Description
Technical field
The invention belongs to electric system power transmission and transforming equipment fields, are related to electric system power transmission and transforming equipment runnability and health
The monitoring and analysis of state, the temp measuring system of specifically a kind of magnetic control type paralleling reactor inner-core magnet valve and thermometric side
Method.
Background technology
Currently, the output characteristics that the fixation switching type reactor in substation is adjusted by its classification, has been difficult to adapt to power grid
The dynamic passive compensation demand of requirements at the higher level；In addition to this, fixed switching reactor is in carrying out system voltage adjustment process
Frequent switching can also cause serious overvoltage problem, then lead to busbar phase fault, interphase short circuit of reactor and reactor
The failures such as turn-to-turn insulation damage, seriously threaten the safe and stable operation of power grid.For this purpose, overcoming traditional saturable reactor response speed
The magnetic control type paralleling reactor that degree is slow, loss is high, noise is big, harmonic content is abundant（MCR, Magnetic-valve
Controlled Reactance）Start to be able to extensive use, and is matched with group capacitor in original station and constitute MSVC dynamics
Reactive-load compensation is equipped, and is being presented quickly, flexibly and while continuous response characteristic, also efficiently avoid the idle tune of network voltage
Overvoltage problem caused by equipment frequent switching during section.
By the operation principle of MCR it is found that MCR is to change equivalent small section on iron core by adjusting the size of D.C. magnetic biasing
Face core packet（That is " magnet valve "）Saturation degree continuously adjust output realize reactive capability；For this purpose, compared to conventional reactor
Equipment, MCR keep its local pyrexia problem more prominent because its iron core magnet valve needs longtime running in depth saturation state.Existing
Have in technical standard, specification, traditionally oil-immersed transformer（Reactor）Pattern carry out MCR state-detections, i.e., it is logical
It crosses and carries out oil temperature detection or oil chromatogram analysis to judge the fever exception or failure of MCR.As previously mentioned, MCR inner-cores
Special construction and its operation principle so that the fever phenomenon at magnet valve is more prominent；Either oil temperature or oil chromatography detection,
All there is apparent hysteresis quality when detection fever exception or failure, i.e.,：It was found that high oil temperature or Oil Dissolved Gases Concentration are exceeded
When, iron core magnet valve inside MCR often because temperature rise it is excessively high due to cause it is irreversible badly damaged.

Its interior spatial structure is complicated and shows high pressure always, the environmental characteristic that high-intensity magnetic field interferes.For the heat of such high-tension apparatus
Point temperature measurement application, for existing thermometry, either common RTD thermal resistances（Pt100）, thermocouple（High resistant line）
Deng the electric thermometrys such as class temperature transducer or pressure-type thermometer, infrared measurement of temperature, gold can not thoroughly be solved by all facing first
The peace that category conducting wire, metal parts, shielding measure, higher-pressure region installation pressure thermometer bulb or infrared probe bring high voltage equipment insulation
Full potential problem and plain conductor and metal parts also will produce serious eddy-current loss fever in electromagnetic environment and ask
Topic；In addition to this, light current temperature signal can also be understood heavily disturbed in strong magnetic field circumstance, and there are data wander, events
The problems such as barrier rate height is reported by mistake with data so that the reliability and stability of temp measuring system can not ensure, it is difficult to provide in real time, surely
Fixed, reliable temperature information.
And the fiber Bragg grating type temperature sensor of transformer and dry-type air-core reactor temperature measuring application is common in although having
Passive, anti-electromagnetic interference capability is strong, can be applied to the characteristics of adverse circumstances, but is limited by its own technical principle and is limited, thermometric
When generally require to solve pressure, stress, temperature, vibration, the mutual comprehensive function of the environmental factors such as bending, generally require to take more
Add complicated encapsulation technology, thus is unfavorable for the single temperature physical quantity under complex space environment.
