Description

Technical Field

[0001] This invention relates to an inlet / outlet position detection device and an inlet / outlet monitoring system having the device, and more specifically, to an inlet / outlet position detection device for power equipment capable of linearly detecting the inlet / outlet position of the circuit breaker body on a support and an inlet / outlet monitoring system having the device. Background Technology

[0002] A circuit breaker is a device that disconnects a circuit to protect the load and power supply in the event of an abnormal or fault current.

[0003] Air circuit breakers are a type of circuit breaker that interrupts current in the event of a load being switched on or off in a power transmission, substation, or circuit, or in the event of a grounding or short circuit fault. They are mainly used in low-voltage equipment.

[0004] The circuit breaker is equipped with a bracket to facilitate the inspection, use, or replacement of the circuit breaker body.

[0005] Circuit breakers can be classified into fixed type circuit breakers, where the circuit breaker body is fixed to the bracket, and drawable type circuit breakers, where the circuit breaker body can be drawn in and drawn out of the bracket.

[0006] In the case of the lead-out type circuit breaker, the circuit breaker body is led into the bracket in order to conduct current. In this led-out state, the circuit breaker will perform on and off operations. If a fault current occurs in the line while the circuit breaker is in the on state, the circuit breaker will interrupt the fault current after a predetermined time or immediately, depending on the magnitude of the fault current.

[0007] Figure 1 A structural diagram representing existing electrical equipment is shown.

[0008] Reference Figure 1 The existing power equipment 10 includes: a circuit breaker body 13; a bracket 11, the circuit breaker body 13 being located inside the bracket 11 and movable; a handle insertion part 15 for inserting a handle 17; and a handle 17, which is inserted into the handle insertion part 15 and rotated to move the circuit breaker body 13 to a discontinuous position, a test position, a connected position, etc.

[0009] Therefore, if the handle 17 is inserted into the handle insertion part 15 and rotated while the circuit breaker body 13 is inside the bracket 11, the circuit breaker body 13 will be in any of the following positions within the bracket 11: lead-out position, test position, or lead-in position.

[0010] Figure 2 This is a front view showing the location display device installed on another existing power equipment.

[0011] Reference Figure 2 The existing power equipment includes a location display device 30. Thus, the location of the power equipment is displayed externally via the location display device 30.

[0012] However, in the existing power equipment position display device 30, the handle insertion part 33 is located above the indicator 31. Therefore, when adjusting the position of the circuit breaker body 13 using the handle 17, there is a problem that the indicator 31 is blocked by the handle 17, making it difficult to accurately determine the current position of the circuit breaker body 13.

[0013] Of course, as mentioned above, although the indicator is positioned above the handle insertion part by converting the rotational motion of the worm gear into linear motion, this can only be confirmed when the circuit breaker body 13 is in any of the following positions within the bracket 11: lead-out position, test position, or lead-in position.

[0014] Therefore, the problem with the existing technology is that it is actually difficult to achieve linear position detection during the movement of the circuit breaker body to any of the lead-out position, test position, or lead-in position in the bracket.

[0015] The patent document related to this invention is Korean Patent No. 10-1151940. Summary of the Invention

[0042] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily implement the invention.

[0043] This invention can be implemented in various different forms and is not limited to the embodiments described herein.

[0044] To clearly illustrate the invention, irrelevant parts have been omitted, and the same or similar reference numerals are used for the same or similar components throughout the specification.

[0045] In the following text, "arbitrary configuration provided or arranged on the "upper (or lower)" or "on (or below)" of the substrate means that any configuration is provided or arranged in contact with the top (or bottom) surface of the substrate.

[0046] In addition, it is not limited to other configurations between the substrate and any configuration disposed or configured on (or under) the substrate.

[0047] Hereinafter, the power equipment lead-in / lead-out position detection device and the lead-in / lead-out monitoring system having the device will be described with reference to the accompanying drawings.

[0048] Figure 3 This is a perspective view showing the connection between the bracket and the circuit breaker body of the present invention. Figure 4 This is a perspective view showing the state in which the circuit breaker body according to the present invention is inserted into the insertion space of the bracket. Figure 5 This is a diagram showing a first example of a position detection member in a position detection unit of the present invention. Figure 6 This is a diagram illustrating a second example of the position detection component of the present invention.

[0049] Reference Figure 3 The lead-out position detection device of the present invention includes a bracket 100, a circuit breaker body 200, and a position detection unit 300.

[0050] An insertion space is formed inside the bracket 100 of the present invention. The bracket 100 has a front opening. The insertion space is the space for introducing the circuit breaker body 200.

