Description
Technical field
The invention belongs to insulation deterioration detection device field, especially relate to a kind of detection oil-filled transformer insulation ag(e)ing
Device.
Background technology
Oil-immersed power transformer is one of great, key equipment of nuclear power station electric power output, oil-immersed power transformer
The life-span that is typically designed be 30 years, the actual motion life-span is generally 20～40 years, in real work, the peace of oil-filled transformer
Row for the national games and service life are all to be directly affected by the insulation ag(e)ing degree of transformator and determined.One is run at transformator
After the section time, due to electric field in running, moisture, the many external influence such as temperature and mechanical force can accelerate transformator
The aging speed of insulator, general, transformer oil can carry out regenerating or changing in transformator normal operation, so
Depend primarily on the behaviour in service of insulating board and reality the aging and service life of oil-filled transformer.The most large-scale
Power transformer have an accident when properly functioning, may result in large-area power-cuts, its turn(a)round, is typically also required to half a year
Left and right.Accordingly, because the expensive cost of power transformer self and its critical role in power system, it has an accident
The direct indirect loss brought will be the hugest.
Summary of the invention
In view of this, it is contemplated that propose a kind of device detecting oil-filled transformer insulation ag(e)ing, it is possible to supervise in real time
Ageing products content parameter during control insulating paper, and can the data of remote transmission ageing information, remotely obtain for user
Take and monitor the ruuning situation of transformator, contribute to assessment and predict main degree of aging, facilitating timely MP maintenance prevention.
For reaching above-mentioned purpose, the technical scheme is that and be achieved in that:
A kind of device detecting oil-filled transformer insulation ag(e)ing, passes including the moisture being arranged within oil-filled transformer
Sensor, CO sensor, CO2Sensor, H2Sensor, furfural sensor and the first wireless communication unit, also include being arranged on described
The second wireless communication unit on oil-filled transformer shell body, main process chip module, wireless communication module, and be arranged on
The host computer of remote control terminal and alarm；Described moisture transducer, described CO sensor, described CO2Sensor, described H2Pass
Sensor, described furfural sensor are connected respectively to described first wireless communication unit, described first wireless communication unit and described
Second wireless communication unit radio communication connects, and described second wireless communication unit also accesses described main process chip module, institute
Stating the wireless communication module communication interface also with described main process chip module to be connected, described wireless communication module radio communication is even
Connecing described host computer, the control of described host computer is terminated with described alarm.
Further, described first wireless communication unit and described second wireless communication unit are all zigbee radio communication
Module.
Further, described wireless communication module is GPRS communication module.
Further, described alarm is audible-visual annunciator.
Relative to prior art, the device of detection oil-filled transformer insulation ag(e)ing of the present invention has following excellent
Gesture:
During insulating paper, its degree of polymerization and tensile strength will be gradually lowered, and generate moisture, CO, CO2、H2, and
The feature ageing products such as furfural, thus reduce specific insulation and tensile strength, cause dielectric loss to increase.In real work,
It is irreversible that solid paper insulation is occurred aging, can directly affect machinery and and the operation of electrical strength, the present invention's
Moisture transducer, CO sensor, CO2Sensor, H2Sensor and furfural sensor, it is possible to monitoring gathers in oil-filled transformer
The ageing products content of insulating paper, such as moisture, CO, CO2、H2And furfural content, and can be by with the second wireless communication unit even
The ageing parameter data monitored are transferred to main process chip module by the first wireless communication unit connect, then by with main place
The reason wireless communication module that connects soon of chip dies transfers data to host computer, for user's real time inspection, carries out aging monitoring, and one
Denier finds that degree of aging affects transformator and normally works, it is possible to the very first time keeps in repair.
