Product Description
Mining Explosion-proof Vacuum Feeder Switch is for mine use.
Mining Explosion-proof Vacuum Feeder Switch
Use
KBZ-200/1140II, KBZ-400/1140(660)II mining explosion-proof vacuum feeder switch is used in coal mines containing explosive gas(methane) and coal dust for three-phase isolated neutral power supply system with AC 50Hz, rated voltage 1140V, and rated current to 400A(200A). It can be used as master switch or sub-switch in the first or the end slip distribution, can be used as it low-fed by docking with the mobile substation.
Function Features
It is uesd in coal mines for three-phase isolated neutral power supply system with AC 50Hz, rated voltage 1140V(660V) and rated current to 200A, 400A, It can be used as matser switch or sub-switch of power distribution system or used to control infrequency high-capacity starter.
The protection system, adopting advanced DSP microprocessors and high-capacity new chip for two-chip working, equipped with high-precision data processing and advanced protesting algorithms has high precision of protection and fast response. It can complete a number of protection functions such as overload, short circuit (inluding phase-sensitive protection and current amplitude protection), leakage atresia, leakage protection, selective leakage protecion, undervoltage, three-phase imbalance, phase breaking, temperature protection, gas protection, wind power atresia, power measurement etc. Besides, it is possible to customize to the manufactures the live side-load instructions, communication network, power-off atresia etc.
