Circuits with small capacity are semi-enclosed or enclosed without fillers; The selection of large short-circuit current has a packing closed type; Semiconductor component maintenance selection of quick fuses. ...

Cause of bus failure 1. The internal network of bus insulators and breaker sleeves caused by surface pollution 2. The voltage transformer installed on the bus and the current transformer between the bus and the circuit breaker are faulty 3. The support of the circuit breaker or isolation switch caused by the reverse operation ...

According to the requirements of the relevant specifications, the placement of the three-phase busbar can be roughly divided into two kinds according to the model of the low-voltage distribution cabinet and the different manufacturers: horizontal placement and placement of the down wire, according to the order of placement.

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 for our attention. First of all, this small electrical appliance plant was conceived ...

The bus system plays a very important role in the practice of construction, and for products such as the bus system, the relevant items can not be ignored, so that we can better use the practical value of this type of product. Generally speaking, when we are purchasing a bus system ...

Single bus wiring method: all outgoing wires are connected to the same busbar, which is also the most cost-effective and simplest wiring method Single bus segmentation: The outgoing line is arranged in two parts on different sections of the single busbar, so that a power failure in the meantime does not affect the power supply of the other bus ...

The power supply trunk of modern buildings plays a very important role like the aorta of the human body, and if something goes wrong, it can cause serious consequences. In the 80s of the 20th century, many stable cables were used in modern buildings. With the rapid development of the city, the power load of the building ...

1. Trunk power distribution system, simple wiring and reliable operation. 2. It is convenient to tap, and you can tap without cutting off the main power supply. Large power supply capacity up to 6300A current-carrying capacity. 3. High dielectric strength, strong overload, superior fire performance. Good heat dissipation performance, low impedance ...

1. Select the model of the fuse according to the circuit requirements and device conditions. Circuits with small capacity are semi-enclosed or enclosed without fillers; The selection of large short-circuit current has a packing closed type; Semiconductor component maintenance selection of quick fuses. ...

The busbar and busway are actually one open and one closed, and the other is not closed. The closed busway is referred to as the busway, that is, the busway is sealed The closure of the busbar, the closure of the busbar and the busway all refer to the same east...

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 it comes to cable tray installation, wiring is not very convenient. This phenomenon can be avoided by using busway. The 5 advantages of using busway in the cable tray device are as follows: 1. Convenient connection of bus duct: the so-called plug-in bus duct, fireproof bridge is the way it uses plugged in.

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 ...

(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 moment, 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 smaller one, so as to facilitate the bus tie circuit breaker when there is a problem, the bus tie circuit breaker can quickly trip, cut ...

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...

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: 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.

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.

The bus system is to directly connect the components to the bus, the bus does not need to be perforated, at this time, the bus is not only the conductor of the component, but also the support of the component, the current can reach 2500A, so that the box transformer function has the following progress: 1 ...

Bus line refers to a product made of copper (copper bar) and aluminum material with high conductivity to transmit electrical energy and have the ability to collect and distribute electricity. The main conductor used by the power station or substation to transmit electrical energy. Through it, the output of the generator, transformer or rectifier ...