[0051] Depending on the position moved by the circuit breaker body 200, one of the following positions—outlet position, test position, and inlet position—is preset in the insertion space. The distance between these three positions is preset and referred to as the movement distance.

[0052] Guide plates 210 are respectively arranged on both sides of the bracket 100. A circuit breaker body 200 is mounted on the bracket 100. The guide plates 210 are movably configured within the configuration space formed inside the bracket 100. Therefore, since the circuit breaker body 200 is mounted on the guide plates 210, the movement of the guide plates 210 refers to the movement of the circuit breaker body 200.

[0053] The guide plate 210 has a predetermined length in the horizontal direction and a predetermined width in the vertical direction.

[0054] In addition, guide holes 110 with a predetermined length in the horizontal direction are cut open on both sides of the bracket 100.

[0055] The guide hole 110 is cut to a length corresponding to the aforementioned moving distance.

[0056] Furthermore, the outer surface of the guide plate 210 can be exposed to the outside through the guide hole 110.

[0057] As a result, a portion of the outer surface of the guide plate 210 is exposed to the outside through the guide hole 110.

[0058] Here, a portion of the outer surface of the guide plate 210 exposed through the guide hole 110 is referred to as the setting area.

[0059] The position detection unit 300 of the present invention linearly detects the movement position of the guide plate 210, on which the circuit breaker body 200 is mounted, during the introduction and exit of the configuration space of the bracket 100.

[0060] The position detection unit 300 includes a position detection component 310 and an optical sensor 320.

[0061] The position detection component 310 is attached to the aforementioned location. The attachment method can be a bolt-on connection or an adhesive attachment.

[0062] Reference Figure 5 The position detection component 310 of the present invention is attached to a predetermined area exposed by the guide hole 110 on the side of the guide plate 210. The position detection component 310 has a reflective region 311 that reflects different amounts of light along its length.

[0063] The position detection component 310 is attached to a setting area formed on the side of the guide plate 210.

[0064] The optical sensor 320 is disposed on the bracket 100 in a manner that is near the guide hole 110, and measures the movement position of the circuit breaker body 200 by emitting light into the reflective area of ​​the position detection member 310 and measuring the amount of reflected light.

[0065] A bracket 321 is provided at a predetermined position near the guide hole 110. The bracket 321 may be a component that extends laterally from the predetermined position near the guide hole 110 and extends to a position overlapping with the guide hole 110. Furthermore, an optical sensor 320 is fixedly mounted on the bracket 321 in such a way that it protrudes from the guide hole 110.

[0066] Here, the reflective area 311 can be a gradient label. Alternatively, the position detection member 310 can be a reflective label with a gradient formed on its outer surface.

[0067] Thus, during the introduction or withdrawal of the circuit breaker body 200 into or from the insertion space, the position of the circuit breaker body 200 moves linearly within the support 100.

[0068] At this time, the optical sensor 320 fixed at any position has a light-emitting part and a light-receiving part.

[0069] The light-emitting unit irradiates light onto the reflective region 311, which is a moving gradient region. Furthermore, the light reflected from the reflective region 311 is received by the light-receiving unit, thereby measuring the amount of reflected light.

[0070] For example, the reflective region 311 has a predetermined length and is formed as a gradient region, so the amount of light reflected at each position of the reflective region is different.

[0071] Therefore, it is possible to gradually increase or decrease the amount of light reflected from one end of the reflection region 311 to the other end.

[0072] As a result, the position detection component 310 moves simultaneously with the guide plate 210 on which the movable circuit breaker body 200 is mounted, so the amount of reflected light at a predetermined position in the reflection area 311 can be measured, and the moving position of the circuit breaker body 200 can be easily detected based on the measured amount of reflected light.

[0073] In addition, the present invention can linearly detect the position information of three positions of the circuit breaker body 200 (e.g., lead-out position, test position, and lead-in position), as well as the movement position within a predetermined movement range, thereby enabling accurate detection of the movement position of the circuit breaker body 200.

[0074] On the other hand, refer to Figure 6The position detection component 310 of the present invention is attached to a predetermined area exposed by the guide hole 110 on the side of the guide plate 210, and has a reflective area 312 that reflects different amounts of light along the length direction.

[0075] The position detection component 310 is attached to a setting area formed on the side of the guide plate 210.

[0076] The optical sensor 320 is disposed on the bracket 100 in a manner that is near the guide hole 110, and measures the movement position of the guide plate 210 on which the circuit breaker body 200 is mounted by emitting light into the reflection area 312 of the position detection member 310 and measuring the amount of reflected light.

[0077] Here, the reflective region 312 may be an inclined member that forms an inclined surface 312a from one end to the other.

