DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a voltage detector check support tool according to the present invention will be described in detail below with reference to the accompanying drawings.

<Embodiment 1>
(Configuration of voltage detector check support tool)
First, the configuration of a voltage detector check support tool according to Embodiment 1 of the present invention will be described. FIG. 1 is an explanatory diagram showing the configuration of a voltage detector check support tool according to Embodiment 1 of the present invention.

In FIG. 1, a voltage detector check support tool 100 according to Embodiment 1 of the present invention comprises a connecting portion 110 and a connecting portion 120. As shown in FIG. The connecting portion 110 has a ring shape with a through hole 111 . The inner diameter D1 of the through hole 111 is substantially the same as the outer diameter of the detector in the windmill type voltage detector. The inner diameter dimension D1 of the through hole 111 is preferably slightly larger than the outer diameter dimension of the detector in the windmill type voltage detector.

Specifically, the inner diameter dimension D1 of the through hole 111 is such that when an external force rotating around the axis of the detector of the windmill voltage detector is applied to the connection portion 110, the detection The dimensions are set so that it can rotate around the axis while at least a portion of the element is in contact with the element. The windmill voltage detector will be described later (see FIG. 2).

The connecting portion 110 is made of a material exhibiting conductivity. The connecting portion 110 can be formed, for example, by winding a wire-like member obtained by extending a thin wire of metal into an annular shape. The wire-like member has a circular cross-sectional shape perpendicular to the length direction. The cross-sectional shape of the wire-like member may be a perfect circle or an ellipse.

Also, the connecting portion 110 can be formed by winding a wire-like member made of a metal material exhibiting good conductivity, such as copper, iron, aluminum, etc., in a ring shape. The connecting portion 110 may be formed of, for example, an iron wire-like member having a surface plated with galvanized conductive material. By forming the connection part 110 with such a wire-like member made of iron whose surface is galvanized, it is possible to suppress an increase in electrical resistance caused by rusting of the surface like iron.

The connection portion 110 is formed by winding a wire-like member in two or more loops. Specifically, the connecting portion 110 is such that, for example, the dimension of the through hole 111 in the axial direction is larger than the outer dimension of the wire-shaped member, and the detection by the windmill voltage detector It is formed by winding a wire-like member into an annular shape with the number of turns smaller than the dimension in the axial direction of the child.

The connecting portion 120 is made of a conductive material and has a rod shape. The connecting portion 120 is connected to the connecting portion 110 at one end in the length direction. The connecting portion 120 is electrically connected to the connecting portion 110 . In the first embodiment, an example in which connecting portion 110 and connecting portion 120 are electrically directly connected has been described, but connecting portion 110 and connecting portion 120 are electrically connected via a conductive member. may have been

The connecting portion 120 protrudes from one end connected to the connecting portion 110 in the outer peripheral direction of the ring formed by the connecting portion 110 . As a result, the length direction of the connecting portion 120 is parallel to the radial direction of the through hole 111 in the connecting portion 110, and the other end in the length direction of the connecting portion 120 is positioned away from the outer peripheral surface of the connecting portion 110. is positioned in

The connecting portion 120 in the voltage detector check assisting tool 100 of Embodiment 1 is formed by twisting both end portions of the wire-like member forming the connecting portion 110 . Thus, the connecting portion 110 and the connecting portion 120 are formed using an integral wire-like member.

The connection part 120 in the voltage detector check assisting tool 100 of the first embodiment is twisted to form a columnar shape. The outer dimension of the connecting portion 120 twisted to form a columnar shape, that is, the span dimension D1 of the connecting portion 120 is smaller than the outer diameter dimension in the axial direction of the detector in the windmill voltage detector.

In addition, the span dimension D2 of the connecting portion 120 is smaller than the maximum opening width of the alligator clip that realizes the terminals of the voltage detector checker. The voltage detector checker will be described later (see FIGS. 3-6). The connecting part 120 may have a shape in which at least a part of the span dimension D2 (outer diameter dimension) in the length direction is smaller than the maximum opening width of the alligator clip that realizes the terminal of the voltage detector checker. .

