Description

Outdoor safety detection monitoring device for transformer substation

Technical Field

The invention relates to the technical field of transformer substations, in particular to an outdoor safety detection monitoring device for a transformer substation.

Background

Transformer substation, place of changing voltage. In order to transmit the electric energy generated by the power plant to a remote place, the voltage must be increased to become high voltage, and then the voltage is decreased as required near the user, and the voltage increasing and decreasing work is completed by a transformer substation. The main equipment of the transformer substation is a transformer, and the larger the capacity of the transformer is, the larger the corresponding loss and heat productivity is, the more difficult the heat dissipation is. And therefore more aggressive cooling measures are required. In the prior art, the cooling modes of the transformer include an oil-immersed self-cooling type and an oil-immersed air-cooling type.

The oil immersed self-cooled transformer has no special cooling equipment. The heat generated by the iron core and the winding is transferred to the oil tank wall or the radiating fins by the convection action of the oil, and then is radiated to the outside by the radiation action of the radiating fins fixed on the oil tank wall or the outer wall and the natural convection action of the surrounding cooling air. However, when the natural wind speed is low and the heat of the transformer is high, the heat may not be dissipated in time, so that the temperature of the transformer is too high.

The oil immersed air-cooled transformer is characterized by that one or several fans are mounted beside every radiating fin of oil tank of transformer, and the natural convection action is changed into forced convection action so as to raise the radiating capacity of radiating fin. To improve the operating efficiency, the fan may be stopped and the transformer may be operated in a self-cooling manner when the load is small. The fan can be automatically put into operation when the load exceeds a certain specified value, for example 70% of the rated load. However, because the size of the fan is limited, the distribution of the heat dissipation fins of the oil-immersed air-cooled transformer is concentrated, and because of the shielding effect of the fan, the self-cooling heat dissipation efficiency is low, the fan needs to be operated frequently, and the energy consumption is increased.

Therefore, it is necessary to provide an outdoor security detection monitoring device for a substation to solve the problems in the background art.
