Description

Electric leak detecting device

Technical field

The utility model relates to detection of electrical leakage technical field, relates in particular to a kind of electric leak detecting device.

Background technology

In existing municipal electric power system; each branched line and resident resident family are generally all provided with earth leakage protective device; but draw disorderly and pull because circuit year is for a long time aging or private; often there is leaky; earth leakage protective device often moves tripping operation; the trouble point of leakage current can not promptly and accurately be got rid of again, directly has influence on from household electric. For this reason, earth leakage protective device is removed by a lot of resident families, changes chopper switch or air switch into. Like this, in the time that leakage current reaches certain value, cause upper level earth leakage protective device action tripping operation, even cause the tripping operation of transformer secondary main switch, cause large area resident family to have a power failure, bring many troubles to looking up the fault point afterwards.

The electric leak detecting device coming into operation in the market mainly contains two classes: 1, hand-held leakage detector, and need hand-held leakage current detector at the scene to detect every part of circuit, find possible drain wire waypoint, then take certain measure; 2, failure detector is installed in field erected intelligent electric energy meter device, sends leak current fault record by the communication system of intelligent electric energy meter device.

For hand-held leakage detector, main drawback has: 1, need to be detected at the scene by staff, which rank of Field Force's (after protection switch) after fault occurs cannot failure judgement occur at, need power on step by step could progressively detect which rank of occurs in, which point is fault source, workload is huge and have an electricity consumption risk (original fault reproduction); If 2, field condition wiring is complicated, increase staff's work safety risk; If 3 have multiple electric leakages position, and occur leak current fault in the time of different periods, the work of different electrical appliance, fault judgement needs duplicate detection, sometimes may need many people to detect simultaneously, increases human cost; 4, can only manual record phenomenon of the failure, place, time, easily make the mistake, can not automatically record corresponding failure place and fault parameter. 5, the leakage current value cannot capture fault generation time, can not provide foundation for failure prevention.

For the failure detector being installed in intelligent electric energy meter device, main drawback has: 1, existing intelligent electric energy meter meter is not equipped with the data-interface that can receive earth leakage protective device response protection/detection, and erecting bed need to be reformulated standard and all change as needs increase the existing intelligent electric energy meter of earth leakage detection functions; 2, leak current fault phenomenon mainly for be that fringe area, villages within the city, commercial power and residential electricity consumption intersect and mix territory of use; and circuit excludes after loading onto earth leakage protective device after leak current fault and do not need to continue to use leakage monitoring device, all change to use with the intelligent electric energy meter of leakage current detect function and will form huge fund and the waste of project installation manpower.