Specifically, the connecting portion 120 may have, for example, a narrowed shape such that a part of the lengthwise span dimension D2 is partially smaller than the circumference. Alternatively, specifically, the connecting portion 120 may have a plate-like compressed shape such that a part of the connecting portion 120, for example, has a span dimension D2 in the length direction that is partially smaller than the circumference.

(Configuration of windmill type voltage detector)
Next, a description will be given of the configuration of a windmill-type voltage detector to be subjected to voltage detector check work using the voltage detector check support tool 100 according to the first embodiment of the present invention. FIG. 2 is an explanatory diagram showing the configuration of the windmill type voltage detector.

As shown in FIG. 2 , the windmill voltage detector 200 includes an insulating rod 210 and a detector 220 . The insulating rod 210 has a rod shape and is formed using a material exhibiting insulation. The insulating rod 210 is realized by a hollow cylindrical member, and a capacitor (not shown) is accommodated inside the insulating rod 210 .

The insulating rod 210 may have an extendable telescopic structure in which a plurality of cylindrical members are concentrically stacked. When the insulating rod 210 has a telescopic structure, the capacitor is housed inside the innermost cylindrical member. The insulating rod 210 is provided with a belt 211 that is put on the shoulder of the operator when the windmill type voltage detector 200 is transported.

The detection unit 220 includes a case 222 that accommodates the windmill 221 , and electrodes 223 and detectors 224 provided on the case 222 . Electrode 223 is connected to a capacitor. The case 222 is formed using an optically transparent material, and the inside of the case 222 can be visually recognized. The windmill 221 is supported by a shaft 221a fixed inside the case 222 so as to be rotatable around the shaft.

The electrode 223 is provided on the insulating rod 210 side of the case 222 , and the detector 224 is provided on the opposite side of the case 222 from the insulating rod 210 . The electrode 223 and the detector 224 face each other with the windmill 221 interposed therebetween. The detector 224 has, for example, a substantially cylindrical shape. Alternatively, the detector 224 may have a shape that is sharper toward the tip.

The windmill type voltage detector 200 rotates the windmill 221 using corona wind generated by corona discharge, which is a continuous discharge caused by a non-uniform electric field generated around the detector 224 . During voltage detector checking work for checking the operation of the windmill type voltage detector 200, corona discharge is generated by applying a voltage to the detector 224, and the windmill 221 is rotated by the corona wind generated in the case 222 by this corona discharge. . By rotating the windmill 221 while voltage is applied, it can be confirmed that the windmill voltage detector 200 is operating normally.

(Example of voltage detector check work)
Next, an example of voltage detector check work using the voltage detector check support tool 100 of Embodiment 1 according to the present invention will be described. 3 to 7 are explanatory diagrams showing an example of voltage detector check work using the voltage detector check support tool 100 according to the first embodiment of the present invention.

In the voltage detector check work using the voltage detector check support tool 100 of Embodiment 1 according to the present invention, first, the voltage detector check support tool 100 is attached to the windmill type voltage detector 200 . Specifically, as shown in FIG. 3 , the detector 224 of the windmill type voltage detector 200 is fitted into the through hole 111 in the connecting portion 110 of the voltage detector check support tool 100 .

As described above, the inner diameter dimension D1 of the through hole 111 is formed slightly larger than the outer diameter dimension D3 of the detector 224, so that the connection portion 110 is subjected to an external force rotating around the axis of the detector 224. In this case, according to the external force, it can rotate about the axis while at least a part of the inner circumference is in contact with the detector 224 .

Alternatively, when the windmill type voltage detector 200 having a detector 224 with a sharp tip is targeted for the voltage detector check work, the inner diameter D1 of the through hole 111 in the voltage detector check support tool 100 is It is formed slightly larger than the outer diameter dimension D3, which is the largest. Accordingly, when an external force rotating around the axis of the detector 224 is applied, the connecting part 110 is in a state in which at least a part of the inner circumference is in contact with the detector 224 in response to the external force. can be rotated around the axis.

Also, the terminal 301 of the voltage detector checker 300 is connected to the connecting portion 120 of the voltage detector check support tool 100 . The voltage detector checker 300 has a housing 302 made of resin. A power source such as a dry battery and an electronic circuit are provided in the housing 302 (not shown). A terminal 301 of the voltage detector checker 300 is realized by an alligator clip provided at the other end of a lead wire (high voltage lead wire) 303, one end of which is connected to an electronic circuit.

