Abstract

The invention discloses a transformer real-time evaluation device based on noise and temperature. The transformer real-time evaluation device comprises a temperature sensor, a wireless communication device and a portable evaluation device that are connected inside a transformer. The portable evaluation device comprises a display device, a storage device, a comparator, a timer, an alarm device anda noise detector which are respectively connected onto a PLC control device of the portable evaluation device. The PLC control device obtains the maximum temperature of several cycles of the transformer during a period of time recorded in the storage device, and simultaneously obtains the noise of the noise detector in the same period of time. The real-time evaluation device of the invention has comprehensive evaluation information and complete parameters, uses a small amount of equipment, can realize the complete detection of the transformer well, can perform detection with the transformer that has not been put into use after installation or is already in use, and has a good detection effect.

Description

technical field [0001] The invention relates to the technical field of detection equipment after transformer installation, in particular to a real-time evaluation device for transformers based on noise and temperature. Background technique [0002] When transformers are applied in the field, there are a large number of adjustments to the operation of equipment process parameters, and their performance and status will gradually deteriorate over time and eventually lead to failures. Therefore, there is a need for a transformer detection and evaluation device and evaluation method, which can calculate the detection and evaluation of a single parameter and the overall detection and evaluation of the transformer, can fully reflect the operating status of the equipment, has strong practicability, good use effect, and is easy to promote and use. [0003] At present, risk assessment is used to measure the possibility and magnitude of losses caused by or to the system. It quantifies ...
