Description

  This invention makes it easy to detect the number of rotations even when the number of rotations is less than one when the handle is manually rotated by a specified number of times, for example, in a confirmation test after a close inspection of the on-load tap switching device of a transformer. The present invention relates to a handle having a structure that can be used.

  In the load tap switching device of the transformer, the tap is switched by an electric motor during operation, but at the time of maintenance such as a confirmation test after a close inspection of the load tap switching device, for example, a manual handle as shown in Patent Document 1 Is connected to the rotating shaft cover of the electric operation mechanism of the on-load switching tap so that the tap can be manually switched, and this manual handle is rotated by a strictly set number of rotations (for example, 30 rotations). Switching taps is already known.

  For example, as shown in Patent Document 2, in order to eliminate the complexity of counting the number of rotations of the rotation spindle of the rotation operation handle by the operator himself, a rotation number detection unit that detects the rotation number of the rotation spindle, A valve opening / closing operation device including a rotation speed detector having a rotation speed display section for displaying the detected rotation speed in the vicinity of the operation handle section is also already known.

  However, any of the inventions described in Patent Documents 1 to 3 can detect only the number of revolutions per revolution and display it on the display unit. Therefore, the number of revolutions is strictly accurate including less than one revolution. If there is a need to re-execute the confirmation test if the rotational speed is miscounted, such as a confirmation test after a close inspection of the transformer load tap changer, the rotation angle display section Usefulness as a handle with a handle was not enough.

  Therefore, the present invention not only can detect and display the number of rotations of each rotation of the handle, but also makes it easy to detect the number of rotations less than one rotation of the handle by displaying the rotation angle of the handle. An object of the present invention is to provide a handle with a rotation angle display unit capable of

  The handle with a rotation angle display unit according to the present invention includes a rotary shaft that is attached to the operation mechanism of a device having an operation mechanism that is operated by an electric motor, and an electric power that is manually operated to rotate via the rotary shaft. A handle including an arm that transmits rotation to the electric motor that is not supplied; a storage portion that surrounds the rotating shaft rod from its circumferential direction; and a radially outer side of the rotating shaft rod from a rotation range of the arm; A counter display section provided in the storage section and a rotation speed detection mechanism for detecting the rotation speed of the rotation shaft rod, the rotation speed detection mechanism being the storage of the rotation shaft rod. A protrusion protruding in a radial direction of the rotary shaft rod from a side surface of a portion located in the section, and a contact with the protrusion disposed on the circumference along the rotation track of the protrusion in the storage section ON by A plurality of switch units to be turned off, a switch unit ON / OFF detection circuit for detecting the number of ON / OFF of each switch unit, and the number of ON / OFF of each switch unit detected by the detection circuit are integrated. And a display circuit for converting the number of ON / OFF of each switch unit integrated by this integration counter into the number of rotations of the handle and displaying it as a numerical value on the counter display unit. Further, when the switch unit is turned on, it further includes a rotation angle display unit for performing a visible display on a rotation angle of less than one rotation of the handle in conjunction with the switch unit being turned on. ). Here, the device refers to, for example, a load tap switching device of a transformer, and the operation mechanism refers to, for example, an electric operation mechanism of the load tap switching device.

  As a result, when the rotation speed of the rotating shaft rod of the handle includes a rotation speed less than one rotation speed, the rotation angle display section can be visually recognized for a rotation angle of less than one rotation of the handle in conjunction with turning on of the switch section. Since the display is performed, it is possible to detect a rotation speed less than one rotation speed of the handle from the rotation angle of the handle displayed by the rotation angle display section.

  In addition, the counter display unit is provided so as to be radially outward of the rotation shaft rod with respect to the storage unit including the rotation speed detection mechanism and the rotation angle display unit. Compared to the case where the display unit is provided within the rotation range of the arm of the storage unit, the counter display unit is not hidden by the arm, and the number of rotations of the handle displayed on the counter display unit is easy to see.

  In the handle with a rotation angle display unit according to the present invention, the rotation angle display unit has a number and arrangement of lighting units corresponding to the number and arrangement of the switch units on the outer surface of the storage unit. The lighting section is configured to light up when the corresponding switch section is turned on (Claim 2). Here, for example, an LED is used as the lighting section of the rotation angle display section. Here, for example, when the number of switch units is 8, the number of lighting units of the rotation angle display unit is also 8 or a multiple of 8.

