Abstract
The utility model discloses a double-pole seesaw-type breaker, which comprises a seesaw, an outer shell and an electromagnetic mechanism, a tripping mechanism, an arc extinguish chamber, a moving contact and a fixed contact which are arranged in the outer shell. The top end of the electromagnetic mechanism is provided with an armature. The tripping mechanism comprises a bracket, a connecting plate, a buckle, an interlocking component, a spring and an intermediate clapboard. Both the armature and the seesaw are hinged on the bracket. The bracket is also hinged with the connecting plate and the buckle. The connecting plate and the buckle are also hinged. The connecting plate is connected with the interlocking component. The other end of the interlocking component is provided with the spring. The spring is connected with the intermediate clapboard onto the outer shell. The moving contact is hinged on the connecting plate. The fixed contact is arranged at the position corresponding to the moving contact on the outer shell of the bottom of the arc extinguish chamber. The outer shell of the arc extinguish chamber is provided with an arc discharge groove. The design of the arc discharge groove and the mechanical interlocking between poles of the double-pole seesaw-type breaker of the utility model not only improve the breaking capacity of the breaker, but also make the installation more convenient and reliable.
