Description

[Technical Field] The present invention relates to a gas shutoff device for a power source, and more particularly to a gas shutoff device for a power supply that is applied to a local voltage specification for a substation, a switchyard, or the like. [Prior Art] A gas shut-off device for power supply at a substation and a switchyard (hereinafter also referred to simply as "interrupter") is used as a drive source for shut-off and turn-on, which is an example of a so-called spring operating mechanism. It is described in the following patent document 1. In the circuit breaker of δ, which is described in Patent Document 1, as a driving source for blocking and turning-on, a coil spring is particularly used, and the components of the pulling-off control mechanism are engaged with each other to maintain the driving of the blocking spring. Force, when an input interrupt command is input, the solenoid will drive to release the engagement of the part and perform the blocking action. Further, a return spring is attached to the snap-in trigger of the solenoid press, and the structure is often energized for the interrupt trigger. [Problem to be Solved by the Invention] The gas interrupter described in Patent Document 1 has a structure that can correspond to, for example, two-cycle interruption. The high-speed interruption, but the lack of attention to the large capacity is that if the spring force of the breaking spring of the driving source is increased for the temporary breaking, the load acting on the rocker of the pulling control mechanism is increased, and the pressing is blocked. The load on the solenoid of the trip trigger will also increase. Therefore, the engagement release time of the occlusion trigger at the time of the interruption operation is also delayed, and there is a possibility that the speed cannot be increased. On the other hand, in general, although the magnetic circuit of the 142426.doc 201013726 is improved by the solenoid to increase the attractive force, it is correspondingly 'but if the method is used, the type of the solenoid will increase 'a' Seek commonality or standardization of parts. The present invention has been made in view of the problems of the prior art mentioned above, and the purpose of the invention is to reduce the negative of the interrupting trigger by reducing the negative of the interrupting trigger in the gas interrupter using the spring in the driving source. Such as commonalization or standardization, and reduce the working hours of the design of the interrupter. [Technical means for solving the problem] In order to solve the foregoing problems, according to the present invention, there is provided a gas interrupter for a power supply, which has a contact point which is disposed at a grounding capacity (4) and has a fixed contact member and a movable contact member; The pull-off control mechanism opens and closes the contact point by using the power of the blocking spring and the spring, and switches the power supply to the power-disconnecting disk, and the power of the blocking spring is solenoid and interrupted. The trigger is held or opened, and is characterized in that: in the pull-off control mechanism towel, a resetting mechanism for triggering the material is provided corresponding to the solenoid, and the return spring is configured to have a blocking n The elastic force in the on-hold state is smaller than the occlusion, the elastic force at the position is small, and the displacement of the occlusion trigger is non-linearly increased. Since then, the restoring spring force acting on the severing trigger is in the on-hold state: the minimum state and the maximum at the end of the severing state, but the occlusion trigger is configured to achieve the same speed. When the engagement with the rocker is released/twisted, the force of the return spring increases linearly with the rotation of the severing trigger. According to this, in particular, in the gas interrupter using a spring in the drive source, the load of the interrupter can be reduced by reducing the load of the occlusion trigger 142426.doc 201013726 and the designer of the interrupter can be reduced. The working hours of common or standardized production. Further, according to the present invention, as a specific structure for realizing the above-described restoration magazine, the following structure is preferable: the restoration spring is constituted by at least two or more compression coil springs, and is connected to the aforementioned breaker. In the holding state, one end of the restoring spring of one or more of the two or more compression spiral buds _ ping ping is said to be a severing trigger, and the other end of the restoring spring is disposed before the front end

The position at which the occlusion trigger a is energized, or at least two return springs or the above-described restoration at the position where the occlusion trigger I and the occlusion spring are pressed to the occlusion trigger The bullet is composed of two compression coil springs which are combined in a concentric circular shape and free length; or the restored elastic cyanine is composed of a (four) contraction (four) spring having a different pitch; or the restoration elastic system is pressed from the above by a spiral average The movable end of the interrupting trigger is formed by adding a conical spiral spring to the fixed end. [Effects of the Invention] According to the present invention described above, in particular, the gas k-breaker using the coil spring of the drive source can be turned on and held with respect to the load of the solenoid which is increased in capacity with the breaker. The load of the solenoid is reduced, thereby achieving the A-speed interruption, and at the same time, the commonalization and standardization of the solenoid can be sought, and the man-hours for designing and manufacturing the interrupter can be reduced.

