Portable temperature controller calibration system based on oil tank

Abstract

The invention discloses a portable temperature controller calibration system based on an oil tank. The system is convenient to carry and move on the whole, is more convenient for field calibration, and is used for collecting an indication value of a pointer type meter of a main transformer temperature controller through a camera assembly in the field calibration without manual repeated climbing for checking. The system comprises a box body assembly, wherein the box body assembly comprises a lower box body and an upper cover for closing and opening the lower box body; a partition plate is set in the lower box body, a camera assembly positioning groove is formed in the left side of the partition plate, and a temperature control calibration host positioning groove is formed in the right sideof the partition plate; groove body buffer cotton is loaded in the groove walls of the camera assembly positioning groove and the temperature control calibration host positioning groove; a temperaturecontrol verification host is placed in the temperature control verification host positioning groove; a camera assembly is placed in the camera assembly positioning groove; a temperature control verification host comprises a box and a display screen back frame installed on the box through a damping hinge, and a control display screen used for controlling a verification assembly in the box is fixedto the display screen back frame through a butterfly nut at the top.

Description

technical field [0001] The invention relates to a calibration device for a main transformer temperature controller, which is specifically used for on-site calibration of the main transformer temperature controller. Background technique [0002] Among the various equipment in the power system, the power transformer is one of the main equipment. Whether the oil temperature and oil level of the oil-immersed transformer is normal is one of the key parameters related to the normal operation of the transformer. The oil level temperature controller for the transformer ( Also called the main transformer temperature controller) is the key equipment to ensure this parameter. The necessity of rapid calibration of oil level thermostats for transformers is particularly prominent. [0003] The main transformer thermostat calibrator on the market (existing technology) is used for regular calibration of the main transformer thermostat. The specific calibration principle is to simulate the ...

Problems solved by technology

[0004] When the on-site pointer meter of the transformer main transformer temperature controller is calibrated on site, it is necessary for the calibrator to leave the calibrator host continuously and climb up to check the temperature control of the main transformer. The display value of the on-site pointer meter of the instrument, the workload of this process is heavy, resulting in low efficiency of single-person calibration, which greatly affects the experience of the automatic design effect of the instrument itself; therefore, we try to make improvements to avoid errors in the calibration process Repeatedly check the indicated value of the pointer gauge at a high place, and design a complete thermostat calibration system that is convenient for on-site testing
