Description

Technical Field

[0001] The present disclosure relates to the field of power equipment, and in particular to a switch device. Background Art

[0002] Switchgear is widely used in the distribution system of power grid power supply, mainly for the functions of switching, controlling and protecting power transmission and distribution.

[0003] The circuit breaker is the core component of the switchgear, which is used to control the on and off of power. After the circuit breaker enters the cabinet of the switchgear, its position needs to be monitored or detected. Important positions include the test position and the working position. When the circuit breaker reaches the test position, its moving contact and the static contact are not connected, but the control line is connected. This position is used for fault simulation testing to test whether the circuit breaker works normally in the closed state and the middle position, and to ensure that the circuit breaker can respond normally under normal conditions. When the circuit breaker reaches the working position, the moving contact and the static contact are connected, allowing current to pass, ensuring the normal operation of the electrical equipment it powers. The test position, the working position, etc. are important positions for the normal operation and maintenance of the circuit breaker. With the development of science and technology, the accuracy requirements for monitoring important positions such as the test position and the working position are constantly improving.

[0004] However, switchgear usually uses a scale pasted on the motion trajectory to determine the position of the circuit breaker. This judgment method has low accuracy and often requires operators to rely on certain experience to determine whether the circuit breaker has moved to the correct position. Utility Model Content

[0065] In order to further illustrate the principle and structure of the present disclosure, preferred embodiments of the present disclosure are now described in detail with reference to the accompanying drawings.

[0066] As mentioned above, in the related technical field, a scale is usually pasted on the movement trajectory of the circuit breaker to display the position of the circuit breaker. It often requires operators to rely on certain experience to determine whether the circuit breaker has moved to the correct position. This judgment method has low accuracy.

[0067] In addition, since the distance from the bottom of the circuit breaker to the middle partition in the related technical field is very small, generally only about 7mm, the sensor installed under the middle partition can only use a small stroke sensor, but the effective stroke of the sensor is only within the range of 3-5mm, once vibration occurs during transportation or operation, it is easy to cause the sensor to fail. And the position indication accuracy of this sensor is not enough, the error may be about 10mm, which is easy to cause the plum blossom contact and the static contact to not bite in place.

[0068] like Figure 1 and Figure 2 As shown, the present application provides a switch device 1, which is provided with a position detection indicating device 10. The detection indicating device 10 is arranged below the horizontal partition 101 of the circuit breaker chamber. The horizontal partition 101 is provided with at least one through hole 1011. The position of the through hole 1011 is set according to the position reached by the circuit breaker 102. For example, a through hole 1011 is respectively arranged corresponding to the test position and the working position reached by the circuit breaker 102, that is, a corresponding through hole 1011 is arranged on the path where the circuit breaker 102 is located when it reaches the test position or the working position. Part of the structure of the detection indicating device 10 passes through the through holes 1011 and protrudes from the path where the circuit breaker 102 moves. When the circuit breaker 102 moves, pressure is applied to the part of the structure of the detection indicating device 10 that protrudes on the moving path of the circuit breaker 102, so that the detection indicating device 10 is activated to display or detect the current position of the circuit breaker 102, so that the staff can read the current position of the circuit breaker 102 to determine whether to perform the next operation, or the intelligent control module obtains corresponding information and determines whether to perform the next action based on the collected information.

[0069] For details, please refer to Figure 1 and Figure 2 The present application provides a switchgear 1, which includes a cabinet 100 and a plurality of components located in the cabinet 100, such as a circuit breaker 102. The cabinet 100 is provided with a plurality of functional rooms, such as a circuit breaker room 102a, an operation room or a cable room, etc. The circuit breaker can be an armored removable type, that is, the circuit breaker 102 can be moved or enter and exit the circuit breaker room 102a.

[0070] like Figure 2As shown, a horizontal partition 101 is provided at the bottom of the circuit breaker chamber 102a for separating the circuit breaker chamber 102a from the cable chamber. The circuit breaker 102 can be moved on the upper surface of the horizontal partition 101 by means of a guide rail or the like.

[0071] Combination Figure 3 As shown, the horizontal partition 101 includes a horizontal longitudinal portion 101a and a side portion 101b extending downward from the front end of the horizontal longitudinal portion 101a. The circuit breaker 102 moves along the longitudinal direction of the horizontal longitudinal portion 101a. The side portion 101b is parallel to the front door of the cabinet 100.

