STRUCTURE OF POWER ACCUMULATOR UNIT FIXATION FOR SWITCH Russian patent published in 2020 - IPC H01H7/10 

FIELD: electricity.

SUBSTANCE: structure of attachment of energy accumulator assembly for switch contains energy accumulator unit lever and energy accumulator spring, where one end of lever of energy accumulator unit is energy-accumulating end connected to energy accumulator spring, and other end of lever of energy accumulator unit represents drive end. An external force can be applied to the drive end so that the energy accumulator unit lever rotates around the lever support located in the middle of the energy storage unit lever to compress the energy accumulator spring on the energy storage end to complete the energy accumulation. One end of the energy accumulator spring is fixed and attached to the energy accumulator unit arm, and the other end of the energy accumulator spring is attached to the base support. In the middle of the energy accumulator lever, a power accumulator shaft is also located, which can be considered as axis of rotation. A force is applied to the drive end so that the energy accumulator unit lever rotates around the power accumulator mounting shaft.

EFFECT: design of the energy accumulator unit assembly for the circuit breaker envisaged by the present invention is characterized by simplicity of the fastening process, stability of the connection and high accuracy of the unit operation.
