Description
Technical Field
The utility model belongs to the technical field of photovoltaic power generation, especially, relate to a protector of transformer fuel outlet valve for photovoltaic power generation.
Background
With the rapid development of new energy power generation in the world, photovoltaic power generation has been developed as an essential part of new energy power generation, a transformer of a photovoltaic power station is generally a combined transformer and is installed outdoors, the field environment of the photovoltaic power station is generally harsh environments such as desert, gobi, and the like, the environmental conditions such as temperature, humidity, wind speed and the like are unstable, and the oil drain valve of the transformer is exposed to the outdoor environment for a long time, so that the oil drain valve is damaged by rupture and corrosion due to sand wind, rain, strong temperature reduction and the like.
The transformer oil drain valve is an important component of a transformer, is arranged at the bottom of the transformer, generally comprises a shell, a rotating shaft, a ball valve, a sealing ring, a rubber circle and the like, and is used for discharging oil when the transformer needs to be maintained. In the prior art, a protection device is not additionally arranged, the mode is suitable for the better condition of the power station environment, in most photovoltaic power stations, the operation environment of a transformer is more complex, and the oil drain valve is easy to crack, seep oil, rust and the like; the other kind installs a kind of casing protector additional, and this kind of protector can play certain guard action to the fuel outlet valve, but this kind of scheme arranges the fuel outlet valve in the casing completely, and the staff can not observe the specific situation of fuel outlet valve, and this kind of protector volume is also great, and is comparatively inconvenient in the operation.
Disclosure of Invention
The utility model aims at providing a protector of transformer fuel outlet valve for photovoltaic power generation, solve transformer fuel outlet valve because of receiving the environmental erosion, oil sample sneaks into impurity and makes the sample inefficacy and observe inconvenient scheduling problem when the quality of inspection transformer internal oil.
The purpose of the utility model is realized by the following technical scheme:
the utility model discloses a protector of transformer fuel outlet valve for photovoltaic power generation, its characterized in that includes cylindrical sleeve, sets up the connecting plate of this cylindrical sleeve one end, sets up the lid of the cylindrical sleeve other end sets up on the connecting plate and according to a set of connecting hole of circumference equipartition, set up the lid edge is just connected lid and telescopic a set of bolt, the sleeve through with the screw that the connecting hole is connected with the transformer body.
The cover body is a combination of central toughened glass and edge metal materials.
A gasket is arranged between the sleeve and the cover body.
The length of the sleeve is greater than that of the oil drain valve.
The utility model has the advantages that:
the utility model discloses a protector of transformer fuel outlet valve for photovoltaic power generation, its sleeve opposite side is directly connected with the transformer body, when guaranteeing the connection stability, effectively saves operating space, makes protector more portable; protector is when the protection fuel outlet valve, and the staff can observe under the condition of fuel outlet valve through the glass face of protection device lid at any time to plan to the situation of fuel outlet valve, when the staff takes a sample to oil, can directly go on inside the protector, can guarantee that the oil appearance is not by environmental pollution when taking a sample, when fuel outlet valve damages or rubber circle damages and leads to the oil impregnate, also can follow glass face direct observation.
