U-shaped ventilation dustproof photovoltaic box-type transformer substation and using method

Abstract

The invention discloses a U-shaped ventilation dustproof photovoltaic box-type transformer substation and a using method. The transformer substation comprises a box body; a safety door is mounted at the front end of the box body; louvers are formed on the box body at both left and right sides of the safety door; air ducts are formed at the upper ends of the left side and the right side of the boxbody; an exhaust fan is arranged at the upper end inside the photovoltaic box-type transformer substation; each louver comprises aluminium alloy louver blades, a dustproof net, an air inlet frame anda detachable fixed plate; and the aluminium alloy louver blades comprise a plurality of long blades with Z-shaped sections. In the invention, the using method of the transformer substation comprises the steps that: the exhaust fan exhausts hot air in the box body, and cold air enters the box body from the louvers to implement cooling. According to the invention, a problem of temperature rising inside the transformer substation, which is caused by a case that a conventional structure is poor in exhausting performance and the air cannot be circulated, is well solved; the added detachable dustproof net can achieve a dustproof effect and implements easiness for cleaning accumulated dust; and by the louver blades with a specific shape, good ventilating and rain-shielding functions can be achieved.

Description

technical field [0001] The invention relates to a photovoltaic box-type substation and a use method, in particular to a U-shaped ventilation and dust-proof photovoltaic box-type substation and a use method. Background technique [0002] Photovoltaic box-type substation refers to a booster system composed of a combination of low-voltage cabinets, transformer cabinets and booster cabinets in a container. The power supply is provided by solar energy converted into electrical energy by solar cells. With the continuous expansion of the urban area, the electricity load of the urban area increases, and the burden on the substation is also increasing, and the heat dissipation problem of the substation becomes more and more prominent. [0003] At present, most integrated photovoltaic box-type substations use stamping shutters. This outlet structure has many shortcomings. For example, the air outlet of the shutters is small, and the heat cannot be discharged in time, causing the tempe...

AI Technical Summary

Problems solved by technology

[0003] Most of the integrated photovoltaic box-type substations now use stamped louvers. This outlet structure has many shortcomings, such as: the air output of the louvers is small, and the heat cannot be discharged in time, causing the temperature inside the transformer box to rise; the air intake of the louvers is small. , the air inside the substation box cannot fully circulate with the outside world, causing the temperature to rise; without cooling measures, the temperature rise cannot be forced air cooling; the louver holes are not easy to clean after dust is blocked
