Abstract
The utility model discloses a kind of disc insulator protection caps; this kind of disc insulator protection cap includes cover board body, sealing bolt and seal washer; the flange portion of the cover board body is fixed by fastening bolt and disc insulator; at least provided with two detection holes on cover board body; the detection hole is threaded hole; detection hole has been connected through a screw thread sealing bolt, and the seal washer for sealing is cased on sealing bolt.By the above-mentioned means, the utility model structure is simple, convenient for the leak detection of disc insulator, avoid because remove cover board rear gas chamber internal pressure it is higher caused by disc insulator rupture and explosion.
Description
Technical field
The utility model relates to high pressure detection technique fields, more particularly to a kind of disc insulator protection cap.
Background technique
Disc insulator is very widely used in high-voltage switch gear at present, since high-voltage switch gear volume is big, it is impossible in work
Substation field is sent to after being all completed in factory, therefore high-voltage switch gear is exactly to be made of multiple and different gas chambers in design
, different gas chambers are sent to substation field in the form of multiple components after being installed in factory, complete again after reaching scene
General assembly, such as voltage transformer gas chamber and arrester gas chamber are exactly to be sent to substation field in a manner of single small gas chamber, then
General assembly is completed in substation field.
It between high-voltage switch gear difference gas chamber is separated with disc insulator, these small gas chambers are sent to inevitable when scene
Some disc insulators will expose in air, in order to avoid disc insulator makes moist and protects disc insulator from damaging,
Generally all a metal protection cover plate can be installed additional in the external of the disc insulator.
It will be exactly also in these small gas chambers by sealing leak test that these small gas chambers, which reach scene before the mounting,
Inner inflatable carries out comprehensive leak detection, including disc insulator direction gold to rated pressure to gas chamber after sealing when 24
Belong to the side of cover sheet, usually needs to remove metal coating lid when checking disc insulator towards metal protection cover plate side
Plate just will appear a problem at this time, because plenum interior is rated pressure, pressure is higher, as described in Figure 2 existing benzvalene form insulation
Sub- protection cap, as soon as the mounting flange that disc insulator after cover sheet just loses a metal is removed, at this time at disc insulator
In a unstable state, there is the risk for occurring to rupture and explode, is based on disadvantages described above and deficiency, it is necessary to existing technology
It is improved.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of disc insulator protection cap, structure is simple, is convenient for
The leak detection of disc insulator, avoid because remove cover board rear gas chamber internal pressure it is higher caused by disc insulator rupture and explosion.
In order to solve the above technical problems, the technical solution that the utility model uses is: providing a kind of disc insulator
Protection cap, this kind of disc insulator protection cap include cover board body, sealing bolt and seal washer, the flange of the cover board body
Portion is fixed by fastening bolt and disc insulator, and at least provided with two detection holes on cover board body, the detection hole is screw thread
Hole, detection hole have been connected through a screw thread sealing bolt, the seal washer for sealing are cased on sealing bolt.
Compared with prior art, the utility model has the beneficial effects that structure is simple, convenient for the leak detection of disc insulator,
Avoid because remove cover board rear gas chamber internal pressure it is higher caused by disc insulator rupture and explosion.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of disc insulator protection cap.
Fig. 2 is the structural schematic diagram of existing disc insulator protection cap.
Specific embodiment
The utility model preferred embodiment is described in detail with reference to the accompanying drawing, so that the advantages of utility model and spy
Sign can be easier to be readily appreciated by one skilled in the art, to make apparent specific boundary to the protection scope of the utility model
It is fixed.
Referring to Fig. 1, the utility model embodiment includes:
A kind of disc insulator protection cap, this kind of disc insulator protection cap include cover board body 1, sealing bolt 2 and close
The flange portion of seal washer 3, the cover board body 1 is fixed by fastening bolt and disc insulator 4, at least sets on cover board body 1
There are two detection hole 10, the detection hole 10 is threaded hole, and detection hole 10 has been connected through a screw thread sealing bolt 2, sealing bolt 2
On be cased with seal washer 3 for sealing.
When leakage test is done at scene, sealing bolt 2 is unscrewed manually, and the probe of leak detector is inserted into lid by detection hole 10
Whether 1 inside of plate ontology, detection disc insulator 4 leak, and sealing bolt 2 and seal washer 3 are fastened to inspection after leak detection
At gaging hole 10.
A kind of disc insulator protection cap of the utility model, structure is simple, convenient for the leak detection of disc insulator, avoids because tearing open
Except the higher caused disc insulator rupture of cover board rear gas chamber internal pressure and explosion.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
