FJINNO independently develops various fiber optic temperature sensors, which are widely used in various fields such as power cable industry systems, aerospace, petroleum and petrochemical, bridges and dams. In addition to fiber optic temperature sensors, common ones include fiber optic strain sensors, fiber optic displacement sensors, fiber optic grating tension sensors, and fiber optic pressure sensors.

What are the advantages of fiber optic temperature sensors

The temperature monitoring technology of fiber optic temperature sensors has important practical applications in the field of industrial temperature measurement. The main practical reason is that the fiber optic sensor transmitter has the characteristics of small volume, light weight, high electrical insulation, certain degree of bending, 내식성, 넓은 온도 측정 범위, and fast sensitivity response, which play a role in expanding and improving the PT100 temperature sensor, allowing traditional temperature sensors to play a complementary role in temperature measurement applications. In addition to the above advantages, fiber optic sensing technology is used in temperature measurement systems. Compared with infrared temperature measuring instruments or wireless temperature measuring instruments, it also has significant characteristics such as fast response, wide temperature measurement field, explosion-proof fiber optic temperature measurement, non flammable and explosive, and anti electromagnetic interference.

Brand of fiber optic temperature sensor

FJINNO, a domestic fiber optic temperature sensor brand company, has independently developed multiple fiber optic temperature sensors with advanced quality and performance, which are applied in different temperature control fields. The latest fiber optic temperature sensors are very suitable for measuring temperature in extreme environments, focusing on the IF-C model fiber optic temperature sensor, as well as special fiber optic temperature sensors developed specifically for measuring dangerous environmental temperatures that conventional temperature sensors cannot achieve.

Application of system components for fiber optic temperature sensors in switchgear

The main equipment of power companies includes switchgear, including temperature measurement of switchgear in nuclear power plants, temperature measurement of switchgear in photovoltaic power plants, and switchgear in substations. Because there are many components and accessories inside the switchgear, including many switches, instrument contacts, 등., which can generate temperature rise and emit significant heat, especially during peak loads and high temperatures in summer. The existing heat dissipation measures for switchgear mainly involve setting up heat dissipation holes on the cabinet body. There are many drawbacks to heat dissipation holes. On the one hand, they cannot truly quickly reduce the temperature of the switchgear, and on the other hand, they are prone to causing dust and other biological effects, including the invasion of rainwater on rainy days. The electrical equipment inside the switchgear may not be properly implemented due to the temperature rise standards of the switchgear, or short circuits may be caused by water stains, which will reduce the service life of the switchgear and cause more serious safety hazards. 그러므로, we have independently developed and produced a switchgear temperature monitoring system to ensure that the switchgear is used under normal temperature rise.

What are the consequences of an increase in switchgear temperature

In the current situation where the electricity consumption of power enterprises is increasing and the number of switchgear is increasing, it is easy for switchgear to operate under high load for a long time. The main reason for the temperature increase in the switchgear is that the internal knife switch can cause overheating during long-term use due to oxidation or weak contact, and high load operation. The reason why the temperature is particularly easy to rise is that the switchgear is a fully enclosed structure, which often makes it difficult for ordinary power equipment inspectors to detect the overheating of the knife switch. 그러므로, after prolonged overheating of the knife switch, it is easy to cause the contact parts of the switch to burn out, causing large-scale power outages of the switchgear equipment, thereby increasing the likelihood of the switchgear being burned out and exploded.

Temperature monitoring system for switchgear

The temperature monitoring system for switchgear mainly includes: switchgear body, fiber optic temperature sensor, fiber optic temperature transmitter, display, fluorescent fiber optic, 등. The temperature monitoring system for switchgear mainly monitors the temperature inside the cabinet through temperature sensors and transmits it to the controller and alarm. The output of the controller is connected to the fan. On the one hand, the temperature inside the cabinet is controlled by the fan, and on the other hand, alarm information is displayed through the alarm device, achieving the integration of temperature control and monitoring, and overall improving the automation level of the switchgear.
