Description

Exhaust device for photovoltaic transformer oil tank Technical Field The utility model belongs to the technical field of photovoltaic transformers, and particularly relates to an exhaust device of a photovoltaic transformer oil tank. Background The photovoltaic power generation system mainly comprises a photovoltaic panel, which is a core part of the photovoltaic power generation system and consists of a plurality of photovoltaic cells, wherein each component has specific functions and works together to convert solar energy into usable electric energy. Photovoltaic cells are typically made of semiconductor materials such as silicon, which are capable of directly converting the energy of sunlight into direct current. Photovoltaic panels can have different efficiencies and power outputs depending on the different needs and state of the art. Inverter because the power generated by the photovoltaic panel is direct current and the power used by most households and grids is alternating current, the inverter is required to convert the direct current into alternating current. The inverter may also provide system monitoring functions and protect the system from electrical faults. And a transformer for distributing and managing the power from the inverter to ensure safe power supply to the respective loads. It may contain circuit breakers, fuses and other protection devices to protect the system from electrical faults. The gas relay is also called as gas relay, which is a protecting element of transformer by using hot oil flow and hot air flow generated when the transformer fails to work, and is installed on the pipeline between the oil conservator and oil tank of transformer. At present, the existing automatic exhaust device of the transformer with the bulletin number of CN214956328U and the transformer comprise a gas relay, an exhaust pipe connected to the gas relay, and a manual exhaust valve and an automatic exhaust valve which are arranged on the exhaust pipe, wherein the gas relay is arranged on a pipeline between a conservator of the transformer and an oil tank of the transformer. The manual exhaust valve is located at the top of the gas relay, the exhaust pipe and the automatic exhaust valve connecting section are arranged in the vertical direction, and the automatic exhaust valve is located at the top of the exhaust pipe. The automatic exhaust valve is reasonable and compact in structure and convenient to use, the gas outlet of the manual exhaust valve is connected with the gas outlet pipe by opening the manual exhaust valve of the gas relay, and the automatic exhaust valve is arranged on the gas outlet pipe, so that when gas is generated in the transformer, the gas can be exhausted through the automatic exhaust valve, the safe operation of the transformer is ensured, manual exhaust operation is not required, and the personal safety of transformer substation staff is ensured. However, there is a problem in that the exhaust pipe is often required to be manually opened, which is troublesome. The electronic exhaust valve is complex in structure, difficult to maintain and high in cost. Disclosure of utility model The scheme provides a photovoltaic transformer oil tank exhaust device for solve the problem that the valve structure of current blast pipe is complicated, difficult maintenance.
