The utility model discloses a special rod for the test of a 10kV switch cabinet lightning arrester, which includes an insulating rod, an axial hole and a radial hole are arranged on the upper part of the insulating rod, and the axial hole and the radial hole are connected to each other. The axial hole and the radial hole run through a test wire, the upper end of the test wire is connected to the metal hook, the lower end of the metal hook is movably connected to the upper end of the insulating rod, and the lower end of the test wire is connected to the tester. The utility model can make the test wiring directly reach the tested equipment, and further realize the test without dismantling the tested equipment, prevent operators from accidentally touching live equipment, and eliminate potential safety hazards.
Description
One. technical field: the utility model relates to a kind of power equipment high-potting field, particularly relates to a kind of 10kV switch cabinet lightning arrester test special pole.
Two. background technology: because 10kV switch cubicle volume is less, the installation site of lightning arrester is generally all inboard near cabinet, and dismounting is very difficult when making the lightning arrester test.Utilities Electric Co.'s testing crew is when carrying out the test of 10kV switch cabinet lightning arrester; General being crept in the switch cubicle by the maintainer earlier removed lightning arrester and take out outside the cabinet; By testing crew lightning arrester is carried out pilot projects such as Leakage Current then, by the maintainer lightning arrester is restored to the original state again after the stand the test.In addition, the maintainer will creep into cabinet and carry out operation in disassembly process; And the 10kV bus also exposes at cabinet inner in the part switch cubicle; Because the space is narrow and small in the cabinet, the potential safety hazard that the maintainer exists mistake to bump charging equipment when operation threatens the person, equipment and power grid security.The structure of existing lightning arrester check bar is referring to Fig. 1, among the figure, and 1-insulating bar, 2-insulated hook.
Three. the utility model content:
The utility model technical matters to be solved is: overcome the deficiency of prior art, a kind of reasonable in design, easy to use, 10kV switch cabinet lightning arrester test special pole of reducing lightning arrester dismounting formality and increasing work efficiency is provided.
The technical scheme of the utility model is: a kind of 10kV switch cabinet lightning arrester test special pole, contain insulating bar, and said insulating bar top is provided with an axial hole and radial hole; And; Said axial hole and radial hole connect each other, are penetrated with test connection in said axial hole and the radial hole, and said test connection upper end is connected with metal hook; Said metal hook lower end and said insulating bar movable connection of upper end, said test connection lower end is connected with test instrument.
Said test connection is an insulated conductor, and said metal hook is a decussate texture, and is provided with barb on the top of decussate texture.Said barb is an arc.
The beneficial effect of the utility model is:
1, the utility model can make test connection directly reach tested device, and then realizes that not tearing equipment under test open can make an experiment, and stops operating personnel's mistake and bumps charging equipment, has eliminated potential safety hazard.
2, be movable connection between the utility model metal hook and the insulating bar, be convenient to dismounting, easy to use, and high efficiency.
3, the utility model reasonable in design, easy to use, reduce lightning arrester dismounting formality and increase work efficiency, it is applied widely, is easy to promotion and implementation, has good economic benefit.
Four. description of drawings:
Fig. 1 is the structural representation of lightning arrester check bar in the prior art;
Fig. 2 is the structural representation of the utility model 10kV switch cabinet lightning arrester test special pole.
Five. embodiment:
Embodiment: referring to Fig. 2, among the figure, 1-insulating bar, 3-through wires hole, 4-test connection, 5-metal hook.
10kV switch cabinet lightning arrester test special pole contains insulating bar 1, and insulating bar 1 top is provided with an axial hole and radial hole 3 (axially not drawing in the hole pattern), and; Axial hole and radial hole 3 connect each other; Be penetrated with test connection 4 in axial hole and the radial hole 3, test connection 4 upper ends are connected with metal hook 5, metal hook 5 lower ends and movable connection of insulating bar 1 upper end; Can dismounting, test connection 4 lower ends are connected (not drawing among the figure) with test instrument.
During use, hold insulating bar 1 metal hook 5 is connected on the 10kV switch cabinet lightning arresters, and with the other end effective grounding of lightning arrester, opening test instrument can make an experiment.
The utility model can make test connection directly reach tested device, and then realizes that not tearing equipment under test open can make an experiment, and stops operating personnel's mistake and bumps charging equipment, has eliminated potential safety hazard.
