Introduction
The core of a toroidal transformer is a transformer that is seamlessly rolled with high-quality cold-rolled silicon steel sheets. The coil of the toroidal transformer is evenly wound on the core, and the direction of the magnetic field lines generated by the coil coincides almost exactly with the core magnetic circuit, and the excitation energy and core loss will be reduced by 25% compared to the laminated type.Diagram customization.
Application
Toroidal transformer is a type of transformer used in power systems, which is widely used in protection, measurement and other aspects of power systems. Common application areas include:
1. Current transformers: Toroidal transformers act as current transformers to measure and protect the current in the system.
2. Voltage transformer: Toroidal transformers are used as voltage transformers to measure the voltage in the system.
3. Power quality monitoring: Toroidal transformers can be used to monitor power quality in the power system, such as voltage, current, power factor, etc.
4. Smart grid: The imaging function of toroidal transformer can be used for fault detection, online monitoring, etc. in smart grid.
Product features
The main advantages of toroidal transformers are lower radiation field and higher efficiency.In the case of halving the size and weight, a given capacity can be reached, if a transformer with a slightly larger capacity is used, the temperature of the transformer can be reduced.The center hole fixing method makes the toroidal transformer easy to install on the printed circuit board.Toroidal transformer has a high degree of flexibility, and the size of the transformer can be designed according to the requirements of the chassis and the overall assembly. Since the production of toroidal transformers does not require a die, nor does it require a coil skeleton injection mold, the production cycle is short, suitable for small and medium-sized batch production, and can meet the needs of continuous modification of contemporary electronic equipment. Due to the low noise durability of toroidal transformers, many manufacturers use them for high-fidelity audio equipment and video display terminals, power amplifiers, electronic testers and general equipment.
