The invention provides a gas relay. The gas relay comprises a position sensor and a relay body, wherein a transparent window is arranged on the side edge of the relay body, and a floater capable of floating up and down along the liquid level is arranged in the relay body; the position sensor is arranged outside the transparent window and used for emitting detection light to the inner side of the transparent window; and when it is detected that the light is shielded, the position sensor generates an alarm signal. According to the gas relay provided by an embodiment of the invention, the alarm signal can be generated in advance before the floater reaches a trigger position, so a worker can find a fault or an abnormity in advance and can carry out treatment such as maintenance in advance, and the problems of oil injection, explosion and the like of equipment such as a transformer due to serious faults are effectively avoided, and the personal safety of the worker can be effectively ensured ...

The invention discloses a device and method for increasing the oil temperature of a transformer and application, and relates to the technical field of transformers. The device comprises a first transformer, a second transformer, a heat exchanger, a first pump, a second pump and a controller, and the first transformer is connected and communicated with a first heat exchange pipeline of the heat exchanger through the first pump to form a first circulating oil way; the second transformer is connected and communicated with a second heat exchange pipeline of the heat exchanger through a second pump to form a second circulation oil way. The controller is used for starting the first pump and the second pump and enabling the first circulation oil way and the second circulation oil way to conduct heat exchange. The method comprises the steps that the controller learns that the oil temperature of the first transformer is low, the first pump and the second pump are started, and heat exchange is conducted ...

The invention discloses a device and method for reducing the oil temperature of a transformer and application, and relates to the technical field of transformer cooling. The device comprises a first transformer, a second transformer, a mixer, a first pump and a controller, the first transformer is connected and communicated with the mixer through the first pump to form a first circulating oil way, and the second transformer is connected and communicated with the mixer through the first pump to form a second circulating oil way. The controller is used for starting the first pump and mixing oil of the first circulating oil way and oil of the second circulating oil way, and the controller is electrically connected with the first pump; the method comprises the steps that when the controller knows that the oil temperature of any transformer exceeds the upper limit temperature, the first pump is started, oil of the first circulating oil way and oil of the second circulating oil way are mixed, ...
