The embodiment of the invention provides an
electron dissipation measuring device in nano modified
transformer oil. The
electron dissipation measuring device in nano modified
transformer oil comprises a sample
system, an
electron injection
system, a measurement
system and a polarization system. The sample system includes a back
electrode and an oil containing insulating ring, wherein the sample is located at the upper portion of the back
electrode and is surrounded and blocked by the oil containing insulating ring so as not to overflow, and the back
electrode is grounded; the
electron injection system includes a high-
voltage DC source and a needle point, the needle point is connected with the high-
voltage DC source, and the tip of the needle point is positioned at the upper portion the sample; the measurement system includes a
potentiometer and a collection module, wherein the
potentiometer is connected with the collection module, and the collection module comprises an
oscilloscope and a processor; and the polarization system comprises a polarization electrode and a high-
voltage DC source, wherein the polarization electrode are two flat electrodes which are respectively and symmetrically arranged on two sides of the sample, the flat electrode on one side is connected with a
direct current voltage source, the flat electrode on the other side is grounded, and a horizontal
electric field is formed in the sample. The electron dissipation measuring device provided by the invention is simple and easy to implement, and can verify whether the nano particle polarization has a capturing effect on the electron dissipation in the nano modified
transformer oil or not.
