Description
Technical field
The present invention relates to high voltage distribution installation technical field, be specifically related to a kind of pneumatic mechanism for circuit breaker leak hunting method.
Background technology
Along with the growth of pneumatic mechanism for circuit breaker service life, there is gas leakage phenomenon in increasing pneumatic mechanism,
Have a strong impact on pneumatic mechanism normally to work.So the leak detection work of mechanism must be quick, accurately.The leak detection of pneumatic mechanism at present has
Two kinds, one is visual examination method, i.e. experiences concrete air leak position by means such as seeing, listen, touch, and another is soap bubble
Method, i.e. smears soap bubble at the position that may leak gas, by abnormal soap bubble, finds the position of gas leakage.But both approaches
All there is drawback, particularly the first is more difficult to find out air leak position, because pneumatic mechanism air leakage is typically small, passes through
The difficulty of reflection directly perceived is the biggest.Although second method also can find out small gas leakage, but has multiple position can not smear soap
Bubble, because mechanism has many places to be depressed area, so can not hunt leak these positions, secondly, the high pressure on primary cut-out is empty
The pipe joint of gas system is typically all copper or ferrous material product, in order to judge leak source, needs to smear at all pipe joints
Suds, if process the most thorough to the suds smeared afterwards, it will produces rusty stain at pipe joint, causes the most air tight
Joint leak gas owing to getting rusty.Further, since limited some position by equipment design size cannot be applied to soap at all
Water, leaves dead angle for equipment leak detection, affects the unitary analysis to equipment operation condition and the formulation of Corresponding Countermeasures, this leak detection
Method is all not reaching to expected effect during repeatedly leak detection.

Body, charging connector and air gauge, described device body is processed by a monoblock stainless steel material, and described device body is provided with
Three holes connected, these three holes are respectively used to install charging connector, air gauge and pneumatic element to be detected.This utility model
Can be used for detecting multiple pneumatic element leakage situation, efficiently solve pneumatic unit on equipment and use multiple pneumatic elements, and
Cannot determine which occurs the problem leaked, thus shorten the equipment fault diagnosis time, improve production efficiency.This leak detection
Device needs to take pneumatic mechanism apart and just can hunt leak, and is easily found leakage point.
The disclosure of the invention of Application No. 201210259571.8 gas leak detection method of primary cut-out SF6, belongs to
In electric power system detection field, when the present invention solves conventional leak test plant leak detection, the mistake brought due to insensitive, inaccuracy
Judge, delay fault time, it is impossible to the problem ensureing the stable operation of electric power system.The inventive method comprises the following steps: step
Rapid one, uniformly brush with speckling with the hairbrush of the suds cabin sealing surface along primary cut-out SF6；Step 2, bubble is occurring
Leakage point marking pen is marked；Step 3, with live pull in by the sealing surface of leakage point position described in step 2
Nut fastens；Repeated execution of steps one to step 3, until when uniformly brushing with the hairbrush speckling with suds, height breaks
Till road device SF6 does not has bubble to produce.This invention is detected by suds, uses limitation bigger.
