Description
Technical field
The utility model belongs to the device of a kind of cable metal cover impermeability test in cable testing apparatus technical field.
Background technology
Along with the progress of society and the development of science and technology; the industry requirement such as electric power, communication amount grows with each passing day; especially high pressure and extra-high-tension cable all adopt metallic sheath to play sealing, waterproof and shielding action as the screen layer of cable; and clear stipulaties cable metal cover impermeability test requires as inflation 0.4MPa ± 0.01MPa; lasting 2 hours constant; so that better protect the safe operation of insulated wire cores, thus also more and more higher to the technical requirement of cable metal cover leak tightness test device.In known technology; the pressurized with compressed air pressure test device that existing cable metal cover leak tightness test device mainly adopts; but limit by its structure; its structure is complicated; often can cause in practical application pouring the safety that wet gas jeopardizes cable body; again because cable packaging size is normally not less than 3.2 meters; weight is not less than 8 tons; aerating device is fixed on a place and is unfavorable for operation; wasting manpower and material resources; and rain glass is put arbitrarily and is caused error of test data large, also causes inconvenience to actual tests work.
Utility model content
In order to overcome the deficiencies in the prior art, solve existing cable metal cover leak tightness test device structure complicated, the problem that actual tests error is large.The object of the utility model is to provide a kind of simple and practical, and test figure is accurate, saves labor, Novel cable metallic sheath leak tightness test device easy to use.
The technical scheme in the invention for solving the above technical problem is:
A kind of cable metal cover leak tightness test device, it is provided with: body, panel, nitrogen cylinder, operation valve, rain glass, tracheae, outgoing gas connection tube, body is the body of the triangle body of foot wheel, the triangle body skewback of body is fitted with on nitrogen cylinder, right-angle side side plate and is equiped with panel, panel is fitted with operation valve, rain glass, the intake interface of operation valve connects the mouth of pipe of giving vent to anger of nitrogen cylinder by tracheae, gas interface is fitted with the outgoing gas connection tube connecting standby detection streamer, and on outgoing gas connection tube, is equiped with 1-2 block rain glass.
Above-mentioned cable metal cover leak tightness test device the control panel of described body and institute's load is be fitted with 1-4 to overlap the cable metal cover impermeability test unit combination body be linked to be by nitrogen cylinder, operation valve, rain glass, tracheae and outgoing gas connection tube institute group.
The above-mentioned cable metal cover leak tightness test device stated, described rain glass is all ranges is 0 ~ 1kPa, precision is the rain glass of 0.01.
When the utility model uses, according to designing requirement, after this novel cable metal cover leak tightness test device is pushed to desired location, ammonia test code testing operation can be carried out at outgoing gas connection tube to connecting cable to be tested.
Because the utility model design have employed technique scheme, efficiently solve existing cable metal cover leak tightness test device structure complicated, the problem that actual tests error is large.Also show through carrying out several test result on trial, the advantages such as it has simple and practical, and test figure is accurate, saves labor, convenient to use, are applicable to the metallic sheath impermeability test of various high pressure and extra-high-tension cable.
