Specifically, in this embodiment, leakage alarm reference information may be generated according to the leakage reason and the fault location, and sent to the user-associated terminal, so as to provide fault analysis information for the user.
It should be noted that, in this embodiment, the leakage alarm level may also be determined according to at least one of the leakage reason, the fault location, and the leakage current value, and then the leakage alarm level is added to the leakage alarm reference information to prompt the user of the necessity of going to the leakage location and the priority of repairing the leakage fault.

Wherein explanations of the same or corresponding terms as those of the above embodiments are omitted. Referring to fig. 2, the leakage fault analysis method provided in this embodiment includes the following steps:
s210, determining a preset working current threshold corresponding to the leakage protector based on the installation protection type of the leakage protector.
The installation protection type can be the actual protection type of the low-voltage line or the load equipment monitored by the leakage protector. Illustratively, the installation protection type may be a total protection or a secondary protection of the platform area, and the like. The preset operating current threshold may be a protection threshold of the earth leakage protector. Specifically, this embodiment can be based on the actual conditions of the low-voltage line or the load equipment that earth-leakage protector monitored, and the protection threshold value to earth-leakage protector is transferred and is optimized to the monitoring scene that adapts to earth-leakage protector, realizes on-the-spot adaptation.
In one embodiment, the determining, based on the installation protection type of the earth leakage protector, a preset operating current threshold corresponding to the earth leakage protector includes: if the installation protection type of the leakage protector is the transformer area total protection, determining that a preset working current threshold corresponding to the leakage protector is a first threshold; if the installation protection type of the leakage protector is secondary protection, determining that a preset working current threshold corresponding to the leakage protector is a second threshold; wherein the first threshold is greater than the second threshold.
For example, the leakage protector can collect current signals of a three-phase four-wire distribution network in real time, when the installation protection type is total protection of a transformer area, the preset working current threshold value can be set to be any value between 500mA and 1000mA, and the breaking time can be set to be 0.5 s; when the installation protection type is secondary protection, the preset working current threshold value can be set to 300mA, and the breaking time can be set to 0.3 s. It should be noted that, the preset operating current threshold in the above example is an empirical value, and the preset operating current threshold may be adjusted and optimized according to a field condition corresponding to the earth leakage protector in actual application. Also, the installation protection type is not limited to the above-described block total protection and secondary protection.
S220, judging whether the leakage protector detects a leakage fault or not based on the current signal collected by the leakage protector and the preset working current threshold, and if so, acquiring the leakage current value of the leakage protector.
Specifically, when the difference between the current signal and the preset working current threshold exceeds the set current difference threshold, it may be determined that the leakage protector detects a leakage fault, and the leakage current value monitored by the leakage protector is obtained.

In this optional embodiment, it is considered that the current value actually continuously floats, so that a situation that the leakage protector makes a judgment error exists, and therefore, after the leakage current value of the leakage protector is obtained and before the leakage reason and the fault position corresponding to the leakage protector are determined, secondary verification can be performed on the leakage current value, and it is ensured that the leakage protector monitors the leakage fault. The secondary verification process may be comparing the leakage current value with a preset working current threshold, and determining a verification result based on the comparison result. Through carrying out secondary verification on the leakage current value, the fault judgment error caused by current fluctuation is avoided, and further unnecessary leakage alarm reference information is avoided.
And S230, determining the leakage current value of the leakage protector and the installation environment of the leakage protector.

And S250, generating electric leakage alarm reference information based on the electric leakage reason and the fault position, and sending the electric leakage alarm reference information to a user associated terminal.
The technical scheme of this embodiment can set up earth-leakage protector's the operating current threshold value of predetermineeing according to the actual conditions of the low-voltage line or the load equipment that earth-leakage protector monitored to adaptation earth-leakage protector's monitoring scene realizes on-the-spot adaptation, has improved earth-leakage protector's leakage monitoring rate of accuracy.

s310, determining a preset working current threshold corresponding to the leakage protector based on the installation protection type of the leakage protector.
S320, judging whether the leakage protector detects a leakage fault or not based on the current signal acquired by the leakage protector and the preset working current threshold; and if so, acquiring the leakage current value of the leakage protector.
S330, acquiring a current voltage signal acquired by the leakage protector, if the difference value between the current voltage signal and the standard voltage exceeds a set protection threshold value, judging that the leakage protector detects an undervoltage fault or an overvoltage fault, and generating a protection trigger signal to be sent to the user associated terminal.
In this embodiment, the leakage protector can also detect undervoltage and overvoltage faults. Specifically, the earth leakage protector can collect current voltage information of a low-voltage line or load equipment, compare the current voltage information with a preset standard voltage, determine that an undervoltage fault or an overvoltage fault is detected if a difference value between the current voltage information and the preset standard voltage exceeds a set protection threshold value, and generate a protection trigger signal to be sent to a user associated terminal. If overload occurs to a low-voltage line or equipment monitored by the leakage protector, overvoltage faults can be generated.
Illustratively, the determining that the leakage protector detects an under-voltage fault or an overvoltage fault if the difference between the current voltage signal and the standard voltage exceeds a set protection threshold includes: if the current voltage signal is greater than the standard voltage and the difference value between the current voltage signal and the standard voltage exceeds a set protection threshold value, judging that the leakage protector detects an overvoltage fault; and if the current voltage signal is smaller than the standard voltage and the difference value between the current voltage signal and the standard voltage exceeds a set protection threshold value, judging that the leakage protector detects the undervoltage fault.
Of course, the earth leakage protector in this embodiment may also detect a phase loss or zero fault of a low-voltage line or a load device. That is, optionally, the method further comprises: if the current voltage signal has a line break or no phase voltage value, judging that the leakage protector detects a phase-lack fault or a zero-break fault; and generating a protection trigger signal and sending the protection trigger signal to the user associated terminal. If the low-voltage line or equipment monitored by the leakage protector is short-circuited, zero-breaking faults can be generated.
For example, if the line of the current voltage signal is disconnected or the phase has no voltage value, it may be determined that the earth leakage protector detects a phase-missing fault or a zero-missing fault: if the current voltage signal has a phase without a voltage value, judging that the leakage protector detects a phase-lacking fault; and if the current voltage signal has a line break, judging that the leakage protector detects a zero-breaking fault. For example, the open-phase action time of the open-phase protection may be set to be less than 1S.

The embodiment can also determine the fault type detected by the leakage protector, and add the fault type to the leakage alarm prompt message to prompt the user of the current fault type detected by the leakage protector. The fault types include, but are not limited to, leakage faults, undervoltage faults, overvoltage faults, zero-fault faults, and open-phase faults.
According to the technical scheme of the embodiment, the leakage protector can also detect overload, short circuit, undervoltage or open phase of the low-voltage line or equipment, and has the protection functions of overload, leakage, short circuit, undervoltage, open phase and the like of the low-voltage line or equipment.
