Abstract
The utility model provides high T type cable head convenient to high -voltage testing, including " F " type metallic structure, the outer cladding insulation screen of " F " type metallic structure is as the shell, and the lower extreme of " F " type metallic structure's montant is the cable crimping head, and " F " type metallic structure's first horizontal pole is as the conducting rod, and " F " type metallic structure's second horizontal pole is as the high -voltage testing pole, the opposite side installation arrester relative with the conducting rod, the high -voltage testing pole stretches out outside insulation screen, and the metal ellipsoid is connected to the outer end of high -voltage testing pole, and wireless temperature sensor is still installed to metal ellipsoid overcoat resilient insulating rubber sleeve on the shell that insulation screen constitutes. The utility model discloses can directly measure with high -voltage testing clamp centre gripping metal ellipsoid, it is convenient to measure.
Description
Technical field
The utility model relates to a kind of T-shaped cable end, belongs to cable splice technical field.
Background technology
In high voltage power transmission process, the connected mode of the T-shaped cable end of the many employings of high-pressure side cable end, have full-shield, all insulation, hermetically sealed, charged tangible, ensure that the personal safety of attended operation personnel, the equipment operational reliability of making improves greatly.Normally annual when doing preventative high-potting, T-shaped cable end is all needed to untie, lightning arrester part and T-shaped cable end part are untied, high-potting clamp could be connected with cable end conducting rod left part to be tested, because T-shaped cable end internal diameter is little and long and narrow, high-potting clip contact less than, this working routine is loaded down with trivial details, require meticulous, also to reinstall after off-test, waste time and energy and in disassembly process, easily cause the stressed excessive generation loose contact of cable end line ball nasal portion, very easily causing the overheated scaling loss of cable end in the future.In order to carry out high-potting to T-shaped cable end, the scheme of mounting spring or hollow circular-tube on the conducting rod that CN204575686U has technology to be disclosed in T-shaped cable end, but this mode needs the shape of this change conducting rod interface portion, because conducting rod is tiny, requirement on machining accuracy is high, and mounting spring or hollow circular-tube do not have certain technical difficulty.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of T-shaped cable end being convenient to high-potting, and the design for electrical conductors of its T-shaped cable end becomes " F " type metal construction, and connects and draw a metal ellipsoid for high-potting, test is convenient, simple to operate.
The utility model is realized by following technical proposals.A kind of T-shaped cable end being convenient to high-potting, comprise " F " type metal construction, " F " type metal construction outer cladding insulation screen is as shell, the lower end of the montant of " F " type metal construction is cable crimp head, first cross bar of " F " type metal construction is as conducting rod, and the second cross bar of " F " type metal construction is as high-potting bar; The opposite side zinc oxide surge arresters relative with conducting rod, high-potting bar extend out to outside insulation screen, the outer end connection metal ellipsoid of high-potting bar, the elastic insulated rubber sleeve of metal ellipsoid overcoat.
Further improvement, the shell that insulation screen is formed installs radio temperature sensor.
Described insulation screen is that ethylene propylene diene monomer (EPDM) material is made.
The utility model is provided with metal ellipsoid for high-potting on the basis of the T-shaped cable end of tradition, can directly measure with the clamping of high-potting clamp, measuring speed is fast, simple to operate, and effectively prevent the stressed excessive generation loose contact of cable end, and radio temperature sensor measuring tempeature is set, timely monitoring, reacts in time, prevents the overheated scaling loss of cable end, improve work efficiency, reduce maintenance cost.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
1. insulation screen 2. radio temperature sensor 3. lightning arrester 4. " F " type metal construction 5. conducting rod 6. elastic insulated rubber sleeve 7. metal ellipsoid 8. high-potting bar 9. cable crimp head in figure.
Embodiment
As shown in Figure 1, this T-shaped cable end, comprise " F " type metal construction 4, " F " type metal construction outer cladding insulation screen 1 is as shell, the lower end of the montant of " F " type metal construction 4 is cable crimp head 9, first cross bar of " F " type metal construction 4 is as conducting rod 5, and the second cross bar of " F " type metal construction 4 is as high-potting bar 8; The opposite side zinc oxide surge arresters 3 relative with conducting rod 5, high-potting bar 8 extend out to outside insulation screen 1, the outer end connection metal ellipsoid 7 of high-potting bar 8, the elastic insulated rubber sleeve 6 of metal ellipsoid 7 overcoat.
During high-potting, directly take off elastic insulated rubber sleeve 6, can directly measure with high-potting clamp clamping metal ellipsoid 7, it is convenient to measure.Why ellipsoid shape being arranged in measuring point, is that ellipsoid shape can avoid the situation of loose contact to occur to greatest extent because the jaw of high-potting clamp is generally also in ellipse shape.
In order to monitor the temperature of T-shaped cable end, preventing from burning out, also on the shell of insulation screen 1 formation, radio temperature sensor 2 being installed, for measuring tempeature.
Described insulation screen 1 is that ethylene propylene diene monomer (EPDM) material is made, its good insulation preformance.
More specifically, the lower end of the shell that insulation screen 1 is formed extends to cable crimp head 9 direction, and form cable insert port, right-hand member extends to conducting rod 5 direction and forms interface slot, the additional gland bonnet of interface slot; The left end of the shell that insulation screen 1 is formed extends left and connects lightning arrester 3, and the housing integration that insulation screen 1 is formed is T-shape.
Claims (3)
1. be convenient to the T-shaped cable end of high-potting for one kind, it is characterized in that: comprise " F " type metal construction, " F " type metal construction outer cladding insulation screen is as shell, the lower end of the montant of " F " type metal construction is cable crimp head, first cross bar of " F " type metal construction is as conducting rod, and the second cross bar of " F " type metal construction is as high-potting bar; The opposite side zinc oxide surge arresters relative with conducting rod, high-potting bar extend out to outside insulation screen, the outer end connection metal ellipsoid of high-potting bar, the elastic insulated rubber sleeve of metal ellipsoid overcoat.
