This is the warship is undertaking degauss works, it is the necessary step before all warships and submarine leave factory. Of course, the naval ships of enlistment also can undertake degauss works regularly.
We know the earth is a big magnetic field, compass can indicate direction so is the action because of geomagnetic field. Naval ships basically is made by iron and steel and other metal stuff and become, itself is ferromagnetic material, waited for underwater time to grow, the influence of magnetic field standing the ground, flap plus water billow and oneself interior is run mechanically, it can contain very strong magnetic as a result to also can form a fixed magnetic field at itself.
First homebred aircraft carrier hangs plumb-line cable to undertake degauss works
This one characteristic hair of the warship understands German basis magnetic mine, this kind of mine can be in get after the influence of naval magnetic field, rotational magnetic needle detonates mine and unlike tradition mine needs a warship to spark in that way. Period of World War II, german use magnetic mine blast to become allied forces vessel of more than 1000 ship. The progress of modern science and technology, the weapon in all sorts of magnetic water and magnetism go instead equipment sort is various, be in the light of this one crude character of naval ships design, was thought to come true " magnetism concealed body " , naval naval vessels is necessary to undertake fixed degauss in enlistment.

Traditional degauss exercise wants a course to measure magnetism, circle cable, degauss, measure wait for measure. The size of alleged the magnetic field that measures magnetism to measure naval ships namely, affirmatory magnetic field; Circle cable to use cable to twine naval ships namely rise form coil, the result is we see on graph warship " 5 flowers are bound greatly " appearance; Degauss is online cable after been circle, electrify undertakes degauss works, the magnetic field that produces through coil will change the fixed magnetic field of naval ships; Final measurement is to ensure the magnetism of ship system is counteracted for neuter, contain magnetism no longer.

Boat of fixed degauss station, degauss is should make naval ships and boat core, it is through twining outside ship system " 5 flowers are bound greatly " the electrify coil of type undertakes degauss works. This kind of means is more time-consuming, and ask to field taller -- must choose to undertake in period of time of calm berth, slack tide, encounter sea condition change is frequent, the degauss task of a naval ships lasts 10 days constantly half moon.
Homebred and new-style car carries degauss station
New-style car carries degauss station technology to be able to be in fall without landing requirement round-the-clock launch degauss operation, moor afloat frigate naval vessel Shou and naval vessel Wei are soldered respectively cable connector, again degauss cable ordinal enter Wei of naval vessel Shou repeatedly, connection of other one aspect of the matter comes degauss supply vehicle, can spread out to measure magnetism and electrify degauss automatically, and classics is compositive the installation after optimizing carries degauss equipment in the car in standard container, can embark to go up in the sea by landing boat undertake degauss. Early 2013 homebred and new-style car carries degauss to stand to already listed outfit admiralty team, also be made up for the inadequacy in this one domain.
