Abstract
The invention belongs to the field of power transmission line devices, and especially relates to a disconnecting switch with a protective sleeve isolation plate. The disconnecting switch comprises a pedestal, and the pedestal is provided with an insulating column. The insulating column is provided with a knife switch, and two ends of the knife switch are provided with binding posts. The external surface of each binding post is provided with a protection sleeve in a sleeving manner, and the protection sleeves are provided with rotating sleeves. The external peripheral surface of each protection sleeve is provided with a positioning backing pin, wherein the positioning backing pin prevents the corresponding protection sleeve from sliding axially. The protection sleeve at one side is provided with an annular groove, and the rotating sleeve located in the same vertical plane as the groove is provided with a through hole. The interior of the through hole is provided with a positioning rod, wherein one end of the positioning rod stretches out of the corresponding rotating sleeve, and the other end of the positioning rod is provided with a positioning head which can stretch out and draw back along the axis of the positioning rod. The tail of the positioning head is disposed in the positioning rod, and the head of the positioning head extends into the groove. The external peripheral surface of each rotating sleeve is provided with a pull ring. An arc-shaped isolation plate is disposed between the protection sleeves at two ends of the knife switch. The device can reduce the probability that an insulating blanket is broken down by arcs, and protects the safety of a line worker.
Description
Technical field

The high-tension electricity of high voltage transmission line needs to enter transformer, resident and factory's use could be supplied after voltage drop being got off, isolating switch is provided with between high-tension line and transformer, with easy to maintenance after ensureing, usual isolating switch and transformer are arranged on same single line bar, these line bars are arranged on field usually, so the safety in order to ensure circuit, need regularly to clear up the bird's nest on line bar, because present bird is when building bird's nest, employ the raw material of some Metallic rod, so cleaning Bird's Nest need with insulated target, isolating switch is covered, prevent Metallic rod from dropping near isolating switch, be communicated with not homophase, cause short circuit, although insulated target can play certain protective effect, but insulated target is also have the situation by punching to occur, insulated target is once breakdown, in order to ensure the safety of electric operating personnel, just can not re-use, and the price of a bar insulation blanket is in thousands of unit, therefore, easily cause the waste of resource.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art and a kind of isolating switch with protective sleeve dividing plate invented.
The present invention is achieved in that a kind of isolating switch with protective sleeve dividing plate, comprise base, the two ends, left and right of base are respectively arranged with insulated column, plug-in strip is provided with between insulated column, the two ends of plug-in strip are provided with binding post, it is characterized in that: the binding post outer surface of plug-in strip both sides is all set with protective sleeve, described protective sleeve is cylindrical away from a section of plug-in strip, protective sleeve is rectangle near the cross section of plug-in strip one section, the described periphery being positioned at cylindrical protective cover is set with columned rotary sleeve, space is provided with between the inner headed face of rotary sleeve and the periphery of protective sleeve, the periphery of protective sleeve is arranged location backing pin, location backing pin prevents protective sleeve from axially sliding, the protective sleeve of side is provided with a circle groove, the rotary sleeve being positioned at same vertical plane with groove is provided with a through hole, backstay is provided with in through hole, one end of described backstay reaches the outside of rotary sleeve, the other end of backstay is provided with the positioning head that can stretch up and down along backstay axis, the afterbody of described positioning head is sleeved in backstay, the head of positioning head extend in groove, positioning head can slide in adjacent groove under the effect of external force in of a protective sleeve groove, the periphery of described rotary sleeve is also provided with draw ring, the dividing plate of arc-shaped is provided with between the protective sleeve at plug-in strip two ends, plug-in strip is positioned at the side inside, two, left and right of dividing plate.
Further, described draw ring comprises tab lever and is arranged on tab lever top draw ring head, and tab lever is arranged in rotary sleeve.
Further, the cross sectional shape being positioned at vertical plane of described groove is isosceles trapezoid or isosceles triangle.
Further, described backstay one end is provided with cavity, the head of positioning head is sleeved in cavity, spring is provided with between this end positioning head end and cavity top, spring is in compressive state, and the cross sectional shape that the afterbody of positioning head is positioned at vertical plane is isosceles trapezoid, isosceles triangle or circular arc.
Further, the radian of the dividing plate of described arc-shaped is greater than 0 ° and is less than 90 °.
Further, described dividing plate side is provided with there is flexible soft limit.
The present invention has the following advantages:
Dividing plate is positioned at above plug-in strip, and when overhauling circuit, insulated target on dividing plate covers, can reduce insulated target greatly by the probability of arc through.In addition when needs disconnect plug-in strip time, staff's hand or catch on draw ring with hook, rotate rotary sleeve, the positioning head of backstay bottom enters into another groove from a groove, thus plug-in strip is not covered by dividing plate, when find need to close time, drag hook hand or catch on draw ring with hook, counter-rotation rotary sleeve; Preferred dividing plate side is provided with there is flexible soft limit, after soft limit touches insulated column, deformation occurs, dividing plate can being made to continue to rotate, with leaving larger space above plug-in strip, decreasing the interference between dividing plate and insulated column.
