The invention discloses a tool and a device for testing an insulation in-place time of a fast mechanical switch. The tool comprises a fixing device, a position adjustment device and a detection spring, and the test device comprises a vacuum arc-extinguishing chamber, an electromagnetic repulsive force structure, an oscilloscope, an intelligent control cabinet, a control loop and the tool. According to the tool and the device disclosed by the invention, the detection spring is used as a measurement medium, and by mounting the tool on the fast mechanical switch and adjusting the insulation distance according to vacuum arc-extinguishing chambers of different model numbers, the time required for the fast mechanical switch to move to the insulation distance can be quickly and accurately measured for multiple times; the tool disclosed by the invention is simple in structure and is very convenient to disassemble and assemble, the service life of the tool is prolonged by the elasticity of thedetection spring, and the
