Fig. 1 is a schematic structural diagram of an electrical apparatus and a monitoring apparatus according to an embodiment of the present invention. As shown in fig. 1, the electrical apparatus 1 may include a housing 11 and an electrical component (not shown), the electrical component being disposed in the housing 11 of the electrical apparatus 1, and a viewing window 12 for viewing the electrical component being disposed on the housing 11 of the electrical apparatus 1.

It should be understood that the present embodiment does not limit the operation manner of the image capturing assembly, for example, in an embodiment of the present invention, the image capturing assembly 21 is configured to continuously receive light reflected by an electrical component as a monitoring object in the housing 11 of the electrical apparatus 1 through the observation window 12 in real time and convert the received light into an image signal. For another example, in an embodiment of the present invention, the image capturing assembly 21 is configured to intermittently receive light, which is reflected by an electrical component as a monitoring object in the housing 11 of the electrical device 1, through the observation window 12 for a set period of time, and convert the received light into an image signal.

When the image acquisition component 21 acquires the image signal of the contact position of the isolating/grounding switch through the observation window, the image signal is sent to the display component 22, so that the display component 22 reproduces the image signal and displays the image of the contact position of the isolating/grounding switch. Therefore, according to the image of the contact position of the isolating/grounding switch displayed on the display component, the user can determine the current working state of the isolating/grounding switch, such as the on position, the isolating position or the grounding position, so that the working state of the electrical component in the housing 11 of the electrical device 1 can be known in time, and the use requirement of the user can be better met.
Alternatively, in one embodiment of the present invention, the operating voltage of the high voltage combiner may be between 12 kv and 550 kv.
In this embodiment, the specific implementation manner of the image capturing assembly 21 disposed at the observation window 12 is not limited. Alternatively, referring to fig. 1 and 2, in an embodiment of the present invention, a first flange 121 is disposed on the observation window 12, a hollow region of the first flange 121 is opposite to the observation window 12, the image capturing assembly 21 includes a housing 211 of the image capturing assembly and a lens disposed in the housing 211 of the image capturing assembly, the housing 211 of the image capturing assembly includes a second flange 2111, the second flange 2111 is disposed at an end where the lens is located, and the first flange 121 and the second flange 2111 are connected by a fixing member to fix the image capturing assembly 21 at the observation window 12, so that light reflected by an electric component as a monitoring object in the housing 11 of the electric device 1 passes through the observation window to be received by the lens.
For example, in the present embodiment, an opening may be provided in the housing 11 of the electrical apparatus 1 at a position corresponding to an electrical component to be monitored, and a transparent material (e.g., glass) may be covered on the opening as the observation window 12. Then, the first flange 121 may be mounted in such a manner that the hollow region of the first flange 121 is opposed to the position of the observation window 12, thereby disposing the first flange 121 on the observation window 12. In order to dispose the image pickup assembly 21 of the monitoring apparatus 2 at the observation window 12, as shown in fig. 2, the housing 211 of the image pickup assembly includes a second flange 2111. The second flange 2111 is disposed at an end where the lens is located, for example, sleeved on the lens barrel portion 2112 in the housing 211 of the image capturing assembly or integrally formed with the lens barrel portion 2112, where the lens barrel portion 2112 is a section for accommodating the lens in the housing 211 of the image capturing assembly. When it is necessary to mount the image pickup assembly 21 to the observation window 12, the first flange 121 and the second flange 2111 may be fixed by a fixing member (e.g., a bolt, a screw, or the like), so that the image pickup assembly 21 may be disposed at the observation window 12 in a simple mounting manner.
In addition, when the image pickup unit 21 is fixed to the observation window 12 in the above manner, the lens of the image pickup unit 21 may extend through the hollow region of the first flange 121 to be attached to the observation window 12, whereby the image signal of the electric component as the monitoring target located in the housing 11 of the electric device 1 may be more clearly picked up.
For better fit with the hollow region of first flange 121, optionally, in one embodiment of the utility model, barrel portion 2112 for receiving the lens of image capture assembly 21 is cylindrical. Also, optionally, in one embodiment of the utility model, the diameter of the barrel portion 2112 is less than or equal to 25 mm.
