Usage and precautions:

Usage and precautions:

Garanta a integridade do fio de aterramento e guarde -o em um local especial com boa ventilação e ambiente seco.

O uso deste fio de aterramento em equipamentos elétricos deve cumprir as disposições relevantes dos procedimentos de trabalho de segurança elétrica.

Antes de usar o fio de segurança, é necessário verificar a eletricidade e a descarga, confirme se o equipamento elétrico foi cortado e pendure o fio de aterramento antes da operação.

ANTES DE USAR DE FIO DE SEGURANCA, É NECESSÁRIO Veríntar a eletricidade e um desclarga, confirmando o equipamento elétrico para cortado e pêndão de fio de aterramento antes da operação.

Before using the security wire, routine inspection shall be carried out. It is prohibited to use the security wire when cracks, defects, poor contact of connecting parts, looseness, damage of insulation sheath and other defects are found.

Usage method:

The correct use of the grounding wire of the central cabinet. Hang the grounding wire. After the line is verified to be free of voltage, the grounding wire shall be hung at both ends of the working section immediately. All branch lines that may be powered to the blackout line shall also be grounded. If the induced voltage is reflected on the outage line, the grounding wire shall be hung. At the same time, pay attention to prevent inductive electric shock when removing the grounding wire.
When the multi-layer power lines erected on the same tower are hung with grounding wires, the low voltage shall be hung first, then the high voltage, and the lower layer shall be hung first, then the upper layer.
When hanging the grounding wire, the grounding terminal shall be connected first, and then the conductor terminal. The grounding wire shall be connected reliably and shall not be twisted. The procedure for removing the grounding wire is the opposite. When installing and disassembling the grounding wire, the staff shall use insulating rods or wear insulating gloves, and the human body shall not touch the grounding wire. If the tower has no grounding downlead, temporary grounding rod can be used, and the depth of the grounding rod under the ground shall not be less than 0.6m.
The grounding wire of the central cabinet shall be a complete set of grounding wires composed of grounding and short circuit conductors. The complete set of grounding wires shall be composed of multiple strands of soft copper wires, and its sectional area shall not be less than 25mm2. If the tower is used for grounding, each phase is allowed to be grounded individually, but the connection part between the tower and the grounding wire should be cleaned of paint and have a good contact.

Matters needing attention:

Before the formal work, the whole set of grounding wires must be checked to see whether the flexible copper wire is broken, whether the sheath is damaged, whether a few screws are fastened, and whether the spiral of the hook is normal. If it does not meet the requirements, it shall be replaced or repaired in time before use.
Before the grounding wire is hung, the line must ensure that there is no voltage and current before the grounding wire is hung. During the electrical inspection, the qualified electroscope with the same voltage level must be used. The purpose of electricity inspection is to confirm whether the power has been cut off at the site, which can eliminate the human error of power failure and non power failure, and prevent the electrified grounding wire.
The grounding wire shall not be placed randomly and hung on the stay wire or metal tube in the running line. Its resistance is unstable, often too large, and does not meet the technical requirements. It may also make the metal tube live, causing harm to others.
The grounding wire with corresponding specifications shall be selected according to different voltage levels, and the wire diameter of the grounding wire shall match the voltage level of the electrical equipment.
It is not allowed to clamp the grounding wire onto the painted metal frame or metal plate, because the painted surface is an insulator, and the withstand voltage of the paint thickness reaches 10KV/MM, which can make the grounding circuit impassable and lose its protection.
It is forbidden to use other metal wires instead of grounding wires. The contact of other metal wires is not firm, and the fault current will quickly melt the metal wires, disconnect the grounding circuit, and endanger the lives of workers.
On site work, it is not allowed to hang the base county less or change the location of the grounding wire without authorization. The number of grounding wires and the location of the grounding wire are carefully considered by the work permit. If the grounding wire is hung less or the location is changed, the protection effect of the site will be reduced and the staff will be in a dangerous working state.
Sign boards or temporary barriers shall be hung on the construction site.
The grounding wire is double-edged and has a safety effect. Improper use will also cause damage. Therefore, the grounding wire should be removed in time after the work is completed. The switch with grounding wire will damage the electrical equipment and the stability of the power grid, which will lead to serious electrical accidents.

Before the electricity inspection, the grounding wire shall be prepared and its grounding terminal shall be connected to the terminal of the grounding grid (pole). When it is verified that the equipment or line has no voltage and is discharged, the maintenance equipment or line shall be grounded and three-phase short circuited immediately.

For all links that may be powered to the power failure equipment and lines, including all branches of the line or power failure equipment that may generate induced voltage, the grounding wire shall be installed at a visible position at the operation site. The distance between the grounding wire and the live part shall comply with the safety distance regulations.

When working on the indoor power transformation and distribution device, the grounding wire should be installed at the specified position of the bus or conductive part. These positions should not be painted with phase paint, and there should be special grounding signs. The outgoing terminal of the grounding grid shall be set at the appropriate position of the power transformation and distribution device, so that the grounding terminal of the grounding wire can be well connected here. The grounding resistance value of the terminal must be qualified

When installing the grounding wire, the grounding terminal must be connected first, and the live end of Houjie that has been cut off. When removing the grounding wire, the live end that has been cut off must be removed first, and then the grounding terminal can be connected. Grounding rods or insulating gloves shall be used for assembling and disassembling grounding wires.

The grounding wire operation must be carried out by two people. If the substation is on duty, only the grounding disconnector can be used for grounding.
