[0040] The power transformer 6 is a JB / T3837 power transformer with stable power compensation.

[0041] The power transformer 6 described in this patent is a stationary electrical device used to convert a given AC voltage (current) into one or more different voltages (currents) of the same frequency. When AC current is applied to the primary winding, an alternating magnetic flux is generated. This alternating magnetic flux, through the magnetic conduction of the iron core, induces an AC electromotive force in the secondary winding. The magnitude of the secondary induced electromotive force is related to the number of turns in the primary and secondary windings; that is, the voltage is proportional to the number of turns. Its primary function is to transmit electrical energy, so its rated capacity is its primary parameter. Rated capacity is a commonly used value that represents the amount of power transmitted, expressed in kVA or MVA. When the rated voltage is applied to the transformer, it determines the rated current that does not exceed the temperature rise limit under specified conditions. Amorphous alloy core distribution transformers are particularly energy-efficient. Their greatest advantage is their extremely low no-load losses. Ultimately, ensuring these no-load losses is a key consideration throughout the design process. When arranging the product structure, in addition to considering that the amorphous alloy core itself is not affected by external forces, the characteristic parameters of the amorphous alloy must also be accurately and reasonably selected during calculations.

[0042] Working principle: First, install the power quality management device to the appropriate position, connect the power cord 11 to the external power supply to provide sufficient kinetic energy for the operation of the equipment. When it is necessary to perform power detection on the external connection line, set the line collection device 7 on the left side of the power transformer 6, and fix the line collection box 71 to the power transformer 6 through the fixed plate 73. Pull the handle 75 outward to open the line collection box 71, and pull the first fixing buckle 764 and the second fixing buckle 765 to the right to facilitate the external power connection line to be inserted into the line collection box 71 through the line hole 72 in turn and connected to the line collection slot 763 in the plate body 761. The plate body 761 is fitted with the inner side of the line collection box 71 through the adhesive pad 762, and the line collection slot 763 is aligned with the line hole 72. The connecting line is connected to the power transformer 6 in turn through the slot 766 in the line collection slot 763. The device 6 is connected, and then the first fixing buckle 764 and the second fixing buckle 765 are pulled to the left to clamp the connecting wires in the collection trough, and the switch door 74 is closed to achieve the beneficial effect of orderly storage of the connecting wires in the power quality management device, which is convenient for workers to identify, prevents excess wire ends from tripping passers-by, and improves the management efficiency. Then, the power quality detector 1 is started by pressing the controller 5 to detect the power quality of the external connecting wire. The detection data is processed by the microprocessor 9 and displayed on the display screen 4. When it is detected that the voltage in the connecting wire is too low, the power transformer 6 is started by the controller 5 to compensate for the voltage in the connecting wire so that the voltage in the connecting wire is consistent. Finally, when the equipment stops running, the knob 3 is turned to open the flip cover 2 to facilitate maintenance and care of the inside of the power quality detector 1.