[0072] A viewing window 1012 is provided on the side portion 101b in the direction toward the front door, through which the label displayed on the indicator board of the position detection indicating device 10 can be observed. The label can be a color label of a different color, a text label, or a color label with text. For example, the indicator board is provided with three groups of text labels, namely remove, test, and service, which respectively represent the three positions of the circuit breaker, namely the removal position, the test position, and the working position. If the staff sees the text label of test through the viewing window 1012, it means that the circuit breaker has reached the test position; if the staff sees the text label of service, it means that the circuit breaker has reached the working position; if the staff sees the text label of remove, it means that the circuit breaker has not yet entered the circuit breaker room.

[0073] It should be noted that the front and rear directions referred to in this application are based on the direction in which the cabinet is in normal use. For example, when the cabinet is in normal use, the direction in which the front door is located is defined as the front, and the direction in which the rear door is located is defined as the rear.

[0074] like Figure 4 As shown, a position detection indicating device 10 is provided below the horizontal partition 101. The position detection indicating device 10 includes a main mounting plate 11, at least one transmission assembly and an indicator sign 14. The main mounting plate 11 includes a longitudinal portion 111 and a transverse mounting portion 112 perpendicular to the longitudinal portion 111. The longitudinal portion 111 extends in the front-to-back direction, and the transverse mounting portion 112 is close to the lower surface of the horizontal partition 101 and is mounted on the lower surface of the horizontal partition 101 by means of fixing members such as screws or bolts. The transmission device is mounted on the main mounting plate 11. At least part of the transmission assembly corresponds to a through hole 1011 passing through. The indicator sign 14 is connected to the transmission assembly, and when the circuit breaker 102 passes through the through hole 101, the portion of the transmission assembly protruding from the through hole 1011 is pressed down, driving the indicator sign 14 to move.

[0075] The transmission assembly can be set to one or more, and the number of the transmission assemblies corresponds to the number of the detection position points. For example, two transmission assemblies are set, one of which is used to detect the test position of the circuit breaker, and the other transmission assembly is used to detect the working position of the circuit breaker.

[0076] In this embodiment, the present application includes two transmission assemblies, namely a first transmission assembly 12 and a second transmission assembly 13, which are respectively used to detect the test position and the working position of the circuit breaker.

[0077] Correspondingly, two through holes 1011 are provided on the horizontal partition 101, namely, a first through hole 1011a and a second through hole 1011b. The first through hole 1011a and the second through hole 1011b are located on the moving path of the circuit breaker 102 and are spaced apart from each other by a predetermined distance. The predetermined distance is set according to the electrical position reached by the circuit breaker 101 to ensure that when the circuit breaker 102 passes through the position of the first through hole 1011a, the circuit breaker 102 reaches the test position, and when the circuit breaker 102 passes through the position of the second through hole 1011b, the circuit breaker 102 reaches the working position.

[0078] like Figure 5 As shown, the first transmission assembly 12 includes a first cam 121 and a first seesaw 122. The first seesaw 122 is mounted on one side of the longitudinal portion 111 of the main mounting plate 11 by a connecting member such as a bolt. Both ends of the first seesaw 122 can swing up and down relative to a fulcrum 1224 of the main mounting plate 11. The first cam 121 is located above the first end of the first seesaw 122 away from the sign 14. When the first cam 121 rotates downward, a downward pressure is applied to the first end of the first seesaw 122, and the second end of the first seesaw 122 tilts upward relative to the fulcrum 1224, driving the sign 14 to move upward.

[0079] The first cam 121 is mounted on the longitudinal portion 111 of the main mounting plate 11 through the first reset shaft 125. The first cam 121 can rotate relative to the first reset shaft 125 under the action of external force. In the absence of external force, the first cam 121 passes through the first through hole 1011a of the horizontal partition 101 and protrudes from the upper surface of the horizontal partition 101. In this way, when the circuit breaker 102 moves on the horizontal partition 101, it can step on the first cam 121 and apply downward pressure to the first cam 121.

[0080] The first cotter pin 126 passes through the top of the first reset shaft 125. The first reset torsion spring 124 is sleeved on the first reset shaft 125 and is located between the first cotter pin 126 and the first cam 121. The first cam positioning shaft 123 is installed on the first cam 121 and is parallel to the first reset shaft 125. One end of the first reset torsion spring 124 is fixed to the first cotter pin 126, and the other end is located between the first reset shaft 125 and the first cam positioning shaft 123. The other end of the first reset torsion spring 124 extends from the first reset shaft 125 to the direction of the first cam positioning shaft 123, and the height exceeds the first cam positioning shaft 123, and forms a hook shape. When the first cam 121 is rotated toward the direction of the first reset torsion spring 124 under the pressure of the circuit breaker 102, the first cam positioning shaft 123 pushes the first reset torsion spring 124, so that the first reset torsion spring 124 is compressed in the direction of the first seesaw 122.