The electronic circuit consists of a sine wave oscillator circuit that oscillates a sine wave, an amplifier circuit that amplifies the sine wave generated by the sine wave oscillator circuit, and a step-up transformer that further boosts the sine wave amplified by the amplifier circuit. . A switch 304 is provided in the housing 301 and connects and disconnects the electric circuit according to the operation. When the electric circuit is connected in response to the operation of the switch 304, the voltage detector checker 300 supplies power to the electric circuit and outputs a high voltage for checking operation from the terminal.

In the voltage detector check operation using the voltage detector check support tool 100 of Embodiment 1 according to the present invention, the connecting portion 120 is clamped by the alligator clip, which is the terminal 301 of the voltage detector checker 300, so that the connecting portion The terminal 301 of the voltage detector checker 300 is connected to 120 . As a result, the windmill voltage detector 200 and the voltage detector checker 300 can be electrically connected without directly connecting the windmill voltage detector 200 and the voltage detector checker 300 .

Next, the switch 304 of the voltage detector checker 300 is operated to apply a voltage to the detector 224 of the windmill type voltage detector 200, and the presence or absence of rotation of the windmill 221 is visually confirmed. Whether or not the wind turbine 221 rotates is checked in each posture by placing the wind turbine voltage detector 200 in a plurality of postures. As a result, problems such as the windmill 221 not rotating in a specific posture due to the weight of the windmill 221, interference between the blades and the shaft of the windmill 221, and the like can be avoided.

Specifically, for example, as shown in FIG. 4 , in a posture in which the detector 224 is positioned vertically above the wind turbine 221 , the wind turbine voltage detector 200 is moved to the axial center of the detector 224 as indicated by an arrow 400 . The presence or absence of rotation of the windmill 221 is confirmed while rotating it around. In the voltage detector check support tool 100, since the connecting portion 120 protrudes in the outer peripheral direction of the ring formed by the connecting portion 110, the dead weight of the connecting portion 120 and the terminal 301 of the voltage detector checker 300 connected to the connecting portion 120 Due to the weight of the lead wire 303 , the protruding position of the connecting portion 120 around the axis of the through hole 111 is locally heavy.

For this reason, in the state shown in FIG. 4 , the voltage detector check support tool 100 detects the A force that pulls the connecting portion 120 side from the child 224 downward in the vertical direction acts. In the state shown in FIG. 4, since the windmill 221 is positioned below the detector 224 in the vertical direction, the voltage detector check support tool 100 can A part of the weight of is supported by the case 222, and the windmill voltage detector 200 can be stably rotated.

As described above, the inner diameter dimension D1 of the through-hole 111 is such that when an external force rotating around the axis of the detector 224 is applied to the connecting portion 110, the detector 224 is affected by the external force. The position of the voltage detector check support tool 100 is constant when the windmill type voltage detector 200 is rotated. While the detector 224 is slid in the through hole 111, only the windmill type voltage detector 200 rotates.

As a result, the operator can rotate the windmill voltage detector 200 with one hand while rotating the voltage detector 300 with the other hand without performing troublesome work such as moving the position of the voltage detector checker 300 according to the rotation of the windmill voltage detector 200 . By simply holding the voltage detector checker 300 and operating the switch 304, it is possible to easily check whether or not the windmill 221 is rotating.

Specifically, for example, as shown in FIG. The presence or absence of rotation of the windmill 221 is confirmed while rotating around the center. In the voltage detector check support tool 100, as described above, since the connection portion 120 protrudes in the outer peripheral direction of the ring formed by the connection portion 110, the dead weight of the connection portion 120 and the voltage detector checker connected to the connection portion 120 Due to the weight of terminal 301 and lead wire 303 of 300 , the protruding position of connecting portion 120 is locally heavy around the axis of through hole 111 .

For this reason, in the state shown in FIG. A force that pulls the connecting portion 120 side from the child 224 downward in the vertical direction acts. In the state shown in FIG. 5 , of the peripheral edge of the through hole 111 in the connecting portion 110 , the peripheral edge on the side opposite to the coupling portion 120 with the detector 224 therebetween is vertically moved upward by the weight of the coupling portion 120 . pressed against.

