Description
Technical field
The invention belongs to electric power overhaul field of tool, is the termination that a kind of safety coefficient is higher.
Background technology
At present; there is task weight in the teams and groups of electric company, teams and groups personnel are few; the professional installation of the administrative all transforming plant protectings of the company that is responsible for, telemechanical, communication, direct current four, debugging, maintenance, maintenance work, almost contain all secondaries of transformer station, three times, the various equipment such as communication.Therefore, utilize technological means to increase work efficiency, use manpower and material resources sparingly extremely urgent.There is potential safety hazard in altitude test wiring: as maintenance teams and groups, robotization class has a large amount of prerun, annual test, service work every year.When testing the electric equipment that can not directly contact or overhaul, teams and groups personnel are needed to climb to a higher point wiring.Especially for the primary equipment of 110kV transformer station, distance floor level is high, during test connection, double ladder must be taked to ascend a height wiring.This working method both took manpower, there is potential safety hazard again.Must take effective measures, reduce ascend operation, just can increase work efficiency.
Summary of the invention
The object of the invention is to overcome existing deficiency, provide a kind of spiral jointing clamp that reliably can be connected with equipment, control lever designs and produces simple telescopic high altitude test wire connector; Be applicable to various altitude test wiring.
For achieving the above object, technical scheme provided by the invention is: a kind of telescopic high altitude test wire connector, is characterized in: it comprises overhead jointing clamp, insulating bar, connecting line; Overhead jointing clamp comprises the binding clip being controlled to tighten up jaw by screw rod rotation, and magnetic-type inner sleeve is housed below screw rod, and magnetic-type inner sleeve both sides are provided with bayonet lock; Connecting line adopts multiply annealed copper wire, the upper end of multiply annealed copper wire is welded on copper nose lower end, bar shaped geometrical clamp is pasted with at the back side of copper nose, the lower end intermediate plate of geometrical clamp is wrapped in multiply annealed copper wire external application holding screw and fixes, the upper borehole jack of copper nose and geometrical clamp is on the upper laterodorsal fastening bolt of binding clip, with fastening nuts, be fixedly pasted with the multiply annealed copper wire of bar shaped geometrical clamp at the back side, the downside stator of binding clip; Insulating bar comprises magnetic-type outer sleeve and the scaling operation bar of upper end, and the both sides, upper end of magnetic-type outer sleeve are provided with the draw-in groove corresponding with the bayonet lock of magnetic-type inner sleeve.
The present invention can reduce ascend operation, increases work efficiency, and technological layer overcomes the problem that teams and groups personnel are few, task is heavy, improves teams and groups' work efficiency, the potential safety hazard existed in solution work from science aspect.1, simple to operate: can be fixed on altitude plant cable by rotating binding clip lower end insulating bar, simple to operate.2, safe and reliable: binding clip can not loosen after installing in not operation situation, clamping is reliable.3, overload capacity is strong: it meets brief energization electric current and is greater than 200A.4, use light: lightweight, reasonable in design, durable in use.5, adopt rotation fixing, control lever can shirk, and top installs carrying magnetic screw sleeve additional, simple to operate, and firm grip is reliable, is applicable to outdoor overhead cable wiring.

Embodiment
The present invention it comprise overhead jointing clamp, insulating bar, connecting line; Overhead jointing clamp comprises being rotated by screw rod 9 and controls to tighten up the binding clip 11 of jaw 12, and magnetic-type inner sleeve 8 is housed below screw rod 9, and magnetic-type inner sleeve 8 both sides are provided with bayonet lock 7; Connecting line adopts multiply annealed copper wire 6, the upper end of multiply annealed copper wire 6 is welded on copper nose 2 lower end, bar shaped geometrical clamp 5 is pasted with at the back side of copper nose 2, the lower end intermediate plate of geometrical clamp 5 is wrapped in multiply annealed copper wire 6 external application holding screw 13 and fixes, the upper borehole jack of copper nose 2 and geometrical clamp 5 is on the upper laterodorsal fastening bolt 3 of binding clip, with fastening nuts, be fixedly pasted with the multiply annealed copper wire 6 of bar shaped geometrical clamp 5 at the back side, the downside stator 4 of binding clip; Insulating bar comprises magnetic-type outer sleeve 15 and the scaling operation bar 16 of upper end, and the both sides, upper end of magnetic-type outer sleeve 15 are provided with the draw-in groove 14 corresponding with the bayonet lock 7 of magnetic-type inner sleeve.
Selecting of scaling operation bar mainly considers the following aspects:
1. support the use with overhead jointing clamp, can shirk after binding clip is fixing, and will ensure that binding clip does not come off in upper act and rotary course;
2. consider that 110kV, 35kV device height is different, control lever should have retractility, makes it meet various different work requirements.
3. scaling operation bar 16 should have good insulativity.
The magnetic-type outer sleeve on control lever top is stainless steel sleeve, and jointing clamp fixing in act process in guarantee, rotation process bar drives screw rod 9 to complete the fixing of overhead jointing clamp simultaneously.In order to ensure that bottom overhead jointing clamp, magnetic-type inner sleeve is firmly connected to control lever, bottom magnetic-type inner sleeve and magnetic-type outer sleeve, all magnet being installed, ensureing jointing clamp does not come off in act process,
Scaling operation bar is made by high pressure resistant epoxy glass, and lightweight like this, intensity is high, safe handling in 220kV.Draw-tube 1.2M/ saves, and is connected, ensure its reliability connected between two joints by screw.Connect two joints and can connect 4 meters of height, meet 110kV and test demand.
In order to ensure the reliability of cranking test room, we select 25 ㎜
2multiply annealed copper wire as upper and lower connecting line.With reference to the interface mode of cranking test equipment test line, we utilize copper lug as test harness junction, lower end, make it directly be connected with test apparatus, reduce intermediate connecting ring joint.
We become the test of CT polarity no-load voltage ratio with 110kV ring peak and are as the criterion, and when not using this electric wire connecting junction, every phase CT probably needs 13.5 minutes, and after using electric wire connecting junction, often organizing test period is 7.5 minutes, and averaging time saves 44%.
