To achieve these goals, the technical scheme of the utility model is following:
A kind of installation component of dry-type transformer cooling blower; Comprise mounting bracket and fixed support; Said mounting bracket and cooling blower Bolt Connection are affixed, and said fixed support and mounting bracket are affixed, and connect transformer body high-low pressure lower clamping piece through spacing jockey.
As the preferred version of the utility model, said mounting bracket is four, is distributed in transformer body high and low pressure side, has first Long Circle hole that installs and fixes six cooling blowers and the circular port that is connected with fixed support on every mounting bracket.
Further, said fixed support is two, have on every fixed support the second Long Circle hole of mounting bracket and be connected with transformer body high-low pressure lower clamping piece greatly enhance circular port.
Further, said spacing jockey is made up of set bolt and the spacing axle sleeve that is sleeved on the set bolt.
Further again, said set bolt is four, and requiring of its length and insulation distance is corresponding.
Further again, said spacing axle sleeve is four, and its internal diameter is than the big 2mm of set bolt.
The utlity model has following advantage according to what such scheme obtained:
(1) matches through mounting bracket and support bracket fastened and should form an organic whole structure with the transformer body after making blower fan install;
(2) fixed structure of double bracket is added the intensity of assembly self, makes the whole erection assembly that enough rigidity will be arranged, and effectively assurance can not produce the increase that causes running noises because of the vibration of blower fan and blower fan erecting device;
(3) through effective cooperation of set bolt and spacing axle sleeve, making has enough safe insulation distances between the live part of blower fan and transformer body coil and lead-in wire;
(4) building block of whole assembly is simple in structure, is convenient to installation and removal, and can satisfy requirement of mass production.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1 and Fig. 2, the installation component of the dry-type transformer cooling blower that the utility model provides mainly comprises mounting bracket 2 and fixed support 3.
Wherein mounting bracket 2 is used for fixing cooling blower 6 is installed, and the mounting bracket 2 that fixed support 3 will be installed with cooling blower 6 through spacing jockey is fixedly attached on the high and low pressure lower clamping piece 11 of transformer body 1 (as shown in Figure 3).
For this reason; Situation to six cooling blowers 6; Referring to Fig. 4 and Fig. 5, mounting bracket 2 is four altogether in the utility model, is distributed in transformer body 1 high-low pressure both sides; The cross section of every mounting bracket is for falling " L " type, the circular port 22 that has the first Long Circle hole 21 that installs and fixes six cooling blowers on it and be used for being connected with fixed support.
For the mounting center that guarantees blower fan overlaps with the three-phase coil center, the position dimension M0 in the first Long Circle hole 21 and hub of a spool are apart from being consistent.
Referring to Fig. 6 and Fig. 7; Fixed support 3 in the utility model is two altogether; The cross section of every fixed support 3 is " L " type, have on it second Long Circle hole 31 of mounting bracket and be connected with transformer body high-low pressure lower clamping piece 11 greatly enhance circular port 32.
