Technical Description

1. Scope of application

KSG-series mine explosion-proof dry-type transformers (hereinafter simply referred to as explosion-proof transformers) are suitable for underground mines where there are methane and coal dust explosion hazards. The product has high mechanical strength, strong resistance to humidity, salt spray and dust, and is more suitable for operation in heavily polluted environments; explosion-proof transformers comply with GB3836.1-83 "General requirements for explosion-proof electrical equipment for explosive environments" GB3836.2-83 "Explosive environments Explosion-proof electrical equipment Explosion-proof electrical equipment "d"" and other relevant standard design inspections.

2. Product features:

1. It is made of imported high-flux silicon steel sheet to ensure stable product performance and low loss;

2. The primary winding and the secondary winding are completely electrically isolated, which can effectively remove the third harmonic and suppress various interferences;

3. The coil of the product adopts red copper wire winding vacuum pressure dipping paint, curing and drying at high temperature, the paint film is bright and uniform without cracking;

4. The product is environmentally friendly, energy-saving, and has the characteristics of flame-retardant, flame-retardant, non-toxic, self-extinguishing, and fireproof;

5. This series of products has low noise, has overcurrent and overload protection, is suitable for a wide range of loads, can withstand instantaneous overload, and can work continuously for a long time.

Three, structural characteristics

 The box shell of the KSG type mine explosion-proof transformer is made of steel plate welding. The box shell can withstand the hydraulic test of 8 atmospheric pressures; the contact surface between the box cover and the box edge meets the explosion-proof requirements; the box cover is made of steel plate It is made with two cable outlet sleeves on it. A rubber gasket is placed on the inner surface of the outlet sleeve. The cable passes through the rubber gasket. After tightening the coil, the rubber gasket can be used to compress the cable to ensure sealing. The outer diameter of the selected cable must be The rubber gaskets are tightly matched to ensure that the cable can be compressed and completely sealed to ensure the tightness protection performance;

The size and weight of KSG-100KVA 0.69KV/0.38KV are in accordance with the actual factory standard. The basic parameters are as follows:

1 Input rated voltage: three-phase AC690V; output rated voltage AC380V; working frequency: 50Hz-60Hz

2 Efficiency: ≥95% 3 Temperature rise: <60 4 Waveform distortion: <0.1% 6 High voltage test: 2500V, no breakdown in 1 minute
