I. Overview

FLN36-40.5D/T630-16 indoor sulfur hexafluoride load switch and FLN36-40.5D/125-31.5 indoor sulfur hexafluoride load switch fuse combination are suitable for power stations and industrial electrical equipment with three-phase AC 50/60Hz ring network or terminal power supply. They are used as load control line protection for power systems. The load switch divides and closes load current, closed-loop current, no-load transformer and cable charging current; Combination electrical appliances can break any current under rated short-circuit current and are suitable for electrical equipment such as ring substations and box type substations.

II.  Working environment

Environmental temperature: -25 ° C~+40 ° C, daily average temperature: 25 ° C;

Altitude: ≤ 1000m (exceeding this value can be discussed with our technical team);

The daily average relative humidity of the surrounding air is ≤ 95%, and the monthly average is ≤ 90%;

Places without frequent severe vibrations.

III. Main features of the product

-- Double break, three station, rotating moving contact.

-- Good insulation performance, the load switch is sealed with upper and lower shells cast with epoxy resin, and filled with SF6 gas at a pressure of 0.045-0.07mpa inside. The main circuit and grounding circuit system are all placed inside the shell.

-- Good safety performance. If an internal arc occurs and there is a weak structural point at the rear of the casing, it will be blown open. Subsequently, the arc relief valve on the cabinet will be opened and the overpressure airflow will be directed outside the cabinet.

-- Both manual and electric operations are available, making it easy and reliable to operate.

-- Three phase overall installation, good periodicity, few components, easy adjustment and installation, simple and feasible. Maintenance free, long lifespan.
