ELECTRONIC CIRCUIT BREAKER HAVING MIS-OPERATION PREVENTING FUNCTION

摘要

PURPOSE: electronic circuit breaker (model casing circuit-breaker) operation has the function of that mistake prevents from being provided to improve reliability and safety, when panel tissue. CONSTITUTION: molding case circuit-breaker includes: the electric current (R. that current detecting equipment detects each phaseS, T) from the three-phase of General Electric's power; Rectifying part (10) rectifies and exports the electric current; Constant power components (20); Reverse amplifier unit (30); Transient current test section (40) drives buckle releaser (80); The output of analog-digital converter (50) is digital signal to be become; And a kind of part (100) interception electric power for preventing maloperation passes through decision to upper power blocking apparatus, it has a defect, if power is not intercepted, the control signal is being transmitted to buckle releaser from microprocessor (70) and by stablizing the time.
