How to Design Power Distribution Room for Diesel Generator
by Starlight Generator dieselgeneratortechGenerator power distribution
room is also called the power distribution station. In the Chinese national
standard, the definition of the power distribution station is: "There are
only high-voltage power distribution devices that open and close and distribute
electrical energy, and there is no main transformer on the bus." The
difference between a power distribution station and a substation is that the
power distribution room (distribution station) has no transformer and changes
all transformers. The power distribution room is a key part of the building's
power supply system, and a full-time electrician is assigned to operate on a
24-hour basis. Non-workers are not allowed to enter without the permission of
the manager of the management office or the head of the department. The duty
officer must be certified to work, familiar with the condition of the power
distribution equipment, operating methods and safety precautions.
The duty officer must
pay close attention to the indications of the voltmeter, ammeter, and power
factor meter; the air switch is prohibited from overloading. Always keep the
ground and equipment of the power distribution room dust-free. The switching
operation of the equipment of the power distribution room shall be carried out
separately by the duty officer. The other personnel present shall only be used
for monitoring and shall not intervene; it is strictly forbidden to switch the
two at the same time to avoid mistakes.
Operation Process of
Genset Power Distribution Room
A. High voltage power
distribution room
1. Wear a variety of
insulation equipment (insulated rubber shoes, gloves, helmets, etc.) when
entering a high-voltage power distribution room.
2. Observe the various
instruments and switches in the power distribution room to see if there are any
abnormalities. Wait until the confirmation is correct before operating the
power distribution cabinet. (power transmission and power off)
3. The operation of
power transmission shall be closed from the beginning of the line to the end of
the line, and the closing shall be carried out in strict accordance with the
operating procedures indicated on the power distribution cabinet. If there is
no clear indication on the power distribution cabinet, it shall be in
accordance with the instructions of the professional electric power. Do it one
step at a time. (Use the operating handle to work)
4. Power-off operation
Power-off and power-on are basically the same, in the order of power-on,
reverse power from the outlet, and then step by step to the line-in cabinet.
B. Precautions
1. Every time one step
is completed, the switch should check whether the indicator light on the
electric cabinet is normal. If the indicator light is not bright (not
extinguished) or the color is different from other indicators (dark or
flashing) The current closing, the opening must be re-divided once, and the
gate must be opened in place. Generally, it can be heard from the sound. When
the slamming sound is heard, it indicates that the closing and opening are in
place.
2. It should be noted
that the grounding protection device of the outlet cabinet of the power
distribution cabinet must pay attention to disconnecting the grounding gate
before the power transmission can be turned on. It is also necessary to pay
attention to the power failure. The grounding gate can be closed after opening.
3. It is best to enter the power distribution
room by people familiar with the high and low voltage power distribution room
to avoid an emergency.
4. When the high-voltage
power distribution room is closed, the indicator light of the outlet cabinet is
normal, you can listen to the sound of the transformer. If only the humming
sound is heard, it means that the electricity is normal, and vice versa. Sound,
immediately power off to the transformer room to check, see if the wire is
damaged, there is no debris on it, then cleaned, bandaged, and then re-powered.
5. It is forbidden for
unrelated personnel to enter the power distribution room, no matter whether it
is high pressure or low pressure.
C. Low-voltage power
distribution room. The basic operation is the same as that of the high-voltage
power distribution room. The power is turned on from front to back, and the
power is turned off from the back to the front. Every time you close a gate,
you must see if its corresponding indicator is normal.
D. The environment of
the power distribution room should be kept clean and tidy, keep the ventilation
and dry, especially the temperature of the high-voltage power distribution room
should not exceed 45 degrees, otherwise it will affect the life of the power
distribution room facilities.
E. Inspection and overhaul
Under normal
circumstances, the power distribution room goes in once a month to check
whether the various places can be safely used. The transformers are cleaned
once a year. Wipe the terminals of the transformer and must be powered off and
confirmed that there is no electricity, and the power supply cabinet in the
power distribution room Hang up, "line detection, prohibiting the closing
of power transmission" and other explicit signs. When cleaning the
transformer, use a rag and alcohol to gently clean the dust and so on.
