Of course, box-type transformers are not separate transformer products. They are equivalent to a small substation, which belongs to the power distribution center of the terminal, which is connected to the electricity demand of many households or other terminals. On formal occasions, it is a box-type substation.

Box Transformer Specifications
The size of the box transformer is 315, 400, 500, 630, and so on. The box-type substation is mainly composed of electrical units such as a multi-circuit high-voltage switch system, armored busbar, substation integrated automation system, communication, metering, capacitance compensation, and DC power supply. It is installed in a moisture-proof, rust-proof, dust-proof, Rodent-proof, fire-proof, anti-theft, heat insulation, fully enclosed, movable steel structure box, mechatronics, and fully enclosed operation.

Safety distance of box transformer
The safe distance of the box-type substation is: 500kv, 5 meters; 220kv, 3 meters; 110kv, 1.5 meters; 35kv, 1 meter; 10kv, 0.7 meters. The Chinese box-type transformer manufacturer tells you that as long as this distance is guaranteed, you will not be electrocuted. Secondly, with regard to electromagnetic wave radiation, power transmission and distribution are all at a low frequency of 50HZ, and the release of low-frequency electromagnetic waves is also high-frequency electromagnetic waves that really cause harm to the human body. Like the water ripples caused by stones, electromagnetic waves will gradually weaken with the propagation distance. The outdoor box-type substation itself emits low-frequency electromagnetic waves, which tend to weaken with distance, and naturally cause less damage.

The composition of the box transformer
It is composed of a transformer, high-voltage voltage control equipment, and low-voltage control equipment. The main components of the transformer are the iron core (body) and the windings. The core is the magnetic circuit of the transformer, and the winding is the circuit of the transformer. The two constitute the core of the transformer, that is, the electromagnetic part. In addition to the electromagnetic part, there are also components such as a fuel tank/cooling device/insulation sleeve/voltage regulator, and protection device.

800kva box type transformer size
The size is 1750*985*1650. 800kva box-type transformers are widely used in local lighting, high-rise buildings, airports, terminal CNC machinery, equipment, etc. Simply speaking, dry-type transformers refer to transformers whose iron cores and windings are not immersed in insulating oil.

Working principle of box transformer
The Chinese box-type transformer manufacturer tells you that the basic principle is to carry out reasonable assembly in the prescribed order through the pressure start system, armored wire, substation automatic system, DC system, and corresponding technical equipment, and install all components to a specific It is a specific transformer formed in a completely sealed tempered box structure such as waterproof, dustproof and rodent proof.

Integrated box transformer
The standardized design scheme of 10kv high and low voltage prefabricated substations gives three types of European box transformers, namely: standard type, compact type, and alternative type. The molding of the miniaturized box transformer is based on the third scheme in the alternative design scheme. It has a finished glyph layout as a whole, which is an "integrated structure".

Combined box transformer
This a warm reminder from Chinese box-type transformer manufacturers that the structure of box-type substations is relatively compact, and each box constitutes an independent system, which makes the combination method flexible and changeable. The user can freely combine some modes according to the actual situation to meet the requirements of safe operation. need.
