Existing Multi-function pliers for high-altitude connecting wire; be mainly used in the substation equipment maintenance and repair of electric power system; carry out contact resistance, loop resistance, relaying protection CT test etc. electric equipment is carried out to high-altitude wiring test; be particularly suited on ground in the face of altitude plant detects wiring; by pushing away, draw operating arm dedicated; can make jaw free-open-close, complete wiring work.
But for the high-altitude wiring of 500kV capacitance type potential transformer, because conventional overhead jointing clamp jaw Breadth Maximum is 6cm, the minimum thickness of the metal flange (wiring position) of 500kV capacitance type potential transformer reach 8cm and more than, therefore common multifunctional overhead jointing clamp cannot be applied to the high-altitude wiring of 500kV capacitance type potential transformer.
Summary of the invention
For the not enough problem existing of existing overhead jointing clamp width of jaw, the utility model provides a kind of novel high-altitude wiring clamp device for carrying out the test connection of 500kV capacitor voltage transformer, this high-altitude wiring clamp device has solved the problem that original overhead jointing clamp width of jaw deficiency cannot wiring, staff can be operated on the ground, the risk of having avoided work high above the ground to fall, has improved efficiency and safeguard work personnel's safety.
The preventive trial project of 500kV capacitance type potential transformer comprises tan δ and the electric capacity measuring of insulation measurement, capacitor.Because 500kV capacitance type potential transformer is generally in series by three to four economize on electricity container components, the each capacitor element of independent measurement need to have different mode of connections.
Research how to carry out better in test connection process, we find, p-wire is all on the metal flange being connected between each capacitor element, carries out the input of voltage and the sampling of signal with this.
To achieve these goals, the utility model provides a kind of 500kV capacitance type potential transformer high voltage test jointing clamp device, comprise the arc-shaped elastic metal pliers of the metal flange wiring position that clamps tight 500kV capacitance type potential transformer, arc-shaped elastic metal pliers card is around metal flange, the jaw of arc-shaped elastic metal pliers is unenclosed construction, and arc-shaped elastic metal pliers is provided with increases contact-making surface and the flexible tension spring of wiring; Also include the high-altitude insulation junction pole being connected with arc-shaped elastic metal pliers.In administered 500kV transformer station, 500kV capacitance type potential transformer is column type form of flanges, conventional jointing clamp adopts stretching form, width of jaw is inadequate, can not fixedly contact with flange, therefore, adopt arc-shaped elastic metal pliers as wiring setting tool, can block around metal flange, be fixed and sample.The arc-shaped elastic metal pliers that adopts metal material to make, can carry out good docking with the metal flange of column type, completes test connection requirement.
Further, the wire coiling that described arc-shaped elastic metal pliers is 5mm by diameter forms, and the jaw both ends of arc-shaped elastic metal pliers are all to the formation flange that turns up.Make arc-shaped elastic metal pliers with wire and replace traditional hooking to make fixed form, flange design can improve stability and the operability of wiring, can increase again contact-making surface, improves the elasticity of arc-shaped elastic metal pliers; And before contacting with metal flange, jaw unenclosed construction can more easily carry out contraposition.
Further, described tension spring is provided with 4 and is all arranged in order the inner side that is distributed in arc-shaped elastic metal pliers.Tension spring has increased the contact dynamics of arc-shaped elastic metal pliers with metal flange.
Further, described arc-shaped elastic metal pliers connected with being connected by contiguous block of high-altitude insulation junction pole, and contiguous block is can put forward contact effect tip-shape towards the top of a side of arc-shaped elastic metal pliers.Adopt tip-shape replacement flat contact surface, improve contact effect.Plane contact may occur that plane is unsettled, does not form contact point with metal flange.Meanwhile, the paint on metal flange, dirty, oxide etc. also can affect test result.And adopt tip-shape some contact, can effectively avoid above-mentioned situation.
Further, the insulating bar that described high-altitude insulation junction pole is telescopic structure.Because the device body of 500kV capacitance type potential transformer is higher, will be very heavy if adopt general insulating bar to connect, two people are difficult to operation, and increase risk of by mistake touching charging equipment out of control.Therefore the insulating bar that, high-altitude insulation junction pole is telescopic structure can avoid above-mentioned problem to occur.
In sum, 500kV capacitance type potential transformer high voltage test jointing clamp device of the present utility model adopts arc-shaped elastic metal pliers, solve the problem that original overhead jointing clamp width of jaw deficiency cannot wiring, staff can be operated on the ground, the risk of having avoided work high above the ground to fall, has improved efficiency and safeguard work personnel's safety.Contact is good, practical: new arc-shaped elastic metal pliers can with the metal flange good contact of instrument transformer, utilize its tension force, meet different diameter requirements, reach good test effect; Weight is little, uses light; Reasonable in design, excellent in quality, durable in use, binding clip shortage in weight 1kg.Because arc-shaped elastic metal pliers need to contact well with the metal flange of instrument transformer, therefore arc-shaped elastic metal pliers is adopted to circumferential type structure, can be applicable to the slightly differentiated capacitance type potential transformer of different manufacturers and size, and increase the dynamics that contacts of jointing clamp and capacitance type potential transformer.This arc-shaped elastic metal pliers also has good mechanical strength, carries out suitable adjustment, can dock with metal flange.With after the docking of metal flange, by its elastic shrinkage, play fixing contact action.
