Automatic replacement device of fuse used for power distribution cabinet

Abstract

The invention discloses an automatic replacement device of a fuse used for a power distribution cabinet. The device comprises a machine body. A storage box is arranged on a top of the machine body, first gears are arranged on two sides of one end of the storage box, and an object inlet slot is arranged at a position of the top of the machine body, wherein the position is near the first gears. Guide rails are arranged on the two sides of an internal portion of the object inlet slot, a second gear is arranged on a bottom of each first gear, and a rotating ring is arranged on one side of the second gear. In the invention, a rotation shaft is used to drive the storage box to rotate to the position of the object inlet slot. Through a frame of the object inlet slot, a telescopic block is extruded so as to drive a slide rod to slide. A pressure spring pushes a fusing block into the machine body through a top plate. The first gears drive a rotation ring to rotate. The second gears drive a third gear to rotate. A slide plate moves towards one side of a clamping plate. The device has advantages that an intact fuse link can be stored in equipment and the fuse link can be replaced automatically 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...
