Problems solved by technology

[0002] Cartridge fuses are also called fuses. The IEC127 standard defines it as a "fuse link". It is an electrical component installed in a circuit to ensure the safe operation of the circuit. Cartridge fuses are widely used in high and low voltage power distribution systems. And control systems, as well as electrical equipment, as a short-circuit and over-current protector, is one of the most commonly used protection devices. At present, most box-type fuses are not waterproof, and short-circuits are prone to occur in humid environments, affecting Electricity is safe, so we propose a box fuse suitable for wet environments to solve the above problems

Abstract

The invention discloses a box-type fuse for a wet environment, which includes a box-type fuse. A base is arranged below the box-type fuse. A placing box with an open top is placed on the top of the base. The box-type fuse is disposed in the placing box. A first rotating plate is rotationally mounted on one side of the top of the placing box. The first rotating plate is provided with rotating slotson the two sides. A rotating shaft is rotationally mounted in each rotating slot. A sliding slot is arranged in the inner wall of one side of each rotating slot near the box-type fuse. Second rotating plates are respectively welded to the ends of the two rotating shafts away from each other. Two groups of cylindrical holes are arranged in the inner wall of one side of the placing box near the second rotating plates. The box-type fuse is highly practical. Through the rotating slots and the cylindrical holes, the second rotating plates can be easily moved and fixed. Through springs and fixing plates, the box-type fuse can be easily dried while the second rotating plates are fixed, and the electricity safety is ensured.
