Introduction to busbars in Wiener's electrical 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 ...

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 ...

The bus system divides the bus into hard bus and soft bus. The 60mm bus system refers to the three-wire or four-wire bus with a distance of 60mm. 1. In the 60mm bus system, the different cross-sectional areas of rectangular copper bars or special-shaped copper busbars such as 2T and 3T can be used to achieve the best classification of current intensity grades.

Most of the bus duct is the design standard for indoor use, so even if the humidity in the indoor air is relatively high, it will not have much impact on the operation of the busbar, but the bus duct enters the water during the use of the busway, which will definitely cause a certain degree of impact.

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. ...

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 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...

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 ...

Thanks to the precisely developed housing size, current transformers can now be integrated into all major products in a very space-saving way, such as: QUADRON®185Power Speed disconnector fuse set QUADRON®185Power Fuse Isolation ...

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.

1. Rapid device Today, busway adapters cannot be flipped at the time of installation, and the two busway sections are not out of phase when flipped when connected. 2. High protection level The coupling box has a protective function, ...

The common box closed bus includes the non-phase isolated, common box closed bus, phase isolated common box closed bus and AC and DC excitation common box bus, which are used for current transmission between the generator lead wire below 100MW and the low-voltage side of the main transformer or between the low-voltage side of the transformer and the high-voltage distribution device of the unit of 75MW and above.

According to the different uses of the bus duct, the bus groove is generally composed of the start bus slot, the straight bus slot (no partition jack and jack), the L-shaped straight (horizontal) curve bus, the Z-type straight (horizontal) offset bus, the T-shaped straight (horizontal) tee bus, the X-type straight (horizontal) cross-way bus, the variable ...

XBT series mine flameproof communication cable distribution box has the characteristics of small size, reasonable cable import and export, and wide coverage. Each distribution box has 4-10 inlet and outlet bells, which is suitable for HUYV type mine signal cable in coal containing sexual gas (methane) mixture (non-mining face).

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 ...

The communication and connection skills of the independent power supply system create better prospects for the power supply of the future. Hundreds of systems around the world have installed SMA's Sunny Island battery inverters to supply power to customers for a long time. The stackability of Sunny Island, i.e. multiple Sunny Islands ...

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.

1.It is necessary to install arc light maintenance Arc maintenance in foreign countries has nearly 20 years of history, the first set of maintenance devices in 1995 has been put into operation, China's previous imported units in the introduction of foreign complete sets of arc light maintenance (such as Guohua Tianjin Panshan Power Plant), domestic units ...

In power distribution equipment such as voltage distribution cabinets and switchgear at all levels of power plants and substations, the conductors connected between large electrical equipment such as generators and transformers and various electrical equipment are called busbars. Busbars, also known as busbars, are used to gather, distribute, and transmit electrical energy. The connection methods of the bus bar are ...

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 ...
