Detection system and method for main transformer oil level temperature measurement equipment

Abstract

The invention provides a detection system and method for main transformer oil level temperature measurement equipment; and the system comprises a detection unit and a processor. The detection unit isused for detecting the working states of a main transformer oil level thermometer and a secondary loop of the main transformer oil level temperature measurement equipment, and the secondary loop is divided into a plurality of sub-loops according to the functions of the secondary loop, each sub-loop and the main transformer oil level thermometer are respectively connected to the respective corresponding detection unit; and the processor is used for receiving the working state signals of the main transformer oil level thermometer and the secondary circuit detected by the detection unit, judgingwhether the main transformer oil level thermometer and the secondary loop have faults or not and locating fault parts. Comprehensive inspection of a main transformer oil level thermometer and a secondary loop can be achieved, the efficiency and quality of acceptance, regular inspection and defect elimination work of the main transformer oil level thermometer and the secondary loop are improved, and safe and stable operation of a main transformer is guaranteed.

Description

technical field [0001] The disclosure belongs to the technical field of detection, and in particular relates to a detection system and method of a main transformer oil surface temperature measuring device. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The main transformer oil level temperature measuring equipment includes an oil level thermometer, which is a kind of temperature measuring instrument, and usually consists of a pressure instrument thermometer and a thermal resistance to realize the local indication and remote display of the measured temperature. The oil level thermometer is used to measure the oil temperature of the upper layer of the transformer oil tank, monitor whether the transformer is running normally, and prevent the transformer oil temperature from being too high and accelerate the aging of the transformer. The th...

Problems solved by technology

[0004] The inventor found in the actual operation that due to the harsh environment of the main transformer oil level thermometer and the secondary circuit, various defects often occur. Common defects include: on-site instrument panel display temperature, temperature gauge transmitter and Dispatch monitoring shows that there is a difference between the three temperatures, or a single temperature is abnormal, and the alarm signal, trip command, control air cooling and other information are sent by mistake

The work involved in the main transformer oil temperature gauge and its secondary circuit is very complicated, and the tools and methods available on site are very limited. According to the existing inspection methods, it will generate a huge workload, the work quality is not high, and the work efficiency is low. cause waste of manpower and material resources
