1 T medium frequency heating furnace perfect protection and operation monitoring system

Through the cooling temperature exceeds the set value and power off. The capacitors are monitored using pressure and temperature sensor devices that alert and shut off the power supply once the capacitor leaks or the temperature is too high.

    The 1T intermediate frequency heating furnace has a water pressure relay control for the power supply cooling water input, and the cooling water output has a temperature switch table to monitor the undervoltage, and the over temperature will issue an alarm and cut off the power supply.   '

    The 1T intermediate frequency heating furnace is equipped with an output voltage meter, an output power meter, a working frequency meter, an input current meter, an input voltmeter, a DC voltmeter, a DC current meter, a phase loss display on the control panel, and an inverter operation display. The two furnaces can display the intermediate frequency voltage, power and operating frequency respectively. A circuit breaker is installed in the electrical control cabinet, which is a disconnection point for the power inlet disconnecting switch and the knife gate, and has short circuit protection, ground trip protection and phase loss protection, fuses, and the like. The electrical cabinet door is interlocked with the power-off line, and the main power source is cut off when the electrical cabinet door is opened. The original design of the electrical equipment is reasonable, the discharge is neat, the repair and replacement of parts are convenient and fast, and all the large heating elements and copper bars are set with reasonable water cooling as needed. Set up a completed protection system, such as: use the sensor to take the line current, voltage, channel current toxic voltage to take signals, to the double-closed digital circuit for current limiting, voltage limiting, over-current and over-voltage repeated protection, water temperature, water pressure Protection and so on. KK thyristors, l (P thyristors have self-shutdown time protection.
