00:00:00
hello, dear viewers, today
00:00:03
we will tell you about the old terminal blocks,
00:00:06
what they consist of and how they are assembled,
00:00:10
so the first type is a regular feed-through
00:00:13
terminal consisting of two parts from an
00:00:16
insulator
00:00:17
and from a plate into which it is screwed,
00:00:20
see
00:00:23
the screws here are of a rather original
00:00:25
shape, in principle,
00:00:30
faith under them the power was unpleasant,
00:00:33
they turned out to be such houses,
00:00:35
the only thing was that they placed
00:00:39
washers that limited the ring about
00:00:44
sliding 3 stated
00:00:47
the principles are now used in
00:00:50
various vests pd20 3g 25 there they also
00:00:54
usually put a guyver
00:00:56
1 except for the ra on with you,
00:00:59
I didn’t see it, but the modification of the stained for
00:01:03
cream allows to combine the low-ti
00:01:05
cream electrically with each other it
00:01:11
looks like this, this is how it
00:01:16
is used with them in the kit, there are special
00:01:20
metal contact parts that
00:01:22
have an additional thread in the center
00:01:25
and are used by a jumper that
00:01:30
captures two terminals and the need
00:01:34
to make three or more carrying creams is
00:01:37
installed oak for one
00:01:39
here
00:01:42
now modification number three is a cream
00:01:47
such a cream with disconnectors
00:01:50
swinging like this, this is what it
00:01:53
looks like, the
00:02:00
current transformer is unscrewed here, for example, this is
00:02:02
the load here, and this is where we are
00:02:06
tightened and when checking in the line of protection, you
00:02:10
can twist it, change it, why not
00:02:14
have a groove and this is the herringbone ready-made
00:02:19
enters benz
00:02:22
I will say right away the most convenient design in
00:02:25
principle already
00:02:27
Vadim electricians even very experienced
00:02:30
fell for such a month who this
00:02:34
girl was the amount you are not completely and
00:02:36
more compact
00:02:38
one such things legs are often here there is
00:02:41
also a screw
00:02:45
twisted into the body for installing the bookmark
00:02:48
so current transformers need to be
00:02:51
connected exactly from the side of life
00:02:54
according to our
00:02:56
Delorean
00:02:59
so that they can be bothered with
00:03:01
the need
00:03:03
now,
00:03:06
so to speak,
00:03:08
the need, but usually it doesn’t arise,
00:03:09
usually it arose dismantling the meter,
00:03:12
but as far as I’ve had practice lately,
00:03:20
we always remove the chiki and the disconnected
00:03:23
connection
00:03:25
so that sky and from educational consumption
00:03:28
it can always be organized,
00:03:32
these terminals were installed on such a
00:03:35
quiet configuration of a watering can, which is
00:03:38
still called Zhenya's men because
00:03:42
it is very similar, in such a morning course,
00:03:50
there is an amplifier for this letter, our din-rails
00:03:53
which are
00:03:54
35 millimeters are called but for me,
00:03:57
with nuts, but under the name it is usually not
00:03:59
used, this cream is installed, but in
00:04:02
this way, if you meet 1
00:04:05
time with such terminal blocks, the publishing house will squeeze the cream,
00:04:06
keep in mind that this is done like
00:04:09
this, the pin is squeezed,
00:04:12
we turn it, we release it, it is
00:04:16
fixed with this part, and here you
00:04:18
need a terminal to remove it, you need to
00:04:21
push it towards the wide shelf of the
00:04:24
din rail and just like that, we pull it out in the
00:04:29
same way; the drain cream and
00:04:31
any other
00:04:33
standard spare parts used in
00:04:36
electrical installations are installed; there are usually a
00:04:41
couple of holes at the edges for fastening them;
00:04:44
another thing is a stack like
00:04:49
this, dug it out the task is
00:04:52
to block the cream group so that they are
00:04:55
pressed tightly, in
00:04:56
principle from modern 100 points
00:04:58
used on modern
00:05:00
nicknames its task is no different there are
00:05:03
two installation methods
00:05:05
the most adequate thought there is such a
00:05:08
possibility of growth bring it from the
00:05:12
side by the way the method is also the
00:05:14
only one
00:05:15
possible sometimes bring it from the side
00:05:20
to the desired the place fits tightly and
00:05:23
then tighten the screw,
00:05:25
this bar will press it tightly into place,
00:05:28
there is a second method, the second method doesn’t
00:05:32
always work out, but
00:05:36
it goes like
00:05:37
this, we put it there then we
00:05:40
unfold it, in principle, even if you have
00:05:43
n’t turned it all the way, it will still
00:05:45
hold and tighten it to connect to a
00:05:51
marking system has been developed with this cream, these are the cola heads
00:05:56
that have a tricky shape inside, that
00:06:01
is, on this side they are put on a
00:06:03
wire with a ready-made ring, on this
00:06:05
side this wire, this ring comes out
00:06:08
and when you turn
00:06:09
it is blocked, that is, it did not
00:06:12
fall off,
00:06:14
demonstrating that the ring came out turned around and
00:06:18
everything holds, but it holds, this concept is
00:06:21
relative
00:06:22
3 markers have already flown away today the necessary
00:06:26
necessary things can happen, so he
00:06:29
can easily dream,
00:06:30
but when the ring is connected to the terminal block, he
00:06:34
calmly holds on, doesn’t go anywhere
00:06:37
now the markings of these cream, the abbreviation
00:06:41
Mr. in the center
00:06:42
in diamonds means that cream and issued
00:06:45
according to the standard of the heads of electrical installations, it was
00:06:47
like this when Tess factory letters z and
00:06:51
means a factory of electrical
00:06:53
products, but unfortunately what
00:06:55
the letter r is, I can’t tell you, I don’t know what kind
00:06:58
of factory it was, well, accordingly,
00:07:01
380 volts 20 amperes
00:07:03
are the nominal parameters of the terminals, however, the
00:07:06
current To this day, the Cheboksary
00:07:08
electrical equipment plant
00:07:10
produces terminals to
00:07:12
replace these old ones with new ones,
00:07:15
they are called type-set terminals,
00:07:18
abbreviated z.m. 24 is the series number,
00:07:23
and then there are pass-through measuring and
00:07:26
so on creams that can be installed
00:07:29
absolutely one-on-one instead of those
00:07:33
existing manufactured terminals, we are also intended
00:07:36
for installation on live devices,
00:07:38
but in brief I will say my personal opinion,
00:07:41
these terminals are not of very good quality and
00:07:46
how we would try to put them somewhere,
00:07:50
we really did
00:07:51
n’t like the fact that when we tried to
00:07:54
move away from the ring and make the clamps
00:07:58
just precise
00:07:59
with such a tricky bar like
00:08:03
magnetic starters, they led to the fact
00:08:05
that the wires fall through the cream and the
00:08:07
connection is not very reliable, there is
00:08:11
no confidence the fact that it is
00:08:14
well made, there are also numbered
00:08:18
terminals
00:08:19
on which, for each
00:08:22
cream on each plate, punch a number
00:08:25
in order from 1 to the very end, as it were,
00:08:30
and they were already included in the kit, but what about the
00:08:32
ready-made panels, although in principle all the
00:08:34
cells are already supplied ready-
00:08:37
assembled is impressive, by the way, the installation, please
00:08:40
note that apparently according to the
00:08:43
wire pattern, the wires were folded
00:08:45
very evenly against each other, although the
00:08:48
Cooper insulation has recently been
00:08:51
crumbling, cracking and it’s
00:08:54
time to change it, then a new one, but that will be a
00:08:57
completely different story
00:08:58
until we meet again
