Abstract

The invention discloses a repairing material for repairing a sealing defect and a preparation method of the repairing material, and relates to the field of power system equipment maintenance. The problem that an existing leaking stoppage technology is low in reliability is solved. The invention discloses a repairing material for repairing a sealing defect. The repairing material comprises epoxy resin E44, a curing agent FS-2B, calcium carbonate, silicon carbide, fumed silica and zinc powder, every 100 parts of the repairing material comprises the following components in parts by weight: 10 parts of epoxy resin E44, 10 parts of the curing agent FS-2B, 43.5 parts of silicon carbide, 21.5 parts of calcium carbonate, 6.5 parts of fumed silica and 7.5 parts of zinc powder. According to the repairing material for repairing the sealing defect, the preparation method of the repairing material, the repairing method applying the repairing material and the repairing device of the repairing material, compared with repairing of a traditional bonding technology, a repaired leakage point can resist oil pressure, does not fall off and resists corrosion of transformer oil, and long-term use is achieved.

Description

technical field [0001] The invention relates to the field of power system equipment maintenance, in particular to a repair material for repairing sealing defects and a preparation method thereof. Background technique [0002] Oil-immersed transformers operate all the year round, and are subject to various factors such as thermal expansion and contraction, outdoor aging, etc., often causing insulating oil leakage problems, which affect the safe operation of equipment, and in severe cases lead to power outages in the power grid, and even fire accidents. Finding a plugging method for oil leakage in oil-immersed transformers is of great significance for ensuring the safe operation of the power system, improving the efficiency of power grid maintenance, and reducing the cost of power grid operation. [0003] The existing plugging methods mainly include welding plugging and bonding plugging. Practical engineering experience shows that there are deficiencies in welding plugging. ...
