Sampling packet for detecting salt density value of power external insulation equipment and sampling method thereof

Abstract

The invention relates to a sampling packet for detecting a salt density value of power external insulation equipment, which is characterized by mainly comprising a sampling vet tissue and a sealing bag, wherein the sampling wet tissue consists of a non-woven fabric wet tissue substrate and a mildewproof layer, soaking in the surface of the substrate, and is arranged in the sealing bag. The invention also relates to a sampling method which comprises the following steps that in the work sampling field, an operator takes out the sampling vet tissue, clamps the sampling vet tissue by utilizing a clamp arranged on a special insulation rod of a power system and carries out electrified sampling operation, or the operator uses the sampling wet tissue on the external insulation equipment to wipe dusts and filth on the surface of an insulator, thereby enabling the dusts to be adhered to the mildewproof layer which soaks in the surface of the substrate; and the operator bags the sampling wet tissue with the dusts and the filth into the sealing bag and posts or sends the sealing bag to a detection department for centralized detection. The invention has the advantage of convenient and complete sampling and can carry out multi-point sampling, remote transmission of a sample and electrified operation and realize sampling in all seasons. The efficiency of the sampling method is several tens of times higher than that of the traditional sampling method.

Description

technical field [0001] The invention belongs to the detection of electric power external insulation equipment, and in particular relates to a sampling bag and a sampling method thereof for detecting the salt density value of electric power external insulation equipment. Background technique [0002] The special detection of salt density value of external electrical insulation equipment is an important safety technical index. The basic procedure is to collect samples of the pollution on the surface of the external insulation equipment, and then conduct a conductivity test on the solution made of pollution. According to the value of the conductivity, the operation safety of the electric power to the insulation equipment is determined. For many years, the sampling method for power systems has been by brushing. This sampling method is inefficient and directly affects the safe operation of external insulation equipment. The disadvantages are: 1. Sampling personnel must cling to...

This sampling method is inefficient and directly affects the safe operation of external insulation equipment

The disadvantages are: 1. Sampling personnel must cling to the external insulation equipment, free up two hands, one hand supports the water tray, and the other hand dips a brush in water to scrub the dust and dirt on the surface of the external insulation equipment, and the scrubbed The dust and dirt are collected and sent to the testing department for testing. The sampling work is very inconvenient and the sampling is not thorough; 2. In order to take a more thorough sampling, some power production departments remove the insulator equipment and transport it to the laboratory. 3. The sampling time is long, and the sample transportation is inconvenient; 4. In low temperature weather, the scrubbing water is easy to freeze, and sampling cannot be done in time; 5. It is inconvenient for multi-point and long-distance sampling and sample transmission
