[0035] The utility model discloses an embodiment proposes a kind of knife switch state acquisition device 100, it is applied to knife switch device, for detecting the opening and closing state of knife switch, it can be understood here, the knife switch equipment refers to GIS (GAS INSULATED SWITCHGEAR, gas insulation fully enclosed combination electrical apparatus).The knife switch equipment is existing structure, not one by one here. Knife switch device includes the output shaft 200 of rotation setting, the output shaft 200 is used to output the movement when knife switch device operates, and can be connected with knife switch state acquisition device 100, to convert mechanical action into electrical signal. Please refer to Figures 1 to 4 In the embodiment, the knife switch state acquisition device 100 includes a mounting assembly, a transmission disc 20, a driving member 30, a sensing member 40, and a detection member 50.

[0036] The mounting assembly is fixedly installed on the knife switch device, and the mounting assembly is provided with an annular mounting portion 121. The mounting assembly can be fixedly connected with the knife switch device by a hoop 111, a steel cable, or the like, to stably fix the mounting assembly on the knife switch device and provide a stable installation environment for other components installed on the mounting assembly.

[0037] The transmission disc 20 is rotatably installed on the mounting assembly, and the transmission disc 20 is coaxially arranged with the annular mounting portion 121. The transmission disc 20 can be rotatably installed on the mounting assembly in various ways. In some examples, the transmission disc 20 is rotatably installed on the mounting assembly by a bearing. In other examples, the mounting assembly is provided with a cylindrical groove, and the transmission disc 20 is rotatably installed on the groove by a rotating shaft. The transmission disc 20 is coaxially arranged with the annular mounting portion 121, which means that the axis of rotation of the transmission disc 20 coincides with the axis of the annular mounting portion 121.

[0038] The driving member 30 is fixedly installed on the output shaft 200 of the knife switch device and is in transmission connection with the transmission disc 20. The driving member 30 can be fixedly installed on the output shaft 200 in various ways, such as threaded connection, welding, riveting, key connection, or the like. The driving member 30 can be in transmission connection with the transmission disc 20 in various ways, such as through the meshing of a gear or the meshing of a toothed chain. Specifically, in an example, the driving member 30 can be in transmission connection with the transmission disc 20 through a reduction gear set. It can be understood that when the knife switch device operates, the output shaft 200 will rotate relatively, at which time the output shaft 200 can synchronously drive the driving member 30 to rotate, and the driving member 30 drives the transmission disc 20 to rotate.

[0039] The inductive element 40 is fixedly installed on the transmission disc 20 to rotate with the transmission disc 20 when the driving element 30 drives the transmission disc 20 to rotate. The inductive element 40 can be fixedly installed on the transmission disc 20 in various ways. In some examples, the inductive element 40 is fixedly installed on the transmission disc 20 by means of non-detachable connection, for example, by means of adhesion. In some examples, the inductive element 40 is fixedly installed on the transmission disc 20 by means of detachable connection, for example, by means of screw connection or clamping.

[0040] It can be understood that the inductive element 40 rotates with the transmission disc 20, and the rotating path of the inductive element 40 is a circular ring coaxial with the transmission disc 20, and the transmission disc 20 is coaxial with the annular mounting portion 121, that is, the rotating path of the inductive element 40 is coaxial with the annular mounting portion 121.

[0041] It should be emphasized that, in the present example, the knife switch state acquisition device 100 converts the rotation of the output shaft 200 into the rotation of the transmission disc 20 by means of the driving element 30 and the like, and limits the rotation angle of the transmission disc 20 to one circle by means of the transmission ratio.

[0042] The detection element 50 is detachably installed at any position of the annular mounting portion 121, and the detection element 50 is used to detect the inductive element 40. It can be understood that the detection element 50 can determine the rotation angle of the inductive element 40 and the transmission disc 20 by detecting the inductive element 40, and the rotation angle of the driving element 30 and the output shaft 200 can be indirectly obtained according to the transmission ratio relationship between the transmission disc 20 and the driving element 30. In this way, the knife switch state acquisition device 100 can convert the mechanical movement of the output shaft 200 into an electrical signal of the knife switch state acquisition device 100.

[0043] Common knife switch devices include single-phase disconnectors and three-phase disconnectors. The knife switch state acquisition device 100 applied to the single-phase disconnector needs to output the closing signal and the opening signal within one rotation of the transmission disc 20, that is, the transmission disc 20 outputs the opening signal or the closing signal within 180° or 180°. In different single-phase disconnectors, the output shaft 200 of some knife switch devices drives the transmission disc 20 to rotate by 100° to make the knife switch state acquisition device 100 output the opening signal or the closing signal, and the output shaft 200 of some other knife switch devices drives the transmission disc 20 to rotate by 180° to make the knife switch state acquisition device 100 output the opening signal or the closing signal. Here, no further examples are given.

