Energy-saving residual current circuit breaker

Abstract

An energy-saving residual current circuit breaker comprises an experimental device. The experimental device comprises an experimental button, an experimental movable sheet, an experimental static sheet, a reset spring and an experimental lead, wherein the experimental button is sleeved on a residual current circuit breaker shell in a sliding way, the reset spring is sleeved on a guide rod of the experimental button, the experimental movable sheet is arranged right below the experimental button, the experimental static sheet is fixed at one side of the experimental movable sheet, and the lower end of the guide rod of the experimental button props against or deviates from an inclined surface arranged on the experimental movable sheet; when the lower end of the guide rod of the experimental button props against the inclined surface arranged on the experimental movable sheet, the experimental movable sheet and the experimental static sheet are in fit contact; and when the lower end of the guide rod of the experimental button deviates from the inclined surface arranged on the experimental movable sheet, the experimental movable sheet and the experimental static sheet are separated and deviated. The energy-saving residual current circuit breaker is convenient to operate, is attractive in appearance and has high reliability and long service life, false tripping caused by starting impact current generated in a circuit can be solved by an electronic control system, residual action current is effectively detected, inconvenience brought to a user is avoided, consumption is reduced, and energy is saved..

Description

technical field [0001] The invention relates to a circuit protection circuit breaker, in particular to a household energy-saving leakage circuit breaker. Background technique [0002] The leakage induction and action response speed of the leakage circuit breaker in the prior art is slow, which often leads to misjudgment and malfunction. In order to verify the effectiveness of the leakage induction and action response of the leakage circuit breaker, an experimental button is provided for testing. The leakage circuit breaker under the latest technology will be damaged due to the temperature rise of the tripping coil when the experiment or the protection action is used, and the anti-electromagnetic compatibility is poor. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides an energy-saving leakage circuit breaker. [0004] In order to achieve the above object, the technical solution adopted by the present invention to solve i...
