Abstract

The invention discloses an apparatus for measuring an operating parameter of an electronic device. The apparatus comprises a shell, and a current measurement module, a temperature measurement module and a calculation control module accommodated in the shell, wherein the temperature measurement module is used for measuring the absolute temperature and the environment temperature of the electronic device and sending the measured values of the absolute temperature and the environment temperature to the calculation control module; the current measurement module is used for measuring the current ofthe electronic device and sending the value of the measured current to the calculation control module; the electronic device has an absolute temperature threshold; the electronic device has a temperature rise threshold corresponding to the measured current; the calculation control module judges whether the absolute temperature value exceeds an absolute temperature threshold value or not; the calculation control module calculates the actual temperature rise of the electronic device based on the absolute temperature and the environment temperature; and the calculation control module determineswhether the actual temperature rise exceeds a temperature rise threshold. A measurement method for measuring an operating parameter of an electronic device is provided.

Description

technical field [0001] The present disclosure relates to an apparatus for measuring operating parameters of an electronic device and a measuring method thereof, and also relates to an apparatus for measuring operating parameters of a multi-pole circuit breaker and a measuring method thereof. Background technique [0002] In the prior art, electronic devices generally only have a single function of temperature value over-limit alarm, that is, only measure the temperature value, and then compare it with the set value. For example, if the set value is 140 degrees, then it will alarm when it reaches 140 degrees. . [0003] However, from the principle of heating of electronic devices, the temperature rise is closely related to the magnitude of the current. Even if a fault has occurred (such as an increase in the conductor contact resistance due to untightened screws), the temperature will not rise to the previously mentioned temperature alarm set value, such as the above-mention...
