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.

Bus, transformer, generator set unit wiring. It has the characteristics of simple wiring, less switchgear, easy operation, suitable for expansion, and because there is no generator outlet voltage bus, the short-circuit current of the low-voltage side of the generator and the main transformer is reduced. ...

Due to the long delivery time of the Wiener melt core, whether the Wiener fuse can be replaced by Siemens' fuse, the answer is yes, so it is recommended to use Siemens' Rong Xin, which corresponds to the following 3NA38012C NH-Fuse NH-,00(0 ...

1. The standard scale of the bus duct This specification regulates the terminology, skill requirements and test methods of the insulated bus trunk system (bus duct) and its plug-in feed box (hereinafter referred to as the feed box). This specification specification applies to additional voltage AC to 660V...

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. Selection of qualified products of regular enterprises: The busway must be a product with the 3C necessary certification mark and style test report. China's busway factories are uneven, and most of the production methods are handicraft, mainly in well-off areas. When purchasing, it is necessary to thoroughly investigate the production of the factory ...

The 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. The role of the busbar is to gather, distribute and transmit electrical energy. ...

1. The use status of bus maintenance on the low-voltage side According to the national standard "Code for Relay Maintenance and Automatic Equipment Design of Power Equipment" (GB50062-92): about the 3-10kV bus and the double bus running in parallel of the power plant and the primary substation, as long as the following conditions are installed.

Before the closed busway device, it should be ensured that the electrical shaft, the transformer and distribution room, the decoration project of the place through which the busway passes, and the heating and ventilation project are all completed to ensure that the closed busway 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. ...

1. Charging to the bus should be carried out with a switch (bus tie, bypass or line switch) with snap-action maintenance that reflects various types of faults. Before charging the bus, it should be considered whether the system may be unstable if the charging bus trips, and if necessary, the active power flow of the relevant line can be reduced. ...

Bar switches are different from regular switches. They are critical to ensuring effectiveness. For example, when the current exceeds a certain amount of time, they cause heat to be generated, allowing the fuse to switch the fuse to further assist in breaking the circuit. Therefore, as a kind of current protection device, they can achieve ...

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.

Busway is a conductive equipment used for current transmission, and now the higher the building is built, the more the application of busway is required, and in many large foremen, the use of busway is also very economical and reasonable. Any machine is made up of different parts, then the busway is made up of ...

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. ...

Compared with other air-type busway, Wiener closed busway has many similarities in appearance, and its difference lies mainly in the shell, the structure of the closed busway is more distinctive, which also makes its use have certain advantages. As long as it is in contrast ...
