Problems solved by technology

Operators can check the use status of the grounding wire through the display screen of the safety tool cabinet, but the safety tool cabinet can only display the use status of the grounding wire that is not in the cabinet as the working state, and cannot determine whether the grounding wire is in a free state

Abstract

The invention relates to a portable substation grounding wire state monitoring device. The portable substation grounding wire state monitoring device is characterized by comprising an annular gasket pressure sensor, a singlechip U1 and a liquid crystal display module, wherein the output end of the annular gasket pressure sensor is connected with the corresponding input end of the singlechip U1; the annular gasket pressure sensor and the tail end of a suspended substation grounding wire are fixed to a wiring column; and the output end of the singlechip U1 is connected with the input end of the liquid crystal display module. The portable substation grounding wire state monitoring device has the benefits of small volume and convenience for use and carrying; a grounding wire state can be mastered in real time; a grounding wire can be generally managed; and the switch-on accident with the grounding wire is avoided.

Description

technical field [0001] The invention relates to a portable substation ground wire state monitoring device and a realization method. Background technique [0002] At present, the main means to prevent the closing accidents of substations with grounding wires is to strengthen the management of the grounding wires and rely on the subjective ability of the staff to solve this problem. In fact, due to the large number of grounding wires, the wide range of connection and the layered arrangement of equipment, the grounding wires are not easy to manage and easy to be exposed. In addition, if the grounding wire is removed and not returned to the safety tool cabinet in the substation in time, it is easy to cause misjudgment by the operating personnel. Since the staff will inevitably make mistakes in their usual work, manual management cannot completely prevent closing accidents with grounding wires. [0003] In terms of technology, the more advanced method for managing grounding wir...
