The technical field to which the invention belongs The invention relates to a simulation test method, especially an application Test method for parallel operation of three-phase transformers. Second, the prior art For 500MVA and 200MVA three-phase transformers, if you want to know whether the parallel function is correct, you need to do another parallel test with another unit transformer to know exactly whether the parallel function is correct. The 500MVA and 200MVA three-phase transformers are a very large and expensive set of equipment. Parallel testing with another set of transformers not only takes up a lot of space, but also invests time, labor, and equipment costs for handling, assembly, and testing. Even more expensive. For a long time, 500MVA and 200MVA three-phase transformers are operated in parallel. Because the transformer manufacturer does not have another set of transformers of the same model for testing in parallel operation after the finished product is assembled, it often happens that the transformer is transported to the construction site. When running in parallel with another set of transformers, it was only found that many wiring errors caused the transformers to fail to run in parallel. In view of the shortcomings of the traditional 500MVA and 200MVA three-phase transformers in parallel, the present inventor has started to improve the problems and make up for their shortcomings in order to find a reasonable solution. After numerous studies and analysis, Trial work, finally completed the "simulation test method for parallel operation of three-phase transformers" of the present invention. 564316 III. Summary of the Invention The main purpose of the present invention is to provide a kind of three-phase transformer parallel operation simulation financial measurement method, which includes various transformers _ tap-off ribs _ lifting and lowering control, voltage modulation control, and voltage rise and fall during stand-alone transformer operation. Function test and function test of master operation or auxiliary machine selection in parallel operation. The other purpose of this book is to provide __ three kinds of three-phase transformer parallel operation simulation test methods, which can detect the transformer tap changer switching control, voltage regulation control, voltage boost function test during single-machine transformer operation, and parallel control. Select the operation of the main machine or the function of the auxiliary machine. In order to achieve the above-mentioned object, the present invention _ a kind of three-phase transformer parallel operation simulation test method, which includes the control circuit of electric control elements such as trolleys and programmable logic controllers in order to detect mva and 20 Phase transformer parallel operation function. It is characterized in that the simulation test bench can be used as a stand-alone machine for receiving materials and transferring control, and when the parallel test is selected, the host operation or __wei can be selected, and a light emitting diode display n is provided to indicate the position of the winding tap at any time. It can also detect the out-of-step alarm yellow light indication when the tap changers of the two sets of transformers are switched asynchronously during parallel operation. The test method of the present invention is performed in the following steps:,-three-phase transformer in one control Box, the control box is then wound through a parallel test, Yuanshe pan broken r :; (: Nissei two, see Watanabe ,,, and the main four-phase transformer in parallel operation simulation test 7 (B) by the button The switch provides a controller (PLC) to simulate the output state of the transformer; a rise or fall signal is provided to the program logic winding tap for the rise or fall switch output (C). The programmable logic controller winding tap is used to connect with the transformer operating mechanism. The winding tap position indication contacts are connected in series to show the switching action of rising or falling; and, the signals of the gas phase A 1 pressure / parallel operation of the 4 phase 2 f voltage regulator are compared with each other to detect the ”No The winding tap between the two is based on the original design, lack of production # ± _, and it does have equalizing effect, so it applies for an invention patent in accordance with the law. Η, Wanshi ’s invention “Three-phase transformer in parallel "Operation simulation test method" is used to test whether the conversion between the voltages of the transformer windings is normal, whether the tap changer is raised and lowered correctly, and _, voltage rise and fall power during single operation = test, and select the master operation or auxiliary machine to follow in parallel operation Function ^, the light-emitting pole display indicates the position of the winding / knife connector at any time, and when a test is performed in parallel with the transformer, if a tap occurs • provided by a button switch-a rising or falling signal to the programmable logic control Device for lifting or winding tap switching, it can be raised from the first winding to the extreme age tap or switched from the extreme winding head, and it will do a "out of step alarm" yellow light warning when it is switched asynchronously. This simulation = 台 部 部Programmable logic controller (pLc) is used to control the operation mechanism of the tap changer of the analog transformer. Its action function is as follows: the component joint is reduced to the first winding tap. It can be used as a lifting tap switcher and it needs to be maintained at the position of the original winding tap when power is off. #The position of the winding tap is displayed by a light-emitting diode.

The analog test bench uses a programmable logic controller to control the tap changer operating mechanism of the analog transformer. Its operation function is as follows: • A push button switch provides a rising or falling signal to the programmable logic controller for lifting or winding. The joint can be switched from the first winding tap to the limit winding tap or from the limit winding 564316 component joint to the first winding tap. You can operate the lift tap changer in any position. When the power is turned off, you need to keep the position of the original winding tap. * The position of the winding tap is indicated by the light emitting diode 41.
