Abstract: A method for controlling temperature and humidity in a storage device, in which (S1) a set temperature range and a set humidity range of the storage cavity are obtained; (S2) an initial temperature in the storage cavity is obtained, and the temperature in the storage cavity is adjusted by the temperature regulating system to reach the set temperature range; and (S3) an initial humidity in the storage cavity is obtained, and the humidity in the storage cavity is adjusted by the humidifying system and the dehumidifying system to reach the set humidity range. A system for implementing such method includes an acquisition module, a temperature adjustment module and a humidity adjustment module. A computer-readable storage medium stores a computer program, which is configured to be executed by a processor to implement the aforementioned method.

Abstract: The present disclosure provides a system and a method for measuring hot-spot temperature of a transformer, wherein the measurement system comprises a processor, an oscilloscope and a plurality of ultrasonic sensors, wherein the ultrasonic sensors are oppositely arranged on an outer wall of a transformer oil tank and electrically connected with the oscilloscope, and the oscilloscope is electrically connected with the processor; the ultrasonic sensors receive signals transmitted by the oppositely arranged ultrasonic sensors and transmit them to the oscilloscope. The method, by applying an ultrasonic wave to measure the hot-spot temperature of a transformer in real time, solves the problems that methods in the prior art are susceptible to the external environment, have short service life and cannot correctly measure the internal temperature of the transformer.