  Accordingly, by confirming the position of the illuminating unit that is lit in the rotation angle display unit with respect to the reference point determined at the rotation start position of the handle, a rotation angle of less than one rotation from the reference point of the handle is detected. Accordingly, when the number of lighting parts is eight, it is possible to detect the number of rotations less than one rotation number from 1/8 to 7/8.

  Furthermore, in the handle with a rotation angle display unit according to the present invention, the rotation angle display unit has a reference point for indicating a rotation start position of the handle, and the reference point is centered on the rotating shaft rod. The position can be moved over 360 degrees (Claim 3).

  As a result, since the reference point can be matched with the rotation start position of the handle, the rotation angle display unit with respect to the reference point is lit regardless of the position where the handle rotation starts from the lighting unit of the rotation angle display unit. Since it is possible to detect a rotation angle of less than one rotation from the reference point of the handle only by confirming the position of the lighting section, the number of lighting sections is eight when the number of lighting sections is eight. It is possible to reliably and accurately detect a rotational speed less than one rotational speed from 1 to 7/8.

  On the other hand, the handle with a rotation angle display unit according to the present invention includes a rotation shaft rod attached to the operation mechanism of a device having an operation mechanism operated by an electric motor, and the rotation shaft rod through manual rotation operation. A handle that includes an arm that transmits rotation to the electric motor that is not supplied with electricity, and a storage portion that surrounds the rotating shaft rod from its circumferential direction, and a diameter of the rotating shaft rod that is larger than a rotation range of the arm. A counter display unit provided in the storage unit so as to be outside in the direction, and a rotation number detection mechanism for detecting the rotation number of the rotating shaft rod, the rotation number detection mechanism detecting the position of the handle A position detection sensor and a reference point that is a signal from the position detection sensor are input to determine the rotation start position of the rotary shaft rod, and the rotation speed is detected as 1 rotation when one rotation is made from this reference point. And a display circuit for displaying the rotation number of the handle accumulated in the control unit as a numerical value on the counter display unit, and a plurality of annular members around the rotating shaft rod. The rotation angle display unit further includes a lighting unit. The rotation angle display unit lights up over a range from the reference point to the position of the handle detected by the position detection sensor. A rotation angle of less than one rotation of the handle is displayed (claim 4).

  Thus, by confirming the lighting range of the lighting section of the rotation angle display section from the reference point to the rotational position of the handle, a rotation angle of less than one rotation from the reference point of the handle is detected. It becomes possible to detect the rotation speed less than 1 rotation speed finely.

  Further, the counter display unit is provided on the outer side in the radial direction of the rotating shaft rod with respect to the storage unit provided with the rotation number detection mechanism and the rotation angle display unit, so that the counter display unit is stored in the storage unit. The counter display unit is not hidden by the arm, and the number of rotations of the handle displayed on the counter display unit is easy to see compared to the case where the counter display unit is provided within the rotation range of the arm.

  And any handle | steering-wheel with a rotation angle display part has a power supply for supplying electricity to the said rotation speed detection mechanism and the said rotation angle display part (Claim 5). Here, as the power source, for example, a solar part having a solar panel and the like can be cited.

  Thereby, in order to obtain electricity for driving the counter display unit, the rotation speed detection mechanism, and the rotation angle display unit, there is no need to draw an electric wire or the like from the device to the handle with the rotation angle display unit.

  As described above, according to the inventions according to claims 1 to 3 and claim 5, when the rotational speed of the rotary shaft rod of the handle is less than one rotation, the rotation angle display section is configured with the switch section. The rotation angle of the handle can be visually recognized in conjunction with the turning on of the steering wheel. By checking the rotation angle of the handle using this rotation angle display section, it is possible to detect a rotation speed less than one rotation speed of the handle. Therefore, for example, when it is necessary to know the exact rotational speed of the handle including less than one rotational speed as in the confirmation test after a close inspection of the tap changer at the time of loading of the transformer, Such a handle with a rotation angle display part can be positively used.

  In particular, according to the second aspect of the invention, one rotation from the reference point of the steering wheel is confirmed by confirming the position of the lit lighting part of the rotation angle display part with respect to the reference point determined at the rotation starting position of the steering wheel. A rotation angle of less than 1 is detected with an accuracy obtained by dividing one rotation (360 °) into a plurality of equal parts (8 equal parts), and accordingly, for example, in the case of 8 equal parts, 1/8 Since it is possible to detect the number of rotations of the handle less than one rotation up to 7/8, the number of rotations less than one rotation of the handle can be known more reliably and accurately.

