Hello again, Habr! Open a series of articles, photo reports on the construction of our new MTSOD
Module number 3 !

Let's start with a report on the installation of ASU and consumer shields.

Achtung! A lot of crappy photos under the cut!Humbly ask you to forgive me for a certain amount of vertical photos.1. I LIE-3.1. Section number 12. I LIE-3.1. Section number 33. SCHR-1/24. Current progress of constructionI LIE-3.1. Section number 1
In Module 3, this time, we use fully
ABB solutions.
In Module 1 and Module 2, there were billboards filled with
Schneider Electric .

The newly arrived sections of the panel VRU-3.1 for Module №3. ClickableSo far we have acquired one of the two out of the two planned. The main idea of having two ASUs is redundancy and the possibility of different switching in switchboards without interrupting the power supply to consumers.
General view of the section number 1 VRU-3.1, as well as the view without plastrons. ClickableTwo circuit breakers with a nominal value of 400 A - both controlled by ATS. Separately, it should be noted that within the shield itself there is no division of the section into two parts and a sectional switch between them, as it was implemented in the Verkhovna Rada of the first two MCODs.

Electronic trip unit PR223DS ClickableIn addition to traditional protection, trip units measure current. These data, as well as data on the state of the machine, will be transmitted via
Modbus-RTU to the dispatch system.

ATS ATS 022 . I LIE-3.1. ClickableAnd here is ABP3.1. We encounter this hardware for the first time in the data center, in contrast to automata. AVR is pretty smart, plus it measures the voltage and related parameters on the main input buses. Based on whether there is voltage or not, AVR will make a decision about the closing / opening of the automata. The measured data on
Modbus-RTU will also go to the dispatch system.
Automatic Tmax T4N , nominal 250 A. Mounted cables. ClickableThe main purpose of
QF1.1-1.2 automata is to supply power to the main and baypass inputs of UPS-1. The automatic machine
QF1.3 feeds section 3 through the second switch
QS . Automatic
QF1.4 - backup. Normally, the third and fourth automata will be open and locked with padlocks.
HMI 030 panels. I LIE-3.1. ClickableHere everything is clear, man-machine panels for issuing all sorts of statistics.
I LIE-3.1. Section number 3


Some insides section number 3 I LIE-3.1. Plastrons still go, hmm ... ClickableAs you can see from the photos, we have a single section No. 3 with two switchboards
QS OETL 315 from the output of the UPS-1 and from the automatic
switch QF1.3 of section No. 1.
These six circuit breakers
QF3.2-3.7 Tmax T4N with a nominal value of 250 A provide food wp From left to right: the first and the fourth - on ShchR-1 and ShchR-2, the fifth and sixth - on ShchR-3 and ShchR-4, the second and third - reserve.

They are a bit “combed and washed”. ClickableInput power I LIE - 200 kVA. Total 400 kVA per Module №3.

The most important thing in shields. CMS 600 with current transformers. Clickable
Slightly larger. ClickableThese measurement systems came to our liking. Just set up, just organize data retrieval. It is easy and simple to twist a loop of transformers of currents, to specify their spatial distribution on the machine being measured, the order in the loop.
Funny fact: taking into account the future purchase of SchR-3/4, we will have the largest number of CMS 600 current measurement systems in Russia.
And this is also important. B24 counters . The ones who still can not reach us. Photo from ABBMeters will provide us with data on the voltage of the supply bus. These data, as well as data on measured currents from the CMS, will help us calculate the power consumed by the racks. Accordingly, the monitoring of this capacity will allow us to understand whether the client does not exceed the quota allowed for it.
The engine room of Module 3 is designed for the installation of 50 racks.
Estimated power consumption per section - 150 kVA. Accordingly, in total, Module 3 is designed for 300 kVA consumption.

There will be a loading gate with a lift. In the background, posing air conditioning STULZ, SCHR-2 and UPS-1 DELTA. ClickablePS Features of national business ...
- Guys, we paid you for the raised floor tiles and their delivery n-days ago, where are they?
- Oh, and we have already sold them to another client ...
- Guys, according to the documents you delivered the entire profile to us, in fact, we still lack a fifth part, where else is the profile?
- Oh ...
To be continued.
