Closing faults can be divided into electrical faults and mechanical faults. There are two types of closing methods: manual and electric. Failure to close manually is generally a mechanical failure. Manual can be closed, electric can not close is an electrical fault. 1. Protection action: The protection action has been analyzed in front to trip the switch. ...

What are the principles for drawing and reading the schematic diagram of electrical control circuits? Answer: A. The schematic diagram is generally divided into power supply circuit, main circuit, control circuit, signal circuit and lighting circuit. B. In the schematic diagram, the position of the contacts of each electrical appliance is according to the ...

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 kind of cable can transmit data signals, and has a certain resistance to wear and chemical corrosion, so it is widely ...

Short-circuit fault: There are two-phase short circuits and three-phase short circuits, which are mostly caused by hidden dangers left in the manufacturing process. Grounding fault: one or more cores of the cable break down to the ground, and the insulation resistance is lower than 10kΩ is called low-resistance grounding, and higher than 10kΩ is called high-resistance grounding. Mainly due to cable corrosion, lead ...

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 ...

The conductor is the basic and indispensable main component of the product for the transmission of electric current or electromagnetic wave information. 2. Insulation ...

1. It should have good technical performance. The structure of the cabinet should be designed according to the electrical and mechanical properties of the equipment and the requirements of the use environment, so as to ensure that the structure of the cabinet has good stiffness and strength, as well as good electromagnetic isolation, grounding, noise isolation, ...

External damage: In the process of storage, transportation, laying and operation of cables, they may suffer external damage, especially the directly buried cables that have been run, and are prone to damage in the ground construction of other projects. Such accidents often account for 50% of cable accidents. In order to avoid such accidents, in addition to strengthening the cable ...

Server cabinets have requirements in terms of depth, height, and load-bearing capacity. There are three heights of 2.0 meters, 1.8 meters and 1.6 meters; The width is 800mm, 700mm or 600mm; There are three depths: 700mm, 800mm and 900mm. Can be configured: special fixed pallet, special ...

1. Tie the cable tie at the beginning of the root of the cable with a cable tie, if there are too many cables, the number of the network cable is divided into two or many parts from the center, but the demand ensures that each part of the network cable is connected, because the next step is simple. 2. According to ...

As a commonly used box in Rittal, many users do not understand the material and structure of this series of boxes. Now I would like to introduce the Rittal explosion-proof enclosure Apply: – Zones 1 and 2 or Zones 21 and 22 according to 94/9/EG – Ambient temperature range: -30°C.

1. Power failure: The power supply of the fan fails, such as the power cord is disconnected, the power plug is loose, etc., which will cause the current to fail to transmit normally, resulting in the fan stopping and rotating. 2. The temperature is too low: Some heat dissipation windbreakers have a temperature protection function, when the temperature is too low, the fan will automatically ...

1. The cabinet is generally made of cold-rolled steel plate or alloy to store the computer and related control equipment, which can provide protection for the storage equipment, shield electromagnetic interference, arrange the equipment in an orderly and neat manner, and facilitate the maintenance of the equipment in the future.
