The motor frequency conversion speed control box can change its output frequency To adjust the speed of ordinary three-phase asynchronous motors to meet the requirements of the production process or to achieve power saving purposes, the power saving rate can reach ~, it can also be used as a motor soft start controller, or can be controlled through sensors, transmitters, etc. The circuit forms a closed-loop speed regulation system. The installation operation is simple, the starting balance has no inrush current (the capacity of the soft starting power supply is greatly reduced, the power factor is constant, and it also has various functions such as applause display.
Since the core device of the speed control inverter is a single-chip microcomputer, it has many functions. Strong functions
Over-current protection, short-circuit protection, over-voltage protection, under-voltage protection, instantaneous power failure protection and end-phase protection.
Digital display or indicator or pointer can display frequency, speed, load rate or current Etc.
The frequency can be adjusted manually. The process curve in which the rotational speed changes according to time can be set. The frequency can also be controlled by giving a signal from the system.
Steel pipe or cable wiring.
Meet the standard requirements.
The speed regulating frequency of this product is imported components. The cabinet is also equipped with ammeter, voltmeter, automatic air switch, indicator light, AC contactor, power frequency conversion switch and start and stop buttons. It can be adjusted according to different needs. The process requires the design, selection of components and preparation of various appropriate operating methods.
Meaning of applicable scope groups
Division of explosive gas environment hazardous areas
Different countries and regions, according to their respective Standard division of explosion hazard areas. Our country divides explosive gas environments into zones, zones and zones based on the frequency and duration of the occurrence of explosive gas mixtures. (Consistent with the International Electrotechnical Commission)
Zones where explosive gases appear continuously or for a long time The environment of the mixture.
The area may have an environment in which explosive gas mixtures may appear during normal operation.
The area may not have an environment in which explosive gas mixtures may appear during normal operation, or even if it does, it will only exist for a short period of time. The environment of the mixture.
The zone generally only exists in the internal gas space of sealed containers, storage tanks, etc. In the actual design process, the zone rarely exists, and most cases belong to the zone.
Explosive electrical equipment is divided into Category II
Category I electrical equipment for underground coal mines
Category II electrical equipment used in places other than mines
Category electrical equipment is suitable for the maximum test safety clearance or minimum ignition of explosive gas mixtures. The current ratio is divided into three categories: II, II and II, and divided into six groups according to their maximum surface temperature.
Explosive gas mixtures are grouped according to ignition temperature, see table.
Explosive gas mixtures, according to The maximum test safety gap or minimum ignition current ratio classification is shown in the table.

Properties: Under specified test conditions, the ratio of the minimum ignition current of explosive mixtures of gases and vapors to the minimum ignition current of explosive mixtures of methane. China regulates the hazards of gases and vapors Substances are classified into Class II [forbidden words], Class II and Class II according to the minimum ignition current ratio. The minimum ignition current ratio is Level II [forbidden word], and the minimum ignition current ratio is Level II. For example, ethane, ethylene, and acetylene are Class II [banned words], Class II, and Class II hazardous substances respectively.
