Of course, in order to achieve the object of the present invention, on the basis of this method, purposeful settings of the corresponding hardware environment are also performed, such as:
arranging a transmission line (9) in the closed box body (1) to finish the automatic transmission of the miniature circuit breaker (8); arranging a temperature adjusting device (3) in the box body (1) to provide a high-temperature and normal-temperature environment required in the production process of the miniature circuit breaker (8); and fixing the box body (1) on the ground by using a bracket.
Further, the measurement precision calibration is divided into measurement precision calibration and measurement precision verification, wherein the measurement precision calibration is completed in a normal temperature environment; the measurement precision verification, the function test and the power-on aging are completed in a high-temperature or normal-temperature environment or in a high-temperature and normal-temperature alternating environment.
Specifically, the implementation process is as follows:
a plurality of miniature circuit breakers (8) are conveyed into the box body (1) by using a transmission line (9); the miniature circuit breaker (8) is fixed by a fixing device (4); and (3) connecting the electrifying device (5) with the inlet and outlet connecting terminals of the miniature circuit breaker (8) to complete the fixing and connecting work of the miniature circuit breaker (8).

Such as: the testing that the large current is applied to all the miniature circuit breakers (8) can be realized by closing the switch elements (10) corresponding to the large current generator, and if the applied current value exceeds the set threshold value of the miniature circuit breakers (8), the miniature circuit breakers (8) can automatically trip, namely the simultaneous detection of the overcurrent protection function of all the miniature circuit breakers (8) is realized; after the operation is completed, the switching element (10) is turned off.
For another example, when the switching elements (10) corresponding to the standard voltage source and the standard current source are closed, voltage sampling precision verification and current sampling precision verification can be performed on all the miniature circuit breakers (8); after the operation is completed, the switching element (10) is turned off.
