EI19 Low Frequency Transformer Horizontal Power Supply Current Transformer

1.Product Description

The EI19 Power Supply Current Transformer is a crucial electrical component designed for power supply applications. Featuring an EI19 core structure, this current transformer offers a combination of efficient magnetic performance and a compact form factor. The "EI" shape of the core provides a closed magnetic path, which helps to minimize magnetic leakage and enhance the transfer of magnetic flux, ensuring reliable current transformation.

In power supply systems, its primary function is to accurately measure and monitor the current flowing through the circuit. By stepping down the current to a more manageable level, it allows for easy connection to measurement devices such as ammeters, current sensors, or control circuits. This enables precise monitoring of the electrical load, helping to prevent overcurrent situations and ensure the safe and efficient operation of the power supply.

Constructed with high-quality materials, the EI19 Power Supply Current Transformer is built to withstand various operating conditions. It can handle a wide range of input currents and is designed to provide stable and accurate performance over an extended period. Its robust design also makes it resistant to electrical and mechanical stresses, ensuring long-term reliability.

Whether used in industrial power supplies, renewable energy systems, or electronic equipment, the EI19 Power Supply Current Transformer plays a vital role in maintaining the integrity of the power supply circuit. Its ability to accurately measure and transform current makes it an essential component for effective power management and protection, contributing to the overall stability and efficiency of the electrical system.

1. Core: Adopting EI type core structure, which is also the origin of its name. Usually made of magnetic materials with high permeability, such as silicon steel sheets or ferrites. The EI type iron core can provide a good magnetic circuit, concentrate the magnetic flux, reduce magnetic leakage, and improve the performance of the transformer. The shape and size of the iron core (where "19" may represent a certain specification parameter of the iron core) determine the magnetic properties and applicable current range of the transformer.

2. Primary winding: It is the part of the current transformer connected to the tested circuit, directly carrying the high current of the main circuit. The number of turns in a primary winding is relatively small, and it is usually designed based on the rated current and the current carrying capacity of the winding. Its wires are generally thicker to meet the requirements for passing high currents. The structure and number of turns configuration of a primary winding will affect the transformation ratio and measurement accuracy of the transformer.

3. Secondary winding: Connected to measurement, protection, and control equipment, it converts the high current on the primary side into a small current proportionally. The secondary winding has more turns and the wires are relatively thin. The output current signal (usually standard values such as 5A or 1A) can be used for subsequent measurement and analysis by instruments, or for triggering protective devices. The design of secondary winding needs to consider the matching with different devices and the impact on measurement accuracy.

4. Insulation materials: Due to the need to maintain electrical insulation between the primary and secondary windings, as well as between them and the iron core, to ensure safe operation and prevent signal interference, various insulation materials are used. These insulation materials include insulation paint, insulation paper, epoxy resin, etc., which can withstand a certain voltage and have good mechanical properties and chemical stability, ensuring long-term reliable operation in different working environments.

5. Shell: It serves to protect the internal windings and iron core, while also providing some mechanical support. The casing is usually made of materials such as plastic and metal, with a protection level that can prevent dust, moisture, and impact, ensuring the normal operation of the transformer under various harsh environmental conditions.

6. Wiring terminal: used to connect the external circuit of the primary winding and the secondary winding. The primary side terminal block is used to connect to the main circuit, while the secondary side terminal block is used to connect measurement, protection, and other equipment. The design of wiring terminals should ensure good electrical connection and mechanical stability, and prevent problems such as looseness and poor contact.

2.Electrical Performance

Electrical Performance	Description
Current Transformation Ratio	The EI19 Power Supply Current Transformer has a specific current transformation ratio that accurately steps down the high current in the primary circuit to a measurable low current in the secondary circuit, such as converting large primary currents (e.g., hundreds or thousands of amperes) to standard secondary currents like 5A or 1A for easy measurement and control.
Accuracy Class	It is classified according to its accuracy level, which indicates the degree of deviation between the actual secondary current output and the ideal value corresponding to the primary current. Higher accuracy classes ensure more precise current measurement, suitable for applications where accurate current monitoring is crucial, like in power metering and precision control systems.
Rated Current	The rated primary and secondary currents are defined values within which the transformer can operate reliably. The rated primary current determines the maximum current the transformer can handle in the primary circuit, while the rated secondary current is the standard output current for measurement and connection to other devices. Operating within the rated current range maintains the transformer's performance and lifespan.
Insulation Resistance	With proper insulation materials between the primary and secondary windings, as well as between the windings and the core, the transformer has a high insulation resistance. This resistance value prevents electrical leakage and ensures the safety of the secondary circuit and connected devices from the high voltage of the primary circuit. It also helps in reducing electromagnetic interference between the two circuits.
