Protection function and principle



3.1 phase over- current protection



Device in the implementation of the three-stage cross-flow discriminant is logically consistent and


its operation conditions are as follows:


1) Iφ> Idn; Idn


is the current setting of the n segment



is phase current;


2) T> Tdn; Tdn is the delaying value of the n segment .


Its


low


pressure


blocking


element


and


negative


sequence


voltage


blocking


element


is


decided


according to controlling word .


3.1.1 Low voltage lockout element



Action


when


any


one


of


the


low


voltage


components


in


the


three


line


voltage


below


the


low


voltage setpoint, the open latch protection element. Using this component, you can guarantee that


the device does not appear in the case of non-fault motor feedback malfunction.


3.1.2 Negative sequence overvoltage lockout components



When


negative


sequence


greater


than


the


negative


sequence


overvoltage


setting,


open


lockout


protection components. Together constitute the the composite voltage blocking element, with low


voltage blocking element with over- current elements constitute the composite voltage over-current


protection.

The


device


provides


the


common


characteristics


of


the


three


types


of


inverse


time,


that


is


the


standard


inverse,


very


inverse,


extremely

setting


the


value of the corresponding inverse time index tuning. Inverse time characteristics of the following

Inverse time the value of the portion of the tuning for the value of the product of the molecules in


the above expression, in seconds, the tuning range is from 0.005 to 127.


It also applies to Inverse time for a long time . Long time inverse expression is as follows:

Phase-to-phase current protection device can be controlled by setting the relevant bit of the word


select definite time or inverse time. When the the select inverse time, automatically exit definite


time over- current paragraph III protection, section III of the phase current function plates inverse


time function of the phase current .



3.2 overload element



Overload element monitoring a three-phase current, and its operating condition:



The the MAX (Iφ)> Ifh, which for the overload current setting Ifh.



By the corresponding control word is set to alarm or trip.



3.3 zero sequence over-current protection



Device provides each of the three sections of the high and low side zero sequence over-current


protection, in which the high-pressure side of the zero-sequence III segment control word is set to


alarm when the high-pressure side of the zero-sequence current as a trip or alarm, zero-sequence

element with phase current.



3.4 Zero sequence overvoltage protection



Zero sequence overvoltage element operates when the following conditions are met:



1) zero- sequence voltage is higher than the zero-sequence overvoltage setting value;



2) the circuit breaker is in the aggregate bit;



3) the delay time meets.



Through


the


corresponding


control


word


can


be


set


to


alarm


or


trip,


when


zero


sequence


overvoltage is selected as the alarm device to discriminate self 3U0 zero sequence voltage.



3.5 Low voltage protection



That the system voltage is lower than the tuning voltage determines whether removes the load.



The criterion of low voltage components:



1) three phase-to-phase voltage is lower than the low voltage setting;



2) three- phase current is less than a set value.



3) the circuit breaker in the aggregate bit;



4) the delay time.



3.6 acceleration




the device includes late acceleration by hand and its start conditions are as follows.



1) The time of the circuit breaker is in the OFF position over 30s;



2) the circuit breaker by the sub-gate to closing, accelerated to allow time broadening 3s;



Device independent current accelerating current setting and the corresponding time setting is set.



3.7 Non-electrical protection



The


device


provides


four

the


non-power


protection,


the


by


soft


platen


select


trip


or


alarm. When the the soft platens investment, the non-power movement is in the trip;, non-power


signs only when the soft platen exits.



The device panel lights shows only non-electricity and non-electricity, non-power and non-power


4 of four signal for flexibility. The non electricity significance engineering terminal access. Under


normal circumstances, the default non-power inputs of heavy gas, non- electricity to the input end

3.9 TV break



When operating parameters control word KG1.5 = 0 and selecting star wiring, criterion of bus TV


breaking is as follows:


1) When the phase voltage is less than 8V and some phase (a or c phase) current is greater than


0.04IN ,it is sentenced for three-phase voltage loss;


2) three-phase voltage is greater than 8V, the minimum line voltage is less than 16V;


3)


That


three-phase


voltage


is


greater


than


8V


;the


maximum


line


voltage


and


minimum


line


voltage difference is greater than 16V is sentenced to two-phase or single-phase TV break.


When the operating parameters of the control word KG1.5 = 1


bus PT taking VV wiring and its breaking criterion is as follows:


1) negative sequence voltage is greater than 8V;


2) one phase or two-phase line voltage is less than 70V pressure value;


3)


three-phase


line


voltage


is


less


than


70V

and


a

is


greater


than
