Description

Technical Field

[0001] This utility model belongs to the technical field of overhead contact line closing equipment, specifically relating to a device for identifying the closing status of an overhead contact line disconnector switch. Background Technology

[0002] In recent years, my country's electrified railway construction has accelerated, with high-speed railways becoming the leader in my country's electrified railway system. The reliable power supply of the high-speed railway traction power supply system has become an important part of ensuring railway transportation safety. Once a traction power supply failure occurs and reclosing fails, controlling the power supply of small units through remote disconnect switches becomes the key to isolating fault points and small-scale power outages in high-speed railways. Whether the opening and closing status of the disconnect switches meets the requirements is of paramount importance for isolating fault points and small-scale power outages.

[0003] The existing method for determining the open / closed position of disconnecting switches mainly relies on auxiliary contacts located within the switch's mechanism housing and connected to the switch's transmission mechanism. The open / closed position is inferred from the displacement of these transmission components. However, the auxiliary contacts are separated from the actual contacts by a considerable distance. If the transmission mechanism malfunctions, the open / closed position output by the auxiliary contacts will not match the actual contact position, leading to misjudgment and leaving the disconnecting switch contacts in a partially closed state. This can result in poor contact, causing the disconnecting switch to overheat or discharge, seriously threatening equipment and power grid safety. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; of course, they can also refer to a mechanical connection or an electrical connection; furthermore, they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0030] like Figure 1-8 As shown, the present invention provides a device for identifying the closed state of a contact network disconnector switch, comprising a column 1, a drive device 2, and a mounting box 3. Its features include a base 4 on top of the column 1, a stationary contact 5 on the base 4 and connected to a power supply cable, a moving contact 6 on the base 4 and connected to the contact network, an isolating switch 7 hinged to the moving contact 6 for connecting to the stationary contact 5, a transmission mechanism rotatably mounted on the base 4, one end hinged to the drive device 2 and the other end hinged to the isolating switch 7, a closing detection mechanism on the base 4 for detecting the closed state of the isolating switch 7, a position detection mechanism on the base 4 for detecting the position of the isolating switch 7, and a control mechanism located in the mounting box 3 and connected to the closing detection mechanism and the position detection mechanism respectively.

[0031] This utility model has a simple structure, a scientific and reasonable design, and is easy to use. By cooperating with the closing detection mechanism and the position detection mechanism, this utility model can easily confirm the closing or opening status of the isolating switch 7. At the same time, the closing detection mechanism can further detect the closing status, thereby reducing the possibility of the isolating switch 7 not closing properly. Meanwhile, the operator can further determine the closing position of the isolating switch according to the screen 23.

[0032] The mounting box 3 of this utility model is mounted on the column 1, and the driving device 2 is mounted inside the mounting box 3 and connected to the transmission mechanism. In use, the driving device 2 drives the transmission shaft 24 to rotate, which in turn drives the hinge plate 25 to rotate. The hinge plate 25 then drives the third insulating column 26 to rotate. During rotation, the third insulating column 26 drives the isolating switch 7 to rotate, causing the isolating switch 7 to separate from or connect to the stationary contact 5. When the isolating switch 7 is closed, it is positioned between the two detection boxes 8. As the isolating switch 7 moves, it presses against the trigger rod 13, causing it to slide within the clearance hole 16 and press against the reset spring 15, thus disengaging the trigger rod 13 from the pressure transmission mechanism. When the pressure sensor 10 contacts the trigger rod 13, it detects the pressure applied by the trigger rod 13 and transmits the detection result to the microprocessor 22. The microprocessor 22 controls the opening indicator 12 or closing indicator 11 to light up according to the pressure value of the pressure sensor 10, so that the back-end operator and the on-site operator can understand the opening status of the isolating switch 7. At the same time, after closing or opening, the camera 21 collects the image between the isolating switch 7 and the stationary contact 5 and transmits the collected image to the microprocessor 22. The microprocessor 22 transmits the collected image to the host computer and the display screen 23. The on-site operator can further confirm the closing or opening status of the isolating switch 7 through the image displayed on the display screen 23.