[0044] Similarly, the switch state acquisition device 100 applied to the three-phase disconnector needs to output the signal of the closing of the switch and the opening of the ground switch, the signal of the closing of the switch and the opening of the ground switch, and the signal of the opening of the switch and the closing of the ground switch within one rotation of the transmission disc 20, that is, the transmission disc 20 outputs the signal of the closing of the switch and the opening of the ground switch, the signal of the closing of the switch and the opening of the ground switch, or the signal of the opening of the switch and the closing of the ground switch within 120° or 120°. In different three-phase disconnectors, the output shaft 200 of some switch devices drives the transmission disc 20 to rotate 90° to make the switch state acquisition device 100 output a signal once, and the output shaft 200 of some other switch devices drives the transmission disc 20 to rotate 120° to make the switch state acquisition device 100 output a signal once.

[0045] The switch state acquisition device 100 usually includes three detection pieces 50. When the switch state acquisition device 100 is applied to a three-phase disconnector, one detection piece 50 is arranged at the position of the inductor 40 when the switch device is in the state of the closing of the switch and the opening of the ground switch, one detection piece 50 is arranged at the position of the inductor 40 when the switch device is in the state of the closing of the switch and the opening of the ground switch, and one detection piece 50 is arranged at the position of the inductor 40 when the switch device is in the state of the opening of the switch and the closing of the ground switch. In this way, when the corresponding detection piece 50 detects the inductor 40, the angle of rotation of the inductor 40 and the transmission disc 20 can be determined, and the current state of the switch device can be determined, and the corresponding electrical signal can be output.

[0046] When the switch state acquisition device 100 is applied to a single-phase disconnector, the switch state acquisition device 100 can also include three detection pieces 50. One detection piece 50 is arranged at the position of the inductor 40 when the switch device is in the state of the opening, one detection piece 50 is arranged at the position of the inductor 40 when the switch device is in the state of the closing, and the remaining one detection piece 50 is arbitrarily installed on the annular mounting portion 121, but is not used, serving as a spare piece to be replaced when other detection pieces 50 are damaged, or the remaining one detection piece 50 is used to detect whether the inductor 40 is overstroke.

[0047] The cutter switch state acquisition device 100 provided by the embodiments of the present application can be applied to different cutter switch devices. When the cutter switch device is in a switching state, the detection piece 50 can be disassembled from the annular mounting portion 121. Then, according to the transmission ratio relationship between the transmission disc 20 and the driving piece 30, the angle through which the output shaft 200 drives the transmission disc 20 to rotate is determined when the driving piece 30 drives the transmission disc 20 to rotate. The detection piece 50 is reinstalled at the corresponding position of the annular mounting portion 121. After the cutter switch device is in the switching state, that is, after the output shaft 200 drives the transmission disc 20 to rotate by a fixed angle, the detection piece 50 can be triggered by the inductor 40, so that the cutter switch state acquisition device 100 can be applied to different cutter switch devices, and the application range of the cutter switch state acquisition device 100 is increased.

[0048] In some examples, as shown in Figure 2 and Figure 3 , the annular mounting portion 121 includes an elongated hole extending along the circumference of the transmission disc 20, and the detection piece 50 is fixed to any position of the elongated hole by a screw structure. In this way, the screw structure can be loosened to drive the detection piece 50 to move along the extension direction of the elongated hole. After being adjusted to the corresponding position, the screw structure can be tightened again. In this way, the specific position of the detection piece 50 can be quickly adjusted, and the operation efficiency of the operator is improved.

[0049] In some examples, the annular mounting portion 121 includes an annular guide rail coaxially arranged with the transmission disc 20, and the detection piece 50 is fixed to any position of the annular guide rail by a clamp. In this way, the specific position of the detection piece 50 can be quickly adjusted, and the operation efficiency of the operator is improved.

[0050] In some examples, as shown in Figure 2 and Figure 3 , the mounting assembly includes a fastener 11, a mounting plate 12, and a locking piece 13. The fastener 11 is fixedly connected with the cutter switch device. The mounting plate 12 is rotationally installed with the transmission disc 20. The mounting plate 12 is slidingly installed on the fastener 11. The mounting plate 12 moves relative to the fastener 11 to drive the transmission disc 20 to move towards or away from the driving piece 30. The locking piece 13 is used to lock the mounting plate 12 to the fastener 11.

[0051] It can be understood that the above-mentioned annular mounting portion 121 can be arranged on the mounting plate 12, that is, the elongated hole and / or the annular guide rail can be arranged on the mounting plate 12.

