DSN-BMZ/Y Electromagnetism Lock with Switchgear equipment
The old type of high-voltage electric display device with mandatory electrical latching, which is too simple in principle, consists of half wave rectifying and directly combining the signals from the A, B and C phase sensors to control the latching circuit. In this way, when the system has an anomaly of single phase grounding or absence phase, the drift of the locked-in control voltage can lead to the accident of the electrically connected grounding switch. Most of the neon high-voltage electric display devices installed in the project are made of plastic cases and are installed in the space between high-voltage devices.
Once a short circuit is released inside the switchboard in the course of operation, the high temperature arc may melt the plastic cases of the devices and injure the operators or maintenance personnel. The standard medium cabinet is high and low structure, front side height is 2300 mm, back side height is 2000 mm; And the contour structure is consistent. Gaodigui's busbar is arranged like a grain, and the instrument room is a separate structure, detachable. The contour cabinet busbar is arranged in a vertical zigzag, and the instrument room and the cabinet body are integrated. The same height structure has larger mounting space than the high and low structure, and is also convenient for production and operation maintenance.
