Embodiment 1

[0042] Embodiment 1: A maintenance method for a rotating antenna, comprising the following steps:

[0043] Step 1: Monitoring the structural parameters of the antenna;

[0044] Step 2: Detect the electrical parameters of the antenna feeder;

[0045] Step 3: Replace and debug the ATU capacitor;

[0046] Step 4: Test and adjust the parameters of the rotating antenna control system;

[0047] Step 5: Check the meshing clearance and axial parallelism of the driving and driven gears.

Embodiment 2

[0048] Embodiment 2: Further, this embodiment provides a further detailed description of the structural parameters of the antenna, that is, the structural parameters of the monitoring antenna include mast verticality ≤ 1 / 1000, platform horizontality ≤ 1 / 750, vibrator surface Vertical deviation ≤ 5 / 1000, vibrator unevenness deviation ≤ 1.5 / 100;

[0049] In addition, the anti-corrosion coating maintenance of the antenna steel structure is also particularly important. The coating is to paint the old mast for anti-corrosion. The time interval for painting is not less than 48 hours, and the dry film thickness of each layer is randomly checked with a paint film thickness gauge, and the dry film thickness of each layer is at least 80 μm; before installation, use angle grinding for surface defects, such as scaling and skin peeling. Machine or 120 sandpaper to smooth. Clean the surface of the oily component with an organic solvent until it is free of oil, water and dirt. .

Embodiment 3

[0050] Embodiment 3: Further, the electrical parameters of the antenna feeder include azimuth deviation≦±2°, standing wave ratio≦1.2, wave angle difference≦6°, grounding resistance≦4Ω, feeding efficiency≧85%, insulator insulation Degree ≧ 2000Vdc / cm.

The method of the invention has the advantages of convenient operation, significant effects and strong practicability.

Description

technical field [0001] The invention belongs to the field of antenna maintenance, in particular to a maintenance method for rotating antennas. Background technique [0002] The high-power short-wave rotating antenna has the characteristics of high efficiency, maneuverability, flexibility and wide coverage. The number of new rotating antennas in my country is increasing, and the utilization rate and tasks of the antenna are also increasing, which increases the maintenance workload of the rotating antenna system; as Due to the high integration of the system and the complicated maintenance of this type of antenna, there is currently no good and standard maintenance method, which cannot guarantee and improve the maintenance quality of the antenna feeder operation system, and cannot ensure the reliability of the rotating antenna feeder. run. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a maintenance method that can incre...
