The purpose of pulse transformer
Pulse transformer is a special type of transformer mainly used for protection devices in power systems and catalyst triggering circuits in power equipment.
In the power system,the main function of transformers is to transmit electrical energy from one level of power lines to another.Pulse transformers are used to generate specific pulse signals to protect against faults in the power system.In protective devices,pulse transformers can generate specific pulse signals to control the operation of protective relays.Meanwhile,pulse transformers can also be used to detect grounding faults in power systems,ensuring the safe and stable operation of the power system.
In power equipment,pulse transformers are mainly used to control the switching of catalyst triggering circuits.Catalyst triggering circuit refers to the use of high-voltage pulses generated by gas discharge to trigger the discharge tube for conduction.Pulse transformers are used to generate high-voltage pulse signals required for triggering circuits,ensuring the normal operation of power equipment.
Working principle of pulse transformer
Pulse transformers can generate high voltage,short duration pulse signals,and their working principle is based on the characteristics of self inductance and mutual inductance.When a sudden pulse current passes through one side of the transformer,a brief high voltage signal is generated.This signal varies with the number and proportion of windings in the transformer.
When the pulse signal generated by one side of the transformer reaches the other side of the transformer,it will be converted into a pulse voltage signal.The amplitude,width,and rise and fall time of this pulse voltage signal are all related to the number and proportion of windings in the transformer.
In short,a pulse transformer is a special type of transformer that can generate high voltage,short duration pulse signals.It is mainly used for protection devices in power systems and catalyst triggering circuits in power equipment.Due to its efficient and reliable characteristics,pulse transformers are becoming increasingly widely used in the field of power.
Pulse transformer is a specially designed transformer mainly used for processing and generating pulse signals.Its function is as follows:
Generate specific pulse signals to perform specific functions.For example,in the power system,it is used to generate pulse signals for controlling and protecting relays in protective devices,or to detect ground faults to ensure the safe and stable operation of the power system.
Control the switch of the catalyst triggering circuit.In power equipment,pulse transformers are used to generate high-voltage pulse signals required for triggering circuits,ensuring the normal operation of power equipment.
Used in the fields of radar and exchange technology.In these applications,pulse transformers are used for signal transmission,voltage conversion,impedance matching,DC isolation,polarity conversion,etc.
Energy storage.When there is no output in the primary input current,the magnetic core converts the input current into magnetic storage,and when the input current is cut off,it releases the induced current output on the winding.
Voltage conversion and isolation.For example,in the high-voltage package of a cathode ray tube television,a significant increase in voltage is achieved through primary isolation.
In addition,pulse transformers are widely used in high-power pulse technology and accelerator research,playing a role in impedance matching and power regulation.
