1. Look at the packaging, the wires of the national standard are often better, neat, and have a sense of quality when you hold them. 2. To open the package and take a look at the wires inside, the wire requirements of the national standard wire 1.5——-6 square are required to be skin thickness (insulation thickness) is 0.7mm, and too thick is non-standard.

Five details that are easy to overlook: One of the hidden details: steel The most basic thing of a cabinet is to look at the steel, the Rittal standard cabinet is made of section steel, there are many masters who understand the cabinet to understand, the steel plate must be thick, just knock it with your fingers. General ...

We know that electronic and electrical equipment is installed in the electrical cabinet, in fact, there are working temperature requirements, the general storage temperature can not be lower than minus 25 degrees, the working temperature can not be lower than minus 20 degrees, but now the outdoor temperature in the north is very simple to reach the lower limit of this working temperature, this time heating ...

Why use transformers to measure high voltage and high currents? Answer: (1) Expand the scope of use of the instrument. As long as the transformer with different transformer ratios and converter ratios is used in conjunction with a voltmeter with a full voltage of 100V and an ammeter with a full current of 5A, it will be ...

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 ...

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 "Eastern Data and Western Computing" project aims to promote the rational layout of data centers, optimize supply and demand, green intensification and interconnection, so that the computing resources in the west can more fully support the computing of data in the east and better empower the country's digital development. 　　IT infrastructure is an important ...

One. The nature is different Distribution box: There is a large amount of parameter data in the distribution box. It generally constitutes a low-voltage distribution box. Control cabinet: The control cabinet is to assemble the switch cabinet, measuring instruments, protection devices and auxiliary equipment in a closed or semi-enclosed metal cabinet or screen according to the requirements of electrical wiring.

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. When the electrical cabinet is used, the shell should be reliably grounded, and the electrical parts should be comprehensively inspected to eliminate the phenomenon of leakage and open circuit that may be caused by long-distance transportation, and check whether the voltage is consistent with the working voltage. 2. The electric cabinet is a non-explosion-proof oven, so it is flammable, explosive, volatile and corrosive.

What are the main parameters of the transformer? Answer: (1) rated voltage; (2) Rated current; (3) Rated capacity; (4) No-load current; (5) No-load loss; (6) Short-circuit loss; (7) Impedance voltage; (8) Winding connection diagram, phasor diagram and ...
