Detailed Description
KBZ-630、500/1140(660)Mining flameproof vacuum feed switch
use
KBZ-630、500/1140(660)Mining flameproof vacuum feed switch, adapted to the coal mine ac 50 hz, voltage 1140 v, rated current 630 a line, as the power distribution system of the main switch or separate customs use; When this switch is used as a master switch, also can be used as a mining flameproof vacuum feed switch on the low voltage side of mobile substation.
The main functions and features
1, the switch adopts intelligent computer protection device, the display in Chinese, can not open the door for each parameter setting. With short circuit, over current, the leakage, leakage atresia, undervoltage, wind power atresia, over voltage protection functions such as simulation test, can be 100 times the cause of the problem and the time of memory, can record 1 million times close break-brake, can set the password, to prevent the non-professional workers wrong operation, has the clock function, can be got behind 2-999 switch network, achieve coal mine "remote", "remote inspection", "remote control".
2, the structure of the shell open the door for translation type fast.
3, ontology is draw-out type structure, easy maintenance.
4, the RS485 communication interface, can realize the coal mine "three remote" function.
5, can choose PLC programming controller.
