Embodiment Construction

[0019] see figure 1 , figure 2 It can be seen that the present invention includes an industrial control host 1 , a data acquisition head 2 , a standard temperature bath 3 , and a temperature controller 4 to be tested. The industrial control host 1 is a dedicated development platform using an open instrument platform. The external equipment includes the data acquisition head 2, and the standard temperature tank 3 adopts the American standard temperature tank FLUKE9171. Each detection channel is composed of a data acquisition head 2, a standard temperature tank 3 and a temperature controller 4 to be detected, forming independent detection channels CH1, CH2, CH3, CH4. One end of the data acquisition head 2 is connected to the industrial control host 1 through the RS232 interface, and the other end is connected to the temperature controller 4 under test; the sensor 4-1 of the temperature controller 4 under test is inserted into the standard temperature tank 3 .

Abstract

The invention relates to an intelligent verification system of a main transformer oil temperature and winding temperature controller, relating to the technical field of verification of a temperature controller of a power supply system. The intelligent verification system comprises an industrial control main machine, data acquisition heads, standard temperature slots and tested temperature controllers; the USB interface of the industrial control main machine is expanded into at least four RS232 interfaces to be connected with at least four standard temperature slots, one end of a data acquisition head is connected with the industrial control main machine through one RS 232 interface, and the other end of the data acquisition head is connected with the tested temperature controller; a sensor of the tested temperature controller is inserted into a standard temperature slot; the industrial control main machine is internally provided with a low-power wireless data transmission module and can transmit field detection data to a background monitoring system in real time; and the intelligent verification system is provided with four independent running detection channels and can simultaneously detect four temperature controllers. Through the intelligent verification system of the main transformer oil temperature and winding temperature controller, disclosed by the invention, the intelligent verification of the temperature controller is realized, and the verification technical level and the detection efficiency of the temperature controller are improved.

Description

technical field [0001] The invention relates to the technical field of calibration of temperature controllers in power systems, in particular to an intelligent calibration system for main transformer oil temperature and winding temperature controllers. Background technique [0002] At present, some domestic temperature controller manufacturers and universities have done related research. The inventor learned from the novelty search report retrieved and issued by Sichuan Institute of Science and Technology Information that "Instrument Technology and Sensors" 2002 No. 01 magazine disclosed "A Practical Visual Recognition Instrument Automatic Verification System", a article, author Yan Yi. The system is an automatic verification system for temperature control instruments based on image processing and neural network recognition technology. Teacher Yang Changchun from East China University of Science and Technology published an article entitled "Automatic Calibration System for...