Since the connecting portion 110 is pressed against the detector 224 in this manner, friction is generated between the connecting portion 110 and the detector 224, and the frictional force fixes the position of the connecting portion 110 with respect to the detector 224. , the windmill-type voltage detector 200 can be stably rotated in a state in which the windmill-type voltage detector 200 and the voltage detector checker 300 are electrically connected. At this time as well, the operator rotates the windmill type voltage detector 200 with one hand, holds the voltage detector checker 300 with the other hand, and operates the switch 304 in the same manner as described above. The presence or absence can be easily confirmed.

Specifically, for example, as shown in FIG. 6, in a posture in which the detector 224 is located vertically below the wind turbine 221, the wind turbine voltage detector 200 is moved to the detector 224 as indicated by an arrow 600. The presence or absence of rotation of the windmill 221 is confirmed while rotating it around the axis of . In the voltage detector check support tool 100, as described above, the connecting portion 120 protrudes in the outer peripheral direction of the ring formed by the connecting portion 110. Therefore, as shown in FIG. Due to the weight w2 of the terminal 301 and the lead wire 303 of the voltage detector checker 300 connected to the portion 120, the protruding position of the connecting portion 120 is locally heavy around the axis of the through hole 111. , 602 is applied.

Therefore, the opening surface of the through hole 111 indicated by the dotted line 603 in FIG. In contrast, the axial direction of the through hole 111 is inclined. As a result, of the peripheral edge of the through hole 111 in the connecting portion 110, the peripheral edge on the side opposite to the connecting portion 120 with the detector 224 therebetween and the upper side in the vertical direction and the connecting portion 120 side of the detector 224 7, the dead weight w1 of the connecting portion 120 and the weight w2 of the terminal 301 and the lead wire 303 of the voltage detector checker 300 connected to the connecting portion 120. is pressed against the detector 224 by .

Friction is generated between the connecting portion 110 and the detecting element 224 by pressing the peripheral edge of the through hole 111 in the connecting portion 110 against the detecting element 224 in this way, and the frictional force causes the connecting portion 110 to contact the detecting element 224 . position can be fixed. As a result, even when the detector 224 is positioned below the windmill 221 in the windmill type voltage detector 200 in the vertical direction, the voltage detector check support tool 100 does not drop off from the detector 224. The windmill type voltage detector 200 can be stably rotated while the voltage detector checker 300 is electrically connected to the voltage detector 200 .

At this time as well, the operator rotates the windmill type voltage detector 200 with one hand, holds the voltage detector checker 300 with the other hand, and operates the switch 304 in the same manner as described above. The presence or absence can be easily confirmed.

In the first embodiment described above, connection portion 110 may be formed using, for example, a wire-like member made of iron having a zinc-plated surface and subjected to chromate treatment. Chromate treatment is performed by immersing an iron wire-like member having a zinc-plated surface in a chromate solution (chromate treatment solution) in which chromate that passivates metal is dissolved.

By performing the chromate treatment, a passivated metal layer (chromate coating) can be formed on the surface of the iron wire-like member having the zinc-plated surface. Since the chromate film is an oxide film having self-healing properties, the rust prevention of the connection portion 110 can be improved by forming the connection portion 110 using a wire-like member subjected to chromate treatment.

When connecting portion 110 is formed using a chromate-treated wire-like member, the chromate coating is removed from the inner periphery of through hole 111 formed by the annularly wound wire-like member. Specifically, the chromate film on the inner periphery of the ring is removed by polishing the inner peripheral surface of the wire-like member wound into a ring.

In addition, when connecting portion 110 and connecting portion 120 are formed using a chromate-treated wire-like member, the chromate coating on at least a portion of connecting portion 120 is removed. Specifically, for example, the chromate coating is removed from the end of the connecting portion 120 (the end opposite to the connecting portion 110) to expose the zinc plating. Alternatively, the formation of the chromate film on the connecting portion 120 is inhibited by masking the position of the connecting portion 120 during the chromate treatment of the zinc-plated iron wire-like member. Accordingly, it is possible to ensure the corrosion resistance of the connecting portion 110 by providing the chromate coating, and also to ensure the electrical conductivity of the connecting portion 120 .

