Description

Technical Field

[0001] This invention relates to a monitoring system for power equipment, and more specifically, to a monitoring system for power equipment capable of continuously sensing and detecting the precise position of a circuit breaker body moving within a support. Background Technology

[0002] Generally speaking, electrical equipment refers to all equipment capable of receiving, transmitting, and converting electrical energy.

[0003] Figure 1 This is a three-dimensional diagram showing this existing electrical equipment.

[0004] Reference Figure 1 The existing power equipment includes: a bracket 100, which has bracket terminals 110 for connecting to external power sources or load-side power lines and is fixed to a distribution panel; a circuit breaker body 200, which is mechanically and electrically connected or disconnected from the terminal portion of the bracket 100; and a beam portion 300 and a transfer portion 400, which serve as transfer devices for moving the circuit breaker body 200 to the connected or disconnected position.

[0005] Here, the connection position refers to the position where the circuit breaker body 200 is maximally close to the side of the bracket terminal 110 and electrically connected to it.

[0006] In addition, the separation position refers to the position where the circuit breaker body 200 is electrically separated from the support terminal 110 side to the greatest extent.

[0007] On the other hand, the test position refers to the position of the process of changing from the connection position to the separation position or from the separation position to the connection position.

[0008] in addition, Figure 2 and Figure 3 They are respectively shown according to Figure 1 A perspective view of the beam portion 300 and the transfer portion 400 at the separation and connection positions described in the figure.

[0009] in addition, Figure 4 These are cross-sectional views showing the beam portion 300 and the transfer portion 400 in existing power equipment according to their separation position, test position, and connection position.

[0010] Reference Figures 2 to 4 In existing electrical equipment, the beam 300 includes: a pair of handles 310 formed on the front of the beam 300; support ribs 320 formed on both sides of the beam 300; a spindle 330, one end of which is rotatably coupled to the center of the front of the beam 300; and a switch operating lever 340 formed on one side of the spindle 330.

[0011] In addition, the transfer part 400 includes a plurality of wheels 410 formed at both sides thereof and a plurality of micro switches 420 operated by the switch operating lever 340, as the spindle 330 rotates, the interval between the transfer part 400 and the bracket terminal 110 is adjusted. Figure 2 and Figure 3 As shown, the interval between the transfer part 400 and the beam part 300 is adjusted.

[0012] That is, as the spindle 330 rotates clockwise or counterclockwise, the interval between the transfer part 400 and the bracket terminal 110 is adjusted.

[0013] In addition, the switch operating lever 340 includes a groove part 341 formed to correspond to the movement range of the transfer part 400, a rear end inclined part 342 formed at one end side of the groove part 341, and an upper flat part 343 formed on the top surface except for the groove part 341 and the rear end inclined part 342.

[0014] In addition, the micro switch 420 includes first to third micro switches 421, 422, 423.

[0015] In more detail, the first micro switch 421 includes a first contact lever 421a formed to contact the switch operating lever 340 at the lower side thereof, and is formed closest to the beam part 300 side.

[0016] In addition, the second micro switch 422 includes a second contact lever 422a formed to contact the switch operating lever 340 at the lower side thereof, and is formed adjacent to the rear end side of the first micro switch 421.

[0017] In addition, the third micro switch 423 includes a third contact lever 423a formed to contact the switch operating lever 340 at the lower side thereof, and is formed at the rear end side of the transfer part 400.

[0018] In this existing power device, a method of detecting the relative position between the terminal 110 side of the bracket 100 and the circuit breaker body 200 using the transfer part 400 is as follows.

[0019] Referring to Figure 4 (a), at the separation position of the existing power device, the interval between the transfer part 400 and the beam part 300 becomes the smallest.

[0020] As a result, the distance between the circuit breaker body 200 and the bracket terminal 110 becomes the largest.

[0021] In addition, the first contact rod 421a is in contact with the upper flat portion 343, and the second contact rod 422a and the third contact rod 423a are in contact with the groove portion 341, respectively.

[0022] On the other hand, referring to Figure 4 (b) of FIG. 4, in the test position of the existing power device, as the distance between the beam portion 300 and the transfer portion 400 increases, the first contact rod 421a and the second contact rod 422a are in contact with the groove portion 341, respectively.

[0023] In addition, the third contact rod 423a is in contact with the upper flat portion 343 through the rear end inclined portion 342.

