Intelligent circuit breaker combined device

ActiveCN105513915AOvercome failureLower internal resistanceSnap-action arrangementsContactsIntelligent controlPower consumption

The invention provides an intelligent circuit breaker combined device. A current detecting piece is arranged in a circuit breaker. The current value of a circuit in the circuit breaker is obtained through the current detecting piece and then sent into a controller of an intelligent control device on one side of the circuit breaker, and the controller makes a judgment according to the received current value, and controls and starts an action mechanism to drive the circuit breaker to be released when the current value is in an overload state for a period of time. Because the current value of the circuit in the circuit breaker is directly tested and the controller is used for intelligent control, the problem that a thermal releaser is prone to fails caused by the external environment air temperature influences is solved. Meanwhile, due to the fact that the thermal releaser is omitted, the internal resistance of the circuit breaker is greatly reduced, and the power consumption and the heating amount of the circuit breaker are reduced. In addition, the controller is independently arranged in the intelligent control device outside the circuit breaker, the problem that a controller can not be put in a narrow space of a circuit breaker is solved, and meanwhile it can be avoided that the work of a controller is influenced by strong current.

The invention discloses an embedded maintenance operation platform with a false connection electric shock preventive function for backlight modules of display screens. The embedded maintenance operation platform structurally comprises a support bottom plate and antiskid feet. The embedded maintenance operation platform with the false connection electric shock preventive function for the backlightmodules of the display screens has the advantages that the rowed backlight modules on the display screens can be pushed and led into a platform when the rowed backlight modules need to be tested and maintained, a transverse plate and guide wheels are matched with one another, accordingly, the orientation of maintenance elements can be prevented from being easily deviated when the rowed backlight modules are led into the platform, and the maintenance elements can be stably connected with a rowed wiring board; a swing rod, a fixture block and clamp plates are matched with one another, accordingly, the backlight modules can be completely led into tests and can be conveniently and quickly taken out, and the problem of electric shock due to the fact that electrified ends of existing backlight modules are exposed and gripping fingers touch the electrified ends when the existing backlight modules are taken out can be effectively solved; restraint plates and antislip particles can be contracted, the backlight modules can be restrained and fastened, unstable contact of the repeatedly started and stopped backlight modules due to cold and heat can be prevented, accordingly, the backlight modules can stably run during test and maintenance, and effects of protecting equipment can be realized.
