[Abstract]:This paper first introduces the low-voltage switchgear, explains the development direction of the low-voltage switchgear, and states the influence of the heat problem on the low-voltage switchgear. This paper shows the importance of studying heat problem to low voltage switchgear, introduces the national standard of low voltage switchgear testing, and explains the history of test standard change. Explain the current situation of the low-voltage switchgear testing industry in our country, and the problems and contradictions in the testing process: backward detection methods, can not meet the testing needs of high-tech products. The manpower power consumption is huge. In order to solve this problem and contradiction. In this paper, we try to replace the traditional temperature rise type test method with the simulation method. Finally, the problem of the temperature rise type test of the low voltage switchgear is brought out. In view of the low voltage complete switchgear, the temperature rise type test problem of the low voltage switchgear is introduced. The temperature rise type test problem. The concept of temperature field is put forward, the finite element analysis mathematical model of temperature field of low voltage switchgear is constructed, the basic theory of heat transfer is explained, and the thermal differential equation of steady state temperature field is explained. Finally, the finite element method for temperature field analysis of low voltage switchgear is introduced. The temperature rise type test of low voltage switchgear is simulated by using ANSYS14.0 software. The three-dimensional solid model of XL-21 type low-voltage switchgear is constructed, the grid is divided, the load is applied, the data is calculated, and the simulation data is obtained. According to the requirements of the national standard, advanced electric current generating devices are used. The temperature rise type test of XL low voltage switchgear is carried out, and the temperature is monitored and collected by GP20 portable paperless recorder, and the test data are obtained. The simulation data are compared with the test data. The feasibility of simulation test method for temperature rise type test of low voltage switchgear is explained.
