Diaphragm transformer oil conservator

Abstract

The invention discloses a diaphragm type transformer expansion tank. The diaphragm type transformer expansion tank is characterized by comprising an oil storage groove and a diaphragm. An outer edge is arranged on the oil storage groove, a seal ring fastened to the outer edge of the oil storage groove is arranged on the diaphragm by one circle, the inner edge of the seal ring is connected with an annular outer wall which extends downwards along the inner wall of the oil storage groove, and the annular outer wall extends to the groove by 1 / 2-3 / 4 depth of the groove and then folds back upwards. The folding-back section gradually gets close upwards to be closed to form an upwards-heaving flexible membrane cavity, a closed flexible opening is formed in the upper portion of the flexible membrane cavity, a marker post is connected to the upper portion of the flexible membrane cavity, and an upper cover fastened to the seal ring is arranged on the oil storage groove. It can be guaranteed that a transformer always works under stable pressure, seal performance is guaranteed, and maintaining is facilitated.

Description

technical field [0001] The invention relates to a component of an equipment transformer in the electric power industry, in particular to a diaphragm type transformer oil conservator. Background technique [0002] my country has a vast territory and a dense power transmission network. Transformers are needed at the end of the network to convert voltage. Heat is generated during the working process of the transformer. Too high temperature will affect the efficiency of voltage conversion and increase the loss. Therefore, the design of the transformer attaches great importance to the heat dissipation performance. The existing transformers generally use transformer oil to dissipate heat, and transformer oil Only by maintaining stability can the good performance of its heat dissipation function be guaranteed. In order to prevent the transformer oil from contacting with the air to absorb moisture or contact pollutants, and to ensure the purity of the transformer oil, the oil conser...

Heat is generated during the working process of the transformer. Too high temperature will affect the efficiency of voltage conversion and increase the loss. Therefore, the design of the transformer attaches great importance to the heat dissipation performance. The existing transformers generally use transformer oil to dissipate heat, and transformer oil Only by maintaining stability can the good performance of its heat dissipation function be guaranteed. In order to prevent the transformer oil from contacting with the air to absorb moisture or contact pollutants, and to ensure the purity of the transformer oil, the oil conservator often adopts a corrugated oil chamber sealing structure. Although this structure It can avoid the contact between transformer oil and air, but its deformation is small. When it is overcooled or overheated, the transformer oil will generate a certain pressure, and the operation under pressure will affect the life of the seal. Moreover, the oil conservator of this structure is disassembled and maintained. Also troublesome, these still need to be solved by technology
