Description

Technical Field

[0001] The utility model relates to the field of power supply devices, in particular to the field of grounding anti-interference capability verification, and specifically refers to a test device that supports the implementation of grounding anti-interference capability verification for a PSE switch. Background Art

[0002] With the advancement of network technology, remote power supply (PSE) switches are increasingly being used to power PDs, such as cameras and wireless access points. Due to the varying grounding conditions of different devices, the power supply system comprised of the PSE switch is often subject to significant interference from the ground line. This interference is often introduced into the network cable, interfering with the switch's power supply protocol and frequently affecting the powered PDs. The reliability of these devices is crucial. Imagine the significant impact of a surveillance camera suddenly failing or a wireless access point being unable to power on. Therefore, verifying the grounding and interference resistance of the PSE switch is essential. However, traditional verification schemes often suffer from issues such as: 1) the inability to traverse the grounding conditions between the switch and the powered device; 2) the inability to easily introduce interference from static ground lines. These issues can lead to deviations in verification, and in actual testing, they may not fully meet test requirements.

[0003] Currently, verification focuses primarily on grounding of power supply equipment (PSEs), while grounding of powered devices (PDs) is often neglected. Even when grounded, verification of shared grounding with the PSEs is often inadequate. Furthermore, various grounding combinations for PSEs and PDs have not been fully verified. Live network conditions are often diverse, and reliability must be fully guaranteed. Utility Model Content

[0006] This test device supports verification of the grounding anti-interference capability of a PSE switch.