As described above, the voltage detector check support tool 100 of Embodiment 1 according to the present invention has a ring shape with the through hole 111 that can be fitted to the root portion of the detector 224 in the windmill type voltage detector 200. , a connecting portion 110 formed of a material exhibiting conductivity, one end of which is electrically connected to the connecting portion 110, and protrudes from the one end in the outer peripheral direction of the ring formed by the connecting portion 110, extending from the one end to the other end. and a connecting portion 120 formed of a material exhibiting conductivity and having a rod shape in which at least a part of the span dimension D2 is smaller than the outer diameter dimension of the detector 224 .

According to the voltage detector check support tool 100 of Embodiment 1 according to the present invention, the connecting portion By connecting the terminal 301 of the voltage detector checker 300 to the other end of the voltage detector 120, the wind turbine voltage detector 200 and the voltage detector checker 300 can be electrically connected without directly connecting the wind turbine voltage detector 200 and the voltage detector checker 300. can be connected to

In the voltage detector check support tool 100 of Embodiment 1 according to the present invention, at least a part of the span dimension D2 from one end to the other end of the connecting part 120 is smaller than the outer diameter dimension of the detector 224. Since the terminal 301 of the voltage detector checker 300 has a bar shape, even if the terminal 301 of the voltage detector checker 300 is realized by an alligator clip or the like having a limited opening width, even if the terminal cannot be directly connected to the detector 224, the crossover dimension The portion where D2 is small can be clamped with an alligator clip, and the windmill voltage detector 200 and the voltage detector checker 300 can be electrically connected.

Further, according to the voltage detector check support tool 100 of Embodiment 1 according to the present invention, since the connecting portion 120 protrudes in the outer peripheral direction of the ring formed by the connecting portion 110, the connecting portion around the axis of the through hole 111 The protruding position of 120 is locally heavy due to the self weight of connecting part 120 . Therefore, when the base of the detector 224 of the windmill voltage detector 200 is fitted into the through-hole 111 of the connecting portion 110, the weight of the connecting portion 120 causes the connecting portion 120 side of the detector 224 to move in the vertical direction. A downward pulling force acts.

As a result, for example, when the windmill voltage detector 200 is in a posture in which the axial direction of the detector 224 is substantially parallel to the vertical direction, the axial direction of the through hole 111 with respect to the axial direction of the detector 224 of the peripheral edge of the through hole 111 in the connecting portion 110, the peripheral edge on the side opposite to the coupling portion 120 with the detector 224 therebetween and the upper peripheral edge in the vertical direction and the detector 224 on the connecting part 120 side and vertically lower peripheral edge is pressed against the detector 224 by the dead weight of the connecting part 120 .

By pressing the connecting portion 110 against the detector 224 in this manner, friction is generated between the connecting portion 110 and the detector 224 , and the frictional force fixes the position of the connecting portion 110 with respect to the detector 224 . As a result, even when the detector 224 is positioned below the windmill 221 in the windmill voltage detector 200 in the vertical direction, the voltage detector check support tool 100 does not drop off from the detector 224. 200 and electroscope checker 300 can be electrically connected.

Further, for example, when the windmill voltage detector 200 is in a posture in which the axial direction of the detector 224 is substantially parallel to the horizontal direction, the axial direction of the detector 224 and the axial direction of the through hole 111 are substantially parallel. Perpendicularly, of the peripheral edge of the through hole 111 in the connecting portion 110, the peripheral edge on the side opposite to the connecting portion 120 with the detector 224 therebetween is pressed against the detector 224 from the vertical direction upper side by the weight of the connecting portion 120. be done. By pressing the connecting portion 110 against the detector 224 in this manner, friction is generated between the connecting portion 110 and the detector 224 , and the frictional force fixes the position of the connecting portion 110 with respect to the detector 224 .

As a result, in the voltage detector check work for confirming the operation of the windmill type voltage detector 200, the windmill type voltage detector 200 is rotated around the axis of the detector 224, or the direction of the axis of the detector 224 is changed.
