1 ввод с газовой изоляцией
ввод с газовой изоляцией
Ввод, в котором основной изоляцией является газ (отличающийся от окружающего воздуха) под давлением, большим атмосферного или равным ему.

gas-insulated bushing
bushing in which the major insulation consists of gas (other than ambient air) at atmospheric pressure or higher
NOTE 1 This definition includes bushings which are intended to form an integral part of gas-insulated equipment, the gas of the equipment being in communication with that of the bushing.
NOTE 2 A bushing which contains solid insulating materials other than the envelope containing the gas (e.g. support for conducting layers or insulating cylinder), is a combined insulation bushing (see 3.13).
NOTE 3 A bushing in which the desired voltage grading is obtained by an arrangement of conducting or semi-conducting layers incorporated in an insulating material (e.g. plastic film) is referred to as a gas insulated condenser graded bushing.

traversée à isolation gazeuse
traversée dont l'isolation principale est assurée par un gaz (autre que l'air ambiant) à une pression supérieure ou égale à la pression atmosphérique
NOTE 1 Cette définition comprend les traversées destinées à faire partie intégrante d'une installation à isolation gazeuse où le gaz de l'installation est en communication avec celui de la traversée.
NOTE 2 Une traversée qui comporte des matériaux isolants solides autres que l'enveloppe contenant le gaz (par exemple un support pour des couches conductrices ou un cylindre isolant) est une traversée à isolation composite (voir 3.13).
NOTE 3 Une traversée dans laquelle la répartition de tension souhaitée est obtenue par la disposition de couches conductrices ou semi-conductrices incorporées au matériau isolant (par exemple film plastique) est désignée par une traversée à isolation gazeuse à répartition capacitive.

2 загрязнение (в электробезопасности)
загрязнение
Присутствие инородного вещества: твердого, жидкого или газообразного (ионизированные газы), - которое может вызвать уменьшение диэлектрической прочности или поверхностного сопротивления.
[ ГОСТ Р 52319-2005( МЭК 61010-1: 2001)]
загрязнение
Любое добавление инородных веществ, твердых, жидких или газообразных (ионизированных газов), которые могли бы уменьшить электрическую прочность изоляции или удельное сопротивление поверхности.
[ ГОСТ Р 50030. 1-2000 ( МЭК 60947-1-99)]EN
pollution
any condition of foreign matter, solid, liquid or gaseous (ionized gases), that may affect dielectric strength or surface resistivity
[IEC 60947-1, ed. 5.0 (2007-06)]
pollution
any addition of foreign matter, solid, liquid or gaseous that can produce a permanent reduction of dielectric strength or surface resistivity of the insulation
NOTE – Ionized gases of a temporary nature are not considered as to be a pollution.
[IEV number 442-01-28]
contamination
the first is defined as area and the second as particulate. The first is caused by surface contaminants that cannot be removed by cleaning or are stained after cleaning. Those may be foreign matter on the surface of, for example a localized area that is smudged, stained, discoloured, mottled, etc., or large areas exhibiting a hazy or cloudy appearance resulting from a film of foreign materials
[IEC 62276, ed. 1.0 (2005-05)]FR
pollution
tout apport de matériau étranger solide, liquide ou gazeux (gaz ionisés) qui peut entraîner une réduction de la rigidité diélectrique ou de la résistivité de la surface
[IEC 60947-1, ed. 5.0 (2007-06)]
pollution
tout apport de matériau étranger solide, liquide ou gazeux qui peut entraîner une réduction permanente de la rigidité diélectrique ou de la résistivité de surface de l'isolation
NOTE – Les gaz ionisés de nature fugace ne sont pas considérés comme une pollution.
