The safe operating point of induction heating furnace

The safe operating point of induction heating furnace

1, high frequency, intermediate frequency and power frequency induction heating operation, should pay special attention to prevent to get an electric shock. Before work, the operator should wear protective equipment of the insulation, the preparation of the floor should be laid rubber pad, and pay attention to prevent leaking cooling water spilled on the floor and other places.
2, equipment internal insulation must be good, reliable grounding, equipment should be installed protective fence around, after being closed high voltage switch, no one shall be within the scope of the dangerous activities. Preparation to bright light, install exhaust equipment, keep ventilated, indoor temperature control in 18-35 ℃.
3, before starting the equipment must be cooling water, the water pressure is 1.2 ~ 2 ATM ATM (1 = 0.1 MPa). Sensors in the load artifacts, all closed the door of the cabinet.
4, according to operation procedure, comply with the provisions of the filament preheating preheating time; When heated to maintain the current bias for screen flow (Yang) value of 15% one 20%, in order to make the oscillator output efficiency is highest; Circuit of the condenser cooling water outlet temperature should be below 35 ℃, the cooling system should be less than 55 ℃, stop working after about 10 ~ 15 min to stop water supply.
5, high-frequency equipment will produce radiofrequency radiation effect, after more than a certain amount, can produce adverse effect on the human body, the radiation source of reason to the equipment such as high frequency transformer, coupling capacitor and inductor shielding measures should be taken to prevent the high frequency electromagnetic leakage. Should guarantee the working environment of the radiation intensity control within the prescribed scope (electric field intensity E 20 v/m or less, magnetic field intensity H 5 a/m or less).
6, regular replacement of capacitor in the transformer oil, the longest do not exceed half a year, and check whether "band" in good contact.
7, the use of 200 ~ 300 h after to wash the oscillation tube anode with 10% hydrochloric acid solution on the scale, until clean (but not with a knife); Then rinse with warm water, and assembly.
8, the equipment should be kept clean, dry, of the anomalous phenomenon occurred shall be immediately cut off the power supply, check and troubleshoot rear can continue to work. High frequency equipment should be the specialist is responsible for the maintenance, the maintenance should be first discharge, then maintenance, to ensure personal safety.
