What is the difference between ks11 and KSJ9 transformer

Hello! I am a sales representative of a power transformer manufacturer!

Main products: oil-immersed power transformer (10kV class S9 S9-M BS9-M) 10kV class S11-M (35kV class S9).

10kV class SH15-M amorphous alloy oil-immersed transformer) 10kV class unencapsulated coil dry-type transformer).

10kV epoxy cast dry-type transformer (SG series, SCB series), 35kV class and below:

Oil-immersed self-cooling, strong oil-cooled electric furnace transformer.

Rectifier transformer.

Single-phase transformers.

Mining transformers.

Single-phase three-phase reactor.

Grounding transformer.

Arc suppression coils. Below 10kV level.

Box-type substation, distribution cabinet, high-voltage ring main unit, etc.

Oil-immersed metering box Dry metering box (combined transformer).

High and low voltage transformers.

Machine tool transformers BK SG DG series.

High-frequency transformers, reactors, energized reactors, etc.

All products are produced by regular manufacturers!

Place of origin: Sichuan, Chengdu.

Our company has accumulated more than 30 years of technical strength and development and improvement, and is committed to the design and manufacture of energy-saving, environmentally friendly, safe and reliable power products.

I just know that the no-load loss of the KS11 is 20% to 30% smaller than that of the KS9 type, as for that J I haven't seen it.

The transformer is the same, the difference is only in the form of an oil pillow.

1。Open oil pillow: The oil pillow is directly connected to the atmosphere through the connecting pipe and the dehydrating breather, so that the oil in the oil pillow is in contact with the air, the oil is easy to be oxidized, and the moisture in the air is also easy to enter the oil of the transformer, so it is generally only used in the transformer of low voltage level, such as 10kV and some 35kV transformers.

2。Diaphragm oil pillow; The oil pillow is divided into two parts, with an arc-shaped adhesive film sandwiched in the middle to separate the oil from the atmosphere, so that the moisture in the atmosphere cannot enter the transformer oil, and the oil is not easy to age. It uses the arc shape of the adhesive film to absorb the expansion of oil when the temperature of the transformer rises, and is mostly used in transformers of 35kV and above.

3.Capsule oil pillow: the same function as the diaphragm oil pillow, it puts a capsule on the oil surface of the oil pillow to separate the oil from the atmosphere, so that the part of the atmosphere can not enter the transformer oil, and the oil is not easy to age.

The capsule communicates with the atmosphere through the connecting pipe and the dehydrating breather, and absorbs the expansion of the oil when the transformer temperature rises through the shrinkage of the capsule, which is mostly used in transformers of 35kV and above.

Sealed 11 series three-phase oil-immersed mining transformer (copper wire). (According to the "JB T-3837 Transformer Product Model Preparation Method").

S - "three" phase.

Z - has "loaded" voltage regulation.

Type 9-9 loss.

g - "Isolation".

m - Full "airtight" seal.

Three-phase with on-load voltage regulation and decomposition switch.

The main reason is that S11 is more energy-saving, more reasonable, copper loss, iron loss is smaller, and now the transformer is estimated to be S11, but S11** is expensive.

Mining transformers have explosion-proof and non-explosion-proof, depending on your use environment, there are KS9 and KS11, 11 is more energy-efficient than 9, I don't know which model you want, there is no way to give you parameters.

Yes, for the sake of safety, it must be separated into a separate chamber, and the foundation should also be used for accident oil pool, and the oil can be used during maintenance, but if you can arrange enough in the maintenance time, you can also not do it, put the transformer pressure higher, and directly transport it away in barrels, and the accident oil pool is difficult to use once in ten years, depending on your specific situation.

If the transformer is not ordered, it will be replaced with a dry-type transformer. The oil-immersed transformer is not up to standard in the downhole, so there is no foundation accident oil pool, and it is not used to separate it into a chamber, but it can be separated into a fire fence in the middle of the hole.

But it doesn't mean that it's broken, it's just that the insulation is lowered, and the transformer is a very evil thing, and sometimes 2 insulations can be used to send electricity, and it's good to use it, and you still use the meter to measure the lower resistance.

The models are different, and the capacity is the same: 315kva, 400kva, 500kva, and 630kva

capacity of the transformer. The models are S9 S11 oil-immersed transformer, dry-type transformer, KS11 mining transformer, KBSG mining explosion-proof transformer, ZS11 rectifier transformer.

The GB standard specifies that the capacity is KVA
