Silicone deliquescence self-judging device in main transformer respirator

Abstract

The invention relates to a silicone deliquescence self-judging device in a main transformer respirator. The device comprises an isolation disc, a lifting transmission component, a hydraulic expansionsealing component, a multi-phase power switching device, a deliquescent particle self-judging transport device, a self-determining measuring rod component and anti-blocking struts. A bottom of the isolation disc is fixedly connected to a plurality of the anti-blocking struts in a circumferential direction, the hydraulic expansion sealing component comprises an annular oil cylinder set on a side ofthe isolation disc and an annular rubber pad which is fixedly connected to a side of the isolating disc and is used for sealing the annular oil cylinder, the annular oil cylinder is communicatively provided with a plurality of centrally symmetric hydraulic cylinders in circumferential distribution close to an inner wall of a center end of the isolating disc, the hydraulic cylinders are provided with annular transmission cavities close to the center end of the isolating disc, a first adjusting screw is rotatingly connected between the annular transmission cavities and the hydraulic cylinders,and one end of the first adjusting screw extends into the hydraulic cylinders and is threadingly connected to a piston which is slidingly connected to the first adjusting screw.

Description

technical field [0001] The invention relates to the technical field of substation protection, in particular to a self-judgment device for silica gel deliquescence in a respirator of a main transformer. Background technique [0002] With the development of society and the advancement of technology, electric energy has become one of the most important energy sources at present. In the process of electric energy transmission, in order to be able to transmit electric energy to the designated power consumption place with long-distance and low loss, it is necessary to use a transformer at the starting point. The voltage will be raised, and at the end of use, the voltage needs to be reduced to a low voltage suitable for use. [0003] The basic structure of a transformer consists of a body, an oil tank, a cooling device, a protection device, an outlet device and transformer oil. The body includes iron core, winding, insulation, lead wire and tap changer; the fuel tank includes the ...

Problems solved by technology

[0013] From the function and installation characteristics of the respirator, it can be found that the deliquescence self-judgment of the adsorbent silica gel inside the existing respirator has problems, which will cause the oil to be in contact with the air, and the oil will be damp and oxidized. Air bubbles enter the transformer, drying the air and failing to filter, thus making it impossible to keep the insulating oil in the transformer oil tank clean

The total amount of silica gel is two-thirds of the glass cover when it is added, and its original color is blue. When deliquescence occurs during work, it changes color from the bottom to the top. However, the deliquescence intelligence of silica gel inside the existing respirator can be viewed directly It can only be learned by means of manual operation that the replacement of the adsorbent is delayed due to the slow delay of manual operation, resulting in damage to the transformer, and may even cause a greater accident. judging device
