Description
Technical field
The utility model relates to the high-tension apparatus in a kind of power industry power plant and transformer station, is a kind of outdoor framework type isolating switch specifically.
Background technology
High voltage isolator is a kind of device for switching relatively simple for structure, one of device for switching important in power plant and transformer station's electrical system, its main application is the safety of work when ensureing maintenance, between the part that high voltage isolator is arranged on needs maintenance and other live part.Enough large obvious visible air insulation interval is formed with isolating switch.High voltage isolator only can be used for some handover operation not producing powerful electric arc, that is to say that it does not have arc-suppression function; High voltage isolator is divided into according to the difference of infield, indoor formula, outdoor type; Be divided into by insulation column number, open side type, queen post and three pillar type, each electric pressure has optional equipment.
Outdoor framework type high-voltage switch gear is the high-voltage switch gear for aerial cabling, topmost part is exactly dynamic and static contact, stationary contact connection bus, moving contact end connection line or equipment, the dynamic and static contact of isolating switch is all aloft, fixed contact is fixed on support, by changing the position of aerial moving contact, making it be separated with fixed contact, reaching the object of open-circuit line, because the position of high voltage isolator is higher, the aerial dynamic/static contact of manual operation is very inconvenient.Thus, people propose the scheme of some transmissions, total because too complicated, or cost is too high or often operate malfunctioning or not high because of coefficient of safety, and practicality is not strong in a word.
Utility model content
The technical problems to be solved in the utility model is to provide outdoor framework type single busbar connection isolating switch, can disconnecting switch operation simply and effectively, and device is reliable and stable, guarantees personal safety, and improves the coefficient of safety of power transformation operation equipment.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Outdoor framework type single busbar connection isolating switch, comprise support, moving contact, the fixed contact be fixed on support, comprise the transmission mechanism of the pull bar composition primarily of trunnion axis, connecting lever, vertically setting, hinged by lockweight between pull bar and connecting lever, weld between connecting lever with trunnion axis, the other end of trunnion axis is connected with moving contact; Position corresponding with pull bar on support is provided with retaining ring, and described pull bar is through in retaining ring.
Further improvement of the utility model is: retaining ring is welded on a retaining ring frame be arranged in parallel with pull bar, and the upper and lower of retaining ring frame welds the retaining ring that is entangled pull bar respectively, bottom retaining ring is provided with the insulating cord of binding pull bar bottom.
Owing to adopting technique scheme, the technological progress acquired by the utility model is:
The utility model can disconnecting switch operation simply and effectively, and device is reliable and stable, guarantees personal safety, and improves the coefficient of safety of power transformation operation equipment.
Transmission mechanism mainly comprises pull bar, connecting lever, trunnion axis, is flexibly connected between pull bar with connecting lever by lockweight, welds between connecting lever with trunnion axis, and the other end of trunnion axis is connected with moving contact; Pull bar moves downward, and change angle with the connecting lever of pull bar pin joint, one end that connecting lever welds with trunnion axis upwarps, and drive trunnion axis to upwarp, moving contact is separated with fixed contact.Ensuring smooth transmission, reduces transmission error.People can complete the conjunction of aerial isolating switch, disconnected operation on ground by less power.
No matter be hinged or welding, along with the time is elongated, all likely occur the situation that contact point is aging or loosening; and pull bar is usually very long; go wrong once connect, pull bar is as easy as rolling off a log to fall, when pull bar falls; support is provided with retaining ring; pull bar is through in retaining ring, and the protection of retaining ring makes pull bar remain on original position, makes it not fall; avoid it to pound peripherad staff or high-tension apparatus, cause electric power safety accident.
Retaining ring is welded on retaining ring frame, retaining ring frame is parallel with pull bar, the upper and lower of retaining ring frame welds the retaining ring that is entangled pull bar respectively, bottom retaining ring is provided with the insulating cord of binding pull bar bottom, after combined floodgate, with insulating cord, pull bar is pinioned, pull bar is not rocked, pulling function is not produced to moving contact, reduce the line powering problem due to the bad generation of dynamic and static contact, by minimum for may dropping to of misoperation.
Because support is the device providing firm supporting function to high-tension line entirety, so support has stable, that spatial distribution is wide feature, retaining ring is welded on retaining ring frame, retaining ring frame is connected on the support of pull bar, or retaining ring is directly connected on support, it is convenient to implement, and connects reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 1, pull bar; 2, connecting lever; 3, trunnion axis; 4, retaining ring; 5, fixed contact; 6, retaining ring frame; 7, support; 8, moving contact.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details:
Outdoor framework type single busbar connection isolating switch, comprise support 7, moving contact 8, fixed contact 5, transmission mechanism, transmission mechanism forms primarily of pull bar 1, connecting lever 2, trunnion axis 3, pull bar 1 is vertically arranged, and from the isolating switch of the high-voltage line of aerial cabling, fixed contact 5 and moving contact 8 are all aloft, this just needs staff or work high above the ground, or changed the position of skyborne moving contact 8 on ground by certain way, make it be separated with fixed contact 5, with this open-circuit line.Hinged by lockweight between pull bar 1 and connecting lever 2, weld between connecting lever 2 with trunnion axis 3, the other end of trunnion axis 3 is connected with moving contact 8; Pull bar 1 moves downward, and the connecting lever 2 hinged with pull bar 1 changes angle, and one end that connecting lever 2 welds with trunnion axis 3 upwarps, and drive trunnion axis 3 to upwarp, moving contact 8 is separated with fixed contact 5.But no matter be hinged or welding, along with the time is elongated, all likely there is the situation that tie point is aging or loosening, go wrong once connect, add pull bar 1 and usually need several meters even longer, pull bar 1 is as easy as rolling off a log to fall, and around pull bar 1, often there is other switches or circuit, pull bar 1 pounds facility or staff towards periphery, and consequence is hardly imaginable.Be through in retaining ring 4 so arrange pull bar 1, retaining ring 4 is arranged on position corresponding with pull bar 1 on support 7, has had the protection of retaining ring 4, even if the connection of transmission mechanism goes wrong, pull bar 1 has the danger fallen, and also can stop the possibility fallen; Or retaining ring 4 welds on retaining ring frame 6, retaining ring frame 6 is parallel with pull bar 1, the upper and lower of retaining ring frame 6 welds the retaining ring 4 that is entangled pull bar 1 respectively, bottom retaining ring 4 is provided with the insulating cord of binding pull bar 1 bottom, after combined floodgate, with insulating cord, pull bar 1 is pinioned, make it not rock, pulling function is not produced to moving contact 8.Ensure the normal operation of the personal safety of staff, high-tension apparatus and circuit.
