Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of photovoltaic transformer, in particular, to a conductive protection safety type photovoltaic transformer. BACKGROUND

[0002] The conductive protection safety type photovoltaic transformer is a special transformer used in photovoltaic systems, which is designed to improve safety and reliability. The photovoltaic transformer realizes power transmission through a magnetic coupling device, converts low-voltage direct current at the input end into high-voltage alternating current at the output end, and in this process, the transformer uses the principle of electromagnetic induction to realize the conversion and voltage boosting function by changing the turns ratio of the winding.

[0003] Since the conductive protection safety type photovoltaic transformer is usually installed outdoors and at a high place, it is exposed to the air for a long time, and dust will gradually accumulate on its surface, especially in dry and dusty areas, the speed of dust accumulation may be faster, at this time, the structure of the conductive protection safety type photovoltaic transformer is relatively complex, there are many electrical elements and insulating materials on it, and special care is needed when cleaning to avoid damaging these elements and materials. Generally, the operator stands on a ladder or opens the protective shell outside the transformer at a high place, and then uses a small brush to clean the internal transformer, but since the protective shell is usually made of iron, it will rust after long-term use, and it will be more difficult to open. First, clean the rusty place, then open the door with force. At this time, the operator standing at a high place will be very unstable, and many tools are needed when cleaning, which is not convenient to take in time, and needs to be climbed up and down frequently, affecting the cleaning efficiency.
