Avoidable failures in busbar systems – Wienal

On the medium and low voltage side of the main transformer, the bus tie switch and the original electromagnetic relay maintenance DC circuit of each outlet, the PLC is used for logical comparison to determine whether it is a fault in the maintenance area or a fault outside the area. ...

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) General bus duct Non-flame retardant and non-fire-resistant bus duct selected for general load power distribution. In the event of a short circuit, it will be incinerated until it is connected to other busbars, which can easily cause fire accidents. (2) Flame retardant bus duct ...

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, ...

Since the launch of the 185Power system in 2014, Wiener has continued to develop new connection technologies and fuse-type disconnector technologies for the 185Power system on the basis of the 185mm bus technology. In addition to the application of 1600A below ...

Bus line refers to a product made of copper (copper bar) and aluminum material with high conductivity to transmit electrical energy and have the ability to collect and distribute electricity. The main conductor used by the power station or substation to transmit electrical energy. Through it, the output of the generator, transformer or rectifier ...

The difference between busbar and cable The busbar is used to gather current. Many power and power supply circuits are connected to the bus, through which the power is gathered and sent to each circuit. Therefore, the current carrying capacity of the bus bar is relatively large, and the current carrying capacity of the bus ...

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. ...

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...

Bus refers to the connection of voltage distribution devices at all levels in the substation, as well as the connection of electrical equipment such as transformers and corresponding distribution devices, most of which use bare wires or stranded wires with rectangular or circular sections. The role of the bus bar is to collect, distribute and transmit electrical energy. According to the structure, the bus bar is divided into hard busbar, soft ...

Ambient air temperature: turn off the busbar system to benchmark the ambient air temperature; Unless otherwise ruled, the manufacturer should give an additional current to shut down the busbar system at a base ambient air temperature of 35°C; If applicable, the manufacturer should give an additional coefficient k: (K1=1 at 35°C) in order to determine the size of the package.

1. The plug-in bus duct has strong overload capacity The overload capacity of the bus duct is strong, depending on the high working temperature of the insulation material it uses, and the working temperature of 105 is selected for the insulation data used in the bus duct, and the radiation cross-linked flame retardant winding tape with a working temperature of more than 140 °C has been developed.

1. In the 60mm bus system, the square fuse type blocking switch can be directly hooked. 2. The 60mm bus system refers to the three-wire or four-wire bus spacing of 60mm. 3. Strip NH-fuse type load barrier switch with scale 00 ...

When switching on and off components, you should pay attention to the following: –In accordance with VDE-0105-100, only operation by electrical professionals or persons with electrical knowledge is allowed (operation without electricity, closing, disconnecting, and replacing fuses ...).

Modern power supply lines play a very important role like the aorta of the human body, and if something goes wrong, it can have serious consequences. Before the 80s of the 20th century, many stable cables were used in modern construction. With the rapid development of the city, the power load of the building ...

The grounding of the DC system should include two situations: the one-point grounding of the DC system and the two-point grounding of the DC system. In the DC system, the positive and negative poles of DC are insulated from the ground, and there is no grounding current when generating a ground current when one pole is grounded.

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 ...

The bus system plays a very important role in the practice of construction, and for products such as the bus system, the relevant items can not be ignored, so that we can better use the practical value of this type of product. Generally speaking, when we are purchasing a bus system ...

A new addition to the world of CrossBoard® systems: the MOTUS® hybrid motor starter with IO-Link interface is a new networking feature in the MOTUS® IO-Link family that enables continuous communication between the control and device levels.
