Title:
TEMPERATURE MEASUREMENT PLUG USED IN COOPERATION WITH RING MAIN UNIT PLUG TEMPERATURE MEASUREMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/037078
Kind Code:
A1
Abstract:
A temperature measurement plug used in cooperation with a ring main unit plug temperature measurement system, comprising a plug body (100), one end of the plug body (100) being provided with a main insert mounting groove (110); a main insert (200) provided in the main insert mounting groove (110), the main insert (200) being used for assisting the plug body (100) in mounting; and a passive wireless temperature measurement chip (300) provided in the plug body (100) and used for measuring the internal temperature of a ring main unit, feeding back a temperature signal to an external receiving antenna, and generating a working power supply by sensing an external electromagnetic wave signal. Compared with the conventional structure of an upper inlay and a lower inlay, the temperature measurement plug greatly reduces the number of metal inserts and reduces costs. The internal temperature of the ring main unit can be measured by means of the passive wireless temperature measurement chip (300); meanwhile, a power supply for working can be directly obtained by sensing the external electromagnetic wave signal， and it is unnecessary to obtain the power supply by means of self-fetching power or electric field coupling power fetching, and other modes, which greatly prolongs the service life.
