In the event that the contact is actually opened, the operating handle will not be able to move to the OFF position, and the operating handle will be secured so that the OFF state can be visually confirmed to improve safety. It is something that

や、゛特に配縁用遮断器に極めて広く応用されている。In general, a low-ratio air switch device is capable of opening, closing, and energizing the load current of an electric circuit, and is also capable of disconnecting the electric circuit when the switchgear is in the "off" state. In addition to the above, a low-pressure air interrupting device equipped with a mechanism that interrupts the electrical circuit in abnormal conditions such as overcurrent or short circuit, such as an air circuit breaker or a molded case circuit breaker, has a current interrupting function added to the above. On the other hand, in pressure circuit breakers, even when the arc extinguishing device is generally am and the circuit breaker is off, there is still a floating static connection between the input and output terminals, and there is a light disconnection with respect to the circuit voltage. It cannot be said that it is in the state, and a disconnecting means such as a disconnecting switch is generally used in conjunction with it.Low-pressure air switchgear, especially low-pressure air disconnection equipment, often handles incoming current tIl, so when the circuit is turned on, the electromagnetic force is In order to ensure safe loading, the most common method is to use mechanical force such as a spring or electromagnetic force such as a magnet to do the loading. One of them is a quick-on/quick-off method using a so-called toggle mechanism, which is extremely widely applied to low-pressure air switches in general and circuit breakers in particular.

。On the other hand, switchgears similar to this one, including this camphor molded circuit breaker, cannot directly see the contact status of the contacts for safety in handling and compactness, so the operating handle is not used in the on or off state. When the operating handle is rotated to the on side, it stops at the position where it is turned to the on side, and when one circuit is off, it stops at the position where the operating handle is rotated to the opposite side, so you can tell whether the circuit is on or off based on the rest position of the operating handle. Separate. Also,
A molded case circuit breaker with a free trip mechanism has a trip position. In this type of switchgear, the general number plate type Il
It has a reasonable distance between input and output, has sufficient withstand voltage performance, and has few stray electrostatic connections.

を行うと人命拳故に発展する危険が生じることがある。Generally, this state has been treated as a disconnected state. Turn on the (mouth) path by such operation handle position,
Judgment of the off state is inaccurate because the on/off state of the contact is not directly observed visually. For example, if the circuit breaker trips in an abnormal state while the operating handle is held in the on position, the circuit will be turned off, but since the operating handle is held in the on position, the problem is that the two do not match. However, the most important drawback is that this Hinoki electric switch opens and closes a movable contact device using a toggle mechanism consisting of an operating handle, an operating spring connected to the operating spring at one end, and a toggle link. In the unlikely event that a situation arises in which you bathe in a bathtub with the button on, move the operating handle to the off position, and the operating spring will be stretched more than normal and the operating handle will stop moving to the off position. The open position of the operating handle that can be seen visually without the open position Wt display of the operating handle and the actual off state of the contact Judging,
If construction or inspection/repair is performed on the load side of the electrical switch, there may be a risk of life-threatening consequences.

な判断の畝紹を生じ。The present invention comprises at least a pair of contacts 6, 9 that move relative to each other to open and close as described above, and a movable contact guide l for mounting one of the contacts! A pair of toggle links whose open ends are connected to the movable contact device 7 and are in contact with the toggle link shaft 2j,
Toggle link mechanism consisting of 3 parts and fixed frame/94
An opening/closing lever 17 which is rotatable and has an operating handle portion 16 supported at one end and operated from outside the closure jacket.
In addition, the contactor 6. is provided with a toggle type opening/closing operation 1a structure consisting of an operating spring roller installed between the opening/closing lever 17 and the toggle link shaft j. The opening/closing lever 17 and the toggle link mechanism are designed so that the operating handle section 16 cannot be moved to the off position in the case where the operating handle section 16 is moved to the off position only when #1 error occurs between the opening and closing lever 17 and the toggle link mechanism. A blocking member that locks or collides with the chest side of the connecting joint, for example, a notch provided in the opening/closing lever 17 /7'b, is bent and locks 9/7C, /7Q and the toggle of the toggle link a1111. Since the link shaft S or toggle links 2.2, 2J, etc. are formed, it has the conventional toggle type opening/closing operation**, and is turned on and off at the position of the operating handle protruding from the closure jacket. In the electric switch that determines the off position, even if the contact is wet, the operating spring will extend more than normal, causing the operating handle to stop moving to the off position or reset position. This allows OJ to accurately judge the open state of the two-contact barrier.

を逸脱するものではないAlthough this invention has been described with reference to a circuit breaker as an embodiment, it is applicable to a switch in this building in which the overcurrent response device and free tripping mechanism of the circuit breaker are removed or disabled so that only on/off operations are performed. It goes without saying that this also applies to the connection between the opening/closing lever 17 and the toggle link mechanism so that the contactor only engages or abuts each other when the contactor is in the bath and prevents operation to the OFF position. Even if various modifications are made to the blocking members provided in correspondence with each other, this will not depart from the scope of the present invention.
