Abstract
Description
Technical Field
[0001] This utility model relates to the field of power equipment technology, specifically to an indicator device that facilitates the monitoring of the opening and closing position of a GIS disconnector. Background Technology
[0002] Gas-insulated switchgear (GIS) is widely used due to its advantages such as small footprint, safe and reliable operation, good electrical performance, and convenient maintenance. Because the contacts of a GIS disconnector are enclosed within the tank, operators cannot directly observe the contact between the moving and stationary contacts when monitoring via camera, nor can they directly observe the contact action and positioning of the contacts during operation. In switching operations, inaccurate judgment of the disconnector's position frequently leads to equipment damage and short-circuit tripping. Therefore, accurately determining the actual position and positioning of the GIS disconnector is extremely important for its monitoring and safe operation.
[0003] Therefore, clear indicating devices are needed for better monitoring of GIS disconnectors. Currently, operators typically determine the disconnector's position by observing the mechanism box indicator or the external linkage output indicator. The mechanism box indicator is implemented via an auxiliary linkage connected to the motor drive output linkage. The external linkage output indicator is generally installed on the input shaft of the disconnector tank. Its disconnector position markings are usually pre-painted with paint before leaving the factory or drawn on-site with an oil-based pen before the equipment is put into operation. During operation, the position of the disconnector is determined by comparing the external linkage output indicator with the marked position markings. The defects of this type of indicator are quite obvious. For example, the indicator plate is inside the mechanism box. When the connection between the auxiliary linkage and the motor drive output linkage is unreliable, the indicator plate cannot accurately reflect the actual position of the disconnector. Some manufacturers' equipment only has a disconnector mechanism box position indicator plate, without an external linkage output indicator, or although it is equipped with an external linkage output indicator, the indication is inaccurate. The mechanism box indicator plate does not have a disconnection / closed position marking line, and there is a visual error in observing the indicator plate, making it impossible to accurately judge whether the disconnector is disconnected or closed. During the operation of the disconnector, after multiple operations, various parts of the transmission linkage may become loose or jammed. Since the existing mechanism box indicator plate and external disconnector position indicator are not installed on the input shaft of the GIS tank, they cannot accurately reflect the actual position of the disconnector. During long-term operation under heat and rain, the paint or oil-based marking line of the disconnector position is prone to blurring and peeling, affecting the accuracy of disconnector position judgment.
[0004] Chinese patent CN209641537U discloses a GIS disconnector position indicator, which effectively addresses some shortcomings of existing indicators. However, it still has some deficiencies, such as the lack of a zeroing function. When the position of the disconnector position slider is changed, the deflection angle of the pointer cannot be directly read. Furthermore, the disconnector position slider is easily affected by equipment vibration and external impact, which can mislead staff and cause inconvenience to the monitoring of the GIS disconnector position. Utility Model Content
[0005] The purpose of this utility model is to provide an indicator device that has a zeroing function and can read the opening and closing status of the disconnector without calculation, which is convenient for GIS disconnector position monitoring.
[0006] This utility model is achieved through the following technical solution: an indicator device for facilitating the monitoring of the opening and closing position of a GIS disconnector, comprising:
[0007] Mounting plate, on which a rotating shaft is rotatably mounted, the rotating shaft being connected to the knife switch transmission linkage;
[0008] A transparent cover is mounted on a mounting plate and rotatably connected to a rotating shaft. The transparent cover has a circular groove with an opening facing the mounting plate, and a scale is arranged in a circular array around the axis of the rotating shaft on the side of the transparent cover away from the mounting plate.
[0009] The circuit breaker positioning block is slidably mounted on the mounting plate and connected to the arc surface of the transparent cover. The circuit breaker positioning block is provided with a locking component that restricts the rotation of the transparent cover and the mounting plate.
[0010] A closing positioning block is slidably mounted on a mounting plate and rotates around the center of a transparent cover. A locking mechanism is provided on the closing positioning block to restrict its relative movement with respect to the mounting plate.
