摘要

戶外產品設備用途越趨廣泛，長時間置於戶外空間恐面臨嚴苛環境帶來的影響，故產品設計上需確保其具備可承受上述環境條件之可靠度。變壓器多設置並暴露於各種室外環境。變壓器為影響終端用戶能否享受用電品質的關鍵設備，定期盤點及檢驗成為電力公司的重點工作。無線射頻辨識系統主要由電子標籤、讀取器與應用系統所組成，將資料儲存於電子標籤，並以無線方式進行資料傳輸。利用RFID技術取代傳統銘牌刻印方式，可提升工作效率及方便性。
本研究針對變壓器銘牌之RFID標籤，考量該產品可能面臨到之各種環境應力，提出組合試驗項目之測試模式，並決定適當之試驗參數。研究中參考MIL-STD-105E規範，建構允收拒收準則作為組合試驗允拒收判斷參考依據。結果顯示，所有樣本皆能維持良好功能運作，試驗結果判定為允收，表示RFID標籤具備適當可靠度水準並得以導入於使用環境。在防塵與防水試驗方面， RFID樣本功能皆可維持正常運作，但在外殼防護方面，呈現水漬及灰塵滲入，表示外殼防護能力不足。本研究針對防盜模組所含之防盜鞘與陶瓷基板進行強度測試，結果顯示，陶瓷基板強度遠低於防盜鞘強度，當承受外力拉扯防盜鞘時，陶瓷基板會先發生碎裂，以確保儲存於RFID晶片之資料安全無虞，不至遭竊取或竄改。

Outdoor Equipment increasingly widespread use, long placed outdoors space brought fear to face the impact of harsh environment, so the design must ensure that their products have to withstand the environmental conditions of the reliability of the above. Power delivery process, transformers and more exposed to a variety of settings and outdoor environments. Transformer can affect the end-user to enjoy the quality of the electricity key equipment, inventory and inspection became a regular power company priorities. RFID systems (Radio Frequency Identification; RFID) mainly consists of electronic tags (Tag), the reader (Reader) and application (Application System) composed of the data stored in the electronic label, and wireless data transmission. The use of RFID technology to replace the traditional engraved nameplate way to improve work efficiency and convenience.
In this study, the transformer nameplate of RFID tags, consider the product may face a variety of environmental stresses to the proposed pilot project to test a combination of model and determine the appropriate test parameters. Study reference MIL-STD-105E specifications, to construct a fair income declined as a combination of the criteria allowed to reject the test to determine the reference basis. The results showed that all samples have encountered maintaining good functional operation of the test results judged to acceptance, which means that RFID tags have the appropriate level of reliability and can be imported to the use of the environment. In terms of dust and waterproof test, RFID sample functions can maintain normal operation, but in terms of protective shell, showing water stains and dust infiltration, said inadequate housing protection. In addition, this study burglar alarm module sheath and contained in the ceramic substrate for the strength test, the results show much less than the strength of the ceramic substrate theft sheath strength when subjected to an external force pulling the sheath security, fragmentation of the ceramic substrate will first occur to to ensure that the information stored in the RFID chip is safe, not to theft or tampering.