  In particular, according to the third aspect of the present invention, since the reference point can be matched with the rotation start position of the handle, the reference point can be used regardless of the position where the rotation of the handle starts from the lighting portion of the rotation angle display portion. A rotation angle of less than one rotation from the reference point of the handle can be detected simply by confirming the position of the lighting section where the rotation angle display section is lit with respect to the point, and according to this, the number divided equally For example, in the case of eight equal parts, it is possible to detect the number of rotations of the handle less than 1/8 from 1/8 to 7/8. The number of rotations less than one rotation number of the handle can be detected more reliably and accurately.

  Further, according to the invention described in claim 4 and claim 5, by confirming the lighting range of the lighting portion of the rotation angle display portion from the reference point to the rotational position of the handle, one rotation from the reference point of the handle is performed. As a result, a rotational angle of less than one rotational speed of the handle can be detected in detail, so that, for example, a confirmation test after a close inspection of a tap switching device when a transformer is loaded When it is necessary to know the exact number of rotations of the handle including less than one rotation number, the handle with the rotation angle display unit according to the present invention can be used more actively.

  According to the fifth aspect of the present invention, in order to obtain electricity for driving the counter display unit, the rotation speed detection mechanism, and the rotation angle display unit, an electric wire or the like is drawn from the device to the handle with the rotation angle display unit. Since it becomes unnecessary, it is possible to prevent the configuration of the handle with the rotation angle display unit from becoming complicated.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows an example of an LTC switching operation monitoring device in which a handle with a rotation angle display unit (hereinafter referred to as a handle) 12 according to the present invention is used. The LTC switching operation monitoring device includes an on-load tap switching device 1, an electric motor 2 that drives the on-load tap switching device 1, a shaft torque sensor 3 attached to the electric shaft of the electric motor 2, and the driving force of the electric motor 2. And a bevel gear mechanism 4 for transmitting to the tap switching device 1 when loaded.

  Among these, the on-load tap switching device 1 is assembled to the transformer 5, and the tap selector 1a and the converter 1b housed in the tank 5a of the transformer 5 and a part thereof are housed in the tank 5a. The other part is comprised with the switching switch 1c which protruded from the upper surface of the tank 5a. The switching switch 1c of the on-load tap changer 1 and one bevel gear 4a of the bevel gear mechanism 4 are connected by a laterally connected drive shaft rod 6, and the other bevel gear 4b of the bevel gear mechanism 4 and the electric motor 2 are shafts. They are connected by a longitudinally connected drive shaft rod 7 extending from the torque sensor 3.

  The electric motor 2 is for electrically operating the on-load tap switching device 1 via the longitudinally connected drive shaft rod 7, the bevel gear mechanism 4, and the laterally connected drive shaft rod 6, and this electric motor 2 and a handle mounting mechanism 10 described below. The shaft rod 10a is housed in a case 9 disposed outside the tank 5a of the transformer 5 together with a speed reduction mechanism 8 for reducing the rotation of the shaft rod 10a to a rotation speed suitable for driving the on-load tap switching device 1. ing.

  In this embodiment, the handle mounting mechanism 10 is provided with a shaft rod 10a and a tip of the shaft rod 10a, to which a rotating shaft rod 13 of the handle 12 according to the first or second embodiment described below is mounted. Part 10b.

  As shown in FIG. 2, the handle 12 according to the first embodiment is inserted into the mounting portion 10 b of the handle mounting mechanism 10 to rotate integrally with the shaft 10 a of the handle mounting mechanism 10. And a rod-like arm 14 that transmits the rotation to the shaft rod 10a of the electric motor 2 through the rotation shaft rod 13 by rotating. The arm 14 has a grip portion 14a extending in the radial direction of the arm 14 at the tip thereof.

  The rotary shaft 13 of the handle 12 is surrounded by a substantially cylindrical storage portion 15 having a hollow inside from the circumferential direction thereof, and the bearing portion 16 stored in the storage portion 15 allows the rotation of the storage portion 15. It is rotatably held on the inner surface. That is, even if the handle | steering-wheel 12 is rotated, the accommodating part 15 does not rotate with the rotating shaft rod 13, but is a thing which does not move.

  Further, a box 17 is provided outside the storage unit 15 in the radial direction of the rotary shaft 13, and the box 17 includes a counter display unit 18 that displays the number of rotations of the handle 12 in units of one rotation number, A reset button 19 is arranged. The counter display unit 18 may be a digital display or an analog display.

