JDX-35KV double spring high voltage short-circuit grounding wire

JDX-35KV double spring high voltage short circuit grounding note:
(1) When connecting the grounding wire: Connect the grounding clamp first and then connect the clamp; when removing the grounding wire, it is necessary to disconnect the clamp first according to the procedure, and then remove the grounding clamp.
(2) Device: Connect the grounding wire to the monocular copper nose with the eyes fixed on the grounding rods on the grounding copper wire phase split. (The clamps are fixed and movable) It is fixed on the ground clamp or the ground pin to form an intact grounding wire.
(3) Verify that the voltage level of the grounding rod is the same as the voltage level of the operating equipment.
(4) Make sure that the equipment or circuit is used after the power is turned off.
(5) Operation process The operator should wear related protective equipment, such as insulating boots, insulating gloves and safety helmets, and use them under special supervision.
JDX-35KV double spring high voltage short-circuit ground wire classification:
1. When the high-voltage line or equipment is in overhaul, in order to avoid sudden power transmission, the three-phase overhead line or busbar on the power supply side should be temporarily grounded with a grounding wire.
2. To avoid damage to the human body due to the voltage induced by adjacent high-voltage lines or devices on the power-off lines or equipment, or to cause damage to the human body due to the induced voltage of the power-off maintenance equipment or the line. The ground of the power-off maintenance circuit or the relevant parts of the equipment should be used. Temporarily grounded.
3. When working on the device after a power outage, use the grounding wire to discharge the remaining charge on the device with a temporary grounding wire, that is, release the remaining charge, commonly known as "discharge."
(1) The high-voltage grounding wire can be divided into the indoor bus-type ground wire (JDX-NL) and the outdoor wire-type ground wire (JDX-WS) according to the operating environment.
(2) The high-voltage grounding line can be divided into 10KV grounding line, 35KV high-voltage grounding line, 110KV grounding line, 220KV high-voltage grounding line, and 500KV high-voltage grounding line according to the voltage level.
(3) The length of the insulated operating rod required by the grounding wire is as follows:
380v ground wire, 500v ground wire, 6kv ground wire, operating rod length 50CM
10KV ground wire operation rod length length 1 meter
35KV grounding wire insulation operating rod length 1.5 meters
110KV grounding wire insulation operating rod length 2 meters
220KV grounding wire insulation operating rod length 2.5 meters
500KV grounding wire insulation operating rod length 8 meters
JDX-35KV double spring high voltage short-circuit ground wire skill requirements:
1. The construction grounding wire consists of a grounding terminal, a grounding conductor, and a splint with a spring. The ground wire sheath has an insulating layer. When colliding with the wire, the clamping spring in the clamping plate actively clamps the wire.
2. The cross section of the construction grounding wire should be selected according to use.
3. Firstly fasten one end of the construction grounding wire to the grounding body with a bolt, turn the clamping plate of the clamping body open, and support the tension spring plate. The operator's portable grounding wire is used to align the clamping body with the wire or overhead grounding wire to be grounded. After colliding, the clip body clamps the wire or the ground wire.
4. When removing, remove the splint and loosen the grounding bolt.
5. In places where the induced voltage is high, construction workers should wear antistatic clothing.
6. It is necessary to hang a grounding warning sign at the grounding point.

Stamping (also known as pressing) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining.This could be a single stage operation where every stroke of the press produces the desired form on the sheet metal part, or could occur through a series of stages. The process is usually carried out on sheet metal, but can also be used on other materials, such as polystyrene. Progressive dies are commonly feed from a coil of steel, coil reel for unwinding of coil to a straightener to level the coil and then into a feeder which advances the material into the press and die at a predetermined feed length. 


Stamping is usually done on cold metal sheet. See Forging for hot metal forming operations.