[0081] When the first cam 121 is not subjected to the pressure of the circuit breaker 102 , the first reset torsion spring 124 is reset to reverse the first cam 121 and restore it to its original state.

[0082] The first micro switch 127 is mounted on the main mounting plate 11 and is located on the same side as the first seesaw 122. The first micro switch 127 is located on the downward movement path of the first end of the first seesaw 122, and is used to generate a first position electrical signal when the circuit breaker 102 reaches the test position, and send it to the intelligent control module, and the intelligent control module determines whether to execute the next action according to the first position signal.

[0083] The first end of the first seesaw 122 has a special-shaped cutout 1221, and the special-shaped cutout 1221 is directly opposite to the first micro switch 127. When the first cam 121 rotates downward, the first end of the first seesaw 122 is driven to move downward, and the special-shaped cutout 1221 of the first seesaw 122 cooperates with the first micro switch 127, so that one end of the first seesaw 122 touches the first micro switch 127 to generate a first position electrical signal. The first position signal is sent to the intelligent control module.

[0084] The first micro switch 127 has a cylindrical travel rod 1271. The first end of the first seesaw 127 forms a first arc surface 1222 at the special-shaped cutout 1221. The shape of the first arc surface 1222 is adapted to the shape of the travel rod 1271 of the first micro switch 127. In this way, the first end of the first seesaw 122 can accurately match the first micro switch 127 to accurately control the triggering of the first micro switch 127. It is ensured that when the circuit breaker reaches the test position, the corresponding signal can be accurately triggered.

[0085] The first micro switch 127 is fixed to the two mounting holes of the main mounting plate 11 by two fasteners. The two mounting holes are concentrically arranged, that is, the two mounting holes are located on a circumference with the same axis as the center (i.e., the fulcrum 1224). In this way, during the installation and adjustment process, the position of the first micro switch 127 can be easily adjusted, and at the same time, the first seesaw 12 makes a circular motion along the axis where the fulcrum 1224 is located, thereby ensuring that it can accurately respond to the movement of the circuit breaker.

[0086] The first transmission assembly 12 and the second transmission assembly 13 are respectively disposed on opposite sides of the main mounting plate 11. Figure 6 As shown, the second transmission assembly 13 includes a second cam 131 and a second seesaw 132. The second seesaw 132 is mounted on the other side of the longitudinal portion 111 of the main mounting plate 11 by a connecting member such as a bolt. Both ends of the second seesaw 132 can swing up and down relative to a fulcrum 1324 of the main mounting plate 11. The second cam 131 is located above the first end of the second seesaw 132 away from the sign 14. When the second cam 131 rotates downward, a downward pressure is applied to the first end of the second seesaw 132, and the second end of the second seesaw 132 tilts upward relative to the fulcrum 1324, driving the sign 14 to move upward.

[0087] The second cam 131 is mounted on the longitudinal portion 111 of the main mounting plate 11 through the second reset shaft 135. The second cam 131 can rotate relative to the second reset shaft 135 under the action of external force. In the absence of external force, the second cam 131 passes through the second through hole 1011b of the horizontal partition 101 and protrudes from the upper surface of the horizontal partition 101. In this way, when the circuit breaker 102 moves on the horizontal partition 101, it can step on the second cam 131 and apply downward pressure to the second cam 131.

[0088] The second cotter pin 136 passes through the top of the second reset shaft 135. The second reset torsion spring 134 is sleeved on the second reset shaft 135 and is located between the second cotter pin 136 and the second cam 131. The second cam positioning shaft 133 is installed on the second cam 131 and is parallel to the second reset shaft 135. One end of the second reset torsion spring 134 is fixed on the second cotter pin 136, and the other end is located between the second reset shaft 135 and the second cam positioning shaft 133. The other end of the second reset torsion spring 134 extends from the second reset shaft 135 to the direction of the second cam positioning shaft 133, and the height exceeds the second cam positioning shaft 133, and forms a hook shape. When the second cam 131 is rotated toward the direction of the second reset torsion spring 134 under the pressure of the circuit breaker 102, the second cam positioning shaft 133 pushes the second reset torsion spring 134, so that the second reset torsion spring 134 is compressed in the direction of the second seesaw 132.

[0089] When the second cam 131 is not subjected to the pressure of the circuit breaker 102 , the second reset torsion spring 134 is reset to reverse the second cam 131 and restore it to its original state.

[0090] The second micro switch 137 is mounted on the main mounting plate 11 and is located on the same side as the second seesaw 132. The second micro switch 137 is located on the downward movement path of the first end of the second seesaw 132, and is used to generate a second position electrical signal when the circuit breaker 102 reaches the test position, and send it to the intelligent control module, and the intelligent control module determines whether to execute the next action according to the second position signal.

