Abstract

The invention relates to an intelligent wireless temperature-detecting device for a breaker contact. The device is of ring shape and comprises a base (1) and a rear cover (9) in matching connection with the base (1), wherein the interior of the base (1) is a cavity; a slot (1.1) is arranged on an annular inner wall; the number of the slot (1.1) is at least three; one slot (1.1) is provided with aheat conducting plate (8); two slots (1.1) are provided with an eccentric positioning tile (3); the front end of the eccentric positioning tile (3) is extended out of the slot (1.1) while the rear end thereof is arranged in the cavity of the base (1); a compression spring (2) is mounted in the cavity of the base (1) and is arranged on the tail end of the eccentric positioning tile (3); the front end of the heat conducting plate (8) is extended out of the slot (1.1) while the rear end thereof is connected to one end of a sensor (7); the other end of the sensor (7) is connected to one end of a MCU control unit (6); and the other end of the MCU control unit (6) is connected to a RF wireless data transmission module (4). The device can be mounted on a static contact of the high-pressure shafts, has long service life and can precisely detect the temperature of the contact.

Description

(1) Technical field [0001] The invention relates to an intelligent wireless temperature measuring device for circuit breaker contacts, which is mainly used for online measurement of the temperature of key points of static contacts, and uploads the data to a temperature measurement communication terminal in a wireless manner, so as to realize the display of measured values ​​such as temperature and overshoot The utility model belongs to the field of electromechanical technology, which can limit the alarm and eliminate hidden dangers of accidents in time. (2) Background technology [0002] In the power system, especially in the high-voltage power system, heating accidents at the moving and static contacts of electrical equipment occur frequently. Such accidents not only seriously affect the normal operation of the power system, but also cause staggering economic losses. [0003] Electrical equipment in operation usually works in a state of high voltage and high current, and so...
