With the continuous progress of automatic industrial control system, safety has also become a problem that people attach great importance to, especially in the power system, whether production safety or personnel safety, all kinds of original accessories are needed to provide protection. Today, a safety element is introduced,Finder safety relay。
Safety relay is also a kind of electrical appliance, but its responsibilities and functions are different from other electrical appliances. I think it is very intelligent, because it is fully automatic in terms of switching and regulation. Its composition is very simple, generally composed of four parts. Moreover, there are many kinds of safety relays, with high self-control ability, and electricity safety. It is also widely used, especially in the power system, finder safety relay has obvious advantages.
In terms of working principle, finder safety relay is composed of several relays and circuits. In order to complement abnormal defects, correct and complete relay functions are realized with low misoperation, so that the lower the error and fault value, the higher the safety factor. Therefore, it is necessary to design a variety of safety relays to protect different levels of machinery, and the main goal is to protect machine operators exposed to different levels of danger.
What is the main difference between finder safety relay and general relay? The so-called "safety relay" is not a "fault free relay", but a conventional action when a fault occurs. It has a forced guide contact structure, which can ensure safety even if the contact is fused, which is completely different from general relays.
Finder safety relay plays a role of safety protection when we use electricity, and is widely used in some high-end manufacturing industries and power industries. Because large factories use a lot of electricity, the factory itself has a lot of wires and cables, and there are also many lines. Safety relays need to be installed for regulation to ensure the power consumption of the factory. It is necessary to use relays in the power industry. If you want to output current, you must ensure the safety of the power plant itself.
Nowadays, the industrial control industry cannot do without the control of electrical power on mechanical equipment, and the safety relay not only ensures the industrial production efficiency, but also provides safety protection for enterprise employees. When the emergency stop is lifted, the machine cannot be restarted suddenly; When the safety circuit of the machine fails, the power supply of the machine can be stopped; When the safety circuit fails, the machine cannot start the safety switch, light curtain and other inputs to confirm the safety, and the above functions cannot be achieved. Finder safety relay has powerful function and high safety.
