A kind of safety switch for wet environment referring to FIG. 1-2, including shell 1 and it is fixedly installed in 1 inner wall of shell
Support platform 2, sealed separation plate 3 is fixedly installed on the top of support platform 2, on shell 1 is divided by sealed separation plate 3
Lower two inner cavities, epicoele are externally connection, and cavity of resorption is seal chamber, protective gas are full of in seal chamber, at the bottom of sealed separation plate 3
End center and the interior bottom center of shell 1 are respectively corresponded equipped with fixed block 4, respectively correspond fixed installation on upper and lower two fixed blocks 4
There are a upper conductive sheet 5 and lower conductive sheet 6, upper conductive sheet 5 and lower conductive sheet 6, which are respectively equipped with conductive lead wire and pass through the inner wall of shell 1, to be connect
To the external terminals 9 being arranged of shell 1, it is hinged in the middle part of the epicoele of shell 1 and positioned at the surface of sealed separation plate 3 and dials
The tip exterior of shell 1 is stretched out on bar 7, the top of driving lever 7, and the bottom end of driving lever 7 is equipped with briquetting 8, and briquetting 8 is bottom great circle head,
When driving lever 7 is allocated to side maximal margin, briquetting 8 leaves the top of sealed separation plate 3, and driving lever 7 is allocated to the maximal margin of the other side
When, the top of the downward sealed separation plate 3 in the bottom end of briquetting 8 may make the upper conductive sheet 5 below sealed separation plate 3 and lower conduction
Piece 6 contacts, and the above-mentioned protective gas by 1 cavity of resorption of briquetting 8, sealed separation plate 3 and shell realizes that the opening and closing of switch controls as a result,
When i.e. briquetting 8 leaves sealed separation plate 3, the protective gas of the lower section of sealed separation plate 3 jacks up sealed separation plate 3 so that on lead
Electric piece 5 and the separation of lower conductive sheet 6, when briquetting 8 pushes sealed separation plate 3, upper conductive sheet 5 and the contact of lower conductive sheet 6.
To so that the current-carrying part of upper conductive sheet 5 and lower conductive sheet 6 is in the confined space below of sealed separation plate 3
It is interior, avoid corrosion of the wet environment to upper conductive sheet 5 and lower conductive sheet 6, meanwhile, contact part because in the confined space, on
Conductive sheet 5 and lower conductive sheet 6 are in closing course, it may occur that discharge and generate electric spark, which will not be to operation
Person brings security threat.On the other hand, the protective gas that seal chamber is filled in shell 1, in 6 institute of upper conductive sheet 5 and lower conductive sheet
Circuit short circuit occurs when, the temperature at upper conductive sheet 5 and lower conductive sheet 6 increases, in protective gas air pressure increase, will
Sealed separation plate 3 jacks up, so that the separation power-off in time of upper conductive sheet 5 and lower conductive sheet 6, further promotes safety in utilization.
Wherein, it is the leakproofness for ensureing sealed separation plate 3 and support platform 2, is fixedly installed at the edge of fixed block 4 close
Bracket 4a is sealed, the edge of fixed block 4 is pressed on the edge of support platform 2 by sealing bracket 4a, and sealed separation plate 3 uses
