Description
Technical field
This application involves gas relay detection technique field, more particularly to a kind of three pipeline gas relay test tables.
Background technology
Gas relay is for a kind of main protective device in oil-immersed transformer.When in oil-immersed transformer
There is turn-to-turn and layer short circuit, iron core failure, inside pipe casing failure, winding inside broken string and insulation degradation in portion and pasta declines
When failure, gas relay can be acted delicately in generation, sent fault alarm in time or cut off event from power grid rapidly
Hinder equipment, so as to reduce the generation of accident, the safe operation to equipment provides a strong guarantee.Gas relay monitor station is to be directed to
Gas relay detection special equipment used in electric system.
Domestic production gas-actuated relay calibration stand is again relatively backward in terms of detection method and accuracy of detection at present, similar
Product mainly uses following methods in terms of flow rate detection:Flow velocity scaling method:This method is to use single-chip microcomputer control technology,
Different bores, different model, the domestic and international gas relay flow velocity scaled data mould of different manufacturers are suitable for by Erecting and improving
The mode of formula.On the basis of flow velocity quantitative measurement is demarcated based on one kind, realize and completed not with the signal piping of same caliber
Same bore, the Buchholz relay school of different model, different manufacturers the heavy gas flow speed value detection of various gas relays both at home and abroad
Test platform.Its method is that a little signal piping is small, small, establishes single benchmark pipeline, when detection and benchmark pipe diameter
Detected value is accurate during consistent gas relay.
Its maximum deficiency be it is following some:Detection and the inconsistent gas relay of non-referenced pipe diameter sectional area
When, the oil stream impact area discreteness that gas relay internal actions element is subject to is larger, at this time by gathering benchmark pipeline stream
Amount flow rate detection value carries out contrast amendment with by the consistent detected value of gas relay bore oil stream sectional area.Such a amendment side
Method is smaller there are error after amendment in gas relay bore and inside consistent into an actor's rendering of an operatic tune physical characteristic structure;As gas after
It is larger there are error after amendment when electric appliance bore and internal an actor's rendering of an operatic tune physical characteristic structure change;Because producing gas both at home and abroad
Relay producer and model are more, cause gas relay internal rows cavity configuration different.At this time, oil stream passes through in gas relay
During portion's an actor's rendering of an operatic tune, caused oil stream property difference is larger.So needed to establish corresponding non-referenced pipe diameter according to These characteristics
The correction factor database of different manufacturers, model, bore in addition, thus cause the method to gas relay detection adaptability compared with
Difference.
