How does the electronics factory pull the antistatic grounding wire

1. Ground the power system

The project consists of two three-storey main factory buildings, office buildings and canteens, and despite the tens of thousands of square metres of floor space, the complex is relatively concentrated, so the tn-s system is given priority in the design. Reflective clothing It is the reflective film placed on the surface of clothing, used for night road or road work safety clothing. In the case of no interference at night, the effective distance of reflection and luminous is 500 meters, the safety suit is simple to manufacture, convenient to change the film, low cost, easy to promote, is an ideal night safety protective clothing. Reflective clothing manufacturers for a wide range of people, road traffic police, night action police, sanitation workers, construction workers, the elderly and children, outdoor activities, cyclists, travelers are suitable for wearing reflective safety clothing. The neutral point of the transformer is grounded, and the system protection line is completely separated from the neutral line, which is conducive to power supply, protection and economic rationality. Reflective clothing manufacturers for a wide range of people, road traffic police, night action police, sanitation workers, construction workers, the elderly and children, outdoor activities, cyclists, travelers are suitable for wearing reflective safety clothing. Five-core pe cable is used to supply power to scattered building units equidistant from the main building. Buildings above 50 meters must be repeatedly grounded according to the code requirements.

2. Electrical protection grounding

When TN-S systems are used, the uncharged parts of the electrical equipment are directly electrically connected to the exposed metal ground points of the power network. When the charged phase of the insulating equipment housing is damaged due to collision, a single-phase short-circuit fault is formed relative to the ground by the device housing. A protective device (fuse, low-voltage circuit breaker, etc.) on the line that uses a large short-circuit current quickly cuts the circuit, thereby avoiding the danger of electric shock.

In the factory building of electronic products production enterprises, the teaching equipment on the production line is technology-intensive, and most of them are electrical safety equipment with metal shell. If the grounding of the protection system is not in place or does not meet the standard requirements, it is easy to cause the risk of electric shock to social work researchers in the event of grounding failure. Therefore, the protection of grounding to solve the problem is not let us ignore, whether in the design and development process of students or a construction process, should effectively put the protection of grounding in place. Objects to be grounded for environmental protection include the metal frame or shell of transformers, high-voltage switchgear, power distribution cabinet, and control panel. Metal casings for stationary, portable and mobile electrical appliances; Power line metal resource protection tube or bridge, junction box shell, armored cable skin, etc. The connection wire to protect the ground can be made of flat steel or copper wire, which requires itself to form a reliable electrical path.

Equipotential connection is an indispensable task in the electrical engineering design of various buildings. There are two kinds of equipotential connection: total equipotential connection and local equipotential connection. The so-called total equipotential connection is the connection of PE trunk line, ground dry connection, water main pipe, gas pipe, heating and air conditioning riser at the entrance of the power supply in the building, so that students can analyze the above part of the enterprise in the development of the same potential. Total equipotential connection is an important building or electrical device must be set in the use of cutting off the fault detection circuit to prevent human shock measures. The so-called local equipotential connection method is to reapply the same connection to the structural components of the above research pipeline in a certain local area. As a supplement to the total equipotential connection, it can be used to further improve the information security management level of domestic electricity consumption. In the electronics factory room, all the main parts of the potential are equal, in order to ensure that the entire building will not generate its own countervoltage, and we can achieve the reduction of lightning electromagnetic pulse interference.

3. Anti-static grounding

Static electricity is mainly produced by the friction between different social material culture of enterprises. In the process of production and development of electronic workshop, the harm caused by static electricity is many aspects.
