In today's information society, the computer room is a very common equipment, so the most important thing in a computer room is the bus system, which is the center and skeleton of the power distribution of the entire computer room. Then a reasonable bus system will greatly improve the efficiency of the computer room. So how do you optimize ...

The out-of-phase shut-off bus adopts a fully connected structure, with optimized design, reasonable design, stable and reliable operation. Choose either natural cooling or forced air cooling. The out-of-phase closing bus is to support the conductors of each phase bus with insulators and close them in their respective shells, and the shells themselves are electrically connected, ...

If you understand the scope of application of the busway, you can see that the excellent effect of the busway has the upper hand, which has a lot to do with the structural features. Therefore, if you want to have more confidence with the bus duct, you still need to understand it from the structural characteristics. At a time when China's economy is developing rapidly, ...

1. To carry out work in all and part of the energized panels, the equipment should be overhauled and separated from the operating machinery and equipment with obvious markings. 2. The secondary winding of the voltage transformer and the transformer should have reliable grounding maintenance. 3. On the secondary circuit of the voltage transformer in operation...

The so-called "section" of the bus bar is that the data that constitutes the bus are directly connected, and there is no circuit breaker or blocking switch in the center. A circuit breaker or barrier switch in the center is called a "segment". Different voltage levels cannot be connected in the same section. No...

　　In the common DC bus system of multiple inverters, especially the common DC bus of inverters of different power levels, it is very important that the connection between the bus bars is maintained by fuses. When one of the inverter power equipment in the common bus is damaged by short circuit breakdown, the other inverter bus ...

The advantage of the busway is that its structural design is simple, it is composed of metal plates, which can connect the circuits together, so as to achieve the safe and reliable transmission of electric energy. In addition, its structural design can effectively assist in reducing the occurrence of short circuits, reducing heat loss, and can effectively ensure the power ...

1. Before the bus duct installation, it should be ensured that the electrical shaft, substation and distribution room, the decoration project of the place through which the bus duct passes, and the heating and ventilation project are all completed to ensure that the bus duct is not polluted. The reserved holes and embedded parts of the floor and wall should be embedded and reserved according to the position required by the design. The functions of the busway are single ...

Bar switches are different from regular switches. They are critical to ensuring effectiveness. For example, when the current exceeds a certain amount of time, they cause heat to be generated, allowing the fuse to switch the fuse to further assist in breaking the circuit. Therefore, as a kind of current protection device, they can achieve ...

1. Crevice corrosion When there is a gap between the surface of the tubular bus itself and other things, the corrosion in the gap will be accelerated due to the difference in the effect of the inflatable battery, but there is no effect on the outside of the gap. However, crevice corrosion has little to do with the type of alloy, because even very corrosion-resistant ...

1) Closing the bus duct can reduce the grounding fault, prevent the short circuit between the phases, and fundamentally eliminate the grounding fault caused by external moisture, dust and foreign objects, and improve the continuity of generator operation. 2) Eliminate the surrounding ...

Since the busway is made of copper bars or aluminum as conductors, it has a large current capacity and good electrical and mechanical properties. In addition, it is made of a metal trough as the shell, so it is non-flammable, safe and reliable, and has a long service life. Compared with traditional power distribution or ...

1. Energy saving: The energy fed back when the motor brakes can be used, so it is more energy-saving, especially for oilfield kowtow machines, cranes and other lifting equipment. 2. The power element of the equipment is high: because the motor can feed back energy, the reactive power loss is small, so the power of the equipment ...

1. Closed busbar hooking technology Circuit breakers and contactors can be hooked on the bus through the bus adapter, and fuse switches and other products are directly attached to the bus, so the bus bar plays a two-layer effect of conductive and fixed rotation.

Bus, transformer, generator set unit wiring. It has the characteristics of simple wiring, less switchgear, easy operation, suitable for expansion, and because there is no generator outlet voltage bus, the short-circuit current of the low-voltage side of the generator and the main transformer is reduced. ...

Busbar refers to a product made of copper (copper bar) and aluminum materials with high conductivity to transmit electric energy and have the ability to gather and distribute electricity. The main conductor used by the power station or substation to transmit electrical energy. Through it, the electrical energy output from generators, transformers or rectifiers is delivered to individual users.

The grounding electrode is a discharge channel that connects current or voltage to the earth, and in order to reduce the grounding resistance, the electrodes that form the grounding grid are generally used in groups. The grounding bus refers to the connecting wire that connects the current or voltage to the grounding grid, or the conductor that connects the grounding electrode into one. ...

1. Busway horizontal device, the interval between the two brackets is ≯2500mm, and the interval between straight devices is ≯3600mm; 2. When the device bracket is straight, it should be drilled with the channel side plate and fastened with M6-M8 bolts. 3. In the process of installation construction, priority should be given to the power supply system, ...

Busbars are divided into hard busbars and soft busbars. According to its different shapes, hard buses can be divided into: rectangular busbars, tubular busbars, trough busbars, diamond busbars and so on. Rectangular busbars are the most commonly used busbars and are also busbars. ...

1. The cable in and out of the bridge is not piping 2. The orientation of the bridge grounding and crossing is incorrect, and the special grounding line of the spray or painted bridge device is not equipped with a special disc gasket 3. The fireproof board of the electric well is not fixed, and the fireproof plugging is not perfect 4. The bridge is opened at will, and no standard accessories are used.
