Abstract

The invention discloses an accurate temperature measuring system for a high-voltage switch cabinet busbar, and relates to temperature measuring systems. The accurate temperature measuring system for the high-voltage switch cabinet busbar is put forward to solve the problem that the temperature of a busbar with a protective cover cannot be accurately detected through the method that in the prior art, the temperature of an inner contact of a high-voltage switch cabinet is monitored through an infrared temperature measuring gun. The upper control data signal output end and the upper control data signal input end of an upper controller server are connected with the upper control data signal output end and the upper control data signal input end of each upper controller at the same time. The temperature data signal output end and the temperature data signal input end of a local controller are connected with the temperature data signal output end and the temperature data signal input end of the upper controller server. The local terminal temperature data output end of a wireless temperature measuring assembly is connected with the local terminal temperature data input end of the local controller. The temperature collecting end of the wireless temperature measuring assembly collects the temperature of the high-voltage switch cabinet busbar. The accurate temperature measuring system for the high-voltage switch cabinet busbar can be widely applied to measuring the temperature of various high-voltage switch cabinets.

Description

technical field [0001] The invention relates to a temperature measuring system, in particular to a busbar temperature measuring system. Background technique [0002] With the development of electric power technology, high-voltage and ultra-high-voltage distribution networks are increasingly appearing in major power grids. As important electrical equipment, high-voltage switchgear, The resistance increases, causing overheating, and serious fire accidents. In recent years, many switchgear overheating accidents have occurred in power plants and substations, causing fires and large-scale power outages. Solving the problem of switchgear overheating is the key to preventing such accidents. [0003] At present, monitoring the contact temperature in the switchgear can effectively prevent accidents in the switchgear, but due to the high-voltage structure in the switchgear, manual inspection and temperature measurement cannot be carried out. The temperature cannot be measured from t...
