Embodiment Construction

[0009] The working state of the traveling wave tube amplifier is divided into two states: the spiral current is protected and the unprotected state. Usually, in the ground test stage (before launch) to prevent accidents (wrong wiring or operation error), the spiral current of the traveling wave tube amplifier is in the protected state. Protected state, and unprotected state when running in orbit.

[0010] Whether the spiral current is protected or not is determined by the connection status between pin 15 and pin 19 of the DCMA-37 core socket on the EPC. When pin 15 and pin 19 are in an open state, the spiral current is protected; otherwise, when pin 15 When it is short-circuited with pin 19, the spiral current is not protected.

[0011] Such as figure 1 Shown is the spiral flow protection state of the traveling wave tube, that is, the protection plug is directly inserted.

[0012] Such as figure 2 As shown, during the ground test, in the safe use method provided by the pre...

Abstract

The invention discloses a safe use method of a satellite-loaded travelling wave tube. An adapter plug seat is installed on the travelling wave tube and then a protective plug is inserted, and the jack thrusting needles of the 15th pin and 19th pin of the adapter plug seat are removed; the adapter plug seat is installed on the ground test stage, and the travelling wave tube swirling flow is in a protective state; and before a satellite executes a flying task, the adapter plug seat is pulled out, the 15th pin and 19th pin are connected through a connection line on the adapter plug seat, and the travelling wave tube swirling flow is in a normal protective state. By the method in the invention, the safe use of the satellite-loaded travelling wave tube can be conveniently and reliably achieved.

Description

technical field [0001] The invention relates to a method for safely using a space-borne traveling wave tube. Background technique [0002] my country's polar-orbiting meteorological satellites are used to realize global, all-weather, three-dimensional, quantitative remote sensing. Its digital transmission system uses an X-band traveling wave tube amplifier as a form of radio frequency signal amplification. The traveling wave tube is imported from Thales, France with a specification of 45W, and is a valuable component. In order to ensure the safety of the testing process on the ground and prevent damage to the traveling wave tube caused by human error, the designer cleverly designed the adapter socket so that the spiral flow of the traveling wave tube can be protected during the ground testing, thus ensuring The use of traveling wave tube is safe. The design method is simple to operate and has high circuit reliability. [0003] At present, traveling wave tube amplifiers ha...
