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. ...

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) General bus duct Non-flame retardant and non-fire-resistant bus duct used in general load power distribution. In the event of a fire during a short circuit, it will always incinerate to other connected busbars, which may briefly cause fire accidents. (2) Flame retardant bus duct ...

In order to ensure the safe and economical operation of the power system and its power generation, supply and electrical equipment, power grid users require the voltage to operate in three ways: forward voltage regulation, reverse voltage regulation and constant voltage regulation. However, when the power grid is in practice, due to the change of active and reactive power output, the increase or decrease of electricity load, and the system wiring party...

The principle of the fuse is to use the current to flow through the conductor to heat the conductor, and the conductor is ablated after reaching the melting point of the conductor, so the electrical appliances and circuits used for circuit maintenance are not burned out. It is an accumulation of heat, so it is also able to complete overload maintenance. Once...

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. 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 ...

1. Commonly used busbars, useful categories Busbars are divided into hard busbars and soft busbars. According to its different shapes, hard buses can be divided into: rectangular busbars, tubular busbars, trough busbars, diamond busbars and so on. Rectangular busbars are the most commonly used busbars and are also busbars. According to its material ...

One of the characteristics of low-voltage switchgear is the multi-functional busbar system. The bus bar is a conductor that connects large electrical equipment such as generators and transformers with various electrical equipment. The role of the bus is to, sub-...

The advantage of the busway is that its structural design is simple, it is composed of metal plates, which can connect the circuits together, so as to achieve the safe and reliable transmission of electric energy. In addition, its structural design can effectively assist in reducing the occurrence of short circuits, reducing heat loss, and can effectively ensure the power ...

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. 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.

Generally speaking, plug-in busway is mainly used for power transmission. We know that all conductors will have losses, and the losses caused by the flow of electricity through conductors are larger and some are smaller. For example, compared with the aluminum wire with the same wire diameter and the copper wire, the loss of aluminum is larger, and the loss of copper is smaller. That is, the conductivity ...

When users use the distribution cabinet, they must understand the circuit device of the busbar, and many users are not very well understood, so let's talk about the bus connection mode of the distribution cabinet. The bus bar is used for the internal and external electrical appliances of the distribution cabinet.

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...

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...

(1) Single bus wiring. Single bus wiring has the advantages of simplicity and clarity, less equipment, less investment, and convenient operation and expansion, but its reliability and activity are poor. When the bus or bus separator is faulty or overhauled, all power to the bus must be disconnected. ...

The difference between busbar and cable The busbar is used to gather current. Many power and power supply circuits are connected to the bus, through which the power is gathered and sent to each circuit. Therefore, the current carrying capacity of the bus bar is relatively large, and the current carrying capacity of the bus ...

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. ...
