1, according to the setting of different icing situation with select the segmentation ice-melt automatically.
2, avoid common ice-melt completely to cause the waste of the energy.
Description of drawings
Below will combine accompanying drawing that the specific embodiment of the utility model is described in further detail, wherein:
Fig. 1 is the principle schematic of the utility model power transmission line deicing device embodiment 1.
Embodiment
Embodiment 1
Power transmission line deicing device as shown in Figure 1; Comprise compound wire, combination switch and composite control apparatus, said compound wire is formed by split conductor 1 and nuditing wire 2 seals strand system, and wherein insulated conductor 1 is positioned at internal layer; Nuditing wire 2 is positioned at skin; Said combination switch comprises and cut-offs part and can not cut-off part, can cut-off partially enclosedly in switch case, wherein can cut-off the part and insulated conductor 1 electric connection of compound wire; Can not cut-off part connects with nuditing wire 2 electricity; Said composite control apparatus stresses device by icing and temperature control equipment is formed, and said icing stresses device and has a pair of icing check weighing contact 3, and said temperature control equipment has couple of conductor temperature contact 4.Said switch can cut-off part by solenoid 5 actuating separating brakes, and spring 6 actuatings are closed a floodgate, compression switching-in spring energy storage during separating brake, and separating brake solenoid 5 provides electric current by current transformer 7 secondary sides that are located on the switch, and its loop is controlled by composite control apparatus.Connecting with current transformer 7 secondary coils and separating brake solenoid 5 with conductor temperature contact 4 successively in said icing check weighing contact 3 is a loop, wherein arbitrary to or two pairs of electric contacts all be disconnected in separating brake solenoid 5 loops when all being in off-state.
Operation principle is following: combination switch can cut-off part and pass through spring promotion maintenance "on" position, and the compound wire total cross-section is long-pending to be connected, the double ice melting operation of circuit.When two pairs of electric contacts were all connected, separating brake solenoid loop side connected, and combination switch can be cut-off part break off, and the insulated conductor loop that connects in the compound wire is on it broken off, and only the reserve part sectional area is connected current-carrying, the double simultaneously ice melting operation of circuit on-load.After ice-melt was accomplished, conductor temperature contact and icing were surveyed electric contact and are broken off or break off simultaneously, and separating brake solenoid loop all is disconnected and dead electricity, and switching-in spring promotion combination switch can cut-off part to be connected, and compound wire recovers the long-pending on-state of total cross-section.
It will be recognized by those skilled in the art, under the prerequisite that does not depart from protection scope of the present invention, can carry out various modifications, variation and combination, and think that this modification, variation and combination are within the scope of originality thought above-mentioned execution mode.
