Example Embodiment
[0026] Example one
[0027] Such as figure 1 As shown, the first embodiment of the present invention provides a fault recording method for a distribution line. figure 2 The distribution line fault recording system or the terminal equipment including the distribution line fault recording system executes the distribution line fault recording method.
[0028] The first embodiment of the present invention provides a fault recording method for a distribution line, which includes the following steps:
[0029] Step 101: According to the distribution line information and its fault type, set the corresponding current and / or voltage setting value and action setting time in the distribution line; according to the current and / or voltage value of the distribution line, set the record The waveform of the current and / or voltage in the distribution line over a period of time.
[0030] There are many types of faults in distribution lines. The common faults are overload long / short delay, short-c
Example Embodiment
[0043] Example two
[0044] Reference figure 2 , Shows the structural block diagram of the distribution line fault recording system provided in the second embodiment of the present invention, and the distribution line fault recording system in this embodiment can perform such as figure 1 The fault recording method of the distribution line shown. Specifically, the distribution line fault recording system may include the following units:
[0045] The configuration unit 201 sets the current and / or voltage setting value and the action setting time of the corresponding distribution line according to the information of the distribution line and its fault type; according to the current and / or voltage value of the distribution line, set Record the waveform of the current and / or voltage in the distribution line over a period of time;
[0046] The monitoring unit 202 monitors the current and / or voltage value in the distribution line to monitor whether the current and / or voltage value
