Problems solved by technology

However, the disadvantage of this method is that although the external temperature of the air circuit breaker is measurable, its internal temperature is difficult to measure
[0011] Installing a temperature sensor to detect the temperature of the conduction unit of the air circuit breaker can be considered as a feasible solution, but it is not so easy to install the temperature sensor at the upper and lower terminals where the current flows, so that there is no installation that can Air circuit breaker with temperature sensor that detects abnormal heat generation in real time

Abstract

The air circuit breaker having a temperature sensor comprises: a temperature sensor sensing a temperature by being inserted into a sensor insertion hole formed the base mold; and a temperature display indicating a value detected by the temperature sensor as a temperature of the conduction unit, whereby the temperature inside the breaker is always monitored to prevent the damage caused by over-heating of the conduction unit.

Description

technical field [0001] The following description generally relates to an air circuit breaker having a temperature sensor capable of detecting the temperature of the air circuit breaker by connecting movable contactors and fixed contactors, thereby preventing damage caused by a conduction unit including a current conduction circuit. Damage to the air circuit breaker caused by abnormal heat. Background technique [0002] Generally, a circuit breaker is an electrical protection device installed between a power source and a load unit to protect load units such as motors, transformers and transmission lines from Generated abnormal currents (i.e. large currents caused by, for example, short circuits and ground faults). In addition, a circuit breaker that is insulated by insulating at the circuit breaker can manually open or close the transmission line under normal use conditions, open or close the transmission line from a distance using an electrical operation unit outside the me...
