本発明は衝撃吸収機能を備えた開閉装置用操作装置に関
する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an operating device for a switchgear having a shock absorbing function.

いる。尚、ストッパー１１ａは図示していない。A conventional operating device for a switchgear has a configuration as shown in FIG. That is, by electric or manual operation, the drive spring 10 is compressed and stored via the ratchet 1 and the wheel 2, and when it becomes in line with the arm 4 fixed to the connecting cam 3 (compression dead center), it is most compressed, and then immediately released. The connecting cam 3 is connected to the equipment main shaft 5.
The structure is such that the main shaft 5 of the device is connected to a connecting cam 6 connected to the main shaft 5 of the device, and the movable contactor 8 of the main body of the device is operated via the lever 7 connected to the main shaft 5 of the device. Stoppers (lla) arranged on the left and right sides of the arm 4 of the connecting cam 6
, (llb) are used to prevent over-rotation of the main shaft 5 of the equipment. Note that the stopper 11a is not shown.

になってくる。An oil damper 9 disposed between the operating device and the main body of the device is provided to absorb and reduce the impact force caused when the movable contact 8 stops moving. However, this damper 9 has a considerable space, and if it is placed in the operating device in this state, the operating device will become large and inspection etc. will become difficult.

動作する不具合もある。In addition, since it is connected to the main shaft 5 of the equipment, it operates throughout the entire process of the main shaft operation, so there is a problem that a buffering effect acts on the entire process of the operating force of the operating device. The buffering effect is necessary only immediately before the end of the shutoff, and the buffering effect during the entire process results in a loss of power for the operating device. In addition, if the oil damper 9 is too effective or vice versa, the main shaft 5 of the equipment is directly linked to the operating device, causing the main shaft 5 to counter-rotate or over-rotate, causing chattering in the auxiliary switch 19 etc. connected to the main shaft 5. There is also the problem of electrical malfunction.
本発明は上記問題点を除去する構成されたもので小型か
つ信頼性の高い開閉装置用操作装置を提供することを目
的とする。SUMMARY OF THE INVENTION An object of the present invention is to provide a small and highly reliable operating device for a switchgear which is configured to eliminate the above-mentioned problems.

かな停止及び装置の小型化を図るようにしている。In order to achieve the above object, in the present invention, an arm is fixed to the main shaft that transmits the driving force to the movable contact, and a shock absorber having a stopper function is attached to this arm, so that the stopper and the damper are common. This allows for gentle stopping of the main shaft and miniaturization of the device.
本発明の一実施例を第１図及び第２図により説明する。 An embodiment of the present invention will be described with reference to FIGS. 1 and 2.
第１図は本発明の全体構成であり、第２図はダンパ一部
の詳細図である。FIG. 1 shows the overall configuration of the present invention, and FIG. 2 is a detailed view of a portion of the damper.

了近くで当接させ、緩衝効果が働くようにしている。Oil dampers 128° 12b having a buffering effect are arranged on the left and right sides of the connecting cam 3 for the closing and shutting off of the movable contact 8, respectively, and are brought into contact with the arm 4 fixed to the connecting cam 3 near the end of loading and shutting off, thereby damping the movable contact 8. I'm trying to make it work.
オイルダンパー１２ａ、１２ｂの構成を第２図により説
明する。The structure of the oil dampers 12a, 12b will be explained with reference to FIG.

復帰するようになっている。Oil 15 is inside the cylinder 14 sealed with the lid 13.
The piston 17 having a throttle hole 16 is slid in the cylinder 14, and the piston 17 is brought into contact with the arm 4 fixed to the connecting cam 3 near the end of its operation, and the oil 15 passes through the throttle hole 16 and is moved into the arm. It is discharged to the 4th side and a buffering force is generated. Furthermore, when the arm 4 rotates in the opposite direction, it is automatically returned to its original position by the restoring force of a compression spring 18 disposed at the bottom of the cylinder 14.

９等のチャタリングを防止できるようにした。By providing these oil dampers 12a and 12b,
By eliminating the conventional stoppers 11a and llb shown in FIG. 3 and placing them inside the operating device, the space of the entire switching device can be reduced, and the buffering effect is activated only immediately before the closing and closing of the movable contact 8 is completed. Since the drive spring 10 is connected to the arm 4, the auxiliary switch 1 is activated by the reverse rotation of the device main shaft 5 for reverse charging after the drive spring 10 is released.
Chattering of 9th class can be prevented.
また、機器主軸５とダンパー１２ａ、 １２ｂを分括に
した為、組立、調整が容易になった。Furthermore, since the main shaft 5 and the dampers 12a and 12b are separated, assembly and adjustment are facilitated.

。As explained above, in the present invention, an arm is fixed to the main shaft that transmits the driving force, and a shock absorber having a stopper function is attached to this arm, so that the shock absorber and the main body of the operating device are housed in the same container. Therefore, it is possible to provide a small and highly reliable operating device for a switchgear.
