LMZC Inflatable cabinet CT

What is an inflatable cabinet?
inflatable cabinet is high voltage components such as busbar disconnecting switch transformer seal in filled with low pressure (0.1 ~ 0.5 mpa) sf6 inside the shell of air or other gas cabinet brings many advantages, its biggest advantage is not affected by the external environment, such as lon unclean animals and chemical another advantage because of the use of compressed gas insulated (e.g., sf6 n, or air), help to develop in the direction of miniaturization of aeration tank has a good performance without oil switch, especially the vacuum switch is a maintenance free or less maintenance, greatly reducing the workload of maintenance and overhaulFrom the world's point of view, inflatable cabinets have developed rapidly and their usage has increased dramatically. Take Germany as an example. A few years ago, an investigation was made on medium-voltage switchgear used in industrial power grid.using made investigation of medium voltage switchgear, the aeration tank in 12 kv 5% in 24 kv 9% 19% in 36 kv but according to the latest report, 2003, aeration tank has accounted for 50 of the new equipment ring network cabinet have accounted for about 75%.

LZCK series instrument current transformers applicable for AC power system 35kV and measurement of current of power supply equipment below 10KV, and microcomputer protection. This type of current transformer employs imported silicon steel which with high permeability as magnetic material, have the characteristics of Small magnetic circuit loss and can be cut, its semicircular core and secondary windings employ high quality epoxy resin vacuum, casting in plastic-case which is flame retardance anti-moisture, stable performance, no maintenance.
