Description

Dry-type variable air blower and rapid assembly method thereof

Technical Field

The invention relates to the field of dry-type variable fans, in particular to a dry-type variable fan and a quick assembly method thereof.

Background

The dry transformer fan is a dry transformer fan, and refers to a device for cooling a transformer, when a cooling fan is used for the dry transformer, the fan is arranged on two sides of the lower part of a coil of the transformer, and blows cold air into high-voltage and low-voltage cooling air channels of the coil of the transformer directly, so that the heat dissipation effect is obvious, the normal operation of the transformer can be guaranteed, and the service life of the transformer can be prolonged.

The main installation steps of the dry type transformer fan are that firstly, the cooling fan is generally installed beside the lower clamping piece of the dry type transformer, and cold air below and outside is blown into the coil of the dry type transformer, so that the dry type transformer can be fully cooled. During installation, the air outlet of the fan can enter the air duct between the high-voltage coil and the low-voltage coil of the dry-type transformer most smoothly according to the air outlet angle (about 135 degrees from the horizontal included angle) and the air outlet position of the cooling fan, so that the heat dissipation effect is optimal. In order to reduce the vibration of the fan, a rubber block is padded under the bottom foot during installation, and finally, in order to not influence the air output of the cooling fan, a certain distance (generally not less than 10 cm) is kept between an air inlet (which refers to the outer side surface) of the fan and a closed barrier during installation so that air inlet of the fan is smooth, and a ventilation hole is suggested to be formed in a shell near the air inlet of the fan.

The existing dry-type transformer fan is complex in installation steps, more attention is paid to the installation process, if the installation needs to be carried out according to the air outlet angle and the air outlet position of a cooling fan, a certain distance is kept between an air inlet of the dry-type transformer fan and a closed barrier during installation, air inlet of the dry-type transformer fan is smooth, installation personnel need to have quite abundant installation experience, the installation steps need to be strictly installed and preset steps are carried out, once errors occur, the dry-type transformer fan is often required to be completely disassembled for reinstallation, the installation efficiency of the dry-type transformer fan is greatly reduced, and meanwhile the daily maintenance efficiency of the dry-type transformer fan is also severely limited.
