Description

Technical Field

[0001] The utility model relates to but is not limited to the technical field of power equipment detection, and in particular to a circuit breaker moving and static contact monitoring device and a switch cabinet thereof. Background Art

[0002] As today's society is highly dependent on electric energy, higher and higher requirements are also put forward for the reliability of power supply equipment. As a removable metal-enclosed switchgear with comprehensive technical advantages, it is currently widely used in various power-using occasions. Since the high-voltage circuit breaker and the switch cabinet are connected by moving and static contacts, the contacts are often worn due to the high-temperature arc burning and violent collision during the repeated switching actions of the circuit breaker. When the wear exceeds the limit value specified by the circuit breaker (generally less than 3mm), the closing will not work properly, causing power grid accidents. Therefore, it is necessary to monitor the connection between the moving and static contacts in the switch cabinet. The existing monitoring method mainly selects traditional indirect temperature measurement points on the copper busbar connected to the moving and static contacts, and adds paraffin or temperature sensing sheets to the indirect temperature measurement points. The manual patrol is carried out regularly, and the temperature is roughly judged according to the melting degree of paraffin or the color change of temperature by the principle of heat conduction. The temperature is indirectly inferred from the connection temperature of the moving and static contacts, and manual intervention is implemented. The temperature measured in this way is not the directly measured temperature of the moving and static contacts, and the accuracy is low, and a certain labor cost is required. Utility Model Content

[0033] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings.

[0034] refer to Figure 1 , the embodiment of the present application provides a circuit breaker moving and static contact monitoring device, comprising:

[0035] A periscope light guide is inserted into the switch cabinet 200, a light inlet of the periscope light guide protrudes from the side wall of the switch cabinet 200, a light outlet of the periscope light guide is close to the moving and static contacts 210 of the circuit breaker, and a reflector is provided at the bend of the periscope light guide;

[0036] A light-emitting component, which is arranged on the inner wall near the light entrance of the periscope light guide tube;

[0037] A camera assembly, the camera assembly is close to the light entrance of the periscope light guide;

[0040] The control processing module is respectively connected to the light emitting component, the communication module, the camera component and the temperature detection component for communication.

[0041] It can be understood that the circuit breaker moving and static contact monitoring device of the embodiment of the present application includes a periscope light guide, which is inserted into the switch cabinet 200, the light inlet of the periscope light guide protrudes from the side wall of the switch cabinet 200, the light outlet of the periscope light guide is close to the circuit breaker moving and static contacts 210, and a reflector is provided at the bend of the periscope light guide; a light emitting component, which is arranged on the inner wall close to the light inlet of the periscope light guide; a camera component, which is close to the light inlet of the periscope light guide; a temperature detection component, which is used to detect the temperature value of the contact port of the moving and static contacts of the circuit breaker; a communication module, which is communicatively connected to the cloud platform server; and a control processing module, which is communicatively connected to the light emitting component, the communication module, the camera component and the temperature detection component respectively. When the light-emitting component is powered on and in the lit state, the light emitted by the light-emitting component is conducted along the pipe of the periscope light guide tube and through the reflectors at each bend, and then emitted from the light outlet of the periscope light guide tube. Since the light outlet is close to the moving and static contacts 210 of the circuit breaker, Figure 1 The light outlet shown is close to the contact end between the moving and static contacts 210 of the circuit breaker and the copper busbar interface 221 of the copper busbar 220, thereby illuminating the contact end, and combining with the camera component to obtain the image of the contact end between the moving and static contacts 210 of the circuit breaker and the copper busbar interface 221, and combining with the temperature detection component to obtain the temperature value of the contact end, the obtained image and temperature value are transmitted to the cloud platform server through the communication module for monitoring personnel to view, so that the status of the moving and static contacts 210 of the circuit breaker can be effectively monitored, and the wear condition of the contact end of the moving and static contacts 210 of the circuit breaker can be effectively determined, thereby ensuring the equipment safety of the switch cabinet 200.

[0042] It should be noted that the embodiments of the present application do not limit the specific structure of the temperature detection component, which can be a wireless temperature measurement component or an infrared temperature measurement component, and those skilled in the art can select it according to actual needs.

[0043] It should be noted that the embodiments of the present application do not limit the specific structure of the light guide tube, which may be integrally formed or may be obtained by splicing multiple tubes together, and those skilled in the art may determine this based on actual conditions.

[0044] It should be noted that the embodiments of the present application do not limit the specific number of bends and reflectors of the periscope light guide. Figure 1 The specific number of reflectors in the periscope light guide is determined by the specific number of bends in the periscope light guide, and can be determined by those skilled in the art according to actual needs. For example, in the embodiment of the present application, the periscope light guide has three bends, and three reflectors are correspondingly arranged.

[0045] It should be noted that the embodiment of the present application does not limit the specific structure of the communication module, which can be a WIFI module or a Bluetooth module as long as it can communicate with the cloud platform server and transmit data.

