Abstract

The invention discloses a visual allochroic insulator coating and a preparation method thereof. The visual allochroic insulator coating is prepared from the following raw materials in parts by weight: 40-50 parts of silicon rubber, 4-7 parts of phthalocyanine blue, 1-6 parts of calcium carbonate, 0.1-1.0 part of lead carbonate, 1-3 parts of talcum powder, 15-20 parts of cadmium red, 10-15 parts of greenish orchid, 1-3 parts of titanium dioxide, 1-5 parts of barium metaborate, 1-3 parts of dispersing assistant and 1-3 parts of binder. By using a visual rubber insulator containing the visual allochroic insulator coating disclosed by the invention, the flashover position can be obviously seen under the condition of not climbing on the rod, and the flashover origin can be judged.

Description

technical field [0001] The invention relates to a raw material composition of an insulator paint, in particular to a raw material composition of a visible color-changing insulator paint and a visible rubber insulator including the paint. Background technique [0002] Insulators (disk insulator strings or composite insulators) of high-voltage transmission lines often flashover during operation due to surface pollution, lightning strikes on the line, or operating overvoltage on the line. The flashover of the insulator leads to short-circuit grounding, which will not only burn out the insulator, but also cause the circuit breaker in the substation to trip, causing short-term or long-term power outages on the line, resulting in heavy losses. As shown in Table 1, insulator flashover accounts for more than 85% of insulator failures. [0003] Table 1. The approximate failure ratio of composite insulators in my country due to different causes [0004] cause of issue ...
