Standard parameters of busway specification - Wiener

Busway was born in the United States, first put into practical use in Japan, and then spread all over the mountains and regions in prosperous countries and regions. So what is a busway? Busway is a high-current trunk tappable power supply system, usually made of a metal housing (iron or aluminum).

1. Three-phase AC power supply inlet The power input of each inverter is connected in parallel on the same AC bus, and the power supply phase of the input of each inverter is consistent. In Figure 3, the circuit breaker QF is the incoming protection device for each inverter. LR is an incoming reactor, when multiple inverters are in the same ...

The use of insulated tube bus in China has a history of nearly 20 years, and it has made a historic contribution to reducing the layout space of the distribution bus and improving the reliability of the bus operation. There are many manufacturers who supply this product, and their production processes are uneven, and the differences in processes are mainly reflected in the ...

The novelty, flexibility and originality of the busbar device appliance. It indicates the vitality of this skill and its broad market prospects. This is the real reason why we pay attention to it. First of all, this small electrical appliance set ...

　First, this kind of small electrical equipment is a novel concept, adopting the "non-hole lap technology", and the electrical equipment is directly installed on the confluence bus system to form a power distribution or control loop. The representative creations are busbar device fuses and fuse load disconnectors. ...

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 ...

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 ...

Compared with other air-type busway, Wiener closed busway has many similarities in appearance, and its difference lies mainly in the shell, the structure of the closed busway is more distinctive, which also makes its use have certain advantages. As long as it is in contrast ...

The protection level mark of explosion-proof distribution box is the protection level of IP products that we often mention, which has two parameters, one represents the level of avoiding foreign objects from entering the shell, and the second represents the level of waterproof entering the shell. Installation of explosion-proof ...

In the selection, the following elements should be fully considered: fire protection specifications, insulation layer to flame retardant, good temperature resistance, high temperature is not easy to release harmful gases, structure type to avoid chimney effect, should give priority to the use of aggregate insulation layer bus duct, such as the use of air insulation type, it must be in the electric ...

Tubular bus is a new type of equipment that is widely used in our current days, and it itself has the characteristics of high current, outstanding insulation and wide range of application, so we don't seem to be too worried about its function and role when using it. But there is one thing that needs to be ...

Thorough differential maintenance of the bus is to connect the current transformer of all the connecting elements on the bus to the differential circuit according to the same name phase and polarity, the characteristics and transformation ratio of the current transformer should be the same, if the transformation ratio can not be together, the compensation converter can be used to compensate, satisfactory ΣI=0. ...

At the time of the cable tray installation, the wiring is not very convenient. This phenomenon can be avoided by using busway. The 5 advantages of using busway in the cable tray device are as follows: 1. Convenient connection of bus duct: the so-called plug-in bus...

The bus bar is an intermediate link in the voltage distribution device at all levels, and its role is to gather, distribute and transmit electric energy. It is mainly used for the connection of the electrical main circuit between the power plant generator outlet line and the main transformer, the plant transformer and the distribution box, also known as the busbar. ...

Precautions for the device VDE 0660 Specification Section 107 / EN 60947-3 Specification / IEC 60947-3 Specification 3 poles are broken at the same time, double breakpoints. Operator-independent, safe opening/closing, in position ...

When the busway has not been developed and introduced, the cable is still an indispensable figure in the low-voltage distribution system, when the busway system is introduced and widely used. Whether to choose the cable or the bus duct has become a topic of endless debate. So it's hard to say which of the two is better ...

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. ...

What is a tubular busbar Tubular bus bar is a kind of bus bar product with copper tube or aluminum alloy tube as conductor and external insulation. The tubular bus has the characteristics of high current (12000A), high mechanical strength, good insulation, wide application range, etc., ...

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, ...

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.
