Abstract

The invention discloses a power switch action life testing device which comprises a box body, an action part, a controller and a limiting groove body, the limiting groove body is detachably mounted at one end in the box body, the controller is mounted at the other end in the box body, the action part is arranged below the limiting groove body, and a power switch is embedded in the upper part of the limiting groove body; the action part is composed of a pushing mechanism, an adjustable pushing pulley and a driving air cylinder, the adjustable pushing pulley is movably installed at one end of the pushing mechanism, the other end of the pushing mechanism is connected with the driving air cylinder, an operation handle of the power switch is embedded between the adjustable pushing pulley and the pushing mechanism, and the controller is connected with the driving air cylinder and the power switch. The device has the characteristics of automatically detecting the service life of the power switch, reducing the labor intensity of personnel, saving human resources, introducing automatic testing to avoid the manual safety problem of live testing and the like.

Description

technical field [0001] The invention relates to the technical field of power switch testing, in particular to a power switch action life testing device. Background technique [0002] The built-in wall air conditioner power switch is a switch suitable for switching on and off the power supply of high-power air conditioners (3P). Its key characteristic parameters "switch life" and "conductivity" are important test items for its reliability. Its quality directly determines whether the air conditioner can be turned on and used normally, and it belongs to the unitary quality factor. [0003] At present, there is no automatic test device for its "switch life" and "conductivity". It only relies on manual switching of the switch, and then uses a multimeter to test its continuity. If necessary, connect a large current in series to test its high-current conduction reliability. As a whole, it is impossible to realize a stable and safe automatic test to record whether its life meets t...
