The appearance of the instrument plays a very important role in the air separation equipment and gas purification process, and it is indispensable for the adjustment of the air separation process and the detection of product quality. Because there are different types of online profiling surfaces for monitoring different gas medium targets at each stage of the air separation process, the operating conditions in the fractionation column can be understood through the output signal of the dissected surface, and the process can be controlled to produce 02, N2, AR and cryogenic liquids with qualified purity and output value requirements under the best working conditions, and can also ensure whether the high-purity gas meets the quality standards after purification.
Therefore, in the production process of gas and cryogenic liquid products in the air separation plant, it is necessary to accurately quantify and strictly control the composition of the gas components at each stage of the process, and at the same time, the content of hydrocarbons (full hydrocarbons and non-full hydrocarbons) in the main condenser and other parts of the air separation tower is automatically and continuously detected by using online chromatography, which is an indispensable part of explosion-proof and safe production in the air separation plant.
For this purpose, it is necessary to reach and fulfill the following tasks in the selection and analysis of the appearance of the instrument:
1. Monitor the purity of the process gas in the process to meet the gas purity requirements of each process section;
2. Through the output data of the online analysis of the appearance of the instrument, the change of the working conditions of each process can be reflected and grasped in time;
3. The process working conditions can be adjusted to work in the best state;
4. Ensure and control the purity of gas products and cryogenic liquid products produced under safe working conditions, meet the quality requirements, and meet the national standards;
5. The analysis of purified high-purity gas impurity components can meet the requirements of national standards.

Is there a restriction on the installation direction when Schneider installs the inverter?
It should be basically stored in the plate, the problem is that the plate with a fully enclosed structure is large in size, takes up a lot of space, and the cost is higher. This can be done by:
(1) The planning of the disc should be based on the heat dissipation required by the actual device;
(2) Profit ...

Inverter braking resistor selection – Schneider
In the process of fast parking, because of the inertia, a lot of regenerative electric energy will occur, which will directly act on the intermediate DC part of the inverter, and if this part of the electric energy is not consumed, the inverter will be faulty or the inverter will be damaged. The braking resistor is used to dissipate this part of the electrical energy. ...

The difference between the highest frequency and the basic frequency of the inverter - Schneider
1. There are two ways to say the fundamental frequency:
(1) The frequency corresponding to the maximum output voltage of the inverter is called the fundamental frequency;
(2) When the output voltage of the inverter is equal to the additional voltage, the minimum output frequency is called the fundamental frequency. The fundamental frequency is expressed in fBA.

Four-pole switches need a scene – Schneider
(1) It is necessary to choose a four-pole switch:
For the sake of repair safety: in the TT grounding system, the total equipotential bonding is done on the user side, but because the total equipotential bonding at this moment does not include the neutral wire, the line fault (for example: a phase wire grounding) occurs on the grounding electrode on the power supply side.
