Moving contact and corresponding fixed contact close timesharing and promote rotating shaft and rotate, and rotating shaft drives bearing pin and rotates around it the center and rotate, and bearing pin drives push rod and moves up and down.
When moving on the push rod, promote with its on the indication piece of end in contact, the fixed pivot that makes indication piece center on itself turns an angle; When push rod moved down, separated with indication piece the upper end of push rod, and indication piece no longer is subjected to push rod thrust, resets under the torsion of back-moving spring; Be converted into swinging of indication piece by moving up and down of push rod, show the branch state that closes of contact of breaker.Pilot hole is set on push rod, lead is arranged in pilot hole.
Existing breaker of plastic casing handle mainly contains two big functions: the one, and operating function I promptly realizes breaker closing, separating brake, detains; The 2nd, indication function II promptly rests in particular location on the breaker cover with handle, in conjunction with indicating on the breaker cover that 0,1 judges that contact of breaker closes branch, if rest in the middle of the sign 0 and 1, shows that breaker mechanism is in trip status again, and contact separately.And among the function II contact to close branch indication all be by the transmission of breaker mechanism action displacement, there is major hidden danger in this deixis.The present invention can close by contact of breaker and assign to show breaker closing, separating brake, the actual response virtual condition.
The present invention's custom that breaks traditions, on original project organization, keep original operating function I of handle and deixis II, increase by a cover and can show correctly that the breaker of plastic casing contact closes the device of branch, do not influence original function, form the relatively independent device of two covers, provide reliable assurance, guarantee safety utilization of electric power for contact of breaker closes the branch demonstration.
This principle of device is simple, is to produce displacement by the rotating shaft left-right rotation, utilizes theory of mechanics that rotation displacement is converted into and moves up and down displacement, will move up and down displacement again and be converted into the displacement that swings, and realizes that circuit breaker closes branch and shows.
