摘要： An electronic circuit breaker comprises an electronic circuitry and a lockout mechanism configured to provide a safety feature. The lockout mechanism includes a trip rod placed along a longitudinal axis of the electronic circuit breaker. The trip rod has first and second ends. The lockout mechanism further includes a barrel mounted coaxially around the trip rod near the first end of the trip rod. The lockout mechanism further includes a moving arm mechanically coupled to the trip rod. The lockout mechanism further includes an electronic-powered magnet mounted coaxially on the trip rod near the second end being opposite of the first end of the trip rod. The lockout mechanism further includes an armature mechanically coupled to the trip rod. The barrel serves to block the moving arm and the trip rod is pushed by the electronic-powered magnet to interact with the barrel to remove a lockout such that the electronic-powered magnet is activated to push the trip rod to pull on the armature, causing the electronic circuit breaker to be tripped.

摘要： A temperature sensor of a thermal monitoring system is provided for use in power distribution systems. The temperature sensor comprises ceramic printed circuit board (PCB) and a terminal. The ceramic PCB includes a temperature sensing element disposed on a side of the ceramic PCB. The terminal is configured to be fixed directly in contact with a measured point and is directly in touch with the ceramic PCB such that heat is conducted from the terminal, through the ceramic PCB and then to the temperature sensing element. The temperature sensing element is configured to generate an electrical signal in response to the heat such that the electrical signal is sent through a pair of lead wires to a controller for monitoring a temperature. The temperature sensor further comprises an epoxy to seal a portion of the terminal, the ceramic PCB in its entirety and a portion of the pair of lead wires to ensure a desired physical strength and a desired dielectric strength.
