The whole system and equipment of this product consists of global positioning system, base station cluster, server cluster, 2G/3G/4G communication network,315MHz/433MHz wireless communication module, handheld receiver, detector (acquisition terminal),GPS antenna,4G antenna,4G card, telescopic insulation rod, etc
Global Positioning System (GPS) : Base stations and hand-held receivers all have built-in six-in-one multi-mode satellite timing modules to support a variety of satellite navigation systems, including China's BDS (Beidou Navigation Satellite System), GPS of the United States, GLONASS of Russia, GALILEO of the European Union, QZSS of Japan, and satellite augmenters SBAS (WAAS,EGNOS,GAGAN,MSAS), contain 32 tracking channels that can simultaneously receive GNSS signals from six satellite timing systems, and And realize joint timing and positioning, to ensure the accuracy of the test
Base station group: Base station group consists of a plurality of base stations, the system design can be compatible 255 base stations. Base stations with all cast aluminum shell, waterproof design, installed in the secondary output end of 10kV transformer. Its built-in GPS module,4G module and 315MHz/433MHz wireless communication module serve as reference standard source. The base station transmits the collected phase, frequency and other signals to the server through the Internet. The data detected by the base station serves as the comparison standard source, and the data detected by the collector is compared with the source data of the base station
Server farm: Multiple servers form a server farm. The server can receive data from the base station, handheld receiver, and collector respectively. The server will first analyze and compare the data of the collector and the data of the base station, obtain the phase difference and other parameters, and then send the analysis results to the hand-held receiver, hand-held receiver users can receive real-time phase information detected by any collector, can accurately identify the standard Phase A, phase B, phase C, including the basement without any communication signal ce phase core phase, and unified color code work
Detector: nuclear phase, current different functions of the detector, detector are built GPS module,4G module,315MHz/433MHz wireless communication module, in which the current detector integrated hook design, built-in multi-layer flexible coil,315MHz/433MHz wireless communication module is easy to use handheld receiver for short distance meter reading; GPS module and 4G module communicate with the server and transmit data; Multilayer flexible coil is used to collect current and current waveform, frequency, phase and other signals
Flexible coil: namely The Rogowski Coil, using the multilayer Roche coil technology, is an annular coil wrapped uniformly over a non-ferromagnetic material. The multilayer coil has no hysteresis effect and virtually zero phase error. The lower the phase error, the more accurate the high voltage nuclear phase is. Flexible coil no magnetic saturation phenomenon, high linearity, can meet the test current. The output signal is the differential of the current with respect to time. By integrating the output voltage signal, the input current can be truly restored. The measured current range can be from milliamps to tens of thousands of amps. The purpose of using multi-layer flexible coil is to improve the resolution of leakage current detection, can reach 10mA, and solve the test of large current, high harmonic current (up to 400 times), complex waveform current, transient impulse current and restore its waveform
Hand-held receiver: Using 3.5 "true color LCD screen design, built-in GPS module,4G module,315MHz/433MHz wireless communication module, to receive the data sent by the server, but also to the collector, base station meter reading. The receiver disys real-time phase, frequency, current and other information on the same screen, with "X signal normal,Y signal normal,A phase,B phase,C phase, same phase, different phase" and other voice prompts, clear and intuitive, different functions of the receiver disy content is different
Insulation rod: telescopic insulation rod, the length after stretching is about 3 meters, about 0.6 meters after shrinkage, light, with moisture-proof, high temperature resistance, impact resistance, high insulation, telescopic and other characteristics, connected to the collector, can be hung in the line test, can also be lengthening or reducing the length of the insulation rod according to the actual needs
Nuclear phase: Common nuclear phase distance on open ground can reach 160m, satellite timing nuclear phase distance is greater than 500km, can be used for 1V ~ 550kV voltage lines all intelligent nuclear phase, can also be used for high-voltage lines and fully sealed ring network cabinet low-voltage induction point nuclear phase, in which the bare wire detector below 35kV can directly contact the nuclear phase, bare wire above 35kV using non-contact nuclear Phase, non-contact nuclear phase is to gradually close the detector to the wire under test, when the electric field signal can be induced to complete the nuclear phase, so there is no need to contact the high voltage wire directly, safe and reliable!
