Ksg 6-10kv 50-1600kVA 400-1200V Common Type Mine Dry-Type Transformer

Product DescriptionKSG series mine dry-type transformers are suitable for central substations, underground yards, general air inlets and main air inlets in coal mines. Metal and non-metal mines that have gas but no explosion hazard are used to supply power to various equipment in mines and underground mines, and are also used to power public railway tunnels.KSG series mining dry-type transformers are dry-type transformers with IP20 protection grade shell and can be used in combination with high and low voltage switches. The general dry-type transformer for mining is composed of a separate dry-type transformer, shell and cable. It is used as underground power supply and substation equipment, which is the dry-type transformer for mining. The dry-type transformer for general-purpose mobile substations for mining does not have When equipped with high and low voltage switches, the middle case part is equipped with the transformer core, that is, the winding part and the iron core part.Model Description Technical parameters and structure dimensionsProduct features and scope of useproduct structure:The general dry-type transformer for mining is composed of a separate dry-type transformer, shell and cable. It is used as underground power supply and substation equipment, which is the dry-type transformer for mining. The dry-type transformer for general-purpose mobile substations for mining does not have When equipped with high and low voltage switches, the middle case part is equipped with the transformer core, that is, the winding part and the iron core part.The input voltage of the dry-type transformer can accommodate the line voltage from +5% to -5% of the rated voltage. If it is necessary to change the high-voltage input tap voltage, open the high-voltage junction box cover on the box after confirming that the transformer is not energized, and change the position of the connection piece on the high-voltage tap board according to Table 4. When leaving the factory, the connection pieces are always at 4-5, that is, the rated input voltage is 10000V.The dry-type transformer case is welded with steel plates, and ventilation holes are added on the side of the main body to increase the heat dissipation surface. There are four hanging plates at the lower part of the dry-type transformer box, which must be used at the same time when lifting the whole machine. The lower part of the box is provided with a sliding shoe. The lower part of the dry-type transformer box is provided with two M12 external grounding bolts with grounding symbols.The general type dry-type transformer used in mines is used as electrical equipment in the power supply system of non-coal mines. A separate feeder is used for the equipment.Product Advantages &Characteristics:1. KSG mine dry-type transformers have the advantages of safe, reliable, energy-saving, fire-proof and explosion-proof, no harmful gases, no pollution to the environment, and simple maintenance.2. Product performance indicators are superior, maintaining excellent electrical and mechanical properties during the entire service life. It is most suitable for environments with high fire protection requirements, large load fluctuations and high heat resistance levels.3. The iron core of KSG mine transformer is made of high-permeability and high-quality cold-rolled silicon steel sheet, with small joints, low loss and low noise. The coil adopts the most advanced winding technology, and heat-resistant insulating materials are used between layers and turns. The insulation grades are F and H heat-resistant grades, which can be operated for a long time under a 180° environment.4. The coil is vacuum dipped with imported paint, and the dipping paint completely penetrates the deep layer of the coil. 160ºC~170ºC drying and curing, high mechanical strength. The body is vacuum-dried by variable pressure method, and the surface of the body is covered with a layer of anti-moisture paint, which has good insulation properties.normal operating conditions:Dry-type transformers should work normally under the following conditions:a) Altitude: no more than 1000m;b) Ambient temperature: -20ºC~+40ºCc) The relative humidity of the air does not exceed 95% (at +25°C);d) in a gas or vapor environment that does not damage the insulation;e) For use in explosive atmospheres without methane dust.Product installation and useInstallation and commissioning:Carry out a comprehensive inspection of the product and necessary electrical tests before installation1. Install mine dry-type transformer(1) Installation site1.1 The transformer should be installed near the load center.1.2 The protection level of the transformer room should meet the requirements of IP20 protection level. Corrosive gases and dust particles should be prevented from attacking the transformer.(2) Installation basis2.1 The foundation of the transformer must be able to withstand the full mass of the transformer.2.2 The foundation of the transformer shall meet t