Then, at the intermediate portion of the severing trigger Ma, a return spring 15 whose one end is fixed to the small frame 61 and 帛 to return the rupture trigger Η to the original position is attached. Next, the principle of operation of the spring operating mechanism 4A configured as described above will be described with reference to FIG. 2 and further including FIGS. 3 and 4. That is, 142426.doc 201013726 The opening and closing operation of the contacts is sequentially performed in accordance with the changes of Figs. 2 to 4 . First, the action of moving the ON state shown in Fig. 2 to the blocking state shown in Fig. 3 is stated. In the ON state, when the occlusion command is input to the occluder, the excitation pull-off control mechanism 401 pulls off the solenoid 2〇1, and the plunger 211 protrudes upward, and then the protruding plunger 211 is pressed. The third trigger triggers the rocker Mb (refer to the figure)

Arrow). As a result, the engagement between the interrupting trigger 14a and the second blocking latch 11 is released. The second escaping latch 11 that is disengaged from the escaping trigger 143 is rotatably rotated, and the pressing of the roller 1 遮 of the shackle 8 is rotated counterclockwise about the axis lu (refer to the figure). Towel arrow). By this, the flash button 8 is made to be free to rotate.

...: Only by the pressing of the roller 7 of the main shaker 5, the blocking latch 8 is rotated counterclockwise with the shaft 8a as a heart (refer to the arrow in the figure). Thereby, the snapping 8b of the flash button 8 is moved, and the main rocker 5 becomes freely rotatable, that is, because the shrinkage spring 26 is out of the limit before, the gj is the spring of the blocking spring. Release & m rocker 5 rotates counterclockwise (see arrow in the figure). Thereby, the connecting rods 31, 32 are also driven, that is, the movable contact member can be separated from the fixed contact member to open the joint. Then the occlusion spring % release potential energy is completed, and the breaking action is finished. Further, at this time, the end 6 of the end portion of the main rocker 5 is not stopped as shown in Fig. 37, and is stopped after substantially contacting the outer peripheral surface of the cam 3. Then, from the attached figure 3, the movement of the strong movement is moved, "two = to: = -

When the ON command is input, the solenoid 30 is turned on. At H 142426.doc 12 201013726 'Pressing the turn-on trigger, the plunger 311 of the universal solenoid 301 that unlocks the flash button 19 is protruded downward. Thereby, the turn-on trigger 22 is rotated counterclockwise, and the roller 21 is engaged with the turn-on trigger 22. By the engagement of the roller 2i and the hair-receiving device 22, the buckle 19 that has been previously restrained from rotating becomes freely rotatable, and then the buckle 19 is turned on by the pressing force of the cam (4). Turn counterclockwise (see arrow in the figure). Accordingly, the engagement of the buckle 19 with the roller 18 of the cam 3 is released.

