Description
Technical field
The present invention relates to a kind of fault monitoring device and monitoring method, more particularly to a kind of monitoring of dry-type air-core reactor
Device and monitoring method.
Background technology
Dry-type air-core reactor used in the occasions such as the current conversion 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 residing strong-electromagnetic field environment shadow
It rings, with operating load, the variation of environment temperature, compared with the influence that other equipment is easier the factors such as fever, smoothing reactor exists
Occur fever, even burning phenomenon in actual motion；In addition, since reactor in manufacture, transport, installation and uses process
In, in fact it could happen that inner surface is dirty, burr, due to poor contact etc. and the insulation defect that generates, it may occur that shelf depreciation
Phenomenon causes Reactor Fault, significantly impacts the service life of reactor, also reduces the safety of operation of power networks.Therefore it needs
The operating status of reactor is monitored.High-voltage flat-wave reactor shown in FIG. 1, usually by holder and reactor body structure
At wherein ontology is coaxial multi-layer winding.
Operations staff carries out special tour to reactor arrangement, on the one hand should using conventional infrared measurement of temperature means at present
Method needs operations staff to make an inspection tour for a long time, and maintenance is big；On the other hand since dry smoothing reactor is using hollow-core construction,
Conventional means can only measure reactor surface into trip temperature, the fever of reactor inside generation is difficult to extremely timely and effective
Monitoring, affects the actual effect monitored to device temperature.Also have using online infrared thermography detection temperature, such as patent
CN201310393608.0 " one kind preventing the round-the-clock dry reactor on-Line Monitor Device of strong magnetic and method ", but still exist not
The drawbacks of internal temperature change capable of being monitored in real time.
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 higher price and optical fiber is fragile, 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 rain cover ventilation opening setting smoke sensor device monitor the failure of reactor.Using the party
Formula monitors failure, and usual failure is very serious, cannot meet 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 operation " propose by
The method of installation IP cameras monitors Reactor Fault beside reactor, and it is that could find photograph which is only larger in failure
Machine generates the difference of picture.
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
Show shelf depreciation, but camera need to be directed at electric discharge position by the equipment, can only be used for inspection, and for the same nothing of internal fault
Can be power.
Invention content
The purpose of the present invention is overcoming the above-mentioned prior art, a kind of high pressure dry air reactor failure prison is provided
Survey device and monitoring method.The present invention detects high pressure dry air reactor failure by detecting the gas for lower generation of discharging,

The method that high pressure dry air reactor is monitored using above-mentioned fault monitoring device is as follows：
When reactor breaks down, the decomposition gas of generation enters gas piping, gas sensor by gas probe
The gas concentration detected is transferred to message processing module, gas of the message processing module comparison positioned at detection device lowest part
Probe detection to the gas concentration that arrives of gas concentration and upper gas probe detection, judge whether to generate and decompose gas, such as produce
The concentration of raw decomposition gas reaches gas concentration value described in the principle of following invention detection failures, then it is assumed that faulty production
It is raw.Further, the difference that same gas concentration is detected by comparing different location gas probe determines that failure generates accurate
Region, and further can may determine that fault severity level and fault type according to the concentration levels for generating each gas component.
The principle that the present invention detects failure is as follows：
In detection process, if only detecting O3Concentration changes, and persistently rises within a certain period of time, and other are several
Kind gas component is substantially unchanged, then it is assumed that the low-intensity electric discharge for not being related to solid insulation only occurs；
If both detecting O3Concentration changes, and detects that CO concentration changes, while holding within a certain period of time
It is continuous to rise, then it can be confirmed and the low-intensity for being related to solid insulation electric discharge have occurred.
If both detecting O3Concentration changes, and detects NO, NO2、N2O、NO3、N2O5In at least one kind of concentration hair
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.
It refers to when volumetric concentration is less than 30ppbv that the concentration, which changes, and concentration improves 20%；Concentration 30~
When between 60ppbv, concentration improves 6ppbv or more；When volumetric concentration is in 60ppbv or more, concentration improves 10%；But volume is dense
For degree in 500ppbv or more, concentration improves 5%.
According to the more intensive of above method gas probe arrangement more conducive to the region that accurate judgement failure generates, but consider
Cost and reactor operation characteristic, as long as energy failure judgement Position Approximate, you can to further determine that specific location by observation,
Therefore preferred arrangement is to be evenly arranged 3 gas probes from top to bottom in each air duct.
For running high pressure dry air reactor, the arrangement of detection device is different.The gas probe cloth
It sets inside the rain cover of high pressure dry air reactor, and is arranged on rain cover inner wall, and be circumferentially evenly arranged；It is described
