Abstract
The invention relates to a binding film for leakage detection of sulfur hexafluoride electric equipment, which comprises a plastic layer, a double-sided sticky tape and a plastic film. The binding film for leakage detection of sulfur hexafluoride electric equipment is characterized in that cylindrical plastic bodies are uniformly distributed and vertically prepared on an upper plane of the plastic layer at intervals; the double-sided sticky tape is spliced and fixedly arranged on the lower plane of the plastic layer; and the plastic film is spliced and fixed with the lower plane of the double-sided sticky tape. After the binding film provided by the invention is bound, a regular geometrical shape is formed; a clearance between the binding film and a detected part is a fixed value; and a binding cavity volume and a yearly air leakage rate of an air chamber are accurately calculated, so that the leakage condition of the air chamber is accurately judged and the unnecessary power-off overhaul caused by misjudgment and the unscheduled power outage caused by accident air leakage of the air chamber are avoided. The binding film provided by the invention has the advantages of low cost of raw materials, convenience in use and obvious economic and social benefits.
Description
Technical field
The invention belongs to electric system high-tension switch gear detection range, particularly relate to a kind of sulfur hexafluoride electrical equipment leak detection wrapping film.
Background technology
Relatively year leak rate be that the sulfur hexafluoride gas-insulating high-tension switch gear dispatches from the factory, one of the important technology index of Bidding Invition and examination, also be the major criterion of support equipment safe and stable operation.The large-scale switchgear of accomplishing to assembled on site at present, quantitative leak uses most often local bandaging strapping.Carry out part wrapping and leak detection according to 4.2.3 bar in the standard (GB/T11023-1989); Employed plastic sheeting is varied, and the geometric configuration that wrapping forms is irregular, space heterogeneity between plastic sheeting and the test specimen; Wrapping chamber inner volume can only be estimated; The year leak rate error that calculates is very big, and the leak detection accuracy is difficult to satisfy the needs of arbitration, and the normal generation dispute on the problem whether the equipment leak rate exceeds standard of each power supply unit and producer.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of sulfur hexafluoride electrical equipment leak detection wrapping film is provided.
The present invention solves its technical matters and takes following technical scheme to realize:
A kind of sulfur hexafluoride electrical equipment leak detection wrapping film; Comprise plastic layer, double sticky tape, plastic sheeting; The plane is uniformly distributed with at interval and vertically is shaped on cylindric plastic body on plastic layer, at the bonding double sticky tape that installs of the bottom surface of plastic layer, and the bonding plastic sheeting that installs of the bottom surface of this double sticky tape.
And the thickness of said plastic layer is 0.2-0.5mm; The height of said cylindric plastic body is 5-20mm, and diameter is 2-5mm, and the spacing between each cylindric plastic body is 20-50mm; The thickness of said plastic sheeting is 0.05-0.2mm.
Advantage of the present invention and good effect are:
1, the present invention meets " high-tension switch gear sulfur hexafluoride gas leakage test method " (GB/T11023-1989) for the standard-required of part wrapping leak test method.
2, the geometric configuration of formation rule behind the designed special wrapping film bundling, and the gap between the test specimen is a fixed value, but accurate Calculation wrapping cavity volume and air chamber year leak rate.
3, plastic layer of the present invention is according to the size of test article, and shape and the scene is cut into different size makes special-purpose wrapping film be close to test specimen with the fixed interval (FI), thereby accurately calculates the volume in wrapping chamber, improves the practicality and the reliability of wrapping film.
4, the special-purpose wrapping of the present invention thin film fabrication material requested is cheap, convenient to use.
But 5, use film bundling leak detection accurate Calculation air chamber year leak rate of the present invention; Thereby judge that accurately air chamber leaks situation; The unplanned property power failure of avoiding misjudgment to cause unnecessary maintenance power failure and air chamber accidental gas leakage to cause has remarkable economical and social benefit.
Description of drawings
Fig. 1 is a structural front view of the present invention;
Fig. 2 is the enlarged drawing of looking up of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is done further detailed description:
A kind of sulfur hexafluoride electrical equipment leak detection wrapping film; Shown in Fig. 1 and 2; Comprise plastic layer 1, double sticky tape 3, plastic sheeting 4; The plane is uniformly distributed with at interval and vertically is shaped on cylindric plastic body 2 on plastic layer, at the bonding double sticky tape that installs of the bottom surface of plastic layer, and the bonding plastic sheeting that is fixed with of the bottom surface of this double sticky tape.
Embodiment 1:
The thickness of selecting plastic layer for use is 0.2mm, cylindric plastic body diameter 2mm, and height 5mm, the spacing between each cylindric plastic body is 20mm, the thickness of plastic sheeting is 0.05mm.According to the shape of parts to be tested, the size of cutting plastic layer splices and the corresponding shape of parts to be tested, through double faced adhesive tape plastic sheeting is pasted on plastic layer plane one side then and forms integral body, calculates the plastic layer whole surface area.Towards parts to be tested, each cylindric plastic body top all closely contacts with parts to be tested with the cylindric plastic body of plastic layer, and plastic layer wraps up parts to be tested, and the parcel seam crossing is used rubber belt sealing.Through plastic layer whole surface area and cylindric plastic body height, calculate the volume in the parcel cavity, this volume deducts the volume of all cylindric plastic bodies of inside cavity, obtains wrapping up the volume of gas in the cavity.After the sealing of parcel cavity is accomplished, behind specified time interval, pierce through integument, the gas in the parcel cavity is carried out sulfur hexafluoride gas concentration detect.Each sealing surface of sulfur hexafluoride air cell is carried out above-mentioned local wrapping leak detection just can accurately calculate this air chamber year leak rate relatively.
Embodiment 2:
The thickness of selecting plastic layer for use is 0.5mm, cylindric plastic body diameter 5mm, and height 20mm, the spacing between each cylindric plastic body is 50mm, the thickness of plastic sheeting is 0.2mm.According to the shape of parts to be tested, the size of cutting plastic layer splices and the corresponding shape of parts to be tested, through double faced adhesive tape plastic sheeting is pasted on plastic layer plane one side then and forms integral body, calculates the plastic layer whole surface area.Towards parts to be tested, each cylindric plastic body top all closely contacts with parts to be tested with the cylindric plastic body of plastic layer, and plastic layer wraps up parts to be tested, and the parcel seam crossing is used rubber belt sealing.Through plastic layer whole surface area and cylindric plastic body height, calculate the volume in the parcel cavity, this volume deducts the volume of all cylindric plastic bodies of inside cavity, obtains wrapping up the volume of gas in the cavity.After the sealing of parcel cavity is accomplished, behind specified time interval, pierce through integument, the gas in the parcel cavity is carried out sulfur hexafluoride gas concentration detect.Accurately calculate a year leak rate.
