Embodiment Construction

[0015] The following embodiments of the present invention, together with their advantages and features, are disclosed herein, and will become apparent by referring to the following description and drawings. Moreover, it should be understood that the features of the various embodiments described herein are not mutually exclusive, and can exist in various combinations and transformation processes.

[0016] Attached figure 1 It is a top view of the prior art of the present invention. The sensor in the prior art includes a light incoupling module 6, a number of quartz rods 3, and a light outcoupling module 7. The quartz rods 3 form a ring shape and are fixed on an insulator. By comparing the changes in the intensity of the incident light and the emitted light, it can be obtained An indication of the contamination of the insulator. But the discharge in the insulator is from the center of the shed to the edge of the shed, such as figure 1 As shown in the direction 2. Therefore, the p...

Abstract

The invention relates to insulator monitoring in the field of high-voltage transmission and distribution and provides a pollution sensing device for an insulator. The insulator is in the shape of an umbrella skirt. The pollution sensing device comprises an analog insulator which has the same shape as that of the insulator, a power supply, a quartz sensor, a wireless network and a terminal computer, wherein the power supply is used for supplying current to the quartz sensor, the quartz sensor and the terminal computer are in signal connection through the wireless network, the quartz sensor comprises at least one quartz rod, the quartz rod extends to pass through the middle point of the umbrella skirt from one point of the peripheral line of the umbrella skirt of the analog insulator and extends to another point of the peripheral line of the umbrella skirt of the analog insulator, and the projection of the quartz rod to the bottom face of the analog insulator is a straight line.

Description

Technical field [0001] The invention relates to a sensor on a transmission line, in particular to a pollution sensing device for insulators of a transmission line. Background technique [0002] The surface of the insulator of power transmission and transformation equipment is easily affected by environmental pollutants in the installation area, so that the pollutants accumulated on the surface of the insulator will cause insulation breakdown flashover when damp, and insulation flashover may cause accidents and affect the reliability of the operation of power transmission and transformation equipment In the assessment of the pollution status of power transmission and transformation equipment, salt density is one of the quantitative parameters. In order to ensure safe and reliable power supply, the power department must clean the insulator string according to a predetermined cycle, and the interval of the cleaning cycle depends on the salt density value of the pollutants on the ins...
