Mining cable load combustion testing machine that meets the standards

K-R386Mining cable load combustion testing machine that meets the standards

This testing machine is manufactured according to the standard MT 386-1995 "Test Method and Judgment Rules for Flame retardancy of Flame retardant Cables for Coal Mines" and is used for testingverifyMT 818-2009 "Combustion characteristics of coal mine cables under overload conditions". The outer shell of the test box is made of electrostatic baking paint, which has a beautiful color and high fastness. The experimental chamber and electrical control system have a convenient upper and lower structure for operation.

Customer's choice

4. The height of the spray gun is adjustable, and the angle of the spray gun is 90 °

5. Temperature measurement range: Imported K-type thermocouple 0-1200 ℃

6. Temperature control meter display range: 0-99.9 (with decimals), integer 0-9999 degrees

The buzzer will automatically sound an alarm when the temperature reaches.

7. Temperature control meter accuracy: Level 0.5

8. Timer range: 0~99.99 S/M can be set arbitrarily

9. Volume: 0.5m³Equipped with exhaust system

10. Weight: Approximately 500KG (3000A), Approximately 550KG (3000A), 620KG (5000A)

11. Working voltage: Combustion control box power supply AC220V/50HZ

Inverter power supply AC 380V/50HZ, 100A (3000A)/100A (4000A)/15A (5000A)

12. Total power: 20KW (3000A) 、24KW（4000A） 30KW（5000A）

13. Features: A high-performance 3000A converter ensures continuous operation for at least 20 minutes at full range for customers (while short-term operation of 2-12 minutes on the market cannot meet test requirements), with low heat generation and long service life. Using imported thermocouples from the United States, the temperature is more accurate.

Product Structure:

1. The shell of this product adopts an electrostatic baking paint shell structure

2. Spray lamp part: made of H62 brass, with a height of 205mm and an inner diameter of 9.5mm, equipped with an auxiliary automatic ignition device

3. Current generation part: mainly composed of high current transformers

Combustion chamber:Inside the box, there are two sets of metal supports for current testing and a standard methane spray lamp. The positions of the supports are shown in the following figure. The flame of the spray lamp is shown in Figure 2, and the structure of the spray lamp is shown in Figure 3,

Electric control panel:Equipped with a power source and a thermometer, it outputs a current of more than 5 times the rated current (see table below) to the current test piece, and can also measure the temperature of the wire core conductor through a thermocouple.
