Product Description
Control transformer is an electrical transformer that is used to provide power and control signals to electrical circuits, and can also be used to monitor and control electrical parameters, such as voltage, current, and frequency. It typically consists of a primary coil and a secondary coil, with a third winding called a common coil. The primary and common coils are connected in parallel to the load, while the secondary coil is connected in series with the load.
Qinghao Control transformers are commonly used in industrial control systems, where they provide power and control signals to a variety of devices, such as motors, pumps, and controllers. They can also be used to isolate electrical systems, reducing the risk of ground loops and other problems that can arise when different circuits are connected together. The output is proportional to the voltage applied to the primary coil, while the output current is proportional to the voltage applied to the common coil. This allows our control transformer to provide precise and accurate control signals to the load.
Main Characteristics:
1. Voltage Rating: It is the maximum voltage the transformer can safely handle without damaging itself or the connected equipment.
2. Power Rating: The power rating of a control transformer is the maximum power it can handle without overheating or failing. It is typically measured in kilowatts (kW) or horsepower (HP) and is related to the voltage rating and size of the transformer.
3. Protection and Isolation: Control transformers are designed to protect connected equipment from damage due to voltage or current spikes, overloading, and short circuits. They also provide isolation between the control system and the connected equipment to prevent ground loops and electrical hazards.
4. Connector Configuration: Control transformers have different connector configurations depending on the type of equipment they are connected to. Common connector configurations include slip rings, contactors, and remote controls.
Advantages:
1. Accurate: Have a low harmonic content and minimal voltage and current spikes that improves the accuracy of control signals, resulting in better performance and efficiency.
2. Improved power quality: Control transformers help to improve power quality by reducing voltage sags and spikes, improving the stability of the system, and reducing the effects of voltage drops.
3. Low noise and interference: Low levels of noise and interference make them ideal for use in high-voltage power systems.
4. Fireproof, explosion-proof, pollution-free and able to be directly installed in the load center.
5. Easy installation, operation and maintenance.
Applications
Mainly used for electric motor control systems, power protection systems, measurement and monitoring systems, instrumentation systems, robotics and automation systems.
