Description
Technical field
The present invention relates to a kind of shelf depreciation wireless monitor system based on ultrasound wave.
Background technology
Along with advancing by leaps and bounds of China's power industry, modern power systems forward bulk power grid, large-sized unit, supertension,
Jumbo direction is developed, and the dielectric level of power equipment be it is also proposed requirements at the higher level.Transformer and distribution power station is as intelligence
Its all kinds of electrical equipments are implemented insulation state monitoring and carry out in early days by grid power transmission, the important step of distribution system
Early warning, can be effectively improved the operational reliability of transformer and distribution power station electrical equipment, reduces the operation expense of equipment,
In the service life of extension device, reduce accident rate.
Shelf depreciation is one of significant data of reflection transformer and distribution power station key equipment insulating properties, contains apparatus insulated
The sign of deterioration and the form of expression, it is possible to reflection inside electric appliance operating condition and state of insulation in advance, send out in time
Existing device interior insulation potential safety hazard that may be present or defect, it is simple to staff takes to process targetedly to arrange
Execute, prevent latency, the generation of sudden severe accident.Therefore, partial discharge monitoring is as the weight of insulation diagnosis
Want means to obtain increasingly to be widely applied.
The monitoring method of shelf depreciation mainly has chemical monitoring method, pulse current method, ultrahigh frequency monitoring method, surpasses at present
Sound wave monitoring method etc..
Chemical monitoring method: during shelf depreciation, insulant can be resolved into variety classes by under the effect such as hot, electric
Gas, can be judged, such as gas chromatography by the concentration of detection gas with various.But such method timeliness is relatively
Difference, responding ability is not enough.
Pulse current method: detect transformer by detection impedance, close capacitor, sleeve pipe, transformator and consolidate
The shelf depreciation of body insulation system etc..Its detection information coverage rate is not complete, quantity of information is less, and easily receives existing
The interference of the various conditions in field.
Ultrahigh frequency monitoring method: produced hyperfrequency (300-3000MHz) signal of telecommunication during detection shelf depreciation.Should
There are some inherent defects in method: to certain class only with the partial discharge monitoring weak effect of below 300MHz electromagnetic wave；
Signal is the strongest etc. by decay when propagating in insulating oil of sleeve pipe or distance.
Monitoring ultrasonic method: the ultrasound wave produced when receiving electrical equipment generation shelf depreciation with ultrasonic sensor,
Thus detect the size and location of shelf depreciation.The method does not has any impact to the operation of equipment, is more suitable for
On-line monitoring, has original advantage in terms of equipment discharge source location simultaneously.
In high voltage variable power distribution station, electrical equipment is numerous, and current partial discharge detection exists maximum problem two aspects: lack
Weary effective insulated on-line monitoring method and data transmission difficulty are big.
Monitoring system is limited by sensor operating mode etc., and how for a certain particular device, such as GIS device is monitored, opened
Close cabinet equipment monitoring etc., it is difficult to cover all critical electrical equipment of transformer and distribution power station, to the timely prison of operations staff
Survey is made troubles.
Transformer and distribution power station actual condition is complicated, and equipment under test is numerous, needs substantial amounts of data transmission link.Use wired
Data transmission is difficult to the communication requirement meeting between monitoring terminal and industrial computer.
Monitoring system lacks the rationally storage to historical data and management.The insulation defect of electrical equipment is different from other
Fault, is not the wink property sent out fault, mostly is the result that long time integration produces.Historical data is to judging exactly to set
Standby hidden danger also takes specific aim measure significant, and this just stores the data of monitoring system and administrative mechanism carries
Go out very high request.
