Problems solved by technology

[0003] Existing anti-pollution flashover methods mainly apply RTV anti-pollution flashover paint on the outer insulating surface of electric porcelain or glass, supplemented by regular manual cleaning of pollution, and use of silicone rubber composite external insulation, etc. In the case of pollution deposition, it will reduce the pollution flashover voltage level of the composite external insulation, which affects the normal operation of the power system, and the operation performance of the composite external insulation is difficult to be repaired in time. Therefore, the present invention proposes a transmission and transformation Quick Recovery Method for Operational Performance of Composite External Insulation of Electrical Equipment

Embodiment 1

[0027] see figure 1 The invention provides a method for quickly recovering the operation performance of composite external insulation of power transmission and transformation equipment, which includes the following steps:

[0028] S1. Acquisition of air environment information. After sampling the polluted particles in the air during smog and rainy and snowy weather and sampling the rainy snow, the rainy snow is heated. When heated to 12 degrees Celsius, it passes through a 375-mesh filter. The net filters the solid particles and analyzes the composition of the solid particles. Under the conditions of smog, rain and snow in S1, the change of atmospheric composition will definitely change the pollution on the outer insulation surface of the power transmission and transformation equipment, affecting the power transmission and transformation. The degree of pollution on the outer insulating surface of electrical equipment, for the collection and filtration of haze and rain and snow...

[0042] see figure 1 The invention provides a method for quickly recovering the operation performance of composite external insulation of power transmission and transformation equipment, which includes the following steps:

[0043] S1. Acquisition of air environment information. After sampling the polluted particles in the air during smog and rainy and snowy weather and sampling the rainy snow, the rainy snow is heated. When heated to 18 degrees Celsius, it passes through a 400-mesh filter. The net filters the solid particles and analyzes the composition of the solid particles. Under the conditions of smog, rain and snow in S1, the change of atmospheric composition will definitely change the pollution on the outer insulation surface of the power transmission and transformation equipment, affecting the power transmission and transformation. The degree of pollution on the outer insulating surface of electrical equipment, for the collection and filtration of haze and rain and snow...

Abstract

The invention discloses a method for quickly recovering the operating performance of the composite external insulation of power transmission and transformation equipment, comprising the following steps: S1, air environment information collection, by sampling the pollution particles in the air during fog and haze and rainy and snowy weather, and collecting rain and snow After sampling, the rain and snow are heated, and when heated to 10-20 degrees Celsius, the solid particles are filtered through a 350-400 mesh filter screen, and the composition of the solid particles is analyzed; S2, the area of ​​the external insulating surface Sampling of pollution, collecting 10-20 square centimeters of pollution on the outer insulation surface, and measuring the quality and thickness, the present invention analyzes the degree of pollution of the outer insulation in haze, rain and snow weather and non-haze, rain and snow weather In contrast, when foggy days and rainy and snowy days come, preparatory measures can be taken in advance to prevent pollution flashover in power transmission and transformation systems, and solve the problem that the operational performance of composite external insulation is difficult to be repaired in time.

Description

technical field [0001] The invention belongs to the field of power transmission and transformation, and in particular relates to a method for quickly recovering the operation performance of composite external insulation of power transmission and transformation equipment. Background technique [0002] The transmission of current often leads to loss due to the heat of the line, so the voltage is increased through transformers during transmission, so that the current becomes smaller to reduce heat loss. High-voltage electricity is very dangerous, and the target electrical appliances do not need such a high voltage, which requires the voltage to be reduced through power transformation. Since multiple power transformations are required in the process of current transmission, the transmission of current is called transmission. Substation, pollution flashover refers to the dirt attached to the insulating surface of electrical equipment under humid conditions, its soluble substances...
