Abstract

The invention discloses an oil immersion device of a transformer, through which the oil level does not fluctuate in the process of performing oil immersion on the transformer. The oil immersion device for the transformer comprises an oil groove and a bracket of the oil groove and also comprises a programmable logic controller (PLC) control system, wherein the middle part of the bracket sinks downwards, a secondary groove is arranged in the oil groove and is positioned below the bracket; a driving device for driving the secondary groove to move up and down is arranged outside the oil groove; and the driving device is electrically connected with the PLC system. The oil immersion device has the advantages that the oil level is flat and does not fluctuate by using the secondary groove, so that the oil immersed height is consistent when the transformer is immersed in oil, and the subsequent soldering tin accuracy can be guaranteed.

Description

technical field

[0001] The invention relates to an oil immersion device for a transformer. Background technique

[0002] Such as figure 1 As shown, the traditional transformer impregnated insulating oil device includes a vacuum cylinder 9 and an oil cylinder 8 arranged below it. The oil cylinder 8 and the vacuum cylinder 9 are connected by a pipe 10 , and a valve 12 is provided on the pipe 10 . A support 2 for placing a transformer 11 is arranged inside the vacuum cylinder 9 . Its working principle is: the oil cylinder 8 storing insulating oil and the vacuum cylinder 9 are separated. When in use, the vacuum cylinder 9 is pumped into a negative pressure vacuum by an air compressor, and the insulating oil is drawn from the lower oil cylinder 8 by pressure. Pumped into the vacuum cylinder 9 storing the transformer 11 through a pipe 10, controlled by the opening size of a valve 12, the liquid level of the oil is visually measured with human eyes, and the valve 12 is closed aft...

Embodiment Construction

[0013] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] Such as figure 2 , image 3 As shown, the oil immersion device of the transformer according to the present invention includes an oil tank 1, a support 2 and a PLC control system 3 fixed in the oil tank 1 with a downwardly recessed middle part, and a recessed part is set in the middle part of the support 2 for shelving the transformer 11. The edge is higher than where the transformer 11 is located, and the upper edge of the sub-slot 4 will not touch the support 2 when it rises, so that the transformer 11 can be located in the sub-slot 4 and contact the insulating oil. Because the PLC control system 3 has no requirements on the position, it can be set at any position that can be placed. Described oil groove 1 is provided with sub-groove 4, and sub-groove 4 is positioned at the below of support 2, and the outer side of oil groove 1 is p...
