Detailed description of the invention
Embodiment one
As shown in Figure 1 to Figure 3, a kind of outside transformer substation display device, it is applicable to be arranged near the outdoor high-voltage power equipments such as transformer station's multiple-loop line ultra-high-tension power transmission line and grounding switch thereof, relatively open for outdoor equipment space, the actual features designs such as natural light is stronger, charged signal is pointed out at the enterprising line flicker of high-power light-emitting element by power amplifier, it is achieved electrical verification alarm realizes with the allomeric function highly illuminated。Device includes power module, controls module and display module, and each intermodule connects between two；Power module includes induction energy fetching device 1 and accumulator 2, and accumulator is connected with induction energy fetching device by rectification circuit；Controlling module and include the sensory package of controller and connection thereof, sensory package includes electric-field sensor 7 and humidity sensor 8；Display device includes LED illumination plate 9 and LED text importing plate 10；Induction energy fetching device includes plate condenser, and rectification circuit includes booster transformer 3 and the series resonant circuit 4 connected thereof；Controller includes dsp chip 5 and data storage 6；Display device connects power amplifier 11 and frequency controller 12, and power amplifier includes the imported OTL amplifying circuit in front end, and frequency controller includes H bridge inverter and output filter；LED illumination plate and LED text importing plate are dual-colored LED and show。
What the confession source module of apparatus of the present invention utilized is that coupling principle takes energy, power module includes induction energy fetching device and accumulator, wherein, induction energy fetching device is electric field energy energy-collecting device, it is be placed in alternating electric field with plate condenser, its two ends induce current/voltage, and electric field energy is converted to electric energy, are powered to load；Accumulator connects rectification circuit, adopt the circuit being made up of IGBT to produce high-power sinusoidal signal, after the boosted transformer boost of this signal and high-pressure series resonance circuit amplify, electric pressure is up to high pressure, supertension, extra-high voltage rank, after power amplifier amplifies, its energy multiple can more common supply device high about 30 times, according to determining energy hole, trigger by high optically focused, high brightness, high-power LED constitutes light-emitting component, do not need additional power source, even if under the background of outdoor strong sunlight in summer, also can send substantially, stable flicker light。
The effect major embodiment of this device middle controller is both ways, by the electric-field sensor in sensor group, the field intensity signal of environment of electric field is acquired on the one hand, electric-field sensor is by by an integrated low-loss commutator and an efficient voltage reducing type transducer, to voltage waveform rectification, to collect the high-tension line coupling energy produced in environment, then this energy is converted to the output of well-tuned, electric field information support is provided for controller, and determine band electrical information by controller, carry out the comparison with data storage to inquire about, by voltage strength, the information such as safe distance are transferred to display device and carry out LED text importing, wherein, electric-field sensor can also connect an external storage capacitor, it is easy to gather stable output and the self-sustaining of signal, can when the ultra low quiescent current of wide hysteresis be under-voltage, electric charge is enable to accumulate on a storage capacitor, till buck converter can send the electric charge that a part stores to output expeditiously, when without dead electricity resting state, scalable transmission voltage, give storage electric capacity charging continuously simultaneously, ensure to gather the seriality of signal。
On the other hand, the humidity sensor in sensor group air humidity is gathered, it is simple to controller judges whether to be in the weather environments such as rain, snow, mist, it is simple to the double-colored switching that LED shows。The cardinal principle of humidity sensor application is, utilize at rain, snow, greasy weather, the phenomenon that ambient air humidity is bigger than normal weather, air humidity is passed to controller, the air humidity signal of controller detection humidity sensor output, when air humidity exceedes the threshold values of setting, output switch control signal, control the conducting of switch relay, thus power supply is passed through switch contact, deliver to the yellow led lamp plate that dual-colored LED shows, carry out double-colored display, realize improving the purpose of LED illuminance under bad weather condition, not only can use at power system transformer substation outdoor lighting, it is also extrapolated to street lighting, all outdoor lighting places such as plaza lighting。
Owing to ground staff is provided visible signal mainly by LED luminescence by this device, therefore its luminous intensity needs to increase considerably, therefore power amplifier and frequency controller are introduced, make the energy that device gathers multiple many, power amplification sufficiently large, achieve the Expected Results of high light, and choose the high luminescent material of brightness, choose the color of the delicate eye to people；Adopt high optically focused, high brightness, high-power LED lamp, it is achieved that the illumination effect that power consumption is little and brightness is high；Flashing rate in display module controls system, it is achieved that stablizing of flashing rate, has stability and reliability, and the flicker frequency controlling light-emitting component makes observation personnel be comfortable on。Additionally, the periphery of power supply and electric-field sensor arranges screen layer, to avoid highfield on controlling, the impact of display device or misoperation, this device can also further expand, the comparatively perfect communication functions such as Digital Signal Processing are included as carried, with substation central control station, electrical verification warning information is carried out information be connected, adapt to the trend of industry development, play the synthesis result of security protection integration。
Embodiment two
A kind of outside transformer substation display device, device can pass through to simplify and improve, for for inside plant, indoor type is applicable to the indoor high-tension electricity equipment such as switch cubicle, complicated for indoor equipment internal structure, narrow space and relative closure, the actual features such as electromagnetic environment is complicated design, electric-field sensor is directly installed on equipment high pressure position, high voltage electric field signal is transferred to controller by transfer wire, maybe can connect radio frequency dispensing device, electric field signal is converted to radiofrequency signal send, controller connects receptor, signal is received, conversion, calculate, judge, according to equipment live situation, pass to display device and be identified display。
Owing to the present invention is indoor type device, in display module, the effect of power amplifier is very not notable, if induction energy fetching intensity own is enough, these parts can be omitted, according to determining energy hole, trigger the light-emitting component being made up of the LED of high optically focused, high brightness, it is achieved that the illumination effect that power consumption is little and brightness is high；Flashing rate in display controls system, it is achieved that stablizing of flashing rate, has stability and reliability, and the flicker frequency controlling light-emitting component makes observation personnel be comfortable on being advisable。The applied range of this kind of device scheme, its electric-field sensor can be installed on the multiple places such as switch cubicle, ring main unit, box-type substation, GIS combined electric, end, high voltage bus, line-to-ground cutter, open combined electrical apparatus, carries out the live detection under varying environment。
