Problems solved by technology

[0004] According to the protection object, it can be divided into fuses for protecting transformers and general electrical equipment, fuses for protecting voltage transformers, fuses for protecting power capacitors, fuses for protecting semiconductor components, fuses for protecting motors, and fuses for protecting household appliances. Fuses, etc., can be divided into open type, semi-closed type, tubular type and jet type fuses according to the structure. At present, the existing fuses have complex structures, inconvenient installation and high cost.

Embodiment Construction

[0015] refer to figure 1 As shown, a tubular fuse includes a fiber tube 1, a contact piece 2 and a melting piece 3, the contact piece 2 and the melting piece 3 are arranged in the fiber tube 1, and the contact piece 2 is arranged end, the contact piece 2 is hinged with the melting piece 3, the connection between the contact piece 2 and the melting piece 3 is provided with an insulating washer 4, the upper and lower ends of the melting piece 3 are provided with V-shaped grooves 5, and the fiber tube 1 There are thread rings 6 at both ends, and nuts 7 are provided on the outside of the fuse 3. When in use, the tubular fuse is installed in the working area through the support 10, and the circuit is installed on the contact piece 2 through the wiring hole 8. On the other hand, when the circuit is overloaded, the V-shaped groove 5 on the fuse 3 will fuse quickly, so as to keep the circuit safe. The nut 7 is threadedly connected with the threaded ring 6, and the nut 7 is provided wi...

Abstract

The invention discloses a tubular fuse. The tubular fuse comprises fiber pipe, contact pieces and a fuse piece; the contact pieces and the fuse piece are arranged in the fiber pipe; the contact pieces are arranged at the two ends of the fuse piece; the contact pieces are hinged with the fuse piece; an insulating gasket is arranged in the connecting place of the contact pieces and the fuse piece; V-shaped grooves are formed in the upper and lower ends of the fuse piece; threaded rings are arranged at the two ends of the fiber pipe; a screw cap is arranged on the outer side of the fuse piece; the screw cap and the threaded rings are in threaded connection; a wiring hole is formed in the screw cap; a waterproof gasket is arranged on the outer side of the screw cap; a supporting seat is arranged below the screw cap; the supporting seat is connected with the screw cap in a clamping manner; and fixed screws are arranged on the supporting seat. The tubular fuse is simple in structure, low in cost, convenient to use, light in weight, and easy to mount.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a tubular fuse. Background technique [0002] A fuse refers to an electrical appliance that fuses the melt with the heat generated by itself and disconnects the circuit when the current exceeds the specified value. Melting, so that the circuit is disconnected; a current protector made by using this principle, the fuse is widely used in high and low voltage power distribution systems and control systems and electrical equipment, as a short circuit and overcurrent protector, is One of the most commonly used protection devices. [0003] A metal conductor is used as a melt in series in the circuit. When an overload or short-circuit current passes through the melt, it will fuse due to its own heating, thereby breaking the circuit. The fuse has a simple structure and is easy to use. It is widely used in power systems, As a protective device in various electrical equipment ...
