Electrical Apparatus Oil Sampler and Conditioner for Solid State Sensors

摘要

A gas monitoring apparatus and system that provides for reliable and accurate monitoring of gaseous hydrogen and other compounds in dielectric oil. The apparatus provides an environment for and is used in conjunction with metal oxide semiconductor sensors. Thermal conditioning zones for oil provide an environment in which variations in oil temperature and ambient temperature are eliminated to insure that analytical data are not affected by these environmental conditions.

主权项

1. Apparatus for thermally conditioning oil withdrawn from an electrical asset so that the oil may be analyzed, comprising:
a manifold having a chamber; an inlet defining an oil pathway from the electrical asset into the chamber; a gas sensor in the chamber, the gas sensor adapted for direct exposure to oil and for detecting gas in the oil; an outlet defining an oil pathway from the chamber to the electrical asset; a first thermoelectric cooler in communication with the manifold for heating and cooling the manifold; wherein the first thermoelectric cooler is operable to create a substantially isothermal environment for the gas sensor so that gas sensor is operated substantially isothermally.
