Technical Field
The invention belongs to the field of fault early warning materials, particularly relates to a power fault early warning material and an early warning indication method thereof, and particularly relates to a power fault early warning material and an indication method thereof for fault early warning of a high-voltage overhead transmission line of a power system.
Background
In recent years, along with the continuous rise of power consumption, the obsolescence and aging speed of power equipment is accelerated, the deterioration of a working environment causes the continuous increase of load, the abnormal rise of the temperature of the equipment occurs sometimes, particularly in summer with the highest environmental temperature and the worst weather conditions, the abnormal rise of the temperature of the power equipment is frequent just in a peak period of the power load, and the abnormal rise of the temperature of the power equipment poses great threat to the safe operation of a power system and a power grid, and particularly, a high-voltage overhead transmission line exposed to the outdoor environment for a long time is easy to break down and generate danger in summer with high temperature and heat.
How to ensure the safe and stable operation of the power system and the high-voltage overhead transmission line becomes a great subject. In reality, the recovery of power supply every night after a fault causes huge social financial loss, and for severe patients in hospitals, the recovery may also mean a life cost. Especially, when a high-voltage overhead transmission line breaks down, the maintenance is difficult and slow, and the loss is increased. Because the high-voltage overhead transmission lines are generally distributed in remote and complex mountain areas and even in many remote unmanned mountain areas with steep and dangerous terrain, in order to ensure normal and safe operation and work of the power system, a large amount of manpower and material resources are consumed to inspect and maintain the lines at ordinary times, but the high-voltage overhead transmission lines with the severe terrain consume time and labor during inspection and maintenance, particularly, inspection personnel are easy to have personal danger and even pay life cost. At present, a common inspection method for a high-voltage overhead transmission line is manual inspection, and the method is time-consuming and labor-consuming, has safety problems and is low in efficiency. Although the scheme of adopting the infrared inspection of unmanned aerial vehicle is proposed at present, but infrared temperature measurement is because the influence of external factors such as measuring distance, dust and aqueous vapor, and its measuring accuracy is not high, has the shortcoming that equipment is expensive, operation requirement is higher simultaneously, so can't satisfy future smart power grids's demand. In order to monitor the high temperature of a high-voltage overhead transmission line and locate a fault position, and quickly realize early warning indication of the fault to prevent the fault, a material capable of early warning the power fault and an early warning method thereof are urgently needed to be researched. At present, many power failure indicating materials in the prior art, but these materials discolour unobviously and irreversible, cause a large amount of wastes of material, if not change indicating material in time after every power failure takes place, will not in time or can't make the instruction to power failure instruction, cause the emergence of electric power accident easily, threaten national and individual's life and property safety. Therefore, it is urgent to research a material for early warning of power failure and an early warning method thereof.

Compared with the prior art, the invention has the following beneficial effects:
1. many existing fault indication coating materials are small in adhesion and poor in oxidation resistance, and the coating is easy to fall off and oxidize after being exposed to the external environment for a long time, so that the color of the coating is changed, and the fault early warning indication effect cannot be achieved; the power failure early warning indicating material disclosed by the invention forms strong adhesive force under the interaction of the resin base material and the curing agent, is not easy to fall off in a severe external environment, can keep the color of a color-changing substance basically unchanged for a long time under the action of an antioxidant and in a normal temperature environment, can change the color only when encountering continuous high temperature, and can quickly and accurately give early warning indication to the failure of a high-voltage overhead transmission line.
2. The high-voltage overhead transmission line can bear certain high-temperature operation in a short time, and can only break down when the high-voltage overhead transmission line continuously works at high temperature for a long time, but the fault indication coating in the prior art can immediately or very short-time send out fault indication when meeting high temperature, and a maintainer can overhaul or replace the high-voltage overhead transmission line when finding out the fault indication, so that the waste of materials of the high-voltage overhead transmission line is easily caused; however, the color change of the fault early warning material has reversibility, the color change can occur when the temperature rises, the color can be recovered to the previous color after the temperature falls, the fault early warning material can be recycled, and the material is saved; the fault early warning material has obvious color change and good stability.
3. The early warning indication method can simply and quickly carry out accurate early warning on high-temperature faults, prevent the faults from occurring in time and save a large amount of manpower and material resources to a certain extent.