Then, by releasing the roller of the buckle 19 and the cam 3, the rotation of the cam 3 becomes unrestricted, thereby releasing the spring of the spring 28: potential energy 'and turning the spring link 27 toward Below (4), the _ large gear 52 and the cam 3 rotate counterclockwise about the rotation axis 2 (see an arrow in the figure). Further, with the rotation of the cam 3, the main rocker 5 is rotated clockwise by the (four) operation abutting against the outer peripheral surface of the cam 3 (see an arrow in the figure). Thereafter, the cam 3 is substantially rotated by half, and the outer peripheral surface of the cam 3 abuts against the roller 6 of the main rocker 5 at the maximum radius of curvature portion thereof. At this time, the blocking spring link 25 connected to the main rocker 5 is compressed to compress the breaking spring % to the original position. On the other hand, when the closing spring 28 releases the potential energy, the contact 29 is turned on. Further, when the closing operation is completed, the respective shake cups 8, 11, and 14 constituting the pull-off control mechanism 4〇1 are restored to the original positions by the force of the return springs 9, 12, and 15, respectively. Break spring force 26. Furthermore, the state of this turn-on operation is as shown in Fig. 4. In this state, when an occlusion command is input, the occlusion action can be performed immediately. Here, the operation of the accumulating spring 28 is performed after the end of the closing operation, and is described with reference to FIG. 4 attached thereto. Further, in the figure, after the interrupter detects that the release potential of the closing spring 28 is completed, the motor (not shown) is started to rotate the pinion 51 clockwise. Thereby, the large gear 52 that is in contact with the pinion 51 is rotated counterclockwise (see an arrow in the figure). Along with this, the spring link 27 is turned to rotate counterclockwise, and the spring 28 is compressed. The large gear 52 is approximately 180. When the rotation (as in the above-mentioned Fig. 2) is made, the motor is stopped by the instruction of the restriction switch (not shown). At this time, the large gear 52 is further rotated counterclockwise by the driving force of the first spring 28, but the roller 18 of the cam 3 coaxial with the large gear 52 is engaged with the closing latch, and The roller 21 that turns on the flash button 19 is engaged with the turn-on trigger 22 (as described above with reference to Fig. 2), so that the rotation of the cam 3 and the large gear 52 is prevented, and the spring force of the spring 28 is kept. Accordingly, as shown in Fig. 2 above, the contact is in the ON state, and the initial state of the compression interrupting spring 26 and the closing spring 28 is returned. Next, in the present invention, the commonality or standardization of the trigger, the solenoid, and the like which constitute the interrupter is added to the method of reducing the load of the interrupting trigger. Furthermore, this method, especially in the operation box of the gas interrupter! The spring operating mechanism housed inside the 04 includes, in particular, the pull-out solenoid 2〇1, the second shut-off latch 11, the rupture trigger 14, and the rupture trigger, which constitute the pull-off control mechanism 401. The return spring 15 is hereinafter referred to as a pull-off control mechanism. <Embodiment 1> First, a third embodiment (Embodiment 丨) of the present invention will be described in detail with reference to Figs. 5 to 7 as will be described below. Further, Fig. 5 is an enlarged view showing the state of the pull-off control mechanism when the shutter is turned on, and Fig. 6 is an enlarged view showing the state of the 142426.doc •14-201013726 at the time of the occlusion. Further, Fig. 7 is a view showing the relationship between the rotation angle of the escaping trigger 14 and the return spring force in the pull-off control mechanism. As can be seen from Fig. 5 and Fig. 6, in the present embodiment, the return spring I5 constituting the above-described pull-off control mechanism is constituted by 1% of the two return springs 15a'. Further, one end of the return spring is fixed to the small frame 61. In the hold state shown in Fig. 5, one of the return springs 15a energizes the interrupting trigger 14, but the other return spring 15b does not contact the interrupting trigger 14. Then, in this state, when the escaping trigger 14 performs the blocking operation and rotates counterclockwise, the severing trigger 14 first compresses the return spring 15a, and further compresses the return spring 15b from the middle. Then, in the occlusion state shown in Fig. 6, the occlusion trigger 14 is in a state of compressing the two return springs 15. Here, the return spring 15 functions to terminate the restoration of the second escaping latch 11 and return the escaping trigger 14 to the original position when the closing operation is completed. In particular, in the foregoing FIG. 6, the force relationship between the occlusion trigger 14 and the severing trigger 14 is the axis 1 牝 and the small frame 61 of the occlusion trigger as a load. The friction torque Tc and the elastic force of the return spring 15 as a driving force. Further, although the second shackle of the latch shackle 3 is in contact with the severing trigger 14, the pressing force is only a component of the restoring spring 12 of the second escaping latch 11, so that it hardly It will affect the recovery action of the occlusion trigger 14, which can be ignored here. Generally, the "torque torque Tc" is smaller than the driving torque by the return spring 15, and particularly when the elastic force of the return spring 15 is weak, the driving torque for returning the rupture trigger to the original position becomes small. As a result, the recovery delay of the trigger bucket is interrupted, and the second interruption of the triggering operation may be 142426.doc 201013726, depending on the situation, the engagement of the light 13 of the buckle 11 with the occlusion trigger 14 fails. This results in an erroneous interrupting action. On the other hand, when the elastic force of the return spring 15 is too strong, the rupture trigger 14 is continuously oscillated after returning to the original position, and therefore, the roller 13 of the second snagging buckle may be caused at the end of the closing operation. The snap failed. Therefore, the inventors and the like considered it necessary to adjust the elastic force of the restoration magazine. Regarding the adjustment of the elastic force of the return spring, the relationship between the rotation angle of the rupture trigger 14 and the return spring force is shown by FIG. When the interrupter is turned on, the angle of rotation of the interrupting trigger 14 is zero (〇). In the prior art, the return spring 15 is usually composed of only one linear spring. On the other hand, according to the present invention as described above, since the return spring 15 is constituted by the two return springs 15a and 15b, the elastic force of the middle return spring 15a can be made larger than that of the prior art as shown in Fig. 7 described above. Only one linear spring has a reduced spring force. Then, at the time of the blocking operation, the severing trigger 14 is pressed by the plunger 211, and at the moment of the engagement with the roller 13 of the second escaping latch, the escaping trigger 14 also presses another Recovery springs 15b. Further, regarding the spring coefficients of the two return springs, the coefficient at one point is larger than 15a (the coefficient of 15a < the coefficient of 15b). Then, at the end of the interruption, these two restoring spring forces act and are constructed to exceed the elastic forces of the prior art. According to the return spring 15 of the first embodiment, the force acting on the interrupting trigger 14 at the start of the interrupting operation is as shown in Fig. 5 described above. That is, as shown in the figure, the negative of the solenoid 201, F2"', if the friction of the plunger is ignored, is the frictional force between the roller 13 and the interrupting trigger 14 of the second blocking flash 11, Fn, axis i4e and The frictional moment Tc of the small frame 61 is the sum of the elastic force F] 5a of the return spring 15a. 142426.doc -16- 201013726 However, as in the prior art described above, in order to increase the restoring elastic force in the occlusion state in order to quickly restore the occlusion trigger, the restoring elastic force in the on-hold state is also increased, so the spiral The load on the tube 201 is increased. On the other hand, according to the embodiment of the present invention, the restoring spring is made up of two (plural) and only one of the return springs 15a acts in the on-hold state, so that the solenoid can be reduced as compared with the prior art. The load of 201 can speed up the interruption operation. In addition, in particular, the occlusion trigger 14 is at the end of the closing action.

