Description

UHV grounding wire device

technical field

The utility model relates to a grounding wire device, in particular to a UHV grounding wire device.

Background technique

At present, the installation of temporary grounding wires in the power system is to first connect the grounding end of the grounding wires, and then hang the clamps on the power equipment, because the grounding wires must have a cross-sectional area of 25mm2 ^or more and the short-circuit current is more than qualified Strand soft copper insulated wires are often too long and heavy, and the clamping operation is complicated and dangerous, and it is easy to damage the electrical equipment after clamping.

Contents of the invention

The technical problem to be solved by the utility model is to provide an ultra-high voltage grounding wire device, which can avoid damage to electric equipment due to excessive length and weight of the grounding wire, reduce the probability of accidents, and is safe, reliable, and easy to operate. .

In order to solve the above technical problems, the technical solution of the utility model is: a UHV grounding wire device, including a grounding wire, one end of the grounding wire is provided with a grounding copper bar, the other end of the grounding wire is connected to a connecting pipe, and the connecting pipe is provided with a branch Press the hook, and the spring clamp is connected to the connecting pipe through a single-phase ground wire.

A portable hook is installed on the single-phase ground wire.

An insulating rod is provided on the spring-loaded clamp.

The grounding copper bar is matched with the grounding pile device, and a five-proof mechanical lock is installed on the grounding pile device.

The UHV grounding wire device provided by the utility model, because the connecting pipe is provided with a voltage dividing hook, shares the weight of the grounding wire, reduces the pressure on the power equipment, and avoids the impact on the power equipment due to the excessive length and weight of the grounding wire. In the event of damage, the probability of accidents is reduced; for the UHV grounding wire device that adopts the three-phase-in-one grounding method, a portable hook can be installed on the longer single-phase connection line, and the segmented voltage balance is strengthened. Effect; the insulating rod on the spring clamp acts as an extension arm, making it simple, convenient, safe and reliable to hang the clamp. The clamping effect of the spring clamp is good, and it will not cause damage to the surface of the electrical equipment; the grounding stake The design of five anti-mechanical locks on the device prevents the grounding pile device from being accidentally removed when the grounding wire is connected, and prevents the wrong connection of the grounding wire or the wrong interval when the grounding wire is not connected, which improves the anti-mistake locking function , Effectively guarantee the safety of maintenance personnel.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the structural representation of the utility model.

Detailed ways

As shown in Figure 1, the utility model includes a grounding wire 3, one end of the grounding wire 3 is provided with a grounding copper bar 7, the other end of the grounding wire 3 is connected with a connecting pipe 10, and the connecting pipe 10 is provided with a pressure-dividing hook 8, a spring-type wire The clip 5 is connected to the connecting pipe 10 through a single-phase ground wire 9 .

A portable hook 4 is installed on the single-phase ground wire 9 .

An insulating rod 6 is arranged on the spring clamp 5 .

The ground copper bar 7 cooperates with the ground pile device 2, and the five-proof mechanical lock 1 is installed on the ground pile device 2.

When in use, first connect the grounding copper bar 7 to the grounding stake device 2, then hang the voltage dividing hook 8 on the fixed pillar frame, and then hold the insulating rod 6 to open the spring clamp 5 so that it clamps the suspension point of the power equipment Just wire.

If the length of the single-phase grounding wire 9 is too long, the portable hook 4 can be hung on the fixed pillar frame for segmental partial pressure.
