Abstract

The invention discloses an identification method of a partial discharge fault of electrical equipment, an apparatus and a system thereof. The method comprises the following steps of acquiring a discharge signal of the electrical equipment; inputting the discharge signal of the electrical equipment into a parallel identification model and acquiring a plurality of parallel identification results, wherein the parallel identification model is deployed on a plurality of sub-nodes; and gathering the plurality of parallel identification results and acquiring a fault identification result. In the prior art, an identification scheme of the partial discharge fault of the electrical equipment is single machine identification so that partial discharge fault identification of a lot of data can not be satisfied. By using the method, the apparatus and the system of the invention, the above technical problem is solved.

Description

technical field [0001] The invention relates to the field of partial discharge fault identification of high-voltage electric equipment, in particular, to a method, device and system for identifying partial discharge faults of electric power equipment. Background technique [0002] Partial discharge is a non-penetrating discharge phenomenon caused by local defects in the insulating medium. Local defects (such as bubbles, cracks, suspended metal particles and electrode burrs, etc.) Partial discharge faults occur under certain operating conditions. Partial discharge is an important symptom of insulation cracking in the long-term operation of power equipment such as transformers, GIS, and cables. If the partial discharge fault of the equipment has not been found and dealt with, it may eventually lead to catastrophic failure of the power equipment. Partial discharge detection can effectively reflect the insulation fault inside the transformer, and can distinguish the discharge ...
