Abstract ： There are many casualties caused by electric shock in China every year , Most accidents occur in electrical equipment and distribution devices . In an electrical accident , Unforeseen and irresistible accidents are relatively rare , A large number of electric accidents can be prevented by practical measures . This paper combines the characteristics of buildings for the elderly and the functions of intelligent safe power distribution devices , This paper expounds the methods of preventing electric shock accidents in buildings for the elderly .

key word ： Electrical accident ; Buildings for the elderly ; Intelligent safe power distribution device

summary

Is expected to 2025 year , In our country 60 Older people will reach 3 Billion , The proportion is 21%,65 The proportion of people over the age of will also reach 13.7%, Approaching an aging society . Our country will be in 2027 In, we entered an aging society , That is to say 65 The proportion of old people over years old is higher than 15%. In order to meet the needs of aging social population structure , Many old people's buildings have been built in China , As an apartment house for the elderly , It needs to conform to the characteristics of the elderly , Apartments for the elderly need to allow the elderly to use lamps safely 、 Air conditioning and other electrical equipment .

Power distribution design of senior apartment

load

Apartments for the elderly are generally composed of living rooms and bedrooms with independent bathrooms , The number of residents is 1~2 people . Electrical appliances generally include energy-saving lamps 、 The computer / The TV 、 Fan 、 Air conditioner 、 Water heater, etc . The power consumption is as follows ：

Distribution system

Each room of the apartment for the elderly shall be equipped with a distribution box and provided with leakage protection , Thus, it can not only meet the large load and special requirements of the elderly apartments, but also facilitate the safety management of electricity consumption . According to the 《 Design standards for residential buildings for the elderly 》GB/T50340-2003 The first 5.3.7 Stipulated in article , The living room and bedroom shall adopt safe power sockets , The height of the socket from the ground shall be 0.6-0.8m, To prevent water from splashing into the socket in the kitchen and bathroom , In addition to the use of splash proof sockets , It should also be higher than the ground 2.1m, The socket of wall mounted air conditioner shall be away from the ground 2.1m. As each floor of the apartment for the elderly is equipped with a centralized electricity meter box for metering , In order to count and manage the electricity consumption of apartments for the elderly , The data can be transferred to the computer background through the bus , In order to achieve the goal of saving electricity , Acoustooptic switches are used to control the lighting of staircases and corridors .

Electrical accident prevention measures

We want to reduce the frequency of electrical accidents in buildings for the elderly and the losses after accidents , There are two ways to start ：

（1） Prevent and avoid from the source ： Select high-quality equipment 、 Check the switch regularly 、 It is forbidden to pull wires without permission .

（2） Responding country “ Double prevention and double control ” Our security concept , Use smart devices to escort .

Encore AISD Series intelligent safe power distribution device

Introduce

AISD Series intelligent and safe power distribution device is an intelligent and safe power product specially developed by ankerui Electric Co., Ltd. for low-voltage power distribution side , This product is mainly aimed at personal electric shock safety accidents at low-voltage distribution side 、 Line aging 、 Electric leakage causes electrical fire and other common hidden dangers .

Products are mainly used in schools 、 The hospital 、 The nursing home 、 Rehabilitation center 、 The hotel 、 The mall 、 enterprises and institutions 、 Household appliances and other low-voltage occasions .

Functional characteristics

（1） Power supply stability . Single phase grounding fault occurs at the load end , Device alarm , However, the system does not need to cut off the power supply , Still sustainable power supply .

（2） Power supply security . The device can limit the leakage current of the system to a very small level , The human body accidentally touches the power supply line , No electric shock .

（3） Current limiting arc extinguishing . The system has a short circuit fault , The device can quickly cut off the power supply , No arc sparks .

（4） Overload protection . The device detects that the system is overloaded , You can cut off the power supply in time , Avoid deterioration of the fault .

（5） Voltage monitoring . The device monitors the system voltage in real time , When the line is under voltage , Give an alarm signal , You can set whether to cut off the power .

（6） Alarm function . Short circuit occurs in the system 、 overload 、 Under voltage and other abnormalities , The device sends out audible and visual alarm signals , Remind relevant personnel .

（7） Incident records . Device storage 20 Event records , It can be inquired by users .

（8） Communication function . Device configuration RS485 communication interface ,MODBUS-RTU agreement , The relevant data can be read remotely .

Technical indicators

Typical application diagram

AISD Series of intelligent safe power distribution devices can be connected to the electrical fire monitoring host through wired communication , You can also access the secure power management cloud platform or other cloud platforms through wireless communication , It is convenient for managers to maintain all elderly care places equipped with intelligent and safe power distribution devices , management .
