In the rectangular v notch v on right side, when tripping mechanism is threaded off, this snap fit of rotation due to action link rod will be disengaged from action link rod, and
Jump on described reset key is rapid in the presence of built-in compression spring.
Preferably, the lower right side of described reset key is provided with a stable steering hammer, when being beneficial to reset key action
Jump along in the right side wall balance slip of mounting base, in described reset key, empty rectangular internal compression spring one end is pressed on
The top of empty cuboid in reset key, other end card is pressed on the mounting platform of mounting base compression spring, works as reset key
Snap fit depart from action link rod after by compression spring, its rapid release is jumped.
Preferably, described mounting base is provided with four pinch plates, in order to fixing described electric magnet, in upper right
Side is provided with the installation cavity of reset key and the mounting platform of compression spring, and lower right side is provided with arcuate groove, in middle part setting
There is perforation round platform, action link rod vertical rotation is arranged on described peace by rotating shaft by the indent round platform in order to insert action connecting rod
On dress base plate.
The operation principle of described RCD trip action mechanism is as follows：
After the electric magnet of tripping mechanism receives trip action signal, the action iron core action of electric magnet, drive its end
The sheathed action link rod in portion rotates, and now the snap fit on the left of described reset key departs from action link rod, and one side reset key exists
Upper jump rapidly under the top pressure of inner chamber compression spring, the side pole of simultaneously described action link rod extreme ends evagination drives the disconnected of adjacent pole
Road device is threaded off and is completed the power-off protection to load；When loaded line fix a breakdown need to restore electricity when by artificial by adjacent pole
Breaker closing, under the reset key being simultaneously under trip status by and make tripping mechanism be in chopper and normally power
State.
The beneficial effect of this RCD trip action mechanism is：
The electric magnet fixation of this tripping mechanism, the action link rod of tripping mechanism and reset key are reasonable in design, structure
Simply, stable and reliable in work.
