Electric equipment protection guardrail
The invention relates to an electric equipment protection guardrail, which comprises a positioning groove, at least two transmission upright posts, a protection guardrail, photosensitive sensors, a warning buzzer and a control circuit, wherein the cross section of the positioning groove is in a shape like the Chinese character 'ao'; the transmission upright posts, the protection guardrail, the photosensitive sensors, the warning buzzer and the control circuit are embedded in a groove of the positioning groove; the tail end of each transmission upright post is hinged to the positioning groove; the side surface of each transmission upright post is hinged to the protection guardrail; the photosensitive sensors are symmetrically distributed on the upper end surface of the positioning groove by using the center line of the positioning groove as a symmetry axis; the control circuit is electrically connected with the photosensitive sensors and the warning buzzer; and the control circuit is electrically connected with a lead-in bus used for power protection. The electric equipment protection guardrail has the advantages that the occupied field area is small; the adaptability to the field is high; the electric equipment can be isolated; and meanwhile, whether the electric equipment is in an electrification state or not can be monitored, so that the isolation reliability of the electric equipment is improved, the electric equipment can be effectively monitored, and the warning is realized.
