Dc fuse is a very easy to use protection facilities, when the abnormal circuit is often accompanied by rising current, the rising current will not only damage some key equipment, but also burn the circuit, cause a fire and directly cause great economic losses. After the DC fuse is installed, when the current exceeds the current value that the DC fuse can bear, the DC fuse will melt and break itself because of the heat generated by the excessive current, killing the danger in the bud and fully protecting the line from damage.
The internal structure of DC fuse is metal with low melting point. The whole parts are installed in series in the circuit. When the current in the circuit exceeds its rated value, it will be fused because of its own heating. Dc fuses have simple internal structure, convenient installation and obvious effect. They are widely used in various power systems and power facilities. Dc fuses are also installed in many people’s homes to protect home appliances from sudden damage.
1. Check whether the solar panelsare damaged or not, and find and replace them in time.2. Check whether the connection wires and ground wires of the solar panelsare in good contact.3. Check whether there is any heat phenomenon at the wiring of the combiner boxes.4. Check whether the battery board bracket is loose or broken.5. Check and […]
Are you worried about your electronic devices getting fried due to voltage spikes? Well, worry no more! We have the answer for you – the surge protective device. A surge protective device, or SPD, is a device that is designed to protect electrical equipment from voltage spikes or surges. These spikes can be caused by […]
ommon mode SPD between phase and PE or phase and PEN is installed whatever type of system earthing arrangement (see Fig. 1). The neutral earthing resistor R1 used for the pylons has a lower resistance than the earthing resistor R2 used for the installation. The lightning current will flow through circuit ABCD to earth via […]