[0011] And a pointer, which is set on the rotating shaft and located in a circular groove, and the pointer points to the scale.
[0012] The working principle of this technical solution is as follows: the mounting plate serves as the basic carrier, and the positioning block slides stably through the annular groove A; the transparent cover protects the scale (to prevent scratches) and limits the pointer position through the circular groove (to prevent scratches); the opening / closing positioning blocks mark the opening and closing reference positions respectively, and work with the pointer to achieve status visualization; the locking components (slider, spring, block, etc.) have a simple and reliable structure and are easy to operate (unlock by pulling the rod).
[0013] To better realize this utility model, the mounting plate is further described as a circular plate coaxial with the rotating shaft, and a first annular groove coaxial with it is provided on the arc surface of the mounting plate. Both the opening and closing positioning blocks are provided with protrusions, and the protrusions are inserted into the first annular groove and slidably connected to its inner wall.
[0014] To better realize this utility model, the locking assembly further includes a slider, a slide rod, and a spring. Several slots are arranged in a circular array around the axis of the arc-shaped inner wall of the first annular groove. A sliding groove is provided on the tripping positioning block, and the slider is slidably disposed within the sliding groove. A locking block is provided on the side of the slider facing the mounting plate, and the locking block is inserted into the corresponding slot and slidably connected to its inner wall. The slide rod is connected to the side of the slider away from the locking block, and a pull rod is provided at one end of the slide rod extending out of the tripping positioning block. The spring is sleeved on the slide rod, and both ends of the spring abut against the side of the slider away from the locking block and the inner wall of the sliding groove, respectively.
[0015] To better realize this utility model, the locking mechanism further includes a locking component and a positioning screw. The connection structure between the closing positioning block and the locking component is the same as the connection structure between the opening positioning block and the locking component. A second annular groove is arranged in a ring array around its axis on the end face of the mounting plate. The positioning screw is threadedly connected to the closing positioning block, and the threaded end of the positioning screw is inserted into the second annular groove and slidably connected to its inner wall.
[0016] To better realize this utility model, the closing positioning block is further provided with an arrow pointing to the scale.
[0017] To better realize this utility model, a light strip is further provided on the pointer on the side facing the scale.
[0018] To better realize this utility model, further, a plurality of countersunk holes are provided on the mounting plate.
[0019] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0020] (1) This utility model uses the tripping positioning block and the transparent cover to be linked. The position of the transparent cover can be adjusted by the locking components (spring, block, slot) so that the pointer points to the zero mark when the knife switch is tripped, thus solving the problem of zero adjustment.
[0021] (2) This utility model has a ring scale on the transparent cover, with the pointer inside the circular groove pointing to the scale. The closing positioning block marks the closing position with an arrow. The deflection angle can be read directly without calculation, which simplifies the operation.
[0022] (3) The opening positioning block of this utility model adopts a locking component of "spring + card block + card slot" and the closing positioning block adopts a double fixing of "locking component + positioning screw". It effectively resists vibration and external impact, avoids displacement of positioning block, and solves the problem of unstable positioning of existing devices. Its structural design is reasonable, its functions are targeted, and its details are well considered. It effectively solves the core defects of existing devices and has practicality and feasibility.

[0031] Example 1:
[0032] The main structure of this embodiment is as follows: Figures 1-3 As shown, it includes:
[0033] Mounting plate 1, on which a rotating shaft 3 is rotatably mounted, the rotating shaft 3 being connected to a knife switch transmission link 4;
[0034] A transparent cover 5 is mounted on a mounting plate 1 and rotatably connected to a rotating shaft 3. The transparent cover 5 has a circular groove 51 with an opening facing the mounting plate 1, and a scale 52 is arranged in a ring array around the axis of the rotating shaft 3 on the side of the transparent cover 5 away from the mounting plate 1.
