状態にかかわらず直ちに蓄勢されるものである。Conventional technology Conventionally, in the switching devices of shield breakers and electromagnetic contactors that use oil, air, gas, vacuum, etc. as the arc extinguishing medium, the main operating shaft is interlocked and connected via contacts and link mechanisms, etc. A lever extending in a direction perpendicular to the longitudinal direction is fixed, and an operating spring made of a cylindrical tension coil spring is stretched between the end of the lever and a suitable fixing system to rotate a motor or the like. The main operating shaft is intermittently rotated about half a turn to store energy in the operating spring, and the opening or closing operation is performed by the remaining half turn of the main operating shaft when the closing spring is released. Note that the released closing spring is immediately energized regardless of the state of the contacts.

の放勢時に最小限レバーの長さの範囲内において
極めて短時間で、その長手方向と直交する方向の
振動が生ずることになる。 However, in a switching device such as a circuit breaker, it is required that the opening/closing operation of the contacts (electrodes), especially the opening/closing operation, be performed in an extremely short time. Therefore, when the closing spring is released, the end of the closing spring on the lever side vibrates in a direction perpendicular to the longitudinal direction within an extremely short period of time within the minimum length of the lever.

This may cause time fluctuations and burnout of the motor, and when the switchgear is of a drawer type, there are problems such as damage to the plug connected to and separated from the main circuit.

材を挿入してなるものである。 In view of the above points, conventional methods have been used to prevent vibration in the direction perpendicular to the longitudinal direction of the closing spring immediately after it is released, thereby reducing noise, preventing load fluctuations when re-energizing, and reducing vibration of the entire device. A switching device that can prevent various problems associated with this is known from Utility Model Application No. 80998 of 1981. In this prior art, the closing spring is formed of a cylindrical tension coil spring, and a vibration prevention member made of rod-shaped rubber or the like is inserted inside the closing spring.

た。Problems to be Solved by the Invention However, even when the closing spring is equipped with the above-mentioned vibration prevention member, there is a problem in that it is difficult to completely prevent vibration of the closing spring when the closing spring is released.

ねの振動防止具を取付けたことを特徴とする。Means and Effects for Solving the Problems The present invention further improves the above points. That is, it has a closing spring that has one end pivotally connected to a lever provided on the operating shaft that is interlocked with the contact, and the other end of which is pivotally connected to a fixed system. In a switchgear in which a contact is opened and closed by accumulating energy by half a rotation and releasing the energy by a remaining half rotation of an operating shaft, a buffer member is provided on a side frame of a housing of the switchgear and is in contact with a side of a closing spring. It is characterized by the attachment of a vibration prevention device for the closing spring consisting of a supporting metal fitting.

当ることによつて急速に減衰されるのである。 Therefore, according to the above configuration, the closing spring is
Energy is stored by intermittent half-turns of the main operating shaft, and the closing spring is released all at once by the remaining half-turns to complete the closing process.The intense vibration of the closing spring is prevented by a vibration prevention device installed on the side wall of the housing. It is rapidly attenuated by hitting the shock absorbing member of the tool.

Due to the operation of the motor 27, the operation main shaft 26 is intermittently rotated by about half a rotation via the rotational force transmission mechanism 28, and as the operation main shaft 26 rotates, the closing spring 29 is energized, and due to the operation of the closing electromagnet 58. The engagement of the closing hook 59 with the rotation period control cam 57 is released, and the operation main shaft 26 rotates half a rotation due to the release of the closing spring 29, and through the accompanying rotation of the closing cam 36, the link mechanism 30 and the transmission mechanism 5, the contact of each pole post 4 is closed, and the lever 24, which is energized when the contact of each pole pole 4 is closed, is activated by a tripping lever 46. 43 and the roller 34 of the link mechanism 30 and release the force, the contact points of each pole column 4 are finally severed.

ある。 Therefore, when the closing spring 29 is released, the lever 62 side is instantaneously moved within the range of the length of the minimum lever 62, and the closing spring 29 vibrates in a direction perpendicular to its longitudinal direction. When,
The vibration of the side surface of the closing spring 29 is quickly damped by the buffer member 72 of the vibration preventer 70.

奏する。Effects of the Invention As described above, according to the present invention, there is provided a closing spring whose one end is pivotally connected to a lever provided on an operating main shaft that is interlocked with a contact, and whose other end is pivotally connected to a fixed system. In a switchgear in which a spring is loaded with energy by intermittent half-turns of the operating main shaft, and which opens and closes a contact by the remaining half-turn of the operating main shaft after the spring is released, the casing of the device is provided with a Since a device for preventing vibration of the closing spring in the direction perpendicular to the longitudinal direction is provided, the vibration of the closing spring can be quickly damped, thereby suppressing the generation of noise as much as possible. As a result, it is possible to prevent load fluctuations, etc. when the closing spring is charged after releasing, and to prevent vibrations of the entire switchgear and various problems associated with this. play.
