A kind of application method of the energy-economic transformer for distribution system, specifically includes the following steps:
Step 1: when transformer is transported to corresponding installation site, staff needs to lift transformer body 1
Upper pedestal 702 on chassis 6 is taken out from lower base 701, so that protective base 8 falls off, protective base 8 is by first
Pedestal 801 and the second pedestal 802 form, and being provided with buffer air bag 804 in the reserved cavity 803 on the first pedestal 801 can
Absorb the vibration being subject to during transformer transporting;
Step 2: the protective base 8 on transformer is removed, and screwed pipe 5 is first inserted into connecting tube 4 by staff,
Further according to the space size of infield, the first arm body 507 of Rocker arm 5 06 is inserted into the groove 503 on brake block 502,
It reuses third arm body 509 and rotates clockwise Rocker arm 5 06 and screwed pipe 5 is rotated into connecting tube 4, adjust protection to reach
The protective range purpose of railing 2;
Step 3: after the protective range for regulating protection railing 2, staff will protect the support column 11 on ceiling 3 to insert
Enter into the connecting sleeve 10 in transformer body 1 and be screwed, support column 11 is fixed i.e. protection ceiling 3 and is fixed
Good, after protection ceiling 3, which is installed to corresponding position by staff;
Step 4: after transformer is installed, user needs to unscrew the limit screw cap 904 on connection bolt 903, makes
Obtaining protective block 901 can rotate, and staff will be after 901 turn away of protective block, the high-voltage line and junction block 9 that will need to access
Protective block 901 is resetted after connecting, then limit screw cap 904 is tightened, the transformer can be begun to use.
The protection railing 2 being arranged first, protection railing 2 are made of vertical bar 201, cross bar 202 and reinforcing bar 203, anti-encirclement
Bar 2 is mounted in connecting tube 4 by screwed pipe 5, and transformer and outside have been separated certain distance by protection railing 2, to manufacture
The space of a safety is gone out, protection railing 2 can will play the role of protection, can effectively reduce transformer and install
After good, passerby accidentally accidentally touching to surprisingly occurring caused by transformer, preferably improve the safety of the transformer, simultaneously
First arm body 507 of Rocker arm 5 06 can be inserted into the groove 503 on brake block 502 by staff, reuse third arm
Body 509 rotates clockwise Rocker arm 5 06 and screwed pipe 5 is rotated into connecting tube 4, to reach the protection for adjusting protection railing 2
Range purpose is mounted in different size of space so that the transformer be allowed to can be convenient, allows the transformer different size of
In space, better protection can be accessed;
Secondly the protection ceiling 3 of setting, protection ceiling 3 are mounted on the connector sleeve in transformer body 1 by support column 11
Pipe 10, protection ceiling 3 can reduce the time that direct sunlight transformer and rainwater directly wash away transformer body 1, slow down change
Components are subjected to transformer parts aging speed caused by washing away in sunshine and rainwater for a long time on depressor, while protecting ceiling
Deflector 301 is provided on 3, the diversion trench 302 on deflector 301 can will protect the rainwater diversion on ceiling 3 to push up to protection
It in rhone 303 in canopy 3, is discharged using drainpipe 304, the length of drainpipe 304 can be high according to the installation of transformer
To be arranged, the lower end of drainpipe 304 can be embedded in flowers and plants degree, be more reasonably utilized rainwater resource, while also subtracting
The situation generation that rainwater washes away transformer leakage caused by transformer and short circuit for a long time is lacked, the transformer is allowed to obtain preferably
Protection;
By the protective base 8 of setting, protective base 8 is made of the first pedestal 801 and the second pedestal 802, in First
Buffer air bag 804 is provided in reserved cavity 803 on body 801 can absorb the vibration being subject to during transformer transporting, from

And it can preferably be protected in various installation sites.
In the use of the present invention, staff needs first by transformer transporting to corresponding installation site, in arriving for transport
Behind corresponding position, staff needs to lift transformer body 1 takes the upper pedestal 702 on chassis 6 from lower base 701
Out, so that protective base 8 falls off, protective base 8 is made of the first pedestal 801 and the second pedestal 802, in the first pedestal
Buffer air bag 804 is provided in reserved cavity 803 on 801 can absorb the vibration being subject to during transformer transporting, thus
The damage that transformer is subjected in transit can be effectively reduced, the transformer is allowed to obtain better protection, by transformation
Protective base 8 on device removes, and screwed pipe 5 is first inserted into connecting tube 4 by staff, big further according to the space of infield
It is small, the first arm body 507 of Rocker arm 5 06 is inserted into the groove 503 on brake block 502, it is clockwise to reuse third arm body 509
Rotation Rocker arm 5 06 is rotated into screwed pipe 5 in connecting tube 4, to reach the protective range purpose for adjusting protection railing 2, prevents
Encirclement bar 2 is made of vertical bar 201, cross bar 202 and reinforcing bar 203, and protection railing 2 is mounted in connecting tube 4 by screwed pipe 5,
Transformer and outside have been separated certain distance by protection railing 2, to be manufactured that the space of a safety, protect 2 energy of railing
It is enough to play the role of protection, transformer can be effectively reduced after installing, and what passerby accidentally accidentally touched arrives transformer
Caused unexpected generation, preferably improves the safety of the transformer, after the protective range for regulating protection railing 2, work
Personnel will be screwed in the connecting sleeve 10 that is inserted into transformer body 1 of support column 11 protected on ceiling 3, support
Column 11 is fixed i.e. protection ceiling 3 and is fixed, and after protection ceiling 3, which is installed to accordingly by staff
Position, after transformer is installed, user need unscrew connection bolt 903 on limit screw cap 904 so that protective block
901 can rotate, and staff will need the high-voltage line accessed to connect with junction block 9 for after 901 turn away of protective block
Protective block 901 is resetted afterwards, then limit screw cap 904 is tightened, the transformer can be begun to use.
