Stress superposition test platform applied to meter

The invention provides a stress superposition test platform applied to a meter. The test platform comprises a temperature-variable experiment box (3) which is provided with a first outlet side (301), a second outlet side (302) and an inlet side (303). The test platform experiment device (1) further comprises a stress module group and a bidirectional power supply change-over switch (5). The output end of the bidirectional power supply change-over switch (5) is connected with the inlet side (303). Each stress module in the stress module group is connected with an input end of the bidirectional power supply change-over switch (5). A voltage drop device (6) is connected with the other input end of the bidirectional power supply change-over switch (5). The test platform provided by the invention has the advantages that the test platform can superimpose various interference factors to simulate the most real on-site environment to test the meter, and whether the meter is in a normal working state under the superpose
