Description

(54) ИЗОЛЯЦИОННОЕ МАСЛО(54) INSULATING OIL

Известно изол ционное масло на основе минерального масла с добавлением присадкиарилоксисилоксана . Указанна  присадка повышает электрическую прочность масла, но имеет недостаточную термоокислительную стабильность.A mineral oil based insulating oil with the addition of an aryloxysiloxane additive is known. This additive improves the electrical strength of the oil, but has insufficient thermo-oxidative stability.

С целью устранени  указанного недостатка в состав предлагаемого масла в качестве присадки введен диэфир ортокремниевои кис- лоты формулыIn order to eliminate this drawback, a diester orthosilicic acid of the formula

Вли ние диэфира на нробивное напр жение трансформаторного масла (ГОСТ 982-56) оценивают на стандартном разр днике АИИ-70. Определ ют пробивное напр жение 0,5; 1,0; 3,0; 5,0 и 7%-ных растворов диэфира в трансформаторном масле. Результаты испытаний приведены в табл. 1.The effect of the diester on the intrusive voltage of the transformer oil (GOST 982-56) is evaluated on a standard discharge of AII-70. Breakdown voltage 0.5; 1.0; 3.0; 5.0 and 7% solutions of diester in transformer oil. The test results are shown in Table. one.

Таблица 1 Как ВИДНО из приведенных данных, введе- 25 ние минимального количества (0,5%) диэфира в трансформаторное масло резко (более чем в 1,5 раза) повышает величину пробивного напр жени  (Епр). Дл  концентраций 3-5% величина Е „р увеличиваетс  до 55-57 кв., т. е. зо в 2,5 раза по сравнению с исходным маслом. В дальнейшем пробивное напр жение повышаетс  незначительно. Таким образом, оптимальна  концентраци  диэфира 3-5%. Диэфир ортокремниевой кислоты оказыG6H5gt (OC9lii9).20i(H.2)20(Cli2)20Si(OC9Hj9}2C6Hj Table 1 As SPECIFIC from the above data, the introduction of a minimum amount (0.5%) of diester into transformer oil dramatically (more than 1.5 times) increases the value of the breakdown voltage (Епр). For concentrations of 3-5%, the value of E p is increased to 55-57 sq. M., I.e., by 2.5 times compared with the original oil. In the future, the breakdown voltage rises slightly. Thus, the optimum concentration of the diester is 3-5%. The orthosilicic acid diester is provided by G6H5gt (OC9lii9) .20i (H.2) 20 (Cli2) 20Si (OC9Hj9} 2C6Hj

вает многофункциональное положительное действие на основные эксплуатационные показатели изол ционного масла.It has a multifunctional positive effect on the main performance indicators of insulating oil.

Стабильность изол ционного масла против окислени  при 160° С в течение 50 час в присутствии медной пластинки и антипенные свойства по методу ГАЗ приведены в табл. 2.The stability of the insulating oil against oxidation at 160 ° C for 50 hours in the presence of a copper plate and the anti-foam properties according to the GAS method are listed in Table. 2

Таблица 2 в количестве 3-5 вес. %. Приведенные данные показывают, что по окислительной стабильности и антипенным свойствам предлагаемое изол ционное масло превосходит известное. Предмет изобретени  Изол ционное масло на основе минерального масла с добавлением присадки, отличающеес  тем, что, с целью повышени  термоокислительной стабильности, в его состав в качестве присадки введен диэфир ортокремниевой кислоты формулыTable 2 in the amount of 3-5 weight. % These data show that, according to the oxidative stability and anti-foam properties, the proposed insulating oil surpasses the known one. The subject of the invention is an insulating oil based on mineral oil with the addition of an additive, characterized in that, in order to increase thermo-oxidative stability, an orthosilicic acid diester of the formula
