Rittal enclosures – Q&A on the basics of high- and low-voltage distribution cabinets

If the indoor temperature is higher than the outdoor one, or the indoor temperature is higher than the set temperature, the air conditioner will not start; Solution: Test the temperature comparison between indoor and outdoor to check whether the indoor temperature is too high. The voltage of the air conditioner is unstable, and the compressor cannot be started normally.

The operating voltage of the cable Generally speaking, there is a certain relationship between the operating voltage of the cable and the rated voltage. If some cable lines are not in use, they must be connected to the power grid to ensure that the cable lines are not exposed to moisture. When the neutral point is not grounded ...

1. Maintenance content (1) Check the heat dissipation of the controller It is strictly forbidden to cover the controller with plastic or other materials; Leave enough space behind and on the sides of the controller (> 120mm); It is strictly forbidden to position the controller close to the heat source; It is strictly forbidden to put sundries on the top of the controller; Avoid over-the-top ...

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. 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. Core: The core is the conductive part of the power cable, which is used to transmit electric energy and is the main part of the power cable. 2. Insulation layer: The insulation layer is to electrically isolate the core from the ground and the cores of different phases to ensure the transmission of electric energy.

Big data is also a strategic industry related to the future development of the steel industry. In order to remain competitive in the long term, thyssenkrupp Steel in Germany is stepping up modernization and standardization in its production-related IT areas. The Rittal Container Data Centre is essential for the successful implementation of this upgrade.

The model of the power cable 1. Use the capitalization of the first letter of Hanyu Pinyin to indicate the type of insulation, conductor material, inner sheath material and structural characteristics. For example, Z is used to represent paper (zhi); L stands for Aluminum (LV); Q is for lead (qian); F stands for fen; ZR stands for Flame Retardant (zura...

The Rittal Configurator (RiCS) is a new system configurator for the Rittal system product. It will allow you to quickly select a custom-configured cabinet that meets your application needs. During the configuration process, you can view the configuration in real time through the visual 3D model. After the configuration is complete ...

1. Reliable quality assurance Choosing the right server and cabling cabinet is important, and the slightest negligence can lead to huge losses. No matter which brand of product it is, quality is the first thing that users should consider. 2. Load-bearing guarantee With...

1. A01 system message: open the cabinet door Rittal air conditioner Cause: the position of the door opening and closing is incorrect; 2. A02 system message: the temperature in the cabinet is too high: the refrigeration capacity is too low or small; 3. A03 System Message: Filter Monitoring Cause: Dirty Filter Diagnosis ...

Thermal function: Due to the existence of thermal expansion and contraction, we should also pay attention to the thermal function of industrial control cables, that is, the temperature resistance level of industrial control cables, the heating and heat dissipation characteristics of cables for power transmission at working temperatures, current carrying capacity, short circuit and overload capabilities, the thermal deformation and thermal impulse resistance of the constituent materials.

The power cable is used to transmit and distribute large-scale electrical energy in the main line of the power system, and the control cable directly transmits the electric energy from the distribution point of the power system to the power connection line of various electrical equipment and appliances. The rated voltage of power cables is generally 0.6/1KV and above, and the control cables are mainly 4 ...

Which electrical equipment must be grounded or zeroed? Answer: (1) The base and shell of generators, transformers, motors, high and low voltage electrical appliances and lighting appliances; (2) the secondary coil of the transformer; (3) the framework of the switchboard and the control panel; (4) Transmission device of electric equipment ...

(1) The cause of moisture in the cabinet 1) Environment shutdown. The ring main unit or the opening and closing station itself is a closed environment, because of the poor ventilation conditions, it is easy to gather moisture and generate condensation, and there are many large buildings today in order to reduce the occupied area, the opening and closing station, the power distribution room is built in the basement. Cause...

1. About the electrical part: 1. The input side and output side of the miniature circuit breaker are inverted. 2. The voltage of the coil of the electrical parts does not match the voltage of the drawing, especially the voltage of the small relay and indicator light is easy to error. 3. The positive and negative polarity of electrical appliances is reversed, and the internal polarity of DC electrical appliances is reversed.

What is the material of the busbar? A: Copper busbar, aluminum busbar and steel busbar. What is the significance of busbar coloring? Answer: It can increase the radiation capacity, which is conducive to heat dissipation, and the allowable load current can be increased by 12-15% after coloring. ...
