in the Power Distribution Device and indicate how to connect generators, transformers, and lines, and how to connect to the system to complete the transmission and distribution task.9. Current Transformer: The instrument converter is an instrument that converts large current into small current.10. Transformer: a static electrical device used to change the AC voltage of a certain value to another

installation of component bodies perpendicular to the circuit board. The advantage of welding is space saving. Horizontal refers to the parallel installation of components closely related to the circuit board and welding. Its advantage is that the mechanical strength of component installation is good. For these two different installation elements, the component hole distance on the printed circuit board is different. (3) The grounding point of the sa

the power line (VCC) and the ground.The lead of the capacitor should not be too long, especially the high-frequency bypass capacitor cannot be leaded.(3) in the single-chip microcomputer control system, there are many types of ground wire, such as systematically, shielded, logically, simulated ground, whether the ground is reasonable layout, will determine the anti-jamming ability of the circuit board.The following questions should be considered when designing ground and connecting sitesLogical

phenomenon of probe burning occurs. This is because most of the oscilloscope's "signal common line" terminals are connected to a protective grounding system, often referred to as "grounding". The result is that all of the signals that are applied to the oscilloscope and provided by the oscilloscope have a common connection point. This common connection point is typically an oscilloscope enclosure that conn

lines Overhead power lines: towers, foundations, cables, Grounding Devices, wires, lightning wires, fittings, insulators, ladders and nails, signs and ancillary facilities; Transformer, capacitor, circuit breaker, knife gate, lightning arrester, transformer and ancillary facilities on power line.

specifications of network interfaces to achieve the connection between buildings. 2) device SubsystemThe EIA/TIA569 Standard specifies the cabling between devices. It is the primary management area of the cabling system, and data on all floors is transmitted by cables or optical fiber cables. Generally, this system is installed in the host room of the computer system, network system, and NC control system. 3) Vertical trunk SubsystemIt connects communication rooms, equipment rooms, and entry de

radiation transmission mode. Therefore, from the disturbed sensors, the interference coupling can be divided into two kinds: conduction coupling and radiation coupling. The conduction transmission must have a complete circuit connection between the jamming source and the sensor, and the jamming signal is transmitted to the sensor through the connection circuit, and the interference phenomenon occurs. The transmission circuit may include a conductor, a conductive component of the equipment, a p

, armored layer to maintain connectivity. ② in accordance with the provisions of the ydj14-91, in the optical cable joints moisture-proof layer, armored layer and strengthen the core should be used for electrical disconnection, and are not grounded, the ground is insulated, can avoid the accumulation of inductive lightning in optical cables, It can also avoid the difference between the impedance of the lightning-proof line and the metal component of the cable to the ground circuit, which leads t

Fitbit upcoming IPO, this is a smart wearable company, the main products for health testing equipment, smart bracelet, smart watch. Let's take a look at some of Fitbit's data. According to its prospectus, Fitbit sold 10.9 million wearable devices in 2014, more than twice times in 2013. As of the first quarter of 2015, Fitbit sold 20.8 million devices from its inception. Its financial position in the past two years was also very good, with a turnover o

I like this question very much! First of all, I would like to describe this question as follows: necklaces and bracelets are made of several beads. The difference is that the necklace cannot be reversed, but the bracelet can be reversed, and give you n beads, t color, each color can be any multiple beads, ask you, how many kind of necklaces and bracelets can be constructed! I personally think this question is a classic example of replacement! At firs
