Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Referring to Fig. 1 to Fig. 4, according to on-pole switch of the present invention, comprising: switch operation assembly and insulation shell 13, insulation shell 13 integral molded plastics are outside operating assembly.Insulation shell of the present invention all is cast in the switch operation assembly and realizes all insulation in the housing, does not re-use pernicious gas, and more environmental protection is safe and reliable.
Referring to Fig. 1 to Fig. 4, the switch operation assembly comprises quiet end conducting rod 1, vacuum interrupter 2 and moved end conducting rod 5, and vacuum interrupter 2 is arranged between quiet end conducting rod 1 and the moved end conducting rod 5.This on-pole switch prepare vacuum interrupter 2 and two ends conducting rod and moved end transmission component integral installation rear integrated poured in solid envelope body.
Referring to Fig. 1 to Fig. 4, on-pole switch also comprises the moved end transmission component, and the moved end transmission component is arranged between vacuum interrupter 2 and the moved end conducting rod 5.
Referring to Fig. 1 to Fig. 6, on-pole switch also comprises cast box 3, and cast box 3 is arranged on the below of moved end transmission component.Integrated poured in order to realize, need to form the protection chamber with a cast box at the transmission crank arm place.Cast box 3 is in order to fixed conveyor connecting lever 8, two in this effect one, is used for forming when a protection chamber makes cast expecting not enter the connecting lever cavity space, and the cast box is cast in the body and need not takes out after the cast.The suitable for reading outer large chamfering of doing of cast box 3, purpose are closely also to be conducive to withdrawing pattern in order better to fit with second half lid.
Referring to Fig. 1 to Fig. 4, the moved end transmission component comprise be flexible coupling 4, pull bar connecting stud 7, transmission crank arm 8 be connected guiding connecting lever 9 with the moved end, 4 deformable grounds that are flexible coupling are connected between vacuum interrupter 2 and the moved end conducting rod 5, transmission crank arm 8 is V-arrangement, and the two ends of transmission crank arm 8 are connected respectively guiding connecting lever 9 with the moved end and pull bar connecting stud 7 articulates.
Referring to Fig. 1 to Fig. 4, center and transmission crank arm 8 that the moved end connects guiding connecting lever 9 are articulated, and the end that the moved end connects guiding connecting lever 9 is connected with vacuum interrupter 2.Pull bar connecting stud 7 and transmission crank arm 8 articulate by the first connecting pin 6.Transmission crank arm 8 and cast box 3 articulate by the second connecting pin 10.The moved end connects guiding connecting lever 9 and articulates by the 3rd connecting pin 11 with cast box 3.
Referring to Fig. 1 to Fig. 2, the outboard end of quiet end conducting rod 1 and moved end conducting rod 5 is connected with sleeve pipe, on-pole switch comprises that also interior receipts open formula watch chain structure 12 outward, and interior receipts are opened formula watch chain structure 12 outward and are arranged on quiet end conducting rod 1 and the moved end conducting rod 5 junction with sleeve pipe.Receive an outer formula watch chain structure 12 in on-pole switch and sleeve pipe adopt, the little current capacity of contact resistance is strong and easy for installation.
Referring to Fig. 1 to Fig. 4, the specific implementation step is first with quiet end conducting rod 1, vacuum interrupter 2 before cast, cast box 3 is flexible coupling 4, moved end conducting rod 5, the first connecting pin 6, pull bar connecting stud 7, transmission crank arm 8, the moved end connects guiding connecting lever 9, the second connecting pin 10, the 3rd connecting pin 11, by order and structure install, and then opsition dependent is fixed to and carries out at last injection moulding or cast in the mold cavity again.This advantage of admittedly sealing body is to have realized the cast of more structural entity, makes an electrified body realize cast with the running part one, and adopts the watch chain structure to be connected between body and the sleeve pipe, convenient later on installation.
The invention provides a kind of simple in structure, reliable, have good electric property, and compare before the less solid envelope body of the safer more environmental protection of gas-filled switching tube volume.This insulation shell 13 is with all injection mouldings or be cast in the insulation shell 13 interior realization all insulations that epoxy resin forms of switch operation assembly, reach safe and reliable, and vacuum interrupter 2 assembles in advance injection moulding with the moved end transmission component or is cast in the insulation shell 13, so that assembling is simpler.Admittedly it is easy for installation to seal body, high conformity between phase and phase, sleeve pipe is connected with insulating cylinder well, can realize good insulation property, and more minor structure is also more reasonable attractive in appearance also to make the ZW20 volume of switch simultaneously.Solid sealing switch body adopts the integrated poured mode of epoxy resin seal on the post, the switch operation assembly all is enclosed in admittedly realizes all insulation in the epoxy resin, and cancel sulfur fluoride gas and reached environmental protection, so owing to adopt solid insulation not have the gas leakage problem, safer; Cancel irrational inserts solved the office put problem, removed potential safety hazard; Make part parts integral module installation more convenient.
