Abstract
The utility model discloses a portable partial discharge detector of improved generation, include: the host computer and with the external power source that the host computer is connected, the host computer includes mainboard, built -in lithium cell, 4 blocks of high frequency boards, wireless module, wireless module passes through wireless transmission with signal transmission to system backstage. The detector both can be supplied power by external power source, also can supply power inside lithium cell work normal operating in sustainable six hours by inside lithium cell, super high frequency electric magnetic wave signal is received to the sensor, transferes the authenticity of host computer, assurance data through coaxial cable, the detector has increased wireless module, has unlimited transmit system, and the host computer only need be with the help of the unlimited emitter of detector itself, and just can realize the backstage and to the wireless communication of equipment, carry out data analysis, easy operation is practical convenient.
Description
Technical field
The utility model relates to a kind of improved portable Partial discharge detector.
Background technology
Existing Partial discharge detector primarily of sensor, signal acquisition module, signal processing module, signal transmission module, daemon software form; Sensor is installed on scene to be needed on the collection point of collection signal, signal acquisition module, signal processing module and signal transmission module are unified is arranged on main frame inside, IED main frame is put in abbreviation office, be arranged in Control Room by RS485 communications protocol backstage turntable, when signal processing module delivers to signal transmission module the signal handled well, the signal sent only has discharge off, discharge capacity size.Existing technical disadvantages does not have wireless transmission function, can only limit and carry out communication with netting twine and backstage; Operation inconvenience, consistency operation personnel will follow testing staff to an on-the-spot biconditional operation, detect inconvenient.
Utility model content
For above-mentioned technical matters, the utility model discloses a kind of improved portable Partial discharge detector, comprising: main frame and the external power source be connected with described main frame; Described main frame comprises mainboard, built-in lithium battery, 4 pieces of high frequency plates, wireless modules; Described wireless module by wireless transmission by Signal transmissions to system background.
Preferably, described high frequency plate is connected with sensor by concentric cable.
The beneficial effects of the utility model are that described detector both can external power source, also can inner lithium battery power supply, and inner lithium battery work normally runs for sustainable six hours; Sensor receives uhf electromagnetic wave signal, passes to main frame through concentric cable, ensures the authenticity of data; Described detector adds wireless module, has wireless transmissions function, and main frame only needs, by the unlimited emitter of detector itself, just can realize the wireless telecommunications of backstage to equipment, carry out data analysis, simple to operate, practical and convenient.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of improved portable Partial discharge detector described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to instructions word to make those skilled in the art.
As shown in the figure, the utility model discloses a kind of improved portable Partial discharge detector, comprising: main frame and the external power source be connected with described main frame; Described main frame comprises mainboard, built-in lithium battery, 4 pieces of high frequency plates, wireless modules; Described wireless module by wireless transmission by Signal transmissions to system background.Described high frequency plate is connected with sensor by concentric cable.Described detector both can external power source, also can inner lithium battery power supply, and inner lithium battery work normally runs for sustainable six hours; Sensor receives uhf electromagnetic wave signal, passes to main frame through concentric cable, ensures the authenticity of data; Described detector adds wireless module, has wireless transmission function, and main frame only needs, by the unlimited emitter of detector itself, just can realize the wireless telecommunications of backstage to equipment, carry out data analysis, simple to operate, practical and convenient.Specifically, being received the uhf electromagnetic wave signal of detected device by outside ultrahigh frequency (UHF) sensor, passing to main frame through concentric cable, in order to ensure the authenticity of data, coaxial cable length specifies 15 meters, 15 meters of signal attenuation 1.5dB.After signal enters main frame, first by high-frequency signal plate, in high frequency plate, the deamplification of 1.5dB is supplemented if any signal, and the ultrahigh-frequency signal filtered within the scope of 500MHZ-1500MHZ, after amplification and analysis of neural network, filtering part noise signal, transfer signals to mainboard, carry out providing process in mainboard after, form three-dimensional collection of illustrative plates, again spectrum data there is network cable transmission to background analysis software through RJ45 communication protocol, because this equipment has wireless transmissions function, equipment is a wireless signal transmission base station inherently, main frame only needs infinitely to launch software by this base station, just can realize the wireless telecommunications of backstage to equipment, by backstage firing order, main frame just can make response after receiving instruction, can the operation of remote control main frame, backstage sends Signal transmissions instruction, and the three-dimensional collection of illustrative plates collected will be sent to backstage with the transfer rate of 60MHz by main frame automatically, carries out further data analysis.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in instructions and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
