Description
Technical field
The present invention relates to a kind of high-voltage electriferous display locking device, be specially a kind of demonstration locking device of indicating high-tension power transmission and transformation equipment and circuit charged state.
Background technology
In electric power system, high-voltage electriferous display locking device is the important safety equipment that whether high-tension apparatus and circuit is had detection, indication and locking that high-tension electricity carries out, prevent charged mistake splice grafting ground disconnecting link or misconnection earth connection, or it is electric to be with ground connection disconnecting link, earth connection to misdeliver, assurance personnel and device security.
Present high-voltage electriferous display locking device has multiple, but mainly contain two kinds: first kind of mode is contact high-voltage capacitance transducer, but because contact high-voltage capacitance transducer directly links to each other with high voltage bus, when problems such as product workmanship, serviceability deterioration, overvoltage occurring, cause the high-voltage capacitance transducer breakdown easily, cause security incident, so security performance is relatively poor; Second kind is that non-contact capacitance induction formula electrification in high voltage shows locking device, the danger that this mode is not broken down by high-voltage, but detection signal is subject to the influence of weather, electrical network cabling mode, if the circuit of different electric pressures is when just arranging, influence each other, just can't detect effectively.
Summary of the invention
For overcoming above-mentioned defective, the invention provides a kind of high-voltage electriferous display locking device, it is not only safe in utilization, detection is reliable, and need not to specialize in the operate as normal that power supply can be realized the electric field energy acquisition module.
For realizing such scheme, technical scheme of the present invention is: comprise electric field energy acquisition module and display control module, described display control module comprises indicative control unit, radio communication is accepted the 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 links to each other with the input of radio communication transmitter unit;
Described electric field energy collecting unit comprises the electric field energy collection line that is electrically connected successively, rectification circuit, filter circuit, accumulator, voltage stabilizing circuit, it is unsettled as two input one ends of rectification circuit that described electric field energy is gathered line, and the other end connects 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 the voltage stabilizing circuit, guarantees the operate as normal of microcontroller with this.
As the preferred embodiments of the present invention: 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 SAW (Surface Acoustic Wave) device is used in high-voltage electriferous display locking device.
In order to prevent interference from outside signals, guarantee the work of the long-term stability of module, described electric field energy acquisition module is placed in the insulation protection box.
The present invention gathers the high-tension apparatus electric field energy by the electric field energy acquisition module, gives power supplies such as microcontroller, wireless transmitting unit through the electric field energy collecting unit, makes system's operate as normal; 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 present invention 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.The of paramount importance the present invention of being utilizes the electric field energy collecting unit to detect and is the power supply of follow-up unit, power supply separately, having solved contact testing product on the high-tension apparatus needs often to have a power failure and changes the power taking puzzlement of battery etc., improve the dependability of this device greatly, the later maintenance expense is lower, has very high practical value.
