In this article, the HV Fuse manufacturer will tell you about the introduction, voltage level, type, and usage scenarios of fuses.
Introduction to fuses
HV Fuse manufacturer tells you, the fuse is a device used to protect electrical circuits from overcurrent and short circuits. It prevents circuit overloads and fires by breaking the circuit when the current exceeds safe limits.
Fuse voltage rating
The voltage rating of a fuse refers to the highest voltage that the fuse can withstand. Common fuse voltage levels include low voltage fuses (LV) and high voltage fuses (HV). Low-voltage fuses are commonly used in homes and businesses, and their voltage levels are generally 230V or 400V. High-voltage fuses are used in industrial and power systems, and their voltage levels can reach several thousand volts or higher.
Common fuse voltage levels
230V: used for household and commercial electricity, such as residences, office buildings, shopping malls, etc.
400V: used for household and commercial electricity, such as residences, office buildings, shopping malls, etc.
1kV: used in industrial and power systems such as factories, substations, etc.
10kV: used in industrial and power systems such as factories, substations, etc.
35kV: used in power systems, such as substations, transmission lines, etc.
Fuse type
1. Low-voltage fuse: The maximum rated voltage is 1000V, suitable for low-voltage power equipment, such as low-voltage switch cabinets, distribution boxes, etc.
2. Medium voltage fuse: The maximum rated voltage is 35kV, suitable for medium voltage switching equipment, such as load switches, circuit breakers, etc.
3. High-voltage fuse（HV Fuse）: The maximum rated voltage is 220kV, suitable for high-voltage power equipment, such as high-voltage load switches, combined electrical appliances, etc.
How many KV are high voltage fuses widely used for?
HV Fuse manufacturer tells you that high voltage fuses are widely used in power systems with voltage levels of 10 kilovolts (10kV) and above.
HV Fuse usage scenarios
Home and Commercial Electricity: Used to protect circuits from damage by overcurrent and short circuits.
Industrial and power systems: Used to protect electrical equipment and lines from overcurrent and short circuit damage, and to prevent fires.
Traffic systems: Used to protect traffic lights, electric vehicle charging piles, and other equipment from damage by overcurrent and short circuits.
Automotive and Marine: Used to protect automotive and marine circuits from overcurrent and short circuit damage.
HV Fuse manufacturer summarizes: Fuses are indispensable protection devices in power systems. Different voltage levels are suitable for different power equipment. In power systems, the selection of fuses should be comprehensively considered based on factors such as voltage level, rated current, rated short-circuit breaking capacitance and fusing characteristics to ensure that it can ensure the safety of equipment and personnel during operation.
