The invention relates to a pollution and torque measuring device for busbar additional connection modules.
In particular, the invention relates to a pollution and torque measuring device for busbar additional connection modules that detects the degree of pollution occurring in the additional connection modules that allow busbar modules to be attached to each other in electrical distribution systems known as busbars and whether the additional is tightened with sufficient torque.
In today's energy distribution systems, modular compact conductors called busbar are used. Each conductor called busbar is more preferred because it has structures with a high current carrying capacity.
Electrical distribution and transport systems known as busbar are modular. Each busbar module is attached to the end of the line according to the route of the electrical line and forms the electric transport line. The modules are connected to each other by means of the so-called additional module.
The busbar add-on module connects the conductor rods in the busbar modules electrically and mechanically to each other and allows the line to continue.
In busbar electrical distribution systems, it is of great importance to check the mounting accuracy of the additional module that allows busbar modules to be attached to each other.
After the said additional connection module joins the two busbar modules, its assembly is completed by tightening it with the help of a bolt. If the said bolt is not tightened at sufficient torque, loosening and thus energy transmission loss occurs over time.
In the current system, there is no system that checks the accuracy of the said assembly process. During the first assembly, the amount of torque to be tightened is determined and tightened at that torque amount. However, over time there may be loosening of the bolt. It is also not easy to detect.
Another additional connection module problem is related to the detection of dust and contamination that may occur on the additional connection module.
Problems occurring in both of the aforementioned cases result in overheating of the additional connection module. However, as mentioned, this is a conclusion and energy was lost due to heating.
In the current system, temperature sensors are used to detect this temperature increase on the additional connection module. These sensors detect the increase in temperature and warn the user.
However, as a risk, the temperature sensors cannot do what is desired due to the system not being heated sufficiently before and during commissioning, so the system cannot be controlled well. In other words, the said heat sensors are not able to detect when the problem begins to occur, that is, when contamination or loosening begins. As a consequence of the problem, it began to detect when warming occurred, and that moment is too late for return.
In the literature, Korean patent application No. KR20170001197 also relates to the subject matter “The present invention relates to an apparatus to monitor a temperature of a switchboard capable of preventing fire by detecting a temperature of a connection unit or a busbar in the switchboard in real time.
