Unit Definition

Product Characteristics

Operation Safety:

Through the following security measures, we can provide users with special security:

Integrated Three-station Load Switch

The circuit breaker adopts the load switch instead of the isolation switch, which is safer and more reliable. The fully sealed design of the primary side provides protection against accidental contact. The mechanical interlocked live display can provide the live indication of the line in and out. Equipped with silicone rubber cable plug, the cable head is fully insulated and sealed, so that it is not affected by dust, moisture, small animals and other external environment spring energy storage operating mechanism, manual or electric operation panel analog diagram provides switch position indication cabinet made of galvanized sheet, surface electrostatic spraying, enhance corrosion resistance Pressure gauge monitors the safe pressure range of SF6 gas in the box.

Economy:

maintenance-free

Highly reliable

Flexible Solution:

A variety of wire approach, can achieve a variety of combinations of left, right, up or forward lines, can achieve any combination among the units by using insulated bus, can realize the front and back cabinets or left and right cabinets and design scheme flexible.

Widely Used:

Large feed capacity, small footprint, suitable for a variety of applications.

Auxiliary Equipment Parameter

Note: (1) Depends on the current rating of the fuse.

Design Specification

SRM □-12 Fully enclosed fully insulated inflatable ring network switchgear is mounted on a galvanized sheet frame with the switch unit in an SF6 air box made of corrosion-resistant and non-magnetic 3mm thick stainless steel plate. The SF6 gas box is a "sealed pressure system" that operates under normal operating conditions. SF6 gas normal working pressure is 0.015~0.04MPa. The gas box is equipped with a pressure release device to ensure that the gas can be released from the bottom or rear when the pressure is too high.
