HVA-1 Application Field and Working Principle

The HVA-1 device is an extruded film high voltage arrester (HVA). It is mainly used in high voltage applications for the protection of power transistors and other components against overvoltages, secondary lightning, and transient overvoltage events. It has a large capacitance with low impedance, providing superior protection for electronics and semiconductor components.

The HVA-1 device works on the principle of combining the power handling capabilities of a low pass filter with the high voltage protection characteristics of a gas discharge tube. This combination creates a unique protective device that can provide protection from transient overvoltages, lightning strikes, and other high voltage events. The HVA-1 device is not only used in high voltage applications, but can also be used in any application where rapid re-connection of power supplies is required.

Applications

The HVA-1 device is designed to provide protection from overvoltage events and transient spikes. It is ideal for applications such as power supplies, industrial automation systems, automotive applications, and even high voltage protection in train applications.

The device offers a high level of protection for critical applications, and can be used in a wide range of operating temperatures, and offers superior noise immunity and surge protection, even in extreme conditions. The HVA-1 device is ideal for applications where high speed switching is required, as it can pump large amounts of power quickly and safely from the source to the output.

Working Principles

The HVA-1 device is based on a combination of an oxygen arc arrestor and a high voltage protection circuit. The device is designed to allow very fast overcurrent protection, even when the current exceeds the device’s rated peak current peak. The device is also designed to absorb any load on the protected circuit by using current limiting and shorting elements. This ensures that any overvoltage event is quickly and safely dissipated without the need for an overcurrent circuit.

When a voltage transient occurs, the device quickly opens a gap between the upper and lower contacts. This creates an air gap that quickly dissipates the energy from the transient and allows normal operation to resume. The device is designed to remain open until the voltage reaches a predetermined level, at which point it closes and allows current to flow.

The device is also designed to provide high voltage isolation between the source and the electronics being protected, which helps to minimize the risk of damage to sensitive components. The device is designed to work with a wide range of voltages, currents, and loads, making it highly versatile for many high voltage applications
