Water Cooling Alarm System
Sep 26,2020
Water cooling system It is the most important auxiliary system for the medium-frequency furnace, and is generally divided into a furnace cooling system and an electrical cabinet cooling system. Medium-frequency furnace body The coil is wound from square copper tubing. Although copper has a low resistivity, the current flowing through it is very high. Due to the skin effect, the current within the copper tubing tends to concentrate toward the wall of the crucible, causing significant heat generation in the tubing (thus, the insulating varnish used on the surface of the copper tubing must possess high-temperature resistance). To ensure proper insulation of the furnace coil and the safety of the molten pool, sufficient cooling capacity must be maintained during melting. The cooling system must not be stopped until the crucible temperature drops below 100°C. The cooling section of the electrical cabinet is primarily designed to cool thyristors, capacitors, inductors, and copper busbars, all of which generate substantial amounts of heat during operation.
The common medium-frequency furnace water cooling alarm system mainly includes:
(1) Water temperature, pressure, and flow meters installed on the inlet pipeline monitor the inlet parameters of the water cooling system. When the water temperature exceeds the setpoint, the cooling tower’s power output should automatically increase. If the temperature surpasses the alarm threshold or the pressure and flow fall below the minimum allowable levels, an alarm should be triggered and the power supply should be cut off.
② Temperature sensors are installed in series at the outlets of the cooling water pipes for both the furnace body and the electrical cabinet. These sensors require manual reset. During maintenance, the reset button on the temperature sensors can be used to quickly pinpoint the location of any abnormalities.
