[0022] This utility model provides a novel cylindrical antenna with a sealed flange for monitoring the internal temperature of high-voltage and ultra-high-voltage power equipment such as gas-filled circuit breakers, vacuum circuit breakers, and frame circuit breakers.

[0023] Specifically, refer to Figure 1 and Figure 2 The antenna structure includes a mounting flange 1, an RFID assembly, and an antenna assembly 3, with the RFID assembly and antenna assembly 3 respectively located at both ends of the axial direction of the mounting flange 1.

[0024] Mounting flange 1 is used to connect with the device under test. If necessary, the device under test is provided with a connecting flange on the outside, which can be connected to mounting flange 1 by bolts. The connecting flange has a through hole in the middle that communicates with the inside of the device under test. When mounting flange 1 is connected to connecting flange, RFID component enters the inside of device under test through through hole, and then RFID component can obtain the temperature information inside device under test.

[0025] In some embodiments, the through hole of the connecting flange can be the inspection port of the equipment to be tested. When the connecting flange is not used to install the mounting flange 1, the outer cover of the connecting flange is used to close the inspection port.

[0026] Reference Figure 3 The RFID component includes a housing 2 and an RFID chip 21 disposed inside the housing 2. The housing 2 has a cylindrical structure and is hollow inside for housing the RFID chip 21. A groove 11 is recessed in the middle of the mounting flange 1. One axial end of the housing 2 is embedded in the groove 11 to form a snap-fit ​​limit. Furthermore, the housing 2 and the inner wall of the groove 11 are fixed by screws or rivets to fix the housing 2 and the mounting flange 1.

[0028] Furthermore, a first annular sealing ring 12 is provided circumferentially inside the groove 11. When the housing 2 is installed with the mounting flange 1, the two sides of the first sealing ring 12 deform and abut against the inner wall of the groove 11 and the circumferential edge of the housing 2, respectively, forming a reliable seal to ensure the sealing inside the housing 2 and prevent the RFID chip 21 from being affected.

[0029] Reference Figure 4 The antenna assembly 3 includes a mounting plate 31 and a protective shell 32. The protective shell 32 is fixedly mounted on the mounting plate 31. A radio frequency antenna 33 is installed inside the protective shell 32. The mounting plate 31 is fastened to the mounting flange 1 by screws. A circular hole is opened in the middle of the mounting flange 1 along the axial direction. One end of the circular hole is located in the middle of the groove 11, so that one end of the radio frequency antenna 33 passes through the circular hole and enters the outer shell 2, thereby connecting with the RFID chip 21. After the RFID chip 21 obtains the temperature data inside the device to be tested, it transmits it to the outside through the radio frequency antenna 33.

[0030] A second sealing ring 34 is also provided on the side of the mounting plate 31 facing the mounting flange 1. When the mounting plate 31 is connected to the mounting flange 1, the second sealing ring 34 is located on the outer periphery of the circular hole, thereby providing a circumferential seal for this side of the circular hole.
