NsawamHow much is 315 box transformerWhat are the price and performance advantages

Difference between dry-type transformer and oil immersed transformer:

It includes the performance and main uses of insulating layer materials, various insulating layer parts, component manufacturing processes and quality standards; Performance and main uses of various wires, coil inductance process of various ways of electromagnetic coil, solution process and quality standard, overall suit process and quality standard of electromagnetic coil; Main performance parameters of ferrite core, cutting process of iron chip core stacking process and quality standard, production process and quality standard of electromagnetic shielding.

Nsawam.With Vietnam and Malaysia, China's first UHV transmission experimental demonstration project, China Transformer Corporation has entered a breakthrough in the development trend. The commodity voltage grade and volume rank first in the world,NsawamMain components of oil immersed transformer, occupying the main technical position of the industry development trend. In addition, it has promoted the continuous improvement and perfection of the technology of low-voltage transformers.

The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core which is stacked at the 45 degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, and has sound insulation and noise reduction.

When checking the hook core, the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken, turn on the photo flash when it's light, and it's short when it's heavy. Therefore please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance, experts can inspect special tools, parts, insulation, generally from half a year to once a year;

Generally speaking, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer, disconnect the switching power supply on each side, quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited, the generator set must be disassembled first.

Professional is king.In the electric field of the winding to the yoke, there must be a strong line breaking component, so that sliding flash charge and discharge may occur at a lower current. In order to better solve this disadvantage, the appearance of the insulating parts between the winding and the iron yoke should be the same as that of the medium horizontal plane of the winding to the iron yoke insulation as far as possible, so as to reduce the electric field component intersecting with the insulating parts.

The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, resulting in heat,NsawamHow much is a 400 KVA box transformer, temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.

(5) the installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side, it shall be installed between the disconnector and low-voltage composite insulator,NsawamParameters of scb11 dry type transformer, or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side, it shall be installed on both sides of the low-voltage composite insulator, and the insulated cable jumper shall be connected to the insulated cable on both sides of the circuit breaker.

Test conclusion.The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, resulting in heat, temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.

Oil sample inspection & mdash; & mdash; the performance parameters such as compression resistance and residue shall be carried out every three years. The long-term overload or overload of the transformer can reduce the cycle time.

A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?

The first step of the whole wave process calculation is to calculate the basic parameters of the Internet such as inductance, capacitance and resistor. The accuracy of those basic parameters does great harm to the calculation results of the whole wave process. For the inductance calculation, the good model is the solid model of infinite transformer core column, but there are many calculation methods.

The electromagnetic coil is wound with copper power wire or foil and lifted with glass fiber. The epoxy adhesive does not need filling. The vacuum drying equipment is used for degassing and dehumidification. The overall concrete is poured with high fracture toughness, resistance to short-circuit faults, common faults and impact. The work is diligent.
