What is eddy current? What are the harms of eddy currents? Answer: When an alternating current is passed through a wire, an alternating magnetic field is created around the wire. An induced current is generated inside the whole conductor in an alternating magnetic field, and because this induced current forms a closed loop inside the whole conductor, ...

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.

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.

1. Disconnect the power supply, check whether the rack of the control cabinet has reliable grounding, and make the grounding resistance not greater than 4Ω. 2. There are voltages of different properties on the control cabinet (DC 110V; Communication single-phase 220V; Three-phase communication), the circuit must be distinguished during maintenance to avoid short-circuit accidents.

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 ...

Complete set of electrical maintenance knowledge: 1. Low-voltage distribution cabinet 1. Regularly check whether there are traces of pest activity in each cabinet, and carry out trapping regularly. 2. Check whether the warning signs and maintenance signs are placed correctly. 3. Check whether the emergency tools and lamps are in order.

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 air conditioner shows 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, and then the automatic defrosting function will be activated, and the heating operation will be temporarily suspended for 5-10 minutes. Air conditioner heating defrost shows H1 which is normal ...

The construction of new infrastructure (new infrastructure) is a change in the upgrading and transformation of the industrial structure. As an important part of the new infrastructure, the data center provides a solid and extensive infrastructure guarantee for 5G, artificial intelligence, Internet of Things and other occupations. Rittal brings a new generation of infrastructure solutions ...

1. Once a month (8 hours at the end of the month), and make a maintenance record. 2. Clean the gears of the whole machine to ensure the cleanliness and normal clearance of the gears. 3. Check the gap between the two gears at the punching device of the processing department and adjust the clearance. 4. Adjust the gap between each ink roller to ensure that ...

RITTAL TS8 cabinet front door door rear sealing plate, a galvanized mounting plate 16-fold profile ISV-TS 8 cabinets with a maximum current of 1600 A single door Can be installed in all TS 8 cabinets of the same height and depth - Can be pre-installed in configurations - Available in the spirit ...

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. Safety: As the carrier of electrical equipment, the outdoor cabinet must have excellent structural design, solid materials, and firm bottom fixation to meet the requirements of strong typhoons, strong rainstorms, and even strong earthquakes. At the same time, the cabinet should have anti-leakage, anti-short circuit, anti-cut and other requirements. 2. Rainproof and dustproof ...

1. Built-in air conditioner for heat dissipation The cabinet is equipped with a refrigeration system, the evaporator and power devices are installed inside the cabinet in a closed manner, and the condenser and compressor are placed in the external circulation air duct or outside the cabinet. Since the power unit is sealed in the cabinet, as long as the appropriate sealant is used ...

Industrial wires and cables include single-core wires and cables, rubber cables, shielded control cables, flame-retardant cables, fire-resistant cables, etc. Single-core wire and cable It means that there is only one conductor in the insulation layer, the common BV wire, and B represents the wiring; V stands for insulating polyvinyl chloride. Suitable for AC ...

1. Set the target temperature: the default temperature of the original factory is 35°C, you can press and hold the set button for more than 1 second after starting, the parameters start to flash, complete the temperature adjustment by pressing the UP and DOWN buttons, and after adjusting to the target temperature, press the set button to store the set parameters. 2. High temperature alarm: ...

1. Improve the environment inside and outside the cabinet 1. We not only need to keep the electrical cabinet dry and clean, but also need to do a good job of cleaning and sanitation in the distribution room where the distribution cabinet is placed to prevent water and dust from entering the cabinet 2. The lighting environment of the distribution cabinet should be good, and it should be equipped with professional cabinet lighting ...

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 ...

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.
