What is a control transformer?
The control transformer is a power transformer used in an electrical control system, whose main function is to provide the control power required for the control loop. The control transformer works through the principle of electromagnetic induction to convert high voltage into low voltage to meet the voltage requirements of different electrical components. It is usually used in machine tools, mechanical equipment as an electrical control lighting and indicator power supply. It is suitable for AC 50Hz or 60Hz, voltage 1000V and below the circuit and can work continuously under rated load for a long time.
What is a power transformer?
The power transformer is a device that converts bulk electrical power from one frequency to another. It uses an electromagnetic field to create a magnetic field in the metal coils, which stores electrical energy and then provides it back in the form of an electric field when the action button is turned on.
What is the difference between a control transformer and a power transformer?
The control transformer is mainly used to provide power for the control system and ensure the normal operation of the equipment. It is usually used in AC 50Hz or 60Hz circuit. The voltage is 1000V and below. It is suitable for machine tools, mechanical equipment as electrical control, lighting and indicator power supply. The control transformer has a variety of output voltages to meet the needs of different electrical components, and can work continuously for a long time under rated load .
Power transformers are mainly used for voltage transformation in power systems to achieve the transmission and distribution of electrical energy. It is characterized by large capacity, high voltage level, and usually adopts oil-immersed or dry structure. Power transformers use insulating oil or use solid insulating materials as a cooling and insulating medium. Power transformers are mainly used to transfer electric energy between different voltage levels of the power grid. For example, the transformer in the regional substation is used to exchange electric energy between two power grids. The capacity of this transformer is very large and this transformer does not serve as the task of supplying power to users .
Structurally, a control transformer consists of a primary winding and one or more secondary windings that can be rotated or slid to regulate the output voltage. A power transformer usually consists of two mutually insulated windings. The input and output ends are isolated to ensure complete electrical insulation .
In terms of application, control transformers are mostly used in machine tools and mechanical equipment as electrical control, lighting and indicator power supply, and are also often used as control system power supply in low-voltage distribution systems. Power transformers are widely used in regional substation voltage transformation as well as the transmission and distribution of large capacity electric energy .
Here are some differences between control transformers and power transformers that are summarized:
·Control transformers are more widely used than power transformers.
- Control transformers are more expensive than power transformers.
·Control transformers are larger than power transformers.
·Power transformers usually need to be customized while control transformers have many standard specifications.
