Do you know, whether it is a towering tower or equipment-intensive substation, insulators are known as the guardian of electric power safety of the invisible line of defense. They may seem ordinary, but shoulder support wires, isolate the current, to ensure the stability of power transmission of the key mission, its purpose is to ensure that the current flows along the established path, to prevent it from leaking to the earth or other unintended direction. However, this line of defense is also facing the threat of dirt.
And the main threat to insulators - filth - comes from a wide range of sources and is complex. Natural factors are one of the important sources of filth. In dusty areas, a large number of sand, dust particles in the air will be attached to the insulator surface; coastal areas, salt substances will gradually accumulate on the surface of the insulator; pollen, animal feces will also become an integral part of the dirt. These naturally occurring filth accumulates over time, constantly eroding the insulating properties of insulators.
Pollution generated by human activities exacerbates the problem of insulator fouling. Industrial production processes such as sulfur dioxide, nitrogen oxides with the diffusion of air, precipitation to the surface of the insulator, the formation of difficult to remove the chemical deposits; in addition, agricultural production of straw burning soot, the same will be on the surrounding insulators caused by pollution.
In the event that insulators are not cleaned/replaced in time, the insulation resistance will drop. At this time, insulators that can originally withstand high voltages may also experience strong localized arcing under normal operating voltages, which may eventually lead to insulator flashover along the surface, or even trigger equipment damage, line tripping, and result in a large-scale power outage.
Because of this, real-time monitoring of insulator fouling status is particularly important. Shenzhen Dingxin Intelligent Technology Co.'s high-voltage transmission line Online Insulator Filthiness Monitoring System Model No. DX-WPS100-WH, by means of advanced monitoring techniques The DX-WPS100-WH, through advanced monitoring technology and equipment, such as temperature monitoring, humidity monitoring, equivalent salt density monitoring, ash density monitoring, back to the monitoring center for analysis and diagnosis, to help electric power personnel timely and accurately grasp the degree of dirt on the surface of the insulator and insulating properties of the change. Once the potential risk of flashover is detected, operation and maintenance personnel can quickly take measures, such as cleaning insulators, applying anti-fouling flash coatings, or replacing aging and heavily soiled insulators, to nip accidents in the bud, and quickly avoid power interruptions and equipment damage due to insulator flashover.
