Vue d'ensemble

FLN36-12D/FL(R)N36-12D series indoor high pressure sulfur hexafl uoride load switch is a medium voltage switch equipment developed by our company with reference to international new technology and according to the relevant standards of China’s power system. Its performance indicators are in line with IEC420, 694, 129 and the national standard GB3804-2004 “3.6kV-0.5kV high voltage AC load switch”, GB1985-2004 “High voltage AC isolation switch and ground switch”, GB/T11022-1999 “High voltage switchgear and control equipment standard common technical requirements”, are the main switching components of the ring network cabinet.

The load switch is a multi-functional medium voltage switchgear that integrates gate, opening and grounding. It is fi lled with 0.05MPa SF6 gas in a fully sealed epoxy resin shell with reinforced structure, and achieves the above three functions with fewer parts, ensuring product quality and improving reliability. Maintenance-free, safe operation for more than 20 years under normal conditions.

Main Use

FLN36-12D/T630-20 indoor AC high voltage six krypton sulfur load switch and FLRN36-12 D/T125-31.5 indoor AC high voltage six sulfur load switch-fuse combination, suitable for three-phase AC 50Hz ring network or terminal power supply power station and industrial electrical equipment, As a 10Kv power system load control line protection.

The load switch divides the load current, closed-loop current, no-load transformer and cable charging current; The combined electric appliance can break any current to the rated short-time breaking current, which is suitable for ring network units, box-type substations and other electrical equipment, especially for urban residential distribution, small secondary substations, opening and closing offices, industrial and mining enterprises, large shopping malls, airports, railway hospitals, sports venues, etc.

Basic Functions And Features

• The load switch adopts double break, rotary moving contact structure, with the following three operating states: closing; Opening the brake; Be grounded.

• SF6 gas is used as arc extinguishing and insulating medium, the main circuit is sealed in the upper and lower shell cast by epoxy resin, and the electrical conductivity is not affected by the external environment.

• Good safety performance if the internal arc occurs, there is a structural weakness inside the shell, it will be blown open, and then the arc relief valve above the cabinet will be opened to guide the overpressure air to the outside of the cabinet to ensure the safety inspection of the switch cabinet.

• The load switch set gate, opening gate and grounding switch are located in one body, which is packaged in the SF6 gas epoxy resin shell. The three positions are interlocked, compact structure, high safety and reliability.

• Small size, light weight, maintenance-free, easy to operate and safe.
