Abstract
The invention provides a novel helix protection method for a domestic travelling wave tube amplifier. The method comprises the following steps: a helix protection socket way is adopted; and a helix protection state and a helix non-protection state are set as required for different ground testing process and orbit operation process in the helix protection socket way. By the method, the helix protection state and the helix non-protection state can be switched conveniently. The method has been applied to a domestic travelling wave tube amplifier of X wave band range in a satellite digital transmission system transmitter.
Description
Technical field
The present invention relates to travelling-wave tube amplifier, particularly, relate to novel homemade travelling-wave tube amplifier spiral shell stream guard method and device.
Background technology
Data transmission subsystem transmitter power amplifier level is mainly accomplished and the satellite payload data is carried out functions such as power amplification, filtering; Be that satellite is realized one of core unit that star ground number passes; Travelling-wave tube amplifier is the chief component of power amplifier level; The function of travelling-wave tube amplifier mainly is to realize the power amplification of radio frequency model, to realize the reliable star ground transmission of satellite data.
Along with the raising of star ground message transmission rate, transmitting power increases thereupon on the required star.Travelling-wave tube amplifier is low with its broadband, high-gain, noise, the efficient advantages of higher obtains use more and more widely.In recent years, along with steadily improving of China's technological progress and technological level, the production domesticization work of travelling-wave tube amplifier has stepped important paces, and technology is comparatively ripe, has possessed the condition of using at rail.Under the support energetically of higher authorities and department, the power amplifier of homemade X-band travelling-wave tube amplifier as data transmission subsystem transmitter A machine adopted in certain satellite decision, to advance the production domesticization work of travelling-wave tube amplifier.
Generally speaking, in the ground experiment stage, for preventing to cause travelling wave tube operation irregularity travelling wave tube to sustain damage because of misoperation or other reasons, the power amplifier level is set to spiral shell and flows protected state; Stage in orbit, aging along with travelling wave tube, the spiral shell flow valuve can be increasing, even surpass limit value, but but travelling wave tube this moment operate as normal still, institute thinks the useful life that prolongs travelling wave tube, the stage travelling wave tube is set to spiral shell and flows not protected state in orbit.
Owing to be uses of broadcasting TV programs by satellite for the first time of this wave band travelling-wave tube amplifier, but experience for reference is few, lacks at rail to use data, therefore guarantees normally in the rail application and becomes a research content useful life.
Summary of the invention
No matter be homemade or the import travelling-wave tube amplifier, its operating state all has the protected and not protected two states of spiral shell stream.Wherein, the spiral shell of import travelling-wave tube amplifier stream protected with spiral shell stream not the setting or the switching of protected state be to realize through the multi-tap on the EPC, when connecting the type multi-tap, travelling-wave tube amplifier is in spiral shell and flows protected state; After pulling out this socket, travelling-wave tube amplifier is in the not protected state of spiral shell stream.There is not the type multi-tap at present.Spiral shell how to realize travelling-wave tube amplifier quickly and easily flow protected state and spiral shell stream not protected state be switching to a problem demanding prompt solution.
In order to reach the foregoing invention purpose, the method for designing that the present invention is adopted for its technical problem of solution is to flow not to homemade space travelling wave tube amplifier spiral shell stream guard mode and spiral shell that the switching mode of guard mode designs and innovates.
According to an aspect of the present invention, a kind of homemade travelling-wave tube amplifier spiral shell stream guard method of novelty is provided, comprises the steps:
Adopt the mode of spiral shell stream protection socket,, carry out the switching between the protected and not protected two states of spiral shell stream according to ground test mode and needs in orbit.
Preferably, the mode of said employing spiral shell stream protection socket comprises the steps:
The EPC socket is carried out shunt, and the lead that whether decision is carried out the protection of spiral shell stream leads to separately on one first socket, and is that first socket outfit spiral shell stream is not protected plug.
Preferably, the said switching of carrying out between the protected and not protected two states of spiral shell stream comprises the steps:
Through spiral shell stream is not protected plug insertion socket, make travelling-wave tube amplifier be in the not protected state of spiral shell stream;
Do not protect plug through pulling out this spiral shell stream, make travelling-wave tube amplifier be in spiral shell and flow protected state.
According to another aspect of the present invention, the method for operation of travelling-wave tube amplifier in a kind of satellite is provided, comprises the steps:
Before satellites transmits, insert spiral shell stream and do not protect plug, make travelling-wave tube amplifier be in the not protected state of spiral shell stream.
According to a further aspect of the invention, a kind of homemade travelling-wave tube amplifier spiral shell stream protective device of novelty is provided, comprises that EPC socket, first socket and spiral shell stream do not protect plug, wherein, said
Determine the lead that whether carries out the protection of spiral shell stream to lead to separately on said first socket in the said EPC socket, be equipped with said spiral shell stream on said first socket and do not protect plug.
According to a further aspect of the invention, a kind of satellite of novelty is provided, comprises homemade travelling-wave tube amplifier spiral shell stream protective device according to said novelty provided by the invention.
Embodiment
Homemade travelling-wave tube amplifier spiral shell stream guard method according to novelty provided by the invention; Particularly, in the ground test process, switch between the protected and not protected state of spiral shell stream at spiral shell stream as required; After spiral shell stream is not protected plug insertion socket; Travelling-wave tube amplifier is in the not protected state of spiral shell stream, does not protect plug when pulling out this spiral shell stream, and travelling-wave tube amplifier is in spiral shell and flows protected state.In the process, travelling-wave tube amplifier is the not protected state of spiral shell stream in orbit.Therefore, before satellites transmits, insert spiral shell stream and do not protect plug, make travelling-wave tube amplifier be in the not protected state of spiral shell stream.
The method of operation of travelling-wave tube amplifier in the satellite according to the present invention comprises step: before satellites transmits, insert spiral shell stream and do not protect plug, make travelling-wave tube amplifier be in the not protected state of spiral shell stream.
