The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
Referring to fig. 1-4, an embodiment of the present utility model is provided: a high voltage vacuum circuit breaker comprising a bracket 2, a panel 1 mounted on the bracket 2; the bracket 2 is provided with a first linkage rod 4 and a second linkage rod 5; the first linkage rod 4 is connected with the second linkage rod 5 through a first transmission shaft 8, and the second linkage rod 12 is connected with a second transmission shaft; the driving ends of the first transmission shaft 8 and the second transmission shaft 12 are arranged on the panel 1; the upper end of the bracket 2 is also provided with a conductive terminal 3, and a mounting area 6 for mounting an electrode is arranged in the conductive terminal 3; the first transmission shaft 8 and the second transmission shaft 12 on the control panel 1 are used for enabling the first linkage rod 4 and the second linkage rod 5 to rotate, so that the circuit breaker can complete the power-off and separation actions.
In summary, the first linkage rod 4 and the second linkage rod 5 can be easily driven to rotate by the two transmission shafts on the control panel 1, so that the circuit breaker can conveniently complete the power-off and separation actions; the electrodes are arranged in the mounting areas 6, so that the electrodes are convenient to mount and replace. Based on the method, the structure of the equipment is optimized, so that the equipment is convenient to use and is convenient for the installation and replacement of the electrodes.
In addition, the panel 1 is provided on the side of the stand 2, thus enabling the overall structure of the apparatus to be compact while facilitating the operation of the user.
Further, since one end of the first linkage rod 4 is provided with the first connecting piece 7, and the other end of the first linkage rod 4 is provided with the second connecting piece 16; the first connecting piece 7 and the second connecting piece 16 are in threaded fit with the first linkage rod 4, so that the first linkage rod 4 is rotated to drive the two connecting pieces to move oppositely or move oppositely, the distance between the isolation disconnecting link and the support 2 can be adjusted through the first linkage rod 4, and meanwhile, the firmness of contact between the isolation disconnecting link and the contact is improved through rotation of the first linkage rod 4.
Because the end of the first connecting piece 7, which is far away from the first linkage rod 4, is connected with a first swing arm 15 arranged on the first transmission shaft 8. Therefore, the gap between the first linkage rod 4 and the first transmission shaft 8 can be reduced while the first transmission shaft 8 is ensured to reliably drive the first linkage rod 4 to act.
Further, the second link 5 is connected to the second transmission shaft 12 through a second swing arm 11, and a buffer member 9 is disposed between the second swing arm 11 and the second link 5, so that the impact force of the second transmission shaft 12 on the second link 5 can be buffered by the buffer member 9.
In particular, the buffer 9 comprises a third connection 13; the third connecting piece 13 is provided with two sliding frames 17 with identical structures at the outer part, and a spring 10 is arranged between the two sliding frames 17. The absorption of kinetic energy can thus be accomplished by means of the expansion and contraction of the spring 10.
Further, since the third connecting piece 13 is in threaded engagement with the second link 5, rotating the third connecting piece 13 again allows the gap between the second link 5 and the bracket 2 to be adjustable. Further, since the other end of the third connecting piece 13 is connected to the second swing arm 11 through the chute 14, the sliding of the second swing arm 11 in the chute 14 can be utilized to overcome the instant impact force of the second transmission shaft 12.