[0033] Meanwhile, during routine maintenance, back-end personnel can observe the closing status of the isolating switch 7 through the screen displayed on the host computer and the pressure value detected by the pressure sensor 10, thereby preventing the isolating switch 7 from becoming loose during use, which facilitates the maintenance and repair of the contact network isolating switch. Example

[0034] like Figure 1-8 As shown, the present invention provides a device for identifying the closed state of a contact network disconnector switch, comprising a column 1, a drive unit 2, and a mounting box 3, and further comprising a base 4 on top of the column 1, a stationary contact 5 on the base 4 and connected to a power supply cable, a moving contact 6 on the base 4 and connected to the contact network, an isolating switch 7 hinged to the moving contact 6 for connecting to the stationary contact 5, a transmission mechanism rotatably mounted on the base 4, one end hinged to the drive unit 2 and the other end hinged to the isolating switch 7, a closing detection mechanism on the base 4 for detecting the closed state of the isolating switch 7, a position detection mechanism on the base 4 for detecting the position of the isolating switch 7, and a control mechanism located in the mounting box 3 and connected to the closing detection mechanism and the position detection mechanism respectively.

[0035] The closing detection mechanism includes a detection box 8 located on the base 4 and on both sides of the stationary contact 5, a trigger mounting seat 9 located in the detection box 8, a pressure sensor 10 located on the trigger mounting seat 9 and connected to the control mechanism, a trigger mechanism located in the detection box 8 for opening the pressure sensor 10, and a closing indicator light 11 and a closing indicator light 12 located in the mounting box 3.

[0036] In this embodiment 2, the detection box 8 can easily protect the pressure sensor 10. When the isolating switch 7 is closed, when the isolating switch 7 contacts the stationary contact 5, the isolating switch 7 will squeeze the trigger mechanism, thereby making the trigger mechanism contact the pressure sensor 10, the pressure sensor 10 will open, and the signal of the pressure sensor 10 opening will be transmitted to the microprocessor 22. The microprocessor 22 controls the closing indicator light 11 to light up, so that the operator can determine whether the isolating switch 7 is closed in place by observing the closing indicator light 11.

[0037] The pressure sensor 10 of this utility model is a pressure sensor. Example

[0038] like Figure 1-8 As shown, the present invention provides a device for identifying the closed state of a contact network disconnector switch, comprising a column 1, a drive unit 2, and a mounting box 3, and further comprising a base 4 on top of the column 1, a stationary contact 5 on the base 4 and connected to a power supply cable, a moving contact 6 on the base 4 and connected to the contact network, an isolating switch 7 hinged to the moving contact 6 for connecting to the stationary contact 5, a transmission mechanism rotatably mounted on the base 4, one end hinged to the drive unit 2 and the other end hinged to the isolating switch 7, a closing detection mechanism on the base 4 for detecting the closed state of the isolating switch 7, a position detection mechanism on the base 4 for detecting the position of the isolating switch 7, and a control mechanism located in the mounting box 3 and connected to the closing detection mechanism and the position detection mechanism respectively.

[0040] The triggering mechanism includes a trigger rod 13 that slides inside the detection box 8, a limiting plate 14 on the trigger rod 13, and a reset spring 15 that is fitted on the outside of the trigger rod 13, with one end abutting against the trigger mounting seat 9 and the other end abutting against the limiting plate 14.

[0041] In this embodiment 3, the trigger rod 13 is slidably disposed inside the detection box 8, and the limiting plate 14 is disposed on the trigger rod 13. The limiting plate 14 can facilitate the limiting of the reset spring 15. In use, when the trigger rod 13 contacts the isolating switch 7, as the isolating switch 7 moves, the isolating switch 7 will push the trigger rod 13 to slide and squeeze the reset spring 15, so that the trigger rod 13 contacts the pressure sensor 10 and opens the pressure sensor 10. The pressure sensor 10 transmits an electrical signal to the microprocessor 22, and the microprocessor 22 controls the closing indicator light 11 to light up, so that the operator can confirm the closing status of the isolating switch 7. Similarly, when the isolating switch 7 is separated from the trigger rod 13, the trigger rod 13 is reset under the push of the reset spring 15, so that the trigger rod 13 is separated from the pressure sensor 10, so that the pressure sensor 10 is closed, and the microprocessor 22 controls the opening indicator light 12 to light up, so that the operator can confirm the status of the isolating switch 7.

[0047] In this embodiment 5, the boss 17 is provided with an external thread, and the guide sleeve 30 is provided with an internal thread. The guide sleeve 30 is threadedly connected to the boss 17. By rotating the guide sleeve 30, the moving distance of the trigger rod 13 can be adjusted, thereby facilitating the trigger rod 13 to open the pressure sensor 10. The mounting groove 18 facilitates the installation of the pressure sensor 10. Example
