Temperature rise test and measurement system and method for split heat dissipation transformer

Abstract

The invention relates to a temperature rise test and measurement system and method for a split heat dissipation transformer. The temperature rise test and measurement system includes a test power supply and a metering system, a radiator group, a plurality of groups of temperature sensors and a temperature inspecting instrument, wherein the test power supply and the metering system are connected with the split heat dissipation transformer through a circuit; the radiator group is connected with an input and output port of the transformer through a pipe; the first group of temperature sensors isdistributed at the top of the transformer, the second group of temperature sensors is distributed at the bottom of the transformer, the third group of temperature sensors is distributed around the transformer, and the fourth group of temperature sensors is distributed on the input and output port of the transformer; and the temperature inspecting instrument is connected with each group of temperature sensors through a circuit, monitors the temperature of each portion of the transformer measured by each group of temperature sensors, and records and stores measured data at intervals. The temperature rise test and measurement system is easy to operate, high in accuracy and high in practicality; and the temperature rise measurement of the split heat dissipation transformer can be implemented smoothly.

Description

technical field [0001] The invention relates to a transformer temperature rise test system and method, in particular to a temperature rise test and measurement system and method for a three-phase double-winding component heat dissipation oil-immersed power transformer. Background technique [0002] With the rapid development of my country's national economy, large cities have begun to show the characteristics of dense population, clusters of high-rise buildings, and high power load density; at the same time, land resources in urban load centers are very scarce. Therefore, building high-voltage, large-capacity substations underground has become a priority solution to meet the city's growing power load demand. Underground substations have the characteristics of more compact equipment layout, high requirements for equipment operation reliability, and high requirements for fire safety, temperature rise and noise control. [0003] During the operation of the transformer, due to ...
