Protector of leakage of electricity is the electric equipment of relatively common a kind of protection in industrial and mining enterprises and family, use in holding dynamoelectric tool especially relatively general, but, go up as a result of understanding of the person that use have mix by accident use incorrect, make the protective effect that protector of leakage of electricity has less than answering to have in be used actually. Existence problem has: One, type selecting impropriety, the protector of leakage of electricity that is used at preventing to get an electric shock should choose tall sensitivity fast model, the product of its movement electric current and behavioral time should not exceed 30mAs. 2, understanding has by accident, mistake of the person that some use moved a tool to install protector of leakage of electricity to hold phone with respect to all things encyclopedia, omited receive 0 protection, make protected electric equipment to lose leakage of electricity to protect action, rose to get an electric shock only protective action. 3, use non-standard, 0 lines of 0 lines and job are protected to did not part in protector of single-phase leakage of electricity, leakage of electricity protects functional invalidation, once tool crust leakage of electricity, short-circuit current is returned protector of burn down leakage of electricity; Perhaps protect 0 lines and job although 0 lines parted, but in power source electrical outlet ground wire is carried impending, it is false ground connection actually, make leakage of electricity protects the protective effect that still has less than answering to have. Protector of leakage of electricity uses an occasion 1, must install protector of leakage of electricity (switch of leakage of electricity) equipment and place: (1) belongs to I kind movable type is electric equipment and hand-held are dynamoelectric tool (I kind electric product, namely the prevents electrical shock protection to rely on equipment not only basic insulation of the product, and still include additional safe precautionary measures, like product crust ground connection) ; (2) installation is in damp, strong caustic the electric equipment that waits for abominable place; (3) builds the facility of electric construction machinery of construction building site; (4) of short duration sets the wiring that uses phone temporarily; (The electrical outlet inside the guest room of 5) guesthouse, restaurant and hostel loop; (The electrical outlet inside the building such as 6) mechanism, school, enterprise, residence loop; (Equipment of the lighting in the water of 7) swimming-pool, fountain, piscina; (8) installs circuitry of underwater power supply and equipment; (What human body contacts directly in 9) hospital is electric and medical equipment; (10) other needs to install the place of protector of leakage of electricity. 2, call the police the application of protector of type leakage of electricity: When once produce dump of leakage of electricity,be opposite, can create the electric unit of accident or significant pecuniary loss or place, should install call the police protector of type leakage of electricity, be like: (The passageway illume with public 1) , lash-up illume; (2) fire control is reached with elevator ensure the equipment of public safety; (3) is used at the power source of fire control equipment, wait like illume of passageway of water pump of fire alarm device, fire control, fire control; (4) is used at the power source that guard against theft calls the police; (5) other does not allow the special device of power cut and room. 3, outside installing regulations except the electric equipment that should abide by convention, still should notice the following: 1.

The installation of protector of leakage of electricity should accord with the requirement of manual of manufacturer home product. 2.

The protector of leakage of electricity that mark has power source side and bear side must not be received instead. If receive,turn over, meet those who bring about protector of electronic type leakage of electricity take off buckle coil to cut off and cannot cut off the power along with power source, as a result is long electrify and burn down. 3.

Protector of installation leakage of electricity must not be demolished or forgo original safe preventive measure, protector of leakage of electricity can defend as electric safety only the add safeguard in the system. 4.

When installing protector of leakage of electricity, must distinguish strictly neuter line and protective route. Use triode 4 lines type and 4 extremely when protector of leakage of electricity of 4 lines type, neuter line should receive protector of leakage of electricity. The neuter line that passes protector of leakage of electricity must not regard protection as the line. 5.

The job 0 lines must not emphasize particularly on in bear of protector of leakage of electricity answer ground connection, otherwise protector of leakage of electricity cannot work normally. 6.

Use the spur track of protector of leakage of electricity, its work the 0 lines that 0 lines can regard this loop as only, prohibit working with other return circuit 0 lines are linked together, the job that other line or equipment also cannot use the circuitry after already using protector of leakage of electricity or device 0 lines. 7.

After installation is finished, should according to " build quality of electrician Cheng construction to check and accept a standard (GB50303-2002) 3.

1.

6 clauses, namely " the protector of leakage of electricity of motivation and gaffer Cheng should do imitate movement to experiment " requirement, have a test to protector of finishing leakage of electricity, in order to assure its sensitivity and dependability. Experiment pushbutton can be operated 3 times when the experiment, take bear cent to close 3 times, affirm the movement is not had correctly by accident, type investment uses Fang Kezheng. 4, the safety of protector of brief summary leakage of electricity runs the administrative system that should rely on an effective and measure to assure. Besides doing good periodic to safeguard, still should be opposite regularly the movement of protector of leakage of electricity is characteristic (include cost of action of leakage of electricity and behavioral time, leakage of electricity not value of behavioral electric current) have a test, had done detect record, compare with the numeric photograph when installation is initiative, judge its quality to whether have change. In use should use protector of leakage of electricity according to the requirement of operation instruction handbook, check every months by the regulation, operate the experiment pushbutton of protector of leakage of electricity namely, check its to whether can disconnect normally power source. The time that should notice to operate experiment pushbutton when the examination cannot too long, it is advisable to be moved in order to nod commonly, frequency also cannot too much, lest burn down is in-house component. In use of protector of leakage of electricity produces tripping operation, when discovering switch movement reason via the examination, allow to try power transmission, if again tripping operation, should prove a cause, find out breakdown, must not successive forcibly power transmission. Protector of leakage of electricity once when attaint cannot be used, answer to ask major to electrician undertakes checking or change instantly. If protector of leakage of electricity produces misoperation and refus action, its reason is by protector of leakage of electricity itself is caused on one hand, it is the cause that comes from circuit on the other hand, should seriously concrete analysis, privately disassembles and do not adjust the in-house parts of an apparatus of protector of leakage of electricity.
