Looking To Choose A 1-100a Drop-out Fuse? These Few Places Are Enough.
In power distribution network construction, we often encounter small-capacity branch circuits, and that's where the (1 - 100 A) 33kv drop out fuse comes in very handy. Although small in size, this type of fuse is a real "tough nut to crack" in protecting transformers and branch lines. Today, we won't discuss the fancy performance parameters; let's directly look at where this thing is usually used.
The "Sentinel" on the High-Voltage Side of the Transformer
Often, these low-current fuses are directly connected to the high-voltage side of a 10kV distribution transformer. Whether in mountainous or rural areas, you'll almost always see it on any power pole with a transformer rated at a few hundred kVA or less. It acts like a loyal sentinel; if the current spikes too high due to overload or short circuit, the fuse immediately drops and breaks the circuit.
Protection of branch lines and terminal lines
Besides protecting transformers, this type of 33kv fuse is also particularly common on branch lines.
-
Branch line entrance: When a main road branches off into several smaller power lines, installing a (1-100 A) fuse allows for precise division of the protection zone.
-
Long-distance terminus: At the end of a long power supply line, this specification is perfect to prevent a small fault from draining the power supply to the entire street.
-
Temporary power supply points: For construction sites or temporary drainage pumping stations, using it as a disconnect point is convenient, cost-effective, and labor-saving.
Residential areas and agricultural irrigation
This small-capacity cover drop out fuse fuse is practically a staple in agricultural electricity. Water pumps and threshing machines don't have excessively high power requirements, and the (1-100 A) specification is a perfect match. On the pole under the transformer at the village entrance, rows of these simple, easy-to-understand drop fuse devices are almost all hanging there.