[0052] In this way, the transmission relationship between the transmission disc 20 and the driving member 30 can be adjusted to improve the installation accuracy of the knife gate state acquisition device 100. For example, when the transmission disc 20 is connected with the driving member 30 through the meshing of the gear, the transmission disc 20 can be driven to move towards the driving member 30 to make the meshing more closely. For another example, when the transmission disc 20 is connected with the driving member 30 through the meshing of the toothed chain, the transmission disc 20 can be driven to move away from the driving member 30 to tension the toothed chain.

[0053] Preferably, the driving member 30 comprises a gear, which is connected with the transmission disc 20 in a transmission mode, i.e., the gear is connected with the transmission disc 20 through meshing and can transmit power through the connection.

[0054] In some examples, as shown in Figure 2 and Figure 3 , the fastener 11 comprises a hoop 111 and a fixed plate 112, the hoop 111 is fixedly connected with the knife gate device, one side of the fixed plate 112 is fixedly connected with the hoop 111, and the fixed plate 112 is slidingly installed with the mounting plate 12. In this way, the knife gate state acquisition device 100 can be installed on the knife gate device, and the hoop 111 is usually a standard part that can be directly purchased on the market, thereby reducing the manufacturing cost of the knife gate state acquisition device 100.

[0055] In some examples, as shown in Figure 2 and Figure 3 , the fixed plate 112 is provided with a sliding hole 113 extending in the direction close to the driving member 30, the mounting plate 12 is fixedly provided with a sliding column 122, and the mounting plate 12 is slidingly installed in the sliding hole 113 through the sliding column 122.

[0056] Considering the stability between the mounting plate 12 and the fixed plate 112, the number of the sliding hole 113 and the sliding column 122 is usually multiple, and in the example shown in Figure 3 , the fixed plate 112 is provided with four sliding holes 113, and the mounting plate 12 is slidingly installed in the four sliding holes 113 through four sliding columns 122. In this way, the stability of the sliding of the mounting plate 12 relative to the fixed plate 112 can be improved.

[0057] In some examples, as shown in Figure 2 and Figure 3 , the mounting plate 12 is provided with a locking hole 123, the extension direction of the locking hole 123 is parallel to the sliding direction of the mounting plate 12 relative to the fastener 11, and the locking member 13 comprises a bolt which is threadedly connected with the fixed plate 112 through the locking hole 123. In this way, the mounting plate 12 and the fixed plate 112 can be locked through the bolt.

[0058] In some examples, asFigures 1 to 3 As shown in the figure, the transmission disc 20 is rotatably installed on the side of the mounting plate 12 away from the fixed plate 112, and the mounting plate 12 and the fixed plate 112 are both provided with an escape hole 124, and the output shaft 200 passes through the escape hole 124 and is fixedly connected with the driving member 30. The mounting assembly further comprises a cover body 14 fixedly connected with the mounting plate 12 to form a containing cavity containing the transmission disc 20 and the driving member 30. In this way, the parts of the knife gate state acquisition device 100 are protected by the cover body 14, which can effectively prevent external interference during normal operation after installation.

[0059] In some examples, as shown in the figure, Figures 2 to 4 As shown in the figure, the transmission disc 20 comprises a connecting shaft 21, a connecting arm 22 and a transmission ring 23, the connecting shaft 21 is rotatably installed on the mounting assembly, one end of the connecting arm 22 is fixedly connected with the connecting shaft 21, and the other end of the connecting arm 22 is fixedly connected with the transmission ring 23. In this way, the weight of the transmission disc 20 is reduced to reduce the driving resistance of the driving member 30 to drive the transmission disc 20 to rotate, and considering the reliability of the connection between the transmission ring 23 and the connecting shaft 21, the number of connecting arms 22 is usually three.

[0060] In some examples, as shown in the figure, Figures 2 to 4 As shown in the figure, the connecting arm 22 extends along the radial direction of the transmission ring 23, the connecting arm 22 is provided with a mounting hole 221 extending along the radial direction of the transmission ring 23, and the inductive member 40 is fixedly connected to any position of the mounting hole 221 by a screw structure. In this way, the inductive member 40 is adjusted to improve the detection accuracy of the detection member 50 to the inductive member 40.

[0061] According to different detection principles, there are many types of inductive members 40 and detection members 50, in some examples, the inductive member 40 and the detection member 50 realize detection by air detection, for example: the inductive member 40 comprises a magnetic steel, and the detection member 50 comprises a magnetic induction sensor; in some examples, the inductive member 40 and the detection member 50 realize detection by direct mechanical contact, for example: the inductive member 40 comprises a solid trigger block, and the detection member 50 comprises a micro switch.

[0062] The above is only an optional embodiment of the present application, and does not limit the patent scope of the present application, any equivalent structural transformation made by the contents of the present application and the drawings, or direct / indirect application in other related technical fields within the concept of the present application are included in the patent protection scope of the present application.
