Why need the Explosion-proof frequency converter or VFD inverter?
Explosion-proof frequency converter is the application of frequency conversion technology and microelectronics technology to control the power transmission components of AC motors by changing the frequency and amplitude of the motor's working power supply. Because the coal industry has a higher risk factor, there are a lot of flammable and explosive gases, dust and other dangerous gases underground. A small mistake during operation can lead to a massive explosion. In order to ensure the smooth progress of underground operations and be responsible to coal miners, the equipment used in the coal industry must be non-dangerous, and explosion-proof is the primary condition. The explosion-proof inverter has its own voltage detection function during the output process, and at the same time automatically adjusts the output voltage to protect the machine motor. When the motor voltage is lower than 90% of the normal voltage, the explosion-proof frequency converter will automatically stop to protect the motor. The explosion-proof inverter can not only protect the motor through voltage protection, but also through current protection. When the motor current exceeds 150/3 seconds of the rated value, the explosion-proof frequency converter will stop to protect the motor. When the load on the drive system suddenly becomes lighter during operation, it means that an accident has occurred in the work of the production machinery. At this time, the explosion-proof frequency converter will stop working immediately to prevent accidents. The frequency converter is equipped with a dedicated grounding protection wire. If an accident occurs, the frequency converter will immediately call the police. When the output of the inverter is short-circuited, it will inevitably lead to over-current. At this time, the explosion-proof frequency converter will be shut down in a short time to protect the motor. We cannot avoid dangerous work, but at least we can reduce its risk factor as much as possible. Therefore, the explosion-proof frequency converter still has a great effect.
