Dirt flash: an electrical phenomenon that occurs when the insulating surface of electrical equipment is covered with dirt, under humid conditions, the soluble substances in these dirt will dissolve in water, ice disaster insulating surface to form a layer of conductive film, which reduces the level of insulation, resulting in a strong discharge phenomenon on the surface of the insulator.
In particular, the insulators in the transmission lines in the long-term operation process, subject to a variety of natural environments and man-made influences, deposited on the surface of the insulators of the filth through the rain, snow, fog, frost and other meteorological conditions, and specific environments such as the line around the chemical plant for a long time to emit chemical gases, etc., will reduce the level of insulation insulators, and then may occur in the event of a filth flashover accident occurs.
Common insulator fouling:
1, insulator surface roughness, easy to accumulate dirt;
2. Insulators are exposed to the air for a long time and are susceptible to the pollution of dust and particles in the atmosphere;
3, the insulator itself the quality of the material or production process defects, so that it is easy to adsorb dirt;
4. Improper installation or maintenance can also cause dirt to accumulate on the insulator.
In order to minimize dirt deposits on insulators, Shenzhen DX Wisdom Technology's Transmission Line Insulator Filth Monitoring DeviceDX-WPS100-WH can monitor the insulator surface filth condition in real time and accurately predict the filtration failure. The device is mainly composed of data monitoring terminal and data monitoring center. The data monitoring terminal is installed near the insulators of transmission line poles (towers) or substations and is responsible for real-time monitoring; the data monitoring center is responsible for receiving, processing and analyzing the data.
1, real-time monitoring and data acquisition: The data monitoring terminal can real-time monitor the site dirt (salt density, ash density), temperature, humidity and other key parameters, and through the GSM wireless network will monitor the data back to the monitoring center.
2. Early warning and alarm: The system will send out early warning information through various ways (such as SMS, system prompts, etc.) when the data is abnormal, prompting the relevant personnel to take timely measures.
3, data storage and processing: With data storage function, the data cycle storage at least 90 days; at the same time, the system will receive the monitoring data for pre-processing, automatic identification and elimination of interference data.
4, remote control and debugging: support for remote query parameters, set parameters, data summoning, remote reset, remote timing and other functions; also through the short-range wireless debugging mode, in the field of the device of each data sensor for real-time control and debugging.
5. Self-inspection, self-diagnosis and self-recovery: With self-inspection, self-diagnosis and self-recovery functions, and can transfer the self-inspection information to the master system to ensure the stable operation of the device.
6. Hibernate and Wake Up:With hibernate function to reduce power consumption, while supporting Wake on Hibernation for monitoring when needed.
