The high-reliability high voltage AC single-phase isolating switch on the outdoor post comprises a left composite insulator, a right composite insulator and a movable blade, and is characterized in that the lower end of the right insulator is fixedly provided with a bracket, the bracket is provided with an outlet copper bar, the movable blade is of an integral bar structure, the right end is connected with the bracket through a rotating member, and the right end of the movable blade is connected with the outlet copper bar by adopting flexible connection; the lower end of the left composite insulator is provided with an inlet copper bar and a static contact arm connected with the inlet copper bar, the lower end of the static contact arm is fixedly provided with a plum blossom contact, and the left end of the movable blade is provided with a movable contact which is in on-off connection with the plum blossom contact. The high-reliability high voltage AC single-phase isolating switch on the outdoor post overcomes problems such as easiness in corrosion generation, loosening, inaccurate positioning in closing, short service life and the like of a common isolating switch, and is mainly applied to isolation for overhead lines with rated voltage being 12KV and below.
Description
Technical field
The utility model relates to high-tension electricity and carries device for switching, high-voltage alternating single-phase isolating switch on especially a kind of high reliability outdoor column.
Background technology
At present for isolating switch on the outdoor column of voltage 12KV and following high-tension line (referring to Fig. 1,2) mainly by left and right composite insulator 1 and 8, line copper bar 2 and 7 and cutting blade 4 form, cutting blade 4 of the prior art is to be fastened by bolt clip by two blades, its one end is rotatably connected with the fixed contact 6 on right composite insulator 8 by axle 5, and adopt spring 9 to strengthen conduction connection with this conducting outlet copper bar 7() simultaneously, the other end adopts 3 foldings of hook formula moving contact to be connected with right insulator, realizes separating brake, the closing operation of isolating switch.Because isolating switch is in long-term work process, cutting blade and dynamic and static contact, friction, very easily cause surface abrasion, thereby cause blade heating, distortion, finally cause the location of closing a floodgate inaccurate, destroyed the electric property of isolating switch, greatly shortened the useful life of isolating switch.
Summary of the invention
The purpose of this utility model will solve high-voltage alternating single-phase isolating switch on existing outdoor column exactly, conductive contact surfaces is easy to wear, and the blade distortion of easily generating heat causing the location of closing a floodgate inaccurate, the problems such as useful life is short, provide high-voltage alternating single-phase isolating switch on a kind of high reliability outdoor column.
Concrete scheme of the present utility model is: for high-voltage alternating single-phase isolating switch on common outdoor column, improve, it includes left and right composite insulator and cutting blade, it is characterized in that: in right composite insulator lower end, support is fixedly housed, outlet copper bar is housed on support, described cutting blade is integral type member structure, its right-hand member is connected with support by rotating parts, and the right-hand member of cutting blade adopts to be flexible coupling simultaneously and is connected with outlet copper bar; Inlet wire copper bar and the stationary contact arm being connected with inlet wire copper bar are housed in left composite insulator lower end, in stationary contact arm lower end, Mume flower contact are fixedly housed, at the left end of described cutting blade, moving contact is housed and is connected with Mume flower contact opening and closing.
Being flexible coupling between cutting blade described in the utility model and outlet copper bar is flexible coupling for red copper.
Rotating parts between cutting blade described in the utility model and support is to adopt aluminium alloy hinge.
The red copper conduction that is flexible coupling has been introduced in one end of the present utility model, and the other end adopts Mume flower contact opening and closing to connect conduction, has avoided the possibility of blade because of wearing and tearing heating distortion completely, combined floodgate accurate positioning, and never distortion, greatly extend useful life.The utility model is simple in structure, compactness, handling safety, convenience, stable and reliable operation, combined floodgate accurate positioning.
