Description

Technical Field

[0001] This utility model belongs to the field of disconnecting switch technology, and specifically relates to a visual contact wire disconnecting switch. Background Technology

[0002] A disconnecting switch is a switching device primarily used for isolating power supplies, switching operations, and connecting and disconnecting small-current circuits, without arc-extinguishing functionality. When in the open position, the disconnecting switch has a specified insulation distance between its contacts and a clear disconnection mark; when in the neutral position, it can carry current under normal circuit conditions as well as current under abnormal conditions (such as short circuits) for a specified time.

[0003] Disconnect switches are devices located on poles or towers. When operators are operating them on the ground or on the pole, there are blind spots, making it difficult to visually observe the status of the equipment and confirm whether the disconnect switch is fully closed or open. If the disconnect switch is not fully closed or open, and the overhead contact line is energized, the equipment may overheat, the disconnect switch may break down, and this could lead to overhead contact line tripping and other situations that endanger the safe operation of the line.

[0029] 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.

[0030] 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.

[0031] 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

[0032] like Figure 1-10 As shown, the present invention provides a visual contact network disconnector, comprising a mounting frame 1, a plurality of first insulating posts 2 and second insulating posts 3 disposed on the mounting frame 1, a mounting plate 4 disposed on the first insulating posts 2, a stationary contact 5 disposed on the mounting plate 4, a moving contact 6 disposed on the second insulating posts 3, and an isolation blade 7 hinged to the moving contact 6, and a transmission mechanism disposed on the mounting frame 1 and hinged to the isolation blade 7; the mounting plate 4 is provided with a detection mechanism for detecting the closed and open states of the isolation blade 7, and a pressure detection mechanism for detecting the loose state of the isolation blade 7; and a control mechanism connected to the detection mechanism and the pressure detection mechanism is provided outside the mounting plate 4.

[0033] In this utility model, the transmission mechanism is connected to the drive mechanism. The detection mechanism can detect the closed or open state of the disconnecting switch and provide feedback on the detection results through the closed indicator light 26 or the open indicator light 27. This allows the operator to determine the closed or open state of the disconnecting switch based on the closed indicator light 26 or the open indicator light 27, thus facilitating the operation of the disconnecting switch. At the same time, the pressure detection mechanism can detect the closing pressure of the disconnecting blade 7, thereby preventing the disconnecting blade 7 from failing to close properly.

[0034] In use, the microcontroller 25 controls the infrared transmitter 9 to continuously emit light signals. When the circuit is closed, the drive mechanism drives the transmission shaft 21 to rotate, the transmission shaft 21 drives the rotating plate 22 to rotate, the rotating plate 22 drives the third insulating post 23 to move, and the third insulating post 23 pushes the isolation blade 7 to rotate. When the isolation blade 7 contacts the stationary contact 5, the isolation blade 7 is located between the infrared transmitter 9 and the infrared receiver 10, and the isolation blade 7 blocks the light signal emitted by the infrared transmitter 9. At this time, the infrared receiver 10 cannot receive the light signal emitted by the infrared transmitter 9, and the microcontroller 25 controls the closing indicator light 26 to stay on. The operator can understand the closing status of the isolation blade 7 through the closing indicator light 26 and the value displayed on the display screen 28. Similarly, when the circuit is opened, the infrared receiver 10 can receive the light signal emitted by the infrared transmitter 9 again and transmit the signal to the microcontroller 25. At this time, the microcontroller 25 controls the opening indicator light 27 to stay on according to the received light signal. This process can realize the visual operation of opening or closing the disconnecting switch.

[0035] When the isolating blade 7 contacts the insulating seat 13, the isolating blade 7 pushes the insulating seat 13 downward, and the insulating seat 13 drives the trigger insulating rod 15 downward, while simultaneously squeezing the support spring 17, causing the trigger insulating rod 15 to squeeze the pressure sensor 14. The pressure sensor 14 detects the pressure of the trigger insulating rod 15 and transmits the detection result to the microcontroller 25. The microcontroller 25 transmits the detection result of the pressure sensor 14 to the display screen 28. The operator can determine whether the isolating blade 7 and the stationary contact 5 are properly closed based on the pressure value displayed on the display screen 28.

[0036] The infrared transmitter 9 of this utility model is an infrared transmitter, and the infrared receiver 10 is an infrared receiver. Example

[0037] like Figure 1-10 As shown, the present invention provides a visual contact network disconnector, comprising a mounting frame 1, a plurality of first insulating posts 2 and second insulating posts 3 disposed on the mounting frame 1, a mounting plate 4 disposed on the first insulating posts 2, a stationary contact 5 disposed on the mounting plate 4, a moving contact 6 disposed on the second insulating posts 3, and an isolation blade 7 hinged to the moving contact 6, and a transmission mechanism disposed on the mounting frame 1 and hinged to the isolation blade 7; the mounting plate 4 is provided with a detection mechanism for detecting the closed and open states of the isolation blade 7, and a pressure detection mechanism for detecting the loose state of the isolation blade 7; and a control mechanism connected to the detection mechanism and the pressure detection mechanism is provided outside the mounting plate 4.

[0038] The testing mechanism includes infrared mounting boxes 8 located on both sides of the mounting plate 4, an infrared transmitter 9 located on one of the infrared mounting boxes 8, and an infrared receiver 10 located on the other infrared mounting box 8 and adapted to the infrared transmitter 9.

