Ground wire Contact: Dual Manager Tel: 15373866203 Qq: 2103662569 1. grounding purposes: When electrical equipment and power lines maintenance outage, in order to ensure the safety of operating personnel, to take measures to ensure the safety of the technology, that all or part of a power outage Electrical power equipment to be installed on each side of the ground wire may caller that manually grounded grounding wire connected to the electrical equipment, its role is to make the work place is always in the protection of "ground" of being, but also can prevent residual charge and induced charge bodily harm; in the event of erroneous delivery point, make the protection action, quickly cut off the power to prevent the risk of accidents and arc voltage generated calls. If the circuit breaker maintenance, in addition to isolating switch off the circuit breaker on both sides, but also on both sides of the ground breaker mounted in groups; it should be installed in the ground wire on the line when the same job ,, maintenance outage will likely calls The sides of the three-phase short circuit to ground, to protect workers from electrical shock. 2. constitute shorting the ground wire is especially delicate multi-strand copper wire soft synthetic wave, external layer of transparent pvc insulated casing, then the pressure on the nose grounding line: There are two kinds of grounding clamp and ground pins to , ground to pin specific length customized on request. Grounding clamps and ground operations rods and hooks are made of aluminum bronze, but the relatively high cost of copper, aluminum and now multi-use. Classification 3. ground wire: ground wire into portable short-circuit ground wire and grounding wire personal security. Portable short-circuit ground wire is divided into modular and phase two. 1) combined ground line due to the different voltage levels, the number of clips, the length of the grounding wire is also different. By wire end clamp, operating rod, short line, ground wire and ground clamp or grounding electrode composed of a "ground wire." When using a priori power outage after the confirmation has been secured to the ground clamp grounding the wire ends were hanging on the wire clamp clamping. Demolition should first remove the wire end clamp, after the removal of ground clamp 2) phase grounding wire each of three groups. Each group lead by the end of the clip, short routes and ground clamp piece. When using packet operation should a priori power outage has been confirmed, first ground clamp fastened to poles on the ground (or on the tower), and then press the power line voltage level, the selected operating rod, clamp the wire ends to hang On the wire clamp. After work, you should first remove the wire end clamp, after the demolition ground clamp. The role and type of personal security personal security grounding wire grounding line: personal security personal grounding device grounding line (commonly known as "small earth") is used to prevent hazards induced voltage can be divided into high-pressure and low personal security grounding wire with a personal Security grounding wire maintenance before using portable short-circuit ground wire [4], should confirm a priori power outage, after confirming that no voltage on the device. First grounding clamp connected to the ground network or flat iron, then stick with the ground operation will lead end line classes were tightened on the device leads. When removing the short-circuit ground wire, just above the opposite order. Installation of a short-circuit ground wire from it and live equipment, taking into account the impact of the grounding wire pendulum, its safe distance should not be less than the value of the new regulations, "electrical safety work order." The wound is prohibited by methods not shorted to ground clamp. If ground suspension points, or application-specific copper grounding clamp for ground connection; if no fixed ground available; you can use a temporary ground, grounding buried depth should not be less than 0.6m. Portable short-circuit ground wire should be properly kept. Before each use, should be carefully examined whether intact, no soft to bare copper wire, nuts are not loose, shall not be used. Portable short-circuit ground wire test cycle once every five years, with factory inspection test items. After passing the test of portable short-circuit ground wire after being subjected to short-circuit, short-circuit current withstand should be based on the size and appearance inspection judgments generally should be scrapped Shijiazhuang Golden Power Equipment Co., Ltd.