It should be understood that barrel portion 2112 of image acquisition assembly 21 may take other shapes, such as a square shape. The size of the barrel portion 2112 may be set as needed, and this embodiment is not limited thereto.
In the embodiment of the present invention, in order to protect the electrical components included in the electrical apparatus 1, the electrical components included in the electrical apparatus 1 are enclosed in a casing provided with a viewing window 12. Therefore, the light in the housing 11 of the electrical apparatus 1 is poor, and a light supplement lamp may be provided in the image capturing assembly 21 in order to capture a clear image of an electrical component located in the housing 11 of the electrical apparatus 1.
For example, in one embodiment of the present invention, as shown in fig. 2 and 3, the image capturing assembly 21 includes a fill-in light 212, and a photo-electric sensing unit (not shown). The fill light 212 is disposed in the housing 211 of the image capturing assembly 21. A light-passing hole 2113 is formed in the position of the housing 211 of the image capturing assembly corresponding to the light supplement lamp 212, so that light emitted by the light supplement lamp 212 passes through the light-passing hole 2113 and the observation window 12 and enters the housing of the electrical apparatus. The lens receives light emitted from the fill light 212, which is incident on and reflected by an electrical component, which is a monitoring object, in the housing 211 of the electrical device through the light passing hole 2113 and the observation window 12, and focuses the light reflected by the electrical component on the photoelectric sensing unit, so that the photoelectric sensing unit converts the light focused by the lens into an image signal. In this embodiment, since the light emitted from the light supplement lamp can pass through the light passing hole 2113 and the observation window 12 and enter the housing of the electrical apparatus to provide illumination, the image acquisition assembly 21 can acquire a clear image of the electrical apparatus assembly.
Specifically, as shown in fig. 3, three light passing holes 2113 are provided in the housing 211 of the image pickup assembly at positions corresponding to the fill-in lamps 212, and the three light passing holes 2113 are collectively provided on one side of the distal end surface of the lens barrel portion of the housing 211 of the image pickup assembly, so that light emitted from the fill-in lamps 212 is emitted through the three light passing holes 2113. It should be understood that the three light passing holes 2113 shown in fig. 3 are only for illustration, and more than three or less than three light passing holes 2113 may be provided on the housing 211 of the image capturing assembly according to actual needs, which is not limited in this embodiment.
In order to ensure normal and stable operation of the fill-in lamp, optionally, in an embodiment of the present invention, as shown in fig. 4, the fill-in lamp may include a plurality of infrared LED lamps, which are connected in parallel and arranged around the lens of the image capturing assembly 21. A plurality of infrared LED lamps 212 arranged around the lens of the image capturing assembly 21 are connected in parallel, and normal and stable operation of the light supplement lamp can be ensured by selecting and reasonably combining the power supplies of the plurality of infrared LED lamps.
It should be understood that a plurality of infrared LED lamps may be connected in series and/or otherwise disposed with respect to the lens of the image capturing assembly 21, and the present embodiment is not limited thereto.
It should be noted that, because the housing 211 of the image capturing assembly further accommodates electronic components such as an image sensor that are responsible for converting image signals into electrical signals, the housing 211 of the image capturing assembly is made of a metal material, which can shield electromagnetic interference generated by the electronic components.
In addition, the second flange 2111 is made of a metal material, and when the image capturing assembly 21 is disposed at the observation window 12, a portion of the housing 211 of the image capturing assembly, which has the light passing hole 2113, is accommodated in the cavity defined by the first flange 121 and the second flange 2111, so that the cooperation of the first flange 121 and the second flange 2111 can shield Electromagnetic interference brought by the image capturing assembly 21 through the light passing hole 2113, and ensure that the image capturing assembly 21 meets an Electromagnetic Compatibility (EMC) standard.
Further, in the present embodiment, for convenience of explanation, only one observation window 12 is shown in fig. 1, and it is to be understood that, in practical applications, the electric appliance 1 may include two or more electric components as monitoring objects, and accordingly, the observation windows 12 may be respectively provided on the housing 11 at positions corresponding to these electric components as monitoring objects. For example, an isolating/grounding switch, a circuit breaker, a transformer, etc. may be included in the electrical apparatus 1, and a user needs to monitor the operating states of the isolating/grounding switch and the circuit breaker in the electrical apparatus 1, and therefore, viewing windows 12 may be respectively provided on the housing 11 of the electrical apparatus 1 at positions corresponding to the isolating/grounding switch and the circuit breaker, and accordingly, image capturing assemblies 21 may be provided at these viewing windows 12, so that the operating states of the isolating/grounding switch and the circuit breaker may be monitored by the image capturing assemblies 21 provided at these viewing windows 12.
