Electric equipment protection guardrail

Abstract

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.

Problems solved by technology

[0002] At present, in the management of some large-scale or high-voltage and ultra-high-voltage equipment, in order to improve the safety of equipment operation and provide effective reminders to operators, it is often necessary to isolate such power equipment with protective guardrails. The currently used guardrails There are mainly fence structures and warning belts welded by metal. Although they can meet the needs of power equipment isolation, they need to occupy a large space when used, and the flexibility of their placement and removal is relatively poor. , and at the same time, it is impossible to monitor the operating status of the power equipment. In the use of electrical equipment, due to equipment failures, human reasons, etc., after the power equipment completes the power-off operation with the power supply line, it often appears that it is still charged. It is easy to cause the operator to operate the power equipment without power off, thus causing electric shock accidents. Therefore, in view of this phenomenon, it is urgent to develop a new type of power equipment protection and isolation equipment to meet the needs of actual use