[0039] In this embodiment 2, infrared mounting boxes 8 are arranged on both sides of the mounting plate 4, and infrared transmitter 9 is installed in one of the infrared mounting boxes 8, while infrared receiver 10 is installed in the other infrared mounting box 8. The infrared mounting boxes 8 can easily protect the infrared transmitter 9 and the infrared receiver 10.

[0040] In use, when the isolating blade 7 is in the closed state, it blocks the light signal emitted by the infrared transmitter 9. At this time, the infrared receiver 10 cannot receive the light signal emitted by the infrared transmitter 9. Simultaneously, the infrared receiver 10 transmits the result to the microcontroller 25. The microcontroller 25 then controls the closed indicator light 26 to stay on, thereby reminding the operator that the isolating blade 7 is in the closed state. Similarly, when the circuit is opened, the infrared receiver 10 receives the light signal emitted by the infrared transmitter 9 again and transmits the result to the microcontroller 25. The microcontroller 25 controls the open indicator light 27 to stay on, thereby reminding the operator that the isolating blade 7 is in the open state. Example

[0041] like Figure 1-10 As shown, the present invention provides a visual contact network disconnector, comprising a mounting frame 1, a plurality of first insulating posts 2 and second insulating posts 3 disposed on the mounting frame 1, a mounting plate 4 disposed on the first insulating posts 2, a stationary contact 5 disposed on the mounting plate 4, a moving contact 6 disposed on the second insulating posts 3, and an isolation blade 7 hinged to the moving contact 6, and a transmission mechanism disposed on the mounting frame 1 and hinged to the isolation blade 7; the mounting plate 4 is provided with a detection mechanism for detecting the closed and open states of the isolation blade 7, and a pressure detection mechanism for detecting the loose state of the isolation blade 7; and a control mechanism connected to the detection mechanism and the pressure detection mechanism is provided outside the mounting plate 4.

[0042] The detection mechanism includes infrared mounting boxes 8 respectively located on both sides of the mounting plate 4, an infrared transmitter 9 located in one of the infrared mounting boxes 8, and an infrared receiver 10 located in the other infrared mounting box 8 and adapted to the infrared transmitter 9; the control mechanism is connected to the infrared transmitter 9 and the infrared receiver 10 respectively.

[0043] The infrared mounting box 8 has a transparent glass 11 on one side.

[0044] In this embodiment 3, the transparent glass 11 can easily protect the infrared transmitter 9 and the infrared receiver 10, while not hindering the infrared receiver 10 from receiving the light signal emitted by the infrared transmitter 9. Example

[0045] like Figure 1-10 As shown, the present invention provides a visual contact network disconnector, comprising a mounting frame 1, a plurality of first insulating posts 2 and second insulating posts 3 disposed on the mounting frame 1, a mounting plate 4 disposed on the first insulating posts 2, a stationary contact 5 disposed on the mounting plate 4, a moving contact 6 disposed on the second insulating posts 3, and an isolation blade 7 hinged to the moving contact 6, and a transmission mechanism disposed on the mounting frame 1 and hinged to the isolation blade 7; the mounting plate 4 is provided with a detection mechanism for detecting the closed and open states of the isolation blade 7, and a pressure detection mechanism for detecting the loose state of the isolation blade 7; and a control mechanism connected to the detection mechanism and the pressure detection mechanism is provided outside the mounting plate 4.

[0046] The pressure detection mechanism includes a pressure mounting base 12 disposed on the mounting plate 4, an insulating base 13 slidably disposed on the pressure mounting base 12, a limiting guide mechanism disposed between the pressure mounting base 12 and the insulating base 13, a pressure sensor 14 disposed on the pressure mounting base 12 and connected to the control mechanism, and a trigger insulating rod 15 slidably disposed through the pressure mounting base 12 and connected to the insulating base 13 for triggering the pressure sensor 14.

[0047] In this embodiment 4, the pressure mounting seat 12 is fixed on the mounting plate 4, the insulating seat 13 is slidably mounted on the pressure mounting seat 12, the limiting guide mechanism can guide the sliding direction of the insulating seat 13 and limit the sliding position of the insulating seat 13, and the pressure sensor 14 is mounted on the pressure mounting seat 12 and is in contact with the trigger insulating rod 15.

[0048] In use, when the isolating blade 7 is in the closed state, the isolating blade 7 drives the insulating seat 13 to move downward. During the movement, the insulating seat 13 compresses the supporting spring 17. At the same time, the insulating seat 13 drives the trigger insulating rod 15 to move downward, and the trigger insulating rod 15 compresses the pressure sensor 14. This allows the pressure sensor 14 to detect the closing force of the isolating blade 7. The pressure sensor 14 transmits the detection result to the microcontroller 25, and the microcontroller 25 displays the detection result of the pressure sensor 14 on the external display screen 28. This makes it easier for the operator to determine the closing force of the isolating blade 7, thereby reducing the probability of the isolating blade 7 becoming loose after closing. Example

[0052] In this embodiment 5, the insulating guide rod 16 slides through the insulating seat 13 and is threadedly connected to the pressure mounting seat 12. The support spring 17 is fitted on the outside of the insulating guide rod 16 and is located between the pressure mounting seat 12 and the insulating seat 13. The support spring 17 can support the insulating seat 13, and the insulating guide rod 16 can also limit the sliding direction of the insulating seat 13. Example

When in use, the drive mechanism drives the drive shaft 21 to rotate, and the drive shaft 21 drives the rotating plate 22 to rotate.

Example
