1. System Overview
Mine flameproof vacuum feed switch (hereinafter referred to as feed switch) is mainly used in coal mines, in the line of AC 50Hz, voltage to 1140V, rated current of 400A, 500A, 630A, 800A, as the total power supply system Switch, branch switch, or as a feeder switch for mine explosion-proof mobile substation (open the back cover and dock with the mobile substation), can also be used as a large-capacity motor infrequent start. It has functions of overload, short circuit, undervoltage, leakage protection (selective leakage protection) and leakage blocking. The product can be used in mine explosion-proof vacuum feed switches and other coal mine safety electricity monitoring systems.
2. System configuration and function realization
1. KBZ630Z control system hardware configuration
Display: A 4-line Chinese character display with IP65 protection level,
Programmable controller: UN200 series CPU224Q UN 214-1AF23-0XB0 one
Expansion module: three-phase AC and leakage monitoring module UN 231-0BH22-0XA0
(Note: KBZ800Z requires two three-phase AC and leakage monitoring modules)
2. System architecture
The system is composed of a set of UniMAT PLC + text screen control system and vacuum breaker execution system. as the picture shows. Among them, the CPU performs some logic control. The mining module mainly collects AC voltage, current, and leakage resistance signals to achieve system monitoring and monitoring and complete protection functions such as leakage blocking, overload, short circuit, phase failure, undervoltage and overvoltage. It has the advantages of high intelligence, stable performance and reliable operation.