[0024] In addition, referring to Figure 4 (c) of FIG. 4, in the connection position of the existing power device, the interval between the transfer portion 400 and the beam portion 300 becomes the maximum.

[0025] Accordingly, the circuit breaker body 200 is in contact with and electrically connected to the bracket terminal 110.

[0026] At this time, the first contact rod 421a is in contact with the groove portion 341, and the second contact rod 422a is in contact with the upper flat portion 343 through the rear end inclined portion 342.

[0027] As described above, in the related art, the interval between the beam portion 300 and the transfer portion 400 is adjusted in a state in which the switch operating lever 340 is combined with the beam portion 300, and thus the position of the circuit breaker body 200 is detected based on whether the plurality of micro switches 420 fixedly provided in the transfer portion 400 are in contact.

[0028] Accordingly, in the related art, although the position can be detected with respect to the separation position, the test position, and the connection position, respectively, the changing distance between the circuit breaker body 200 and the bracket terminal 110 cannot be detected. SUMMARY

[0029] PROBLEMS TO BE SOLVED BY THE INVENTION

[0030] An object of the present application is to provide a monitoring system of a power device capable of linearly sensing and detecting the position of a circuit breaker body in an entire operation range with a relatively simple structure.

[0058] The above objects, features and advantages will be described in detail below with reference to the accompanying drawings, so that those of ordinary skill in the art to which the present application pertains can easily implement the technical idea of the present application. In explaining the present application, if it is judged that a detailed explanation of the known technology related to the present application can unnecessarily obscure the gist of the present application, the detailed explanation thereof will be omitted. Hereinafter, the preferred embodiments of the present application will be described in detail with reference to the accompanying drawings. Like reference numerals are used throughout the drawings to designate like elements.

[0059] Hereinafter, in the case where an arbitrary constituent is configured "on (or under) the upper (or lower) portion of a constituent element" or "on (or under) the constituent element", it means that the arbitrary constituent can be disposed in contact with the top surface (or the bottom surface) of the constituent element, and other constituents can be further disposed between the constituent element and the arbitrary constituent disposed on (or under) the constituent element.

[0060] Furthermore, when a constituent element is described as being "connected", "combined", or "linked" with another constituent element, it should be understood that the constituent elements can be directly connected or linked to each other, but other constituent elements can also be "interspersed" between the constituent elements, or the constituent elements can be "connected", "combined", or "linked" through other constituent elements.

[0061] Unless the context clearly specifies otherwise, the singular expressions used in this specification include the plural expressions.

[0062] In this invention, terms such as "consisting of" or "comprising" should not be interpreted as necessarily including all the various constituent elements or steps described in the specification, but should be interpreted as possibly excluding some of the constituent elements or steps, or possibly including additional constituent elements or steps.

[0063] Throughout the specification, when “A and / or B” is mentioned, it means A, B or A and B unless otherwise specified to the contrary. When “C to D” is mentioned, it means C and below unless otherwise specified to the contrary.

[0064] The following will describe a power equipment monitoring system according to several embodiments of the present invention.

[0065] In the power equipment monitoring system of the present invention, the same reference numerals are given to the same configuration as those of existing power equipment.

[0066] Figure 5 This is a perspective view showing the configuration of a power equipment monitoring system according to an embodiment of the present invention.

[0067] in addition, Figure 6 This is a perspective view showing the circuit breaker body of a power equipment monitoring system detached from the bracket according to an embodiment of the present invention.

[0068] Reference Figure 5 and Figure 6 The power equipment monitoring system of the present invention includes: a bracket 100 having a bracket terminal 110; a beam 300 fixedly disposed on the bracket 100; a transfer part 400 movably formed to adjust its spacing from the beam 300; and a circuit breaker body 200 mounted on the transfer part 400 to connect or separate from the bracket terminal 110.

[0069] Furthermore, in the power equipment monitoring system of the present invention, the circuit breaker includes the circuit breaker body 200, the beam portion 300, and the transfer portion 400.

[0070] In addition, the monitoring system for a power device according to the present application includes: at least one or more position sensing area portions 500, 500' formed in the circuit breaker body 200 or the beam portion 300 in correspondence with a moving range of the transfer portion 400; at least one or more sensor modules 600, 600' fixedly installed in the transfer portion 400 or the bracket 100 to sense a moving characteristic of the position sensing area portion 500, 500' in real time; a control portion 800 receiving the moving characteristic of the position sensing area portion 500, 500' sensed by the sensor module 600, 600' and detecting a moving characteristic of the circuit breaker body 200 based on the same; and a display portion 900 outputting the moving characteristic of the circuit breaker body 200 detected by the control portion 800.

