Description
Technical field
The present invention relates to a kind of monitoring devices of dry-type air-core reactor.
Background technique
Dry-type air-core reactor used in the occasions such as the converter station of extra-high voltage direct-current transmission, operation and maintenance and on-line monitoring
Technology is still in the experience accumulation stage.By reactor own structural characteristics, manufacturing process and locating strong-electromagnetic field environment shadow
It rings, with operating load, the variation of environment temperature, compared with the influence that other equipment are easier the factors such as fever；In addition, due to reactance
Device is in manufacture, transport, installation and use process, in fact it could happen that since inner surface is dirty, burr, produces due to poor contact etc.
Raw insulation defect, it may occur that partial discharge phenomenon causes Reactor Fault, significantly impacts the service life of reactor, also reduces
The safety of operation of power networks.Therefore it needs to be monitored the operating status of reactor.High-voltage flat-wave reactance shown in FIG. 1
Device is usually made of insulating support, reactor body and rainhat, and wherein ontology is coaxial multi-layer winding.
Operations staff carries out special tour to reactor arrangement, also there is use using conventional infrared measurement of temperature means at present
Online infrared thermal imager detection temperature, as " one kind prevents the round-the-clock dry type electricity of strong magnetic to patent CN201310393608.0
Anti- device on-Line Monitor Device and method ", but since dry smoothing reactor is using hollow structure, conventional means can only be to electricity
Anti- device surface carries out temperature measurement, and the fever that reactor inside occurs is difficult to timely and effective monitoring extremely, affects to setting
The actual effect of standby temperature monitoring.
Based on this, patent CN201320792365.3 " the ultra-high voltage converter station dry reactor temperature based on optics thermometric
Monitoring device " proposes to be monitored the temperature inside reactor using the method for laying optical fiber grating temperature sensor.But it should
Mode price is higher and optical fiber is easy to damage, while this method cannot achieve monitoring for discharge fault.
Patent CN201320153922.7 " a kind of dry reactor On-line Fault monitoring device " is proposed by reactor
The lower section of insulation column and the method for rainhat ventilation opening setting smoke sensor device monitor the failure of reactor.Using the party
Formula monitors failure, and usual failure is very serious, is not able to satisfy the requirement that can be detected at failure initial stage.In addition, the sensor exists
Performance is unstable under the conditions of dust, sleet, high-intensity magnetic field.
The patent CN201410551617.2 vision system of dry reactor strain detecting " a kind of run " propose by
The method of installation IP camera monitors Reactor Fault beside reactor, and which could only find to take a picture when failure is larger
The difference of machine generation picture.
Patent CN 201610584725.9 " high pressure dry air reactor fault monitoring device and monitoring method " proposes logical
Detection gas component is crossed to detect reactor discharge fault, but this method needs lay gas piping in reactor, for
The reactor of labour increases layout difficulty；In addition, gas piping makes high voltage reactor ontology be connected with ground installation, although adopting
It is the pipeline of insulating materials, but increases the risks such as potential creeping discharge, reduces equipment overall security.
There is use " day is blind " ultraviolet image method at present for the fault detection of local discharge of reactor, it can be in the form of images
It shows shelf depreciation, but camera need to be directed at electric discharge position by the equipment, inspection, and nothing same for internal fault can only be used to
It can be power.
Summary of the invention
The purpose of the present invention is overcoming the above-mentioned prior art, a kind of self energizing high pressure dry air reactor is provided
Fault monitoring device.The present invention discharges the lower gas generated to detect high pressure dry air reactor failure, simultaneously by detection

Changing, while all lasting rising in addition to NO within a certain period of time, then can be confirmed and be not related to the high-strength of solid insulation
Degree electric discharge.
If both detecting O3Concentration changes, and detects NO, NO2、N2O、NO3、N2O5In it is at least one kind of, and
CO concentration changes, at the same it is all lasting in addition to NO within a certain period of time rise, then can be confirmed to have occurred and be related to solid insulation
High-intensity discharge.
The concentration change refers to when volumetric concentration be less than 30ppbv when, concentration improve 20% or this measured value with
The ratio between last time measured value is greater than 1.2；When concentration is between 30~60ppbv, concentration improves 6ppbv or more；When volumetric concentration exists
When 60ppbv or more, concentration raising 10% or the ratio between this measured value and last time measured value are greater than 1.1；But volumetric concentration exists
When 500ppbv or more, concentration raising 5% or the ratio between this measured value and last time measured value are greater than 1.05；Under any concentration, this
The ratio between secondary measured value and last time measured value continuous 5 times greater than 1.
It is had the following advantages that using above-mentioned fault monitoring device and method monitoring high pressure dry air reactor failure.Monitoring
