The impact of power outages on vending machines and emergency measures

A power outage means that the transmission of power is stopped, making the electrical appliances unable to obtain external power. It can include man-made power outages (such as maintenance of lines, peak-shifting power usage, power cuts, arrears of electricity bills, etc.), power outage protection (such as lightning protection, prevention of electrical overload, etc.), accidental power outages (such as man-made sabotage, bad weather, etc.) , Short circuit, accidental open circuit, etc.).　　Using vending machines on a daily basis, it is inevitable to encounter power outages. For televisions, computers and other electrical products, power outages will damage them, and frequent power outages may even cause malfunctions. So does power outage harm the vending machine? 　　 At present, commercial vending machines generally have refrigeration systems, most of which are compressor-type. Such vending machines save electricity and cool down quickly. When the refrigerant vaporizes in the evaporator, it absorbs heat and cools. The vaporized low-pressure refrigerant needs to be compressed into high-pressure, high-temperature steam by a compressor, and then reduced to liquid after being radiated by the condenser. This cyclic process mainly relies on the intermittent operation of the motor to achieve.　　Each time the motor starts, the vaporized refrigerant belongs to a light load, so it is easy to start. If the plug is unplugged while the compressor motor is running, and then the power is turned on again, the motor will face a heavy load of high-pressure refrigerant, and it will become very difficult to start, or even unable to start. At this time, the starting current through the motor will reach 10 times the normal value, which is very easy to cause the accident of burning the compressor motor. Since the pressure of the high-pressure refrigerant will naturally decrease after 3-5 minutes, plug in the plug again after 5 minutes to ensure that the motor will not be burned. Similarly, an instantaneous power outage from the power grid, which is immediately transmitted after a few seconds, is very harmful to the vending machine. Install an instant power-off protector for the vending machine. The input of the power-off protector is connected to 220 volts AC power, and its output is connected to the vending machine plug. When the power goes out instantly, the power-off protector will automatically extend the power outage by 5-8 minutes. , To meet and protect the requirements of vending machines. For vending machines that are not equipped with instant power-off protectors, the plugs, sockets, and power leads of the vending machines should be in good contact. When there are frequent instantaneous power outages in the power grid and there are engineering and maintenance areas for the power grid and the home power system, the use of vending machines should be temporarily stopped. Of course, the power grid department responsible for engineering and maintenance should notify users in advance.　　 It can be seen that a power outage will not do much harm to the vending machine, but the short-term power on after a power outage will cause great harm to the vending machine, so take precautions. Therefore, in the event of a power failure, unplug the power plug in time, confirm that the power is restored to normal, and then plug in the power for use.　　Emergency measures 　　In the event of a power outage, use flashlights and other lighting tools to first check whether the internal power distribution switch and leakage protector are tripped.　　 There is a burning smell, smoke, and discharge in the room. All power should be cut off immediately to avoid fire.　　 The fuse is blown and should be replaced in time, but copper, iron, or aluminum wire cannot be used instead.　　 There should be candles, flashlights and other emergency lighting sources in the room, and they should be placed in a fixed location.　　Aging wires can easily cause power outages, so they should be reported to the relevant department for replacement as soon as possible.　　 If it is found that the power outage is not caused by indoor reasons, you should contact the property management staff in time.　　Haloo vending machine-China's large-scale unmanned vending machine manufacturer, provides a cost-effective, full range of vending machines, to meet the needs of customers' personalized customization, and to create a brand new vending machine product.
