Device for detecting winding humidified insulation of synchronous phase modifier

Abstract

The invention discloses a device for detecting winding humidified insulation of a synchronous phase modifier. The device comprises a plurality of humidity sensors, a current amplifier and a display, wherein the plurality of humidity sensors are arranged at winding insulation portions of the synchronous phase modifier respectively, and are used for detecting whether the winding insulation of the synchronous phase modifier is humidified; the current amplifier is connected with the plurality of humidity sensors, and is used for amplifying current signals; and the display is connected with the current amplifier, and is used for displaying the amplified current signals. When the winding insulation of the synchronous phase modifier is humidified, the current is displayed on the display, the winding humidified insulation condition can be detected without disassembling the synchronous phase modifier, the convenience of detection is improved, the humidified condition of the winding insulation is determined according to the waveform of the current, and the problem of immeasurable economic loss caused by machine halt, furnace shutdown or even host damage after the winding insulation is humidified when a large-scale motor adopts an internal water cooling system is solved.

Description

technical field [0001] The invention relates to the technical field of detection of dampness of motor insulation, in particular to a device for detecting dampness of winding insulation of a synchronous condenser. Background technique [0002] With the large-scale promotion and application of UHV DC transmission projects and the rapid development of new energy grid-connected, the use of new large-capacity condensers to provide dynamic reactive power support for the grid and improve the safe and stable operation of the grid has become more and more popular in the domestic and foreign power transmission industry. attention. [0003] In the prior art, many large motors adopt water internal cooling system, and the winding insulation of water internal cooling generator is an important part of the generator stator. Its tightness and integrity are the key to ensure the long-term normal operation of the generator, and its maintenance is very important . But now the problem of damp ...