In the restoration, the elastic force of the two restoration springs can also be restored in substantially the same time as in the prior art. As described above, in the present embodiment, the return spring of the rupture trigger 14 is constituted by two (plural) springs, and one return spring 15a often presses the severing trigger 14, and the other return spring 15b is pressed during the escaping action. When the trigger 14 is interrupted, the "H" can be configured to prevent the stable engagement of the roller 13 of the flash button 11 and the interrupting trigger 14 when the closing operation is completed, and the snail is started by the snail at the start of the blocking operation. High-speed operation with reduced line load. &lt;Embodiment 2&gt; Next, a second embodiment (Embodiment 2) of the present invention is shown in Fig. 8 attached thereto. Moreover, the embodiment "recovery spring 15" is composed of three I-reducing coil springs ..., H 15c, and in the on-and-hold state, only one return spring 15a presses the occlusion trigger in the compression coil springs (length) Μ, the other two revolving springs 15b 15c do not press the blocking trigger. The relationship between the rotation degree of the severing trigger 14 and the resilience bomb in the foregoing embodiment 2 is shown in FIG. The spring coefficient of the recovery spring, 142426.doc -17- 201013726 15b, 15c coefficient is better than the coefficient of 15a (coefficient 15 &&lt; coefficient 15b or coefficient 15c) In addition, the spring coefficients of 15b, 15c can be the same In this embodiment, the rotation of the severing trigger by the severing action is also configured to compress the return springs 15b and 15c in order, thereby reducing the recovery elastic force in the on-hold state and The same effect as that of the foregoing embodiment is obtained. Further, the number of the return springs is further increased, and in the ON state, the rupture trigger is pressed by only one return spring, and the same configuration as that of the foregoing embodiment can be obtained. Effect, cooked The embodiment of the present invention can be understood. <Embodiment 3> Further, the third embodiment (Embodiment 3) of the present invention is shown as an additional figure, and the configuration of the embodiment 3 is also the same as the foregoing. The same applies to the combination of the two return springs 15a and 15b. However, unlike the first embodiment, the structures are concentrically combined. Further, the structure of the third embodiment is Changing the free length of the outer return spring 15&amp; and the inner return spring 15b can change the elastic force accompanying the rotation of the interrupt trigger 14 to the restored elastic phase shown in Fig. 7, which is non-linear. This embodiment 3 also has the same effect as the foregoing embodiment, and further, by arranging the plurality of springs concentrically, the occupied volume of the return spring can be further reduced. <Example 4, Example 5> The fourth embodiment (Embodiment 4) of the present invention is as shown in FIG. 5, and the fifth embodiment (Embodiment 5) of the present invention is shown in FIG. 12, which is added. Representing that the return spring 14 is composed of only one spring 2426.doc •18·

201013726 15, Embodiment 4 (refer to FIG. 1!), by making the pitch of the springs unequal, the elastic force and the rotation angle of the interrupting trigger are non-linear. In addition, in the fifth embodiment (refer to FIG. 12), the spiral spring is connected between the one end of the spiral trigger 14 and the fixed end of the small frame 61 fixed to the opposite side thereof, so that the average diameter of the spiral is increased. That is, by using a so-called conical spring, the relationship between the elastic force and the rotation angle of the occlusion trigger has the above-described non-linearity. Further, in the above, (10) is an example of the relationship between the rotation angle of the rupture triggering core and the recovery elastic force. That is, during the interruption operation, the IU4 is triggered to maintain the spring coefficient of the linear shape at the initial stage of rotation, but the spring line is stuck to each other beyond a certain rotation angle, so that the effective number of rolls is reduced, and the number of bullets is increased. . Further, the fourth embodiment and the fifth embodiment which are configured as described above can obviously exhibit the same effects as those of the foregoing embodiment, and since they can be constituted by only one return spring, they are the same as the foregoing embodiment 3. Reduce its possession volume. Furthermore, in the foregoing embodiments, the method for restoring the occlusion trigger (4) to the original position is described in particular by a spiral spring, but the present invention is not limited thereto as long as the aforementioned functions can be achieved. That is, those skilled in the art will understand that other methods can be used as well.
