Three, Precautions for Maintenance and Repair: During the maintenance and repair of a medium-frequency induction furnace, it is essential to keep the generator room clean and strictly prohibit the stacking of flammable materials. Promptly repair the furnace lining that has excessive melting damage, avoiding the mixture of iron filings and ferric oxide during repairs to maintain the crucible's integrity.

Switching power supplies utilize modern power electronic technology to control the on-off time ratio of switching tubes, maintaining a stable output voltage. They are generally composed of Pulse Width Modulation (PWM) control ICs and MOSFETs. With the development and innovation of power electronics, switching power supply technology is also continuously evolving. Currently, switching power supplies, with their small size, lightweight, and efficiency, are widely used in almost all electronic devices, making them an indispensable power supply method for the rapid development of the modern electronics information industry.

Therefore, it has certain specific requirements for the human-machine interface. It demands high reliability, energy efficiency, durability, and compactness, but lower requirements for interface quality and dynamic response capabilities. Standard LCD displays are currently acceptable in terms of their ability to provide interfaces, agility, and power consumption. However, as a mouse for interface positioning, they generally lack reliability and seem cumbersome. As a result, we have a special fondness for "touchscreen technology" that allows direct hand positioning on the interface. It aligns perfectly with our human instincts and habits. Regarding how to achieve this positioning function—whether using variable resistance, variable capacitance, pressure-sensitive, or infrared types—the end-user can remain indifferent; simply enjoying the benefits is sufficient.

Therefore, if the leakage equipment's housing is electrified, touching it can cause an electric shock. The circuit breaker will trip just as it would if the current through the human body exceeds the leakage current trip level (usually 30mA), but it poses a danger to the person. Moreover, when the equipment leaks, some current will flow through the housing to the ground wire. At this point, the line and neutral currents in the zero-sequence current transformer are unequal, and when their difference reaches the leakage current trip level, the circuit breaker will trip. In summary, whether the circuit breaker trips is greatly related to whether the housing is grounded. Ground wires should not be directly tied to metal water pipes or gas pipes; they must be reliably grounded. In principle, the smaller the grounding resistance, the better, and a grounding resistance of 4Ω or less is sufficient to meet the standard.

You need a thermometer with a resolution of 0.1 degrees. The terms "digit" and "character" are used to describe the resolution of a multimeter. They can be grouped by the number of digits or characters displayed on a digital multimeter. A 3-digit multimeter can display three full digits (0-9) and one "quarter digit" (either showing a "1" or left blank). A 3-digit multimeter's display resolution is up to 1,999 characters. A 4-digit multimeter's display resolution is as high as 19,999 characters. Compared to "digits," using "characters" provides a more precise description of the multimeter's resolution. The resolution of today's 3-digit multimeters can be as high as 3,200, 4,000, or 6,000 characters.
