Oil level monitoring device for transformer of 10kV box-type substation

Abstract

The invention relates to the technical field of transformers, and discloses an oil level monitoring device for a transformer of a 10KV box-type substation. The oil level monitoring device comprises anoil tank, wherein two sliding rods are fixedly connected between the inner top wall and the inner bottom wall of the oil tank, a floating block is arranged between the outer surfaces of the two sliding rods in a sleeving mode, and a first triangular plate is fixedly connected to the outer surface of the floating block. According to the oil level monitoring device for the transformer of the 10KV box-type substation, oil in the oil tank is gradually reduced in use, the floating block descends along with the oil liquid level, the floating block drives the first triangular plate to move downwardsuntil to be connected with a second triangular plate, the first triangular plate drives the second triangular plate to move, the second triangular plate drives a third triangular plate to move upwards, the third triangular plate drives the sliding block to move upwards, the sliding block drives a push rod to move upwards, the push rod drives a second idler wheel to move upwards, a knife switch isturned on, a loudspeaker gives out a prompt tone at the moment, and an illuminating lamp is turned on at the same time, so that an acousto-optic reminding effect is achieved, and workers are remindedto add oil in time.

Description

technical field [0001] The invention relates to the technical field of transformers, and specifically relates to a transformer oil level monitoring device for a 10KV box-type substation. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the use, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers , reactors, transformers, etc.).
