Description
Technical field
The present invention relates to a kind of distributed wireless Simultaneous Oxidation zinc lightning arrester measuring device with electricity and method, belong to intelligent T & D Technology field.
Background technology
Metal oxide arrester MOA is universally acknowledged most advanced lightning protection electrical equipment in the present age.Bear the factor impacts such as system voltage, superpotential, filth and internal wetted due to Zinc-Oxide Arrester for a long time, make its decreasing insulating, nonlinear characteristic lost efficacy, cause MOA aging, even explode, not only cause huge economic loss, and serious threat is to the safe operation of electrical network.Therefore, the insulating property of lightning arrester are tested, can find early and fix a breakdown, the generation of Accident prevention.
Zinc-Oxide Arrester carrys out its operation characteristic of comprehensive descision mainly through the ac leakage current under live detection working voltage and offline inspection.Wired connection is passed through between the voltage sensor of traditional Zinc-Oxide Arrester live detection instrument and current sensor, when voltage acquisition point is distant from tested lightning arrester, can only solve by lengthening cable or changing voltage acquisition point, not only easily coupling and the more interference of superposition, and add workload to field staff, complexity and operational risk, some instruments by adopting radio frequency point-to-point or GPRS low-speed wireless transmission data between voltage sensor and current sensor, but the collection of three-phase lightning protector leakage current still needs 3 groups of measurement cables to be connected to each lightning arrester measures, do not realize wireless penetration completely.In addition, the general volume of current zinc oxide arrester tester is comparatively large, cable and accessory numerous, one set of instrument once can only detect 3 of a same circuit lightning arrester.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect that traditional Zinc-Oxide Arrester live detection instrument volume is large, cable accessory is numerous, do not possess complete wireless penetration, once can only survey same circuit 3 lightning arresters, a kind of distributed wireless Simultaneous Oxidation zinc lightning arrester measuring device with electricity and method are provided.
The present invention adopts following technical scheme: a kind of distributed wireless Simultaneous Oxidation zinc lightning arrester measuring device with electricity, it is characterized in that, comprise wireless base station, Leakage Current collecting unit, reference voltage collecting unit, operating terminal, described operating terminal by WLAN (wireless local area network) respectively with described Leakage Current collecting unit, described reference voltage collecting unit communicates to connect, described wireless base station is by the external GPS/BD satellite of mobile wireless network, described wireless base station and described GPS/BD passing of satelline mobile wireless network respectively with described Leakage Current collecting unit, described reference voltage collecting unit is connected.
Preferably, described wireless base station comprises wireless network access module, wireless radiofrequency time service main website, battery, described wireless network access module be used to provide can more than sighting distance 1km WLAN cover; Described wireless radiofrequency time service main website comprises wireless radiofrequency sync identification module, wireless radiofrequency clock time service module, described wireless radiofrequency sync identification module obtains precision clock by GPS/BD satellite, the built-in high precision of described wireless radiofrequency sync identification module is kept time module, even if with synchronous GPS/BD satellite lost contact, also can ensure that clock synchronous network continues to run; The digital signal that described wireless radiofrequency clock time service module is used for temporal information to be converted to radio-frequency range sends, and provides the indoor and outdoor wireless radiofrequency clock time service network coverage of more than 500m; Described battery is used for powering to wireless base station.
Preferably, described leakage current collection unit comprises current transformer, modulate circuit, AD, CPU, GPS/BD clock time service module, radio frequency clock synchronization module, wireless network card, antenna, display screen and battery; Described current transformer is connected with described modulate circuit, described modulate circuit is connected with described AD, described AD is connected with described CPU, described CPU is connected with described wireless network card, described wireless network card is connected into WLAN (wireless local area network), and described GPS/BD clock time service module, described radio frequency clock synchronization module are connected with described CPU respectively; Described modulate circuit is used for regulating current signal, and described battery is used for powering to described leakage current collection unit.
Preferably, described leakage current collection unit can reach 250 at most, every 3 described leakage current collection unit are classified as one group, and each is organized described leakage current collection unit and possesses and independently organize ID, and each described leakage current collection unit possesses independently No. ID, unit and network IP; Each organizes described leakage current collection unit can carry out Leakage Current data acquisition to A, B, C3 phase lightning arrester, each described Leakage Current collecting unit carries out leakage current data collection to a lightning arrester separately, described Leakage Current data upload to WLAN (wireless local area network) by described wireless network card, connect between described Leakage Current collecting unit without the need to cable.
Preferably, described leakage current collection unit is also provided with electronic label identification module, described electronic label identification module is used for when live detection by identifying that lightning arrester electronic labeling information reads lightning arrester facility information automatically, and corresponding lightning arrester information is automatically uploaded when uploading the leakage current data of collection, realize automatic binding and the record of live detection data.
Preferably, described reference voltage collecting unit comprises voltage transformer (VT), modulate circuit, AD, CPU, GPS/BD clock time service module, radio frequency clock synchronization module, wireless network card, antenna, display screen and battery, described voltage transformer (VT) is connected with described modulate circuit, described modulate circuit is connected with described AD, described AD is connected with described CPU, described CPU is connected with described wireless network card, described wireless network card is connected into WLAN (wireless local area network), and described GPS/BD clock time service module, described radio frequency clock synchronization module are connected with described CPU respectively; Described modulate circuit is used for regulation voltage signal, and described battery is used for powering to described reference voltage collecting unit.
Preferably, described operating terminal is smart machine, and described smart machine is notebook computer or mobile phone or panel computer.
The present invention also proposes a kind of distributed wireless Simultaneous Oxidation zinc lightning arrester live detection method, it is characterized in that, comprises the steps:
Wireless base station places by SS1, power-on;
SS2 accesses voltage transformer secondary terminal with reference to voltage acquisition unit, power-on;
Leakage current collection unit is received tested lightning arrester relevant position by SS3, first use Leakage Current collecting unit to scan tested lightning arrester electronic tag before wiring and read lightning arrester facility information, lightning arrester facility information is manually inputted without during electronic tag, can disposablely connect multiple, even the lightning arrester in whole station is all connected, power-on;
SS4 opening operation terminal, the leakage current collection unit that autoscan or manual configuration have connected, associates corresponding with actual lightning arrester for leakage current collection unit group ID and single leakage current collection unit ID;
