Description
technical field [0001] The invention relates to the field of LED drive protection, in particular to an intelligent DC leakage detection and surge protection device. Background technique [0002] The existing high-voltage drive LED lamps, if they want to realize leakage detection and circuit breaking and surge absorption, generally use an external leakage circuit breaker and an external surge absorption circuit, so there will be the following problems: the circuit structure is complicated and troublesome, and there is no waterproof function , easy to cause damage and malfunction. What's more, it does not have the functions of leakage detection, circuit breaking and surge absorption, which will cause lack of protection, and it is easy to directly burn out the entire line of lamps. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an intelligent direct current leakage detection and detection system with relatively si...
