Abstract
The utility model provides a kind of high voltage power cable multi-branch connector hold-down support of reliable performance, the installation for being related to cable connector when more high voltage power cables are tapped is fixed, its structure is that aperture penetrates at least three dry capacitor type insulation casings respectively in the side wall of shell, casing one end links together, and casting resin solidifies, sealing is integral, insulation between electrification in high voltage part and ground connection shell is undertaken by the higher dry capacitor type insulation casing of dielectric strength, the semi-conducting rubber stress wimble structure of abandoning tradition, there are preferable dielectric strength and mechanical strength.
Description
Technical field:
The utility model relates to carry out installation fixation to cable connector when more high voltage power cables are tapped.
Background technique:
With the rapid development in city, it is more and more general that high-power electric transmission is carried out to city using high voltage power cable
Time, power transmission is carried out as the mainstream between urban area using 110kv, 220kv high-tension cable in electric system.When electric power electricity
When cable carries out laying installation, it is often necessary to the case where You Yigen high-tension cable tap is at two, three or more multiple-limb.Many institutes
Known, the connector production of traditional high voltage power cable and in-site installation are all the very high work of technology content, and cost is high,
Even a simplest one-to-one transition joint, operator must strictly be operated by construction technology, moreover right
Two, one tapping structure for connecing three is connect in one, technical difficulty is bigger, and cost is also and its expensive.Initial stage in this century, China was for 110kv
And the one of ratings above power cable connector connects two structures, can't voluntarily manufacture, and need to be inflation from German import, structure
Formula, the price is very expensive, and a set of price needs more than 300 ten thousand yuan；In recent years, China part of the manufacturer started to develop 110kv
Power cable connector one connects the cable connector of two structures, also cries Y-shaped branch joint to replace import, so that the cost of connector is big
To reduce, wherein having a utility application 200820159084.3 is exactly a typical case.But this Y-shaped
In the structure of branch joint, when electrification in high voltage guide rod is pierced by from metallic ground shell, what is be pierced by from metallic ground shell is led
Electric pole fringing field intensity is very high, is simply provided between electrification guide rod and ground connection shell by semi-conducting rubber material in the case
Manufactured stress cone, to improve excessively high field strength problem, which has decrease to some degree local field strength and is evenly distributed with
Voltage effect, when overvoltage occurs in cable operation, the dielectric strength of this insulating Design structure is inadequate, and its be easy to cause electricity
The insulation of cable joint is breakdown.There are security risks.
Summary of the invention:
The purpose of the utility model is to provide a kind of high voltage power cable of reliable performance multi-branch connector hold-down support,
To solve the problems, such as the safe operation of high voltage power cable multi-branch connector.
In order to realize the purpose of utility model, the power cable multi-branch connector of reliable performance provided by the utility model
Hold-down support, aperture penetrates at least three prefabricated dry capacitor type insulation casings to housing sidewall respectively, the insulating sleeve
Conducting rod one end is linked together by electrical fitting, and the insulating sleeve is fixed by casing flange by bolt and shell, institute
The end shield for stating the capacitance plate of insulating sleeve is drawn to be electrically connected with casing flange, and housing cavity is solidified by sealing resin-cast, will
The insulating sleeve and electrical fitting sealing is integral, constitutes the main body of multi-branch connector hold-down support；The insulation sleeve
One end of pipe is equipped with the touch base being electrically connected with power cable, to connect with power cable reliable electric；The insulating sleeve
End be equipped with several uniformly distributed screw holes, in order to fixed power cable.
The outer surface of the shell external protrusion of the insulating sleeve point is equipped with multiple full skirts being made of insulating material, with
Increase electrification in high voltage position to the insulation creep distance between ground connection shell.
The high voltage power cable of reliable performance by adopting the above technical scheme multi-branch connector hold-down support, electrification in high voltage
Insulation between position and ground connection shell, is undertaken using the dry capacitor type insulation casing of prefabricated high insulation resistance, is insulated
Intensity and bending resistance tensile strength are better than traditional semi-conducting rubber stress wimble structure, and this design structure has abandoned traditional adopt
It uses insulating oil and insulating gas as the structure of major insulation, fundamentally solves the problems, such as that leakage bring is various, reliable performance,
It can be achieved non-maintaining.
In conclusion the utility model is that a kind of dielectric strength is high, bending resistance tensile property is excellent, site operation is convenient, property
It can reliable high voltage power cable multi-branch connector hold-down support.
Detailed description of the invention:
Attached drawing 1 is the structural schematic diagram of the utility model
In figure: 1. screw hole, 2. touch base, 3. full skirt, 4. dry capacitor type insulation casing, 5. capacitance plate, 6. casing flange 7.
8. sleeved conducting rod of shell, 9. electrical fitting, 10. sealing resin
Specific embodiment:
The utility model is further described with reference to the accompanying drawings and examples, what attached drawing provided is one to connect two schemes
Structural schematic diagram, the protection scope of the utility model is not limited to the present embodiment.
As shown in Figure 1, aperture penetrates at least three prefabricated insulation of dry capacitor type insulation casings 4 to 7 side wall of shell respectively
8 one end of conducting rod of casing 4 is linked together by electrical fitting 9, and insulating sleeve 4 passes through bolt and shell by casing flange 6
7 is fixed, and 5 end shield of capacitance plate of insulating sleeve 4 is drawn to be electrically connected with casing flange 6, and 7 inner cavity of shell is poured by sealing resin 10
Solidification, insulating sleeve 4 and electrical fitting sealing is integral, constitute multi-branch connector hold-down support main body；Insulating sleeve 4
One end be equipped with the touch base 2 that is electrically connected with power cable, to be connect with power cable reliable electric.The end of insulating sleeve 4
Portion is equipped with several uniformly distributed screw holes 1, in order to fixed power cable.The outer surface of 7 external protrusion of shell of insulating sleeve 4 point is set
There are multiple full skirts 3 being made of insulating material, to increase electrification in high voltage position to the insulation creep distance between ground connection shell 7.
