Document Type and Number:
WIPO Patent Application WO/2017/140107
Kind Code:
A1
Abstract:
Provided is a circuit-breaker temperature acquisition device, comprising a sensor (1), a current transformer (2), and a busbar (3); said current transformer (2) is provided with a mounting through-hole (210) used for mounting the busbar (3); the busbar (3) is arranged to pass through the mounting through-hole (210). The sensor (1) is mounted inside the current transformer (2) and arranged opposite to the busbar (3) in the mounting through-hole (210); the current transformer (2) is provided with a contact tab (4); said contact tab (4) is connected to both the sensor (1) in the current transformer (2) and the busbar (3) in the mounting through-hole (210); the sensor (1) acquires the temperature on the busbar (3) by means of the contact tab (4). Provided is a circuit-breaker temperature acquisition device that measures accurately, is simple to install, and has stability in operation.
