1. The main bus at the upper end of the low-voltage distribution cabinet is calculated according to the material and cross-section in the extension meter. The bus bar connected to the main bus at the upper end of the switch is not accounted for and is included in the low-voltage distribution cabinet. 2. The transformer mainly depends on how large the load is, according to your switchgear can be calculated to match the transformer, but not the same...

The modulus of the bus system is 40mm, 60ram, 100/185mm; The bus cross-section is rectangular, double "T" (i.e., "H" shape) and three "T" (i.e., 'state') shapes; The bus system can be three-wire, four-wire or five-wire, or even seven-wire, of course, it should be determined according to the needs ...

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) Single bus wiring. Single bus wiring has the advantages of simple and clear, less equipment, small investment, convenient operation and conducive to expansion, but the reliability and flexibility are poor. When there is a fault or maintenance of the bus bar or bus barrier switch, the full power supply of the bus must be disconnected. ...

The Wiener bus system is a standardized system for bus spacing, which is used in low-voltage power supply and distribution switchgear, so that the bus can both conduct electricity and support electrical components. The system is divided into 40, 60, 100 and 185mm systems. ...

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 ...

If the temperature of the dense busway is too high, a fault will occur. For the sake of insurance, it is necessary to know the heat dissipation method of the densely packed busway to prevent the impact of excessive temperature on the busway. Low-voltage transmission line conductors, wires, cables, branch dense busway, exposed conductive poles, punctured ...

When the busway has not been developed and introduced, the cable is still an indispensable figure in the low-voltage power distribution system, when the busway system is introduced and widely used. Whether to choose the cable or the bus duct has become a topic of endless debate. ...

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.

The novelty, flexibility and originality of the busbar device appliance. It indicates the vitality of this skill and its broad market prospects. This is the real reason why we pay attention to it. First of all, this small electrical appliance set ...

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 bus system is a system with standardized bus distance, which is used in low-voltage power supply and distribution switchgear and control equipment, so that the bus can play the effect of conducting electricity and supporting electrical components. The system is divided into 40, 60, 100 and 185mm ...

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 ...

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. In addition, customized busbar equipment allows the busbar system to be routed around obstacles ...
