Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial field of application) The present invention relates to an operating handle with improved reliability of operation, and in particular, a control device for a pole switch (hereinafter referred to as a slave station).
Regarding the operation handle of.

(Prior Art) FIG. 5 shows an operation handle of a conventional slave station. As the operation of the operation handle, three types of “off”, “automatic”, and “on” are selected by rotating the handle portion 1 around the rotation shaft 2 of the handle switch. A spring return type switch is used in which the handle portion 1 is rotated to the “on” position and then returned to the “automatic” position when the hand is released. However, this switch turns off the handle 1.
When it is rotated to the position of, it does not return to the position of "automatic" but maintains the state of "off" position.

In case of power outage work due to power distribution work, short circuit, ground fault, etc. A lock pin 3 is attached to the handle portion 1 itself in order to prevent the handle portion 1 from moving from the “off” position to the “automatic” position due to contact with the operator. Further, the nameplate 4 is provided with a lock pin insertion hole 5, and the lock pin 3 attached to the handle portion 1 is inserted into the lock pin insertion hole 5 when the handle portion 1 is in the "off" and "automatic" positions. The handle 1 is locked by.

(Problems to be solved by the invention) When operating the slave station on the utility pole by switching the handle part 1 from the "off" position to the "automatic" position for distribution line construction or power outage work, the rotation of the handle part 1 is encouraged. If there is a mark, there is a possibility that it will overrun past the "automatic" position and come to the "on" position, causing an unnecessary closing command to the switch and causing the switch to close. Also, after turning on the switch, when you want to operate it, after turning on the handle part 1, "automatic"
However, if there is too much momentum to overrun to the “OFF” position, there is a possibility that the inserted switch will open.

As described above, it is an object of the present invention to provide an operation handle that does not easily overrun by operating the handle portion and improves the reliability of the operation.

[Constitution of device]

(Means and Actions for Solving the Problems) The present invention will be described with reference to FIGS. 1 and 2. A protrusion 6 is provided on the name plate side of the handle portion 1, and a lever 7 for moving the protrusion 6 in the vertical direction is provided on the handle portion 1. Further, the name plate 4 is provided with a guide groove 8 having a step corresponding to the moving position of the protrusion 6 by the operation of the handle 1. As a result, when the handle portion 1 is rotated, the protrusion 6 abuts on the stepped portion of the guide groove 8 at the "automatic" position, and is temporarily stopped to prevent overrun. Further, by operating the lever 7, the lever 7 can be rotated to the opposite "OFF" or "ON" position.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 is a configuration diagram showing an operation handle of the present embodiment.

In FIGS. 1 and 2, the nameplate 4 is attached to the operating surface of the slave station, and the nameplate 4 is provided with a lock pin insertion hole 5 and a stepped guide groove 8. Handle part 1
Is attached to the handle switch rotation shaft 2 that comes out from inside the slave station, and rotates to the "off", "automatic", and "on" positions. The lever 7 provided with the protrusion 6 is the handle 1
It is attached to each and moves in the direction of the arrow. The lock pin 3 inserted into the handle portion 1 is moved by inserting it into the lock pin insertion hole 5 provided in the nameplate 4 when the handle portion 1 is in the "off" and "automatic" positions. Lock it so that it doesn't exist.

In FIG. 3, the lever 7 is mounted in the mechanism accommodating groove 9 of the handle portion 1 by the lever rotation shaft 10 and the spring 11. When the lever 7 is moved in the arrow direction, the protrusion 6 also moves in the arrow direction. The lever 7 that has moved in the direction of the arrow is returned to its original position (state shown in FIG. 3) by the spring 11. The round hole provided in the lever 7 is for making it easy for a finger to be caught when operating the lever 7.

In FIG. 4, the handle portion 1 cannot be moved unless the protrusion 6 is moved along the guide groove 8 by inserting the protrusion 6 of the lever 7 into the guide groove 8 of the name plate 4.
Therefore, the handle 1 is switched from "off" to "automatic", "automatic"
When it is set to the "off" position, the handle portion 1 can be moved without moving the lever 7 because the left side position of the guide groove 8 and the original position of the protrusion 6 of the lever 7 are aligned.

However, the protrusion 6 of the lever 7 hits the portion a in FIG. 2 of the guide groove 8 that attempts to change the operation handle portion 1 from “automatic” to “in”, and the handle portion 1 cannot go to the “in” position. It remains in the "auto" position. Therefore, the handle portion 1
To change the position from "Automatic" to "On", move the lever 7 so as to push it toward the slave station operation surface, and the protrusion 6 of the lever 7 will move down to the right side of the guide groove 8. It can be in the "on" position.

As described above, since the handle portion 1 is stopped at the "automatic" position in the switching operation of "off" and "on", the overrun on the operation can be prevented.

[Effect of device]

As described above, since the operation overrun is prevented as in the present invention, a highly safe operation handle can be obtained.