In order to be able to switch and display images of an electrical component as a monitoring object located in a housing of the electrical apparatus 1, which images are captured by an image capturing component provided at each observation window 12, using the display component 22, to reduce the cost and the occupied space of the monitoring panel. Optionally, in an embodiment of the present invention, the housing 11 of the electrical apparatus 1 comprises a plurality of observation windows 12, the monitoring apparatus 2 comprises a plurality of image capturing assemblies 21, and one of the plurality of image capturing assemblies 21 is disposed at each observation window 12;

Specifically, the connection relationship of the image capturing unit 21, the selection switch 231, and the display unit 22 is as shown in fig. 5. In fig. 5, the selection switch 231 is disposed between the display module 22 and the image capturing module 21. In addition, a power supply 24 for supplying power to the image acquisition assembly 21, the display assembly 22 and the control assembly 23, and a PCB board 25 for taking charge of power supply control and signal transmission are also shown in fig. 5. The image acquisition assembly 21 can not acquire the image signal of the electric appliance assembly as the monitoring object positioned in the shell 11 of the electric appliance device 1 by disconnecting the power supply 24 from the electric connection with the image acquisition assembly 21. Further, it should be understood that the PCB board 25 and the power supply 24 may be arranged according to actual needs. The PCB board 25 is disposed between the selection switch 231 and the image pickup assembly 21. When the image acquisition assembly 21 acquires the image signal of the electrical component located in the electrical apparatus, the image acquisition assembly 21 transmits the image signal to the PCB 25 via the cable, and the image signal is displayed on the display assembly 22 via the selection switch 231 after being converted by the PCB 25.
In order to enable more image capturing assemblies 21 to share the display assembly 22, a plurality of selection switches 231 may be provided according to the actual field requirements of the product, in addition to considering the number of selection items (i.e., the number of second terminals) each selection switch 231 has.
Alternatively, in an embodiment of the present invention, the control component 23 includes a plurality of selection switches, the plurality of selection switches are connected in series to form a plurality of switch combination states, the plurality of switch combination states correspond to the plurality of image capturing components one to one, and when the plurality of selection switches are in one of the plurality of switch combination states, the image capturing component corresponding to the switch combination state among the plurality of image capturing components is connected to the display component 22.
For the sake of understanding, the operation principle of the plurality of selector switches will be described in detail with reference to fig. 4 and 5 by way of an example.
As shown in fig. 4, the monitoring apparatus 1 includes a display unit 22 and two selection switches 231 serving as control units. Hereinafter, for convenience of description, the selection switch positioned on the left side in fig. 4 is referred to as a first selection switch 231A, and the selection switch positioned on the right side in fig. 4 is referred to as a second selection switch 231B. In the present example, the first selection switch 231A has three options, which are a-phase, B-phase, and C-phase, respectively. The first selection switch 231A is used to select which of the three phases in the housing of the electrical apparatus is associated with the electrical component to monitor. The second selection switch 231B has two options, namely a disconnecting switch DS and a grounding switch ES. A second selection switch 223 is used to select whether the earthing switch or the isolating switch associated with the selected phase line is to be monitored.

For example, when the first selection switch 231A is placed in the C phase and the second selection switch 231B is placed in the DS, the image capturing component for capturing the image signal of the isolation switch associated with the C phase converts the captured image signal via the PCB and transmits the converted image signal to the display component 22, and the display component 22 displays the image of the isolation switch associated with the C phase, specifically, displays the operating state of the isolation switch. For another example, when the first selection switch is placed in the a phase and the second selection switch is placed in the ES phase, the image capturing component for the image signal of the grounding switch associated with the a phase converts the captured image signal via the PCB and transmits the converted image signal to the display component 22, and the display component 22 displays the operating state of the grounding switch associated with the C phase.
