Description
Technical field
The utility model belongs to cable joint, is a kind of new product on the domestic market, is specifically related to the separable single-phase cable three branch joint boxes of the underground mount type of 3X630A.
Background technology
The domestic used cable joint of cable branch box all is the products that adopt busbar one class of prefabricated at present, use the volume of cable branch box of this series products made big, it is attractive in appearance to influence the city, and the waterproof sealing performance of this series products when being installed in cable shaft or cable tunnel is relatively poor relatively, has destabilizing factor.
The utility model content
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and the separable single-phase cable three branch joint boxes of a kind of underground mount type that provide, use this product, not only can dwindle the volume of feeder pillar greatly, can also use as the cable end of underground installation simultaneously, comprise being installed in the cable shaft or cable tunnel or buried installation that its waterproof flood control performance is all very good.
The utility model is compared with the separable cable branch joint box of the underground mount type of three-phase, its benefit is the problem that has solved transportation well, and in addition, it is also convenient to install, as long as three separable cable branch joint boxes of single-phase underground mount type also get up to use, can satisfy the function of three-phase.Can also make full use of the distribution that the cable variety of way is satisfied in the space in addition.
The purpose of this utility model can realize by following measure:
The utility model comprises bus-bar, outer shielding layer, the epoxy resins insulation layer, the inner shield net, install and fix bolt, test point, two bus-bars connect, at the bus-bar skin epoxy resins insulation layer is set, at the epoxy resins insulation skin screen is set, the inner shield net in propping up, epoxy resins insulation is set, setting installs and fixes screw in the box body both sides, test point is set on box body, the connector box volume is very little, simultaneously, each branch in mutually couples together with bus-bar, and the cable joint of 630A is distributed on each face of connector box, be three-dimensional structure, allow the advancing of branch, outlet distributes obviously, install and distinguish convenience.Epoxide resin material is adopted in its insulation, and good electric insulating effect is arranged.Be built-in with the inner shield net, even internal electric field plays dual earth shield function with the outer shielding layer on surface, guarantees the safety of using.Test point can external electroscopy equipment, plays and can check at any time whether work is normal.In the both sides of cable-joint protector box, also be provided with and install and fix bolt, be convenient to install and fix.
The utility model has following advantage compared to existing technology:
The one, all insulation, full-shield, hermetically sealed.Tangible, the complete waterproof of product, corrosion-resistant is even under the abominable cable shaft of environmental condition, still can normally move.Product has very high security reliability; The 2nd, key component: branch's connecting box not only has hard indeformable good mechanical properties; and higher electric property arranged; also, make ground protection more reliable, can destroyedly do not arranged the longer life-span because of built-in earth shield simultaneously because of having unique inside and outside double shield ground connection.In addition,, form best connection combination again, make connection very reliable, after long-time running, can not stick together with being connected of rubber-like cable-to-cable connector; The 3rd, volume is little, and compact conformation has multiple combination, and product can satisfy the requirement in confined space installation and various bifurcation approach; The 4th, the utility model reasonable idea, modern design has bigger market potential.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to accompanying drawing 1-3, the utility model by bus-bar 1, outer shielding layer 2, epoxy resins insulation layer 3, inner shield net 4, install and fix bolt 5, test point 6 is formed, two bus-bars 1 connect, at bus-bar 1 skin epoxy resins insulation layer 3 is set, at epoxy resins insulation layer 3 skin screen 2 is set, 3 li inner shield net 4 is set at the epoxy resins insulation layer, setting installs and fixes screw 5 in the box body both sides, test point 6 is set on box body, the function of conduction, be communicated with by to be allowed three branches and realizes by being welded to connect by 2 bus-bars 1.With the mode moulding of epoxy resins insulation layer 3, reach the effect of electric insulation by cast.Dual shield ground connection by inner shield net 4 and outer shielding layer 2 makes ground protection more reliable, can destroyedly not arranged the longer life-span because of built-in earth shield 4 simultaneously; Whether normally passes through tested points 6 external electroscopy equipments can grasp power supply information at any time; When mounted, subsidiary mounting and fixing support can be fixed connector box by installing and fixing bolt 5, is secured on appointed positions or the facility by mounting and fixing support again, installs succinct, convenient.
With reference to accompanying drawing 4; the utility model and 630A T connector 7 are linked and packed by 630A bolt 8; cable comes 10 to be connected with the utility model with 630A T connector 7 by T type crimp type terminal 9 and American stress cone; another port of 630A T connector all comes shutoff with the American insulating plug of 630A under general situation; and cover its protective effect with the American insulating plug protective cover of 630A; but needing under the situation of multiple-limb; also can adopt the T-T ways of connecting to realize that usage is flexible and changeable by middle connector 11.When joint need keep and temporarily not use, can also it be sealed with insulator cap.
With reference to accompanying drawing 5, be the utility model and get up to make up schematic diagram, form by connector box 12, pad 13, nut 14, mounting and fixing support 15.
The utility model is mainly used in the occasion that 10-35kV power cable system needs multiple branches, can be directly installed in underground cable well, the cable tunnel.The utility model is the branch joint of 630A entirely, when being used for underground installation, can substitute the overground cable feeder pillar fully, especially the occasion that in the urban network reconstruction engineering, needs multiple branches, can be used in combination with ring main unit, be applied on the tie-point of looped network or on the breakout of looped network branch line end and can provide and reserve branch's (when reserving branch, corresponding reserved location on branch's connecting box must seal it with insulator cap).Use this utility model not only can improve the security reliability of power supply, also can save the investment of relevant device and cable, and the purifying city space, beautify the environment.
