एलईडी विस्फोट-प्रूफ लाइटहरू स्थापना गर्नको लागि सर्किट कसरी छनौट गर्ने

एलईडी विस्फोट-प्रूफ बत्तीहरूको सुरक्षित र प्रभावकारी स्थापना सुनिश्चित गर्न, it’s crucial to consider the following points while selecting the electrical wiring:

विस्फोट-प्रूफ बत्तीहरूको स्थापना

1. स्थान चयन:

सर्किट अपेक्षाकृत कम विस्फोट जोखिम वा इग्निशन स्रोतहरूबाट टाढा क्षेत्रहरूमा अवस्थित हुनुपर्छ.

2. तारिङ विधि:

विस्फोटक वातावरणमा, the primary wiring methods include using explosion-proof steel conduits and cable wiring.

3. अलगाव र सील:

For circuits and protective conduits, केबलहरू, or steel pipes passing through walls or slabs separating different explosion hazard levels, non-combustible materials should be used for tight sealing.

4. Choice of Conductor Material:

For areas categorized under explosion hazard level 1, copper wires or cables should be used. In scenarios with severe vibrations, multi-stranded copper core cables or wires are recommended. Aluminum core power cables are not suitable for underground coal mines.

In explosion hazard level 2 वातावरण, power lines should be made of aluminum wires or cables with a cross-sectional area greater than 4mm², and lighting circuits should have a cross-sectional area of 2.5mm², placed above the aluminum core wires or cables.

5. Allowable Current Carrying Capacity:

क्षेत्रहरु को लागी 1 र 2, the chosen cross-sections of insulated wires and cables should have a conductive capacity not less than 1.25 times the rated current of the fuse and the setting current of the long-time overcurrent release of the circuit breaker.

The permissible current capacity for branch circuits of low-voltage squirrel cage asynchronous motors should not be less than 1.25 times the rated current of the motor.

6. Electrical Circuit Connections:

1. The intermediate connections of circuits in zones 1 र 2 must be near explosion-proof junction or connection boxes compatible with the hazardous environment. क्षेत्र 1 should use flameproof junction boxes, while zone 2 can utilize बढेको सुरक्षा type junction boxes.

2. If aluminum core cables or wires are selected for zone 2 सर्किटहरू, the connections must be reliable to facilitate easy installation and maintenance by users.

This guidance aims to assist in selecting the appropriate wiring for installing LED explosion-proof lights, सुरक्षा र कार्यक्षमता दुवै सुनिश्चित गर्दै.
