The busway is one of the more critical components in the power system, and it is an important part of connecting cables to important equipment such as substations, overhead lines, transformers, circuit breakers, etc. It is widely used in various power systems, mainly for the reliable operation of power systems.
structure
The bus duct is a commonly used connector in the power system, it is also known as the bus bracket, which is mainly composed of the bus bracket itself, the support bolts on the bracket, the connecting bolts on the bracket, the support bracket on the bracket, the support pad on the bracket, the support piece on the bracket, the bolt on the bracket and the protective pad on the bracket. The bus bracket is mainly used to connect the bus to important equipment such as substations, overhead lines, transformers, circuit breakers, etc., so as to realize the reliable operation of the power system.
raw material
The raw materials of bus duct are mainly stainless steel, plastic, aluminum alloy, cast iron, etc. Stainless steel bus duct has the advantages of high corrosion resistance, high strength, compact structure, light weight, low pollution to the environment, simple device, good protection performance, etc., so it is widely used in power systems. Plastic busway is also widely used in power system due to its excellent wear resistance, heat resistance, moisture resistance, durability, high tensile strength, light weight, and ease of installation.
apply
Busway is widely used in the power system, which can effectively connect the bus to substations, overhead lines, transformers, circuit breakers and other important equipment, so as to achieve the reliable operation of the power system. In addition, busway can be used for installation cables in order to connect cables to substations, overhead lines, transformers, circuit breakers and other important equipment.
device
The device of the bus duct is generally divided into two processes: first, the bus bracket should be installed, and the device orientation of the bracket should be consistent with the wiring direction of the bus bar; It is not necessary to install the busbar, and when installing the bus, it is necessary to pay attention to the device of the bus bar and the device of the bracket to ensure that the bus bar can be firmly fixed on the bracket.
Precautions
When using the bus duct, it should be noted that: pay attention to the device orientation of the bus duct, and ensure that the device orientation of the bus duct is consistent with the wiring orientation of the bus; It is necessary to pay attention to the bolt device of the bus duct, and ensure that the bolt device of the bus duct is strong to ensure the strong connection of the bus bar; It is necessary to pay attention to the inspection of the bus duct, and regularly check the device status of the bus duct to ensure the normal operation of the bus duct.
In short, the bus duct is an important connector in the power system, which can connect the bus to the substation, overhead lines, transformers, circuit breakers and other important equipment, so as to achieve the reliable operation of the power system. Therefore, when using the bus duct, we should pay attention to the device orientation of the bus duct, the device of the bolt and the view of the bus duct.
