3 Phase AC Industrial Isolation Toroidal Dry Type Transformer

Specifications

Dry Type Transformer

3 Phase AC Industrial Isolation Toroidal Dry Type Transformer

1. Brief Introduction

The tansformer has flameproof feature. It can meet GB8286-2005 GB3836-2000 GB/T10228-1997 JB/T56152-94
Certification,  the standard the no-load current short-circuit impedance. As we know, underground mining is full of fire damp mixed gas, grime and explosive gas, it is very easy to on fire. Therefore, flameproof dry type transformer is popular with mining field.

2. Machine Important Information

(1). The installation is not higher than 1000m (normal)

Remark: if there are special environment, kindly contact us and tell the condition.

(1).Ambient temperature
Highest temperature: 40ºC
Maximum monthly average temperature: 30ºC
Maximum annual temperature: 20ºC
Lowest temperature: -5ºC
(2).The surrounding air relative humidity is not greater than 95% (25ºC)
(3).In the mine, with methane, dust explosion danger is well
(4).No vibration the gradient is less than 15ºC
(5). No gas or steam to corrode metal needed or destroy insulation
(6). Non-water drop sit
(7). Power supply voltage profile approximate to a sine wave
(8).The three-phase supply voltage approximate symmetrical
3. Material

100% Cu winding, steel iron.

4. Component

It is composed of three parts: high voltage distribution switch, minining explosion mobile transformation station, intelligent low-voltage protection box. 

5. Comparison

Compared with oil immersed transformer,  dry type transformer  features are 100% flame proof, no pollute (no oil leakage risk), easy to maintain (less external devices). It is suitable for mining environment.

6. Specification

Remark: Short circuit impedance about 4%. 3 Phase, AC Power, 50 HZ/ 60 HZ
