The mounting base 23 is provided with mounting holes, the mounting base 23 is used for being mounted on a tower near a wire to be subjected to icing detection, and the power supply device 10 is used for supplying power to power consumption components.
It should be noted that, in the present application, the detection module is actually a data processor, which is used to implement signal processing, and the detection module only needs to be a data processor in the prior art, which is not described here again.
The power supply device 10 is a solar power supply device, and the solar power supply device is installed on a tower or a chassis 22.
In this embodiment, the icing sensor is an optical fiber icing sensor.
The weight sensor in this embodiment is in particular a load cell.
The storage battery connected with the solar power supply device is arranged in the case 22, so that electric energy is stored.
In actual use, the utility model is arranged on a pole tower near a lead to enable the pole tower to be in the same icing environment, so that the icing condition of the lead and the detecting rod 21 is approximately the same, when the weighing sensor detects that the weight on the detecting rod 21 changes, the optical fiber icing sensor firstly detects whether an icing signal is generated, interference is eliminated, after the icing signal is determined, the weighing sensor weighs out the icing weight on the detecting rod 21, icing data processing is carried out through a detecting module in the icing machine box 22, icing information on the lead is indirectly obtained, and the icing condition on the detecting rod 21 can reflect the icing condition of the lead because the environments are similar; the detection module uses big dipper wireless transmission to icing monitoring station through big dipper signal transmission module with the icing information on the wire that detects, and solar power supply unit 10 can be for big dipper signal transmission module, detection module, icing sensor, power consumption parts such as weight sensor supply power. In actual use, only the detection rod 21 is required to be monitored, and the icing information of the lead under similar environmental conditions can be obtained, so that real-time online automatic indirect icing detection is realized, and the staff can conveniently take corresponding deicing measures.
In order to facilitate a further understanding of the utility model by those skilled in the art, the utility model is further described below in connection with specific language.
Fig. 3, tower0 is a tower of the present utility model, and is used for installing the indirect icing detection device for transmission line of the present utility model.
In the figure, lx1 and Lx2 are the lengths (meters) of wires erected by adjacent towers;
dx1 and Dx2 are horizontal distances (meters) between adjacent towers;
hx1 and Hx2 are vertical distances (meters) between adjacent towers;
When the weighing sensor detects that the weight on the icing detection rod 21 changes, and the optical fiber icing sensor arranged in the icing detection rod 21 does not detect an effective icing electric signal, the optical fiber icing sensor judges that the optical fiber icing sensor is an interference signal and does not process icing data;
When the optical fiber type icing sensor arranged in the icing detection rod 21 detects effective icing electric signals, after the icing electric signals are determined, the weighing sensor can detect icing weight ρs of a unit length on the icing detection rod 21;
The specific data processing is as follows:
The tension Fx born by the two ends of the wire (the contact points with the iron tower) can be calculated through a suspension formula by on-site wire installation, and is the maximum tension point born by the wire, and the tension is determined by the following parameters:
(1) Weight ρlx (kg/m) of power transmission wire per unit length
(2) Icing weight ρice (kg/m) of a power transmission line per unit length
(3) Lx length of wire (meter) erected on adjacent iron tower
(4) Dx horizontal distance (meters) between adjacent towers
(5) Hx: vertical distance (meter) between adjacent towers
Fx=f (Lx, dx, hx, plx+alice), where f is the suspension formula.
Wherein, the icing weight ρice of the power transmission line per unit length and the icing weight ρs of the icing detector 20 can be equivalently calculated by the following formula;
ρice＝ρs*(RLx/Rs)*0.93；
ρs: the icing weight detected by the icing detector 20;
RLx: the diameter of the transmission wire;
Rs: the diameter of the icing detection rod 21;
In actual use, rs can be designed to be consistent with RLx, so that the precision is improved. The more severe the icing, the greater the ρice, the greater the tension the wire is subjected to, and after reaching the limits of the wire, the wire may break or the tower may collapse.
Through the data processing, the icing information on the wire is obtained, and the detected icing information on the wire is transmitted to the icing monitoring station by the Beidou wireless transmission module, so that real-time online automatic indirect icing detection is realized.
Example two
The present embodiment is further optimized based on the first embodiment, in which a heating device is disposed in the detecting rod 21, and the heating device is connected to the detecting module and the power supply device 10 through a switch.
Wherein the heating device is a heating rod or a heating wire arranged in the detection rod 21.
Thus, in actual use, when the icing on the detection rod 21 reaches the preset upper limit, the heating device can be started to melt the ice on the detection rod 21, so that the accuracy of the weight sensor is prevented from being influenced by the overweight of the icing.
While preferred embodiments of the present utility model have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. It is therefore intended that the following claims be interpreted as including the preferred embodiments and all such alterations and modifications as fall within the scope of the utility model.
