As it is not sad, our country is in many technological areas lagging behind the west. One of these trends is the use of devices, surge protection, lightning protection (lightning protection) in various industries – from strategic defense objects to the "gentle" medical equipment. To protect the equipment and user input supply of the active equipment necessary to provide special protective devices. These devices divert surges in power lines from sensitive electrical equipment on the ground. To solve this problem, we developed a variety of technologies. Today in Russia, mainly applied as follows: Spark gaps, Parallel connection of varistors, Combination of varistors and surge arresters.
However, none of them is not optimal. Consider the problems that facing traditional techniques of lightning protection (lightning protection), Spark gaps. Despite the fact that the protective device using spark gaps can withstand high current overload, this technology has some significant drawbacks. To trigger the device to a high value transmitted by the voltage (kV), resulting in damage to the equipment being protected. The intensity of the spark that occurs during conducting state, often causes interference and leads to a malfunction of nearby electrical equipment. Residual currents lead to disruptions in power and, therefore, unpredictable in the equipment. -Parallel Connection of varistors.
These protective devices used by several varistors based on metal oxide that are connected in parallel to obtain high current values overload. These varistors have low thermal stability and are easily damaged due to thermal wear. Electrical characteristics of varistors connected in parallel are not identical, which also reduces their time service. These devices are designed to use an internal fuse, tripping a safety device with strong momentum in order to avoid ignition and explosion. -The combination of spark gaps and varistors. To improve overlooked voltage spark gaps, some manufacturers use spark gaps and varistors with the trigger circuit. Although nominally these devices can withstand stronger pulses, laboratory testing and field trials have shown that difficulties arise in connection with different time response characteristics of arresters and varistors. Several years ago, was created new concept of protective devices – surge suppression module Strikesorb. These devices are successfully withstand high current overload, repeated lightning and thunder, pulsed voltage, in This performance devices remain unchanged for several years. Strikesorb modules are used in surge suppression devices Rayvoss (UPIP), which may have different configurations and provide unparalleled lightning (lightning protection) of various low voltage electrical equipment from surges. Strikesorb modules and devices UPIP Rayvoss manufactured in production and are widely used Raycap around the world. One of the objects of these devices are complete electric installation is carried out on the production of "SPIC SZMA" under license from Toshiba. Thanks to this equipment the acquaintance of "SPIC SZMA" with products Raycap and December 2006 ACNP SZMA became the official distributor in Russia Raycap. Now and in the domestic industry has the opportunity to use the products, which trust world's leading manufacturers (Siemens, Alcatel, Toshiba, Emerson and others). Expensive equipment requires a large investment, but it can very quickly be damaged in case of lack of appropriate suppression devices Pulse voltage, resulting in revenue loss and important functions. Investment decisions on the purchase Rayvoss, based on the use of technology Strikesorb, allow customers to continue to profit at the expense of business continuity equipment during operation under various adverse conditions.
The range of products the company includes a universal AC inverter Unidrive SP for the servo and induction motors (1.5 MW), general-purpose electric Commander SK (up to 132 kW) and electric DC current (up to 3 MW), as well as DC motors and AC servo motors and. Currently, the general global trend in equipment is to increase productivity, reduce operating costs and increase reliability by using the built-in frequency converter controller and the rejection of costly external PLC. Control Techniques is a trendsetter and a clear leader in the use of "smart actuator" and dismisses the notion that high-quality solution has to be expensive. The concept of this approach for the food industry is shown in the example line baking cookies. The main task in this case is synchronize the velocity of all nodes. In this scheme, the task is implemented without an external controller-based inverter modules Unidrive SP and programs, and SM-Application, as well as the frequency converter Commander SK. Information from sensors and limit switches supplied to the controller via the Remote I / O and transferred to one of digital protocols. The software part is implemented on the base module and user application programs, SM-Application, specifically designed to meet the challenges of traffic and has a large set of standard functions (synchronization, winding, cutting, etc.), which significantly reduces development costs and programming.
Such approach is fully justified, since it allows to reduce the equipment cost by eliminating the expensive of the common controller to reduce the costs of start-up through the use of pre-engineered and transition to fully digital control system, increase flexibility and reliability, as well as reduce downtime, etc. Practice shows that a solution based on distributed control system can be significantly cheaper than traditional systems based on external PLC from leading European manufacturers, as well as to compete on price with low-cost Asian manufacturers, greatly exceeding their quality. These decisions food industry has successfully implemented many of the largest international manufacturers: Mars, Uniliver, Craft Foods, Rolton, Nestle …. And also widely used by leading manufacturers of food processing and packaging equipment.

It is known that the construction on this day, there are actively used some varieties of metal wire. Each of the applicable types of wire used in certain types of work and is different purposes. Then each of the main types painted in more detail … metal mesh. The design, built from steel rods of various lengths and a metal grid. Must take into account that the metal grid is made only at a specialized facility.
The distinguishing features of metal mesh: size and quality of bars of the cell from which it is woven. As usual, this grid is used as a fence various objects or building rabot.Setka road. Its scope – paving, asphalt, namely reinforcement. Note that the grid road, have their manufacturing technology. This product should be different strength, quality and reliability – this is achieved by means of resistance spot welding. It is very important that the grid road, carefully welded at all intersections of their rods. Is the question – Why should apply concrete reinforcement, which uses a grid road, with road construction? Thus, the road grid allows to strengthen the structure of the road, increasing its strength after pouring asphalt or concrete. Mason's net, used in construction for one key reason: along with the cement it more effectively protects and enhances the future structure of the wall or from environmental vozdeystviy.Setka welded.
This kind of Grid seems to be one of the most durable. Its durability is ensured, on the one hand, good quality rods, from which it is made. On the other hand, welding rods together along the seams as well as on intersections, ensures high wear resistance and durability of this type of grid. Just so it is very often used not only in construction but also in industry, where fully manifest their properties. Under end I would like to note that in this article have been listed and elaborated in detail all the most famous types of nets used today in construction and other industries.
