The role of small air separation unit dcs system

The role of small air separation unit dcs system
Grounding is to achieve a low impedance link between the circuit, the Danyun, and the first-class point or the equipotential surface that is used as the common reference point of the signal. The grounding of the dcs system is to ensure that when the signal entering the dcs system, the power supply or the equipment of the dcs system has a problem, the effective grounding system can withstand the overload current and can quickly lead the overload current to the ground.

Adsorption and purification of air
Dec 13, 2024
When the general motor in the air separation plant is started, the current that the stator of the motor takes from the power grid is about 5 ~ of the rated current of the motor ~ 7 times. After starting the small motor for one or two seconds, the current decreases rapidly as the rotating speed of the rotor gradually rises; while the large motor needs more than ten seconds, even dozens of seconds before the rotor reaches the stable rotating speed. That is, until the start-up ends, the current drops to the rated value. If the starting current of asynchronous motor is high, what problems will it bring to the use? If this motor starts frequently when it is used, the motor will heat severely due to the influence of starting current, which will affect the normal service life of the motor. In addition, if the starting times of the motor used are not frequent, when its capacity exceeds 30% of the power transformer capacity, due to the large starting current, it will cause the overvoltage dr...
