Vehicle-mounted transformer oil conservator

Abstract

The invention provides a vehicle-mounted transformer oil conservator. The switch oil conservator is independently arranged on the end face of one side outside the main oil conservator, materials needed by the switch oil conservator can be saved, it is guaranteed that the internal structure of the main oil conservator is regular, and capsule sealing is facilitated. In order to facilitate an operator to maintain the oil conservator, a main oil conservator breathing channel, a vacuumizing channel and a switch cabinet breathing channel of a switch oil conservator are conducted and connected together through a pressure balance valve, and the three channels extend to the lower portion of an oil tank along the outer side of a transformer body. Respirators and valve structures at the tail ends of the channels are ensured to be located at the height positions close to maintenance personnel, and vacuumizing oil injection of the transformer, overall sealing test of the transformer and follow-up maintenance operation are more convenient. Therefore, the vehicle-mounted transformer oil conservator and the switch oil conservator can be separately and independently designed, operation of maintenance personnel is facilitated, the occupied volume of the oil conservators can be reduced, and the transformer is integrated to meet the vehicle-mounted installation space requirement.

Description

technical field [0001] The present application relates to the technical field of power transformers, in particular to a vehicle-mounted transformer oil conservator. Background technique [0002] In order to improve the mechanical strength of the oil conservator, facilitate the blanking of the plates and simplify the welding process, the cross-section of the traditional oil conservator is generally designed to be circular, and the overall shape of the oil conservator is barrel-shaped. However, the installation space of the cylindrical oil conservator will be relatively high, and the vehicle-mounted transformer cannot directly adopt the existing cylindrical oil conservator structure due to the outer limit size requirements. [0003] Other existing oil conservator can also be designed as a rectangular structure in cross-section. At this time, in order to match the shape of the main main oil conservator, it is generally necessary to set the switch oil conservator as a square str...

AI Technical Summary

Problems solved by technology

The shape of the oil conservator with a square structure is not beautiful, the material is more, the length is longer, and it takes up a lot of space on the tank cover, and it needs to occupy the upper space of the top cover of the on-load switch above the transformer.

Such a structure of the oil conservator is not conducive to the inspection and maintenance of the on-load switch on the top of the transformer

[0004] In addition, the existing oil conservator still has messy and unsightly arrangement of pipelines, the length of the main air pipe connected to the transformer box cover is long, the space for the box cover is difficult to arrange, and maintenance operations such as vacuuming and oil filling of the oil conservator are inconvenient, etc. question
