Cable heating is a common phenomenon in power operation. As the running time of power cables increases, the risk of cable heating also increases. Cable fire faults also account for a large part of overall electrical accidents, posing a great threat to safe power transmission. As cables themselves, regardless of the cause of a fire accident, they must go through the following processes: insulation damage in a certain part of the cable → intermittent or continuous discharge → significant decrease in cable insulation and local heating → explosion or arc in a certain part of the cable, and the generation of harmful gases → the entire cable tray catches fire. Due to the strong sporadic nature of cable safety issues and significant disaster losses, fire alarms and fire suppression systems are triggered after the deterioration of faults, and significant losses are often inevitable. ان کان علاوه, the cost of fire suppression systems themselves is high, and their effectiveness in terms of functionality and economy still needs to be verified. The power management department has always prioritized preventive maintenance, especially encouraging the development of automated equipment that can monitor in real-time on a large scale. The number of wind turbines in wind farms is huge, with a variety of models. The cables are distributed in each wind turbine and run through the entire tower from the engine compartment. The internal cable inspection of the wind turbine belongs to high-altitude operation, requiring climbing at least 70 meters high tower each time. The working surface is narrow, which poses a certain degree of danger compared to the ground, and the work intensity is extremely high.
The high-voltage switchgear of a substation is an important electrical equipment. As a widely used guiding device in the power system, the 35kV high-voltage switchgear can generate heat due to oxidation, dust, looseness, overload, poor contact, and other reasons during long-term operation of the equipment. The heating parts are prone to safety hazards. The contacts and busbar connections in the switchgear generate heat due to aging or excessive contact resistance, and the temperature of these heating parts cannot be monitored, ultimately leading to fire accidents. The tightness of the connection between the high-voltage equipment knife switch and other parts, the oxidation and corrosion of the switch surface, and the looseness of the fastening bolts cannot be detected during operation. These are all causes of overheating and even serious accidents in high-voltage equipment. How to avoid accidents through online temperature monitoring has become the main problem at present. By monitoring the operation of the contact temperature inside the switchgear, it is possible to effectively prevent the occurrence of a fire in the switchgear
1. Real time monitoring of the temperature of the contacts and hotspots inside the switchgear;
2. Multi channel temperature monitoring, can meet customer needs;
3. Stable temperature measurement, اعلي voltage مزاحمت, مخالف مداخلت, موصليت, ڊگهي خدمت زندگي, passive;
4. The contact measurement method requires a probe diameter of less than 3mm to meet insulation requirements.
