Problems solved by technology

[0003] The length of each of the existing two test wires is 5m, and the total weight reaches 5Kg, and the test personnel need an insulation ladder to climb up the outdoor high-voltage switch, especially the 35kV, 110kV and above high-voltage switches, which are large in size and high in structure. The test lead is very inconvenient, or the transfer rope is used to lift it up. Due to the heavy weight, the test personnel consume a lot of physical strength

Embodiment Construction

[0028] Such as figure 1 As shown, a special wiring rod for a large current generator includes a double-tongue hook 11, and two screws 12 are arranged on the double-tongue hook, and the screws are used to connect a 5-meter-long test lead. The lower side of the double-tongue hook A universal joint 13 is connected, and the universal joint is connected with an insulating rod 14. The insulating rod can be provided with multiple sections, and a tightening mechanism 3 is provided between adjacent insulating rods or between the universal joint and the insulating rod. An insulating rubber handle 15 is provided at the lower end of the insulating rod.

[0029] In order to optimize the design of the scheme, the insulating rod can adopt a telescopic rod design. For example, the first insulating rod can be slidably fitted in the second insulating rod and positioned at one place on the second insulating rod, and the second insulating rod can be positioned on the third insulating rod. The in...

Abstract

The invention provides a special wiring rod for a large current generator, and relates to the field of testing instrument wiring. The special wiring rod comprises a double tongue hook, wherein the double tongue hook is provided with two screws for connecting test wires, and the lower side of the double tongue hook is connected with a universal joint, the universal joint is connected with a plurality of insulating rods which are connected in sequence, tightening mechanisms are arranged between the adjacent insulating rods, and an insulating rubber handle is arranged at the lower end of the insulating rods. The special wiring rod utilizes the design of the tightening mechanisms and a flexible fine adjustment mechanism, so that the special wiring rod is convenient to assemble and disassemble,and the safety hazard in manually climbing of the outdoor high voltage switch is avoided. Thanks to the design of the flexible fine adjustment mechanism, the double tongue hook at the top has multiple degrees of freedom, and the wiring on both sides of inlet and outlet leads of the switch can be easily and conveniently realized under the switch.

Description

technical field [0001] The invention relates to the field of test instrument wiring, in particular to a special wiring rod for a large current generator. Background technique [0002] The large current generator is used for power system inspection of current transformers, protection devices and secondary circuit current tests. When testing the current transformer of the outdoor high-voltage switch, the tester needs to carry two test wires, climb up the outdoor high-voltage switch and use the test clamp to connect the two sides of the switch inlet and outlet wires. The test lead is composed of two parts, the lead wire and the terminal. The lead wire core is wound with multiple strands of bare copper wire, with a diameter of 50mm. 2 , length 5m, weight 5Kg, plastic insulation transparent protective cover. One end of the wire is a high-current test clamp, which is connected to the wires on both sides of the switch inlet and outlet, and the other end is a copper lug connected ...
