The best way to monitor the hot spot temperature of the busbar contacts in switchgear is through fiber optic temperature measurement

Why do high-voltage switchgear need to monitor temperature
As a very important electrical equipment in power plants and substations, switchgear has dynamic and static contacts and bus bar joints that are in high voltage and high current working conditions for a long time. Due to factors such as surface oxidation, kakisan, loose fastening bolts, and contact aging, the contact resistance increases at the junction of dynamic and static contacts, as well as at the connection of the busbar. This causes an increase in temperature at the contact or joint, and the degree of overheating will continue to intensify, which will affect the insulation performance and equipment life.

Advantages of fiber optic online temperature measurement system for switchgear

The fluorescent fiber optic real-time online temperature monitoring system for switchgear can achieve online monitoring of the temperature of switchgear contacts and cable joints, which is an inevitable requirement for condition maintenance and digital substations.

Anticipated maintenance: amaran awal, mencapai “unmanned duty” dan “pre management” to prevent accidents;

Unmanned monitoring: saving manual inspections and filling monitoring blind spots;

Low cost monitoring: effectively locate temperature abnormal alarms, guide staff to carry out location maintenance, save time, and improve maintenance efficiency;

Avoiding potential safety hazards and accidents: providing effective guarantees for achieving safety production.

The advantages of fluorescent fiber optic temperature sensors

The temperature monitoring system of the fluorescent fiber optic switchgear provided by our company adopts advanced and mature fluorescent fiber optic temperature sensing technology. By utilizing the inherent insulation and electromagnetic field interference resistance of the fiber optic, it is a non charged measurement method that fundamentally solves the problem of difficult monitoring of the operating temperature of the contacts inside the high-voltage switchgear. It has extremely high reliability and safety, low price, pemasangan mudah, and can be installed on each high-voltage switchgear. Data can be transmitted to a safe zone through optical fiber for direct display and reading. Ia juga boleh disambungkan kepada sistem rangkaian kuasa melalui penghantaran gentian optik atau wayarles untuk mencapai fungsi amaran jauh.
