Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the invention will be further described.
As accompanying drawing 1, 2, 3, shown in 4, a kind of fault detector of distribution line, comprise shell 1 and lower casing 2, described upper shell 1 is built with upper core 5, gathering sill 6 is provided with in upper shell 1, retractor device is equiped with in gathering sill 6, this retractor device drives upper shell 1 to move up and down along gathering sill 6, lower casing 2 is built with mainboard 7 and the lower core 9 with inductive coil 8, the inductive coil 8 of lower core 9 is electrically connected with mainboard 7, lower casing 2 outside surface is equipped with supply unit 3, this supply unit 3 is electrically connected with mainboard 7, slot 10 is provided with in lower casing 2, the movable plug-in mounting of gathering sill 6 of upper shell 1 enters in slot 10.Mainboard 7 being equiped with Anneta module 14, mainboard 7 is also configured with wireless transmitter module etc., being transferred to monitoring center for managerial personnel's observation analysis for being sent by fault-signal.Described mainboard has logic judging function, and each arrangements of components on this mainboard is existing known technology, does not repeat at this to its detailed construction.Supply unit provides power supply for mainboard, can normally work.Supply unit 3 is preferably installed in the photovoltaic cell of lower casing outside surface, and this photovoltaic cell is connected with mainboard electricity 7 by circuitron 4, and namely circuitron 4 one end is connected with photovoltaic cell, and circuitron 4 other end is electrically connected with mainboard 7.In addition, photovoltaic cell can arrange four groups, or six groups, set flexibly according to actual needs.Circuitron 4 and lower casing 2 are formed in one structure.Retractor device comprises guide pole 11 and spring 12, and be contained in lower casing 2 inner bottom surface bottom guide pole 11, spring 12 is sleeved on guide pole 11.Lower casing 2 stretches into the stop 13 in slot 10 built with one end, gathering sill 6 bottom offers the screens 15 be convenient to stop 13 and blocked, and the gathering sill 6 of this stop 13 to upper shell 1 plays position-limiting action.In addition, upper core and lower core are all designed to semicircle, can match.
As shown in Figure 5, described stop 13 comprises housing 1301, Compress Spring 1302, connecting rod 1303, portable plate 1304 and spacing 1305, Compress Spring 1302, connecting rod 1303 and portable plate 1304 are all contained in housing 1301, Compress Spring 1302, connecting rod 1303 and portable plate 1304 are installed from left to right successively, spacing 1305 one end activities are contained in housing 1301, connecting rod 1303 one end is connected with Compress Spring 1302, this connecting rod 1303 other end is connected with portable plate 1304, and spacing 1305 clamps mutually with portable plate 1304.Portable plate 1304 moves along with the stretching of Compress Spring 1302 or compression, thus drives spacing 1305 to move.Spacing 1305 inwalls can offer stopper slot, and portable plate is provided with tooth, and this tooth moves and realizes engaging in stopper slot.
Principle of work of the present invention is set forth further below with each duty.
As shown in Figure 4,5, upper shell 1 coincide with lower casing 2, upper core 5 and lower core 9 is coincide into and forms a closed magnetic circuit mutually together.Spring 12 now on guide pole 11 is free state, and spacing 1305 of stop 13 is squeezed the middle and upper part lateral surface heading on shell 1 gathering sill 6.Now be subject to the extruding of shell 1 gathering sill 6 for spacing 1305, spacing 1305 Compressive activities plates 1304, portable plate 1304 extrudes connecting rod 1303, and connecting rod 1303 extrudes Compress Spring 1302, and Compress Spring 1302 is shunk.Now whole indicator is in closed running status.
As shown in Figure 6,7, upper shell 1 and lower casing 2 are in mutual open mode, and namely upper core 5 and lower core 9 form closed magnetic circuit together with coincideing.Because upper shell 1 moves up, make spring 12 in compressive state.Spacing 1305 of stop 13 is just positioned at screens 15 position of gathering sill 6.Be not subject to the extruding of shell 1 gathering sill 6 for spacing 1305, original Compress Spring 1302 in compressive state discharges elastic force, make connecting rod 1303 promote portable plate 1304 to move, thus promote spacing 1305 and move, make spacing 1305 screens 15 position being stuck in gathering sill 6.
As shown in Figure 8,9, for the present invention is by the schematic diagram opening stationary state and be returned to closure state.Under the effect of external force, upper shell 1 continues up to move, and spring 12 continues to be compressed.When upper shell 1 up moves a certain distance, spacing 1305 of stop 13 is subject to the extruding of screens 13 lower bevel of gathering sill 6, portable plate 1304 is subject to the extruding of spacing 1305, portable plate 1304 extrudes Compress Spring 1302, and this Compress Spring 1302 shrinks in the housing 1301 of stop 13 draws over to one's side.Now cancel External Force Acting, because the spring 12 of gathering sill 6 is in compressive state, this spring 12 retracting spring pressure, thus drive upper shell 1 to move down, the state until the spring 12 in gathering sill 6 affranchises, now upper core 5 and lower core 9 coincide again and form closed magnetic circuit, make indicator be in closure state, as shown in Figure 4.Stop by the screens position transfer of gathering sill to the middle and upper part of gathering sill.