[0035] The circuit breaker positioning block 6 is slidably mounted on the mounting plate 1 and connected to the arc surface of the transparent cover 5. The circuit breaker positioning block 6 is provided with a locking component 8 that restricts the rotation of the transparent cover 5 and the mounting plate 1.
[0036] The closing positioning block 7 is slidably mounted on the mounting plate 1 and rotates around the center of the transparent cover 5. The closing positioning block 7 is provided with a locking mechanism that restricts its relative movement with respect to the mounting plate 1.
[0037] And a pointer 10, which is mounted on the rotating shaft 3 and located in the circular groove 51, and the pointer 10 points to the scale 52.
[0038] Fix the mounting plate 1 onto the equipment, then connect the knife switch transmission linkage 4 and the rotating shaft 3 as shown in the diagram. With the knife switch in the open position, pull the lever 85 on the open positioning block 6. The lever 85 drives the slider 82 to slide, causing the locking block 83 to disengage from the slot 102. At this time, by moving the open positioning block 6, the transparent cover 5 rotates together until the arrow of the pointer 10 points to the zero mark of the scale 52. Then release the lever 85. Under the tension of the spring 86, the slider 82 automatically slides and pushes the locking block 83 back into the corresponding slot 102. The tripping positioning block 6 and the transparent cover 5 are fixed, and the zero mark of the scale 52 is the fully tripped position of the knife switch. Then, the knife switch is controlled to close, and the pointer 10 automatically swings and moves toward the second mark on the scale 52. This mark is the closed position. The closing positioning block 7 is adjusted in the above manner so that its arrow 71 and the pointer 10 point to the same mark. Since the pointer 10 is inside the transparent cover 5, the pointer will not rub against the scale 52. No matter how the equipment vibrates, or even if the positioning block on this device is subjected to external force impact, its predetermined position will not change.
[0039] The mechanical action of the knife switch is converted into the rotational motion of the pointer by the linkage between the rotating shaft and the knife switch transmission linkage, which directly reflects the status of the knife switch. The circular groove design of the transparent cover isolates the pointer from the outside, preventing the pointer from scratching the scale and protecting the scale. The opening positioning block is linked with the transparent cover and can calibrate the opening reference (zero scale), solving the problem of traditional devices not having a zeroing function. The closing positioning block can slide and mark the closing reference position, realizing a direct comparison of the opening and closing status.
[0040] After the mounting plate is fixed, the disconnector's transmission linkage drives the rotating shaft to rotate, and the pointer on the shaft rotates synchronously with the disconnector's movement. The scale on the transparent cover is distributed in a ring around the rotating shaft, and the pointer always points to the scale, displaying the disconnector's deflection angle in real time. When opening, the transparent cover is rotated by adjusting the opening positioning block, so that the pointer points to the zero mark on the scale (calibrating the opening reference), and then the transparent cover is fixed by the locking assembly. When closing, the pointer rotates with the disconnector to the new scale, the closing positioning block is adjusted to that scale (marking the closing reference), and then fixed by the locking mechanism. In subsequent operations, the pointer is compared with the scale marked on the opening / closing positioning block to quickly determine whether the disconnector is in position.
[0041] Example 2:
[0042] This embodiment further defines the mechanism of the mounting plate 1 based on the above embodiments, such as... Figures 1-3As shown, the mounting plate 1 is a circular plate coaxial with the rotating shaft 3. A first annular groove 101 coaxial with it is provided on the arc surface of the mounting plate 1. Both the opening positioning block 6 and the closing positioning block 7 are provided with protrusions, which are inserted into the first annular groove 101 and slidably connected to its inner wall. This configuration optimizes the sliding stability of the opening / closing positioning blocks; the annular groove A is coaxial with the rotating shaft, ensuring that the sliding trajectory of the positioning block is a standard arc, avoiding reference mark errors caused by sliding offset; the protrusions slide within the annular groove A, limiting the radial displacement of the positioning block, preventing the positioning block from detaching from the mounting plate, and improving sliding smoothness and structural stability.
