Large-current connector safety monitoring method

Abstract

The invention discloses a large-current connector safety monitoring method, and belongs to the technical field of electrical engineering. The large-current connector safety monitoring method is characterized in that: a temperature sensor is arranged in a plug or socket of a large-current connector, and a safety monitoring control system uninterruptedly acquires signals of the temperature sensor and sends the signals to a signal processing module; the signal processing module analyzes and calculates the signals to output real-time temperature T; an overtemperature judgment module judges whether the connector is overheat according to the temperature T, sends an overtemperature signal if the T is greater than set temperature, and does not send the overtemperature signal if the T is not greater than the set temperature; and an alarm execution module starts an alarm device and immediately cut off a power source after receiving the overtemperature signal. The large-current connector safety monitoring method has the advantage of eliminating potential safety hazards such as interface burning due to heat generation of the plug and socket when the large-current connector works, and even electrical fire.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering and relates to a safety monitoring method, in particular to a safety monitoring method of a high-current connector. Background technique [0002] At present, high-current connectors have been increasingly used in electrical engineering, automotive engineering and other fields. However, in the process of use, long-term plugging and unplugging of connector plugs and sockets will inevitably cause wear and tear on the plugs and sockets, and loosening will occur, resulting in a decrease in contact pressure and an increase in contact resistance; Moreover, dust, oil stains, etc. will also deteriorate the surface finish, resulting in a smaller effective contact area and an increase in contact resistance. Because the high-current connector has the characteristics of long working time, high voltage and large current, the increase of contact resistance will cause the plug and socket to heat u...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: when the high-current connector is working, the contact resistance increases due to factors such as poor contact of the plug and socket or poor surface finish, which in turn causes the plug and socket to heat up and cause safety hazards. A safety monitoring method for high-current connectors. By installing a temperature sensor in the plug or socket, the working temperature of the connector is continuously monitored in real time. When the set temperature threshold is exceeded, an alarm device is activated and the power is automatically cut off.
