Fiber optic thermometer system application on box-type substation

Photovoltaic power transmission in an indispensable piece of equipment called box-type substation, referred to as box variable; box variable in a large number of lines as well as other devices, so there will often be a line short circuit or other circumstances resulting in the box variable within the local burned or even caused by a fire, so in the box-type substation on the installation of temperature measurement devices, you can use the fluorescent fiber temperature measurement system.

Box-type substation fluorescent fiber temperature measurement system features

(1) Temperature measurement range: -20~+150℃;

(2) Temperature measurement accuracy: ±1℃;

(3) Contact measurement mode, does not affect the insulation performance of the box-type substation; fluorescent fiber optic sensor through the frequency voltage test, 20cm voltage is not less than 80kV, and provide inspection reports;

(4) The system is not affected by the electromagnetic environment in the box variable and provide relevant electromagnetic compatibility test report;

(5) can save temperature data and alarm temperature and time parameters;

(6) Probe life of not less than 30 years.

In the power system, the temperature change of power equipment is a very important indicator, which is related to the safe and stable operation of power equipment. During the operation of the substation, the electrical contact of the equipment will cause the contact resistance of the electrical contact to increase due to the manufacturing of the equipment, oxidization by electric shock, arc impact, etc., so that its temperature rises. When the temperature rises to a certain level, the mechanical strength and electrical strength of the equipment will decline, which will lead to a short circuit of the electrical equipment, or even cause damage to the equipment, seriously threatening the safe and stable operation of the power grid.

The use of FJINNO box variable fluorescent fiber optic temperature measurement device for real-time monitoring of the temperature of the electrical equipment can help the duty personnel to find problems as early as possible to eliminate hidden dangers, to ensure the safe operation of the power system.
