Description
Technical Field
The utility model relates to a transformer technical field, concretely relates to dry-type transformer does not have a power failure and changes fan device.
Background
At present, be provided with a plurality of cooling blower among domestic dry-type transformer, generally be 6, cooling blower passes through the bolt and fixes with the dry-type transformer base, and the fan is fixed in dry-type transformer coil bottom completely, and when cooling blower broke down and can not reach the radiating effect, dry-type transformer's coil temperature can continuously rise to threaten dry-type transformer's safe operation, can cause burning out of dry-type transformer when serious.
When a cooling fan fails during operation of the dry type transformer, the failed fan should be replaced immediately, but because the cooling fan is very close to the electrified part of the dry type transformer, the cooling fan can be replaced only when the dry type transformer fails. However, in the actual production, the dry-type transformer cannot be immediately powered off due to the requirement of the production task, so that great contradiction is generated, and the continuity and the stability of the production are severely restricted.
There are two existing solutions: one is that the blower is installed on the transformer outer casing, the lower cover plate of the outer casing cabinet door is made into an integral drawer, the blower is installed in the drawer, when the blower needs to be replaced, the drawer is drawn out for replacement, however, the biggest disadvantage of this method is the noise problem, the noise blower of the dry type transformer accounts for the biggest, mainly caused by the vibration when the blower runs, the blower is installed on the outer casing drawer, because the outer casing thickness is limited, the intensity is poor, the vibration when the blower runs is easy to resonate with the outer casing; the other type is that the fan is arranged on a transformer base trolley, the trolley consists of a longitudinal guide rail and a transverse guide rail, the fan is arranged on the transverse slide rail, when the fan needs to be replaced, the transverse slide rail slides along the longitudinal slide rail to integrally slide out the three fans on the same side of the transformer, and the damaged fan is replaced. The two methods are only suitable for top or side incoming lines of high-voltage and low-voltage cables. At present, the high-voltage cable of the dry-type transformer of the transformer room mostly adopts a bottom incoming line, the high-voltage side cable enters the cabinet and is blocked in front of the middle fan, and the three fans on the high-voltage side cannot be drawn out or slide out simultaneously.
Disclosure of Invention

The front end of the movable bracket 3 is provided with a handle 5.
The damping buffer rail 6 adopts a damping three-section buffer rail.
Each fan 2 is equipped with an air plug 7.
The utility model has the advantages that:
1. the utility model discloses in, 2 bottoms of every fan all are equipped with movable support 3, and adopt damping three section buffering rail between movable support 3 and the fixed bolster 4 for every fan 2 all can realize taking out alone and changing.
2. The utility model discloses in, every fan 2 all is equipped with circular connector 7, and circular connector 7 is used for fan 2 to be connected with the power, and circular connector 7 can be fixed in the section bar of 8 lower part access doors of transformer housing nearby on, during single cooling blower quick assembly disassembly, pulls out its circular connector 7, avoids appearing the electric shock accident.
3. The utility model provides a 3 front ends of movable support are equipped with handle 5, and under the condition that 8 access doors of transformer housing were opened, fan 2 conveniently pulled out and pushed.
To sum up, the utility model discloses can effectively solve among the prior art because of the business turn over line mode messenger fan of transformer high-low pressure side field cable can not realize the difficult problem of wholly taking out.
