Embodiment Construction

[0029] Basic platforms such as figure 2 As shown, the pyramid structure is adopted, which has the advantages of strong stability, reliability and firmness, and flexible adjustment. In order to ensure the rigidity requirements, the material is made of aluminum profile, the grade is 6063 high-strength aluminum alloy. One side of the basic platform can hang and calibrate 4 temperature controllers at the same time, about 1520mm; the height is designed according to the average height of the test personnel, and is designed according to 1600mm. At the same time, when installing the temperature controller, the mechanical arm needs to be raised to avoid damage The camera, so the total height is 2000mm; the width design is determined according to the internal wiring and the diameter of the counterweight, which is 1000mm. The upper and lower parts of the basic platform adopt an open structure, which facilitates the heat dissipation of devices such as drivers, strong currents and weak c...

Abstract

The invention relates to an intelligent verification system of pressure type thermometers. The intelligent verification system comprises a mechanical part, a control part, a thermostatic oil bath and a camera, wherein the mechanical part comprises a basis platform, a mechanical arm and a transmission mechanism, and the control part comprises a main control computer, a motion-control unit, an operation unit, a data station unit and a data acquisition card. The automatic verification process of the intelligent verification system comprises automatic finding of a meter, automatic setting of the meter, reading of configuration information, automatic detection, data analysis and processing and the like. The intelligent verification system can simultaneously and intelligently verify multiple pressure type thermometers and can do a thermal modeling test to winding thermometers at the same time. In the verification process, manual intervention is not needed to increase the verification work efficiency, the manpower is saved, and the physical and psychological health of testers is not damaged.

Description

technical field [0001] The invention relates to the automatic verification of a transformer temperature measuring device in a power system, in particular to an intelligent verification system for a pressure thermometer. Background technique [0002] In the power system, the pressure thermometer is also called the temperature controller. It is not only used to measure the temperature of the transformer, but also related to the self-starting of the transformer cooler, the full stop protection of the strong oil circulation transformer cooler, and the high temperature alarm. Its operation Reliability and measurement accuracy are directly related to the safety and stability of the power system. The operational reliability and measurement accuracy of pressure thermometers are closely related to their verification work. At present, the verification of pressure thermometers generally adopts a manual verification method. The verification process is cumbersome, the workload is heavy,...
