Digital display type intelligent controller for plastic-case circuit breaker

Abstract

The invention discloses a digital display type intelligent controller for a plastic-case circuit breaker. The digital display type intelligent controller comprises a plurality of printed circuit boards (PCBs), an input device, an output device, a processing chip and a memory chip, wherein the input device, the output device, the processing chip and the memory chip are electrically connected through the PCBs, the input device is formed by a plurality of light touch switches, and the output device consists of a plurality of light emitting diode (LED) luminous tubes and a nixie tube. The input device of the digital display type intelligent controller for the plastic-case circuit breaker adopts a group of light touch switches for replacing an encoding switch or a potentiometer in the existing scheme, so the digital display type intelligent controller has the advantages that simplicity and reliability are realized, the energy is saved, and the environment is protected; and in addition, the output device consists of the LED luminous tubes and the nixie tube, so the digital display type intelligent controller has the advantage that the operation state of a circuit protected by the plastic-case circuit breaker can be intuitively and precisely reflected in time.

Description

technical field [0001] The invention relates to a controller on a molded case circuit breaker, in particular to a digital display intelligent controller for a molded case circuit breaker. Background technique [0002] At present, the operation mode of the intelligent controller on the molded case circuit breaker is generally to realize the parameter setting through several coding switches or potentiometers, and this realization generally has the following disadvantages: [0003] 1) The coding switch or potentiometer is a precision device, which has high requirements for the use environment. Due to the harsh environment of the molded case circuit breaker and long-term use, the coding switch or potentiometer is prone to failure, which makes the molded case circuit breaker unreliable. ; [0004] 2) The coding switch or potentiometer has high cost and complex material composition, which does not meet the current energy saving and environmental protection requirements; [0005]...

AI Technical Summary
