cable detects the high-voltage power supply-manufacture,factory,supplier from China

How to use high voltage power supply to detect high voltage cablesTo ensure the normal and safe use of high-voltage cables, check the cable inlet before or after using them for a period of time. The test includes determining whether the main insulation is damp or aging, and checking whether there are defects in the main insulation of the cable after the voltage test. High voltage power supply is the main tool used for voltage resistance and insulation detection of cable.The source of Radium specially produced a power supply type for the high voltage test of power supply :HY-12KV and HY-32KV.

Along with the continuous development of economy in our country, most areas begin to produce electric power equipment, which makes the national grid electric power output insufficient, coupled with the aging of the power output facilities, eventually causes the voltage at the end of the circuit to be too low, which brings great influence on the stability of laser output. The stable output of laser energy is a necessary condition for laser production.

Source of electrical noiseNoise is generated when there is a rapid jump in the voltage or current waveform. In a switching power supply, many waveforms are periodic, that is, pulses containing high frequency edges repeat at a predictable pulse repetition rate (PRF). For a rectangular pulse train, the reciprocal of the period determines the fundamental frequency of the waveform. The Fourier transform of a rectangular wave contains a large number of harmonics at the fundamental frequency.

Laser power supply technicians are important members of the operation of laser equipment, but in the operation of laser power supply, will also encounter all kinds of difficulties, today we summarized some of the first-line manufacturers of technical personnel to provide common problems to discuss with you:▲ Power failure:Problems occur: Because the laser power supply system, especially the high-power laser power supply system requires a large amount of voltage, if the voltage is not stable, it will produce inconsistent output power, resulting in catastrophic damage.Solution: If you do not hav

Laser power supply technician is an important member of the operation of equipment, but in the operation of laser power supply, will also encounter a variety of difficult problems, today our factory technicians summed up the following problems, and according to the problem one by one to solve the problem, these problems are very key, I hope to pay attention to.▲ Power failure: Because the laser power supply system, especially the high-power laser power supply system needs a lot of voltage, the power supply related problems will produce inconsistent output power, leading to catastrophic damage.

Ultrasonic generator common failure and maintenance methodsUltrasonic generator is a kind of equipment that converts the mains power into the corresponding high-frequency alternating current of the transducer to drive the transducer to work. It is an important component of the high-power ultrasonic system. It can also be called electronic box, ultrasonic driving power supply and ultrasonic controller. Although the ultrasonic generator can also be called the ultrasonic drive power, but in fact, the ultrasonic generator is only a part of the ultrasonic drive power.

　　Portable laser marking machine is a device that uses laser technology to marking, which is usually used to engrave text, patterns, logo on the surface of various objects. It has the feature of simple operation, flexible operation, good engraving effect, and is widely used in jewelry processing, crafts, mold processing, woodworking, leather processing, paper-cut engraving and other fields. So what is the conventional voltage of the portable laser etching machine?

Selection and use of semiconductor laser power supplyFirst, the basic requirements of semiconductor laser power supply1. Constant current output: short-circuit constant current output, load changes or short-circuit automatic adaptation.2. Output current ripple: ripple, noise and rated output current cannot exceed the maximum current that the laser tube can bear.3. Output voltage ripple: Ripple voltage noise will not damage the laser immediately, but if serious, it will affect the life of the laser.4. Soft start: Slow start current curve, no overshoot.5.

The basic principle of PWM switching power supplyAlthough pulse-width-modulated (PWM) switching power supplies have been around for a long time, they were not widely accepted and used until the mid-1970s. Switching power supplies have many advantages over linear power supplies.For the same power capacity, switching power supplies are more efficient and smaller than linear power supplies, but the design is more complex and electromagnetic interference (EMI) is more severe.There are two approaches to the current design of switching power supplies.

The control part of pulsed laser power supply mainly consists of signal source, signal processing and delay regulation, pulse power amplification, energy storage voltage control and other circuits. The main circuit structure of the pulsed laser power supply we developed adopts resonant switching technology, which can be closed when the current passes zero, effectively reducing the switching loss and improving the conversion efficiency.
