Problems solved by technology

The shortcoming of the existing internal temperature detection of the power distribution cabinet is that the near-infrared laser is required to continuously excite the temperature-sensitive probe, that is, continuous power supply is required. When there is a sudden power failure, the temperature-sensitive probe will Failed, no longer continuous temperature monitoring

Embodiment

[0030] Preparation of thermosensitive probes

[0031] Add 1 mmol of yttrium chloride, 10 milliliters of oleic acid, and 15 milliliters of octadecene into a 50 milliliter three-necked bottle at room temperature, and raise the temperature to 160 o C, and kept warm for 50 minutes; after the reaction was completed and cooled to room temperature, 3 mmol of ammonium fluoride was added, and then the temperature was rapidly raised to 310 °C under nitrogen protection conditions. oC , and incubated for 90 minutes; after the solution was cooled to room temperature, ethanol was added to centrifuge to obtain a precipitate, and the product was washed with a mixture of ethanol:cyclohexane at a ratio of 3:1, and then at 60 oC YF is obtained after drying 3 Product; With 0.9 millimoles of lutetium chloride, 0.1 millimoles of erbium chloride, 0.05 millimoles of lithium acetate, 10 milliliters of oleic acid, 15 milliliters of octadecenes, join in the 50 milliliters of three-necked flasks at room...

Abstract

The invention relates to the field of safety monitoring of power distribution cabinets, in particular to a power distribution cabinet for real-time temperature monitoring without continuous power supply. A power distribution cabinet for real-time temperature monitoring without continuous power supply is characterized in that an X-ray light tube and a temperature-sensitive probe are arranged in the power distribution cabinet, the X-ray light tube excites the temperature-sensitive probe, and the temperature-sensitive probe has Er3+ ion doped fluoride with long afterglow performance. The method can still be well applied to on-line temperature monitoring of the power distribution cabinet under the condition of sudden power failure.

Description

technical field [0001] The invention relates to the field of safety monitoring of power distribution cabinets, in particular to power distribution cabinets for real-time temperature monitoring without continuous power supply. Background technique [0002] The power distribution cabinet is often used in the environment of high voltage, high current and strong magnetic field. Therefore, the internal wiring will cause local temperature rise due to surface oxidation, corrosion or aging. In the case of continuous heat accumulation, there are potential safety hazards . Since the local temperature is an important variable parameter, online monitoring of the temperature inside the power distribution cabinet can effectively avoid fire accidents caused by high temperature and ensure the safe operation of the power system. [0003] At present, the automatic detection method of the internal temperature of the power distribution cabinet is mainly the fluorescence temperature measurement...
