One,Basic Principles

A voltage regulator is an autotransformer with continuously adjustable turns ratio. When the voltage regulator brush slides along the polished surface of the coil with the help of the handwheel spindle and brush holder, the turns ratio can be continuously changed, thereby smoothly adjusting the output voltage from zero toFront high position

3、 Main structure
1，Unit structure:0The. 5KVA and 10KVA regulators are voltage regulating unit structures, with a coil with a polished surface and a wide upper end face
Fixed on the base of the project, the electric brushes of the contact group are in close contact with the polished surface of the coil under spring pressure. Turning the handwheel drives the electric brushes to slide on the polished surface of the coil for voltage regulation. The unit voltage regulator is generally a desktop with a protective ventilation cover on the outside
2，Single phase assembly structure: A single-phase large capacity voltage regulator is assembled from several units of the same specifications, with the brush contacts of each unit assembled on the same spindle. The coil input end is connected in parallel, and the output end is connected to a balancing reactor to balance the current distribution between units and suppress circulating current.
3. Above 10KVAfromTwo or three or moreUnits of the same specifications are assembled coaxially.
4，Electric brush structure: Unit voltage regulators of 3KVA and below use 1-2 graphite electric brushes and metal frames with good heat dissipation. Unit voltage regulators of 4KVA and above use two copper graphite composite electric brushes. The pressure plate of the electric brush contact group is fixed to the upper end of the coil to limit its axial position, and is locked to the main shaft by screws. When dismantling, replacing the main shaft, or extending the main shaft from the bottom of the voltage regulator, simply loosen the screws to facilitate the process.

4、 Scope of adaptationTDGC2、TDGC2J、 The series voltage regulator has the characteristics of waveform distortion free, small size, light weight, high efficiency, easy use, reliable performance, and long-term operation, achieving the purpose of voltage regulation, temperature control, dimming, power control, etc，Widely used in chemical, metallurgical instruments, electromechanical manufacturing, light industry, scientific experiments, public facilities, household appliances, temperature and speed control, dimming, and power control, etcofIt is an ideal AC voltage regulating power supply.

1. Environmental temperature: high temperature+40 ℃, low temperature-15

2. Altitude: The installation location of the regulator should not exceed an altitude of 1000 meters

3. Relative humidity of the air: The average relative humidity in a humid month is 90%, and the average temperature in that month is 25 ℃

4. Power supply voltage waveform: The power supply voltage waveform is a sine wave or approximately a sine wave

5. The installation site is free from gases, vapors, chemical deposits, dust, dirt, and other explosive and corrosive media that seriously affect the insulation of the regulator;
6. The installation site should be free from severe vibrations and bumps;

7. Indoor use;

Attention! -Selection prompt: This regulator product cannot be used in parallel with multiple units

5、 Pre use testing and maintenance

1，Newly installed or long-term unused voltage regulators must measure the insulation resistance of the coil to ground with a 500 volt megohmmeter before operation. Only when the value is not less than 5 megohms can it be used safely. Otherwise, it should be subjected to heat drying treatment. The heat drying treatment method can generally be electric drying or sent to a drying room for drying. After drying, check whether the fasteners are loose, and if they are loose, tighten them

2，The power supply voltage should comply with the input voltage on the regulator nameplate.

3，The regulator must be well grounded to ensure safety

4，When using, it is important to regularly ensure that the output current does not exceed the rated value. If there is a short-term load, it should not exceed the specifications in Table 2, otherwise it may reduce the life of the regulator or even burn it out

5，When using, the handle should be rotated slowly and evenly to avoid damaging the electric brush or generating sparks

6，The use of the voltage regulator should be checked regularly. If excessive wear or defects are found in the brushes, they should be replaced with brushes of the same specification in a timely manner. Zero grit sandpaper should be used to pad the brushes under them, and the handwheel should be rotated several times to make the bottom surface of the brushes smooth and in good contact before use. The replaced copper graphite composite electric brush must strictly meet the specification requirements.

7，The surface between the coil and the brush should be kept clean regularly, otherwise it may cause sparks and burn out the coil surface. If black spots are found on the surface of the coil, they can be wiped with cotton yarn dipped in alcohol (90%) until the surface spots are removedstop

8，The wires and wire terminal joints from the power supply to the regulator and from the regulator to the load should have good contact and be able to pass the rated current of the regulator.

9，When moving the regulator, do not use a handwheel, but instead use a handle or lift the entire product for movement

10，The regulator needs to be horizontally installed on the panel, （limitWhen installed on a unit regulator structure or other bases, the mounting holes on the regulator base can be used to secure it.

11，The regulator should be kept clean regularly and no water droplets, oil stains, etc. are allowed to fall into the regulator. The regulator should be powered off regularly to remove accumulated dust inside.
