Description

Technical Field

[0001] This invention relates to the field of disconnector technology, specifically to an intelligent disconnector. Background Technology

[0002] Disconnecting switches are the most widely used electrical appliances in high-voltage switchgear. Their working principle and structure are relatively simple, but due to their large usage and high reliability requirements, they have a significant impact on the design, construction, and safe operation of substations and power plants. The main function of disconnecting switches is to establish a reliable insulation gap after opening the circuit, separating the equipment or line that needs maintenance from the power supply with a clear disconnection point to ensure the safety of maintenance personnel and equipment.

[0003] Currently, existing disconnect switches can only be closed and opened manually, which is cumbersome and dangerous. Therefore, this invention proposes an intelligent disconnect switch that can solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent disconnect switch to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent disconnect switch, comprising a crossbeam, on which corresponding first and second supporting insulators are provided, a contact seat is provided on the first supporting insulator, a contact is provided on the second supporting insulator, and a contact blade that can contact the contact is hinged on the contact seat;

[0006] The crossbeam is equipped with a self-control mechanism, which includes a rotating rod, an insulating control rod, and a drive source. The rotating rod is rotatably mounted on the crossbeam and located between the first support insulator and the second support insulator. One end of the insulating control rod is hinged to the rotating rod, and the other end is hinged to the insulating control rod. The drive source is driven by the rotating rod, and a controller capable of receiving signals is installed on the drive source.

[0007] As a preferred embodiment of the present invention, the crossbeam is fixedly connected to a downwardly extending column.

[0008] As a preferred technical solution of the present invention, a hand control mechanism is provided on the column. The hand control mechanism includes a support plate connected to the column, a handle rotatably connected to the support plate, a movable rod hinged to the handle, a connecting rod hinged to the movable rod, and the connecting rod connected to the rotating rod.

[0009] As a preferred embodiment of the present invention, the crossbeam is fixedly connected to a housing, the rotating rod passes through the housing, the drive source is fixedly installed inside the housing, and is driven by the rotating rod through a gear set.

[0010] In a preferred embodiment of the present invention, the rotating rod is connected to a closing limit rod and a opening limit rod inside the housing. A closing stop block and an opening stop block are mounted on the inner wall of the housing. The closing stop block matches the closing limit rod, and the opening stop block matches the opening limit rod.

[0011] In a preferred embodiment of the present invention, the contact base is connected to a terminal block, and the contact head is connected to a lead-out plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides an intelligent disconnecting switch. When the intelligent disconnecting switch is closed or opened, the driving source can receive external control signals through the controller to operate. The driving source drives the rotating rod to rotate, and the rotating rod drives the contact blade to move through the insulating control rod, so that the contact blade can contact the contact to achieve the closed state. After the contact blade separates from the contact, the open state is achieved. There is no need for manual operation to close or open the switch. The operation is simple and convenient, with good safety and a high degree of intelligence. Attached Figure Description

[0021] Example 1

[0022] This invention provides a technical solution: an intelligent disconnect switch, comprising a crossbeam 20, on which corresponding first support insulators 21 and second support insulators 22 are arranged. A contact seat 211 is arranged on the first support insulator 21, and a contact 221 is arranged on the second support insulator 22. A contact blade 212, which can contact the contact 221, is hinged to the contact seat 211. A terminal block 213 is connected to the contact seat 211, and a lead-out plate 222 is connected to the contact 221. A self-control mechanism is arranged on the crossbeam 20, comprising a rotating rod 30, an insulating control rod 31, and a drive source 32. The rotating rod 30 is rotatably mounted on the crossbeam 20 and located between the first support insulator 21 and the second support insulator 22. One end of the insulating control rod 31 is hinged to the rotating rod 30, and the other end is hinged to the insulating control rod 31. The drive source 32 is drivenly connected to the rotating rod 30. A controller capable of receiving signals is installed on the drive source 32. The drive source 32 is a servo motor selectable according to its model and has a built-in power supply.

[0023] Specifically, when the intelligent disconnect switch is closed or opened, the drive source 32 can receive external control signals through the controller to operate. The drive source 32 drives the rotating rod 30 to rotate, and the rotating rod 30 drives the contact knife 212 to move through the insulating control rod 31, so that the contact knife 212 can contact the contact 221 to achieve the closed state. After the contact knife 212 separates from the contact 221, it reaches the open state. There is no need for manual operation to close or open the switch. The operation is simple and convenient, with good safety and a high degree of intelligence.

[0024] Example 2

[0025] Based on Embodiment 1, the cross frame 20 is fixedly connected to a downwardly extending column 10; a hand control mechanism is provided on the column 10, the hand control mechanism includes a support plate 40 connected to the column 10, a handle 41 is rotatably connected to the support plate 40, the handle 41 is hinged to a movable rod 42, the movable rod 42 is hinged to a connecting rod 43, and the connecting rod 43 is connected to the rotating rod 30.

[0026] Specifically, by rotating the handle 41, the handle 41 rotates through the movable rod 42 and the connecting rod 43, thereby driving the rotating rod 30 to rotate, realizing the opening and closing of the circuit breaker. This allows the circuit breaker to be opened and closed through a manual control mechanism, and keeps it away from the contact knife 212, ensuring good safety.

[0027] Example 3

[0028] Based on Embodiment 1 or Embodiment 2, the cross frame 20 is fixedly connected to the housing 50, the rotating rod 30 passes through the housing 50, the drive source 32 is fixedly installed inside the housing 50 and is driven by the rotating rod 30 through the gear set 33; the rotating rod 30 is connected to the closing limit rod 301 and the opening limit rod 302 inside the housing 50, the closing stop 501 block and the opening stop 502 block are on the inner wall of the housing 50, the closing stop 501 block matches the closing limit rod 301, and the opening stop 502 matches the opening limit rod 302.

[0029] Specifically, the housing 50 provides protection for the drive source 32, and through the set closing limit rod 301, opening limit rod 302, closing stop block 501 and opening stop block 502, the closing and opening positions of the contact knife 212 are limited to ensure the stability of closing and opening.
