185Power - The solution for the 185mm busbar system

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...

When multiple inverters are used in the common DC bus, because the DC bus between the inverters is connected together, the bus energy between the inverter in the power generation operation state and the inverter in the electric operation state can flow to each other, so that the voltage of the common bus remains relatively stable, and the body ...

The bus PT is used to measure the bus voltage on the high-voltage side of the main transformer, and is used to assist in grid connection. Before starting the synchronous grid connection, the excitation system actively adjusts the terminal voltage according to the bus voltage measured by the bus PT, so that the voltage on both sides of the grid-connected switch is basically equal, which is convenient for the same period of grid connection. ...

1: The overhaul should start from the low voltage side of the transformer. After the power failure of the low-voltage cabinet, clean the dust in the cabinet to check whether the connection between the bus bar and the down conductor is outstanding, whether the connection is heated or discolored, whether the cable head and the terminal pile head are strong and reliable, whether the grounding wire is corroded, and whether the terminal pile head is tightened. Everything secondary ...

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. ...

The arc of the switchgear cable spacing causes the pressure and temperature in the switchgear to increase rapidly, and if not removed in time, it will cause serious harm in the following aspects: (1) The arc temperature is 2 times the appropriate solar temperature, and the large ...

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., ...

1. The conductor of the bus bar is a high conductivity TMY electrical hard copper bar rolled by T2 electrolytic copper, and the purity of copper must be ≥ 99.95%, and copper-aluminum alloy or other mixed alloy non-pure copper conductor materials shall not be used, and the copper plate is tin plated on the full length. 2. The raw material of the neutral wire and the phase wire in the bus system is the same.

1. Closed busbar hooking technology Circuit breakers and contactors can be hooked on the bus through the bus adapter, and fuse switches and other products are directly attached to the bus, so the bus bar plays a two-layer effect of conductive and fixed rotation.

　First, this kind of small electrical equipment is a novel concept, adopting the "non-hole lap technology", and the electrical equipment is directly installed on the confluence bus system to form a power distribution or control loop. The representative creations are busbar device fuses and fuse load disconnectors. ...

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. ...

(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 ...

If you understand the scope of application of the busway, you can see that the excellent effect of the busway has the upper hand, which has a lot to do with the structural features. Therefore, if you want to have more confidence with the bus duct, you still need to understand it from the structural characteristics. At a time when China's economy is developing rapidly, ...

XBT series mine flameproof communication cable distribution box has the characteristics of small size, reasonable cable import and export, and wide coverage. Each distribution box has 4-10 inlet and outlet bells, which is suitable for HUYV type mine signal cable in coal containing sexual gas (methane) mixture (non-mining face).

(1) For the charging of the spare bus, when there is a bus tie circuit breaker, the bus tie circuit breaker should be used to charge the spare bus. At this time, the maintenance device of the bus tie circuit breaker should be fully invested, and the relevant maintenance value and time limit should be changed to a small size, so that when there is a problem with the bus, the bus tie circuit breaker can be quickly tripped, cut off...

1. Busway horizontal device, the interval between the two brackets is ≯2500mm, and the interval between straight devices is ≯3600mm; 2. When the device bracket is straight, it should be drilled with the channel side plate and fastened with M6-M8 bolts. 3. In the process of installation construction, priority should be given to the power supply system, ...

In the industry, tubular bus bar can be described as one of the more common equipment, with high mechanical strength, good insulation, wide range of application and other characteristics of many enterprises. So do you know what are the ways to link tubular busbars? ...

The Wiener comb busbars and connection terminals are available with QUADRON®CrossLinkBreaker in size 000/00 Recommended installation: Wire entry at the lower end of the NH-fuse disconnector through the comb busbar. In the mounting position ...

The arc of the switchgear cable distance problem causes the pressure and temperature in the switchgear to increase quickly, and if not removed in time, it will form a major hazard in the following aspects: (1) The arc temperature is 2 times the appropriate solar temperature, and the large ...

1. The tubular bus is in the form of a split-phase fully insulated shielded copper tube bus. 2. The cylindrical capacitor structure is selected, and the voltage equalizing capacitor layer, the main insulation layer, and the bottom layer of the shielding street are set between the conductor and the insulating sheath, and the shielding grounding layer on the outside is connected to the grounding grid. The quantity of each layer is determined by the seller.
