Description

A grounding device for substation installation and debugging

technical field

The invention belongs to the technical field of equipment for substation installation and debugging, and in particular relates to a grounding device for substation installation and debugging.

Background technique

A substation is a place in a power system that transforms voltage and current, receives electric energy and distributes electric energy. The substation in the power plant is a step-up substation, whose function is to boost the electric energy generated by the generator and feed it to the high-voltage grid. The grounding device generally used in the installation and commissioning of substations is to connect the grounding wire to the ground through the insulating rod. The grounding wire is an important tool in the power system to ensure the safety of the staff when the voltage appears unexpectedly on the equipment and lines that have been powered off. Its function is When the high-voltage equipment is undergoing power outage maintenance or other work, it can prevent the equipment from suddenly receiving power and the induced voltage generated by the adjacent high-voltage live equipment from harming the human body, and at the same time discharge the remaining charge of the power-off equipment. Installing and removing temporary ground wires is an important maintenance operation in power systems. At present, portable short-circuit grounding wires are usually used in the maintenance work of substation equipment in substations, and the short-circuit grounding wires are mainly hung on the maintenance equipment or conductors by using insulating operating rods.

However, at the substation installation, commissioning or maintenance site, the grounding point of some equipment is too high, and it is very difficult for the staff to manually hang the grounding wire; therefore, this manual hanging method is suitable for 10kV with a small insulation distance and a short distance between the equipment and the ground. It is more suitable for equipment up to 110kV, but for open ultra-high voltage equipment with a voltage level of 500kV and above 1000kV UHV equipment, due to the large insulation distance of the equipment, the installation height of the equipment is also relatively high, and the method of manually hanging the ground wire on the insulating rod is used. Often difficult to achieve. The total length of the insulating part and the handshake part of the conventional grounding rod applied to 500kV equipment and transmission lines is only 5500mm. However, the distance between the static contact of some grounding switches and the ground has reached 9000mm. Therefore, in the actual work site, even if the longest grounding operation rod is used, the staff must hang the grounding wire manually at a height of about 3 to 4 meters. Since the 500kV grounding wire has a large weight and the length of the grounding rod is too long, in this case, the staff is prone to the risk of falling from a high altitude and the risk of inductive electric shock when operating manually.
