The utility model relates to a secondary aviation plug and particularly relates to a VEP-type secondary aviation plug special for a 10kV handcart switch transmission test. The VEP-type secondary aviation plug special for the 10kV handcart switch transmission test comprises a VEP-type secondary aviation male plug built in a 10kV handcart. The male plug is provided with a corresponding secondary aviation female plug. The secondary aviation plug is characterized in that the secondary aviation female plug is provided with four pairs of pin holes corresponding to four loops in the handcart switch transmission test, the four loops are a motor energy storage loop, a closing locking loop, an opening loop and a closing loop, the back of the secondary aviation female plug is provided with holes corresponding to the four pairs of the pin holes, the holes in the secondary aviation female plug are internally welded with insulation leads uniformly, and the insulation leads are provided with a plug corresponding to a transmission test box jack. With the VEP-type secondary aviation plug, shedding and shift of a wire clamp due to switch vibration in a test is prevented, dangers of direct current short circuit and circuit crossing are eliminated, and personal and equipment safety is guaranteed.
