Description

Technical Field

[0001] The utility model relates to the field of switches, in particular to a fuse-type switch. Background Art

[0002] A fuse switch, also known as a fuse switch or fuse switchgear, is an electrical device that combines a fuse with a switch. It is commonly used in power systems to provide overload and short-circuit protection. The following is a detailed introduction to fuse switches:

[0003] Working principle:

[0004] The basic operating principle of a fuse switch is to disconnect the circuit by melting the fuse element when an overcurrent or short circuit occurs, thereby protecting electrical equipment from damage. When the current is normal, the switch is closed, allowing current to flow normally. When the current exceeds the fuse's rated value, the fuse element melts due to excessive heat, cutting off the current.

[0005] Structural composition:

[0006] A fuse switch usually consists of the following parts:

[0007] Fuse: A component used to protect circuits, usually consisting of a fuse or a fuse link.

[0008] Switching mechanism: used to control the opening and closing of a circuit, usually manually or automatically operated.

[0009] Housing: An outer shell of insulating material that protects internal components.

[0010] Connection terminals: used to connect cables and other electrical equipment.

[0011] advantage:

[0012] Strong protection function: can effectively prevent equipment damage caused by overload and short circuit.

[0013] Easy to use: easy to operate and relatively easy to maintain.

[0014] Economical and practical: Compared with other complex protection devices, fuse switches are relatively cheap.

[0015] The cover of the existing switch housing is usually hinged to the base, which is inconvenient to remove during maintenance or other operations.

[0016] Therefore, there is an urgent need to provide an improved technical solution to solve the above technical problems. Utility Model Content

The cover 2 is a flip-up type and is hinged to the base 1 by a horse head 10. A knife for closing the switch is provided on the back of the cover 2. The knife and the specific structure for installing the knife are not limited. The knife is matched with the fuse, that is, the contacts at both ends of the fuse are connected to the knife, and the base 1 at both ends of the fuse is relatively positioned. Two corresponding static contact knife seats are provided. The face cover 2 includes a main body 4, which is a transparent panel, and a plurality of reinforcing ribs are provided inside the transparent panel for increasing the strength of the face cover 2. A handle 5 is provided on the top of the face cover 2, and the handle 5 protrudes from the surface of the face cover 2 and faces forward.
