Heat-dissipating dry-type transformer and online early warning system thereof

Abstract

The invention discloses a heat-dissipating dry-type transformer and an online early warning system thereof. The heat-dissipating dry-type transformer includes a bottom plate, wherein two support basesare symmetrically disposed on the top of the bottom plate; the tops of the two support bases are fixedly connected through a box body; a positive and negative motor is fixedly connected with a midpoint on the top of the box body; and a positive and negative rotating shaft is fixedly connected to the output shaft of the positive and negative motor. The heat-dissipating dry-type transformer, through the cooperation of the positive and negative motor, the positive and negative rotating shaft, cooling blades, a rolling bearing, a threaded rod, a first bevel gear, a second bevel gear, a threaded sleeve, a heat dissipation port, a rotating shaft, a fixed rod, an impact hammer, a rope, and a vent, has a good heat dissipation effect, can intermittently clean the dust on a dust net, avoids the situation that the heat generated by the dry-type transformer body inside the box body cannot be dissipated because of a large amount of dust accumulated on the dust net, improves heat dissipation efficiency, and prolongs the service life of the dry-type transformer body.

Description

technical field [0001] The invention relates to the technical field of dry-type transformers, in particular to a heat-dissipating dry-type transformer and an online early warning system thereof. Background technique [0002] Dry-type transformer refers to the transformer whose iron core and winding are not immersed in insulating oil. Dry-type transformer is widely used in local lighting, high-rise buildings, airports, wharf CNC machinery and equipment, etc. The cooling method of dry-type transformer is divided into natural air cooling And forced air cooling, when natural air cooling, the transformer can run continuously at the rated capacity for a long time, when forced air cooling, the output capacity of the transformer can be increased by 50%, suitable for intermittent overload operation, or emergency overload operation; due to overload When the load loss and impedance voltage increase greatly, it is in a non-economic operation state, so it should not be operated continuou...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a heat-dissipating dry-type transformer and its online early warning system, which has the advantage of good heat dissipation effect and solves the problem of unsatisfactory heat dissipation of common dry-type transformers; the early warning system analyzes the gas composition in the transformer Concentration to judge the heating status of the equipment in the cabinet, and effectively monitor the equipment operation status of the transformer
