Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0037] The three-component sensor on the space-borne magnetic field fluctuation analyzer of the present invention is mainly made up of 9 kinds of parts, and they are: rod-shaped magnetic core 2, bobbin 1, solenoid coil, sleeve pipe 13, positive for fixing sleeve pipe 13 Hexahedral frame 12, aluminum bracket 14, heat insulating film cover 8, plug connector 9 and heat insulating film ground wire.

[0038] Three groups of solenoid-shaped induction coils representing the three wave components are tightly wound on the bobbin 1 with a length-to-diameter ratio of about 23:1. The total length of the bobbin 1 is 275 mm. The rod-shaped magnetic core 2 made is completely inserted into the inner hole 6 of the bobbin 1, and then the bobbin 1 with the coil wound is inserted into and packaged in the casing 13, and the four lead wires of the induction coil and...

Abstract

The invention discloses a three-component sensor for satellite magnetic field fluctuation analyzer, including three core rod, thread spool, coil, hexahedral framework, aluminum frame, insulation film jacket, connectors and the earth wire insulation film. The described hexahedral framework has three pairs of orthogonal screw hole, inserted into the above thread spool core rod. Thread spool around the outer surface of a solenoid coil form, in the form of solenoid coil outside a set of packaging, three casing is inserted into hexahedral framework of the three pairs of thread hole to fix. The above alumni frame is installed under the hexahedral framework. The hexahedral framework is connected to the satellite magnetic field fluctuations analyzer. The above insulation film is wrapped in the casing and outside the hexahedral framework. The advantages of the present invention include the various components and the overall structure of high strength, affordable bad launching vibration, reasonable structure, from the simple processing machines, mechanical error is small; for the bad environment.

Description

technical field [0001] The invention relates to a sensor antenna of a space science satellite magnetic field fluctuation analyzer, in particular to a three-component sensor of a space-borne magnetic field fluctuation analyzer installed on the sensor antenna on the top of a special extension rod extending out of the satellite body. Background technique [0002] Due to the high sensitivity of the spaceborne magnetic field fluctuation analyzer, its sensor antenna needs to be far away from interference sources, especially the equipment interference of satellite stars, so the on-board sensor antenna is usually installed on a long extension rod vertically protruding from the surface of the satellite body. top. For example, the sensor antennas of the CLUSTER II satellite launched by ESA in 1997 and the magnetic field fluctuation analyzer (STAFF) on the Double Star TC-1 launched by China-EU cooperation in 2003 are all installed on the top of the boom about 3 meters away from the sur...
