Description
Technical field
The utility model relates to usage data treating apparatus field, especially relates to a kind of platform district recognition combination device.
Background technology
In the operating management of low-voltage network, management of power use department is the needs of the target assessment realizing marketing fine-grained management and complete consumption reduction impairment, carrying out power distribution station generaI investigation is a necessary measure, and the use of the function instruments such as station user identification apparatus is indispensable, it can investigate thoroughly that where mutually user is by information such as which platform transformer, that circuits, even power supply, for marketing management provides accurate management data.These data ensure platform district electricity consumption load balance, the loss of reduction laod unbalance, and guarantee the basic data of platform district line loss correctness, is the basic factors realizing intelligent grid construction.Following problem is there is in what come into operation in the market based on FSK carrier wave and pulse-current technique low-voltage platform area identification equipment:
1, the uncertain problem of decipherment distance
Current like product: the Different periods for same circuit can receive carrier signal sometimes, sometimes but cannot receive.Its main cause is that the Different periods user of low voltage electric network is different to the intensity of the noise that electrical network produces, and the line impedance that Different periods user load difference causes is different.Thus cause the deep fades of carrier signal, long-distance transmissions that cannot be stable, the platform district recognition combination device based on carrier communication principle cannot reliable and stablely be identified.
2, accuracy problem is identified
Current like product: for platform district transformer altogether high pressure, altogether, the platform district of the adjacent multiple stage distribution transforming of cable duct altogether identifies, exist cannot accurately judge, feature that False Rate is high.Because the platform district recognition combination device of carrier wave principle only adopts power carrier signal to carry out user's identification, and carrier signal is high-frequency signal can be coupled to 10kV high-pressure side by substation transformer, then is transferred to adjacent distribution transforming by 10kV hi-line.ZAP cannot distinguish the same phase of this distribution transforming and adjacent distribution transforming.Thus cause " getting lines crossed " phenomenon, i.e. " high pressure is being got lines crossed altogether ";
If in like manner adjacent distribution transforming has common ground situation, carrier signal equally also can got lines crossed to adjacent distribution transforming, namely " gets lines crossed altogether "; If the low-voltage cable of adjacent distribution transforming walks same cable ditch, carrier signal can be gone here and there in other distribution transforming by the capacitive coupling between cable, i.e. " cable duct is being got lines crossed altogether ".
3, there is use inconvenience problem
Current like product: adopt pulse current pincers, the large onsite application of volume is inconvenient, and solve only the problem being solved platform district and alternate crosstalk from pusher side to host computer side by the mode of pulse current, but main frame still passes through high frequency carrier mode to from pusher side, thus it is disturbed to there is carrier signal, make the problem that can not receive recognition result from machine.Owing to adopting high-frequency carrier signal, need powerful power supply unit, thus make contour size of the unit(s) comparatively large, weight, generally at more than 1.5kg, can not meet handheld device requirement.
4,
equipment distinguishes main frame, from machine problem
Current like product: often adopt main frame, from machine mode of operation.Main frame uninterruptedly sends signal, sends signal, after main frame receives signal, feed back signal to from machine from machine Received signal strength or from machine.Evident characteristic is: main frame, completely inconsistent from machine principle of work, mode of operation.Cause production complexity to increase, and strictly must distinguish host and slave processors.
5, economy problems and multiple stage district test independent assortment problem
Current like product: due to main frame, belong to 2 kinds of different products respectively from machine, a 1 complete equipment (corresponding Ge Tai district of main frame must be used inside same district, current like product 1 cover comprises 1 main frame, one from machine), when needing to use test in NGe Tai district simultaneously, (N platform main frame, N platform are from machine must to adopt N complete equipment, the core of equipment is main frame), use cost is high.
