A detailed description of the Wiener comb busbar and connection terminals

There are three types of maintenance commonly used in medium and low voltage bus systems: (1) Transformer backup overcurrent maintenance (typical maintenance action time is 1.2s - 1.4s) (2) Transformer voltage with feeder quick-break maintenance locking ...

1. Select the type of fuse according to the line requirements and installation 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. ...

Precautions for the device VDE 0660 Specification Section 107 / EN 60947-3 Specification / IEC 60947-3 Specification 3 poles are broken at the same time, double breakpoints. Operator-independent, safe opening/closing, in position ...

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 ...

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.

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...

1. It has a modern beauty; 2. Small dimensions; 3. Strong and light weight, simple operation; 4. The connection is very simple (just like connecting water pipes, connecting sections through tees, elbows and other joints to make them into a system; ...

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.

1. The fastening wiring force should be moderate, avoid sliding the bolts and nuts with excessive force, and replace the bolts and nuts that have been slid in time, and prohibit the operation. 2. When tightening or loosening the screws with a screwdriver, it is necessary to force the screws to ...

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.

Phase-off bus is a kind of high-current transmission equipment widely used in the outgoing circuit of generators of 50MW and above and the branch circuit of the factory The phase-off busbar, conductor and shell are made of aluminum plate coil and welding, with the following characteristics: ...

The nature is different Busbar: It is a common path on which multiple devices are connected in the form of side-by-side branches. Busway: It is a closed metal equipment composed of copper and aluminum busbars. Different uses Mother...

(1) Single bus wiring. Single bus wiring has the advantages of simple and clear, less equipment, less investment, convenient operation and expansion, but its reliability and activity are poor. When the bus or bus divider is faulty or overhauled, it is necessary to disconnect all power to the bus. ...

1. Before welding, it is necessary to check whether the welding equipment is defective, whether the grounding of the electrical equipment is reliable, and strictly abide by the "welder safety operation procedures" when welding. 2. Correct wires and busbars, and prohibit the use of handleless files. ...

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...

Compared with other air-type busway, Wiener closed busway has many similarities in appearance, and its difference lies mainly in the shell, the structure of the closed busway is more distinctive, which also makes its use have certain advantages. As long as it is in contrast ...

(1) Air-type busway Since the mid-50s of the last century, represented by Beijing Baizhifang Airport Electrical Appliance Factory, the conductive row has been supported in the shell with insulating liner and insulated by air medium. The phase-to-phase distance is 50mm. (2) Secret ...

The communication and connection skills of the independent power supply system create better prospects for the power supply of the future.
