Apply for replacement
Dear XXX:
Xx university south campus zi No.2 laboratory building
20 10
year
three
Put into use in the month, at all levels of the school.
With support,
The relocation and construction of our laboratory were successfully completed.
However, due to the differences of different laboratory equipment.
Similarly,
So there are still some problems in some aspects,
Especially parallel computer labs,
For the future
Better study and research,
I hope to get the support of the school ××,
Application for improvement of low-voltage distribution equipment in laboratory
Change.
The reasons for application are as follows:
1.
Parallel computer laboratory
(
C2 16
)
There are parallel computer cabinets
four
Taiwan Province,
Everyone has it.
20
Node service
Equipment, and
five
Microcomputer and air conditioner

Taiwan, stable work rated power can reach.
45,000 watts
, rated current
for
205A
At the same time, the influence of surge current (surge current is stable current) at the start-up moment is considered.
10~20
Times)
, the maximum impact current can be reached.
4000A
, in the case of trying not to boot at the same time, the biggest cabinet.
And pulse current.
1000A
At present, the rated current of laboratory low-voltage distribution equipment is only
100A
far below
The power demand of the laboratory,
Parallel computer terminal room
(
C2 14
)
He micromechanics and weili laboratory
(
C2 10
)
A similar problem is that the rated current is too small.
If the power distribution equipment is not replaced in time,
Even the parallel computer can't work.
Work,
Affect students' study and scientific research,
In addition, the power distribution equipment is burnt out due to overload,
Even happen
It's on fire.

There is no circuit equipment (such as low-voltage lighting box) connected indoors except fluorescent lamps.
, that should be.
No electrical equipment can be used in the office.
Replacement suggestion:
1.
Parallel computer laboratory (
C2 16
)
, parallel computer terminal room (
C2 14
)
, micro-mechanism and micro-mechanism
Force laboratory (
C2 10
) The maximum working current of low-voltage lighting box is
1000~ 1200A

Standard low-voltage lighting box is installed in the room.
I hope and thank the school again for approving our application.
In the future work,
We will continue to work hard,
Constantly innovate and strive to do a better job in the laboratory!
