Detailed explanation of the pulse electronic fence national standard lightning protection installation process

Modern perimeter intrusion security systems are susceptible to lightning weather, causing the system to not work stably or even be damaged. Good grounding of the system is regarded as an effective solution for the lightning protection system of the equipment, which has become an important task in engineering installation. However, how to distinguish the grounding effect? Is the role of grounding just lightning protection so simple?
Pulse electronic fence system grounding effect
For the pulse electronic fence system, the grounding device is mainly composed of the grounding body and the grounding wire. The two are installed together to complete the front end fence and the pulse host grounding construction. According to the grounding purpose, the grounding can be divided into protective grounding and working grounding.
1, protective grounding
The so-called protective grounding is a technical measure to prevent personal electric shock accidents and ensure that the pulse equipment is not damaged. It can also be divided into lightning protection grounding and chassis safety grounding.
One end of the arrester is connected to the pulse front end alloy wire, and one end is grounded. Whether it is direct lightning strike or lightning electrostatic induction, electromagnetic induction and lightning wave intrusion, lightning current can be sent to the earth through lightning protection grounding to avoid the pulse system suffering from instantaneous high voltage electric shock. , the case of damage to the pulse master.

The safe grounding of the casing is to ground the casing of all metal equipment under the conventional mains power supply system. The pulse electronic fence system is mainly for grounding the pulse box rainproof box. First, to prevent the accumulation of electric charge on the rain box casing, static electricity is generated. Discharge may affect the safety of the main unit and personal safety. Secondly, in order to prevent damage to some of the live electrical insulation materials or other circumstances, the unpowered parts are charged, which is a way to protect personal safety.

2, work ground
For the pulsed electronic fence system, the working grounding is mainly a technical means to ensure the stable implementation of the host function.
Among them, good grounding effect is an important factor to realize the reliable "touching net" function of the pulse host. At the same time, the standard working grounding installation also ensures the stability of the circuit system work, and cooperates with the host to resist the external electromagnetic field interference, which can effectively solve the problem that the pulse products in the substation and the like cannot work normally.
The grounding effect of the pulsed electronic fence system is obvious. In the engineering installation and construction, the grounding work is very important, combined with the technical advantages of the pulse products, to ensure that the entire pulsed electronic fence can operate normally and stably under complicated conditions.
Poor grounding effect of pulse system causes multiple device problems
The grounding technology is applied to the weak current system of the perimeter alarm pulse product, which can effectively improve the stability of the equipment in complex environments. At the same time, in the lightning weather, it also shoulders the functions of protecting personal safety and protecting the host equipment. However, the unreasonable grounding technique, which causes the difference in grounding effect, will directly affect the normal use of certain functions of the pulsed electronic fence system.
First, the grounding technology is one of the important contents of the electromagnetic compatibility technology of power electronic equipment, and is also applicable to the pulse electronic fence system. Good grounding technology allows current to pass through the grounding wire and is compatible with the earth without voltage drop. However, due to unreasonable grounding, electromagnetic interference, such as common ground interference and ground loop interference, may be introduced, resulting in an electronic fence. The equipment does not work properly under electromagnetic field and lightning weather conditions.
Secondly, the pulse electronic fence integrates the new alarm concept of deterrence, blocking and alarm. When there is an intruder's invasion, the high-voltage pulse electricity blocks the intruder with high-voltage pulse electric shock without affecting the intruder's personal safety. The bad pulse host is grounded, and when a person touches, a complete current loop cannot be formed. After the current is suspended, the electronic fence is weakened, and the intruder is less difficult to climb. In addition, the grounding effect is not good, and the voltage of the front fence alloy line fluctuates. And not uniform.

Good grounding, fence forming loop, strong combat
Third, when the pulsed electronic fence is in lightning weather or equipment failure, the protective grounding bears an important duty to ensure personal safety and equipment safety. Without good grounding effect, safety hazards will occur.
Obviously, the grounding effect of the pulsed electronic fence system directly affects the stable and safe operation of the system. How to carry out standardized grounding installation, how to adjust the grounding according to local conditions, and how to evaluate the grounding effect are all urgent problems for engineering operators.

Plasma Cutting Machine


What are CNC Plasma Cutting Machines?


Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, Stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well. Plasma cutting is often used in fabrication shops, automotive repair and restoration, industrial construction, and salvage and scrapping operations. Due to the high speed and precision cuts combined with low cost, plasma cutting sees widespread use from large-scale industrial CNC applications down to small hobbyist shops. CNC cutting machines, such as CNC plasma cutting machines, utilize their intricate software systems and components to efficiently, accurately and smoothly handle plasma cutting processes.


CNC Plasma Cutting vs. Other Cutting Methods:


Of course, plasma cutting is only one variety of system which CNC machines may be designed to work with. Another common variety is the CNC waterjet cutter. Waterjets can use either a mixture of pressurized water and abrasive, or purely water. One benefit to a waterjet cutter is that there`s no HAZ, or heat-affected zone, which can alter a material.
Another cutting method utilizing CNC machines is oxy-fuel, using fuel gases and oxygen, which dates back about 100 years. Here, a stream of oxygen is blasted onto a metal heated to kindling temperature, turning it into a flowing metal oxide.
With CNC plasma cutting machines, a plasma torch blows an inert gas at high speeds out of a nozzle, through an electrical arc, which turns some of that gas to plasma.

While all of these options remain widely used today, CNC plasma cutting machines are typically seen as a solution for manufacturers who are concerned with quickly and efficiently cutting conductive materials up to 3″ thick. The CNC plasma cutting process has superior cutting speeds, piercing speeds, and generates very precise cut qualities. More speed and higher quality also produces superior efficiency and productivity.


Cnc Plasma Cutting Machine applications:


It is widely used in the process of cutting metal plates in the machinery manufacturing industry, engineering industry and metal fabrication and can cut mild steel, stainless steel, aluminium, copper and many kinds of non-ferrous metal.
