Description
Technical field
The present invention relates to a kind of intelligent socket systems, belong to intelligent socket field, and in particular to a kind of jack system, this is
System includes monitoring modular, voltage control module, further includes alarm module if necessary, which has the intellectual monitoring mankind or dynamic
The distance between object and voltage control module voltage output unit, when this distance reaches the safe distance of default, prison
It surveys module and sends out instruction reduction output voltage to safe voltage or safe voltage or less to voltage control module.
Background technology
Socket, also known as power outlet, switch socket, translator of English:socket.Socket refer to there are one or more than one electricity
The pluggable seat of road wiring, can be inserted into various wiring by it.It is convenient for connecting with other circuits in this way.By circuit and copper piece it
Between connection and disconnection, to reach the connecting and disconnecting for being finally reached the partial circuit.In general, residential electricity consumption is alternating current voltage
220 volts, the three-phase alternating current piezoelectric voltage of commercial power is 380 volts.
Related data counts, and China is every year because death toll caused by industrial accident is about 130,000 people, wherein electrocution
The number of dying is about 8000 people, accounts for about 6 the percent of total death toll, is had greatly because contact socket is got an electric shock and died.
Human body can get an electric shock one must condition be：Human body becomes the part in current loop.Human body becomes electric current
A part in circuit, there are two types of forms altogether, and one is human bodies directly (to be exchanged with 220V with the electric shock form of electrical power contacts
For electricity), this electric shock form is divided into monopole contact and bipolar contact.When monopole contacts, when human contact's firewire with
The earth forms circuit.
Human body becomes second of form of current loop：Human body is not in direct contact the electric shock mode (high pressure) of power supply.One
Kind is step voltage, another is that electric arc gets an electric shock, and step voltage refers to：Enter into polar region electric current and puts bit distribution around place
Area is formed into a loop because of voltage difference between bipod with the earth.Electric arc gets an electric shock：For body close to high-tension apparatus, equipment discharge breakdown is empty
Gas makes human body as a part for current loop.
Safe voltage refers to that will not make one voltage that is directly lethal or disabling, allows continuous contact under the conditions of general environment
" Safety Extra Low Voltage " be 36V.Industry provides that safe voltage is not higher than 36V, and continuous contact safe voltage is 24V, safety
Electric current is 10mA, and the extent of injury to shock by electricity to human body depends primarily on the size and conduction time length by body current.
The characteristics of according to production and Work places, be to prevent electric shock injures and deaths thing using corresponding safe voltage
Therefore fundamental measure.National standard《Safe voltage》(GB3805-83) grade of regulation safety of China voltage rating is
42V, 36V, 24V, 12V and 6V, should according to Work places, operator's condition, occupation mode, power supply mode, line conditions etc. because
Element is selected.Such as the electric hand tool used in special hazard environment should use 42V extra low voltage；Have in shock hazard environment
The hand-held illuminating lamp and local lighting lamp used should use 36V or 24V extra low voltage；The spies such as in canister, especially at humidity
The hand-held illuminating lamp used in other hazardous environment just uses 12V extra low voltage；The places such as underwater operation should use 6V extra low voltage.
《Safe voltage》(GB3805-83) it is a most authoritative basic standard about the voltage that is safe from danger to people.Abundant analytical table
In data after it is found that under the conditions of least favorable (in addition to medical treatment and human body are submerged in water), this limit value is:15~100Hz
Alternating voltage (virtual value) is no more than 16v；Ripple-free direct current is 35v.Wherein 50Hz exchanges the numerical value of 16V, more now China's work
The 36V that journey custom (or even junior physics textbook) also uses is much low；The GB4706.1-98 of publication in more below 1998
(the safety general of household and similar applications electric appliance requirement》The Safety Extra Low Voltage of middle defined is no more than the numerical value of 42V.
