What is the Wiener bus system

generatrix In the field of electricity, the busbar can also be called the busbar, busbar, etc., most of which refer to the busbar or power supply trunk in the high and low voltage cabinet, which is used to connect multiple electrical lines. The system will install various interface cards through the bus, and transmit various data to the devices connected to the interface cards.

(1) Air-type busway Since the mid-50s of the last century, represented by Beijing Baizhifang Airport Electrical Appliance Factory, the conductive row has been supported in the shell with insulating liner and insulated by air medium. The phase-to-phase distance is 50mm. (2) Secret ...

One of the characteristics of the Wiener low-voltage switchgear is the multi-functional busbar system. The bus bar is a conductor that connects large electrical equipment such as generators and transformers with various electrical devices. The role of the bus bar is to transmit electric energy with the, and the bus bar is the main equipment constituting the electrical wiring. ...

1. Select the type of fuse according to the line requirements and installation conditions. Circuits with small capacity are semi-enclosed or enclosed without fillers; The selection of large short-circuit current has a packing closed type; Semiconductor component maintenance selection of quick fuses. ...

Closed busway is a busbar system composed of metal plates (steel plates or aluminum plates) as protective shells, conductive strips, insulating materials and related accessories. It can be made into a piercing closing bus with spaced piercing junction boxes, or a feed-in closing bus without a junction box in the middle. ...

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.

There are three types of maintenance commonly used in medium and low voltage bus systems: (1) Transformer backup overcurrent maintenance (typical maintenance action time is 1.2s - 1.4s) (2) Transformer voltage with feeder quick-break maintenance locking ...

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 ...

1. Connecting copper plates, insulating plates, and insulating piercing screws generally refer to tension spring brackets, bus connectors, connecting copper bars, and plug-in boxes. The bracket is used for buffer busbars to squeeze each other during connection, and the adapter is used for connection. The connecting copper bar is the local use of the box and the bus connection of the cabinet connection. ...

1. Commonly used busbars, useful categories 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. According to its material ...

1. It has a modern beauty; 2. Small dimensions; 3. Strong and light weight, simple operation; 4. The connection is very simple (just like connecting water pipes, connecting sections through tees, elbows and other joints to make them into a system; ...

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 ...).

The grounding of the DC system should include two conditions: 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 they do not cause any harm when generating a ground current because there is no path to constitute a grounding current, but the ground of one pole is long.

(1) For the charging of the spare bus, when there is a bus tie circuit breaker, the bus tie circuit breaker should be used to charge the spare bus. At this time, the maintenance device of the bus tie circuit breaker should be fully invested, and the relevant maintenance value and time limit should be changed to a small size, so that when there is a problem with the bus, the bus tie circuit breaker can be quickly tripped, cut off...

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.

The bus equipment has the characteristics of beautiful appearance, compact structure, agile installation, easy to use, economical and time-saving, safe and reliable, and is one of the important parts of the low-voltage power supply system. Many scholars have conducted a multi-faceted discussion on the low-voltage bus system, and after many years of production, the bus body ...

In order to ensure the safe and economical operation of the power system and its power generation, supply and electrical equipment, power grid users require the voltage to operate in three ways: forward voltage regulation, reverse voltage regulation and constant voltage regulation. However, when the power grid is in practice, due to the change of active and reactive power output, the increase or decrease of electricity load, and the system wiring party...

At present, China has five power supply systems: IT, TT, TN-c, TN-c-s and TN-S. They have their own advantages and disadvantages, and we should choose sensitively according to the actual situation in life. Five power supply systems 1.IT power supply system In a ...

Bus load guessing is a kind of power system load guessing, and the bus system load can be defined as the sum of the terminal load of a relatively small power supply area supplied by the main transformer of the substation, which is the refinement of the system load. Bus load guessing generally only carries out short-term load guessing, and the result is ...

Busway (referred to as busway) is a busbar system composed of metal plates (steel plates or aluminum plates) to protect the shell, conductive bars, insulating materials and related accessories. It can be made into a plug-in closed bus with plug-in junction boxes at intervals, or as a feed-in type without a junction box in the center ...
