Problems solved by technology
[0002] With the rapid development of the economy, the demand for substations is also increasing; substations need to be repaired during power outages during daily use, and grounding rods are required during the repair process; due to the relatively large operating space of the contacts in the switchgear Narrow (maximum hole diameter does not exceed 10mm), the holding position of the grounding rod is a copper rod contact with a diameter of 30mm, and the direction is directly facing; the conventional operating position of the grounding rod is generally up and down or vertical operation, which cannot meet this kind of grounding contact. Grounding method with fixed head position and narrow operating space

Embodiment Construction
[0020] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of the present invention.
[0021] Combine figure 1 —5 shows a ground rod for a central switch cabinet, wherein the ground rod for the central switch is composed of a wire end clamp, a ground operating rod, a short-circuit ground wire and a ground terminal. The wire end clamp and the short circuit The ends of the grounding wires are connected together; the short-circuit grounding wires include two-phase and split-phase methods. They are compo...

The invention relates to the field of high-voltage power transmission and distribution equipment, and specifically relates to a centrally installed switch cabinet ground rod. The centrally installed switch cabinet ground rod consists of four parts, including a wire end clamp, a ground operation rod, a short-circuit ground wire and a ground terminal; the wire end clamp is connected with the upper end of the short-circuit ground wire; the short-circuit ground wire comprises a combined-phase mode and a split-phase mode, and consists of a wiring terminal and a tin-plated soft copper wire with a sheath, wherein the lower end is connected with the ground terminal and then the wire end clamp is operated by the ground operation rod to connect a conductor which needs to be grounded; and the ground terminal comprises a common ground clamp and a special ground clamp for five prevention closedown. The centrally installed switch cabinet ground rod is simple and convenient to operate in the specific implementation process and has a horizontal 180-degree operation mode; meanwhile, the wire end clamp and the centrally installed switch cabinet ground rod can be detached; and the centrally installed switch cabinet ground rod is 20-35mm in clamping diameter and high in clamping force, does not fall off easily, and has no influence to a suspension power failure overhaul indicator.
Description
Technical field [0001] The invention relates to the field of medium and high voltage power transmission and distribution equipment, in particular to a ground rod of a middle switch cabinet. Background technique [0002] With the rapid development of the economy, the demand for substations is also increasing; substations need to be repaired during power outages during daily use, and grounding rods are required during the maintenance process; due to the comparison of the operation space of the contact positions in the switchgear Narrow and small (the maximum hole diameter does not exceed 10mm), the holding position of the ground rod is a copper rod type contact with a diameter of 30mm, and the direction is directly facing; the conventional ground rod operating position is generally up and down or vertical operation, which cannot meet this type of ground contact The head position is fixed and the operation space is narrow. Summary of the invention [0003] The technical problem to b...
