Why the voltage between the two phase wires is 380V: First, let’s briefly talk about the line voltage and the phase voltage: the line voltage is the voltage between the live wire and the live wire, which is 380V, and the phase voltage is any one of the live wire and the middle of the three live wires. The voltage between the sex lines is 220V;

Copper nose is also called wire nose, copper wiring nose, copper tube nose, terminal block, etc. It is called differently in various places and industries. It is a connector used to connect wires and cables to electrical equipment. The top side is the fixed screw side, and the end is the copper core of the wire and cable after being stripped. Copper noses are used for wires larger than 10 square meters. Copper noses are not used for wires smaller than 10 square meters. Cold-pressed wire noses are used instead. The copper nose can be divided into tin-plated and non-tinned surface, pipe pressure type and oil blocking type.

With the continuous development of power grid distribution system, the power supply environment is becoming more and more complex. People's electricity standards and demand continue to rise, which has led to the popularization of low-voltage distribution lines in our country, which is related to people's lives and production, and requires timely renovation of low-voltage distribution cabinets. However, there are four problems in the transformation process. Let's understand them together.

The contactor is mainly composed of an electromagnet and a contact. The contactor with a larger capacity also has an arc extinguishing device. When the coil is not energized, the open contacts are called normally open contacts, and the closed contacts are called normally closed contacts. When the coil is energized, the electromagnet generates a suction force to attract the armature, so that the normally open contact is closed and the normally closed contact is disconnected. After the coil is de-energized, the electromagnet loses its attraction, the normally open contact is disconnected, and the normally closed contact is closed to realize the on-off of the circuit.

Overhead transmission lines are the main components of the power system and transmission network. It undertakes most of the industrial and domestic power transmission tasks and is also the most fault-prone part of the power system. The common faults are classified according to their nature, which are mainly divided into transient faults and permanent faults. The transient faults mainly include flashovers caused by lightning overvoltages and short circuits caused by birds. Permanent faults are mostly due to weather or the equipment itself. Causes such as icy weather or line aging caused by instantaneous overvoltage breakdown of transmission line insulation devices, equipment installation, storms, earthquakes and other problems caused by permanent short circuit of transmission lines. According to their specific categories, they can be divided into horizontal and vertical faults. The horizontal faults are mainly single-phase, two-phase and three-phase short circuits, and the longitudinal faults are mainly one-phase and two-phase disconnection problems. These faults can easily cause the transmission line to trip. Wait for accidents, so it is necessary to find out the cause of the failure as soon as the failure occurs, solve the problem in a targeted manner, or take preventive measures for a certain failure in advance.
