Description
Technical field
The utility model relates to the high voltage drop-out type fuse cutout on a kind of electrical network, particularly about a kind of wireless remote control fuse switch.The utility model is applicable to the on high-tension side protection switch of power transformer.
Background technology
Between the high-tension line of electric power network and transformer, high voltage drop-out type fuse cutout is housed all, the needs of being convenient to transformer equipment and line upkeep maintenance or rationing the power supply.Common high voltage drop-out type fuse cutout, generally form by high-tension porcelain insulator, fuse tube, high-voltage switch gear wiring, when separating brake or combined floodgate, needs use special high-pressure insulating rod is manually pushed to or is left behind, operating personnel need dress insulation boots and insulating gloves during work, operate cumbersomely, and security incident takes place easily.For this reason, the Chinese patent publication number is wireless remote control and the manual dual-purpose fuse switch of CN2456308, can pass through remote controller, control motor forward or reverse, the separating brake or the combined floodgate of realization fuse, easy to operate, safety.But, the high voltage drop-out type fuse cutout of existing various versions, anyone can leave behind fuse tube with the High-Voltage Insulation rod or close at any time, causes frequent generation illegally to be operated a switch and steals transformer equipment phenomenon and the illegal power stealing phenomenon of closing a floodgate.
Summary of the invention
The purpose of this utility model is the deficiency that exists at prior art, provides a kind of and can lock fuse tube, makes the non-electricity administrative staff can not arbitrarily operate the wireless remote control device fuse switch with lock of fuse tube folding condition.
The technical scheme that realizes the utility model purpose comprises high-tension porcelain insulator, fuse tube and supporting device thereof, high-voltage switch gear binding post and installed part, high-tension porcelain insulator is installed on the mounting panel, the fuse tube upper end is connected with upper connecting terminal by upper contact head, the lower end is being supported by its supporting device, and be connected with lower connecting terminal, mainly be that the fuse tube upper end is provided with locking device, this locking device is by tapered end, jointed gear unit, drive motors and motor remote control are formed, drive motors is installed on the mounting panel, one end of jointed gear unit is connected with the rotating shaft of drive motors, and the other end is connected with tapered end.
In above technical scheme, tapered end is made up of hammerlock and latch hook, and hammerlock is terminal to be connected with jointed gear unit.
In above technical scheme, the latch hook end is shaped on crotch, and at the crotch upside spring is set, and this crotch is at the groove location place between fuse tube and its upper end copper contact under the tapered end locking state, and spring contacts on copper contact.
The utility model advantage compared with prior art is: be provided with a locking device by remote controller control in the fuse tube upper end, when fuse tube is under the "on" position locking device locking, tapered end hooks fuse tube upper end copper contact, can not manually operate a switch, prevent from illegally to operate a switch and steal the generation of transformer equipment; When fuse tube was under the state of opening a sluice gate the locking device locking, tapered end blocked upper contact head, and fuse tube can not be closed a floodgate, and preventing the illegal power stealing of closing a floodgate; When locking device when locking under the fuse tube blown state, the fuse tube tapered end below that drops can be fallen automatically, does not influence the normal function of use of fuse switch.

Embodiment
The device fuse switch with lock of wireless remote control as shown in Figure 1 and Figure 2 comprises high-tension porcelain insulator 9, fuse tube 6 and supporting device 7 thereof, high-voltage switch gear terminals and installed part.The high-voltage switch gear terminals are by upper connecting terminal 10 and lower connecting terminal 11, upper connecting terminal 10 is fixedly mounted on the upper end of high-tension porcelain insulator 9, be connected with the electrical network high-voltage line, lower connecting terminal 11 is fixedly mounted on the lower end of high-tension porcelain insulator 9, is connected with the transformer high-voltage lateral coil.High-tension porcelain insulator 9 is installed on the mounting panel 12, and fuse tube 6 upper ends are connected with upper connecting terminal 10 by upper contact head, and the lower end is being supported by its supporting device 7, and is connected with lower connecting terminal 11.Upper end at fuse tube 6 is provided with locking device, and this locking device is made up of tapered end, jointed gear unit, drive motors 8 and motor remote control.Drive motors 8 is installed on the mounting panel 12, and an end of jointed gear unit is connected with the rotating shaft of drive motors 8, and the other end is connected with tapered end.Jointed gear unit is made up of pull bar 3 and pivoted arm 13, pull bar 3 adopts insulating material, and the one end is connected transmission with the rotating shaft screw-and-nut of drive motors 8, and the other end and pivoted arm 13 are hinged, when drive motors 8 rotations, drive pull bar 3 and make tapered end lock or upwards open downwards.Tapered end is made up of hammerlock 2 and latch hook 15, and hammerlock 2 ends are movably connected on the installing rack 14, can rotate at last installing rack 14, fixedlys connected with the pivoted arm 13 of jointed gear unit simultaneously.
In above embodiment, latch hook 15 ends are shaped on crotch 5, and at crotch 5 upsides spring 1 are set, and this crotch 5 is at the groove location place between fuse tube 6 and its upper end copper contact under the tapered end locking state, and spring 1 contacts on copper contact.When manually operating a switch, the crotch 5 of latch hook 15 ends just in time embeds in the groove between the copper contact of fuse tube 6 and its upper end, prevents that fuse tube 6 from operating a switch.After the fusible link of fuse tube 6 fuses because of excess load, fuse tube 6 free falls, spring 1 contacts on copper contact, prevents to guarantee that fuse tube 6 free falls fall in the groove between crotch 5 embedding fuse tubes 6 and its upper end copper contact.
In the above-described embodiments, tapered end, installing rack 14 adopt insulating material, also can adopt metal material.
In the above-described embodiments, fuse tube 6 can be by manual mode separating brake or combined floodgate, also can be by wireless remote control mode separating brake or combined floodgate, and can also be by Long-distance Control mode separating brake or combined floodgate.
Operation principle: fuse tube 6 is opened tapered end by remote controller controlling and driving motor 8 earlier before separating brake or closing operation, and at fuse tube 6 at separating brake or after closing a floodgate, by remote controller controlling and driving motor 8 tapered end is locked.After fuse tube 6 closes a floodgate, 8 rotations of remote controller controlling and driving motor, transmission pull bar 3, pivoted arm 13 are locked hammerlock 2 and latch hook 15 thereof downwards, and at this moment, latch hook 15 retainings prevent that fuse tube 6 from illegally being operated a switch, and make the transformer outage stolen in fuse tube 6 outsides; When fuse tube 6 needed separating brake, at first by remote controller controlling and driving motor 8 rotation, transmission pull bar 3, pivoted arm 13 upwardly opened hammerlock 2 and latch hook 15 thereof, opened fuse tube 6 separating brakes by manual, wireless remote control or Long-distance Control mode then; Behind fuse tube 6 separating brakes, 8 rotations of remote controller controlling and driving motor, transmission pull bar 3, pivoted arm 13 are locked hammerlock 2 and latch hook 15 thereof downwards, and at this moment, fuse tube 6 will be blocked and can not close a floodgate by latch hook 15, prevent the illegal power stealing of closing a floodgate; After the fusible link of fuse tube 6 is because of excess load fusing, fuse tube 6 free falls to latch hook 15 with upper/lower positions, and automatic brake separating, the excess load that does not influence fuse is opened a sluice gate function automatically.
