Abstract

Изобретение может быть использовано для контроля напряжения пробоя электроизоляционных жидкостей. По первому варианту в способе напряжение подают попеременно на несколько пар электродов, а в устройстве источник напряжения соединен с каждой парой электродов через коммутатор. По второму варианту в способе напряжение подают одновременно на несколько пар электродов, при этом все пары электродов кроме одной изолируют, а устройство содержит изоляционную пластину с возможностью установки её во все кроме одной пары электродов попеременно. По третьему варианту в способе напряжение подают одновременно на несколько первых неподвижных электродов и подвижную электропроводную площадку, образующую в каждом цикле испытаний пару с одним из первых электродов, а устройство содержит вращающийся цилиндр и неподвижные электроды, равномерно размещенные на боковой стенке испытательной ячейки, один из которых в каждом цикле испытаний образует пару с электропроводной площадкой на вращающемся цилиндре. Электроды могут иметь различную форму. Технический результат - снижение трудоемкости и повышение точности при испытаниях.The invention can be used to control the breakdown voltage of electrical insulating liquids. In the first embodiment, in the method, the voltage is supplied alternately to several pairs of electrodes, and in the device, a voltage source is connected to each pair of electrodes through a switch. According to the second variant in the method, the voltage is applied simultaneously to several pairs of electrodes, while all pairs of electrodes except one are isolated, and the device contains an insulating plate with the possibility of installing it in all but one pair of electrodes alternately. In the third variant, in the method, voltage is applied simultaneously to several first stationary electrodes and a movable electrically conductive platform, which in each test cycle forms a pair with one of the first electrodes, and the device contains a rotating cylinder and stationary electrodes uniformly placed on the side wall of the test cell, one of which in each test cycle forms a pair with an electrically conductive platform on a rotating cylinder. Electrodes can have a different shape. The technical result - reducing the complexity and improving the accuracy of the tests.
