Question Q/A:
1. In, Imax, Un, Us.max, Up, what is the Uc meaning?
In is the fixed discharging current, this is when the damage electricity welling up may pass 20 time (for 8,/20 microsecond) magnitude of current.
Imax is the biggest discharging current, electricity welling up only can pass 1 time (for 8,/20 microsecond) the magnitude of current. Imax is bigger than In.
Un is the low pressure power distribution network fixed working voltage.
Us.max is the low pressure power distribution network highest running voltage.
Up refers when the fixed discharging current, the protection end remnant pressure level, namely the instant inlays the position voltage the immobilization ability. When Up exerts Yu Dianyong, the electricity welling up movement makes very big flows rapidly In rapidly through after to restore normally, thus gets up the protective function.
Uc is most greatly continues the running voltage, can add in the electricity welling up beginnings and ends cannot direct 起电 the welling up characteristic change and strike exactly protects the part the greatest voltage.
Whichhow many big kind of products does 2. Towle electricity company electricity well up the protector to divide into?
Altogether divides into five big kind of products:
Has the TRS power source electricity to well up the protector, the TRSS signal electricity wells up protector, the TRSW day feed wells up the protector, the TRSBT lightning rod series, the TRSX power source anti-radar box
3.choices electricity well up when the protector should consider, which factors unify?
Is protected the load the characteristic
The scene environment characteristic (has lightning rod system/non- lightning rod system)
Earth system type (TN-S, TN-C-S, TT)
Howdo 4. electricity well up the protector operating performance condition to demonstrate?
The power source electricity wells up the protector: The frontage has the LED instruction window, the green is normal for the active status, red expressed electricity welling up must give to replace.
Which standards does 5. Towle electricity company's electricity well up the protector to conform to and to examine through which?
The Towle electricity company product obtains the sales permit which issues by People's Republic of China Ministry of Public Security, the Beijing anti-radar center examination report and so on.
QX/T10-2002 "People's Republic of China Meteorology Profession Electricity Wells up Protector Standard"

IEC61643-21 "Telecommunication Equipment Surge Protector"
IEC61024-1 "Building Anti-radar Design Standard"
IEC61312-1 "Thunder and lightning Electromagnetic pulse Protection"
IEC529: 1,989 "Outer covering Protection Rank" and so on.
6. Towle electricity company produces how many levels of protections does the power source electricity well up the protector to divide into?
Divides into three ranks: B level, C level, D level
B level protection greatly to 100KA, C level protection greatly to 65KA, D level protection greatly to 40KA.
How 7. guards against the mine field is divides?
Guards against the mine field mainly to follow following principle division:
LPZ0A area: In home court each kind of object all possibly encounters directly is struck by lightning and leads completely is struck by lightning the electric current, the electromagnetic field has not obtained any weaken, is undefended area which completely exposes.
LPZ0B area: In home court each kind of object is impossible to encounter is bigger than chooses grounder the radius correspondence thunder and lightning to flow directly is struck by lightning, the electromagnetic field has not obtained any weaken, is the full exposition straight to strike the thunder zone of protection.
LPZ01 area: In home court each kind of object is impossible to encounter directly is struck by lightning, flows after various conductors electric current, is smaller than the LPZ0B area; In the home court electromagnetic field intensity possibly weakens, this is decided by the shield measure.
LPZn+1 following guards against the mine field: When needs further to reduce the electromagnetism field intensity degree-hour, should additionally build following guards against the mine field, and following defers to the environment area choice which the protection object requests to guard against the mine field the request condition.
Why 8. has to use electricity wells up the protector?
Thunder and lightning destructive power enormous exterior, depends on anti-radar (lightning rod and so on) is only insufficient, the thunder electric wave can direct or is indirect (through electromagnetic induction) invades various electrical circuit and the metal channel (for example power line, holding wire, day feed line and metal pipeline and so on). From this the thunder and lightning which produces overvoltageand the electricity wells up the voltage to electronic, the electrical equipment, the information network system has the very big harm, lightly destroys the line, the heavy piece of damage equipment, causes the system paralysis, causes losses which estimates with difficulty.
The rapid change thunder electric current, can and in the twin conductor induces in the electrical ring circuit has the high voltage to cause the system the insulation to destroy. Electrical power system each kind of operation can have on the power circuit switching surge; Some electric appliance equipment switch operations, short-circuits trips and so on to be able to produce in the power source line is higher than the normal work voltage overvoltage (surge voltage) thus to have the harm to the current collector.
9th, how selects the appropriate power source arrester:
In a local choice protection different type equipment arrester, should synthesize the consideration following factor:
This local thunderstorm intensity Ng as well as the biggest discharging current occurs probability P
By protection device tolerance impact level
(Should decide by the protection device value according to state economy level)
By protection device social importance
Determination different protection voltage UP and discharging current power source arrester
