Product Description

Product DescriptionThis is an efficient and safe outdoor high-voltage 33kV porcelain bottle jet drop fuse, mainly used for the protection of medium and high voltage power systems. Its design combines porcelain bottle insulation material and jet arc extinguishing technology, which can quickly cut off the circuit when a fault occurs, protecting the safety of power equipment and systems.
Product Features
1. High efficiency:
The jet arc extinguishing technology can quickly cut off the fault current and reduce the power outage time.
The porcelain bottle insulation material has excellent weather resistance and insulation performance, ensuring stable operation in harsh environments.

2. Safety:
The design meets the safety standards of high-voltage power systems and can reliably cut off the current in the event of a fault to prevent equipment damage and fire risks.
The porcelain bottle shell provides additional mechanical strength and insulation protection to reduce the risk of accidental electric shock.

3. Outdoor applicability:
Temperature, humidity, pollution, etc.).
Suitable for high altitude areas (usually up to 2000 meters or more).

4. Easy maintenance:
The drop-out design makes the fuse easy to replace after operation, reducing maintenance time and cost.
The structure is simple and easy to operate, suitable for occasions with frequent operations.

Working principle

1. Normal state:
The fuse is in a closed state and the current flows normally through the fuse.

2. Fault state:
When an overload or short circuit occurs in the circuit, the fuse melts due to overheating.
After melting, the jet device of the fuse produces gas, which quickly extinguishes the arc and cuts off the current.
The drop mechanism of the fuse operates, causing the fuse to fall off the bracket, forming an obvious disconnection point, which is convenient for maintenance personnel to identify and replace.

Application scenarios

1. Distribution line protection:
Used for overload and short circuit protection of 33kV distribution lines.

2. Substation:
As a protection device for the outlet or branch line of the substation.

3. Industrial and mining enterprises:
Suitable for the power distribution system of industrial and mining enterprises, especially in occasions where frequent operations are required.

4. Rural power grid:
Used for distribution and protection of rural power grids, adapting to complex environmental conditions.

5. Outdoor high altitude areas:
Applicable to power systems in high altitude, polluted or extreme climate conditions.
