Description

TECHNICAL FIELD

[0001] The present application relates to the field of dry-type transformers, in particular to a dry-type transformer based on photovoltaic power generation with explosion-proof and noise reduction functions. BACKGROUND

[0002] A dry-type transformer is a coil insulated from each other and sleeved on a common core column. When a high-voltage coil is supplied with a power frequency three-phase rated voltage, an alternating magnetic field is generated in the core by the current in the coil. According to the law of electromagnetic induction, an alternating potential of the same frequency is induced in the high and low voltage coils. The low voltage coil has a potential and can supply power to the load. It is mainly used in power systems, industrial production, commercial and civil fields, etc.

[0003] With the development of the photovoltaic industry, dry-type transformers have gradually been introduced into the field of photovoltaic power generation. However, the operation of the dry-type transformer requires a higher environment, and it needs to be used indoors, and a case is usually needed on the outside, resulting in high application cost. Moreover, the existing dry-type transformer does not have excellent explosion-proof and noise reduction properties, resulting in high noise during operation and the risk of explosion.

[0004] The dry-type transformer disclosed in the publication No. CN116978662A includes a transformer body, a frame, and a shielding mechanism. The frame has an installation cavity inside, and the transformer body is arranged in the installation cavity. The frame has openings on both sides along the first direction, which are in communication with the installation cavity. The shielding mechanism includes a winding assembly and two screen nets. The two screen nets are arranged at the two openings, respectively. The screen net is provided with air holes for air to enter and exit the installation cavity. The frame also includes a top plate. The winding assembly includes a winding roller, which is rotatably arranged on the outside of the top plate. One end of each of the two screen nets is connected to the winding roller to wind the screen net. The winding roller simultaneously winds or unwinds the two screen nets, so that the two screen nets selectively cover the openings. At the same time, the screen net can use the air holes to allow air to enter and exit the installation cavity, thereby protecting the transformer body without affecting the heat dissipation capacity of the transformer body.

[0005] The above technical solution can protect the dry-type transformer from dust and does not affect the heat dissipation effect. However, it still has a high use cost and cannot effectively prevent explosion and reduce noise. Therefore, a dry-type transformer based on photovoltaic power generation with explosion-proof and noise reduction functions is proposed. SUMMARY
