The unique multi-layer annular pole surface structure is adopted to make the contact area between the sealant and the pole pole large. The triple sealing technology ensures the safety and reliability of the seal.

Adopting unique labyrinth pole structure and multiple sealing technology to ensure safe and reliable sealing.

The sealing reaction efficiency is high, and there is no need to add water and acid during the whole use process.

This special battery and the explosion-proof special power supply device composed of the battery and the power supply are suitable for various types of mine explosion-proof special battery-type electric locomotives and refuge shelters.

The unique structure and multiple sealing technology can ensure that the battery does not leak electrolyte under vibration.

　　Features:

　　1. Various control methods such as static electricity, charging, discharging, and reverse charging can be realized

　　2. Pulse width/pulse amplitude can be set to realize pulse charging

　　3. It has multiple working modes such as constant current, constant voltage, constant voltage cross current, constant current limit voltage charging, constant current discharge, etc.

　　4. With fixed time, voltage and other stage conversion methods to realize automatic conversion

　　5. With power-down storage function, the incoming call will automatically return to the working state before power-off, realizing unattended

　　Features:

　　1. The power train cabinet can be equipped with a current monitoring and alarm device, which can provide an intelligent communication interface and corresponding management software to facilitate centralized monitoring and management of the computer room.

　　2. "Three remotes" can be realized, namely remote measurement, remote signaling, and remote control.

　　3. The power train cabinet can monitor the total input current, voltage, fault of each circuit, the status of each output branch switch and the power quality (optional),

　　And in a visual and intuitive way (such as LCD, LED, etc.) to centrally display the refresh rate, not less than once per second.

　　4. The column head cabinet can be operated on the front or on both sides, and can enter and exit the line up and down. You can choose to have a busbar room or without a busbar room. Outlet terminals can be installed in the busbar compartment.

Features:

1. Reasonable distribution of electric energy

2. Convenient to open and close the circuit

3. It has a high level of safety protection and can visually display the conduction state of the circuit.
