Description

Technical Field

[0001] The utility model relates to the technical field of electrical test insulating grounding rods, in particular to an electrical testable grounding rod. Background Art

[0002] The insulated grounding rod for power testing is a unified name for a group of insulating tools specially used in power systems. It can be used for live working, live inspection and live maintenance work. The insulated grounding rod for power testing is an insulating tool used to operate live equipment for a short time, such as connecting or disconnecting high-voltage disconnectors, drop fuses, etc. There are many types of insulated grounding rods for power testing. Insulated grounding rods are divided into fixed-length and telescopic types, and the applicable scenarios are also different. In order to improve safety during operation, some insulated grounding rods for power testing will install a connecting wire at the position of the clamp and connect it to the ground wire, directing the current transmitted by the clamp contacting the wire to the ground.

[0003] The length of the telescopic test insulation grounding rod is adjustable, so the required connecting wire is longer. The traditional test insulation grounding rod cannot store the connecting wire. When used in a location where the wires are relatively messy, the connecting wire is very easy to be entangled with the wires. On the one hand, it is not convenient for the test operation. On the other hand, it is not easy to remove the test insulation grounding rod because the wires and the connecting wires are entangled. For this reason, a testable grounding rod is proposed, which stores the connecting wires through a wire pull rod to solve the above problems. Utility Model Content

[0009] Preferably, the outer ends of the support rod and the slide rod are fixedly connected with a clamping plate, the connecting wire is clamped inside the clamping plate, the outer end of the support rod is fixedly connected with a controller, and the controller is electrically connected to the alarm.

[0010] Preferably, the bottom of the support rod is rotatably connected to a rotating shaft, the bottom of the sliding rod is fixedly connected to a connecting nut, the top of the rotating shaft is fixedly connected to a screw rod, and the screw rod and the connecting nut are threadedly connected.
