Introduction to the Wiener busbar system

Although the service life cost of the bus system is usually lower than that of the traditional wiring method, the bus system still bears a considerable cost compared with other structural elements of the water supply and drainage or HVAC system. In addition, customized busbar equipment allows the busbar system to be routed around obstacles ...

In the hardware layout planning of the ship unloader distribution cabinet, in order to omit the wiring slot pawn, save time and effort in wiring, prevent wiring errors, and make the distribution cabinet beautiful and useful, the circuit breaker inlet end in the distribution cabinet will use the confluence method. Here are a few commonly used ways to combine the flow with Siemens circuit breakers.

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 for our attention. First of all, this small electrical appliance plant was conceived ...

The Wiener bus system is divided into 40mm, 60mm, 100mm and 185mm systems according to the upper and lower spacing between the copper bars, and the ship unloader distribution cabinet mainly adopts a 60mm rectangular bus system. This is shown in the figure below. The 60mm system provides maximum operating space and maximum current with its smallest external size.

When it comes to cable tray installation, 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 duct, fireproof bridge is the way it uses plugged in.

1. Requirements for civil engineering before installation 1. The foundation, frame, reserved holes and embedded parts meet the planning requirements of electrical equipment. 2. After the construction of the roof and floor slab, there shall be no leakage. 3. After the indoor above-ground construction is completed, mark the leveling elevation on the wall on the ground.

1. Bus system 1 The bus adapter used in bus system 1 is more miscellaneous, and -Q1 selects a bus type blocking switch that can be directly attached to the bus; -Q11 is a 3VL2 switch, select an appropriate universal adapter to hook up to the bus; The 3-pole switch-Q12——-Q15 is less than 63A, but ...

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. The conductor of the bus bar is a high conductivity TMY electrical hard copper bar rolled by T2 electrolytic copper, and the purity of copper must be ≥ 99.95%, and copper-aluminum alloy or other mixed alloy non-pure copper conductor materials shall not be used, and the copper plate is tin plated on the full length. 2. The raw material of the neutral wire and the phase wire in the bus system is the same.

Although the service life cost of the busbar system is usually lower than that of the traditional wiring method, the busbar system still bears a considerable cost compared to other structural elements of the water supply and drainage or HVAC system. In addition, customized busbars ...

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, mostly use bare wires or stranded wires of rectangular or circular cross-section, which are collectively referred to as busbars. The role of the bus bar is to collect, distribute and transmit electrical energy. Because the busbar ...

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. Prepare for replacement. For example, construction personnel should wear labor protection equipment, such as insulating gloves. 2. Confirm the fault type. Check the distribution box with a test pen first, confirm that there is no leakage, and then open the distribution box door. Then use the voltage tester to detect the three-phase power supply, if the three-phase ...

Plug-in fuse: It is commonly used at the end of the line at the voltage level of 380V and below, as a short-circuit maintenance for distribution branch lines or electrical equipment. Spiral fuse: The upper end of the melt is covered with a fuse indicator, once the melt is melted...

The nature is different Busbar: It is a common path on which multiple devices are connected in the form of side-by-side branches. Busway: It is a closed metal equipment composed of copper and aluminum busbars. Different uses Mother...

Single bus wiring method: all outgoing wires are connected to the same busbar, which is also the most cost-effective and simplest wiring method Single bus segmentation: The outgoing line is arranged in two parts on different sections of the single busbar, so that a power failure in the meantime does not affect the power supply of the other bus ...

1. Whether the scale of bus differential maintenance is determined, and whether the maintenance goal is unchanged Generally, differential maintenance includes bus differential maintenance, transformer differential maintenance, generator differential maintenance and line differential maintenance. The basic principle of achieving differential maintenance is common, i.e. on all sides or on each side...

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. Save space. The components are attached to the busbar, which can save 1/3 of the size of the box transformer. 2. Operation**. The busbars are placed behind the components, and the upper and lower plates can be sealed to prevent touch protection. 3. Improve the stability and reliability of operation, improve the dynamic and thermal stability, and the bus bar is not perforated.

The busway system is an efficient power distribution device, especially suitable for the needs of high-rise buildings and large-scale factories for reasonable wiring. With the presentation of modern engineering equipment and equipment, the electricity consumption of all walks of life has increased rapidly, especially many high-rise buildings and large factories. Traditional cables serve as ...
