Technical field
The utility model relates to a kind of Multifunctional casing end shield wire clamp, relates in particular to a kind of Multifunctional casing end shield wire clamp of copper material, belongs to electric system High-Voltage Experimentation Technology field.
Background technology
The bottom shielding of bushing structure mainly contains 3 kinds of forms, such as accompanying drawing 2 direct contact types, Fig. 3 spring leaf interconnection system, the built-in grounding type of Fig. 4.Bottom shielding of bushing needs ground connection when operation; When measuring sleeve pipe shelf depreciation, end shield insulation against ground resistance and the high pressure such as dielectric loss, sleeve body dielectric loss is tested over the ground, need to throw off end shield stem grounding connection, end shield stem and ground are insulated to make things convenient for carrying out of high-potting.For Fig. 2 direct contact type and Fig. 3 spring leaf interconnection system end shield structure, behind the ground connection of the outwarding winding lid end shield stem is thrown off and be connected with ground; But for the built-in grounding type end shield of Fig. 4 structure, after opening protecting cover, the end shield stem still keeps ground state, need tool using that the ground sleeve top of end shield stem is depressed into below the spacing hole, then in spacing hole, insert metallic pin and be fixed, stem is thrown off with ground fully be connected.
For Fig. 2 direct contact type and Fig. 3 spring leaf interconnection system end shield structure, can adopt common wire clamp to carry out wiring during test.For the built-in grounding type structure of Fig. 4, need to push ground sleeve inward with pliers or flat mouth cone etc. during test and then in spacing hole, insert metallic pin, carry out wiring with common wire clamp more afterwards; Need to push away ground sleeve inward then from spacing hole with pliers or flat mouth cone etc. when testing complete recovery and take out metallic pin, unclamp ground sleeve, ground sleeve top outward under the effect of spring, thus recover being connected of stem and ground.In the operation when actual tests, make the ground sleeve unbalance stress that bite occur because adopting pliers or flat mouth cone etc., especially easily cause stem unearthed at the ground sleeve bite that test is complete when recovering, thereby cause that the end shield discharge that is in operation causes the sleeve pipe fault; On the other hand because adopting pliers or flat mouth cone etc. to make the ground sleeve unbalance stress, can make that stem is stressed and crooked to be rocked, the sealing of destructible stem root or stem occurs fracture; The metallic pin that is used in conjunction with spacing hole mostly is temporarily draws materials, and its size is less easily loses, and brings inconvenience to test.
Summary of the invention
The utility model is the inconvenience when overcoming the existing built-in grounding type end shield of bottom shielding of bushing Fig. 4 structural test just, and the facility when taking into account Fig. 2 direct contact type and Fig. 3 spring leaf interconnection system end shield structural test, the utility model provides a kind of Multifunctional casing end shield wire clamp, this multi-functional wire clamp not only uses when the built-in grounding type end shield of Fig. 4 structural test, and can use in Fig. 2 direct contact type and Fig. 3 spring leaf interconnection system end shield structure.
The utility model adopts following technical scheme to realize.
A kind of Multifunctional casing end shield wire clamp, the utility model is characterised in that: comprise the upper jaw and the lower jaw section, torsionspring and be connected the up and down spring legs that the upper jaw and the lower jaw roller pin is connected with torsionspring; Circular configuration is adopted in the cross section of described the upper jaw and the lower jaw section, adopt teeth to mesh up and down in jaw section; Offer the corresponding metallic pin jack in position in the upper jaw and the lower jaw section, offer the corresponding fixed orifice in position at described up and down spring legs afterbody; And a described fixed orifice is connected with metallic bond therein; The metallic bond termination is fixed with the metallic pin that matches with the metallic pin jack; Another described fixed orifice is used for the fixed outer electric wire; Cover has insulating gum cover respectively on spring legs up and down.
The utility model is except insulating gum cover, and whole Multifunctional casing end shield wire clamp adopts copper material.
The utility model beneficial effect is, the utility model adopts circular jaw section wire clamp, can rely on circular end surface to make the ground sleeve in the built-in grounding type end shield of Fig. 4 structure stressed evenly, presses on the top with discharging in the ground sleeve process and can effectively avoid occuring crooked and bite; The utility model wire clamp afterbody one fixed orifice adopts metallic bond to be fixed with the cylinder type metal pin, can when being depressed into the metallic pin jack and overlapping with end shield stem spacing hole by the top, insert wherein ground sleeve, metallic bond can effectively prevent the loss of metallic pin, and the insertion that makes things convenient for metallic pin with extract.
For Fig. 2 direct contact type and Fig. 3 spring leaf interconnection system end shield structure, the utility model Multifunctional casing end shield wire clamp can rely on jaw section from end shield stem clamp end shield stem radially, also can rely on circular jaw section from the axial direct clamp stem of end shield stem.
The utility model Multifunctional casing end shield wire clamp has easy and simple to handlely, and practical reliably characteristics generally are applicable in the various bottom shielding of bushing structures fault or the damage that can effectively avoid end shield to cause because of operation.
