The Thermal-Link (DC-ATCO)-DC Alloy Type is installed on the heater and connected
in series with the high-voltage heating circuit. When the heater is abnormally heated,
the temperature reaches the melting point of the Thermal-Link, which can cut off the
450 VDC circuit, and the heater stops working. The ceramic housing can withstand
500 ℃ temperature impact for a short time.
The Thermal-Link (DC-ATCO)-DC Alloy Type is installed on the side of the PTC heater.
Under normal conditions, the Thermal-Link remains connected. When the IGBT/MOS
breakdown, short circuit or other abnormality occurs, the heater continues to heat up,
the temperature exceeds the set value and reaches the melting point of the
Thermal-Link, the circuit is cut off and the heater stops working.
The Thermal-Link (DC-ATCO)-DC Alloy Type is installed on the side of the heating tube
and connected in series with the DC heating circuit. During the failure process of the
defroster, the temperature reaches the melting point of the Thermal-Link, the circuit is
cut off, and the heater stops working.
The Alloy Thermal-Link (ATCO) is installed between the heat sinks. During the fault
process, the temperature reaches the melting point of the Thermal-Link, which
physically cuts off the circuit to protect the equipment.
The speed regulating resistor is connected in series with the Organic Thermal-Link.
When the thermal element of Organic Thermal-Link senses the abnormal heat and
reaches its predetermined melting temperature, the thermal element strength
decreases due to melting, and the trip spring will separate the sliding contact, then
disconnect the circuit.
The DC-Alloy Thermal-Link (DC-ATCO) is used as the electrical connection at the cell
parallel point. When an over current occurs, the Thermal-Link can heat itself and fuse.
It meets the requirements of UN38.3 lithium batteries transportation. In the event of
partial overheating, the heat is transferred to DC-Alloy Thermal-Link(DC-ATCO), the
connection point can be passively cut off.
This special DC-Alloy Thermal-Link(DC-ATCO) has separated the temperature sensing
part and the current carrying part, which reduces the temperature rise difference
between current carrying part under different currents and ensures the operating
temperature accuracy of temperature sensing part. It is installed in the charging /
discharging circuit, close tight to the battery, and cut off the circuit when an
abnormal temperature rise of the battery occurs.
