Title:
端子過熱検出装置
Document Type and Number:
Japanese Patent JP7070942
Kind Code:
B2
Abstract:
To provide a terminal overheat detection device capable of detecting abnormal overheat of a terminal by simple configuration, without requiring modification of a circuit breaker, and yet capable of confirming whether or not a 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 and displaying the temperature of the terminal, 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 displacing reciprocally in response to the reaction, and a signal output part to which displacement of the displacement transmission part is transmitted, and being driven when a prescribed level is exceeded, where the connection is located between the terminal and the wire 3 for connection therewith, when the terminal overheat detection device is attached to the circuit breaker.SELECTED DRAWING: Figure 1
