Abstract

The invention relates to the technical field of breaker control circuits, and particularly relates to a self-restoring over / under voltage breaker controller circuit. The circuit ensures that sufficient energy can be provided to a motor to drive a breaker to release by additionally providing an energy storage circuit when a main circuit is in under voltage or voltage loss and the delay time is out;a redundant clock circuit is adopted to ensure that a backup clock is immediately started under the circumstance that the main clock of a system is failed, and the system can be more stable and reliable; and the whole circuit has simple design, high electromagnetic compatibility resistance and low working temperature, can meet the requirement of high reliability, and is suitable for the actual requirement for small special volume and small circuit board storage space of a self-restoring over / under voltage small breaker.

Description

technical field [0001] The present application relates to the technical field of circuit breaker controller circuits, in particular to a self-recovery overvoltage and undervoltage circuit breaker controller circuit. Background technique [0002] With the increase of national support and the maturity of photovoltaic technology, more and more photovoltaic power generation has entered ordinary households. However, due to some objective factors, the problem of damage to household appliances occurs when the voltage is too high or too low. At the same time, it is also to solve the problem of low power quality of the grid and power outage due to system failure during grid connection. In many places, photovoltaic grid-connected boxes are installed. Self-recovery overvoltage and undervoltage protector. Although this can avoid manual frequent closing during faults, the self-recovery overvoltage and undervoltage protector itself does not have the ability to segment short-circuit curre...
