Abstract
The invention provides an insulating protective jacket, which can be used at electric joints of distribution equipment such as a cable branching box, a switch cabinet, a ring-network cabinet and the like. The insulating protective jacket is characterized in that the insulating protective jacket comprises a housing and an enclosing passage adapted to a member wrapping an electric joint inside the housing; and the housing adopts integrated structure made of an insulating material.
Description
Technical field
The present invention relates to insulating protection accessory, particularly insulating sheath in the grid equipment, it can use the place that is electrically connected at equipment for power transmission and distribution such as cable branch box, switch cubicle, ring main units.
Background technology
In urban network reconstruction, need a large amount of equipment for power transmission and distribution such as cable branch box, switch cubicle, ring main unit that use, therefore also more and more higher to the property safe and reliable to operation requirement of these equipment.The turnover line cap place of original cable branch box, switch cubicle, ring main unit and with the place that is electrically connected of busbar, if directly expose in air, easily assemble dust, in a humid environment, for example in the more southern areas of China, easily form condensation, these factors all can reduce the insulation property of product.Prior art generally adopts dressing type or claims wound form, the insulating tape wrapping is easily being formed condensation and is easily assembling the place of dust, but wasting time and energy complex operation, labor and raw material's cost height.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of insulating sheath is provided, it can use the place that is electrically connected at equipment for power transmission and distribution such as cable branch box, switch cubicle, ring main units.
Series technical project of the present invention is as follows:
Insulating sheath is characterized in that: comprise adapting to the suit passage that parcel is electrically connected place's member in housing and the housing, described housing is for adopting the integrative-structure of insulating material.
Described insulating material adopts silastic material.
Described suit passage comprises main channel and subchannel, is communicated with by choke between described main channel and the subchannel.
The axial line of described main channel overlaps with the axial line of subchannel.
The axial line of described main channel and the axial line of subchannel are T-junction.
Described subchannel has two, is dislocatedly distributed up and down in the both sides of main channel.
Technique effect of the present invention: the present invention is a reinforced insulation, according to the profile that is electrically connected the place, the insulating part that is wrapped in the place of being electrically connected is designed to the suit passage of integrative-structure, its suit passage closely cooperates with the place of being electrically connected, both played the effect of reinforced insulation, be convenient to again simultaneously install, time saving and energy saving; With the suit channels designs is main channel and subchannel structure so that and be electrically connected place's better fit, main channel and subchannel are communicated with by choke, have increased thickness of insulating layer, have guaranteed better insulating properties; Housing adopts silicon rubber as insulating material, and electrical insulation capability is good, has high resiliency, has the anti-condensation performance of good waterproof simultaneously, high temperature resistant low temperature, the difficult be full of cracks.
Description of drawings
Fig. 1 be insulating sheath embodiment of the present invention-structural representation.
Fig. 2 is the structural representation of insulating sheath embodiment two of the present invention.
Fig. 3 is the structural representation of insulating sheath embodiment three of the present invention.
Reference numeral lists as follows:
The 1-housing, 2-suit passage, 3-choke, 4-subchannel, 5-main channel.
Embodiment
Fig. 1 is one embodiment of the present of invention-insulating sheath, be used to be installed in the end of incoming cables of switch, comprise housing 1, suit passage 2, adopt the silastic material one-shot forming to make integrative-structure, suit passage 2 is divided into subchannel 4 and main channel 5, main channel and subchannel axial line overlap, the main channel is the cylinder of hollow, the subchannel is the round platform that certain taper is arranged of hollow, the tapering of tapering and switch sleeve pipe is complementary, main channel and subchannel are communicated with by choke 3, and choke and switch cover external diameter of pipe are suitable.During use, insulating sheath vertically is installed on the switch sleeve pipe gets final product.
Fig. 2, Fig. 3 are two the embodiment-insulation threeway protective jackets in addition of the present invention and the four-way protective jacket that insulate, and are used to be installed in the junction of busbar and switch.Fig. 2 is the structural representation of insulation threeway protective jacket, comprise housing 1 and suit passage 2, adopt the silastic material one-shot forming to make integrative-structure, main channel and subchannel axial line are T-junction, main channel 5 is enclosed within on the switch, be shaped as the round platform of hollow, the tapering and the bore of tapering and bore and switch sleeve pipe are complementary, busbar penetrates in the main channel 5 by subchannel 4, subchannel 4 is the cylinder of hollow, bore and busbar bore are complementary, and connected component passage 4 is designed to the bottleneck shape with the choke 3 of main channel 5.
Fig. 3 for insulation four-way protective jacket structural representation, different with the insulation threeway is two subchannels 4 about the insulation four-way has, and two subchannel axis are not point-blank, stagger the mutually diameter of a busbar, busbar can be superimposed with each other after penetrating main channel 5 from subchannel, the left and right sides.
Should be pointed out that the above embodiment can make those skilled in the art more fully understand the invention, but do not limit the present invention in any way creation.Therefore, although this specification has been described in detail the invention with reference to drawings and Examples,, it will be appreciated by those skilled in the art that still and can make amendment or be equal to replacement the invention; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of the invention, and it all is encompassed in the middle of the protection range of the invention patent.
