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 ...

The grounding of the DC system should include two situations: the one-point grounding of the DC system and the two-point grounding of the DC system. In the DC system, the positive and negative poles of the DC are insulated from the ground, and when the ground of one pole is generated, there is no grounding current due to the fact that there is no grounding current.

The busway system is an efficient power distribution device, especially suitable for the needs of high-rise buildings and large-scale factories for reasonable wiring. With the presentation of modern engineering equipment and equipment, the electricity consumption of all walks of life has increased rapidly, especially many high-rise buildings and large factories. Traditional cables serve as ...

1. The cable in and out of the bridge is not piping 2. The orientation of the bridge grounding and crossing is incorrect, and the special grounding line of the spray or painted bridge device is not equipped with a special disc gasket 3. The fireproof board of the electric well is not fixed, and the fireproof plugging is not perfect 4. The bridge is opened at will, and no standard accessories are used.

generatrix In the field of electricity, the busbar can also be called the busbar, busbar, etc., which mostly refers 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.

In today's information society, the computer room is a very common equipment, so the most important thing in a computer room is the bus system, which is the center and skeleton of the power distribution of the entire computer room. Then a reasonable bus system will greatly improve the efficiency of the equipment room. So how do you optimize ...

Densely insulated bus duct (hereinafter referred to as bus duct) can be communication three-phase three-wire, three-phase four-wire, three-phase five-wire system, frequency 50-60Hz, voltage to 400V, rated operating current of 250-5000A, mainly as a new type of power supply and distribution equipment in industrial and mining, enterprises and high-rise buildings. Mother with insertion day ...

1: The basic requirements for the bus duct: 1) Conductor data: high-purity electrical copper drawn from national standard T2 electrolytic copper, with a purity of more than 99.9% and a full-length tinned copper conductor. 2) Shell: Select high-quality aluminum-magnesium alloy profiles that meet the strength, with heat dissipation ribs, and the appearance should be oxygen-proof.

Introduction to the performance of low-voltage bus system: 1. The bus bar is not perforated, and is connected with the cable and copper bar through the connection clip or terminal 2. Switches, contactors and other electrical components can be directly hung on the bus through adapters 3. Save ...

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 ...

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. ...

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. 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.

What is a tubular busbar Tubular bus bar is a kind of bus bar product with copper tube or aluminum alloy tube as conductor and external insulation. The tubular bus has the characteristics of high current (12000A), high mechanical strength, good insulation, wide application range, etc., ...

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 ...
