Description

technical field [0001] The invention belongs to the technical field of photovoltaic components, and in particular relates to a fault fire detection circuit for photovoltaic components. Background technique [0002] The existing photovoltaic module breaker only monitors the voltage and current of the photovoltaic module. If any problem is found, it directly controls the relay to perform the shutdown operation to disconnect this group of photovoltaic modules from other photovoltaic modules. With the gradual expansion of the scope of use of photovoltaic modules, the requirements for the function of photovoltaic module switchers have also been further improved. In order to design a photovoltaic module switch-off host with good use effect, it is necessary to design a photovoltaic module fault fire detection circuit. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present invention provides a photovoltaic module fault fire detection circuit with good use ef...
