What is a Klystron Tube？


Klystron Definition


A Klystron is a vacuum tube used to amplify or oscillate microwave signals, important in various high-frequency applications.




Operating Principle


Klystrons work by modulating the velocity of an electron beam within a vacuum tube to generate microwave energy.


 

 

Applications


Klystrons are essential in devices like RADAR systems, radio receivers, and microwave transmitters.


 

Technical Specifications


Klystrons operate across a broad range of frequencies and power outputs, with efficiency levels suitable for specialized applications.


 

Types of Klystron

Causes and Preventive Measures of Fire and Explosion in Oil Circuit Breakers
Causes and Preventive Measures of Fire and Explosion in Oil Circuit Breakers
Causes of Fire and Explosion in Oil Circuit Breakers When the oil level in an oil circuit breaker is too low, the oil layer covering the contacts becomes too thin. Under the effect of the electric arc, the oil decomposes and releases flammable gases. These gases accumulate in the space beneath the top cover, mixing with air to form an explosive mixture, which can ignite or explode under high temperature. If the oil level inside the tank is too high, the released gases have limited space to expan

How Vacuum Tech Replaces SF6 in Modern Ring Main Units
Ring main units (RMUs) are used in secondary power distribution, directly connecting to end-users such as residential communities, construction sites, commercial buildings, highways, etc.In a residential substation, the RMU introduces 12 kV medium voltage, which is then stepped down to 380 V low voltage through transformers. The low-voltage switchgear distributes electrical energy to various user units. For a 1250 kVA distribution transformer in a residential community, the medium-voltage ring m

Why Monitoring Accuracy Matters in Power Quality Systems
The Critical Role of Monitoring Accuracy in Power Quality Online DevicesThe measurement accuracy of online power quality monitoring devices is the core of the power system’s “perception capability,” directly determining the safety, economy, stability, and reliability of power supply to users. Inadequate accuracy leads to misjudgment, incorrect control, and flawed decision-making—potentially causing equipment damage, economic losses, or even grid failures. Conversely, high accuracy enables precis
