Charged tester for field salt density of portable insulator

Abstract

The invention relates to a charged tester for field salt density of a portable insulator. The tester consists of a test end, a main body part and a rig part, wherein the test end acquires the surface information of the measured insulator through a temperature test probe and a conductivity test probe, and wirelessly sends the acquired information to the main body part; the main body part calculates and displays the detection result; the main body part wirelessly sends a control instruction to the test end to control the working condition of the test end; and the rig part is used for installing and fixing the front of the tester on the surface of the insulator. The tester achieves charged measurement, reduces outage loss, realizes field measurement, immediately obtains the detection result, greatly shortens detection time and decreases detection cost.

Description

technical field [0001] The invention relates to the external insulation maintenance of the electric power system of the electric power engineering, in particular to a portable on-site salt dense electrification tester for insulators. Background technique [0002] During the operation of the power transmission and transformation equipment in the power system, the pollution of the external insulation of the power transmission and transformation equipment needs to be checked regularly to prevent flashover discharge of the equipment and cause power outages. The current detection method needs to clean the dirt on the equipment, test it with a special instrument in the laboratory, or use a salt dense electrification tester to conduct a power outage on-site test. The main problem of the current detection method is that the test time is long and the live test cannot be performed. , can only be measured when the equipment is powered off, but due to the requirements of equipment opera...

Problems solved by technology

The current detection method needs to clean the dirt on the equipment, test it with a special instrument in the laboratory, or use a salt dense electrification tester to conduct a power outage on-site test. The main problem of the current detection method is that the test time is long and the live test cannot be performed. , can only be measured when the equipment is powered off, but due to the requirements of equipment operation, some equipment cannot be powered off for many years, so the salt density value test cannot be performed

[0003] The live detection of the pollution status of the external insulation of power transmission and transformation equipment has become a difficult problem in this field. Although there are continuous explorations and researches, the effect is not ideal
