1. High voltage AC fuse

advantage:

It has simple structure, small size, cheap price and easy maintenance.

When the current exceeds a given value for a certain period of time, the specially designed fuse can melt and break the circuit. The protection action is reliable and the short-circuit fault can be eliminated in a short time.

shortcoming:

Traditional high-voltage AC fuses may have poor performance in terms of anti-pollution and salt resistance because they are generally not fully insulated equipment and the live parts are exposed to the environment.

2. Outdoor high-voltage closed jet fuse

advantage:

The main body adopts an integrated closed porcelain bottle, which has good electrical insulation, safety and strong bending resistance, achieving true full sealing and full insulation.

It is equipped with reflective stickers and position sensors for dual monitoring, which can effectively monitor the on-off status of the fuse in the fuse tube. It is easy to operate, safe, reliable, and easy to maintain.

The use of fully insulated devices enhances the fuse's resistance to dirt and salt, and extends the service life of the fuse.

In the power distribution installation and maintenance project of power transformers, the new spray-type high-voltage fuse can visually observe the intact state of the high-voltage fuse, thereby judging the working condition of the high-voltage fuse, handling faults in a timely and accurate manner, and improving distribution The reliability of the power supply of the electric transformer makes the operation safer, more intuitive, more convenient and faster, and reduces the labor intensity of power maintenance operators.

Disadvantages: No obvious shortcomings have been clearly stated yet.

advantage:

In a high-voltage DC environment, in order to confirm the fuse's fusing performance under extremely high di/dt conditions, three large-rated current fuses can be tested in parallel, which has applicability in specific high-demand DC environments. 3. High-speed parallel DC fuses for HVDC protection

Disadvantages: Common disadvantages of this type of fuse are not explicitly mentioned.

4. High voltage fuse with aluminum fuse element

advantage:

Used for overcurrent protection in most electrical installations, providing the highest degree of protection at the lowest initial cost.

Disadvantages: The general shortcomings of this type of fuse are not explicitly mentioned, but there may be some relative shortcomings in the comparative study with copper fuses, but the article does not clearly indicate what specific aspects these shortcomings are.

Generally speaking, different types of high-voltage fuses have their own unique advantages and applicable scenarios in practical applications. At the same time, there may also be some shortcomings that need to be considered based on specific application conditions. When selecting a high-voltage fuse, it is necessary to comprehensively consider the requirements of the electrical system, environmental conditions, cost and other factors to ensure that the most appropriate fuse type is selected to achieve effective circuit protection.
