Description
Technical field:
The present invention relates to the high-voltage switch gear technical field, exactly, it is a kind of closed outdoor high-voltage isolating switch.
Background technology:
Outdoor high-voltage isolating switch is one of electric equipment the most frequently used in the ultra-high-tension power transmission line.Thoroughly do away with the relative position of edge pillars on pedestal according to every phase two, high voltage isolator commonly used at present can be divided into two kinds on V-structure and erect type structure substantially.No matter be that V-type or its structure of erect type high voltage isolator are essentially identical, exactly every three bearing pedestals that two eradication edge pillars are housed mutually are installed in column and erect on the crossbeam of certain altitude, with crank, connecting rod insulation column and operating mechanism are linked together, constitute link gear; Pull operating mechanism, drive every two thoroughly doing away with the edge pillars and rotate in opposite directions mutually, realize the separation and the closure of insulation column top operator by connecting rod and crank.Also to increase by one group of ground cutter and linkage driving mechanism thereof when needing ground connection on the high voltage isolator.V-type high voltage isolator in using with present reality is example, and two thoroughly do away with on the bottom spindle nose of edge pillars a semi-circumference bevel gear is housed, and mesh together in bearing pedestal, drive bevel gear by operating mechanism, connecting rod, crank again and rotate in opposite directions.The bevel gear of total in bearing pedestal, outside parts such as connecting rod, crank, adjustment bolt all are exposed to, after erosion by wind and rain, parts corrosion, problems such as operating difficulties, service life of equipment shortening will appear; Particularly have method of operation improper slightly, the tooth phenomenon will appear taking off in this high voltage isolator that has the bevel gear transmission mechanism, brings a lot of inconvenience to use.
Aspect the high voltage isolator structural design, a lot of innovation and creation have appearred in recent years, as Chinese patent 03218090 disclosed anti-corrosion three high voltage isolator that links, be exactly on the original structure basis of high voltage isolator, after link gear improved, again link gear is done to form with sealing.Though it has solved the corrosion problem of link gear, the bevel gear drive mechanism expensive, easily take off tooth, be not easy to assembling and problems such as maintenance still exist.
Summary of the invention:
The present invention is that its purpose just provides a kind of simple in structure, and is with low cost to the technological improvement of existing high voltage isolator in configuration aspects, anti-corrosion, long service life, more easy to use, the assembling and the maintenance, be non-bevel geared closed outdoor high-voltage isolating switch especially.
The object of the present invention is achieved like this, and outdoor high-voltage isolating switch comprises operator and the operator linkage driving mechanism, insulation column, transmission case, cover body, column and the crossbeam that are made of operator operating mechanism, connecting rod, crank, connecting lever.Operator operating mechanism 1 utilizes support to be installed on the column 8, and links to each other with crank 12 by first connecting rod 11, and every phase two is thoroughly done away with edge pillar 31 and utilized bearing pedestal 4 to be installed on the transmission case 42.It is characterized in that: crossbeam 84 is installed on the pillar 8, transmission case 42 usefulness bolts 41 are fixed on the termination of crossbeam 84, cover body 5 spiral-locks are above crossbeam 84, two ends are fixed by bolts on the transmission case 42 at two ends, connecting lever 2 directly is fixed on the lower end of the insulation column main shaft 3 that is installed on the bearing pedestal 4, connecting rod the 2 22 two ends are hinged with crank 12 and threeway slide block 62 respectively, the other two ends and the third connecting rod 63 of threeway slide block 62 are hinged, the other end of third connecting rod 63 is hinged with the connecting lever 2 and the 4th connecting rod 23 that are fixed on the insulation column main shaft 3, the two ends of the 4th connecting rod 23 are again by adjusting bolt 25, the 5th connecting rod 21 and the 6th connecting rod 24 are hinged on the connecting lever on the other two-phase insulation column main shaft, constitute operator linkage driving mechanism.Roller 61 is housed below the threeway slide block 62, and pulley 61 is packed into and is fixed in the guide chute 6 on the crossbeam 84.When needs ground connection, configurable ground of the present invention cutter mechanism, the ground cutter mechanism comprises ground cutter fingertip, contact and by ground cutter operating mechanism, connecting rod, crank, the ground cutter linkage driving mechanism that connecting lever and push rod constitute, ground cutter operating mechanism 7 utilizes support to be installed on the column 8, and link to each other with crank 72 by seven-link assembly 71, ground connection fingertip 83 is fixed on the junction block 85, the 8th connecting rod 73 1 ends and crank 72 are hinged, the other end and connecting lever 75 and the 9th connecting rod 79 are hinged, the two ends of the 9th connecting rod 79 are again by adjusting bolt 76, the tenth connecting rod 77 and the 11 connecting rod 78 are hinged on the connecting lever of other two-phase ground cutter, the hinged push rod 74 of the other end of connecting lever 75, the ground connection cutter contact 81 that has connecting lever 82 is hinged on the transmission case 42.
Compared with prior art, the present invention has replaced the bevel gear transmission mechanism with the connecting lever transmission mechanism, has fundamentally avoided the generation of taking off the tooth phenomenon that causes because of misoperation; Make that also the version of operator linkage driving mechanism is more terse, equipment cost further reduces, and installs, debugs, uses more simple and convenient.The setting of guide chute, roller guiding mechanism, when making operator linkage driving mechanism kinematic very steadily, nimbly and freely.Independently cutter mechanism can be assembled up when needs ground connection at any time.Parts such as connecting rod, connecting lever, adjustment bolt prevent corrosion after zincizing is handled, can significantly be prolonged the useful life of equipment.In addition, three transmission cases among the present invention, two groups of crossbeams, two root posts and two sections cover bodies are for dividing body structure, and parts can be assembled after factory process at the construction field (site).
