Abstract

The invention belongs to the technical field of low-voltage electrical equipment, and particularly relates to a molded case circuit breaker. Comprising a metering unit, a processing unit, a voltage acquisition unit, a tripping unit and a current acquisition unit, and the voltage acquisition unit is used for acquiring voltage on a phase line and generating a voltage signal; the current acquisition unit is used for acquiring current on a phase line and generating a current signal; the metering unit can calculate the electric power data according to the current signal and the voltage signal, and when the calculated voltage value exceeds a set range, a second tripping signal is generated; the processing unit can compare the current signal with a set protection threshold value, and generates a first tripping signal when the current signal exceeds the protection threshold value; the tripping unit can control the opening and closing state of the tripper structural member according to the first tripping signal and the second tripping signal. According to the invention, the control precision is improved, and data acquisition, electric energy measurement, power measurement, harmonic measurement and temperature and humidity measurement are realized through the metering module.

Description

technical field [0001] The invention belongs to the technical field of low-voltage electrical equipment, and in particular relates to a molded case circuit breaker. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. The current is automatically cut off after the trip setting is exceeded. The plastic case refers to the use of plastic insulators as the casing of the device, which is used to isolate conductors and grounded metal parts, and its auxiliary contacts, undervoltage releases and shunt releases. More modularization is used. The traditional molded case circuit breaker is a thermal magnetic protection, which triggers the tripping by deforming the bimetal strip through the heating of the thermal element under the current. data. Contents of the invention [0003] The utility ...
