Description
Technical field
The utility model relates to electric power system high-potting utensil, particularly a kind of micro-water test splice of SF6 air insulating device securing means that micro-water test instrument joint is connected fast with the micro-water test splice of SF6 air insulating device.
Background technique
We know, < < power transmission and transformation equipment state overhauling testing regulations > > will look for novelty and put into operation, after tonifying Qi and every 4 to the 5 years all air chambers of reply SF6 air insulating device carry out micro-water test.The current micro-water test splice of SF6 air insulating device is divided into silk mouthful design and flange mouth designs two kinds, wherein, silk mouthful test splice can be connected by silk mouthful easily with microwater device joint, its deficiency is gas leakage, become flat, and flange mouth test splice is while carrying out the test of micro-water, for overcoming gas pressure in equipment, tester needs very large pressing force fixing test instrument joint, conventional method is that two people coordinate, wherein people's both hands will compress micro-water testing instrument joint, another people is fixed with bolt, for avoiding bolt degree of tightness to differ, damage equipment thimble, in fastening process, needing circulates successively tightens each bolt, this just causes the test head of flange mouth design to connect consuming time long.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of easy to operate, use the micro-water test splice of SF6 air insulating device securing means safe, air tight, quick connection.
The utility model can reach by following measure:
The micro-water test splice of a kind of SF6 air insulating device securing means, it is characterized in that being provided with the cylinder shell of placing micro-water test splice, the panel of housing front end is provided with circular air chamber attachment hole, shell body wall after panel is provided with and is connected the draw-in groove that boss matches with air chamber, in housing, be provided with cushion block, housing upper end is provided with and the nut that advances screw mandrel to match, and propelling screw mandrel and nut match to merge and stretch in housing, advance screw mandrel outer end to be provided with rotatable handle.
Housing described in the utility model underpart is provided with two draw-in grooves, and two draw-in grooves are symmetrical set, so that it is connected reliably with air chamber.
Cushion block described in the utility model is provided with anti-rotation screw, and housing is provided with the locating slot matching with anti-rotation screw, and locating slot is the straight line shape with housing shaft line parallel.
When the utility model is used, first by housing lower end, the boss that is connected on draw-in groove and tested air chamber survey mouth matches, make the air chamber attachment hole of housing lower end just to air chamber, detect mouth, again micro-water test splice is placed in the housing under cushion block, by rotatable handle, make to advance screw mandrel to move down, advance screw mandrel promotion cushion block pressing micro-water test splice to move down and press off air-chamber valve and carry out air chamber pressure detection, because cushion block is provided with anti-rotation screw, guarantee that test splice does not rotate displacement in connection procedure, the manual propeller of leading screw replaces the artificial process that compresses test splice, and the two is connected closely to make the micro-water test splice of microwater device joint and SF6 air insulating device with anti-rotation cushion block cooperation, stressed even, have and be easy to carry, easy to operate, use safety, working efficiency is high, testing precision advantages of higher, alleviated greatly operator's labor intensity.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in the figure, the micro-water test splice of a kind of SF6 air insulating device securing means, be provided with the cylinder shell 1 of placing micro-water test splice, the panel 2 of housing 1 front end is provided with circular air chamber attachment hole, shell body wall after panel 2 is provided with and is connected the draw-in groove 3 that boss matches with air chamber, in housing 1, be provided with cushion block 4, housing 1 upper end is provided with and the nut 6 that advances screw mandrel 5 to match, propelling screw mandrel 5 matches to merge with nut 6 and stretches in housing 1, advance screw mandrel 5 outer ends to be provided with rotatable handle 7, described housing 1 underpart is provided with two draw-in grooves, two draw-in grooves are symmetrical set, so that it is connected with air chamber reliably, in addition, cushion block 4 described in the utility model is provided with anti-rotation screw 8, housing 1 is provided with the locating slot 9 matching with anti-rotation screw 8, locating slot 9 is the straight line shape with housing shaft line parallel, when the utility model is used, first by housing lower end, the boss that is connected on draw-in groove and tested air chamber survey mouth matches, make the air chamber attachment hole of housing lower end just to air chamber, detect mouth, again micro-water test splice is placed in the housing under cushion block, by rotatable handle, make to advance screw mandrel to move down, advance screw mandrel promotion cushion block pressing micro-water test splice to move down and press off air-chamber valve and carry out air chamber pressure detection, because cushion block is provided with anti-rotation screw, guarantee that test splice does not rotate displacement in connection procedure, the manual propeller of leading screw replaces the artificial process that compresses test splice, and the two is connected closely to make the micro-water test splice of microwater device joint and SF6 air insulating device with anti-rotation cushion block cooperation, stressed even, have and be easy to carry, easy to operate, use safety, working efficiency is high, testing precision advantages of higher, alleviated greatly the wise labor intensity of doing workman.
