Abstract
The utility model relates to an insulating clamp used in electric power construction. Similar production in prior art have to cut a segment of an insulating layer of the wire to contact the clamp when using. Meanwhile, no insulating hood is arranged at the naked position on an insulating grounding ring pull, which is an unsafe factor when the line is working normally. The utility model is characterized in that an upper clamp and a lower clamp connected with each other are arranged in the casing of the insulating hood; a connecting hole is opened on the upper clamp and a contact block is connected with the upper clamp; an alloy conductor can be arranged on the insulating grounding pull ring and the insulating hood is arranged at the naked position of the pull ring. The utility model has the advantages of reasonable designed structure, convenient and reliable manufacturing, usage and assembling, safe operation, improved intensity of the wire and conductibility between the clamp and the conductor, and long service life.
Description
Technical field
The utility model relates to a kind of insulating clamp, particularly a kind of multifunction insulating wire clamp, and it is used a kind of insulation gold utensil in the construction of electric power system suspended insulated guide wire.
Background technology
Be the requirement that the reliability that satisfies urban distribution network power supply and the quality of power supply improve day by day, China has issued overhead insulation line (cable) designing technique rules, wherein lead, insulator, gold utensil etc. has been proposed requirement.As in lightning protection requires, pointing out, in, the low-voltage insulation distribution line in the interconnection switch both sides, divide pole, strain insulator knock-off joint place and might instead send on the lead of branch line point of electricity power failure working earthing point should be set, power failure working earthing point should be established insulating cover during the circuit operate as normal, and this point is generally finished by wire clamp.Its structure of insulating clamp of the prior art as shown in Figure 1 and Figure 2, must cut main traverse line 5 ' the preceding paragraph insulating barrier in use, main traverse line 5 ' is contacted with wire clamp, so not only reduced the intensity of lead, and can make rainwater infiltrate core in the lead exposed section, cause burning, influence electric conductivity; Simultaneously, there is unsafe factor in this wire clamp as power failure ground connection working point exposed section 10 ' naked cover (exposed section is charged) when the circuit operate as normal.2 ' is that insulation casing, 8 ' is insulation ground connection draw ring.
Summary of the invention
Technical problem to be solved in the utility model is the electric conductivity of guaranteeing between handling safety, increase lead intensity and wire clamp and conductor.
The technical scheme in the invention for solving the above technical problem is on the basis of existing insulated conductor, insulation casing, insulation ground connection draw ring and draw ring exposed section, is provided with wire clamp and drop wire clip in insulation casing, and this upper and lower wire clamp is connected.On last wire clamp, have wiring hole and be connected with contact block, on insulation ground connection T-Ring, can be provided with alloy conductor, and be provided with insulating cover in the draw ring exposed section.
The utility model also is provided with the insulation casing closure member, and it is enclosed in upper and lower wire clamp in the insulation casing.
Upper and lower wire clamp described in the utility model can be connected by cable clip bolt.
Insulating cover described in the utility model is a displaceable member, and it can move on insulation ground connection draw ring.
The utility model reasonable in design, manufacturing, use, easy installation and reliable, guaranteed workman's handling safety, the intensity of lead and the electric conductivity between wire clamp and conductor have been increased, simultaneously, long service life, function is many, can satisfy the reliability of urban distribution network power supply and the requirement that the quality of power supply improves day by day.
Description of drawings
Fig. 1, Fig. 2 are the structural representation of existing insulating clamp.
Fig. 3, Fig. 4 are structural representation of the present utility model.
Fig. 5 is an embodiment schematic diagram of the present utility model.
Embodiment
Referring to Fig. 3, Fig. 4, Fig. 5, the utility model mainly is made up of last wire clamp I, drop wire clip II, insulation casing 2, insulation ground connection draw ring 8 and insulating cover 9, upper and lower wire clamp I, II can be fixing by cable clip bolt 7, they all are positioned at insulation casing 2, and it is good with contacting of main traverse line 5 to guarantee to go up wire clamp I, drop wire clip II thus; Be provided with an insulating cover 9 movably in the draw ring exposed section 10 of insulation ground connection draw ring 8.
But the top of wire clamp I has the wiring hole 3 of a tap lead on the utility model, and institute's lead that connects can be fixing with bolt 1.The insulating barrier 6 of main traverse line 5 need not around exploitation, and the some that only need exploit contact block 4 gets final product, and like this, the influence of the pull-off force of main traverse line 5 is significantly reduced, and has promptly increased the intensity of main traverse line 5, the contact position is tight in addition, avoids the infiltration of rainwater; Contact block 5 can fuse with last wire clamp I, also can be installed on the wire clamp I.There are alloy conductor 11, its tip can puncture insulating barrier 6 in the interlocking of the upper end of the ground connection draw ring 8 that insulate and directly contact, to increase the electric conductivity between wire clamp and conductor with main traverse line 5.Insulation casing 2 coats upper and lower wire clamp I, II, and by 12 sealings of insulation casing closure member, installs very convenient.
When power failure work needs hanging earthing conductor, insulating cover 9 is removed, allowed earth connection (being the industrial siding of guaranteeing the work of electronics safety of workers during power construction) contact with draw ring exposed section 10 on the ground connection draw ring 8 that insulate.Work as end-of-job, during the circuit operate as normal (when switching on), mobile again insulating cover 9 covers the draw ring exposed section 10 of insulation ground connection draw ring 8, can guarantee safety thus.The utility model also can be adorned by lightning arrester as not adorning insulation ground connection draw ring 8, at this moment only needs the bolt that connects insulation ground connection draw ring 8 is pulled down, and lightning arrester is refilled to go up to drop wire clip II get final product.
In addition, also can not connect lightning arrester, connect the electric elements of other needs.
