Background technology
In electric power system, the passive and wireless transmission system is the important safety equipment of detection, indication and locking that whether high-tension apparatus and circuit are carried out with high-tension electricity, prevent charged mistake splice grafting ground disconnecting link or misconnection earth connection, or be with grounding switch, earth connection misdelivery electricity, assurance personnel and device security.
Current passive and wireless transmission system has multiple, but mainly contain two kinds: first kind of way is contact high-voltage capacitance transducer, but because contact high-voltage capacitance transducer directly is connected with high voltage bus, when the problems such as product workmanship, serviceability are deteriorated, overvoltage occurring, easily cause the high-voltage capacitance transducer breakdown, cause security incident, therefore security performance is poor; The second is non-contact capacitance induction formula HV live displaying locking device, the danger that this mode is not broken down by high-voltage, but detection signal is subject to the impact of weather, electrical network cabling mode, if the circuit of different electric pressures is while just arranging, influence each other, just can't effectively detect.
The utility model content
For overcoming above-mentioned defect, the utility model provides a kind of passive and wireless transmission system, its not only safety, detect reliable, and without specializing in the normal operation that power supply can real electric field energy acquisition module.
For realizing such scheme, the technical solution of the utility model is: comprise electric field energy acquisition module and display control module, described display control module comprises indicative control unit, the radio communication receiving unit, described electric field energy acquisition module comprises the electric field energy collecting unit, microcontroller and radio communication transmitter unit; The output of described electric field energy collecting unit is connected with the power end of microcontroller, and the signal output part of described microcontroller is connected with the input of radio communication transmitter unit;
Described electric field energy collecting unit comprises that the electric field energy be electrically connected to successively gathers line, rectification circuit, filter circuit, accumulator, voltage stabilizing circuit, it is unsettled as two input one ends of rectification circuit that described electric field energy gathers line, and the other end is located at the high-tension apparatus surface.
In order to improve the stability of electric field energy acquisition module work, described electric field energy collecting unit also comprises anti-overvoltage crowbar, and described anti-overvoltage crowbar is located between accumulator and voltage stabilizing circuit, with this, guarantees the normal operation of microcontroller.
As preferred embodiment of the present utility model: described radio communication transmitter unit adopts the radio frequency unit based on SAW (Surface Acoustic Wave) resonator, and its emission is low in energy consumption, and the emission current peak value is not more than 2mA.Thereby started the precedent that surface acoustic wave device uses in the passive and wireless transmission system.
In order to prevent the interference of outer signals, guarantee the work of the long-term stability of module, described electric field energy acquisition module is placed in insulation protecting box.
The utility model gathers the high-tension apparatus electric field energy by the electric field energy acquisition module, through the electric field energy collecting unit, to power supplies such as microcontroller, wireless transmitting unit, makes the system normal operation; When high-tension apparatus has a power failure, utilize accumulator to send out power cut signal to microcontroller, IMU is crossed radio frequency unit and is transmitted power failure information to main frame, thereby realizes the reliable Detection to high-tension apparatus.The utility model has not only solved the drawback of original technology detecting method; Its electric field energy collecting part adopts contact measurement, and detection accuracy and interference free performance are greatly enhanced; Partial message transmission adopts wireless mode, avoids electric field energy acquisition module ground connection, and fail safe is good.Most importantly the utility model utilizes the electric field energy collecting unit to detect and is the power supply of follow-up unit, power supply separately, having solved on the high-tension apparatus contact measurement product needed often has a power failure and to change the puzzlement of battery, greatly improve the dependability of this device, the later maintenance expense is lower, has very high practical value.
