At present, be limited by the backwardness of equipment and method, anti-electricity-theft investigation efficiency is lower, and difficulty is more.The first, technical equipment falls behind: power utility check equipment is mainly the traditional instruments such as electric energy meter on-site calibrator, multimeter, phase meter.The second, method falls behind: traditional inspection of opposing electricity-stealing, and metrological personnel and power utility check personnel must arrive scene and could carry out, and time efficiency is low, and electricity filching person has time enough to eliminate stealing evidence.Three, enforcement difficulty is large: due to client's actual load is not understood, it is large that some stealing modes of taking for primary equipment, measuring apparatus inside are investigated and prosecuted difficulty, such as changing current transformer, at electric energy meter, the inner remote control stealing equipment etc. of installing of test connecting box.Four, may affect the good service work of enterprise: will carry out further inspection for the client who has stealing suspicion, may need to have a power failure and could carry out, if it is passive not find that stealing evidence can bring to work such as good service, Moral Culture Constructions after having a power failure.
Traditional power utility check only checks user's secondary side measuring apparatus and loop, if can install a measuring equipment additional at circuit primary side, primary side electric parameter data and user's secondary side power information data are contrasted, can find easily user's electricity filching behavior; In the time that obvious deviation appears in user's secondary side electric parameter and primary side electric parameter, can judge that this user exists electricity filching behavior.
Utility model content
The purpose of this utility model is to provide a kind of high pressure direct access fault detection device, to find user's electricity filching behavior.
The technical scheme that realizes the utility model object is as follows: a kind of high pressure direct access fault detection device, and signals collecting sending module is made up of the 10KV high-tension current potential collecting unit, data merge cells and the wireless signal transmitting element that connect successively; Signal processing module comprises controlling processes core, and data-interface, secondary data interface, main website data-interface and a man-machine interface are connected respectively to control processes core; The wireless signal transmitting element of signals collecting sending module is connected to a data-interface of signal processing and control module by wireless channel; The main website data-interface of signal processing and control module is connected to main station system by wireless channel.
Further, also comprise extension type insulating bar, signals collecting sending module is fixedly attached to extension type insulating bar one end.
The beneficial effects of the utility model are, high pressure direct access fault detection device can be realized functions such as primary side and secondary side parameter measurement, data collection and analysis, abnormal conditions warning, data storage, statement analysis; Can be fast, accurately, easily the electricity filching behavior existing in user's secondary side measuring apparatus and loop is detected, be judged and and alarm, effectively stop all kinds of electricity filching behaviors and provide foundation for electric quantity compensating.

Wherein, 1,10KV high-pressure side, 2, transformer, 3,220V/380V low-pressure side.
Embodiment
As shown in Figure 1, high pressure direct access fault detection device is made up of signals collecting sending module, signal processing and control module and main station system.
Signals collecting sending module: formed by 10KV current/voltage collecting unit, data merge cells, wireless signal transmitting element; 10kV high voltage side current, voltage acquisition are realized, the function of analog/digital signal conversion and data wireless encrypted transmission.It is low-voltage, little electric current by primary side high voltage, large current conversion that current/voltage collecting unit adopts the mode of high-voltage capacitance dividing potential drop and high pressure pincerlike meter; Low-voltage, little current analog signal are converted to the Frame with certain format by data merge cells; Wireless signal transmitting element adopts micropower wireless encryption technology that this Frame is sent to signal processing and control module.
Signal processing and control module: formed by control processing core, data-interface, secondary data interface, main website data-interface and a man-machine interface; Be the core of a whole set of electricity filching device, realized reception, calculating, the analyzing and processing of data, parameter display, the functions such as function setting and data telecommunications.A data-interface is micropower wireless signal receiver, receives the wireless data frame from the transmission of signals collecting sending module, and is sent into control and process core.Secondary data interface comprises a RS485 interface, and the direct reading power meters operational factor that can be connected with electric energy meter RS485 interface, as voltage, electric current, power factor etc.; In addition secondary data interface also comprises a wireless data interface, can receive the wireless data that power information acquisition terminal sends; The multiple compatibility of second interface is conducive to carrying out of site work, can select according to different actual conditions the reading manner of secondary data.Control processing core and adopt high-performance embedded MCU chip, its built-in embedded program calculates, processes, compares, judges a secondary data and secondary data; The threshold values of setting according to user, in the time that primary side electric parameter and secondary side electric parameter deviation exceed this threshold values, there is the concurrent alerting signal of sending of electricity filching behavior in programmed decision user.Man-machine interface adopts touch display screen as medium, can show the parameter such as voltage, electric current, power of current primary side and secondary side, in the time that user exists electricity filching behavior, can point out warning message; The procurator of electricity consumption simultaneously can check unit state, setting device parameter by touch-screen, as mutual inductor ratio, secondary side rated current etc.First and second side electric parameter data and fault detection result, alerting signal etc. are uploaded to Surveillance center's main station system by the communication mode that main website data-interface adopts GPRS/CDMA.
