MNS low-pressure cabinet of drawers is an integrated combination, its safety protection function should be analyzed from different parts. So how about the protection function of the MNS low pressure chest of drawers shell? Today from the shell analysis.
Internal safety of power distribution cabinet system: the upper part of the cabinet is the bus room, the front part is the electrical room, and the back part is the cable inlet and outlet room. There are steel plates or insulation plates between the rooms to ensure safety.
Personal safety: The door of the MNS low-voltage cabinet compartment is mechanically interlocked with the operating handle of the circuit breaker or disconnector. The door can only be opened when the handle is in the disconnecting position.
High short circuit self-protection: the horizontal bus adopts the horizontal arrangement after the cabinet, in order to enhance the anti-electric power ability of the bus, which is the basic measure to make the main circuit have the ability of high short circuit strength.
Busbar self-protection: busbar is protected by high-strength flame-retardant plastic functional board with high insulation strength, which has anti-fault arc performance and makes operation and maintenance safe and reliable
Module design protection: using standard module design, respectively can be composed of protection, operation, conversion, control, adjustment, measurement, indicating and other standard units, can be arbitrarily assembled according to requirements.
Cabinet inside and outside isolation protection: MNS low-pressure drawer cabinet adopts high-strength flame-retardant engineering plastic, which effectively strengthens the protection and safety performance; And the cabinet can be selected according to the different requirements of the working environment to match the level of protection.
How does the MNS low pressure chest of drawers protect the casing? The safety protection function is very powerful, of course, we also need to know more about the safety protection function of other components of the cabinet. To learn more, visit www.tongyuhengcheng.com.
