Reynolds universal inverter start-up mode

We need to ensure that the capacity of the inverter is matched. First of all, according to the nature of the load, the correct selection of the type of inverter. When selecting the inverter, the current value of the actual motor should be used as the basis for the selection of the inverter, and the rated power of the motor can only be used as a ...

Bypass cabinet: The cabinet is equipped with high-voltage inlet and outlet isolation switches QS1 and QS2. Among them, QS1 is a single-pole single-throw variable frequency incoming knife switch, and QS2 is a single-pole double-throw power frequency and variable frequency outgoing knife switch. The bypass cabinet is a high-voltage environment, please investigate the status of the live display and electromagnetic lock to ensure safety before ...

RNVH-A series high-voltage inverter adopts multi-unit series multi-level technology, which is attributed to high-high voltage source inverter, which can directly input 6KV/10KV and direct 6KV/10KV output. Taking the 6KV series as an example, each phase is connected in series by 5 power units, and each power unit is isolated by the input transformer.

Reynolds soft starters include soft starters for high, medium and low voltage motors, including JJR1000 series, JJR2000 series, JJR5000 series, and RNB3000 series frequency converters. Reducing the starting power supply avoids voltage drops and voltage dips in the power supply. Smooth start-up avoids product damage. ...

1. Pole change logarithmic speed regulation method This speed regulation method is to change the number of stator poles of the cage motor by changing the connection method of the stator winding, so as to reach the intention of speed regulation; The wiring is simple, the control is convenient, and the price is low; It can be used in conjunction with pressure and speed regulation, electromagnetic slip clutch to obtain high efficiency ...

Misunderstanding: connect electromagnetic switches and electromagnetic contactors in the output circuit of the inverter In actual use, some occasions require the use of contactors for frequency converter switching: such as when the frequency conversion is faulty, switch to the power frequency operation, or when the one-to-two method is adopted, a motor is faulty, and the variable frequency is used.

Capacitor series reactors generally adopt epoxy glass fiber multi-encapsulated parallel structure, according to the characteristics of the device site, three-phase vertical stacking, three-phase horizontal "△" and three-phase horizontal "-" type distribution. The substation in the southern area ...

1. Problems of the inverter and the motor itself; After the motor has been used for a long time, it cannot be ruled out that the insulation function is not good, or the bearing is stuck, and it may show a large current and heat. The coupling between the motor and the load may also be worn, or the motor is unbalanced in three phases, and the fixtures of the motor are loose.

The inverter is an electric control equipment that uses frequency conversion technology and microelectronic technology to control and communicate the motor by changing the power supply frequency of the motor operation. The inverter is mainly composed of rectifier (AC to DC), filtering, inverter (DC to communication), braking unit, drive unit, detection unit ...

There are two types of inverter parking. One form is called "free parking". As the name suggests, it is to quickly "power off" the motor, so that the motor can slide and park by its own inertial force (OFF2 parking); The other form is called "brake parking". So this "brake parking ...

How to use a multimeter to measure the quality of the inverter, it needs to be noted that for personal safety, it is necessary to ensure that the machine is powered off, and remove the inverter input power line R, S, T and output line U, V, W before operation! First of all, the multimeter is hit to the "secondary pipe" file, and then through the multimeter ...

Variable frequency speed regulation can be used in most motor drag occasions, because it can provide accurate speed control, so it can easily control the rise, descent and variable speed operation of mechanical transmission. The use of frequency conversion can greatly improve the efficiency of the process (the variable speed does not depend on the mechanical part) and at the same time ...

Reynolds inverter brochure (partial) 　　Before installing When unpacking, it is found that the machine has water or left water traces, indicating that the inverter has been flooded, so please do not install and use it. When unpacking, it is found that the machine is damaged and deformed or the parts are missing, please do not install and use it, otherwise there will be fault expansion and personnel ...

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 ...

The high-voltage inverter has been designed with the safety of the user in mind. However, due to the energy storage capacitor installed inside the power unit of the inverter, it may still carry a high voltage after disconnecting the power supply, and some parts generate a lot of heat, so contact is prohibited. When working on or near the inverter, please ...

There are many kinds of components of the inverter, different components have different functions, and different components have different specializations! In addition to the composition and application of Aideley inverter, there are also key components of inverter to provide for the operation of inverter.

1. The constant pressure water supply of the inverter increases the comfort of water supply by 3 times 2. Constant water pressure, reducing pipe bursts and leakage by 80% 3. High efficiency and energy saving, power saving effect up to 20%-60% (depending on the actual situation) 4. The use of frequency converters can realize multi-point pressure in different time periods.
