Abstract

The invention discloses a distribution isolation switch on-line monitoring system for a kiln. The system comprises a current transformer, a combustion working condition sensor, infrared temperature sensors, a current signal conditioning module, a combustion state conditioning module, a data acquisition module, a frequency tracking module, a microprocessor module, a data storage module, a communication module, and a display module. The current transformer is connected to the current signal conditioning module. The combustion working condition sensor is connected to the combustion state conditioning module. The current signal conditioning module and the infrared temperature sensors are connected to the input port of the data acquisition module. The input end of the frequency tracking module is connected to any output port of the current signal conditioning module. The frequency tracking module is connected to the microprocessor module. The combustion state conditioning module, the data acquisition module, the data storage module, the communication module and the display module are connected to the AD port, data line, address line and control line, GPIO port and asynchronous serial interface of the microprocessor module. The online monitoring problem of isolation switch contact temperature, passing current and combustion state is solved.

Description

technical field [0001] The invention relates to the technical field of high-voltage power supply for industrial kilns, in particular to an on-line monitoring system for power distribution isolating switches for kilns. Background technique [0002] High-yield, high-efficiency, comprehensive mechanized and automated kiln combustion production put forward higher requirements for the continuity, reliability and safety of the kiln power supply, especially the high-voltage power supply line that supplies power to the main fan of the kiln, and its power supply continuity directly affects Safe production of kilns. The isolating switch in the high-voltage power distribution device used in kiln combustion production is an important part of the high-voltage power supply system, which plays the role of isolating or connecting high-voltage lines, and its operating status is related to the stability of the terminal load power supply. The high-voltage power distribution isolating switch f...
