Mine DC line automatically stops transmission switch function：
1. Isolating switch function: partition switch main contactor using quadruple switch,switch distance up to 8 cm, high dielectric strength, small leakage current, isolate power supply circuit effectively.
2. Automatic tripping functions: internal partition switch with over-load trip and short-circuit electromagnetic tripping device, can automatically cut off the fault line. Tripping component optional: 100A, 150A,180A,200A,225A,400A,
600A.
3. Manual switch with break-brake function: partition switch equipped manual operating handle, can be connected with load and breaking power lines.
4. Charged indicator function: when dc overhead lines have electricity, after partition switch is closed, partition switch load side charged light turn on, indicating switch load side take power. When the switch points, light turned off.
5. Tidal displacement function: internal partition switch ,have drive circuit, in damp environment, drive tide interior guarantee moist air cannot invade the switch circuit, ensure the partition part of the electrical insulation strength of the switch.
