Abstract
The utility model discloses a piston electric leakage breaker which includes a shell body, and a static contact and a moving contact disposed therein. A driving disc and a piston pipe are also disposed inside the shell body. The driving disc is provided with a drive push rod; the static contact is disposed inside the piston pipe; and the moving contact is disposed on the drive push rod. The driving push rod is telescopically disposed inside the piston pipe. Driven by the telescopically drive push rod, the moving contact is connected to or disconnected from the static contact. The piston electric leakage breaker is simple in structure, is relatively reasonable in design, and is provided with a piston pipe, wherein the moving contact and the static contact are disposed inside the piston pipe so that the motion controlling precision can be enhanced significantly. The piston electric leakage breaker is strong in operating stability and applicability.
