This proposal is for
review
and comment only (no ballot at this time).
Please note that
comments
on
apreliminary
review
document
will
not
receive
a
response
from
the
proposal
author through d, the proposal author
will be asked to review the comments and
adjust the proposals and/orsupporting
rationale as the author determines to be
appropriate.
The
preliminary review process is aninformal mechanism
that provides authors with the
opportunity to refine their proposals
before theyadvance to the next stage in UL’s
standards
development process.
In some cases, the author of the
proposals may choose to discontinue them. In this
case,
the authorneed not do anything
after preliminary review has ended. Normally, the
next step in
the
process
is
themore
formal
STP

整提
案和
/
或支持理由。
初步审查过程是一种非正式机制,为作者提供了在
UL
到标准制定过程下一阶段之前完善其
提案的机会。

for later use to supply the utility grid or local
grids. The
energy storagesystem may
utilize one of the following technologies:
a)
ELECTROCHEMICAL
ENERGY
STORAGE
SYSTEM
–
Consists
of
a
secondary
battery,electrochemical capacitor, flow
battery or hybrid battery-capacitor system that
stores
energy andany associated
controls or devices that can provide electric
energy upon demand.
b)
CHEMICAL
ENERGY
STORAGE
SYSTEM
–
Consists
of
hydrogen
supply
equipment
orother fuel supply equipment combined
with a fuel cell power system or generator to
convert
thefuel to electrical energy.
c)
MECHANICAL
ENERGY
STORAGE
SYSTEM
–
Consists
of
a
mechanical
means
to
storeenergy
such
as
through
compressed
air,
pumped
water
or
fly
wheel
technologies
andassociated
controls
and
systems,
which
can
be
used
to
run
an
electric
generator
to
provideelectric energy
upon demand.
d)
THERMAL
ENERGY
STORAGE
SYSTEM
–
Consists
of
an
system
that
uses
heated
fluidssuch
as
air
as
a
means
to
store
energy
along
with
associated
controls
and
systems,
which canbe used to run an electric
generator to provide electrical energy upon
demand.
6.4 ELECTRIC SHOCK HAZARD
–
A potential for exposure
of persons to hazardous voltages
circuitsthrough
direct
contact
from
openings
in
protective
enclosures
and/or
insufficient
insulation betweenhazardous voltage
circuits and accessible parts.
6.5
ENCLOSURE
–
The outer cover
of the Energy Storage System that provides
protection to
itscontents.
6.6 FUEL CELL POWER SYSTEM
–
Equipment that converts
chemical energy in the form of a
fuel
andoxidant into electrical energy with heat and
by-products from the reaction.
6.7
HAZARDOUS VOLTAGE
–
In the United States, voltage exceeding
30 Vrms/42.4 Vac peak or 60 Vdc.
In
Canada, voltage exceeding 30 Vrms/42.4 Vac peak or
42.4 Vdc.
6.8 INSULATION LEVELS
–
The following are levels
of electrical insulation:
a)
BASIC
–
A
single
level
of
insulation
that
provides
protection
against
electric
shock.
Basicinsulation alone may not provide
protection from electric shock in the event of a
failure of
theinsulation.
b)
DOUBLE
INSULATION
–
Insulation
comprising
both
basic
insulation
and
supplementaryinsulation.
c) FUNCTIONAL INSULATION
–
Insulation that is
necessary only for the correct functioning
ofthe equipment. Functional insulation
by definition does not protect against electric
shock. It
may,however, reduce the
likelihood of ignition and fire.
d)
REINFORCED
INSULATION
–
Single
insulation
system
that
provides
a
degree
of
protectionagainst electric shock
equivalent to double insulation under the
conditions specified
in thisstandard.
The term
?
insulation
system
?
?
does not
imply that the insulation has to be in
onehomogeneous
piece.
It
may
comprise
several
layers
that
cannot
be
tested
as
basic
insulationand supplementary insulation.
e)
SUPPLEMENTARY
INSULATION
–
Independent
insulation
applied
in
addition
to
basicinsulation
in
order
to
reduce
the
risk
of
electric
shock
in
the
event
of
a
failure
of
the
basicinsulation.
6.9
RESTRICTED
ACCESS
LOCATION
–
Location
for
energy
storage
system
equipment
where both ofthe
following apply:
a)
Access
can
only
be
gained
by
service
persons
or
by
users
who
have
been
instructed
aboutthe reasons for
the
restrictions
applied to the location
and about any
precautions that
shall betaken; and
b)
Access
is
through
the
use
of
a
tool
or
lock
and
key,
or
other
means
of
security,
and
iscontrolled by the authority
responsible for the location.

shall
be
ventilated
to

concentrations
of

nonhazardous zones of the energy storage system
shall be limited
to 25% LFL undernormal

ventilation relied upon to
maintain

interlocked, so that the system shuts
down upon failure of the

22.2 For battery and
similar systems, openings to prevent hazardous

22.1
包含可向大气排放
氢的易燃流体系统或电池的外壳或区域应通风,
以防止易燃物质的危险浓
度。在正常最大工作条件下,储能系统非危险区域的浓度应限制在
25
%
LFL
。机械通气依赖于将
< br>浓度保持在规定的限度以下,应联锁,以便在通风系统故障时系统关闭。
22.2
对于电池和类似系统,可以使用防止外壳内危险浓度的开口。
应设置通风的外壳中的开口,
以防止因适用的电池技术的电解水电解质导致危险状况的可
燃性气体的积聚,
例如通风或阀门调
