Second, the scope is suitable for the low-voltage distribution room distribution cabinet, and the control cabinet of each equipment shall be implemented with reference to the relevant provisions according to the specific situation. Third, the responsibility of the mechanical and electrical installation and maintenance engineering department maintenance team every six months ...

1. Preparation First of all, the user should be notified to organize the cabinet without affecting the normal operation of the user. Then, according to the topology of the network, the existing equipment, the number of users, the user group and other factors, the wiring diagram and equipment inside the cabinet are outlined.

1. External force damage. Judging from the operation analysis in recent years, especially in Haipu East, which is developing rapidly, a considerable number of cable failures are caused by mechanical damage. For example, the cable laying and installation is not standardized, which is easy to cause mechanical damage; Engage in civil engineering on directly buried cables ...

The "Eastern Data and Western Computing" project aims to promote the rational layout of data centers, optimize supply and demand, green intensification and interconnection, so that the computing resources in the west can more fully support the computing of data in the east and better empower the country's digital development. 　　IT infrastructure is an important ...

In terms of structure, there are two ways to classify sheet metal cabinets: According to the division of the cabinet frame, it can be divided into the whole plate type and the column and beam combination type; According to the way of cabinet angle connection, it can be divided into four forms: adhesive connection, screw connection, pin connection and welded connection. ...

1. The network cabinet distribution frame is fixed in place, the panel paper is loaded into the distribution frame on the front, and the tray is installed on the back. 2. Positioning of the cable management board, the direction of the cable management board should be determined before threading when positioning the cable management board, so that the cable management board does not need to twist the direction in the process of line management, and it can enter the ...

11. What is the definition and classification of secondary circuits? Answer: The secondary circuit is used to monitor the measuring instrument, control the operation signal, all the low-voltage circuits of the relay and automatic devices are called the secondary circuit, and the secondary circuit can be divided into (1) current circuit according to the power supply and use; (2) Electricity ...

1. The circuit breaker cannot be closed Causes: 1. The undervoltage coil does not work (the voltage is normal). Solution: Replace the undervoltage coil. 2. Press the closing button, and the closing coil will not work when it is powered up. Solution: Replace the undervoltage coil. 3. Cooperation...

1. Energy saving The inverter technology can automatically adjust the refrigeration and heating power according to the indoor temperature change, and the power consumption is only 1/3 of the traditional air conditioner, which can save more than 30% of the electricity cost; At the same time, it has a dehumidification function, and it can also keep the indoor air dry when used in a humid environment. OK...

1. Conductor It is the main component of the product to play its use function, and it is to transmit electricity or information, that is, to transmit electric current or electromagnetic waves on the conductor. The conductor is the basic and indispensable main component of the product for the transmission of electric current or electromagnetic wave information. 2. Insulation ...

First of all, the number of the control cable often starts with the letter "C", which indicates that the control cable is specially designed to connect different sensors and control devices as a medium for signal transmission. This cable can transmit data signals and has a certain resistance to wear and chemical corrosion, so ...

1. What is TT, IN, IT system? A: The TT method refers to a protection system that directly grounds the metal shell of electrical equipment, which is called a protective grounding system, also known as a TT system. The TN method is a protection system that connects the metal shell of the electrical equipment with the working neutral line, called ...

What are the main parameters of the transformer? Answer: (1) rated voltage; (2) Rated current; (3) Rated capacity; (4) No-load current; (5) No-load loss; (6) Short-circuit loss; (7) Impedance voltage; (8) Winding connection diagram, phasor diagram and ...
