A flexible passive label, a passive flexible temperature measuring device and a wireless power supply networking temperature measuring system

Abstract

The invention discloses a passive flexible label, a passive flexible temperature measuring device and a wireless power supply networking temperature measuring system. Passive flexible tags include a flexible housing, a flexible printed circuit board, and a temperature sensor to detect the temperature of the switchgear contacts. The passive flexible temperature measuring device includes a passive flexible label and a body, the body is a flexible strip, the flexible passive label is fixed on the body, and the passive flexible temperature measuring device is installed at the joint between the plum blossom claw of the moving contact and the contact . The wireless power supply networking temperature measurement system includes at least one wireless power supply and at least one passive flexible temperature measurement device, and each wireless power supply is networked with at least one passive flexible temperature measurement device to transmit radio frequency signals; within the same network Radio frequency signals can also be transmitted between temperature measuring devices and wireless power supplies to form an intelligent sensor network to monitor the temperature of multiple points.

Description

technical field [0001] The invention relates to the field of switch cabinet temperature measuring devices, in particular to a flexible passive label adopting passive power acquisition, a passive flexible temperature measuring device installed on a moving contact, and an ad hoc network temperature measuring device using electromagnetic waves for wireless power supply system. Background technique [0002] High-voltage switchgear is an important electrical equipment in power plants and substations. At present, high-voltage switchgear generally adopts plug-type connection. During long-term operation, it is easy to generate heat due to long-term overloading of contacts or bus bar connections, loose joints, and aging of contacts, resulting in increased contact resistance and heating of contacts or bus bars. The temperature of the row connection will rise, which will lead to a further increase in its contact resistance, forming a vicious circle, and eventually causing the switchge...
