Description
Technical field
The present invention relates to transformer station's sensing detection equipment, be specially a kind of induction energy fetching formula oil quality sensor for transformer station.
Background technology
Although on-Line Monitor Device is applied more and more in electrical network, but because a lot of device is very unripe technically, its operation stability is poor, function is also left to be desired, practical situations shows, early stage monitoring device many existence design is unreasonable, the problem such as inaccurate, especially for the sensor monitoring of oil-filled equipment oil parameter, the converting equipment on-line monitoring technique of relative maturity application has transformer, the apparatus local discharge such as GIS and potting breaker is monitored, Chromatographic Analysis of Transformer oil, capacitive equipment electric capacity and dielectric loss live testing, Leakage Current of Zinc-oxide Lightning Arresters is monitored, infrared measurement of temperature, UV detect etc., still there is no safety, reliably, the technological means be suitable for.So for oily sensing detection, need to consider new technology and new technology carries out Improvement and perfection, improve its stability and accuracy, guarantee the reliability in the sole mass of sensor vitals and in-site measurement, the effect of on-line monitoring could be improved.
Meanwhile, the sensing device of a large amount of on-line monitoring is disperseed application, and its power supply technique exists significant limitation, and according to powered battery, then battery originally exists potential safety hazard in high voltage and strong electromagnetic environment; Under limited battery electric quantity supply prerequisite, real-time property is poor; The maintenance cost of periodic replacement is huge; Respond to power taking according to CT, then respond to electricity getting device volume comparatively large, in narrow space, difficulty is installed; Complex installation process, the time cycle is long; The real-time change of bus current causes electric power system to occur impacting and damaging, and the electromagnetic interference (EMI) of transformer station's complexity also can directly cause circuit working abnormal simultaneously, the easy loss of temperature measuring equipment, and security, reliability are lower.
Summary of the invention
The present invention lacks the problem of safety, the oily checkout equipment of transformer station that is reliable, that be suitable in order to solve, provide a kind of induction energy fetching formula oil quality sensor for transformer station.
The present invention adopts following technical scheme to realize: for the induction energy fetching formula oil quality sensor of transformer station, comprise oily sensing unit, oil sensing unit is connected to data processing unit, data processing unit is connected with correspondence with foreign country unit, oil sensing unit, data processing unit, data processing unit are all connected to supply device, supply device comprises induction energy fetching device, and induction energy fetching device is connected with accumulator by regulator rectifier circuit.
Induction energy fetching device is electric field energy energy-collecting device, is to be placed in alternating electric field with plate condenser, and its two ends induce current/voltage, and electric field energy is converted to electric energy, power to load; Regulator rectifier circuit is by an integrated low-loss rectifier and an efficient voltage reducing type converter, with the high-tension apparatus coupling energy by producing in collection environment, then this energy conversion is become the output of well-tuned, for oily sensing unit, data processing unit and correspondence with foreign country unit provide energy.Induction energy fetching technology is applied in sensing device, on the one hand, decrease complexity and the degree of difficulty of supply source, can make rational use of resources, on the other hand, rectifier is added in the power supply unit of induction energy fetching, reducing transformer, accumulator and mu balanced circuit, can effectively avoid transmission line of electricity to get under big current can to absorb energy surplus and scaling loss power circuit by unit, reduce the thermal value of power supply, and unnecessary absorbing energy effectively is stored, and can avoid transmission line of electricity electric current be small area analysis or power-off when cause the electricity shortage of monitoring equipment, ensure that draw-out power supply can to the direct current of monitoring equipment stable output, ensure that monitoring equipment lasting stability is run, and it is saturated to prevent getting energy unit, and enables to get and can send momentary high power by unit, strengthen draw-out power supply carrying load ability and adaptive faculty.Oil sensing unit is the sensor made based on surface acoustic wave principle, sensor critical piece is quartz crystal and interdigital transducer, its serviceable life is identical with monitored equipment, stable status monitoring is carried out to main equipment with regard to both having ensured that on-Line Monitor Device is sustainable like this, it also avoid because on-Line Monitor Device integrity problem produces harmful effect to the operation maintenance of main equipment simultaneously, can be used for viscosity measurement, conductivity, specific inductive capacity and dielectric loss measurement; Data processing unit provides the functions such as filtering, amplification, down coversion, transmission frequency control, the signal that oily sensing unit gathers is converted to the digital signal that background acquisition controller can directly process; Correspondence with foreign country unit can complete the data communication function of single device internal sensor to background acquisition controller, realize the wireless security isolation between electrical equipment online supervision device height electronegative potential, induction energy fetching device has features such as adapting to various inclement weather, round-the-clock reliable and stable power supply, long-term non-maintaining operation, thus overcome all weak points that are solar powered and traditional CT way to take power, become the excellent selection solving a built-in unit energy supply difficult problem.
Above-mentioned oily sensing unit, data processing unit, correspondence with foreign country unit, induction energy fetching device etc. are existing product, and its circuit design and control mode are that those skilled in the art easily realize.
Beneficial effect of the present invention is as follows: the present invention utilizes oily sensing unit and induction energy fetching device, achieves the on-line monitoring of transformer station's oil.Sensor of the present invention is based on surface acoustic wave techniques, without the need to using electronic devices and components and any supply unit, achieve the status monitoring mode of passive and wireless, effectively solve traditional on-Line Monitor Device Problems existing in security, reliability, stability etc., be highly suitable for working in high pressure, strong electromagnetic environment, make staff can grasp equipment state more in time, accurately, all sidedly.
