Problems solved by technology

[0005] In order to be able to effectively control the opening and closing of the vacuum circuit breaker, it is mainly driven by the drive rod on the permanent magnet mechanism. How to effectively control the permanent magnet mechanism, when the circuit breaker is closed and opened, its The contacts are charged with strong electricity. The most effective way is to cut off when the bus voltage crosses zero. However, the existing controllers are not highly intelligent, so it is necessary to design an effective controller to meet the site environment, Equipment condition and job requirements

Embodiment

[0069] Example: such as figure 2 As shown, the single-chip microcomputer adopts the PIC16F877 model, and the PIC16F877 itself has 8 A / D input channels, and they share a 10-bit ADC module. The shortest time for the ADC module to complete a 10-bit data conversion is 19.2 microseconds, and the interval between two conversions is at least 3.2. 16F877 can provide 16 A / D input channel combinations, and 0-8 pins can be set by controlling the internal register ADCON1 The pin is used as an analog signal input channel, and 16F877 also supports an external reference voltage to improve the resolution of A / D conversion.

[0070] The signal conditioning circuit is coupled to the transformer to condition the detection signal and output an analog signal; the photoelectric isolation circuit couples the analog signal to the power factor module, overload judgment circuit, and zero-crossing detection circuit respectively; the power factor module uses Convert the analog signal to calculate the p...

Description

technical field [0001] The invention relates to a high-voltage vacuum permanent magnet circuit breaker, in particular to an intelligent controller. Background technique [0002] Traditional high-voltage vacuum circuit breakers can be divided into electromagnetic type and electric spring type according to their operating mechanism. In the early days, the electromagnetic operating mechanism catered to the needs of vacuum interrupters and was widely developed and applied. However, due to Its mechanical structure is complex and has a high failure rate, so it is replaced by the emerging permanent magnet operating mechanism. The permanent magnet mechanism mainly uses the magnetic force of the permanent magnet to keep the circuit breaker in the open or closed position. The circuit breaker with permanent magnet mechanism can be combined with computer technology to facilitate the intelligent operation of circuit breaker control. [0003] permanent magnet mechanism such as figure 1...