[0043] Based on the above embodiment, the opening and closing positioning blocks are embedded in the annular groove A of the mounting plate via bottom protrusions. When adjusting the opening positioning block, the protrusion slides along the annular groove A, causing the transparent cover to rotate concentrically around the axis, ensuring the accuracy of zero-scale calibration. When adjusting the closing positioning block, the protrusion slides along the annular groove A, ensuring that the marked closing reference is concentric with the scale, avoiding reading deviations caused by positioning block offset. During the sliding process, the inner wall of the annular groove A forms a guiding constraint on the protrusion, preventing the positioning block from jamming or shaking. Other parts of this embodiment are the same as those in the above embodiment and will not be described again.
[0044] Example 3:
[0045] This embodiment further defines the structure of the locking component 8 based on the above embodiments, such as... Figures 1-3 As shown, the locking assembly 8 includes a slider 82, a slide rod 84, and a spring 86. Several slots 102 are arranged in a circular array around the axis of the arc-shaped inner wall of the first annular groove 101. A sliding groove 81 is provided on the tripping positioning block 6, and the slider 82 is slidably disposed within the sliding groove 81. A locking block 83 is provided on the side of the slider 82 facing the mounting plate 1, and the locking block 83 is inserted into the corresponding slot 102 and slidably connected to its inner wall. The slide rod 84 is connected to the side of the slider 82 away from the locking block 83, and a pull rod 85 is provided at one end of the slide rod 84 extending out of the tripping positioning block 6. The spring 86 is sleeved on the slide rod 84, and both ends of the spring 86 abut against the side of the slider 82 away from the locking block 83 and the inner wall of the sliding groove 81, respectively. This design optimizes the locking reliability of the tripping positioning block, solving the problem of traditional positioning blocks being easily displaced by vibration or external force; the spring-driven block-slot cooperation achieves "automatic locking," fixing the position of the transparent cover without additional tools; the slots are distributed in a ring array, allowing for multi-level fine-tuning to meet the calibration requirements of different knife switch tripping benchmarks; the pull rod design makes unlocking operation convenient, balancing fixed reliability and adjustment flexibility.
[0046] Locked state: The spring is in its natural extension state, pushing the slider to insert the locking block into the locking slot of the annular groove A. The tripping positioning block is fixed relative to the mounting plate, and the transparent cover cannot rotate (ensuring the stability of the tripping reference).
[0047] Adjustment status: Pull the lever, which drives the slider to compress the spring, the locking block disengages from the slot, and the opening positioning block can slide along the annular groove A, causing the transparent cover to rotate and calibrate the zero scale;
[0048] Re-locking: Loosen the pull rod, the spring returns to its original position, pushing the slider, and the locking block re-engages into the corresponding slot. The position of the tripping positioning block and the transparent cover is fixed, significantly improving vibration resistance. Other parts of this embodiment are the same as those in the above embodiment and will not be repeated.
[0049] Example 4:
[0050] This embodiment further defines the structure of the locking component 8 based on the above embodiments, such as... Figures 1-3 As shown, the locking mechanism includes a locking component 8 and a positioning screw 9. The connection structure between the closing positioning block 7 and the locking component 8 is the same as the connection structure between the opening positioning block 6 and the locking component 8. A second annular groove 103 is arranged in a circular array around the axis of the mounting plate 1 on its end face. The positioning screw 9 is threadedly connected to the closing positioning block 7, and the threaded end of the positioning screw 9 is inserted into the second annular groove 103 and slidably connected to its inner wall. This arrangement enhances the fixing reliability of the closing positioning block, preventing it from shifting due to equipment vibration or external impact. The dual fixing of the locking component (same as in embodiment 3) and the positioning screw forms a dual constraint of "mechanical clamping + threaded tightening," resulting in a fixing strength far exceeding that of a single locking method. The annular groove B provides a sliding trajectory for the positioning screw, ensuring that the positioning screw does not detach from the mounting plate during adjustment, balancing adjustment flexibility and fixing stability.
