The utility model relates to electric automobile access stake circuit safety technical field especially, and more particularly to a kind of electric automobile access stake
power grid short-
circuit protection device.The utility model provides a kind of electric automobile access stake
power grid short-
circuit protection device, which can eliminate the
electric arc generated inside the circuit protector when power off, and can also speed up the heat dissipation efficiency inside the circuit protector.A kind of electric automobile access stake
power grid short-
circuit protection device, including circuit protector and installation frame etc., the right side of circuit protector is connected with installation frame.The utility model
extrusion frame moves downward at the same time,
extrusion sliding frame moves left, so that arc extinguishing grid moves left and enters inside circuit protector, the
electric arc generated when power off is eliminated, and at the same time, the upper heat dissipation groove of circuit protector is opened, so that heat is dissipated outward, which achieves the effect of eliminating the
electric arc generated inside the circuit protector when power off, and speeding up the heat dissipation efficiency inside the circuit protector.
