Description

Дл  контрол  повреждений и неоднородностей толщины изол ционного покрыти  на электрических проводах примен ют устройства, основанные на использовании емкостных датчиков.Devices based on the use of capacitive sensors are used to control the damage and irregularities in the thickness of the insulation coating on electrical wires.

В этих устройствах емкость создаетс  между металлом провода и провод пц,:им электрический ток жидким или сыпучим веш,еством, заполн ющим ванну, через которую пропускают исследуемый провод.In these devices, a capacitance is created between the metal of the wire and the pc wire,: an electrical current to them is liquid or bulk suspended, filling the bath through which the test wire is passed.

Согласно изобретению, предлагаетс  применить подобное устройство дл  измерени  среднего значени  толщины изол ции участка провода , наход щегос  в ванне.According to the invention, it is proposed to use a similar device for measuring the average value of the insulation thickness of a wire section in a bath.

На фиг. 1 показана принципиальна  схема предлагаемого устройства , а на фиг. 2 - схема его датчика.FIG. 1 is a schematic diagram of the proposed device, and FIG. 2 is a diagram of its sensor.

Устройство содержит два емкостных датчика 1 vi 2, через которые прот ги-ваетс  контролируемый провод, и измеритель емкости 3, щкала которого проградуирована в единицах толщины изол ции. При измерени х провод сматываетс  с катущки 4 и наматываетс  на катущку 5.The device contains two capacitive sensors 1 vi 2, through which a monitored wire is passed, and a capacitance meter 3, the scale of which is calibrated in units of insulation thickness. In measurements, the wire is wound from the roller 4 and wound on the roller 5.

Датчик представл ет собой латунную ванну 6 из латуни, в которую наливаетс  электропроводна  жидкость 7, например, ртуть. Поверхность ртути заливаетс  слоем спирта 8 или другого жидкого диэлектрика, чтобы исключить возможность испарени  ртути из ванны. Сверху ванна закрываетс  крыщкой 9. Контролируемый провод 10 проходит через ртуть по роликам //.The sensor is a brass bath 6 made of brass, into which electrically conductive liquid 7 is poured, for example mercury. The surface of the mercury is poured with a layer of alcohol 8 or another liquid dielectric to eliminate the possibility of mercury evaporation from the bath. On top of the bath is closed by a cap 9. The controlled wire 10 passes through the mercury through the rollers //.

Примен   два одинаковых емкостных датчика, осуществл ют емкостный контакт с проводом и определ ют величину емкости на провер емом участке провода. По полученным результатам легко определ ют толщину изол ции на основании формулы плоского конденсатора.Apply two identical capacitive sensors, make capacitive contact with the wire and determine the capacitance value on the tested section of the wire. Based on the results obtained, the thickness of the insulation is easily determined on the basis of the formula of a flat capacitor.
