Problems solved by technology

In the experiment, it is often necessary to change the radius of curvature of the needle electrode to simulate different electric field uniformity. In the past, the entire needle electrode needs to be replaced. Not only is the replacement and installation process inconvenient, but also it is necessary to make a variety of needle electrodes to meet the demand, resulting in more metal consumption.

Abstract

The invention discloses a pluggable electrode and an insulating oil discharge test device, the electrode comprises an electrode tube and an electrode rod, the inner wall surface of the electrode tube is provided with a limiting groove and a guide groove, one end of the guide groove is communicated with the limiting groove, and the other end of the guide groove extends to a tube opening of the electrode tube to form an L-shaped groove. An electrode tip is arranged at the end of the electrode stem, positioning beads are arranged on the side wall of the electrode stem, when the electrode is assembled, the positioning beads are inserted into the limiting grooves along the guide grooves, and then the electrode stem is rotated to enable the positioning beads to be clamped into the limiting grooves respectively. The insulating oil discharge test device comprises a test box and a pluggable electrode, and the pluggable electrode is assembled in an oil tank of the test box. When the electrode is replaced, the electrode rod can be pulled out from the electrode tube by reversely rotating the electrode rod and rotating the positioning ball into the guide groove, and then the replaced electrode rod is inserted into the electrode tube, so that the whole electrode does not need to be detached from the test box, and the replacement speed of the electrode in an insulating oil discharge test is increased; and the test efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of testing dielectric strength or breakdown voltage, in particular to a pluggable electrode and an insulating oil discharge test device. Background technique [0002] In order to simulate the long-gap discharge of insulating oil under an uneven electric field, the actual test electrodes mostly use the "needle-plate" electrode system, and need to be used in conjunction with a specific long-gap test oil tank. In the experiment, it is often necessary to change the radius of curvature of the needle electrode to simulate different electric field uniformity. In the past, the entire needle electrode needs to be replaced. Not only is the replacement and installation process inconvenient, but also it is necessary to make a variety of needle electrodes to meet the demand, resulting in more metal consumption. materials and processing time. Contents of the invention [0003] Aiming at the deficiencies in the prior ar...
