Dry-type transformer blade-free cooling fan device and application method thereof

Abstract

The invention relates to a dry-type transformer blade-free cooling fan device and an application method thereof. The dry-type transformer blade-free cooling fan device comprises a dry-type transformer, a blade-free cooling fan, an insulated infrared temperature measurement sensor and a control module. The blade-free cooling fan is arranged near to the dry-type transformer, faces a winding of the dry-type transformer directly and is used for blowing air to cool the winding of the dry-type transformer. A temperature measurement probe of the insulated infrared temperature measurement sensor is arranged near to the winding of the dry-type transformer, faces the center of the winding of the dry-type transformer and is used for measuring the temperature of the winding of the dry-type transformer in a non-contact mode. The blade-free cooling fan is connected to the control model through a control cable. The insulated infrared temperature measurement sensor is connected to the control module through an infrared optical fiber sensing data line. The dry-type transformer blade-free cooling fan device and the application method thereof have the advantages that forced air-blowing cooling for the dry-type transformer is controlled automatically by the infrared non-contact temperature measurement, sensing and control technology, so that operational copper and iron losses of the dry-type transformer are reduced effectively, and overload and short-circuit resistance capacities of the device are improved effectively.

Description

technical field [0001] The invention relates to the field of dry-type transformer cooling fans, in particular to a dry-type transformer bladeless cooling fan device and a use method. Background technique [0002] During the operation of the dry-type transformer, due to the electromagnetic effect, its winding will generate a lot of heat, which needs to be cooled by the air flowing around it, otherwise it will cause a vicious accident of burning the dry-type transformer. Nowadays, the cooling methods of traditional dry-type transformers are divided into natural air cooling and forced air cooling. Natural air cooling has low cooling efficiency. To cool the windings of dry-type transformers, the traditional dry-type transformer cooling fan has many disadvantages: the exposed high-speed rotating blades are unsafe, high energy consumption, short service life, loud noise, easy to accumulate oil and dust, and difficult to maintain and clean, etc. Moreover, the traditional dry-type ...
