Rittal Cables – an introduction to the performance of industrial control cables

1. The air conditioner displays the H1 fault code - the reason When the outdoor temperature is low and the humidity is high, the heat exchanger of the outdoor unit will be frosted after the air conditioner runs for a period of time, then the automatic defrost function will be activated, and the heating operation will be temporarily stopped for 5-10 minutes. Air conditioner heating defrost shows H1 which is normal ...

It can also be used to regulate temperature and humidity in small spaces. Outdoor unit: suitable for outdoor general base station, outdoor ...

1. GGD AC low-voltage distribution cabinet has the characteristics of high breaking capacity, good dynamic and thermal stability, flexible electrical scheme, convenient combination, seriality, strong practicability, novel structure and high protection level. It can be used as a replacement product for low-voltage switchgear. Structural features ...

What is a substation? A: It is a power supply hub that receives electrical energy from the power system, transforms (boosts or downgrades), and then distributes the power. What is the main role of transformers in the power system? Answer: The main function is to convert the voltage to facilitate ...

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. 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.

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 ...

The control cabinet is according to the requirements of electrical wiring to assemble switchgear, measuring appearance, maintenance appliances and auxiliary equipment in a closed or semi-closed metal cabinet or screen panel, and its arrangement should meet the requirements of the normal operation of the power system, easy to overhaul, and not to endanger the safety of people and surrounding equipment. Normal operation ...

1. Avoid light The server is required to operate in a constant temperature environment, and direct sunlight will increase the temperature in the computer room, which will damage the display and shorten its service life. When operating in IDC and ISP data centers, it is impossible to see a ray of sunshine. So, in ...

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 ...

1. It is not displayed at that time. Solution: Check whether the sample signal cable is not connected. 2. Whether the fuse core of the controller in the cabinet is burned out. Solution: Remove the burned out fuse core and replace it with a new one. 3. The voltage of the distribution cabinet is too high, and the overvoltage alarm. Workaround: Re...

1. Site selection. The location of the low-voltage distribution room should be close to the load center, set up in a place with less dust, less corrosive medium, dry and slight vibration, and should appropriately leave room for development; Second, the layout of power distribution equipment. The layout of the distribution equipment in the low-voltage distribution room must follow the principle of safety, safety, and safety.

1. The elevation or verticality of the distribution box (panel) exceeds the allowable deviation: it is caused by inaccurate measurement and positioning or uneven ground, and should be corrected in time. 2. The iron frame of the distribution box is not square: the iron frame is not straightened and aligned before the installation of the iron frame, or the position of the fixed point is deviated during installation.

Now AI has been widely used in many fields, and while we enjoy the convenience brought by AI skills, we should also know that behind these AI skills are a huge amount of data processing and communication by weak servers, and then find the most efficient solutions.

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...

1. Check whether the filter screen of the Rittal air conditioner is blocked, if it is blocked, clean the lower filter in time. 2. Check whether there is any remaining freon in Rittal air conditioner, and if not, inform the professional maintenance personnel of the air conditioner to add fluoride in time. 3. Check the function of Rittal air conditioner.

Rittal Riline Compact is a proven solution for compact power distribution systems for enclosures and small control cabinets, which is used in plant control systems in industries such as automotive, rubber, packaging machinery and renewable energies. All along, RiLin...

1. Judgment and treatment of sudden tripping fault of high-voltage switchgear during operation 1) Fault phenomenon: The cause of this failure is the protection action. The high-voltage cabinet is equipped with protection against overcurrent, quick cut-off, gas and temperature. 2) Judgment method: judging the cause of the fault can be based on the relay off, remote ...

Usage code - not marked as power cable, K- (control cable), P- (signal cable); Conductor material code - not marked as copper (can also be marked as CU), L- (aluminum); Inner Sheath Code – Q-(Lead Packed), L- (Aluminum Cladding), H- (Rubber Jacket), V-(Polyvinyl Chloride ...
