ABB T60407-B4803-X010 3BHB004719R0001 PULSE TRANSFORMER

ABB's 3BHB004719R0001 pulse transformer has specific applications and functions under model T60407 - B4803 - X010. Here is some information about it:

Function and principle

Function: Pulse transformers are mainly used to transform electrical pulse signals, which can achieve functions such as signal isolation, amplification, and voltage or current conversion. In industrial control systems, they are often used to convert low-power pulse signals generated by control circuits into high-power pulse signals suitable for driving loads, such as driving motors, relays and other equipment.

Principle: Based on the principle of electromagnetic induction, the primary winding and the secondary winding are coupled together through the iron core. When a pulse current passes through the primary winding, an alternating magnetic field is generated, which induces corresponding pulse voltage and current in the secondary winding, thereby realizing the transmission and conversion of electrical pulse signals.

Technical parameters

Working voltage: It usually needs to be determined according to the specific application scenario and the supporting equipment. It is generally clearly marked in its specification manual, which may range from tens of volts to hundreds of volts.

Pulse frequency: The frequency range of pulse signals that can be processed is also one of its important parameters. Different applications have different requirements for pulse frequency. The transformer may be suitable for pulse signals with a frequency of tens of Hz to tens of kilohertz or even higher.

Transformation ratio: The ratio of the number of turns of the primary winding to the number of turns of the secondary winding. It determines the voltage transformation multiple and current transformation multiple of the pulse transformer for the signal. The specific transformation ratio value will be designed and adjusted according to the actual application requirements.

Insulation performance: It has good insulation performance to ensure that there will be no leakage or short circuit between the primary and secondary windings and between the windings and the iron core under high voltage and high frequency working conditions. Usually, there are related indicators such as insulation resistance and withstand voltage level to measure its insulation performance.

Application scenario

Industrial automation control system: In the automated production line, it is used to drive various actuators, such as motors, solenoid valves, etc., to achieve precise control of the production process. For example, on the assembly line of an automobile manufacturing plant, the action of the robot can be controlled to enable it to accurately complete tasks such as welding and handling.

Power electronic equipment: In power electronic equipment such as frequency converters and inverters, it is used to amplify the pulse signal generated by the control circuit and transmit it to the power switching devices (such as IGBT, MOSFET, etc.), control the conduction and shutdown of these devices, and thus realize the conversion and control of electric energy.

Measurement and detection system: In some measurement and detection equipment, weak pulse signals can be amplified and isolated for subsequent signal processing and analysis. For example, in the sensor detection circuit, the weak pulse signal output by the sensor is amplified to a level suitable for collection and processing.
