Make, what this realized about 5 milliseconds (ms) is mechanically inserted the time.Closure when, the mobile contact 144 of resistor switch 11 it is initial
Speed is very slow, reaches the 40% of its traveling, and then when lever is moved towards its pivotal point, initial velocity is stepped up.Slider
143 will promote roller (22,22') in the straight profile of lever (19,19'), and this will promote the company being attached on guide wire 147
Bar (20,20'), and this will make electric arc pin 15 towards the part movement of fixed contact 145, and fixed contact 145 is in this feelings
It is tulip shape arc contact 16 under condition.
Spring (24) works during disconnecting, and has been designed so that it can be between about 67 to 100 ms
Breaking-off contact in time.For this purpose, therefore having calculated spring constant.
Damping ring (decay disk) is provided in another end of guide wire, to provide damping during opening operation.
While disconnection, lever separates with slider 143, and due to the energy being stored in during closing in compression spring, spring
Guide wire 147, guide wire 147 will be promoted further to make electric arc pin 15 move away from tulip shape contact 16.What is be fully disconnected
On position, there will be some physical distances between lever and slider 143, because damping ring will stop guide wire 147, from
And prevent the impulsive force on slider 143.
Thus the motion for carrying out autonomous interrupter (14) is sent to switch (11) using off center slider crank mechanism.
Slider and switch need not to be coaxial.Lever and link assembly are designed to rightly along the axis of the movable contact for switching
(in spite of coaxial) is moving movable contact.
