Background

As is well known, a disconnecting switch (commonly called "knife switch") is one of the most used electrical appliances, and its operating principle and structure are relatively simple, and the disconnecting switch can open a circuit, interrupt current or make it flow to an electronic component of another circuit. The most common disconnectors are electromechanical devices operated by a person, in which there are one or several electrical contacts. The "closed" of a contact means that the electronic contact is conductive, allowing current to flow; an "open" of the switch indicates that the electrical contact is not conductive, creating an open circuit, and not allowing current to flow.

The existing grounding wire of the isolating switch does not have an automatic detection device, the grounding wire and the grounding rod are outdoor for a long time, and are influenced by external factors, so that the grounding rod and the grounding wire are easy to corrode.
