Embodiment
Below with reference to specific embodiment and Figure of description the utility model is described in further details.
As Fig. 1, Fig. 2 and shown in Figure 3, the intelligent deicing device of the utility model substation bus bar portal frame, comprise heating Based Intelligent Control assembly 4 and the more than one eddy current heating component of arranging along portal frame steel pipe 51, utilize the metal heat-conducting and the eddy current heating principle of portal frame, realize efficiently heating.Eddy current heating component 1 comprises the iron collar 101 that is clamped on portal frame steel pipe 5 outer walls; be provided with the insulation collar 102 between the iron collar 101 and the portal frame steel pipe 5; be filled with insulation filler 104 in the insulation collar 102; be arranged with hot-wire coil 103 on the insulation collar 102; hot-wire coil 103 links to each other with heating Based Intelligent Control assembly 4 by control line; and link to each other with heating power supply 105 by power line 106, power line 106 of the present utility model and control line are all protected with unusual casing.Under the control of heating Based Intelligent Control assembly 4, eddy current heating component 1 starts, and portal frame steel pipe 5 is heated prevention or removal icing.Adopt high-performance eddy current mode of heating during eddy current heating component 1 ice-melt of the present utility model, thus evolution of heat dissolving icing.
The temperature detection sensory package 3 that heating Based Intelligent Control assembly 4 and is used for detecting external environment condition and portal frame temperature links to each other, after this temperature detection sensory package 3 detects ambient temperature, judges whether to heat by heating Based Intelligent Control assembly 4.If under the temperature that ambient temperature is set in heating Based Intelligent Control assembly 4, heating Based Intelligent Control assembly 4 will send the heating instruction to eddy current heating component 1, and eddy current heating component 1 will heat portal frame steel pipe 5, and preventing freezing is removed icing.In the present embodiment, the sensing probe of temperature detection sensory package 3 is installed in the sleeve of eddy current heating component 1, and is close to the metallic object of portal frame.
In preferred embodiment, heating Based Intelligent Control assembly 4 also can be further links to each other with the icing pull sensing assembly 2 that is used for detecting portal frame steel pipe 5 force-bearing situations, in case when icing occurring on the portal frame steel pipe 5, the deadweight of portal frame steel pipe 5 will increase, and portal frame steel pipe 5 will produce pulling force to the portal frame at two ends.If icing pull sensing assembly 2 detected pulling force surpass the value of thrust of setting in heating Based Intelligent Control assembly 4, heating Based Intelligent Control assembly 4 will send the heating instruction to eddy current heating component 1, eddy current heating component 1 will heat portal frame steel pipe 5, remove icing.
Heating Based Intelligent Control assembly 4 also can be simultaneously judges whether to heat in conjunction with the integrated data of temperature detection sensory package 3 and icing pull sensing assembly 2, promptly, the ice covering thickness overrate bears pulling force on the portal frame steel pipe 5 greater than heating maximum default in the Based Intelligent Control assembly 4 when causing, and when ambient temperature was lower than in the heating Based Intelligent Control assembly 4 preset temperature, eddy current heating component 1 moved automatically; When ice covering thickness was higher than preset value or portal frame temperature and is higher than preset value, eddy current heating component 1 stopped heating.For example, referring to Fig. 2, icing pull sensing assembly 2 adopts normally closed type pulling force controlled switch, switch closure when the detection pulling force is excessive, and a level temperature detection sensory package 3 send backward; Temperature detection sensory package 3 adopts normally closed type controlled temperature switch, switch disconnects when the detected temperatures value reaches capping value (20 ℃), switch closure when detected temperatures is lower than the lower limit (0 ℃) of setting, thus realize when pulling force and temperature data is all satisfied when adding condition that eddy current heating component 1 just can obtain working power.
The above only is a preferred implementation of the present utility model, and protection range of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection range of the present utility model.Should be pointed out that for those skilled in the art in the some improvements and modifications that do not break away under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
