The mode that interlocking lever 191 can move up and down is arranged in breaker body 110 places.
More specifically, interlocking lever 191 mode that can move up and down is arranged on the upside place of sliding part 170.
As shown in figure 15, interlocking lever 191 can be constructed to have for example cylinder form.
The mode that interlocking lever 191 can move up and down is arranged between two side wall portions 172 of sliding part 170.
Be cut the upper end that can be arranged on interlocking lever 191 with the interlock board 195 that extends towards interlocking lever 181.
The interlocking plunger of arranging in vertical direction with respect to interlocking lever 191 197 can be arranged on interlocking lever 191 places.Jack 192 can form the lower area that penetrates interlocking lever 191 and insert wherein to allow interlocking plunger 197.
As shown in figure 13, can be arranged on sliding part 170 places with interlocking plunger 197 contacted recess projections 175.Because this layout during interlocking lever 191 moves down, can suppress the movement of sliding part 170 on fore-and-aft direction.
The mode that the side direction portion (front side is to portion) of formation recess projection 175 can tilt forms.In the closed position of driving shaft 126, handle 160 can be inserted into so that breaker body 110 is mobile in direction forward or backward.At this moment, handle 160 can make rotation inhibition unit 150 be squeezed and rearward move up.If rotation suppresses unit 150 and sliding part 170 is mobile together on backward directions, the front side of recess projection 175 can rearward move up to portion 176 so.In this process, interlocking plunger 197 can be along the front side of recess projection 175 to portion 176, and namely inclined surface 176 is moving up upward, and therefore places and be supported on the upper end of two side wall portions 172 of sliding part 170.At this moment, rearward moving up if rotation suppresses unit 150, because rotation suppressing portion 146 is released from rotation suppressing portion jack 157, therefore transmitting screw rod 141 becomes rotatable state so.In addition, be inserted in the handle 160 so that handle 160 rotations transmit screw rod 141 so and can rotate along the direction of rotation of handle 160 if transmit the handle connection part 148 of screw rod 141.
The interlocking lever guide 210 that moves up and down that is used for guiding interlocking lever 191 can be arranged on a side of interlocking lever 191.
For example, as shown in figure 16, interlocking lever guide 210 can be constructed to have roughly " U " tee section shape, and it has two vertical wall portion 212 that are separated from each other and the connecting portion 214 that is used for connecting two vertical wall portion 212.Here, two vertical wall portion 212 can be separated from each other to have inner width, and sliding part 170 is contained between this inner width in the mode that can relatively move.Containing hole 216 can be formed on connecting portion 214 places, so that interlocking lever 191 can penetratingly insert wherein in the mode that can move up and down.Interlocking plunger containing hole 215 can be formed on vertical wall portion 212 places, so that interlocking plunger 197 can penetratingly insert wherein in the mode that can move up and down.Because this layout, when sliding part 170 when rearward moving up, the interlocking plungers 197 that are tilted surface 176 extruding can be directed in upward direction.
Simultaneously, interlocking the latch 220 that moves in the rotation that interlocks lever 181 can be arranged between interlocking lever 191 and the interlocking lever 181.
More specifically, latch 220 can be constructed in the inhibition position and allow to rotate between the position.For example, as shown in figure 14, latch 220 can comprise main body 221 and be formed on rotating shaft 223 in the zone of main body 221.
The main body 221 of latch 220 can form plate-shaped.
The path that moves up that is arranged in interlocking lever 191 is sentenced the side that the main shaft portion 225 that moves up that suppresses interlocking lever 191 can be arranged on the main body of latch 220.Inferior axis portion 226 can be arranged on a side of main shaft portion 225 along the direction of rotation of main body 221.Can be constructed so that main shaft portion 225 has apart from the big relatively radius (R1) at the center of rotating shaft 223, and inferior axis portion 226 has apart from the relatively little radius (R2) at the center of rotating shaft 223.
Connecting pin 227 can be arranged on main body 221 and sentence with rotating shaft 223 and separate predetermined distance.Connecting pin 227 can with interlocking lever 181 combinations.Because this layout, latch 220 can interlock in the revolution of interlocking lever 181 and around rotating shaft 223 rotations.According to above-mentioned structure, even interlocking lever 181 is rotation further above the precalculated position, interlocking lever 181 also can not contact with interlock board 195 and latch 220 slightly is further rotated above the precalculated position around rotating shaft 223, and the collision contact between therefore can generation part.Therefore, can suppress because the collision between the parts contacts parts damages and the distortion that causes, thereby prolong component life and guarantee operating reliability.
According to above-mentioned structure, when breaker body 110 places arbitrary place of test position or run location and vacuum interrupter 120 to place open position, interlocking lever 181 can separate with interlocking lever 191 and as shown in Figure 5 upwards revolution in order to be disposed in the place, off-position.At this moment, latch 220 is in the state that the interlock board 195 of as shown in figure 17 main shaft portion 225 and interlocking lever 191 is separated, and therefore interlocking lever 191 can move up and not hinder latch 220.
When vacuum contact maker 120 placed open position, breaker body 110 can move up in front and back.If suppressing the handle 160 at the place, front side of unit 150, rotation is extruded in backward directions, rotation inhibition unit 150 is rearward moving up so, and suppresses unit 150 with rotation and push the interlocking plunger 197 of interlocking levers 191 and it is moved up to portion 176 in the front side of the inclination of the recess projection 175 of the sliding part 170 that rearward moves up.If suppressing unit 150, rotation rearward moving up, so the restriction that transmits screw rod 141 is released, and the handle connection part 148 that transmits screw rod 141 combines with handle 160 can be based on the direction of rotation of handle 160 and forward and counter-rotating so that transmit screw rod 141, and therefore breaker body 110 can be in forward direction (for example, test position) or backward position (for example, run location) is transmitted.
Remove if handle 160 suppresses unit 150 from rotation, rotation inhibition unit 150 can be restored to initial position by unshowned spring in the accompanying drawing so.At this moment, because move to initial position and therefore can not be supported and recess projection 175 is placed the downside place of interlocking lever 191 at sliding part 170, interlocking lever 191 can move down.
In this state, when driving shaft 126 rotates to make position, interlocking lever 181 can be rotated down, and as shown in figure 18, being connected to the latch 220 that interlocks lever 181 by connecting pin 227 can be towards restriction site or lock position (on the clockwise direction in the drawings) rotation.
If latch 220 rotations are to the lock position, the main shaft portion 225 of latch 220 can be arranged in moving up or down on the path of interlocking lever 191 so.More specifically, the main shaft portion 225 of latch 220 can be arranged as with the upside of interlock board 195 and contact.Because this layout can suppress moving up of interlocking lever 191.At this moment, even use leading section (transmitting screw rod connection part 162) the extruding rotation of handle 160 to suppress unit 150, recess projection 175 also contacts with the interlocking plunger 197 of interlocking lever 191, thereby suppresses the mobile backward of sliding part 170.Therefore, can suppress to rotate and suppress the mobile backward of unit 150, and transmit screw rod 141 and can not mutually combine with handle 160, thus the rotation that suppresses to transmit screw rod 141.
