| Zusammenfassung: | The invention relates to a local discharging detection device and method employing electromagnetic reflection cavity. The local discharging detection device employing the electromagnetic reflection cavity comprises a local discharging detection antenna (2), a signal reflection cavity (1) and a signal detection unit (3), wherein the local discharging detection antenna (2) is arranged in the signalreflection cavity (1), and the signal detection unit (3) is connected with the built-in local discharging detection antenna (2). With the integral design of the signal detection unit and the signal reflection cavity, the interference of a signal transmission line is reduced; the local discharging detection antenna is arranged in the signal reflection cavity, the signal reflection cavity is used for reflecting an electromagnetic wave with a special frequency for many times, resonance is generated on excitation of the built-in local discharging detection antenna, the local discharging detectionsignal is expanded, and th |
