Title:
TERMINAL OVERHEAT DETECTION DEVICE
Document Type and Number:
Japanese Patent JP2020115481
Kind Code:
A
Abstract:
To provide a terminal overheat detection device capable of detecting abnormal overheat of a terminal by simple configuration, without modifying a circuit breaker, and capable of confirming whether or not normal output can be obtained by test operation.SOLUTION: A terminal overheat detection device is a terminal temperature display device attached to the terminal 12 of an electrical machine by means of a terminal screw 11 for fixing a wire 3, and includes a connection connected with the terminal and to which heat of the terminal is conducted, a thermal element having one end fastened to the connection and the other end disposed displaceably in response to change in the heat, a displacement transmission part to which displacement of the thermal element is transmitted and which displaces reciprocally in response to reaction, and a signal output part which is driven when the displacement of the displacement transmission part is transmitted, and exceeds a prescribed threshold level.SELECTED DRAWING: Figure 1
