1. Crevice corrosion When there is a gap between the surface of the tubular bus itself and other things, the corrosion in the gap will be accelerated due to the difference in the effect of the inflatable battery, but there is no effect on the outside of the gap. However, crevice corrosion has little to do with the type of alloy, because even very corrosion-resistant ...

In the industry, tubular bus bar can be described as one of the more common equipment, with high mechanical strength, good insulation, wide range of application and other characteristics of many enterprises. So do you know what are the ways to link tubular busbars? ...

1. Reliable insulation method There is an insulating layer on the conductive row, and there is a certain air yard between the phase and the phase, and there is an insulating pad block limited by DMC data between the conductive row and the shell, triple insulation, to ensure that the insulation of the bus duct is full of certainty, especially in the humid environment.

The out-of-phase shut-off bus adopts a fully connected structure, with optimized design, reasonable design, stable and reliable operation. Choose either natural cooling or forced air cooling. The out-of-phase closing bus is to support the conductors of each phase bus with insulators and close them in their respective shells, and the shells themselves are electrically connected, ...

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.

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 ...

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. ...

In general, the DC power supply system is composed of a communication screen, a rectifier screen, and a DC screen. After selecting a dense bus duct, it is necessary to adjust the conventional DC power supply system: one or two large-capacity DC split-screens are installed in the communication room, and a large loop output is set in the DC split-screen; In the power room ...

First, in the CAD system drawing, it is a plan of the bus duct, and two parallel polylines can indicate the bus duct. 2. The busway includes the following parts: 1. Feeder busbar, which is used to transmit electricity 2. Plug-in busbar with plug-in interface above, ...

The plug-in busway has a high 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 105C is selected for the insulation material 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 ( ...

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 ...

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.

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 ...

If there is a problem in the bus duct of the double bus wiring, it is necessary to pay attention to the operation mode of bus maintenance in the process of dealing with the problem, and if necessary, the bus maintenance should be stopped for a short time. After the bus voltage disappears, the dispatcher should immediately swing the switch (including the bus tie switch) that may call, and notify the operation team to ...

The rectangular bus has good heat dissipation performance and is easy to fix and connect. But its skin effect is quite large. In order to reduce the skin effect, the cross-sectional area of a single busbar should not exceed 1250 square millimeters. When the working current exceeds the promised current of a single bus, 2 to 4 rectangular buses can be used. Rectangular conductor a ...

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.
