specific Embodiment approach

[0068]As a specific embodiment of an embodiment of the present invention, referring to a view, step S200 specifically includes the following steps:

[0069]S210, connect the petri dish 101 to the high frequency power supply;

[0070]S220, injecting the culture solution 105 to the culture dish 101;

[0071]S230, the sample 3 was placed in the petri dish 101 for water branches.

[0072]One end of the high frequency power supply is connected to the high voltage electrode 103, and the other end is connected to the ground electrode 104, and the high voltage electrode 103 extends from the upper portion into the culture dish 101, the ground electrode 104 is disposed outside the bottom of the culture dish 101, and the sample 3 is placed in the petri dish. The 101 is connected to the ground electrode 104, and the sample 3 covers the ground electrode 104, injecting the culture liquid 105 to the culture dish 101, the culture fluid 105 is in contact with the high voltage electrode 103, but the culture solu...

Abstract

The invention provides a cable water tree branch cultivation method and device, and belongs to the technical field of cable water tree branches. The method specifically comprises the following steps: S100, extracting an insulating layer of a cable, and increasing the surface roughness of the insulating layer so as to form a sample; and S200, carrying out water tree branch cultivation on the sample. According to the cable water tree branch cultivation method, the problems that in the prior art, a water tree branch cultivation method is greatly different from actual water tree branch growth, and water tree branch research is affected are solved.

Description

Technical field[0001]The present invention belongs to the technical field of cable water tree branches, and more particularly, it is related to a method and apparatus for cultivation of a cable water branches.Background technique[0002]The water tree branch is a cable crosslinked with steam or silane, and there is condensed water in the insulation, or in an intrusion of the insulating layer due to the outer outer sheath or the wires around the outer sheath or conductor, the branch is caused by the electric field and the temperature. The aging is broken. The aging of water branches is the main cause of the insulation breakdown of the electric cable in the wet environment, and the water tree branches may cause electric branches in a certain situation, causing insulation to break through. The growth of water branches in the cable can easily lead to different degrees of insulation levels of the cable insulating layer, and the insulating layer of the cable is the aging of the cable, which...