  Incidentally, the handle 12 has a rotation speed detection mechanism 21 that detects the rotation speed of the handle 12 one by one. As shown in FIGS. 2 and 3, the rotational speed detection mechanism 21 includes a protrusion 22 that protrudes in the radial direction of the rotary shaft 13 from the side surface of the portion of the rotary shaft 13 that is located in the storage portion 15. Are arranged at equal intervals (45 ° intervals in this embodiment 1) on the circumference along the rotation trajectory of the projection 22 in the storage unit 15, and are turned ON / OFF by contact with the projection 22. Eight switch units 23, a switch unit ON / OFF detection circuit 24 that detects ON / OFF of each switch unit 23, an integration counter 25 that integrates the number of ON / OFF times of the switch unit 23, and a handle for the integrated value A counter display circuit 26 for converting the number of revolutions to 12 and displaying the numerical value on the counter display unit 18, the reset button 19, and a reset for resetting the integration counter 25 when the reset button 19 is pressed. And a circuit 27. Note that the number of the switch parts 23 is not limited to eight, and can be freely determined according to the use and necessity as long as they are arranged at equal intervals.

  The switch portion 23 has a protrusion 23a that can protrude and retract from the main body portion 23b. The rotation shaft rod 13 rotates, and the protrusion 22 of the rotation shaft rod 13 pushes the protrusion 23a of the switch portion 23. The switch portion 23 is turned on by immersing the switch portion 23 into the ON state, the protrusion portion 22 of the rotary shaft 13 is separated from the protrusion portion 23a of the switch portion 23, and the protrusion portion 23a returns from the state of being immersed in the main body portion 23b. The switch unit 23 is turned off. However, the present invention is not limited to this configuration. When the projection 22 of the rotary shaft 13 and the projection 23a of the switch portion 23 come into contact with each other, power is supplied, and the projection 22 of the rotary shaft 13 is projected to the projection 23a of the switch portion 23. The switch unit 23 may be turned on / off by being cut off when it is separated from the switch.

  As a result, as the rotary shaft 13 rotates, the protrusions 22 sequentially press and release the switch parts 23 protrusions 23a, so that the ON / OFF of the switch parts 23 is also in turn. When the integrated value in the ON / OFF integration counter 25 of each switch unit 23 detected by the switch unit ON / OFF detection circuit 24 matches the total number 8 of the switch units 23, the handle 12 is rotated once. Therefore, the counter display circuit 26 converts the rotation number to 1, and the display on the counter display unit 18 is incremented. On the other hand, when the number of rotations of the handle 12 is counted again, if the reset button 19 is pressed, the integration counter 25 is reset, and this is transmitted to the counter display unit 18 via the counter display circuit 26, and the counter display unit. The display of 18 is set to 0.

  Further, as shown in FIG. 2, the handle 12 has a rotation angle display unit 29 for displaying a rotation angle of the handle 12 less than one rotation. The rotation angle display unit 29 pays attention to ON / OFF of the switch unit 23, and is disposed on the opposite side of the storage unit 15 from the handle mounting mechanism 10, and in the circumferential direction corresponding to the number of the switch units 23. It is composed of eight LEDs 30 arranged at intervals (45 ° intervals in this embodiment 1) and a reference point 31 for indicating the rotation start position of the rotation angle display section. That is, the protrusion 22 of the rotary shaft 13 and each switch unit 23 are also configured as a rotation angle display unit 29. In the first embodiment, an annular plate 32 having a reference point 31 is attached to the storage portion 15 so as to be rotatable about the rotary shaft 13 as a center point. The number of LEDs 30 is not limited to eight as in the case of the switch unit 23, and may not be the same as the number of the switch units 23, and can be freely determined according to the use and necessity.

  In the first embodiment, the solar unit 33 is provided in the box 17 as a power source for supplying electricity to the rotation speed detection mechanism 21 and the rotation angle display unit 29, particularly the light emitted from the LED 30. This eliminates the need for the handle 12 to be supplied with electricity from an external device such as an LTC switching operation monitoring device.

