On the seventh day of the first lunar month, the whole hospital resumed normal work, and Warren received a big red envelope for the New Year, with 300 yuan, so happy that she almost hugged Director Zhang and kissed her: "Master, you are really my God of Wealth!"

The red envelope was received by Director Zhang from the finance department, and all the staff of the hospital went to work, plus the retired old workers, there were too many people, and it was impossible for the leaders of the hospital to send them to everyone one by one, so let each department send a representative to get it back.

Xiao Yang teased Wo Lin: "That's all you need, when you become an official, the red envelope will be bigger than this." ”

"How big?" Warlene stared at the red envelope in Director Zhang's hand.

"It's that big. Director Zhang took out the money in his red envelope, four hundred yuan, one hundred more than Volin's.

Warlene sighed: "Master, when you are the director, you are only a little more than my New Year's money?"

"The leaders of the hospital are only a little more than mine, how much more do you expect from me?" Director Zhang stuffed the money back into the red envelope.

He hit Warlene: "Don't just be happy, most of the instruments have been off for seven days, and today is the first day to turn on, it is very likely that there will be a large number of problems, you have to be mentally prepared to work overtime on the first day of work." ”

Warlene didn't believe it: "Master, just scare me, how can you say so evil." ”

Warlene has heard that most people avoid medical treatment during the first month, and if they can persevere, they will not enter the hospital on the fifteenth day of the first month.

Xiao Yang, who had just received a phone call, replied for Director Zhang: "Don't believe it, it's so evil, it's still a big evil, and the radiology department called and said that there was a problem with the filming machine." ”

The diagnosis of many diseases depends on the filming machine, and if the filming machine is broken, it is really a big problem.

Warlene was stunned for a moment, and reacted: "The film machine is turned on every day, and there are still people on duty at night, how can there be anything like the master said that the camera has not been turned on for seven days, Sister Yang, you tease me." ”

"Haha, isn't she just kidding you? Master Cao made fun, "The power went out just now, it is estimated that the film machine is broken for this reason, Xiao Wo, you remember, if the hospital suddenly loses power without warning, there is a high chance that the instrument will have a problem." ”

This Warlene understands that when the power is suddenly cut off, the electrical appliance is hit by abnormal current and voltage, and the electrical appliance is easily damaged.

For electrical appliances, power-on and power-off are both "transition processes", and it is easy to overcurrent when powering on, and overvoltage when powering off.

Some electrical appliances are programmed to control, and sudden power-off during program operation is not good for the equipment; some equipment has a "chain" control relationship in operation, and there must be a sequence of opening and shutting down, and sudden power-off is not good for the equipment.

For example, lightning strikes, short circuits, excessive line load, etc., due to the sudden appearance of excessive current in the line, resulting in the tripping of switchgear, before the switchgear trips, sometimes excessive current has entered the electrical equipment through the switch, resulting in damage to the electrical equipment.

Sudden power failure will produce a strong electromagnetic interference pulse, this interference pulse into some highly sensitive preamp parts, will overload the operational amplifier and damage, most electrical appliances are inductive loads, power off moments, due to the induced electromotive force will be superimposed with the power supply and make the insulation breakdown, components overvoltage and burn out.

A sudden power failure will cause damage to the equipment, but turning off the power will not cause damage, that is, when the power is turned off, the equipment itself "executes" the shutdown action or program, so some equipment is directly controlled by the power on/off, and the sudden power failure can only make it stop working, and will not adversely affect the equipment,
