Abstract

The invention relates to a multi-channel high-power klystron overcurrent real-time protection device with online self-checking function. The device comprises a klystron, a filament is arranged in the klystron, the two ends of the filament are connected to a filament transformer through a wire, the filament transformer is connected with a filament power supply through a wire, wires are respectively led out from the collector connecting terminal and the tube body connecting terminal of the klystron, the wire led out form the tube body connecting terminal is grounded after penetrating a hall sensor I , and the wire led out form the collector connecting terminal is grounded after penetrating a hall sensor II; one end of the filament is connected to the HVPS cathode through a current limiting resistor, the HVPS anode is grounded, and the output terminal is connected with a tommy bar through a wire; wires are respectively led out from the hall sensor I and the hall sensor II are connected to the respectively corresponding output terminals of the overcurrent protection circuit, and the signals of the hall sensors are input to the overcurrent protection circuit through wires. The invention works well in the 2.45G high-power low-hybrid wave system, can fully realize all the functions and has greatly enhanced reliability and stability at the same time.

Description

technical field [0001] The invention relates to the field of klystron protection, in particular to a multi-channel high-power klystron overcurrent real-time protection device with an online self-check function. Background technique [0002] The klystron is the core component of the high-power microwave system and its price is very expensive. Its normal operation is directly related to the safety of the entire system. The fault state of the klystron when it is powered on at high voltage shows two forms of overcurrent: tube body overcurrent and main circuit overcurrent. Because the klystron (remove the word "possible") is in an extremely dangerous state during overcurrent, the high pressure needs to be withdrawn in time, otherwise the klystron will be damaged. The defocusing of the magnetic field of the klystron, the vacuum problem in the tube, or the processing defect may cause the leakage current of the tube body to be too large. At this time, the amount of joules released ...