With this configuration, when the handle 12 is manually rotated with the arm 14, the protrusion 22 of the rotary shaft 13 is pressed against the protrusion 23 a of the switch portion 23. Since the LED 30 corresponding to the switch portion 23 on which the portion 23a is pressed emits light, the rotation angle of the handle 12 from the reference point 31 is detected by 45 ° by checking the position of the LED 30 from the reference point 31. Accordingly, for the rotation of the handle 12 less than 1 rotation, 1/8 rotation, 2/8 rotation, 3/8 rotation, 4/8 rotation, 5/8 rotation, 6/8 rotation, and As 1/8 rotation, 1/8 rotation can be detected. In addition, since the position of the reference point 31 can be changed by rotating the plate 32, even if the position of the arm 14 starts to rotate from a position other than the position where the arm 14 is lowered along the vertical direction, for example, the reference position is the reference position. Since adjustment can be made so that the point 31 comes, rotation of the handle 12 less than one rotation can be accurately detected.

  As shown in FIG. 4, the handle 12 according to the second embodiment includes a rotary shaft 13, an arm 14, a storage unit 15 that surrounds the rotary shaft 13 in the circumferential direction, a counter display unit 18, and a reset button 19. In addition, the second embodiment is the same as the first embodiment in that the box 17 is provided with the solar section 33. However, the rotation speed detection mechanism 21 for detecting the rotation speed of the handle 12 one by one and the handle 12 are provided. The structure of the rotation angle display unit 29 that displays a rotation angle less than the rotation is different from that of the first embodiment. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is basically omitted.

  As shown in FIGS. 4 and 5, the rotation speed detection mechanism 21 detects a position detection sensor 36 that detects the position of the handle 12, an output signal from the position detection sensor 36, and when the reset button 19 is pressed. The control unit 37 for integrating the rotation number of the handle 12 in units of one rotation number and the counter display circuit 26 for displaying the accumulated rotation number of the handle 12 on the counter display unit 18 as numerical values. ing.

  Further, the rotation angle display unit 29 includes, for example, a divided LED 40 divided into 16 pieces, an LED driving circuit 41 for individually lighting the divided LEDs 40, and four reference points 31a, 31b, 31c, 31d. The position detection sensor 36 and the control unit 37 described in relation to the rotation speed detection mechanism 21 also function as components of the rotation angle display unit 29. The divided LED 40 can select and light one of two different colors such as blue or red.

  In such a configuration, the control unit 42 performs control according to the flow shown in FIG. That is, it is determined in step 101 whether or not the reset button 19 has been pressed. If the reset button 19 has not been pressed, the process proceeds to step 102 where the position detection sensor 36 detects the position of the handle 12 and The divided LEDs 40 are sequentially turned on from any one of the reference points 31a to 31d in accordance with the position of. Next, in step 104, it is determined whether or not the handle 12 has made one rotation starting from the reference points 31a to 31d. If the handle 12 has made one rotation, the display on the counter display unit 18 is incremented. Returns to step 101. If the display on the counter display unit 18 is incremented in step 105, the display of the divided LED 40 is reset (turned off) in step 106, and the process returns to step 101.

  On the other hand, if it is determined in step 101 that the reset button 19 has been pressed, the process proceeds to step 107 to reset the display on the counter display unit 18, and further proceeds to step 108 to reset the display of the divided LED 40 ( Off). Thereafter, the process proceeds to step 109, where the position detection sensor 36 detects the position of the handle 12, and in step 110, the reference points 31a to 31d are selected, and the divided LEDs 40 close to the selected reference points 31a to 31d are set to a predetermined color. (For example, if the color of the divided LED 40 to be lit in step 103 is blue, the color is easily distinguishable such as red if the color is blue), and then the process returns to step 101.

  As a result, the rotation angle display unit 29 causes the divided LEDs 40 close to the reference points 31a to 31d selected based on the position of the handle 12 detected by the position detection sensor 36 to emit light in a predetermined color, and rotates the handle 12. The divided LED 40 that follows the divided LED 40 positioned at the reference point 31 that emits light in the predetermined color (for example, red) is sequentially lit in a different color (for example, blue) from the divided LED 40 that is positioned at the reference point 31. By confirming the lighting range of the LED 40, it is possible to detect the rotation angle of the handle 12 less than one rotation, and accordingly, to detect the rotation number of the handle 12 less than one rotation. Since the color of the divided LED 40 that is lit at the point 31 is different from the color of the other divided LED 40 that is lit, the reference point 31 can be confirmed immediately. . In addition, since the rotation angle of the handle 12 can be displayed more finely than the first embodiment in which the rotation angle of the handle 12 is displayed by 1/8 each, the number of rotations of the handle 12 less than one rotation can be detected. Accuracy is also improved.
