[0033] Please refer to Figures 1 to 2 One embodiment discloses a remote protection closing device for high-voltage switchgear power supply, including a cabinet 1, the cabinet 1 having a first cavity; and a switch assembly 2 arranged inside the first cavity and connected to the power supply circuit.
[0034] The monitoring component 3 is arranged inside the first cavity and above the gate component 2. The monitoring component 3 includes a drive unit 31, a moving unit 32 connected to the drive unit 31, and a monitoring platform 33 connected to the moving unit 32. The drive unit 31 includes a first moving trajectory and is arranged to drive the moving unit 32 to move along the first moving trajectory. The monitoring platform 33 includes at least an image transmission component 332, which is arranged toward the gate component 2.
[0035] In the above embodiment, a first cavity is arranged inside the cabinet 1, providing an installation environment for the internal components and also serving a protective and isolation function. The gate assembly 2 is installed inside the first cavity of the cabinet 1 and is directly connected to the power supply circuit. According to the operation command, it realizes the closing and opening operations of the circuit, thereby controlling the current flow. The embodiment also includes a monitoring assembly 3, which is installed inside the first cavity and located above the gate assembly 2. The monitoring assembly 3 can comprehensively and clearly observe the status of the gate assembly 2. The monitoring assembly 3 consists of three main parts: a drive unit 31, a moving unit 32, and a monitoring platform 33. The drive unit 31 is the power source of the monitoring assembly 3. It has a predetermined first moving trajectory and can drive the moving unit 32 to move precisely along this trajectory. For some larger cabinets 1, the monitoring area of a single monitoring platform may not be able to cover the entire cabinet. However, the monitoring platform 33 in this embodiment can monitor different areas of the gate assembly 2 as needed, thereby obtaining more comprehensive and accurate status information. The monitoring platform 33 includes at least one image transmission component 332. The monitoring area of the image transmission component 332 includes the area where the gate assembly 2 is located. It can capture and transmit the status images of the gate assembly 2 in real time. In one embodiment, the image transmission component 332 uses a high-resolution camera. The staff of the remote monitoring center can understand the working status of the gate assembly 2 in real time through the received images, so as to confirm the status of the gate assembly without going to the site directly. In one embodiment, the monitoring platform 33 is also equipped with other sensors and detection devices, such as temperature sensors and humidity sensors, in order to more comprehensively monitor the environmental status inside the high-voltage cabinet.
[0036] In one embodiment, the cabinet 1 includes a cabinet component 11 with a first opening on its side wall. A plate component 12 is movably connected to the first opening of the cabinet component 11. In a first state, the plate component 12 blocks the first opening; in a second state, the plate component 12 does not block the first opening. In the first state, the plate component 12 blocks the first opening to prevent external dust, moisture, or other contaminants from entering the cabinet, thereby protecting the internal electronic components and circuits from damage and preventing unauthorized personnel from accessing the internal circuits or components. In the second state, the plate component 12 no longer blocks the first opening. By opening the opening, technicians can easily access the interior of the cabinet to perform necessary operations.
[0037] In one embodiment, the switch assembly 2 is configured as a vacuum circuit breaker. The vacuum circuit breaker includes a disconnecting switch, a drive shaft, and an isolating stationary contact. One or more disconnecting switches are fitted onto the surface of the drive shaft. One end of the disconnecting switch is driven to contact or separate from the isolating stationary contact located on the internal frame of the cabinet 1. The disconnecting switch is fitted onto the surface of the drive shaft. This switch can move with the rotation of the drive shaft, thereby achieving contact or separation with the isolating stationary contact. The disconnecting switch is made of a metal material with good conductivity. The drive bearing is subjected to force from the operating mechanism or drive device and transmits these forces to the disconnecting switch. The isolating stationary contact is a stationary component corresponding to the disconnecting switch. It is fixed on the internal frame of the cabinet 1, awaiting the action of the disconnecting switch. When the disconnecting switch moves to the position of contacting the isolating stationary contact under the drive of the drive shaft, the circuit is connected; when the switch separates from the stationary contact, the circuit is disconnected.
[0038] Please refer to Figure 3 In one embodiment, the drive unit 31 includes a rack member 311 arranged along a first moving trajectory; and a gear member 312, with the rack member 311 and gear member 312 arranged correspondingly. The gear member 312 is sleeved on the shaft of a first motor, and the end of the first motor is fixedly connected to the moving part 32. Specifically, the gear member 312 is sleeved on the shaft of the first motor. When the first motor starts, its shaft drives the gear member 312 to rotate. Due to the meshing relationship between the gear member 312 and the rack member 311, this rotational motion is converted into linear motion of the rack member 311, thereby driving the moving part 32 to move along the first moving trajectory.
[0039] Please refer to Figure 4 and Figure 5 In one embodiment, a second opening is arranged on the top of the cabinet 1, and a second plate component 4 is arranged at the position of the second opening. The second plate component 4 includes a metal region 41 and a light-transmitting region 42 embedded in the metal region 41. The light-transmitting region 42 is configured as a light guide plate, with a light-inlet end and a light-outlet end facing away from the first cavity. The monitoring platform 33 also includes a support substrate 331, which is connected to the moving part 32. An image transmission component 332 is fixedly arranged on one side surface of the support substrate 331. A light source component 33... 3. The light source component 333 is arranged on one side surface of the support substrate 331, and its light emission direction faces the light-inlet end. In specific implementation, the light source component 333 is placed on one side surface of the support substrate 331, and its light emission direction is deliberately directed towards the light-inlet end of the light guide plate. This ensures that the light emitted by the light source component can directly and efficiently enter the light guide plate and be guided out from the light-emission end by the light guide plate. When the gate component malfunctions, the moving part 32 moves the light source component 333 to the light-inlet end and illuminates the light source component. At this time, the light guide plate will emit light, providing a clear warning to the personnel on site.
[0040] In summary, this utility model discloses a remote protection closing device for high-voltage switchgear, comprising a cabinet, a switch assembly, and a monitoring component. The cabinet has an internal cavity for installing and protecting the internal components. The switch assembly is installed in the first cavity and directly connected to the power transmission circuit, responsible for closing and opening operations according to instructions, thereby controlling the current flow. The monitoring component is located above the switch assembly, used for comprehensive and clear observation of the switch assembly's status. The monitoring component consists of a drive unit, a moving unit, and a monitoring platform. The drive unit can drive the moving unit to move precisely along a predetermined trajectory, allowing the monitoring platform to cover different areas for monitoring. The monitoring platform is equipped with at least one image transmission component, such as a high-resolution camera, capable of capturing and transmitting real-time images of the switch assembly's status, enabling personnel at the remote monitoring center to understand the switch assembly's operating status in real time without needing to be physically present. Furthermore, the monitoring platform can also be equipped with other sensors and detection devices to more comprehensively monitor the environmental conditions inside the high-voltage switchgear.
