Energy-saving environment-friendly dry-type electric transformer

Abstract

The invention provides an energy-saving environment-friendly dry-type electric transformer. The dry-type electric transformer comprises an outer shell, air inlet holes, a frame, a dust filter screen, a drying chamber, a funnel, a left side plate, a first spring, a dust collection box, a second spring and a right side plate. The left end face of the outer shell is provided with the air inlet holes, the framework and the drying chamber are both mounted in the outer shell, and the dust filter screen is mounted in the frame, so that dust filtering and drying of air-cooling air are realized. The funnel is mounted on the lower end face of the outer shell, the upper end of the first spring is fixed to the middle of the lower end face of the left side plate, the upper end of the second spring is mounted in the middle of the lower end face of the right side plate, and the lower end of the second spring is fixed to the right side of the upper end face of the dust collection box, so that centralized dust collection is realized, and air pollution caused by dust flying in air is avoided. Therefore, the energy-saving environment-friendly dry-type electric transformer has advantages of energy saving, environmental friendliness, convenience and quickness in dust cleaning, high stability and high reliability.

Description

technical field [0001] The invention is an energy-saving and environment-friendly dry-type power transformer, which belongs to the field of power equipment. Background technique [0002] Dry-type transformers rely on air convection for cooling and are generally used for local lighting and electronic circuits. Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and other places. Simply put, dry-type transformers refer to transformers whose iron core and windings are not immersed in insulating oil. Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When naturally air-cooled, the transformer can operate continuously for a long time at the rated capacity. When forced air cooling, the output capacity of the transformer can be increased by 50%. It is suitable for intermittent overload operation, or emergency accident overload operation; due to the large increase in load loss a...

Problems solved by technology

[0003] In the prior art, dry-type transformers still have many shortcomings. When using air cooling to dissipate heat, they cannot filter the dust and moisture in the air, causing dust or moisture to enter the dry-type transformer and cause equipment damage. , which greatly shortens the service life of the dry-type transformer, and the air inlet of the existing dry-type transformer is often blocked due to the accumulation of a large amount of dust, resulting in a decline in the heat dissipation effect of the dry-type transformer. Dust cannot be collected centrally, but directly discharged into the air, causing air pollution, so the existing dry-type transformers can no longer meet people's needs, and an energy-saving and environmentally friendly dry-type power transformer is urgently needed to solve the above problems
