Mining explosion-proof vacuum feeder switch-Bifilar cavity

The main cavity of servo feed adopts the servo motor firstly created in domestic to drive slide propulsion, reliable limit switches are installed on the back and the front side of the slide to ensure a reliable connection when the circuit breaker pushes in and a safe electrical clearance when pulls out. Double line cavity design, the circuit breaker with isolation fracture, can hand out of the movement without electricity, and circuit breaker plug with 6 wireless temperature measurement devices to real- time monitoring of temperature and early warning, which is easy to maintain and safe to operate.


Product Details

① Double line cavity design

The power supply side is separated from the load side, to ensure the absolutely safe of the load side when the circuit breaker pulls out.

② Electric propulsion and pull out function

Press the push button, the circuit breaker will move in at the same time with the slide until the static and dynamic contactor can contact with each other.

Press the pull out button, the circuit breaker will move out with the slide until it reaches a safe distance between static and dynamic contactor to ensure the load without electricity.

③ Hand-shaking device

When the feeder is under the condition of no electricity, the electric propulsion and pull out can not be used, and manually push and pull out can be used. The effect is the same as an electric device.

④ Installation of a circular observation window on the left side

Here you can see the reliability of the contact of the circuit breaker contactors, clearly observe the movement of internal circuit breaker and the contact situation of the dynamic and static contactor.

⑤ Multichannel temperature sensor

There are 6 wireless temperature sensors installed at the feeder plug to monitor the temperature in real time and to avoid high temperature of the plug due to poor contact.

⑥ The circuit breaker connects with the dynamic contactor with

the conductive block, which increases the stability of the body when the static contactor and dynamic contactor contacts.
