Auxiliary oil injection device for transformer

Abstract

The invention discloses an auxiliary oil injection device comprises a transformer. The device comprises a transformer body and an auxiliary oil injection device body, an oil injection opening is formed in the top end of the transformer body, the auxiliary oil injection device body comprises a flow distribution box and a control box, the flow distribution box is fixedly installed at the bottom endof the oil injection opening and communicates with the oil injection opening, and a plurality of flow distribution pipes are connected to the bottom of the flow distribution box; the other ends of theflow distribution pipes are arranged downwards and are close to the bottom face of the transformer body, a guide rod is vertically and fixedly installed at the bottom of the flow distribution box, afloating ball type liquid level sensor is installed on the guide rod, a fixing base is fixedly installed on the side, close to the connecting position of the guide rod, of the flow distribution box, and an air pressure sensor is fixedly installed on the fixing base. The auxiliary oil injection device for the transformer is simple and reasonable in structure, novel in design, capable of effectivelysaving oil injection time and improving oil injection efficiency and use safety of the transformer, and is convenient to widely popularize and use.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to an auxiliary oiling device for a transformer. 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 conversion, current conversion, impedance conversion, 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. [0003] However, the existing transformer oil...

Problems solved by technology

[0003] However, the existing transformer oil injection is to directly inject oil into the transformer oil tank through the oil injection hole on the top of the transformer. It is difficult to control the amount of oil injection during oil injection, and the oil with a large flow rate during oil injection is likely to cause damage to the electrical components in the transformer. At the same time, the existing transformer lacks an automatic alarm system for oil volume, which has certain defects
