What is the difference between a contact regulator and a transformer

1. The working principle is different: the input range of the voltage regulator slides arbitrarily from 0V to the rated value range, and the point of the input voltage can be adjusted at any time to meet the stability of the output voltage. Whereas, transformers use the principle of electromagnetic induction to change alternating current.

The voltage device realizes the conversion of voltage according to a certain conversion ratio.

2. Different properties: transformer is an electrical equipment used for electric energy conversion, which can convert one voltage and current alternating current into another voltage and current alternating current of the same frequency. To put it simply, it is to convert different alternating current energy into alternating current energy of the same frequency.

3. The control motor is different: the working principle of the voltage regulator is the same as that of the transformer, the only difference is that it has a control motor, which can adjust the output voltage by changing the ratio of the coil tie.

For example, the transformer is 380V to 12V 36VThis specifies the variable number. It can only be changed to 36v 12v

But the voltage regulator is 380V, and then the output is adjustable in the range of 0, 500, 0, 300, etc., and so on.

Got it.

Contact regulators are output voltage adjustable. It is mainly used in the testing industry.

The transformer is a coil fixed tap type, and the voltage is a fixed value. It is mainly used for power supply.

The working principle of the voltage regulator is that of an autotransformer, which changes the voltage by rotating the handwheel to change the ratio of turns of the secondary side contact to the contact position of the coil.

The transformer works by directly changing the coil.

The number of turns on the primary and secondary sides changes the voltage.

Both are transformers. The difference is that the output voltage of a general transformer is fixed. The regulator has a sliding contact and a toroidal coil.

It is possible to change the position of the contacts on the toroid. Thus different voltages are output. The other is to use electronic components or relays to adjust the voltage by changing the different taps of the secondary line group.

The difference between a transformer and a voltage regulatorTransformers are often used in electrical equipment and wireless circuits to rise and fall voltage, match impedance, and safety isolation.

When the input voltage or load changes, the control circuit sampling, compares, amplifies and then drives the servo motor to rotate, so that the position of the carbon brush of the transformer changes, and the ratio of turns of the coil is automatically adjusted, so as to maintain the stability of the output voltage. The voltage regulator with a large capacity also works on the principle of voltage compensation.

The range of transformers is very large, it is a big concept, and voltage regulators belong to a branch of transformers.

There is a difference, the transformer primary stage is generally two separate windings, the common voltage regulator, also known as autotransformer, has only one winding, using taps to adjust.

The transformer belongs to the transmission and distribution line, and the voltage regulator belongs to the test equipment.

Transformers are often used in electrical equipment and wireless circuits to rise and fall voltage, match impedance, and safety isolation.

When the input voltage or load changes, the control circuit sampling, compares, amplifies and then drives the servo motor to rotate, so that the position of the carbon brush of the transformer changes, and the ratio of turns of the coil is automatically adjusted, so as to maintain the stability of the output voltage. The voltage regulator with a large capacity also works on the principle of voltage compensation.

The voltage regulator is a self-coupling transformer with continuously adjustable turn 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 turn ratio can be continuously changed, so that the output voltage can be smoothly adjusted from zero to the maximum value.

The small power is stepless smooth adjustment, that is, a toroidal autotransformer, the surface of the winding is polished to remove the patent leather, and the physical position is adjusted with graphite (carbon fine) brushes, which adjusts the effective number of secondary winding turns, which can be bucked or appropriately boosted.

The high-power is step-level regulation, divided into load and no-load regulation, that is, whether the output voltage can be adjusted with load. The principle of voltage regulation is to change the number of turns of the secondary coil of the autotransformer to achieve the purpose of changing the output voltage, and the three-phase 380 voltage is adjusted to the voltage level you need through the voltage regulator.

The voltage regulator is a device that can adjust the output voltage, which can be adjusted both high and low, and is divided into five types: oil-immersed voltage regulator, auto-coupling voltage regulator, isolation voltage regulator, induction voltage regulator, column electric voltage regulator and thyristor voltage regulator, and the voltage regulator of automatic voltage regulation can achieve voltage stabilization.

A voltage regulator is a fixed voltage input with a range of voltage outputs, while a voltage regulator is the opposite.

The contact regulator has an auto-coupling coil structure inside, which can be reversed for voltage regulation, but there are a few things to be aware of:

1. Contact voltage regulator and contact voltage regulator are both current constant design, when the voltage is low, the capacity will be insufficient, to be clear about the maximum current of input and output, can not exceed the rated value on the nameplate of the voltage regulator, otherwise it is overload, serious will burn out.

2. There are two kinds of contact voltage regulators: manual voltage regulation and electric voltage regulation, while the voltage regulator is an automatic voltage regulation, and the voltage regulation process is carried out through a set of voltage sampling and adjustment devices. For the contact regulator of the electric pressure regulation mode, such a matching device can be directly installed, and the manual mode needs to be changed to electric first.

3. As for the speed of adjustment, it is related to the motor on the original voltage regulator, and the speed is the same; The service life is related to the voltage regulation accuracy and the frequency of voltage fluctuations. The higher the voltage regulation accuracy or the more frequent the voltage fluctuation, the more frequent the voltage regulation action will be, and the life will be relatively shorter.
