Abstract
The invention discloses a crosslinked cable tail end metal end enclosure sealing tester, which belongs to the field of electric wire and cable test. The tester consists of an outer frame and an ejecting mechanism. The outer frame consists of an upper baffle plate, a lower baffle plate and pulling rods, wherein the upper baffle plate is arranged at one end of the pulling rods; the lower baffle plate is arranged on the other end of the pulling rods; the two ends of the pulling rods are positioned by nuts; and the pulling rods are distributed on the upper and lower baffle plates uniformly. The ejecting mechanism consists of a gland, a lower backing ring and an ejecting rod, wherein the lower backing ring is arranged on the lower baffle plate; the ejecting rod is arranged on the gland and passes through the upper baffle plate; and the gland is arranged below the upper baffle plate. The gland is provided with an air hole in which a quick coupling connected with an air pipe is arranged. The tester is reasonable in design, good in effect and high in efficiency and can realize quick tests.
Description
Technical field
Crosslinked cable tail end metal end enclosure sealing tester of the present invention belongs to the electric wire detection range, is mainly used in the leakage pressure testing device of testing to finished product crosslinked cable packing end socket annex.
Background technology
In the production and work progress of cable, waterproof strict will make the cable water inlet accidentally if handle.The harm of cable water inlet can be described as very serious.After the cable water inlet, under effect of electric field, water tree aging phenomenon can take place, cause cable breakdown at last.The water tree is that diameter is gathered to several microns water-filled spaces at 0.1 μ m, and the local high electric field position that the inhomogeneous place of the impurity that exists in the insulation, pore and insulation and interior outer semiconducting layer faying face forms is the starting point that the water tree is taken place.The evolution of water tree is generally more than 8 years, and humidity is high more, and temperature is high more, and voltage is high more, and contained ion is many more in the water, and then the development of water tree is fast more.For preventing into water, before product export, to pack treatment process and just can deliver goods through strict.Wherein head end and tail end all will be joined and made the respective metal end socket.The main composition of tail end end socket is two-layer sheath, and nexine is to be welded into whole aluminium end socket with aluminium sheath, and skin is socketed on the plastics oversheath with the pyrocondensation big envelope.Metal end enclosure is last one barrier that prevents crosslinked core water inlet.And the effect that runs into mechanical external force through regular meeting in actual cable installation process makes the breakage of pyrocondensation end socket, if metal end enclosure have pore or with sheath be welded with defective the time, the core water inlet just is difficult to avoid.Along with the large tracts of land use of power cable with cross-linked polyethylene insulation in recent years, but the production standard and the method for inspection of the concrete metal end enclosure of being correlated with (containing the tail envelope), there is not suitable crosslinked cable tail end metal end enclosure sealing tester yet, therefore metal end enclosure brings more serious quality to draw trouble to cable because the workpiece casting process is easy to generate pore and crackle.
Summary of the invention
The object of the present invention is to provide a kind of efficient height, simple and convenient, check crosslinked cable tail end metal end enclosure sealing tester fast.
The objective of the invention is to reach by following measure, the present invention is made up of outside framework and top-pressure mechanism, and outside framework is by overhead gage, lower baffle plate, pull bar is formed, and overhead gage is installed in pull bar one end, lower baffle plate is installed in pull bar one end, and locate by nut at the pull bar two ends, and pull bar is distributed on overhead gage and the lower baffle plate, top-pressure mechanism is by gland, following backing ring, and push rod is formed, following backing ring is installed on the lower baffle plate, push rod is installed on the gland, and push rod passes overhead gage, and gland is arranged on below the overhead gage.Gland is provided with pore, and rapid-acting coupling is installed on pore, and rapid-acting coupling connects tracheae, and tracheae passes overhead gage.
Push rod of the present invention and gland are installed on the gland by straight pin, between push rod and gland steel ball are set and are connected, and increase the work contact area.
Gland of the present invention top welding register pin, register pin passes overhead gage, can prevent that gland from rotating.
Push rod of the present invention is provided with screw thread, and screw is arranged on the overhead gage, and the screw thread of push rod cooperates with screw on the overhead gage.
The uniform support of pull bar of the present invention, upper and lower baffle plate bears stretching action power.Top-pressure mechanism carries out downward roof pressure gland by the thrust of push rod, makes workpiece and gland form sealing.During operation, workpiece is placed on the backing ring, compresses gland by push rod, and gland makes sealing gasket and workpiece openings position form seal face under the roof pressure of acting force, and workpiece inside has constituted airtight " cavity "; In " cavity " of workpiece, add compressed nitrogen by the rapid-acting coupling that is fastened on the gland top; Whether the inflation workpiece is together put into water together with sealer observe and to have steam bubble to emerge, as do not have then that workpiece is qualified workpiece, emerging if any steam bubble then can perform sign in bubbling place, carries out corresponding repair by welding work then.
The present invention is reasonable in design, and is respond well, and the efficient height can be realized fast detecting.