[0091] The first end of the second seesaw 132 has a special-shaped cutout 1321, and the special-shaped cutout 1321 is directly opposite to the second micro switch 137. When the second cam 131 rotates downward, the first end of the second seesaw 132 is driven to move downward, and the special-shaped cutout 1321 of the second seesaw 132 cooperates with the second micro switch 137, so that one end of the second seesaw 132 touches the second micro switch 137 to generate a second position electrical signal. The second position signal is sent to the intelligent control module.

[0092] The second micro switch 137 has a cylindrical travel rod 1371. The first end of the second seesaw 137 forms a second arc surface 1322 at the special-shaped cutout 1321. The shape of the second arc surface 1322 matches the shape of the travel rod 1371 of the second micro switch 127. In this way, the first end of the second seesaw 132 can accurately match the second micro switch 137 to accurately control the triggering of the second micro switch 137. It is ensured that when the circuit breaker reaches the test position, the corresponding signal can be accurately triggered.

[0093] The second micro switch 137 is fixed to the two mounting holes of the main mounting plate 11 by two fasteners. The two mounting holes are concentrically arranged, that is, the two mounting holes are located on a circumference with the same axis as the center (that is, the fulcrum 1324). In this way, during the installation and adjustment process, the position of the second micro switch 137 can be easily adjusted, and at the same time, the second seesaw 13 makes a circular motion along the axis where the fulcrum 1324 is located, thereby ensuring that it can accurately trigger the second micro switch to respond to the movement of the circuit breaker.

[0094] The second ends of the first seesaw 122 and the second seesaw 132 are connected to the indicator board 14. When the first seesaw 122 and the second seesaw 132 are tilted up or down, the indicator board 14 is driven to move.

[0095] like Figure 6 and Figure 7As shown, the sign 14 includes a sign panel 141 and a hanging plate 142. The sign panel 141 has a first surface facing the first seesaw 122 and the second seesaw 132. The first surface is provided with a slot 143 that cooperates with the first seesaw 122 and the second seesaw 132. The slot 143 extends in the vertical direction of the sign panel 141. Figure 8 As shown, the slot 143 can be formed by a plurality of plate-like structures extending from the first surface to the seesaw direction. The second ends of the first seesaw 122 and the second seesaw 132 can be inserted into the corresponding slots 143 from bottom to top. The number of slots 143 depends on the number of seesaws. In this embodiment, there are two seesaws, and two slots 143 are correspondingly provided. The second surface of the indicator panel 141 has a label 144 facing the front door of the cabinet. The label 144 is divided into three sections, each of which is correspondingly affixed with text and / or color labels for displaying different positions. For example, these three sections are correspondingly displayed as working position, test position and removal position. The viewing window 1012 of the horizontal partition 101 is opposite to the area to be displayed on the indicator 14, that is, the label segment on the area to be displayed can be observed through the viewing window 1012 of the horizontal partition 101, that is, as the indicator panel 141 moves, labels with different contents can be seen through the viewing window 1012. In this way, it is convenient for staff to observe the position information on the label.

[0096] like Figure 6 and Figure 7 As shown, the side portion 101b of the horizontal partition 101 is provided with an indicator rail 15. Both sides of the indicator 14 can move up and down along the indicator rail 15. The bottom of the indicator rail 15 has a lower limit plate 151. One end of the indicator reset tension spring 16 is connected to the lower limit plate 151, and the other end is connected to the indicator 14. When the indicator 14 moves upward under the action of the first seesaw 122 and the second tilting plate 123 (or the first seesaw), the indicator reset tension spring 16 is stretched. When the first seesaw 122 and the second tilting plate 123 lose external force, the indicator reset tension spring 16 is reset to pull the first seesaw 122 and the second tilting plate 123 back to their original positions.

[0097] The signboard reset tension spring 16 installed on the signboard 14 is used to reset the signboard 14. The first cam 121 and the second cam 131 are correspondingly provided with the first reset torsion spring 124 and the second reset torsion spring 134. The tops of the first reset shaft 125 and the second reset shaft 135 are both provided with angled through holes, and the first cotter pin 126 and the second cotter pin 136 are respectively fixed on the corresponding reset shafts through the corresponding angled through holes. The first cotter pin 126 and the second cotter pin 136 drive their respective torsion springs to rotate. In this way, the preload force of the torsion spring is ensured, and at the same time, when the first cam and the second cam are not subjected to external forces, the signboard 14 can quickly return to its original position. In addition, the rear end of the reset shaft provided with an angled groove cooperates with the angled groove hole on the main mounting plate 11, so as to ensure the accuracy of welding.