[0078] Thus, during the introduction or withdrawal of the circuit breaker body 200 into or from the insertion space in the placement state of the guide plate 210, the position of the guide plate 210 moves linearly within the bracket 100.

[0079] At this time, the optical sensor 320 fixed at any position has a light-emitting part and a light-receiving part.

[0080] The light-emitting unit irradiates light onto the inclined surface 312a that has been moved. Furthermore, the light reflected from the inclined surface 312a is received by the light-receiving unit, thereby measuring the amount of reflected light.

[0081] For example, the inclined member has a predetermined length and is formed as an inclined surface 312a, so the amount of light reflected at each position of the reflective region 312 is different.

[0082] Therefore, it is possible to gradually increase or decrease the amount of light reflected from one end of the inclined surface 312a to the other end.

[0083] The position detection component 310 moves simultaneously with the moving guide plate 210, so the amount of reflected light at a predetermined position of the reflection area 312 can be measured, and the moving position of the circuit breaker can be easily detected based on the measured amount of reflected light.

[0084] In addition, the present invention can not only linearly detect the position information of the three positions of the circuit breaker body 200, but also linearly detect the movement position within a predetermined movement range, thereby enabling accurate detection of the movement position of the circuit breaker body 200.

[0085] Of course, when using inclined components, the distance to the inclined surface 312a can also be measured, and the moving position of the circuit breaker can be detected based on the measured distance value.

[0086] Figure 7 This is a perspective view showing another embodiment of the position detection unit of the present invention. Figure 8 This is a diagram showing a first example of a position detection member in another example of the position detection unit of the present invention. Figure 9 This is a diagram illustrating a second example of the position detection component of the present invention. Figure 10 It is along Figure 9 A sectional view cut along line AA.

[0087] Reference Figure 7 and Figure 8 A curvature hole 120 with a set curvature is formed on the side of the bracket 100 of the present invention.

[0088] A connecting pin 130 protrudes from the curvature hole 120 and connects to a connecting rod (not shown) disposed inside the bracket 100 and connected to the circuit breaker body 200. The connecting pin 130 is configured to move along the curvature hole 120. Thus, the movement of the connecting pin 130 is linked to the movement of the circuit breaker body 200.

[0089] The connecting pin 130 is linked to the circuit breaker body 200 by being introduced into or led out of the configuration space and moves along the curvature hole 120.

[0090] The position detection unit 400 includes: a position detection member 410 having a predetermined curvature along the length direction of the curvature hole 120 and disposed in the peripheral area of ​​the curvature hole 120, forming a reflection area 411 that reflects different amounts of light; and an optical sensor 420 disposed on the connecting pin 130, which measures the movement position of the circuit breaker body 200 by emitting light into the reflection area 411 of the position detection member 410 and measuring the amount of reflected light.

[0091] The position detection component 410 is disposed on the outer surface of the bracket 100 along the curvature of the curvature hole 120 in the peripheral area of ​​the curvature hole 120.

[0092] The optical sensor 420 is disposed on the connecting pin 130. The optical sensor 420 has a light-emitting part and a light-receiving part. The optical sensor 420 is fixed in the connecting pin 130 at a position that can emit light to and receive light in the reflective area 411.

[0093] A bracket 421 extending laterally is provided at the upper end of the connecting pin 130. The bracket 421 can be exposed through the curvature hole 120. An optical sensor 420 is fixedly mounted on the bracket 421. The optical sensor 420 can be exposed through the curvature hole 120.

[0094] The optical sensor 420 measures the movement position of the circuit breaker body 200 by emitting light into the reflection area 411 of the position detection member 410 and measuring the amount of reflected light.

[0095] Here, the reflective area 411 can be a gradient label. Alternatively, the position detection member 410 can be a reflective label with a gradient formed on its outer surface. The label is a curvature label.

[0096] Thus, during the introduction or withdrawal of the circuit breaker body 200 into or from the insertion space, the position of the circuit breaker body 200 moves linearly within the support 100.

[0097] At this time, the connecting pin 130 moves along the curvature hole 120. Here, the optical sensor 420 provided on the connecting pin 130 has a light-emitting part and a light-receiving part.

[0098] The light-emitting unit irradiates light onto the reflective region 411, which is a moving gradient region. Furthermore, the light reflected from the reflective region 411 is received by the light-receiving unit, thereby measuring the amount of reflected light.

[0099] For example, the reflective region 411 has a predetermined length and is formed as a gradient region, so that the amount of light reflected at each position of the reflective region 411 is different.

[0100] Therefore, it is possible to gradually increase or decrease the amount of light reflected from one end of the reflection region 411 to the other end.

