Problems solved by technology

[0002] At present, the planned maintenance system adopted by most of the power equipment in the power system has serious defects, such as frequent temporary maintenance, insufficient or excessive maintenance, blind maintenance, etc., which makes countries around the world spend a lot of money on equipment maintenance every year
For a long time, my country's power system has implemented a regular maintenance system for power equipment, that is, equipment is tested and maintained according to the planned time period, so there are disadvantages of overhaul and insufficient maintenance
Due to a fault in the power system, it often causes a large-scale power outage
However, the existing power equipment has the problem of relatively high failure rate.

Embodiment Construction

[0014] A method for manufacturing a 10kV dry-type transformer, comprising the following steps:

[0015] The iron core is made of cold-rolled grain-oriented silicon steel sheet, and an anti-corrosion protective layer is applied to the outer layer of the iron core;

[0016] Combine the manufactured winding with the core, and wrap the outer surface of the winding with high-voltage winding resin;

[0017] Then put the combined winding and core into the combined transformer shell,

[0018] Set the thermometer and control box on the transformer.

[0019] Preferably, the winding is made of oxygen-free copper wire or copper foil.

[0020] Preferably, the transformer is installed with feet, and positioning holes for installation are arranged on the feet.

[0021] An air-cooling device is also arranged on the transformer, wherein the air-cooling device is connected with the control box through wires, and the fan in the air-cooling device adopts a low-noise axial flow fan.

Abstract

The invention discloses a manufacturing method for a 10-kV dry-type transformer. The manufacturing method comprises the following steps that an iron core is made of cold-rolled grain-oriented silicon steel sheets, and an outer layer of the iron core is coated with an anti-corrosive protective layer; a manufactured winding and the manufactured iron core are combined together, and the outer surface of the winding is wrapped by high-voltage winding resin; the combined winding and iron core are put into a combined type transformer shell, and a thermometer and a control box are arranged on a transformer. Accordingly, the advantage of decreasing the equipment failure rate is achieved.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a method for manufacturing a 10kV dry-type transformer. Background technique [0002] At present, the planned maintenance system adopted by most of the power equipment in the power system has serious defects, such as frequent temporary maintenance, insufficient or excessive maintenance, blind maintenance, etc., which makes countries around the world spend a lot of money on equipment maintenance every year. For a long time, my country's power system has implemented a regular maintenance system for power equipment, that is, equipment is tested and maintained according to the planned time period, so there are disadvantages of over-maintenance and under-maintenance. A fault in the power system often causes a large-scale power outage. However, existing power equipment has a relatively high failure rate. Contents of the invention [0003] The object of the present invention is to propos...
