1、附录 A 1, lighting switches why we need to follow on the front lines? If the lighting switch is installed in line, although Electric disconnected when not lit up, but the phase diad line is connected, And when people think that the lights are not bright, will mistakenly believe that the state is in po
2、wer outages. In fact lamps at various points to the right voltage is 220 volts of dangerous voltage. If the lights at the destruction of these people actually live touched the site, which will result in electrocution accident. Therefore, various lighting switches or small capacity single-phase power
3、 switching equipment, only rods on the front lines in order to ensure safety. 2, single-phase three-hole sockets how to install the correct? Why? Typically, single-phase power equipment, in particular mobile electronic equipment, should use three core plugs and matching three-hole sockets. Taking th
4、e outlet dedicated to the protection of a zero (to) jack, with the introduction of zero protection, It was often the only outlet end of this hole inside wiring socket head with the introduction of the zero line Aucknagen directly connected, This is extremely dangerous. Because if the power line is d
5、isconnected, or the fire power (equivalent) lines connected to the anti-zero. its shell and other metal parts with the power to bring the same voltage, which could lead to electric shock. Therefore, the wiring should be dedicated grounding jack dedicated to the protection and grounding line connecte
6、d. Using zero protection, zero-power lines should lead to specialized, and not the nearest outlet to introduce the use of zero line. 3, plastic insulated wire why no direct buried in the walls? (1) plastic wire insulation prolonged use, the aging of plastics will be fragmented, greatly reduce the le
7、vel of insulation, When the short circuit overload or short circuit, the more insulation accelerated the damage. (2) Once the wall wet, it will trigger large-scale leakage and endanger their personal safety. (3) plastic wire insulation directly Buried and is not conducive to line maintenance and upk
8、eep. 4, why should the use of leakage protection devices? Leakage protection devices known as leakage protection switches, is a new type of electrical safety devices, and its main purpose is : (1) to prevent electrical equipment and electrical lines caused by the leakage of electric shock accident.
9、(2) Prevention of electricity in the process of single-phase electric shock accident. (3) promptly cut off electrical equipment operation of the single-phase fault, and prevent electrical leakage caused by the fire accident. (4) With the improvement of peoples living, household appliances continues
10、to increase, in the course of electricity, Electrical equipment itself because of the defect, the use of inappropriate technology and security measures resulting from the adverse physical electric shock and fire incidents, to the peoples life and property caused undue loss and leakage protection for
11、 the emergence of prevention of various types of incidents, promptly cut off the power supply, protective equipment and personal security, providing a reliable and effective technological means. 5, the electric shock accident occurred What is the main reason? Statistics show that the electric shock
12、accident occurred attributed the following : (1) lack of knowledge of electrical safety. Controls in the vicinity of kite flying, climbed onto the high voltage poles dig nests； Low-voltage overhead line break after the blackout hand QushiFireWire； Charged night Connection hand touch Charged； touch p
13、lastic cover damaged switch. (2) a breach of rules to live connecting lines or electrical equipment have yet to take the necessary security measures； touched on the destruction of equipment or cable； Teng mistakenly charged equipment； Charged then lighting； Charged repair electrical tools； Live mobi
14、le electrical equipment； shake hands with wet bulbs. (3) Equipment failure, inadequate safety distance； Second-line system to a grounding resistance too； Grounding line failure or grounding line disconnected； exposed wire insulation damage, such as outside. (4) equipment in disrepair, gales bi lines
15、 or poles felled not repaired in a timely manner； Switch plastic cover damage to the bakelite not timely changes； damaged electrical wire, long live the shell； Insulator damage, but has shorter lines and cable access, equipment enclosures charged. (5) other accidental causes, the night running conti
16、nuously on the ground to touch the live wire. 6, electrocution occurred when the ambulance take measures? Electric shock accident occurred when the ambulance ensure their own safety, we must first try to make speedy electric shock from power, then proceed to the following repair work. (1) undo preve
17、nt electrocutions were breathing a strait jacket services. (2) Inspect the oral electric shock, clearing the oral mucous, if dentures, then removed. (3) the spot immediately for emergency treatment, such as the cessation of breathing using mouth-to-mouth resuscitation method where If the heart stopp
18、ed beating or irregular fibrillation, artificial Thoracic extrusion rescue. Never without undue interruption. If the scene in addition to ambulance, there is the presence of the second person, it should immediately following work : 1) to provide emergency use of tools and equipment. 2) discouraging
19、people from the scene miscellaneous people. 3) Keep the scene have sufficient lighting and ventilation is good. 4) report to the leadership and ask the doctor to come to the rescue. Experimental research and statistics show that from an electric shock minutes after treatment, 90% can be saved； If th
20、e electric shock from six minutes after the rescue began, only 10% of save opportunities； From electric shock 12 minutes after the rescue, it is very unlikely to save. Therefore, when it was found that electric shock, should the same thing, using all possible means. 7, home safety measures which have electricity? Along with the popularization of household appliances, correctly grasp the knowledge of the safe use of electricity to ensure that electricity security.
