over discharge ,it should separate the battery bank and charger to protect the battery
bank.when power down voltage near to DC23V,it will be into protect battery
modules,all the power function will be invalid at this condition,please switch the power

switch to be off and then on ,the power function will be valid for 1 minus ,after 1
minus ,it will be in protect modules and power switch will be off automatic.
5.7.2 Battery replace
Battery (-) terminal is connected to another battery (+) terminal in serials.battery bank (+/-)
terminals is connected to load (+/-)/charger(+/-) terminal.
6. Movement function
ZW32-RC automatic circuit recloser is used for outlet line of substation or branch point line
to protect line and remove the moment fault and permanent fault as bellowing:
6.1 Protect function of over current

If the line real pass current is over the set over current data ,ZW32-RC will start to remove
the fault current .the active current may set within 20a-1260a,if active current is set in
OFF ,over current protect is not working.also it can be set the delay time of active within
0-60s,if you set the active delay times is 0 which is limited time ,this will make the mistaken
active for moment over current.so it is very necessary to set some delay time.
The annex 1 is data set table
6.2 Quick break function
The quick-break action current and the over-current action current can be set independently, and
the setting range can be changed within the range of 630 ~ 20000A. When setting, it is set to be
faster than the over-current delay time, the delay time can be set from 0 to 10 seconds, and the
number of actions can also be set independently. If the quick-break action current is set to OFF

(closed), the quick-break function will not start, but it will not affect the over-current protection.
action.
See appendix 1 for details：Setting table
6.3 Reclosing function

In order to judge the fault is transient fault or permanence fault,ZW32-RCZW32-RC
Recloser is with recloser function.It will remove the transient fault automatically after one time
power off and reclosing to power on.and if the recloser is matched with sectional load break
switch or sectional circuit recloser to be the automatic feed line ,it need to be setted 3 times
reclosing.The first time is for removing the transient fault ,the second is for disconnect the area
where is with faults ,the third times is for recovery the power on .

By the manual of LCD Display can change the set movement times which can be set as 1 to
3 times.but for the limited of mechanical characteristic ,the second reclosing time and third
reclosing time should be set more than time of saving energy (about 2s to 6s )
I(L) : normal load current t1 : 1st reclosing time

I(PU) : min movement current t2 : 2nd reclosing time
I(F) : fault current t3 :3nd reclosing time
See the annex 1: set data table
6.4 Cold load movement prohibit function
On the power side ,when other line remove the fault and power on again ,the power voltage will
rise higher ,the motor load restarting current will be higher, load momentary current will be 3-4 times
of normal current and the same conditions is existed as in reclosing moment.and after then the
current will be reduce to normal current ,this is called cold load.it will cause mistaken movement of
protect .in order to prevent the mistaken movements of protect ,ZW32-RCZW32-RC Recloser is with
cold load prohibit function.the same for moment current which is 3-4times than normal current .
The moment times is set 1-10times ,if the times is lower than the times of overcurrent
protect ,the cold load prohibit function is off .such as ,if the phase current is 100A ,the movement
times is 4times ,then when the current is below than 100AX4=400a ,The clod load prohibit function
is off .
The schematic diagram as below:

see the data set table 1 in annex 1
6.5 Loss of pressure lockout function
This function can be used when ZW32-RC recloser cooperates with line section load
switch or line section circuit recloser to form feeder automation. This function can also be
allowed or prohibited according to the installation position and line structure of the ZW32-RC
recloser. If you need to set this function, it is best to install the equipment on the load side of the
reverse feed after the tie switch is automatically closed.
It is necessary to set the delay of opening and blocking after experiencing the loss of
voltage. The delay time is usually <0.5s～1s of the automatic closing time of the tie switch.
The operation description is as follows.
Feeder line structure

When a fault occurs between the

substation and the recloser, the
circuit recloser in the substation
will operate
After the recloser starts the

loss-of-voltage lockout function, it
opens and locks to eliminate the
fault area
The tie switch is closed and the

power supply is restored normally
For setting details, please refer to Appendix 1: Setting Table
6.6 load invade movement prohibition function

This function is required for the recloser on the side where there is no fault on the ring network. The
action procedure is as follows:
[ Load current during normal operation ]

[ Overload current during reverse operation ]
At the moment after reclosing relative switch ,the working recloser’s load current will be higher then
normal current to cause overcurrent break.so the normal phase angle current will be set higher than
phase movement current reduce the possible of over load breaking .the normal phase angle is set
as four phase angles with 0.7-0.9.phase angle of the inverse rate (46 ~ 26°).
For setting details, please refer to Appendix 1: Setting Table
6.7 inrush current prohibition protect
it is fixed in recolser without setting
In the event of a power failure, when the backup protection device is switched off and then re-closed,
the inrush current suppression function is automatically activated to prevent malfunction caused by
the transformer excitation surge current.

This function judge the inrush current by compare secondary harmonic wave components
within components of standard wave frequency.

6.8 Single grounding protect phase ( applied for no earthing/resistor earthing /harmonic coil
earthing)
ZW32-RC the recloser adopts the zero-sequence voltage and zero-sequence current
through the high-precision 3-phase voltage sensor and zero-sequence current transformer
installed in the body. Based on the amplitude of the zero sequence voltage V0 and the zero
sequence current I0, the phase angle between the zero sequence current I0 and the zero
sequence voltage V0, the ground fault is comprehensively judged.
ZW32-RCZW32-RC Set the program as following:
■ Allowed/prohibited=set as allowed :allowed protect function of grounding.
■ Tripping=set as allowed :inspection the grounding fault ,and warning of grounding fault but
switch is no tripping (the fault lamp is on )
■ Zero sequence current =set as off :no grounding protect function
■ Zero sequence voltage=set as off :judge the grounding fault only by zero sequence current
(when the location site is near the load terminal ,the load side grounding capacity is more less
than power side grounding capacity)
Grounding fault can be set delay within 1-7200s(2 hours).the standard phase angle and
range is set only after setting the zero sequence voltage and current and when locating site is
in the middle of line , it must be set to judge the load side grounding fault and power side
grounding fault.
The set data is phase

angle of zero sequence
current when the zero sequence voltage phase angle is 0 for different grounding system ,the data

is set as following:
■ The neutral is without grounding /by resistor grounding ,set data is 270° ± 85°.However,
the range can be adjusted according to the operating environment and conditions of the line.
In system of natural is without grounding or resistor grounding .if the load side is with
grounding fault ,the zero current phase angle is located near 270°basing on zero sequence
voltage phase angle.if the power side is with fault ,the zero sequence phase angle is near
90°.so it is easy to judge the direction of grounding fault .so by above description,in system of
no neutral grounding or resistor grounding ,the best phase angle range is 270±85°.of course it
can be adjusted by different line environment and conditions
■ The extinction coils grounding system,data is set as 180° ± 85°

In the extinction coils grounding system ,no matter with in outlet terminal of substation or middle
line or line terminal,when the load side is with grounding fault ,the phase angle is located within ＞
90° ～＜ 180°if over compensate and is located within ＞ 180° ～＜ 270°if no enough
compensate.when power side is with grounding faults the phase angle is with in ＞0°～＜90°.the
best phase angle is within 1800±85°,but you can adjust it by line environment and conditions.
Set data is see annex-1
