Embodiment 1

[0049] Embodiment 1 DC resistance test such as figure 1 as shown,

[0050] 1. Turn on the wireless communication module of the teacher computer, the simulation transformer and the DC resistance tester, and connect the teacher computer, the simulation transformer and the DC resistance tester respectively through wireless signals;

[0051] 2. The teacher assigns the test tasks to the students. The students select the DC resistance tester according to the test tasks and perform wiring according to the standard. The DC resistance test needs to test the high-voltage side winding and the low-voltage side winding separately. When wiring, pay attention to the star connection and angle connection. wiring difference;

[0052] 3. The simulated transformer and the DC resistance tester communicate through the test wiring connected by the students, use the wiring detection module to check whether the wiring of the students is correct, and transmit the wiring data to the teacher's computer,...

Embodiment 2

[0060] Example 2 Power Frequency AC Withstand Voltage Test

[0061] 1. Turn on the wireless communication module of the teacher computer, the simulation transformer and the AC withstand voltage tester, and connect the teacher computer, the simulation transformer and the AC withstand voltage tester respectively through wireless signals;

[0062] 2. The teacher assigns test tasks to the students, and the students choose the AC withstand voltage tester according to the test tasks and perform wiring according to the standards. Short the test side of the tested product to the high-voltage output end of the test transformer, and the non-test side to the ground. The test transformer casing, high-voltage tail X, instrument end F, and operation box casing must be reliably grounded. The operation box should have a reasonable overcurrent protection setting. For setting, connect the output of the voltage regulating power supply of the control box to the input terminal of the transformer, ...

Embodiment 3

[0071] Embodiment 3 dielectric loss test

[0072]1. Turn on the wireless communication module of the teacher computer, the simulation transformer and the dielectric loss tester, and connect the teacher computer, the simulation transformer and the dielectric loss tester respectively through wireless signals;

[0073] 2. The teacher assigns the test tasks to the students. The students select the dielectric loss tester according to the test tasks and perform wiring according to the standard. The dielectric loss test includes positive wiring and reverse wiring. The students should choose the wiring method according to different needs;

[0074] 3. The simulated transformer and the dielectric loss tester communicate through the test wiring connected by the students, use the wiring detection module to check whether the wiring of the students is correct, and transmit the wiring data to the teacher's computer, and display it in the form of a wiring diagram on the teacher's computer ; ...

Abstract

The invention relates to a transformer electrical test simulation teaching system, which is characterized in that a wireless communication module of a teacher's computer, an imitation transformer anda simulation test instrument is started, and the teacher's computer, the imitation transformer and the simulation test instrument are allowed to be connected correspondingly through a wireless signal;a student selects the simulation test instrument according to test tasks and carries out wiring according to the standard; whether student's wiring is correct or not is checked through a wiring testmodule, wiring data is transmitted to the teacher's computer, the wiring test module can check errors and feeds back the errors to the teacher's computer and the simulation test instrument, and then,the student cannot continue the test; and if wiring is correct, the students can start the test. The system can meet the requirements of transformer electrical test technique and skill teaching and assessment, and enable the students to carry out transformer electrical test standard operating procedure and experimental skill training and assessment in an environment close to a real scene.

Description