[0071] At this time, the connection between the sensor module 600, 600' and the control portion 800 and the connection between the control portion 800 and the display portion 900 can apply various wired / wireless communication networks.

[0072] In addition, the display portion 900 can also be formed as a portable terminal of an administrator.

[0073] On the other hand, in the monitoring system for a power device according to the present application, the separation position refers to a position where the circuit breaker body 200 is maximally spaced apart from the bracket terminal 110 side to be electrically separated.

[0074] That is, the separation position is a state where the interval between the beam portion 300 and the transfer portion 400 is minimized.

[0075] In addition, in the monitoring system for a power device according to the present application, the connection position refers to a position where the circuit breaker body 200 is maximally close to the bracket terminal 110 side to be electrically connected thereto.

[0076] That is, the connection position, which is a state where the interval between the beam portion 300 and the transfer portion 400 is maximized, is a state where a terminal formed in the circuit breaker body 200 is combined with the bracket terminal 110.

[0077] In addition, in the monitoring system for a power device according to the present application, the operation position refers to a state where the interval between the beam portion 300 and the transfer portion 400 is adjusted in a process of changing from the connection position to the separation position or changing from the separation position to the connection position.

[0078] The beam portion 300 includes: a pair of handle bars 310 formed at a front surface of the beam portion 300; a support rib 320 formed at both sides of the beam portion 300; and a mandrel 330 having one end combined with a central portion of the front surface of the beam portion 300 in a rotatable manner.

[0079] More specifically, the handle bar 310, which serves as a portion for an operator to hold when the bracket 100 mounts or separates the beam part 300 and the transfer part 400, can be formed in various shapes.

[0080] In addition, the beam part 300 is fixed to the bracket 100 by being inserted and fixed to both sides of the bracket 100 through the support ribs 320.

[0081] In addition, the spindle 330 is coupled to the transfer part 400 in a manner that one end thereof is coupled to the central part of the beam part 300 and the other end thereof faces the bracket terminal 110 side.

[0082] Thus, it can be formed such that the interval between the beam part 300 and the transfer part 400 is adjusted in the case where the spindle 330 rotates in a clockwise direction or a counterclockwise direction.

[0083] In addition, the rotation of the spindle 330 can be manually operated by an operator by fastening a connection mechanism to a connection port formed in the front surface of the beam part, or can be automatically performed using a driving motor or the like.

[0084] On the other hand, the movement characteristic of the circuit breaker body 200 output from the display part 900 is preferably at least any one or more of the movement distance of the circuit breaker body 200, the remaining distance from the connection or separation position, the movement speed, the variation amount of the movement speed, the amount of engagement between the circuit breaker body 200 and the bracket terminal 110.

[0085] More preferably, the movement characteristic of the circuit breaker body 200 output from the display part 900 can be output in a graph or a chart including numerical values or the like so that the administrator can easily confirm.

[0086] In addition, in the case where the circuit breaker body 200 is in the connection position, if the amount of engagement between the circuit breaker body 200 and the bracket terminal 110 exceeds the allowable range of the preset amount of engagement, the control part 800 can generate a notification alarm and output it to the display part 900.

[0087] On the other hand, since the sizes of the circuit breaker body 200 and the bracket 100 can vary according to their uses, the amount of engagement between the circuit breaker body 200 and the bracket terminal 110 is preferably configured to be automatically extracted by the control part 800 according to the distance between the circuit breaker body 200 and the bracket 100 when the sizes of the circuit breaker body 200 and the bracket 100 and the specifications of the bracket terminal 110 are input.

[0088] Thus, the monitoring system of the power device of the present application can minimize heat generation, device damage, safety accidents, and the like due to incorrect coupling between the circuit breaker body 200 and the bracket terminal 110.

[0089] In addition, in a case where the same type of characteristics in the movement characteristics of the position sensing area part 500 sensed by the sensor module 600 are sensed in two or more, the control part 800 can also generate a notification alarm and output to the display part 900 if the error between the sensed characteristics exceeds the error allowance.

[0090] More specifically, the control part 800 compares the movement characteristics sensed by the plurality of sensor modules 600 formed to be opposite to the plurality of position sensing area parts 500, respectively, and if these movement characteristics are different, can guide the administrator to perform inspection on the position detection device including the position sensing area part 500 and the sensor module 600 and the entire device through the notification alarm output to the display part 900.

