Description

Technical Field

[0001] This utility model relates to the field of wireless temperature sensor technology, specifically to an integrated contact temperature sensor structure based on RFID. Background Technology

[0002] RFID temperature measurement technology, or Radio Frequency Identification wireless temperature measurement technology, is a wireless temperature measurement method based on radio frequency signal propagation. It transmits wireless signals from a transmitter to a receiver, enabling remote, non-contact temperature measurement. The core of RFID temperature measurement technology is the RFID chip, which converts temperature information into electrical signals and transmits the temperature data to a reader via wireless communication technology. The reader then transmits the data to a computer for processing and analysis.

[0003] Currently, the main installation method for existing RFID moving contact temperature sensors is to clip them onto the moving contact of the switchgear circuit breaker. However, this creates a gap between the sensor and the circuit breaker moving contact, allowing heat to dissipate and resulting in large temperature measurement accuracy errors. Furthermore, installing the temperature sensor separately on the circuit breaker moving contact alters the high-voltage electromagnetic field environment, posing certain safety hazards. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an integrated contact temperature sensor structure based on RFID technology to solve the aforementioned problems.

[0005] This utility model provides the following technical solution:

[0006] An integrated contact temperature sensor structure based on RFID technology includes an upper shell, a lower shell, a steel sheet, an RFID temperature measurement circuit, and screws; the RFID temperature measurement circuit is equipped with a temperature probe, the RFID temperature measurement circuit is placed between the upper shell and the lower shell, and the upper shell and the lower shell are fixed to the steel sheet by the screws.

[0007] Furthermore, the upper shell is provided with an inner groove to accommodate the RFID temperature measurement circuit.

[0008] Furthermore, the RFID temperature measuring circuit is clamped by the limiting point on the lower shell and the inner groove.

[0009] Furthermore, the lower shell is provided with a probe opening, and the steel sheet is provided with a square opening, through which the temperature probe passes and is placed inside the square opening.

[0010] Furthermore, the square opening is provided with thermally conductive silicone rubber.

[0011] Furthermore, the screw hole provided on the upper shell and the round hole provided on the lower shell correspond to the threaded hole provided on the steel sheet, and the screw is fixed on the threaded hole by passing through the screw hole and the round hole.

[0012] This utility model also discloses a contact component inside a high-voltage cabinet, including a stationary contact, a moving contact, and a plum blossom contact. One of the contact steel plates of the plum blossom contact is a contact temperature sensor structure based on RFID technology as described in any of the aforementioned technical solutions.

[0013] This utility model has the following beneficial technical effects:

[0014] The temperature sensor structure of this utility model is integrated with the plum blossom contact, and the temperature sensor can be directly installed in the plum blossom contact at the factory. It is also securely fixed with screws. The integrated temperature sensor structure has less impact on the high voltage electromagnetic field environment and has high temperature measurement accuracy.

[0015] The temperature sensor structure of this utility model is easy to install. Since the temperature measuring component is installed in the middle part of the contact steel sheet, it avoids the installation path of the bracket and spring when installing the plum blossom contact, and its installation method is no different from that of the normal contact steel sheet.