[0051] Based on the above embodiments, the fixing process of the closing positioning block is as follows: unlock the locking assembly (pull the lever to disengage the locking block from the slot), slide the closing positioning block to the closing reference scale; release the lever, and the locking block of the locking assembly engages with the slot, achieving initial fixing; tighten the positioning screw so that its threaded end presses into the inner wall of the annular groove B, further restricting the sliding of the closing positioning block through the thread preload, forming double fixing; in subsequent operations, even if affected by vibration, the double locking can ensure that the closing reference mark does not shift. The other parts of this embodiment are the same as those in the above embodiments and will not be described again.
[0052] Example 5:
[0053] This embodiment further defines the structure of the closing positioning block 7 based on the above embodiment, such as... Figures 1-3As shown, the closing positioning block 7 is provided with an arrow 71 pointing to the scale 52. This design enhances the visual recognizability of the closing reference; the arrow points directly to the scale, forming a direct comparison with the pointer's direction, allowing staff to quickly determine whether the pointer is aligned with the closing reference, reducing reading errors; the arrow protrudes from the surface of the closing positioning block, making it easier to observe in complex equipment environments.
[0054] After the closing positioning block is adjusted to the closing reference scale, the arrow should be aligned with that scale. When closing the disconnect switch, the pointer should point to the same scale as the arrow, indicating that the closing is complete. If the pointer does not reach the arrow position, it indicates that the disconnect switch is not closed enough. If it exceeds the arrow position, it indicates that the closing is over-closed. The deviation can be quickly judged by the visual guidance of the arrow. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.
[0055] Example 6:
[0056] This embodiment, based on the above embodiment, further adds a light strip 11, such as... Figure 1 As shown, a light strip 11 is centrally positioned on the side of the pointer 10 facing the scale 52. This arrangement solves the reading problem in low-light environments (such as at night or in dimly lit environments inside equipment rooms); the light strip is located on the side of the pointer pointing to the scale, and when it is lit, it directly illuminates the corresponding scale, avoiding blurry readings due to insufficient light; the light strip and the pointer point to the scale synchronously, focusing the illumination area and improving visual contrast.
[0057] When the LED strip is powered on, it emits light in the direction the pointer points, precisely illuminating the corresponding mark on the scale. At night or in dimly lit environments, operators can clearly observe the relative position of the pointer to the open / close reference without additional lighting, ensuring accurate operational judgment. The other parts of this embodiment are the same as those in the previous embodiment and will not be repeated here.
[0058] Example 7:
[0059] This embodiment further defines the mechanism of the mounting plate 1 based on the above embodiments, such as... Figures 1-3 As shown, the mounting plate 1 has several countersunk holes. This arrangement improves the overall stability of the device installation; the countersunk holes are used to accommodate the bolt heads, preventing the bolts from protruding from the surface of the mounting plate and preventing interference with other components; the bolts pass through the countersunk holes to firmly fix the mounting plate to the equipment, preventing the device from loosening due to vibration when the knife switch is operated, and ensuring the relative position of the pointer and the positioning block is stable.
[0060] During installation, the bolts pass through the countersunk holes and connect to the pre-set threaded holes on the equipment. The bolt heads are embedded in the countersunk holes, without affecting the sliding of components on the mounting plate surface (such as the transparent cover and positioning blocks). The even distribution of the countersunk holes (usually along the edge of the mounting plate) balances the forces on the mounting plate, making it less prone to deformation during long-term operation and ensuring the coaxiality of the rotating shaft and the transparent cover. Other parts of this embodiment are the same as those in the above embodiments and will not be repeated.
[0061] It is understood that the working principle and process of the GIS disconnector opening and closing position indication and monitoring device structure according to an embodiment of the present utility model, such as the pointer and light strip, are existing technologies and are well known to those skilled in the art, and will not be described in detail here.
[0062] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