[0098] like Figures 9 to 11 As shown, when the circuit breaker 102 reaches the test position, the circuit breaker 102 presses down the first cam 121, and the first cam 121 rotates downward, driving the first end of the first seesaw 122 to move downward and touch the micro switch 127. The second end of the first seesaw 122 tilts upward, driving the indicator 14 to move upward by a first distance d1. At this time, when the circuit breaker 102 has not reached the position of the second cam 131, the first cam 131 does not rotate, and the second micro switch 137 is not triggered. At this time, the second section 144b of the label 144 can be observed through the inspection port 1012. The second section 144b can display text, for example, test (test position).

[0099] like Figure 12 to Figure 14 As shown, when the circuit breaker 102 reaches the working position, the circuit breaker 102 simultaneously presses down the first cam 121 and the second cam 131. The first cam 121 rotates downward, driving the first end of the first seesaw 122 to move downward and touch the first micro switch 127. The second cam 131 rotates downward, driving the first end of the second seesaw 132 to move downward and touch the second micro switch 137. The second ends of the first seesaw 122 and the second seesaw 132 tilt upward, driving the indicator 14 to move upward by a second distance d2. At this time, the third section 144c of the label 144 can be observed through the inspection port 1012. The third section 144c can display text, such as service (working position).

[0100] The distance that the indicator 14 moves can be achieved by adjusting the lever transmission ratio of the seesaw. For example, the lever transmission ratio of the first seesaw 122 is 1:1, that is, the distance between the first end and the second end of the first seesaw 12 relative to the fulcrum 1224 is 1:1. In this way, if the distance that the first end of the first seesaw 12 moves downward is 1 cm, then the distance that the second end of the first seesaw 12 tilts upward is 1 cm. The lever transmission ratio of the second seesaw 132 is 1:2, and the distance between the first end and the second end of the second seesaw 13 relative to the fulcrum 1324 is 1:2. In other words, if the distance that the first end of the second seesaw 13 moves downward is 1 cm, then the distance that the second end of the second seesaw 13 tilts upward is 2 cm. In this way, when the second seesaw 13 needs to travel an empty distance in the slot 143, the distance that the indicator 14 needs to move is also met.

[0101] like Figure 6 As shown, when the circuit breaker 102 does not enter the circuit breaker chamber, the first cam 121 and the second cam 131 do not move, and the indicator 14 does not move. At this time, the first section 144a of the label 144 can be observed through the inspection port 1012. The first section 144a can display text, for example, remove.

[0102] In some embodiments, Figures 15 to 17 As shown, the first cam 121 may also be provided with a first roller 128 for reducing the contact friction between the first cam 121 and the first seesaw 122. The first roller 128 is installed at the end of the first cam 121 close to the first seesaw 122 through a mounting shaft. When the first cam 121 rotates downward, the first roller 128 rolls in contact with the first end of the first seesaw 122, and drives the first end of the first seesaw 122 to move downward.

[0103] Similar, such as Fig.18 As shown, the second cam 131 may also be provided with a second roller 138 for reducing the contact friction between the second cam 131 and the second seesaw 132. The second roller 138 is installed at the end of the second cam 131 close to the second seesaw 132 through the installation shaft. When the second cam 131 rotates downward, the second roller 138 rolls in contact with the first end of the second seesaw 132, and drives the first end of the second seesaw 132 to move downward.

[0104] In summary, as mentioned above, the transmission assembly of the present application sets corresponding protrusions according to different positions of the circuit breaker, such as the first cam and the second cam. When the circuit breaker reaches different positions, the circuit breaker applies pressure to different protrusions, so that the indicator moves different distances, so that different positions of the indicator can be observed, and different indications of different positions are achieved. And the indicator is driven by the transmission assembly, and the corresponding position information is displayed on the indicator, so as to achieve accurate indication of the position of the circuit breaker.

[0105] In addition, the detection method of the present application can also be applied to intelligent switch equipment, by touching the micro switch with a seesaw, the relevant position information of the circuit breaker is sent to the intelligent control module. Since the micro switch is set on the main mounting plate, there is sufficient installation space, and the micro switch is not limited by its size and stroke, a micro switch with a large stroke can be selected, thereby improving the effectiveness of the detection and the accuracy of the position detection.

[0106] The above are only preferred feasible embodiments of the present disclosure and are not intended to limit the protection scope of the present disclosure. All equivalent structural changes made using the contents of the present disclosure and the drawings are included in the protection scope of the present disclosure.
