Summary

Six FLN36-12 type sulfur hexafluoride load switch is my company to introduce the latest international technology, and according to the relevant standards of China's electric power system developed by the medium voltage switchgear is developed, its performance fully comply with IEC and national standards, is the high voltage switch cabinet, ring network cabinet, box type substation, distribution station as the main pole the components of the ideal.

Six FLN36-12 type sulfur hexafluoride load switch is set load switch, grounding switch, isolation switch function of medium voltage switchgear on the whole, in a sealed, with reinforced epoxy resin shell structure, filled with SF6 gas 0.045Mpa, with the least element to achieve the above three functions, so as to ensure the products the quality and reliability of insulation and breaking capacity, under normal conditions can ensure the safe operation of equipment for 20 years.

Model meaning

Use of environmental conditions

A) no more than 1000m above sea level;

B) ambient air temperature: upper limit +40 C, lower limit -25 degrees centigrade;

C) relative humidity: the daily average value is not more than 95%, and the monthly mean value is not more than 90%.

D) the ambient air is not affected by corrosive gas or combustible gas, water vapor and other obvious pollution.

E) no frequent violent vibration.

Structural characteristics

1). Easy to install

The FLN36-12 SF6 load switch and combination electrical appliances are made into a unique unit type (the upper part of the cabinet body) and stacked up installation, which greatly reduces the difficulty of making the cabinet. A complete set of cabinets can be provided.

2). Three position switch, there are closing, closing, and grounding three positions.

3). The end face has an observation window, which can be used to observe the state of the main contact and the ground contact.

4). Direct air pressure type arc extinguishing mode.

5). The sealed shell is filled with SF6 gas, which is used as insulation and arc extinguishing medium.

6). The switch has the inflatable nozzle, and the safety pressure relief valve, and can choose the gas barometer with SF6 gas.

7). Manual and electric operation can be selected.

8). Anti harsh environment, through condensation and contamination type test.

9). Optional shunt coil or overcurrent tripping device (and use).

10). Optional auxiliary switch, 1 open and 1 closed and 4 open and 4 closed.

11). Optional cabinet interlock.

12) can be charged on the operation panel. The optional pluggable display device.

13). According to the national standards of GB3804 and GB16926.

Operating mechanism

The switch of the 1. switch is realized by operation mechanism. The mechanism spring pre stores energy, and the operation (manual or electric) mechanism releases energy through the dead point, and the spring releases energy, so that the contact is closed or broken. So the switching speed is determined by the characteristics of the operator itself and has nothing to do with the operator's fast and slow operation.

K type operating mechanism or A type operating mechanism can be used separately if the 2. phase is taken with a fuse