[0046] In addition, the embodiments of the present application do not limit the specific structure of the camera assembly, nor do they limit the specific number of periscope light guides and light-emitting assemblies. Figure 2 As shown, the periscope light pipe at least includes a first light pipe 110 and a second light pipe 120, the light emitting assembly includes a first light emitting assembly 111 and a second light emitting assembly 121, the reflector includes at least a first reflector 112 and a second reflector 122, the camera assembly includes a first camera 131 and a second camera 132, the first light emitting assembly 111 is arranged on the inner wall of the first light entrance 115 close to the first light pipe 110, the second light emitting assembly 121 is arranged on the inner wall of the second light entrance 125 close to the second light pipe 120, the first reflector 112 is arranged at the bend of the first light pipe 110, the second reflector 122 is arranged at the bend of the second light pipe 120, the first camera 131 assembly is close to the first light entrance 115, and the second camera 132 assembly is close to the second light entrance 125. It can be understood that, with reference to Figure 2 The first light outlet 116 is close to one side of the circuit breaker moving and static contacts 210, and the second light outlet 126 is close to the other side of the circuit breaker moving and static contacts 210. The first camera 131 and the second camera 132 can obtain images of the contact ends between the circuit breaker moving and static contacts 210 and the copper busbar interface 221 of the copper busbar 220 at multiple angles, which can provide an effective data basis for determining the wear condition of the contact ends of the circuit breaker moving and static contacts 210. It can also be as follows Figure 1 As shown, the camera assembly only includes a third camera 131, and the camera assembly is close to the first light entrance 115 and the second light entrance 125. Based on this structure, the circuit breaker moving and static contact monitoring device of the embodiment of the present application may also include a driving device, which is communicated with the camera assembly and the control processing module respectively, and the driving device is used to drive the lens of the camera assembly to periodically stay at the first light entrance 115 or the second light entrance 125 and take images, thereby reducing the cost of the camera assembly and thus reducing the cost of the circuit breaker moving and static contact monitoring device.

[0047] In some embodiments, reference Figure 1 and Figure 2 The circuit breaker moving and static contact monitoring device also includes: a condenser lens, which is arranged on the inner wall of the periscope light guide tube close to the light-emitting component.

[0048] It is understandable that the specific number of the focusing lenses in the embodiment of the present application is determined by the specific number of the periscope light guide tubes. Figure 1 and Figure 2The first light guide tube is provided with a first condensing lens 113 on the inner wall close to the first light emitting component, and the second light guide tube is provided with a second condensing lens 123 on the inner wall close to the second light emitting component. Based on the structure that the condensing lens is provided on the inner wall of the periscope light guide tube close to the light emitting component, when the light emitting component is in the light emitting state, the light emitted by the light emitting component can be concentrated and the brightness can be enhanced, thereby achieving the effect of increasing the light output intensity of the periscope light guide tube.

[0049] In some embodiments, reference Figure 1 and Figure 2 The circuit breaker moving and static contact monitoring device also includes: a divergent lens, which is arranged on the inner wall of the periscope light guide tube close to the light outlet.

[0050] It is understandable that the specific number of divergent lenses in the embodiment of the present application is determined by the specific number of periscope light guides. Figure 1 and Figure 2 The inner wall of the first light guide tube near the first light outlet is provided with a first diverging lens 114, and the inner wall of the second light guide tube near the second light outlet is provided with a second diverging lens 124. Based on the structure that the inner wall of the periscope light guide tube near the light outlet is provided with a diverging lens, the light transmitted to the light outlet can be diverged, so as to better illuminate the contact end between the moving and static contacts 210 of the circuit breaker and the copper busbar interface 221 of the copper busbar 220.

[0051] In addition, in some embodiments, the circuit breaker moving and static contact monitoring device further includes: an alarm module, and the alarm module is communicatively connected with the camera assembly, the communication module and the communication module respectively.

[0052] It can be understood that the embodiments of the present application do not limit the specific structure of the alarm module, which can be a sound alarm module. When the control processing module determines that the image acquired by the camera does not meet the preset conditions (that is, it indicates that the contact end between the moving and static contacts 210 of the circuit breaker and the copper busbar interface 221 of the copper busbar 220 is severely damaged), an alarm signal is generated according to the image, and the alarm signal is sent to the cloud platform server through the communication module, and a sound alarm is triggered.

[0053] In addition, an embodiment of the present application further provides a switch cabinet 200, which includes the circuit breaker moving and static contact monitoring device described in any one of the above embodiments.

[0054] It can be understood that since the switch cabinet 200 of this embodiment is provided with the circuit breaker moving and static contact monitoring device of the first aspect embodiment, the contact ends between the circuit breaker moving and static contacts 210 and the copper busbar 220 inside the switch cabinet 200 can be illuminated by the periscope light guide in the circuit breaker moving and static contact monitoring device, and the image of the contact ends between the circuit breaker moving and static contacts 210 and the copper busbar 220 can be obtained in combination with the camera component, so that the circuit breaker moving and static contacts 210 can be effectively monitored by image, thereby ensuring the equipment safety of the switch cabinet 200.
