The power frequency 220V (380V for 10KVA and above) power supply is connected to the control box (set) (it is the supporting equipment of the test transformer, see the operation manual of the control box (set) for details), and the 0-220v/380v voltage regulated by the autotransformer is input to the primary winding of the YDJ (TDM) test transformer. According to the principle of electromagnetic induction, the power frequency high voltage, which is the same multiple of voltage amplitude, is obtained in the secondary (high voltage) winding according to its ratio to the number of turns of the primary winding. The power frequency high voltage can be obtained by high voltage silicon stack rectification and capacitor filtering, and the amplitude is times of the effective value of the power frequency high voltage. Working principle of oil immersed test transformer

It has a large specific heat and is often used as a coolant. The heat generated during the operation of the dry-type transformer causes the oil near the iron core and winding to expand and rise. Through the up and down convection of the oil, the heat is dissipated through the radiator, and the dry-type transformer operates normally. Dry type transformer oil has the following main functions. Dry type transformer oil has much higher insulation strength than air. The insulating material immersed in oil can not only improve the insulating strength, but also avoid the erosion of moisture.

Special voltage regulators for laser machines, especially for factories with concentrated power consumption or large organizations, must use transformers for accumulation during power consumption, so as to automatically adjust the output voltage, which can better guarantee the safety of power supply equipment of power supply lines. All these advantages of power regulators can be brought into play, In particular, the voltage of the power supply that fluctuates greatly or fails to meet the voltage requirements of the electrical equipment is more stable and can be within a safe fixed value range, so that various circuits and electrical equipment can work normally under the rated voltage and avoid electrical consumption.

Although each module plays an important role in the DC power supply, the rectifier module system does play a fundamental role in the whole system. As the name suggests, it is a module system that converts AC to DC. Because of its special function, it must have good protection function. It can provide barrier free protection in case of overvoltage, overcurrent and over limit output. Fundamental module i.e. rectifier module system

The voltage regulator is an AC voltage regulator, which must consume electric energy, because this voltage regulator is actually a transformer controlled by electronic circuit. The transformer has iron loss and copper loss, and the electronic circuit inside the voltage regulator also consumes electricity. As for the specific power consumption, it should be calculated according to the specific situation. Similarly, a 5000 Watt voltage regulator consumes different electric energy. The main factors are the quality of the product and the size of the load carried by the regulator. However, even if you do not use electricity, the power consumption of the regulator itself is more than 3 watts. Does the AC voltage regulator consume power

When the internal resistance of the power supply can be ignored, it can be considered that the electromotive force of the power supply is approximately equal to the potential difference or voltage between the two poles of the power supply. In order to obtain high DC voltage, DC power supplies are often used in series. At this time, the total electromotive force is the sum of the electromotive forces of each power supply, and the total internal resistance is also the sum of the internal resistance of each power supply. Due to the increase of internal resistance, it can only be used in circuits with low current intensity.
