Reactor Fiber Bragg Grating Temperature Measurement Device

Abstract

The invention relates to the technical field of a reactor temperature measuring device in a power system, in particular to a reactor fiber grating temperature measuring device. It is characterized in that it includes a left connection fixture and a right connection fixture installed on the reactor star frame, the left connection fixture and the right connection fixture are connected with the lower cover and the fixing plate through the first fastener, and the rear side plate is vertically inserted into the left connection fixture and the slots of the right connecting fixture, the clamping plate is horizontally inserted into the slots of the left connecting fixture and the right connecting fixture, the supporting piece is connected with the rear side plate through aluminum rivets, and the detector bracket and the fixing plate are connected through the first fastener connection, the fiber grating temperature detector is connected to the detector bracket through the second fastener. It can realize remote real-time monitoring through the fiber grating temperature sensing fire signal processor, and can realize high temperature pre-warning and alarm, and output related signals to realize related control. The height-adjustable installation method of mechanical contact temperature measuring point is adopted, which is convenient for installation and good maintainability.

Description

technical field [0001] The invention relates to the technical field of a reactor temperature measuring device in a power system, in particular to a reactor fiber grating temperature measuring device. Background technique [0002] Reactor, also called inductor, is used in the power system to limit the current impact caused by the sudden change of grid voltage and operating overvoltage, smooth the power supply voltage, and improve the power factor. It can prevent the interference from the grid and reduce the impact of harmonic current on the grid. Pollution, improve circuit power quality. Therefore, it is widely used in the field of power system. Under the action of high temperature, electric field and magnetic field for a long time, the insulating material in the reactor will gradually lose its original mechanical and insulating properties, such as becoming brittle, weakening of mechanical strength, and electrical breakdown. For the stable operation of the reactor and prolo...

Problems solved by technology

When the detector is damaged, it cannot be maintained

For the determination of the temperature measurement point, the current manufacturer installs the detector on the star frame or in the air gap between the envelope and the envelope. Such an installation position cannot truly reflect the actual temperature of the envelope.
