Traditional phase conversion system adopts rotary transformation technology, which has 50 years of history and simple product structure in early times. It consists of a transformer, three-phase motor, capacitor and relay control circuit. As long as the 220V power is connected, the auxiliary motor starts, the starting capacitor is disconnected and the motor is turned into a generator, thus producing missing phase. A fairly rough three-phase electric lead can be produced to provide power supply for other electrical equipment. Such a traditional conversion system doesn't have the adaptive control function, so there are many defects in its application. When the load varies widely, the three-phase output voltage will be unbalanced. At free load or light load conditions, the output voltage will rise to more than 25% of the rated output voltage; When the load is too large, it will also greatly reduce the output voltage, making it difficult for the device to start or stop running. However, the single phase to 3 phase power converter of ATO uses many important new technologies, the newly invented built-in micro-control computer control program makes our products to have a qualitative leap in conversion efficiency and performance.

Current transformer is mainly used to measure the current of busbar and primary side with iron core coils in AC occasion. It can detect the DC current, can be single core or dual cores, generally, it's equipped with auxiliary DC winding. Such a structure is simple, reliable and slow. Technology and design of the current transformer are complex, its common precision is 5%, it's difficult to reach 0.5% because phase position and compensation are difficult. A current transformer is an electrical component that turns large current into small current, it doesn't change the current frequency but only the size. Its secondary side current is 5A, that means the output rated current is 5A. It's mainly used for electrical control, measurement, protection and signal.

Through the relative motion of the rotating magnetic field generated by the stator (its speed is synchronous speed n1) and the rotor winding, the rotor winding cuts the magnetic induction line to generate induction electromotive force, thus induced current is generated in rotor winding. The induction current in the rotor winding acts on the magnetic field to produce electromagnetic torque, thus making the rotor rotate. As the rotor speed approaches the synchronous speed, the induced current decreases and the electromagnetic torque decreases accordingly. When the asynchronous motor works in the motor state, the rotor speed is smaller than the synchronous speed. In order to describe the difference between rotor speed n and synchronous speed n1, slip ratio is introduced.

In modern industrial equipment, particularly when using in the high precision conditions, the servo motor technology is developed into high torque density, as a result, the rotation speed may be up to more than 3000 rpm. With the improvement of rotation speed, power density of servo motor is also greatly improved, that means whether a servo motor needs to be matched with a reducer gearbox is mainly determined by the application need and the cost. In following application conditions, a servo planetary reducer gearbox is needed.

The input reactor is used to restrain the sudden changes in the grid voltage and the current impact caused by overvoltage, smooth the peak voltage contained in the power supply voltage or the voltage defects caused by commutation of bridge rectifier circuit, thus effectively protecting VFD and improving power factor. It can not only prevent the interference from the power grid, but also reduce the pollution of the harmonic current generated by the rectifier unit to the power grid.

The oscilloscope probe is mainly used to guide the measured voltage signal from the measuring point into the oscilloscope for measurement. Probe is crucial to the accuracy and correctness of the measurement results, as it's the electronic component connecting the measured circuit and the input of the oscilloscope. The simplest probe is a wire that connects the measured circuit and the input of the oscilloscope, a complex probe consists of resistor-capacitor unit and active devices. A simple probe has no shielding measures, so it's susceptible to external electromagnetic interference. Meanwhile, larger equivalent capacitance in it would increase the load on the measured circuit, thus leading to distortion of the measured signal.

The gas solenoid valve is used for various ambient temperature, high temperature, negative pressure, low pressure and high pressure applications. The applicable fluid is air, nitrogen, oxygen, hydrogen, helium, carbon dioxide gas, argon gas, methane and other gas pipelines. Generally, solenoid valve for gas is mainly used in wide applications such as medical apparatus and instruments, rubber plastic machinery, clothing equipment, drying equipment and pharmacy industry, cooling industry, HVAC industry, electroplating coating industry, food and beverage industry and vacuum equipment industry.

ATO miniature circuit breaker is mainly used for AC 50Hz or 60Hz, voltage ratings 230/400V, 240/415V and 277/480V, and current ratings from 1A to 63A. The miniature circuit breaker is characterized with compact structure, reliable performance, strong breaking capacity and beautiful appearance. It can be applied for overloading and short-circuit protection of lighting, distribution lines and equipment of office buildings, houses and similar buildings.

For some Microcontrollers, the resistance of sensor connected must be less than 10kΩ when carrying out the A/D transformation. For example, the resistance of Analog Devices's analog acceleration sensor is 32kΩ. It can’t work normally on the PIC and AVR control board. So it’s suggested to read the controller manual carefully before purchasing the sensor, so as to ensure that the sensor can work normally.

Frequent starting leads to excessively high temperature, overheating protection of the soft starter thereof operates (starting frequency of the soft starter shall be controlled within 6 times per hour, particularly in heavy load). Protective elements act at starting, which makes the contactor unable to by pass, the soft starter works for long time and thus causing the protection to act (check peripheral circuit). Heavy load and long starting time lead to overheating protection (reduce load as far as possible when starting). Parameters of soft starter are improperly set. Long starting time and low starting voltage (increase the starting voltage). Radiator fan of the soft starter can't work normally (replace a fan).

The load cell has a certain overload capacity, but it shall still be prevented from overloading in installation. It should be notified that even a short-term overload can still cause permanent damage to the sensor. During the installation, a pad with the same height of the sensor could be firstly used instead if necessary, then replace the pad with the sensor. In normal operation, the sensor should generally be equipped with mechanical structure for overload protection. If the sensor is fixed with screws, the screw should have a certain fastening torque and screwing thread depth. Generally, high strength screws should be used.

ATO Single phase to 3 phase converter has the function of filtering the grid disturbance and interference at the same time, which is a good performance of stabilized voltage and frequency power, to provide a more stable and pure power supply environment for the back end devices. Intelligent fan speed control system, low no-load loss. LCD display, high efficiency, easy installation. The output frequency 50Hz/60Hz can be set.

As everyone knows, direct starting of water pump would cause the water hammer effect. Namely when the water pump starts and stops, water impacts the pipe and cause a serious water hammer. When the power is off suddenly or the valve turns off quickly, a water impact wave generates due to inertia of pressure flow, which is like the knock of a hammer, so it’s called water hammer. Sometimes the force generated from water impact wave may be great and damage valve or pump, therefore, to avoid the negative effect of water hammer effect, the pump’s rotation speed should increase to the rated speed slowly when it’s started. Two methods are applicable, one is the variable frequency starting, another is the soft starting.

When selecting a output line reactor, its function shall be firstly determined, then the reactance ratio can be selected according to its functions, finally, the output line reactor capacity is selected according to the capacitor capacity (reactor capacity is equal to the capacitor capacity multiplied by reactance ratio). Selection of a reactor is complex, power grid quality and parameters, capacitor parameters shall be determined.