[0101] Therefore, since the optical sensor 420 is attached to the moving connecting pin 130, the amount of reflected light at a predetermined position of the reflecting area 411 can be measured during the movement, and the moving position of the circuit breaker body 200 can be easily detected based on the measured amount of reflected light.

[0102] In addition, the present invention can not only linearly detect the position information of the three positions of the circuit breaker body 200, but also linearly detect the movement position within a predetermined movement range, thereby enabling accurate detection of the movement position of the circuit breaker.

[0103] On the other hand, refer to Figure 9 and Figure 10 The position detection component 410 of the present invention is disposed in the peripheral region of the curvature hole 120. The position detection component 410 forms a curvature that is the same as the curvature of the curvature hole 120.

[0104] The optical sensor 420 is disposed on the connecting pin 130 and measures the movement position of the circuit breaker body 200 by emitting light to the position detection component 410 and measuring the amount of reflected light.

[0105] Here, the reflective region 412 may be an inclined member having an inclined surface 412a formed from one end to the other.

[0106] Thus, during the introduction or withdrawal of the circuit breaker body 200 into or from the insertion space, the position of the circuit breaker body 200 moves linearly within the support 100.

[0107] At this time, the optical sensor 420 fixed at any position has a light-emitting part and a light-receiving part.

[0108] The light-emitting unit irradiates light onto the inclined surface 412a that has been moved. Furthermore, the light reflected from the inclined surface 412a is received by the light-receiving unit, thereby measuring the amount of reflected light.

[0109] For example, the inclined member has a predetermined length and is formed as an inclined surface 412a, so the amount of light reflected at each position of the reflective region 412 is different.

[0110] Therefore, it is possible to gradually increase or decrease the amount of light reflected from one end of the inclined surface 412a to the other end.

[0111] Therefore, since the position detection component 410 moves simultaneously with the moving circuit breaker body 200, the amount of reflected light at a predetermined position in the reflection area 412 can be measured, and the moving position of the circuit breaker can be easily detected based on the measured amount of reflected light.

[0112] In addition, the present invention can not only linearly detect the position information of the three positions of the circuit breaker body 200, but also linearly detect the movement position within a predetermined movement range, thereby enabling accurate detection of the movement position of the circuit breaker.

[0113] Of course, when using inclined components, the distance to the inclined surface 412a can also be measured, and the moving position of the circuit breaker can be detected based on the measured distance value.

[0114] Figure 11 This invention describes the introduction and extraction of a monitoring system.

[0115] Reference Figure 11 The inlet / outlet monitoring system of the present invention includes the aforementioned inlet / outlet position detection device.

[0116] The inlet and outlet monitoring system includes: a storage unit 500, which receives and stores the movement position of the circuit breaker body 200 linearly detected by the position detection units 300 and 400; a display unit 600, which displays the stored movement position of the circuit breaker body 200 to the outside; and a control unit 700, which controls three preset positions to overlap with the stored movement position of the circuit breaker body 200 and displays them through the display unit 600.

[0117] As described above, during the process of the circuit breaker body 200 being introduced into or drawn out of the insertion space of the bracket 100, the position detection units 300 and 400 of the present invention send information related to the movement position of the circuit breaker body 200 to the storage unit 500.

[0118] The storage unit 500 stores the moving position information of the moving circuit breaker body 200 in real time, and displays the moved position or the moving position information visually through the display unit 600.

[0119] This allows the operator to visually confirm the position of the circuit breaker body 200 within the bracket 100.

[0120] In addition, the control unit 700 of the present invention overlaps the three preset positions with the stored movement positions of the circuit breaker body 200 and displays them through the display unit 600, thereby enabling real-time confirmation of whether the circuit breaker body is accurately located in the three preset positions.

[0121] In the event that the actual moving position of the circuit breaker body 200 is inconsistent with the three preset positions, a device such as a handle can be used to forcibly correct the position of the circuit breaker body 200, or an additional moving device can be used to forcibly move the circuit breaker body 200 to correct its position.

[0122] Therefore, the present invention can linearly detect the position of the circuit breaker body 200 moving inside the bracket 100, and can confirm whether it is consistent with the preset operating position and correct the error.

[0123] While specific embodiments of the present invention have been described above, it is obvious that various modifications and implementations can be made without departing from the scope of the present invention.

[0124] Therefore, the scope of the present invention should not be limited to the illustrated embodiments, but should be defined by the appended claims and their equivalents.

[0125] That is, it should be understood that the above embodiments are exemplary in all respects and not restrictive, the scope of the invention is indicated by the appended claims rather than the detailed description, and all changes or modifications derived from the meaning, scope and equivalent concepts of the claims should be interpreted as being included within the scope of the invention.