[0091] Thus, the monitoring system of the power device of the present application can grasp the error of the position detection device and the movement characteristic output error of the circuit breaker body 200 generated by the malfunctions of the sensor module 600 or the malfunctions of the transfer part 400 in a short time.

[0092] On the other hand, Figure 7 and Figure 8 are perspective views each showing a beam part and a transfer part according to a separation position and a connection position in the monitoring system of the power device according to an embodiment of the present application.

[0093] In addition, Figure 9 are perspective views each showing a positioning rod in the monitoring system of the power device according to an embodiment of the present application, Figure 10 are perspective views each showing a top surface and a bottom surface of a sensor module in the monitoring system of the power device according to an embodiment of the present application.

[0094] Referring to Figures 7 to 10 In the monitoring system of the power device according to the present application, the position sensing area part 500 can be formed in a positioning rod 350, one end of which is coupled with the beam part 300 and the other end is formed as a free end of the bracket terminal 110 side, and the sensor module 600 can be fixedly coupled to one side of the transfer part 400 and sense the movement characteristics of the position sensing area part 500.

[0095] More specifically, one end of the positioning rod 350 is coupled with the beam part 300 in a manner parallel to the spindle 330, and the other end is formed as a free end.

[0096] In addition, the sensor module 600 can include at least one or more of a non-contact sensor 610 formed opposite to the position sensing area part 500 and a contact sensor 620 formed in contact with the position sensing area part 500.

[0097] At this time, the non-contact sensor 610 can be formed as an optical sensor capable of sensing a shadow, a distance, a shape, etc. of a predetermined area in the position sensing area part 500.

[0098] In addition, as shown in (b) of FIG. 6, the contact sensor 620 can be formed to extend to the side of the positioning rod 350 and to be in contact with the positioning rod 350 by an FPCB (Flexible Printed Circuit Board) or an elastic member, etc. Figure 10

[0099] On the other hand, as described above, the position sensing area part 500 can be formed along the moving range of the transfer part 400, and more preferably, as shown in (a) of FIG. 7, can be formed as a positioning label 510 in which a shadow changes according to a position, for example, a gradient band. Figure 9

[0100] At this time, as shown in (b) of FIG. 7, the positioning label 510 can also be formed as a polygon, for example, a triangle, etc. in which an area changes in the moving direction of the circuit breaker body 200. Figure 9

[0101] On the other hand, as shown in (c) of FIG. 7, the position sensing area part 500 can also include a positioning inclined part 520 in which one end is formed to be protruded or recessed with respect to the top surface of the positioning rod 350. Figure 9 At this time, as described above, a gradient band in which a shadow changes can also be attached to the top surface of the positioning inclined part 520.

[0102] In addition, as shown in (d) of FIG. 7, the position sensing area part 500 can also include a plurality of positioning protrusions 530 formed at a predetermined interval.

[0103] Figure 9 More preferably, the positioning protrusions 530 can be formed in a number, a formation position, a shape, etc. that gradually change in the moving direction of the transfer part 400, so that the position of the circuit breaker body 200 can be detected by the sensor module 600.

[0104] In addition, the position sensing area part 500 can also mix the positioning protrusions 530 and the positioning label 510.

[0105] In addition, the position sensing area part 500 can also mix the positioning protrusions 530 and the positioning label 510.

[0106] ​​​​On the other hand, in the monitoring system for the power device according to the present application, the transfer unit 400 can include a plurality of position rod guides 430 formed adjacent to or in contact with both side surfaces of the position rod 350.

[0107] In addition, as shown in Figure 6 , the position rod guide 430 is preferably formed with a brush cleaner 700 capable of removing dust or foreign matter, etc. stacked on the position sensing area 500.

[0108] Accordingly, the monitoring system for the power device according to the present application can minimize sensing errors of the sensor module 600 caused by foreign matter stacked on the position sensing area 500.

[0109] In addition, the contact sensor 620 can also sense the position of the circuit breaker body 200 by contacting the position tilt 520 and sensing the change in height of the position tilt 520.

[0110] On the other hand, Figure 11 and Figure 12 are side sectional views of the monitoring system for the power device according to an embodiment of the present application according to the separation position and the connection position, respectively.

[0111] In addition, Figure 13 are side views showing the position sensing area in the monitoring system for the power device according to an embodiment of the present application, respectively.

