The invention discloses a portable microgrid fault detection device and a detection method thereof. The portable microgrid fault detection device comprises a box body and a box cover, one end of the box cover is fixed to the box body through a hinge, an electric plate and two electric clamp limiting grooves are fixed to the bottom of the box body, the electric plate is electrically connected witha test lamp. The two electric clamp limiting grooves are formed in the two sides of the electric plate respectively, a positive electrode electric clamp pen and a negative electrode electric clamp penare arranged in the two electric clamp limiting grooves respectively, the positive electrode electric clamp pen and the negative electrode electric clamp pen are connected with the electric plate through wires respectively, and the box body and the box cover are fixed through buckles. The principle of a current type fault detection method is utilized, a fault line is tested through the detectionlamp, meanwhile, the telescopic support is additionally arranged, the size of the device is reduced, and carrying and using are convenient.
Description
technical field [0001] The invention relates to a micro-grid fault detection device, in particular to a portable micro-grid fault detection device and a detection method thereof, belonging to the application field of micro-grid fault detection equipment. Background technique [0002] Microgrid, also translated as microgrid, refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc. [0003] The proposal of microgrid aims to realize the flexible and efficient application of distributed power, and solve the problem of grid connection of distributed power with a large number and various forms. The development and extension of microgrids can fully promote the large-scale access of distributed power sources and renewable energy, and realize the highly reliable supply of various energy forms for loads. Smart grid transition. [0004] Existing m...
