Tube body flow identification method of combined type klystron arrays

Abstract

A tube body flow identification method of combined type klystron arrays comprises a klystron arrays with a plurality of klystron tubes, a cathode of each klystron tube is connected with a cathode of a high voltage power supply, a collector of each klystron tube is connected with an electric current transducer, the electric current transducer receives a klystron array tube body current and inputs the klystron array tube body current into a signal disposal module through a coaxial line, a signal after being disposed is export to a threshold value identifying module, the threshold value identifying module further disposes the signal to obtain the signal which can be received by a controlling comparator, the threshold value identifying module selects an identifying algorithm to dispose the signal according to a system operating mode, the result is sent to a decision-making board to conduct a multichannel decision-making algorithm calculation, the calculation result is taken as a feedback for the threshold value identifying module of each channel again, the decision that identifying results of which channel can be send to a protection board is assured, and a driving protection board selects a locking mode of the high voltage power supply connected with the driving protection board according to system safety level requirements. The tube body flow identification method of the combined type klystron arrays can timely and effectively distinguish troubles on a klystron and make sure the system operate steady.

Description

Technical field: [0001] The invention relates to an overcurrent identification method, in particular to a combined klystron array tube body overcurrent identification method. Background technique: [0002] In order to improve the overall output power capability of the microwave system, the high-power centimeter-wave system often adopts a parallel connection method, and multiple klystrons are reasonably combined to obtain megawatt-level or even higher output power. One of the characteristics of the klystron, the core device in the system, is that internal ignition will inevitably occur, which will cause overcurrent in the klystron body. For this fault state, immediate and effective protection measures should be adopted to ensure that the energy input is cut off when the ignition energy does not cause damage to the klystron. When multiple tubes are connected in parallel, the phenomenon caused by this fault will be very complicated. Currently, the solution to this problem i...

Problems solved by technology

This approach can neither distinguish which klystron has an overcurrent fault, so that it can be dealt with in a targeted manner; it also makes the microwave output energy interrupted, affecting the steady-state operation of the system