[0112] Referring to Figures 11 to 13 , in the monitoring system for the power device according to the present application, the position sensing area 500' can be formed on the side surface of the circuit breaker body 200, and the sensor module 600' can be fixedly coupled to the inner side surface of the bracket 100 and sense the movement characteristics of the position sensing area 500'.

[0113] At this time, as shown in (a) of Figure 13 , the position sensing area 500' can be formed as a position tag 510' in which the shade changes according to the position, such as a gradient band.

[0114] In addition, as shown in (b) of Figure 13 , the position tag 510' can also be formed as a polygon, such as a triangle, etc., in which the area changes in the movement direction of the circuit breaker body 200.

[0115] On the other hand, as shown in (c) of Figure 13 , the position sensing area 500' can also include a position tilt 520' in which one end is formed to be protruded or recessed with respect to the side surface of the circuit breaker body 200.

[0116] At this time, as described above, a gradient band of shadow change can also be attached to the top surface of the positioning inclined portion 520`.

[0117] In addition, as Figure 13 As shown in (d), the position sensing area portion 500` can also include a plurality of positioning protrusions 530` formed at predetermined intervals.

[0118] More preferably, the positioning protrusions 530` can be formed in a number, a formation position, a shape, etc. gradually changing in the moving direction of the transfer portion 400, so that the position of the circuit breaker body 200 can be detected by the sensor module 600.

[0119] In addition, the position sensing area portion 500` can also mix the positioning protrusions 530` and the position band 510`.

[0120] On the other hand, in the monitoring system for the power device of the present application, the position sensing area portion 500` can be formed on the inner side surface of the bracket 100, and the sensor module 600` can be formed on the side surface of the circuit breaker body 200.

[0121] However, as described above, the sensor module 600` is more preferably formed on the bracket 100 to achieve the connection wiring and control, inspection, etc. of the sensor module 600`.

[0122] At this time, in the case where the sensor provided on the sensor module 600` is an optical sensor including a wireless communication device, according to the design specification, the position sensing area portion 500` can be formed on the inner side surface of the bracket 100, and the sensor module 600` can be formed on the side surface of the circuit breaker body 200.

[0123] More specifically, in the case where the bracket terminals 110 to which the circuit breaker body 200 is electrically and mechanically connected are formed in three phases R, S, T, if the connection between these terminals 110 is not performed at the same time, damage to the power device and a power accident can occur.

[0124] Therefore, in the monitoring system for the power device of the present application, the position sensing area portion 500` is formed on both side surfaces of the circuit breaker body 200, and thus the sensor module 600` is preferably formed on the inner surfaces of both sides of the bracket 100, so that in the case where the bracket terminals 110 are three phases, the connection or separation between the respective terminals can be performed at the same time.

[0125] In addition, in the case where the positions of the circuit breaker body 200 sensed by the two sensor modules 600` are not consistent, a notification alarm can be generated on the display portion 900.

[0126] Thus, in the monitoring system of the power device of the present application, the circuit breaker body 200 is connected or disconnected from the bracket terminal 110 in a predetermined manner, thereby being able to prevent damage to the device and power accidents.

[0127] On the other hand, as shown in the drawings, the sensor module 600` can include at least one or more of a non-contact sensor 610` formed to be opposite to the position sensing area part 500` and a contact sensor 620` formed in a roller type to be in contact with the position sensing area part 500`. Figure 6

[0128] In addition, a cleaner 700` of a brush or roller type can be included at the front or rear side of the sensor module 600`, to remove dust or foreign matter attached to the surface of the position sensing area part 500`.

[0129] On the other hand, the cleaner 700` is more preferably provided at the front of the sensor module 600`.

[0130] In the case where the cleaner 700` is adjacent to the bracket terminal 110 side, the cleaner 700` can be damaged or an electrical problem can occur due to an arc or the like, and thus the cleaner 700 is preferably formed to be spaced apart from the bracket terminal 110 as much as possible.

[0131] As described above, the present application has been described with reference to the drawings illustrating examples, but the present application is not limited to the examples and drawings disclosed in the present specification, and it is obvious that a person of ordinary skill in the art can make various modifications within the scope of the technical idea of the present application. Furthermore, even if the effects according to the configuration of the present application are not explicitly described and explained when the embodiments of the present application are described above, it is naturally recognized that the effects predicted by the configuration can be obtained.​
