This is conducive to finding the manufacturer in time when problems occur during the use of wires, and consumers must pay attention to this when purchasing wires. At the same time consume ...

Power system The wire and cable products used in the power system mainly include overhead bare wires, busbars (busbars), power cables (plastic cables, oil-paper power cables (basically replaced by plastic power cables), rubber cables, overhead insulated cables), branch cables (replacing part of the busbars) ...

1. The Rittal air conditioner does not start when it is turned on, and the A17 is faulty. Check that the power supply voltage is 220V, normal; Detect that the battery voltage of the remote control is 3V, which is normal; Measure the fuse resistance value of the air conditioner compressor with a multimeter as infinity, which is normal. 2. The Rittal air conditioner does not start when it is turned on, and the display is not started.

1. The cabinet and chassis products provide space for power supplies, motherboards, various expansion boards, floppy disk drives, optical disk drives, hard disk drives and other storage devices, and these spare parts are firmly fixed through the internal supports, brackets, various chassis screws or clips and other connectors inside the cabinet and chassis.

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. ...

1. Filter maintenance of the indoor unit: The filter screen of the indoor unit generally needs to be replaced once every two months. It is not recommended to continue to use it after rinsing, because the rinsed filter is easy to stick, so that ventilation and ventilation are not smooth, and air circulation is affected. So if it's a one-off, direct replacement, not ...

First, the waterfall shape This is one of the older wiring patterns that can sometimes be seen. It adopts the artistic image of "Huaguo Mountain Water Curtain Cave", and directly hangs the twisted pair from the module of the patch panel, and there is a very beautiful sense of hierarchy when it is neatly distributed (24-48 per layer).

What are the conditions that must be met for high-voltage appliances? A: A. The insulation is safe and reliable; B. Long-term operation under rated current and certain short-term overload capacity; C. Able to carry the thermal and electrodynamic effects of short-circuit currents without damage; D. Switching electrical appliances can be safe...

Classified by voltage level According to the voltage level, it can be divided into medium and low voltage power cables (35 thousand volts and below), high-voltage cables (above 110 thousand volts), ultra-high voltage cables (275-800 thousand volts) and ultra-high voltage cables (1000 thousand volts and above). In addition, it can also be divided into AC ...

In recent years, with the accelerated development of China's informatization process and the continuous expansion of its scale, the demand for digital centers, as the carrier of the digital economy, is also increasing day by day. The operation of the digital center needs the support of a stable and energy-saving power system.

What is a protective relay? Answer: It can reflect the failure or abnormal operation of electrical equipment in the power system, and act on the device that trips the switch or sends out a signal. What are the commonly used relays? A: Current Relay, Voltage Relay, Signal ...

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 ...

How to make it simpler? How can safety be paramount? Still worried about not being able to reduce the cost of the system? The most suitable cabinet system is just a dream? You've got you covered – faster, safer, simpler, compatible, and versatile...

How much is the external design of domestic power distribution equipment products? Answer: Front panel type, cabinet type and box type, but also indoor type, fixed type and component fixed assembly, some products use drawer cabinets. Transmission circuits? Answer: Erected in the power plant step-up substation and ground ...

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 ...

The Rittal cabinet principle Rittal is a Germany company that specializes in the manufacture of all kinds of cabinets. It is famous for its reasonable design and guaranteed quality. Now there are many imitations in China, and imitation Rittal is also popular. The working principle of the Rittal cabinet is to cut off the inrush current of the wire itself.

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. Cabinets are generally divided into server cabinets, network machines, etc.
