ਵਿਸਫੋਟ-ਸਬੂਤ ਇਲੈਕਟ੍ਰੀਕਲ ਉਪਕਰਨ ਲਈ ਸੁਰੱਖਿਆ ਪੱਧਰ ਕੀ ਹੈ

ਉਪਕਰਨ ਸੁਰੱਖਿਆ ਪੱਧਰ (ਈ.ਪੀ.ਐੱਲ) ਸੰਭਾਵੀ ਨੁਕਸ ਅਤੇ ਰੋਕਥਾਮ ਉਪਾਵਾਂ ਦੇ ਅਧਾਰ ਤੇ ਇੱਕ ਖਾਸ ਕਿਸਮ ਦੇ ਉਪਕਰਣ ਦੀ ਵਿਸਫੋਟ-ਸਬੂਤ ਭਰੋਸੇਯੋਗਤਾ ਦਾ ਮੁਲਾਂਕਣ ਕਰਦਾ ਹੈ, ਵਿਸਫੋਟ-ਸਬੂਤ ਬਿਜਲੀ ਉਪਕਰਣਾਂ ਲਈ ਮੁੱਖ ਸੁਰੱਖਿਆ ਸੂਚਕ ਵਜੋਂ ਕੰਮ ਕਰਨਾ.

ਪੱਧਰਾਂ ਨੂੰ ਏ ਦੇ ਰੂਪ ਵਿੱਚ ਸ਼੍ਰੇਣੀਬੱਧ ਕੀਤਾ ਗਿਆ ਹੈ, ਬੀ, ਅਤੇ ਸੀ:

1. Level a ensures consistent explosion-proof safety performance under normal operations and during both anticipated and rare faults.

2. Level b guarantees the retention of explosion-proof safety performance during normal operations and foreseeable faults.

3. Level c assures the maintenance of explosion-proof safety performance in both normal operations and specific abnormal situations.

ਆਮ ਤੌਰ 'ਤੇ, an explosion-proof device is expected to meet Level 3 ਸੁਰੱਖਿਆ. In certain cases, ਹਾਲਾਂਕਿ, Levels 2 ਜਾਂ 1 may be permissible for specific explosion-proof types.

Marking methods include:

1. Based on the explosion-proof type symbol:

The combination of the ਧਮਾਕਾ-ਸਬੂਤ ਕਿਸਮ and equipment protection level symbols denotes the protection level. ਉਦਾਹਰਣ ਦੇ ਲਈ, basic safety devices are marked as ia, ਆਈ.ਬੀ, ਜਾਂ ਆਈ.ਸੀ.

2. Based on the equipment type symbol:

Merging the equipment type and protection level symbols indicates the protection level. ਉਦਾਹਰਣ ਲਈ, ਕਲਾਸ I (ਮਾਈਨਿੰਗ) equipment is marked as Ma or Mb (M representing mine); ਕਲਾਸ III (ਫੈਕਟਰੀ, ਗੈਸ) equipment is marked as Ga, ਜੀ.ਬੀ, or Ge (G for gas).

It’s crucial to understand that equipment protection levels and explosion-proof levels are distinct concepts often confused in application. The protection level indicates “ਭਰੋਸੇਯੋਗਤਾ,” while the explosion-proof level reflects “ਜਲਣਸ਼ੀਲ ਗੈਸ properties and equipment structural features.” ਉਦਾਹਰਣ ਦੇ ਲਈ, in an industrial setting with a constant hydrogen explosion risk (ਜ਼ੋਨ 0), required intrinsic safety equipment would be Level ia, Explosion-Proof Level IIC. In a less frequent ਹਾਈਡ੍ਰੋਜਨ risk setting (ਜ਼ੋਨ 1), Level ib, IIC intrinsic safety equipment would meet the needs, though Level ia, IIC equipment could also be suitable.
