Description
Technical field
The utility model belongs to transmission line online monitoring field more particularly to a kind of transmission line of electricity equivalence ice covering thickness prison
Examining system.
Background technique
Anti-icing anti-ice is all the most important thing of Research Work of Power Transmission Line over the years, at present the monitoring of equivalent ice covering thickness both at home and abroad
Method is varied, including the equivalent diagnostic method of tilt-angle method, weight method, image, Meteorological Act etc..Widely used is weight method
With two kinds of tilt-angle method.But there is also certain defect and deficiency, main bodies for the equivalent ice covering thickness technology based on both methods
Present the following aspects:
The deficiency of weight method equivalence ice covering thickness monitoring technology has: one, being relatively specific for tangent tower, and be poorly suitable for resistance to
Tower: based on weight method be the vertical loads change in vertical span is monitored come indirect monitoring equivalence ice covering thickness this
Basic principle, unsuitable under strain insulator occasion to be monitored with weight method to ice covering thickness, this greatly affected icing
The alternative that monitoring device is layouted；Two, current insulator chain tension sensor is using to replace based on ball-eye
Mounting means, operating process complexity is cumbersome, is unfavorable for in-site installation and maintenance work；Three, the fitting type kind replaced is numerous
More, structure is different, and the model for resulting in insulator chain tension sensor is numerous, can not be interchangeable between each other；Four, it carries out
The replacement of line hardware increases hidden danger to the safe operation of route.
The deficiency of tilt-angle method equivalence ice covering thickness monitoring technology has: one, power system design existing defects: previous conducting wire
Inclination angle and the temperature sensor existing defects on taking energy mode, due to using conducting wire induction energy fetching mode, this takes can mode
The normal operation of lower sensor depend heavilys on the degree of stability (scope of application is small) of current in wire, therefore power-supply system runs one
Straight unstable, the failure rate of sensor can not have always been high any more.Two, the accuracy of monitoring data is poor: studies have shown that causing to monitor
The reason of poor accuracy, mainly there are three aspects: 1) conducting wire tilt-angle method needs high-precision conducting wire inclination angle monitoring sensor and props up
Support, class of accuracy need within 0.1 °；2) under strong wind operating condition, conducting wire is kept in motion, if only letter at this time
Single ground samples conducting wire inclination data, does not take filtering measure to noise caused by wind load, will greatly influence conducting wire
The accuracy of inclination angle monitoring, the final accuracy for influencing the monitoring of conducting wire equivalence ice covering thickness；3) do not fully consider that insulator chain inclines
The influence that oblique angle monitors icing, under icing operating condition, often there is different degrees of imbalance in suspension insulator two sides
Power, and icing is more serious, unbalanced tensile force difference is more significant, numerical simulation the result shows that, if ignored due to imbalance
The micro variation of conducting wire span caused by power, it will so that the stress of conductor and equivalent ice covering thickness that are finally calculated occur
Biggish error.
In conclusion power department needs a kind of accurate effective transmission line of electricity equivalence ice covering thickness monitoring system, come
Realize the monitoring of electric power line ice-covering thickness.
