KBZ Mining Explosion-proof Vacuum Feeder Switch

1)as branch swithc
2)diod indication
3)with kinds of protective functions
4)function of wind power methane interlock

 Purpose

KBZ16- / 1140 (660) Y explosion-proof vacuum feed switch for mine is suitable to the mine well with mixed gas containing methane. explosion-proof vacuum feed  switch for mine is suitable to the mine well with mixed gas containing methane.

 In the power supply system of 50 Hz AC, rated voltage of 1140 V and below and the triphase neutral not grounding, the product can be used as distribution main switch alone ,distribution branch switch and also the control of motor not start frequently .

The switch connects with KJ254 mine system of power automatic control and synthesis  monitoring to achieve remote automatic control and monitoring of equipment ,at last ,to achieve nobody is on guard of monitoring.

Technical Features

1) With the display of closing, opening, fault and insulation resistance of kilohmeter;

2)Times of overload and short circuit can be adjustable by DIP plug;

3)with the protective functions of short-circuit, overloading, current leakage interlock, triphase symmetry current leakage, selective current leakage,branch switch current leakage;

4)With the function of wind power methane interlock.
