一种输电线路防外力破坏警示装置
摘要：
本发明涉及一种输电线路防外力破坏警示装置，包括固定环、外壳和屏蔽层，所述固定环设于所述外壳的顶部，所述外壳的底部或侧面上涂覆有所述屏蔽层，所述外壳内设有第一二极管、第二二极管、第一发光二极管、第二发光二极管、第一触发二极管、第二触发二极管、第一限流电阻、第二限流电阻、第一积分电容和第二积分电容。本发明的输电线路防外力破坏警示装置，具备不定周期闪光和物体接近时声光报警功能，防外力破坏事故的警示作用更为优越。
摘要（英）：

The invention relates to a device for warning a power transmission line to be damaged by external force. The device comprises a fixing ring, a shell and a shielding layer, the fixing ring is arranged at the top of the shell, the shielding layer is coated at the bottom or on the side face of the shell, and a first diode, a second diode, a first light emitting diode, a second light emitting diode, a first trigger diode, a second trigger diode, a first current-limiting resistor, a second current-limiting resistor, a first integrating capacitor and a second integrating capacitor. The device has a function of irregular glittering and a function of acousto-optic alarming when an object approaches, and is better in effect of warning the power transmission line to be damaged by external force.
