Description

Technical Field

[0001] The utility model relates to the technical field of circuit maintenance, and particularly relates to a novel short - circuit grounding wire rod. Background Art

[0002] At the present stage, before the maintenance of high - voltage equipment, the electrical equipment must be prepared before maintenance according to technical measures to prevent personal and equipment safety. The technical measures include power outage, voltage testing, hanging grounding wires, and installing barriers. Among them, hanging grounding wires is particularly important. At present, in the power industry, the grounding wire is composed of a multi - strand soft copper wire of 25 square millimeters and an insulating rod, and the end of the insulating rod has a connector for connecting to electrical equipment. After being connected to the electrical equipment, it cannot intuitively reflect whether the grounding wire is firmly connected, and there is no obvious prompt for the grounding point during night outdoor work. In this way, it is very easy to fail to remove the grounding wire in time after night maintenance. If power is supplied without removing the grounding wire, it will violate the "hanging grounding wire and closing the circuit breaker" in the "five - prevention" of the power regulations, causing a three - phase short - circuit of the system, bringing huge potential safety hazards and property losses to personnel and electrical equipment.

[0003] Therefore, there is an urgent need for a novel short - circuit grounding wire rod to solve the problems that after the existing grounding wire is connected to the electrical equipment, it cannot intuitively reflect whether the grounding wire is firmly connected, there is no obvious prompt for the grounding point during night outdoor work, it is easy to fail to remove the grounding wire in time after night maintenance, and potential safety hazards and property losses are brought. Summary of the Utility Model

[0004] The utility model provides a novel short - circuit grounding wire rod to solve the problems that after the existing grounding wire is connected to the electrical equipment, it cannot intuitively reflect whether the grounding wire is firmly connected, there is no obvious prompt for the grounding point during night outdoor work, it is easy to fail to remove the grounding wire in time after night maintenance, and potential safety hazards and property losses are brought.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A novel short - circuit grounding wire rod, comprising:

[0007] An insulating rod, one end of the insulating rod is provided with a handle, and a control cable is arranged in the insulating rod;

[0008] A connecting joint, the connecting joint is connected to one end of the insulating rod, the connecting joint has an arc - shaped clamping piece, the arc - shaped clamping piece includes a first arc - shaped card and a second arc - shaped card, the first arc - shaped card and the second arc - shaped card form an arc - shaped groove for clamping, and the first arc - shaped card and the second arc - shaped card can approach or move away from each other;

[0009] Lighting assembly, the lighting assembly includes a lamp, a power source and a push-pull switch, the lamp, the power source and the push-pull switch are connected in series through a control cable, and the lamp is also connected to the control cable in the insulating rod.

[0010] Furthermore, a first spring and a second spring are arranged inside the connection joint, one end of the first spring is connected to the inner wall of the first arc-shaped card, and one end of the second spring is connected to the inner wall of the second arc-shaped card.

[0011] Furthermore, two screws for fixing the grounding wire are arranged on the insulating rod.

[0012] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are:

[0013] During actual use, when the grounding rod is fully hung, the lamp of the connection joint will keep flashing, which also indicates that the connection joint of the grounding rod is firmly connected to the electrical equipment. There is a push-pull switch on the connection joint. As the connection joint and the conductor of the electrical equipment are manually tightened, the first arc-shaped card and the second arc-shaped card in the connection joint open, and the push-pull switch installed on the arc-shaped groove changes from normally open to normally closed, turning on the control circuit and the flashing lamp starts to work. At this time, it shows that the connection joint of the grounding rod is reliably connected to the electrical equipment and emits a flashing light signal. When the maintenance is over, first remove the grounding rod and then remove the grounding wire. At this time, the push-pull switch changes from normally closed to normally open, and the control loop of the circuit is disconnected, and the flashing signal disappears. The benefits that the present utility model can bring are: 1. This grounding rod can intuitively reflect the grounding situation of the equipment. If the grounding rod falls or is loosely connected, it can be immediately discovered, ensuring personal and property safety. 2. When working at night on overhead lines or in situations with insufficient lighting, it can timely remind the maintenance personnel of the specific position of the grounding wire and the grounding situation of the equipment to be maintained, preventing the grounding wire from being forgotten to be removed after the maintenance is over.
