An automatic replacement device for fuses used in power distribution cabinets

Abstract

The invention discloses an automatic fuse replacement device for a power distribution cabinet, which comprises a body, a storage box is arranged on the top of the body, first gears are arranged on both sides of one end of the storage box, the top of the body A feed slot is provided near the first gear, guide rails are provided on both sides of the feed slot, a second gear is provided at the bottom of the first gear, and a rotating ring is provided on one side of the second gear . The invention drives the storage box to rotate through the rotating shaft, rotates to the position of the inlet slot, squeezes the telescopic block through the frame of the inlet slot, drives the sliding rod to move, the pressure spring pushes the fuse block to the inside of the body through the top plate, and the first gear drives When the rotating ring rotates, the second gear drives the third gear to rotate, and the sliding plate moves to one side of the clamping plate, which has the advantages of storing intact fuses in the equipment and automatically replacing fuses to ensure safety.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to an automatic replacement device for a fuse used in a power distribution cabinet. Background technique [0002] The power distribution cabinet is a power distribution equipment used for power distribution, control, metering and cable connection in the power supply system. It plays a central role in the control of the power system. On the one hand, it distributes the power transmitted from the outside, and on the other On the one hand, it plays a role in controlling the electrical equipment at the next level. The safety of the power distribution cabinet is very important. Whether it is high-voltage electrical equipment or low-voltage equipment, the circuit breaker inside the power distribution cabinet is essential. , usually divided into circuit breakers and fuses. Fuses are widely used in power grid protection and electrical equipment protection. When a short c...
