Microcomputer protection device in the field of electricity can help us do

1, over-voltage protection
Overvoltage is fatal to any project, and it may make irreparable damage to all equipment. Specifically refers to any voltage whose peak is greater than the response peak of the maximum stable voltage in the normal state. In general terms, the lightning when the rain, the nuclear explosion in the test and the usual switching operations are the main source, and the computer protection device can system to protect it.
2, non-power protection
This term refers to the fault is not reflected by the electrical action or the transmission of the protection, power, including voltage, current, resistance and frequency parameters, non-power refers to the pressure, the temperature level, the fire probe information Power independent parameters. Microcomputer protection device can record and protect non-power data, for the time to run out of control parameters, to choose their own non-power lock, that is, automatic gate.
3, overheating protection
This effect is more simple and easy. The current through the line or the relay will lead to the heat of the distribution, this time due to the characteristics of the metal heat caused by expansion, the relay in the bimetallic film will be different because of the thermal expansion coefficient of bending deformation, to a certain extent, the relay will be broken because So that the line crashes, microcomputer protection device can be closely monitored to prevent such a situation.
