Abstract: The present disclosure discloses a distributed capacitance energy absorption verification device, which belongs to the field of direct-current high-voltage surge suppression. The distributed capacitance energy absorption verification device mainly includes a direct-current high-voltage generator, a high-voltage switch, a high-voltage capacitor bank, an isolation transformer, an energy absorption device, a high-voltage sphere gap short-circuit switch and other components. The high-voltage capacitor bank is used for simulating a distributed capacitance, and the high-voltage sphere gap short-circuit switch is used for simulating a short-circuit fault of a direct-current high-voltage system, thereby implementing performance verification of the energy absorption device.

Abstract: A waterproof shoe and a manufacturing method for the waterproof shoe are disclosed. The waterproof shoe includes a waterproof shoe upper, a sealing layer and a shoe sole. A bottom portion of the waterproof shoe upper is open and is provided with a connecting member for limiting a periphery of the bottom portion of the waterproof shoe upper from extending outwardly. The connecting member connects a plurality of positions on the periphery of the bottom portion of the waterproof shoe upper. The sealing layer is injection-molded at the bottom portion of the waterproof shoe upper and penetrates into the periphery of the bottom portion of the waterproof shoe upper. The sealing layer and the waterproof shoe upper are enclosed to form a waterproof shoe cover with a sealed bottom portion.
