The DC reactor, also known as the flat wave reactor, is mainly used on the DC side of the converter, and has more applications in general inverters. A DC current having an AC component flows through the reactor. The main purpose is to limit the AC component superimposed on the DC current to a specified value, keep the rectified current continuous, reduce the current ripple value, improve the input power factor, and suppress the harmonics generated by the converter.

System Lab and Hunter Whiteness, yellowness measurement, opacity, transparency, light scattering and light absorption coefficients, and instruments for measuring ink absorption.

The biggest difference between a permanent magnet generator and an excited generator is that its excitation magnetic field is generated by a permanent magnet. Permanent magnet is both a magnetic source and a component of a magnetic circuit in a motor. The magnetic properties of permanent magnets are not only related to the manufacturing process of the production plant, but also to the shape and size of the permanent magnets, the capacity of the magnetizer and the method of magnetization. Moreover, the magnetic flux and magnetomotive force that the permanent magnet can provide in the motor also vary with the material properties, size, and motor operating state of the rest of the magnetic circuit. In addition, the magnetic circuit structure of permanent magnet generators is various, the leakage magnetic circuit is very complicated and the leakage magnetic flux accounts for a large proportion, the ferromagnetic material part is relatively easy to saturate, and the magnetic permeability is nonlinear.

Rotary switch is a multi-circuit control electrical appliance which is composed of multiple sets of contact components with the same structure. It consists of operating mechanism, positioning device, contacts, contact system, shaft, handle and other components. The contacts are in an insulated base, which is a double-break point contact bridge structure. The movable contacts are designed to be automatically adjusted to ensure the synchronization during opening and closing. The static contacts are installed in the contact base. It relies on cams and brackets to operate and control the closing and opening of contacts.

A soldering station is a hand tool commonly used in the electronic soldering process. The two workpieces are welded by heating the solder (usually referred to as tin wire) to melt it. The soldering station has a wide range of uses. From common electronic home appliance repairs to electronic integrated circuits and chips, it will be applied to the soldering station as a welding tool, but it is most commonly used for soldering of PCB circuit boards in electronics factories.

ATO single-phase to three-phase converter adopts AC-DC-AC circuit structure and adopts SPWM modulation control technology, which can convert ordinary single-phase power to industrial three-phase power.

A wind turbine converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs AC power equipment. Wind turbines generally consist of blades, generator tails, towers, swivels, and energy storage devices. The blade is used to receive the wind and turn it into electricity through the nose. The tail makes the blade always face the direction of the wind to obtain the maximum wind energy. The rotation can make the nose rotate flexibly to achieve the function of adjusting the direction of the tail. The rotor of the nose is permanent. Magnets, stator windings cutting force lines generate electrical energy.

Industrial camera can be divided into interlaced scanning industrial cameras and progressive scanning industrial camera according to scanning mode.
Most displays and industrial cameras adopt the interlaced scanning, but it actually looks like a smooth image in human eyes. Industrial cameras usually get odd rows of images first, for CCIR standard, industrial cameras get the even rows after 1/50 seconds, but for EIA standard, the industrial cameras get the even rows after 1/60 seconds.

The mig welder has no welding current output.
Fault reason: There is no voltage input at the input end of the welder, the internal wiring is disconnected or broken, the internal coil is burnt out.
Treatment method: Check the switch, wire, fuse and connection part from the distribution box to the input end of the welder. Check that the wiring of the internal switch and coil of the welder is intact. Check if the internal components of the welder are burnt out (it is obvious that the burnt marks are usually burnt, and a special smell will be smelled when burned). If it burns out, it should be replaced.

Welding fume extractor is easy to install, and requires no extra pavement of the smoke pipeline nor professionals' control. The large-power brushless electric machine is equipped to lengthen the service life of the equipment. When the equipment is operating, the noise volume is low, and the air flow is high. The triple filtration design is adopted, including the basic effect filter, intermediate effect filter and primary filter. The multilayer protection has achieved an ideal purification effect, which is above 99%, so the air after purification can be directly discharged indoor. The large-scale basic effect filter can effectively filter out dust of large particles to lengthen the service life of the main filter.

The DC hi-pot tester, though with a higher test voltage, is found with insulation weaknesses, but the insulation of electric appliances is mostly composite dielectrics, whose voltage is distributed by resistance under the effect of DC voltage. Therefore, the DC hi-pot test might not find out the weaknesses of the DC electric appliances under the AC electric field. On the contrary, the AC hi pot tester is in line with the electric conditions imposed on the electric appliance during its operation process. Meanwhile, the AC hi-pot tester is generally higher than the operating voltage. Therefore, after passing the test, the appliance can gain a larger safety margin, so this test has been a major method to guarantee operation safety.

Industrial Vibration motors rely on their own high-frequency vibration to generate the vibration force. Therefore, during the operation process, the motor itself will rise to a high temperature. Because of the existence of the fit clearance, the axle of the vibration motor after the temperature rise will expand. After the expansion, the axle and the bearing should have close cooperation with each other to achieve the normal operating status. Without the fit clearance, the vibration motor after the operating temperature reaches certain level will be faced with a series of problems, which might even stop operation or be burned. Hence, this problem requires more attention in vibration motor maintenance.

The relay contacts’ jumping or switching on/off will cause the change of inductive load and further gas discharge. The current of relay contact on-off is small, there will be no electrical arc between contacts, but there will be a spark at the relay contacts. Due to the existence of inductance in the contact circuit, there will be overvoltage on the inductance when disconnecting the contact circuit. Together with the voltage supply in the contact gap, the contact gap that just separates a little will be broken down and discharged. Limited to energy, there will only be spark discharge. The conversion of capacitance between contacts and energy in inductance makes spark discharge disappear and reappear, becoming a high frequency signal, which will be crosstalk to related circuits by means of high frequency radiation, wire transmission and distributed capacitance, forming interference signals. Furthermore, spark discharges can also damage relay contacts and shorten the service life of contacts, so that sparks may ablate contact surfaces and make the surface uneven, resulting in failure of relay poor contact.

A pneumatic cylinder is a cylindrical metal machine that guides a piston in a straight-line reciprocating movement in a cylinder. The air converts heat energy into mechanical energy through expansion  the engine cylinder, and the gas receives piston compression in the compressor cylinder to increase the pressure.
