Leak detector of capsule for transformer oil conservator

Abstract

The invention relates to a leak detector of a capsule for a transformer oil conservator. The leak detector is mounted inside the capsule for the transformer oil conservator in an overall sealed mode at the lowermost point of the capsule and comprises a liquid collection barrel, a floater and a reed pipe switch, a hollow stand column is mounted inside the liquid collection barrel, the reed pipe switch is fixedly mounted inside a cavity of the hollow stand column, the floater is movably arranged outside the hollow column in a sleeved mode, the floater is provided with a magnet, and a connection terminal of the reed pipe switch is connected with a far-end control center through a circuit board. The leak detector has the functions of alarming capsule fractures, capsule leakage or waterlogging, can monitor a transformer for a long time, can detect potential safety hazard in time, avoid accidental trips of transformer and outages, greatly reduces economic loss, and brings convenience to automatization intelligent control.

Description

technical field [0001] The invention relates to a leakage detection device used in transformers, in particular to a capsule leakage detection instrument for transformer oil conservator. Background technique [0002] Capsules for transformer oil conservator are conventional protection devices commonly used in transformers. Its function is to isolate transformer oil from the air, requiring no oil leakage or water leakage, so as to ensure that the transformer oil is not damp, protect the normal operation of the transformer, and improve Transformer service life. The transformer oil conservator capsules currently used in the market cannot be judged to have ruptured or accumulated water when they rupture and leak or condensation accumulates in the capsule. The tank capsule was removed from the oil conservator to find that the capsule ruptured, leaked or accumulated water. However, at this time, the transformer had unexpectedly tripped and lost power, causing great losses. [000...

AI Technical Summary

Problems solved by technology

The transformer oil conservator capsules currently used in the market cannot be judged to have ruptured or accumulated water when they rupture and leak or condensation accumulates in the capsule. The tank capsule was removed from the oil storage tank to find that the capsule ruptured, leaked or accumulated water, but at this time the transformer tripped unexpectedly and the power was cut off, causing great losses

[0003] With the development of the power transmission and transformation industry, the monitoring of the rupture, leakage or water accumulation of the capsules used in the oil storage tank is an urgent problem to be solved. At present, there are no technical solutions that can solve the above defects.
