Summary of the invention
Technical problem to be solved in the utility model all provide in the defective that overcomes prior art a kind of simple in structure, volume is little, be convenient to assemble and regulate and the arc control device branch of the vacuum insulation on-load switch of reliable in action, close mechanism.
Embodiment of the present utility model is:
The arc control device branch of described vacuum insulation on-load switch, close mechanism, it comprises a shell, bracket by isolation knife roller combined floodgate thrust and the promotion of separating brake thrust, realize the tripping spring and the moved end guide rod of arc control device branch, combined floodgate, guide rod is provided with excess of stroke spring, it is characterized in that described bracket is connected with the cam drive that is located at the shell aperture end, is subjected to the cam rotary lifting to make counter-rotational buckle, buckle is hinged and connected with the little axle that is supported on shell, and the effect of being buckled in mutually has on the semiaxis of torsion spring; Described moved end guide rod is made up of the top guide bar and the lower guide rod of mutual coaxial installation and flexible connection, flexibly connect with buckle again simultaneously, rotated by buckle and move up and down, and buckle is not held to be pressed on and is located on the coaxial mounted tripping spring of going up on screw rod and the following screw rod.
Described buckle end is pressed on the tripping spring (19) by the roller that bearing pin connected that is located in the screw rod oblong slots.
Described top guide bar and lower guide rod flexibly connect by the oblong slots that is connected bearing pin on the lower guide rod and top guide bar.
Described excess of stroke spring is the dish spring.
Compared with prior art, the utility model has been simplified the branch of realizing on-load switch arc control device branches, combined floodgate, has been closed mechanism, has adopted cam and buckle structure, makes designs simplification, volume-diminished, because parts reduce, processing cost reduces, coordination, reliable; Excess of stroke spring has adopted dish spring element, is convenient to adjust excess of stroke distance by the sheet number, makes assembling easy to adjust, and it is little to take up space.
Description of drawings
Fig. 1 is the structural representation of the utility model under "on" position.
Fig. 2 is the structural representation of the utility model under gate-dividing state.
Embodiment
Below with reference to above-mentioned accompanying drawing embodiment the utility model is elaborated again.
Shown in Fig. 1-2, the arc control device branch of vacuum insulation on-load switch, close mechanism and be fixed on the moved end of vacuum interrupter, it includes a shell 1, one bracket 10 by isolation knife roller combined floodgate thrust or the promotion of separating brake thrust is arranged, the bracket end one that links to each other with the camshaft 9 that is bearing in shell aperture end both sides, camshaft is provided with the cam 8 that key connects, form drive connection, be subjected to cam 8 rotation and make counter-rotational buckle 7 and be hinged and connected with the little axle 6 that is supported on the shell, buckle is buckled on the semiaxis 11 mutually towards next end, this semiaxis is rotated by cam drive equally, two ends are provided with torsion spring 12 on it, torsion spring one end and semiaxis are fixed, on the pillar 13 of the inconsistent wall in the enclosure of the other end, make semiaxis act on the power that a court is rotated counterclockwise all the time.
Guide rod two ends, moved end are with the shell expansion bearing, form by top guide bar 5 and lower guide rod 16 that bearing pin 14 flexibly connects by mutual coaxial installation, pass top guide bar oblong slots 22 and form flexible connection with the bearing pin 14 of lower guide rod close-fitting, top guide bar 5 flexibly connects by bearing pin 4 and buckle 7 again simultaneously, be subjected to the rotation of buckle and move up and down, realize arc control device branch, combined floodgate, dish spring 15 between the upper and lower guide rod is compressed in the guide rod folding process, produces reaction force and make to move on the guide rod and recover normal when guide rod moves down the excess of stroke.
Tripping spring 19 is located at mutual coaxial mounted two ends with on the detachable spring base 17 that is connected last screw rod 2 on the shell and following screw rod 18 of screw thread, last screw rod is provided with oblong slots 21, bearing pin 3 in the groove is connected buckle 7 ends with roller 20, this roller 20 is pressed on the tripping spring 19, and tripping spring can carry out regulating spring power by the nut on the following screw rod.
The utility model will further be understood branch, making process by the description of dynamic structure:
When bracket 10 is subjected to the effect of isolation knife roller (not shown) combined floodgate thrust and turns clockwise, cam 8 is rotated counterclockwise buckle 7 jack-up, the roller 20 of buckle end just compresses tripping spring 19 makes its energy storage, and the moved end guide rod is moved down, make vacuum interrupter be in "on" position, as shown in Figure 1.
Under "on" position, bracket 10 is owing to the effect that is subjected to isolation knife roller separating brake thrust is rotated counterclockwise, cam 8 jack shafts 11 clockwise rotate, when semiaxis turns to the moment that buckle 7 breaks away from the snapping amount, tripping spring 19 outburst energy, make the rapid disjunction of vacuum interrupter, mechanism is in gate-dividing state, as shown in Figure 2.
