Switchgear cable hard and soft connector fluorescent fiber optic temperature measurement system

In the power system, the opening contact points of various types of equipment may have increased resistance due to loosening, aging, arc impact and other reasons during long-term operation. This makes the contact point temperature will continue to rise, bringing hidden dangers to the safe operation of the power grid. If not detected in time, it is easy to cause equipment explosion, fire, endangering the safety of personnel, causing large-scale power outages and other major catastrophic accidents, causing serious economic losses to the state, the collective, and individuals, and jeopardizing the safety of the national power grid. Therefore, real-time online monitoring of the temperature of key points of power equipment, timely detection and elimination of potential safety hazards is increasingly recognized and valued by the industry.

Features of the switchgear fluorescent fiber optic temperature measurement system:

1、Real-time monitoring of contact and hot spot temperature in switchgear cabinet;

2, multi-channel temperature monitoring, according to customer demand;

3, stable temperature measurement, high voltage resistance, anti-interference, insulation, long service life, passive;

4, contact measurement method, in order to meet the insulation requirements, the probe diameter is less than 3mm.

Fiber-optic online temperature measurement system is installed in the high-voltage switchgear equipment. The temperature sensor of the fiber-optic online temperature measurement system outputs signals, which are transmitted via fiber optics to the fiber-optic temperature transmitter installed on the panel of the switchgear instrumentation room, and the fiber-optic temperature transmitter summarizes and uploads the monitored temperature data to the substation integrated online monitoring system via RS485 communication bus.
