At the level of production operation and system safety, the hazards of incorrect use of grounding wire clamp cannot be ignored, because the effects of these levels are not limited to a single equipment or local links, but are more likely to cause a chain reaction, causing a serious impact on production order and system stability.
From the perspective of production operation, incorrect use of grounding wire clamp can cause production interruption and economic losses. In the fields of industrial manufacturing, energy supply, etc., the stable operation of equipment depends on reliable grounding protection. Improper connection of grounding wire clamp may become a breakpoint in the production chain. For example, if the reactor of a chemical plant leaks electricity due to the loosening of the grounding wire clamp, the leakage protector will force the trip to stop, which will not only interrupt the continuous production process, but may also cause material scrap, reaction interruption and other problems. The loss of a single shutdown can reach tens of thousands of yuan. In the power industry, if the grounding wire clamp is installed in the wrong location during the maintenance of a substation, it may lead to an accidental power transmission accident, causing equipment to burn down, and the repair cycle lasts for several days or even weeks. During this period, the regional power supply is affected, and the chain reactions such as business shutdowns and inconvenience to residents will further amplify economic losses. In addition, ground fault troubleshooting often requires professionals to use special instruments to detect, which is time-consuming and laborious, and every time the stagnation time of the production line increases by one hour, the company's order default risk and labor cost pressure will also rise simultaneously. More seriously, poor grounding may cause electric sparks, and even trigger fires and explosions in flammable and explosive environments. Catastrophic consequences such as plant damage and equipment scrap may occur, and the economic losses caused may exceed the company's ability to bear.
Incorrect use of grounding wire clamp can also destroy the stability and safety protection system of the power system. The grounding wire clamp is an important part of the protection of the power system. The wrong grounding method can cause loopholes in the entire protection system. In a three-phase power system with a neutral point grounded, if the grounding wire clamp has poor contact, it will cause the neutral point potential to shift, causing a three-phase voltage imbalance. If it is light, it will cause the motor to overheat and burn down, and if it is heavy, it will cause transformers, capacitors and other equipment to breakdown due to overvoltage. In a lightning protection grounding system, if the cross-sectional area of the grounding wire clamp is insufficient or the joint is loose, the grounding resistance will exceed the safety standard. When lightning hits the line, the current cannot quickly pass through the grounding wire clamp and enter the earth. The reverse impact along the line will penetrate the lightning arrester, switchgear and other equipment, causing regional power outages. At the same time, incorrect grounding will interfere with the signal transmission of the power monitoring system, resulting in malfunction or failure of leakage monitoring, overcurrent protection and other devices. When a real failure occurs, the protection system cannot respond in time, causing local failures to quickly spread into systemic accidents.
In short, the incorrect use of grounding wire clamp has a great impact on the continuity of production and operation and the safety of the power system. Whether it is enterprise production or public power supply, it is necessary to standardize the use of grounding wire clamp to avoid serious consequences such as production stagnation and system paralysis due to grounding problems.
