Selection of large fan inverter in the factory - Reynolds

I often see many beginners tossing on the resistor when overhauling the circuit, and it is dismantling and welding, in fact, it is repaired a lot, as long as you understand the damage characteristics of the resistor, you don't have to bother. Resistors are the most numerous in electrical equipment ...

1. VFD should be operated in an environment above minus 10°C as much as possible, and it is best to operate indoors. 2. When the VFD is started and stopped, try to start and stop with the VFD itself, do not close the power supply, and keep your VFD in a power-on state. 3. Give VFD l ...

A frequency converter is a power electronic device that can change the frequency of an AC power source to control the speed and output power of a motor. Inverters are widely used in industry, aviation, metallurgy, petroleum, chemical industry, electric power and other fields.

1. The switching signal of PLC controls the inverter The PLC can control the start, stop and reset of the inverter through the program; It can also control different combinations of high-speed, medium-speed and low-speed terminals of the inverter to achieve multi-stage speed operation. However, because it is controlled by switching ...

Low-voltage air circuit breaker, also known as active air switch or air switch, belongs to the switch electrical appliance, is used when the circuit is overloaded, short circuit and undervoltage can actively break the circuit of the electrical appliances, can also be used as infrequent start of the motor or opening and closing circuit, low-voltage air circuit breaker has an all-round circuit breaker ...

In power distribution equipment such as voltage distribution cabinets and switchgear at all levels of power plants and substations, the conductors connected between large electrical equipment such as generators and transformers and various electrical equipment are called busbars. Busbars, also known as busbars, are used to collect, distribute, and transmit electrical energy. The connection methods of the bus bar are ...

1. The starting time is different: light load generally refers to the small inertia of the equipment load, and the energy storage balance time of the demand for start-up is short, that is, the starting time is short. Heavy load generally refers to the long time of energy storage balance when the equipment load inertia is large and needs to be turned on, that is, the time of start-up. 2. The requirements for working current are not ...

The inverter is mainly composed of rectifier (AC to DC), filtering, inverter (DC to communication), braking unit, drive unit, detection unit and microprocessor unit. The inverter adjusts the voltage and frequency of the output power supply by the internal IGBT break, and ...

The actuator commonly used in the industrial field of Reynolds inverter has good speed regulation performance and simple and convenient operation method. Therefore, it is widely used in the automation system. Typical wiring method for the main circuit of a Reynolds frequency converter ...

In ancient times, there were ten major tortures, which made people unable to survive and die, and experienced the purgatory of the world; Today, there are ten "tortures" of inverters, and the same can make your inverters suffer. Let's follow the editor to find out which of the top ten "tortures" will make your inverter "worse than dead"! ...

More than 40 sets of RNSVG series low-voltage power generator sets and RNZB series high-voltage reactive power automatic compensation devices designed and produced by Reynolds have been successfully completed and will be delivered in the near future. This product is owned by Shanghai Reynolds ...

The acceleration time of the Reynolds inverter is the time required for the output frequency to rise from 0 to the high frequency, and the deceleration time is the time required to decrease from the high frequency to 0. Generally, the frequency converter uses the frequency setting signal to rise and fall to confirm the acceleration and deceleration time. The rise of the frequency setting must be limited when the motor accelerates.

1. See if it is energy-saving. When selecting equipment products, many business managers will take into account the energy-saving embodiment, which is due to the excellent energy-saving embodiment of the product, which can save a lot of money and resources.

Q1: Why should I use VFD to control the motor? When it comes to this issue, let's take a brief look at these two devices. The motor is an inductive load that hinders the change of current, and when it is started, a large change in current is generated. VFD, which is actually made up of a rectifier inverter circuit, ...

In the process of daily use of soft starters, it is inevitable to encounter some improper use or failure of soft starters in the process of use 1. The user starts ...

1. The wires of the inverter control circuit should be strictly distinguished from the main circuit cable (power line) and placed separately. This effectively prevents the inverter's control circuit from being disturbed by harmonics in the inverter's main circuit. 2. To separate the connection of the inverter from the terminals or contacts of other control circuits, ...

The state proposes to "peak carbon emissions" by 2030 and complete "carbon neutrality" by 2060. Carbon neutrality is to try to reduce carbon dioxide emissions, and eventually achieve net zero emissions, that is, to make carbon dioxide emissions even offset. However, due to economic development, CO2 emissions are stable ...

Each type of servo motor has additional torque, maximum torque and servo motor inertia and other parameters in the standard items, each parameter and load torque and load inertia must have a relevant connection, the output torque of the servo motor should meet the requirements of the movement conditions of the load organization, such as the speed of the acceleration ...

The inverter has power loss during operation and converts it into heat energy, which increases its own temperature. Roughly speaking, the power loss of every 1kVA inverter capacity is about 40W-50W. Therefore, when installing the inverter, it is necessary to consider the heat dissipation of the inverter, and how to run the inverter.

Working environment In the actual application of inverters, most people install inverters directly in industrial sites in order to reduce costs. The job site generally has the problems of large dust, high temperature and high humidity, and in some occupations, there are also metal dust, corrosive gases and so on. There must be ...
