Description
Technical field
The utility model belongs to electronic technology field, relates to a kind of hotel standard room " card insert type " electricity-saving controller.
Background technology
Plug-in card electricity-getting switch (electricity-saving controller) is that special energy-conservation and safety for hotel, hotel designs, after the plug-in card electricity-getting switch is installed in the hotel, when the guest moves in, the guest inserts door card (card opens the door) electricity-getting switch of reveal in the guest room, civil power in the guest room is connected, and the various electric equipments in the room (illumination, TV, air-conditioning etc.) can use; When the guest withdraws from a room, the guest takes the power taking card smoothly away, and (guest can withdraw from a room after must pulling out card, because also will open the door when the guest goes back to the room with this card), the general delay of plug-in card electricity-getting switch cuts off the power supply after 15～30 seconds automatically, realized purpose of saving and Electrical Safety.
The economize on electricity Economic and Efficiency Analysis of plug-in card electricity-getting switch
Electrical arrangement according to the hotel standard room: TV 120W, desk lamp 25～40W, left and right sides bedside lamp 25～40W * 2, Mirror front lamp 20W, standard lamp 25～40W, split-type air conditioner 1300W (on average by 1000W) establishes water tumbler 1500W (on average by 50W) by cable, the illumination of toilet, ventilating fan, hot hair dryer 1200W (on average by 60W) etc. are by 120W, and every standard room electrical appliance gross power on average is about: 1600W.After using plug-in card power taking control switch, calculate by average power 1600W, the electricity charge are saved approximately in annual every guest room: 860 yuan of 1600W/ every * 1.5 hours/every day * 1.2 yuan/every degree * 300 day/annual ≈.
If the electrical appliance that the guest does not close in the guest room is just gone out, the hotel waiter does not find in time that again the guest goes out, high-power electric appliance long-term work in the room might cause electrical equipment heating itself, or reduces with electrical safety performance or because of the overheated power consumption equipment that burns out, even initiation fire.In the guest room, install and the correct plug-in card electricity-getting switch that uses, just can solve safety utilization of electric power and economize on electricity problem in the hotel room effectively!
Install, use the plug-in card electricity-getting switch in the guest room, when the guest withdraws from a room, take the card that opens the door away, electricity-getting switch postpones to cut off automatically after 15～20 seconds the power supply in the guest room, so both saved a large sum of electricity charge to the hotel, prolong the useful life of guest room electrical appliance again, the more important thing is the coefficient of safety that has improved the guest room electricity consumption, met the development trend of current energy-conserving and environment-protective.
What the city's electrical power switching device that uses in the relatively more universal in the market plug-in card power taking control switch almost all adopted is the electromagnetic relay structure, there is the contact ablation of striking sparks easily because of electromagnetic relay is congenital, and the ablation of relay contact can constantly accumulate and increase conducting resistance, and then constantly aggravate the sparking of contact, thereby may cause economize on electricity not become, become the disaster hidden-trouble in the guest room on the contrary.
