መደበኛ 1: Considerations for Explosion-Proof Power Distribution Boxes in Hazardous Environments
When installing explosion-proof power distribution boxes, it’s crucial to anticipate risks such as spark hazards. ይህ ያካትታል:
1. የውሃ መከላከያን በመተግበር ላይ, የእርጥበት መከላከያ, ፀረ-ዝገት, እና ሙቀትን የሚከላከሉ እርምጃዎች, በተዛማጅ ሙያዊ ሥነ-ጽሑፍ ላይ የተመሠረተ. This involves enhancing the design with ውሃ የማያሳልፍ and rainproof features.
2. Addressing potential spark hazards at junctions: Electrical equipment, የማይንቀሳቀስ ኤሌክትሪክ, lightning, and electromagnetic radiation pose risks that require personnel with professional electrical knowledge. Beyond initial product stability, ongoing maintenance is key.
3. Proper maintenance and care significantly extend the operational life of equipment. When replacing, repairing, or adjusting electrical devices, it’s essential to reassess the classification of hazardous areas or changes in electrical equipment setups, ensuring that the ፍንዳታ-ተከላካይ መዋቅር ዓይነት, ደረጃ, and temperature classifications meet new conditions.
4. Operations should be carried out by personnel trained in explosion-proof techniques.
5. Awareness Raising: Given that explosion-proof control boxes are often used in harsh environments, awareness of corrosion risks is vital. Even if the outer casing is made of aluminum alloy, its interaction with airborne chemicals can compromise its integrity. Minor installation errors can impact the equipment’s operational life. ስለዚህም, awareness among the installation staff is as crucial as the maintenance carried out at the production site.
መደበኛ 2: Wiring of Explosion-Proof Power Distribution Boxes
Wiring should be carried out in compliance with technical documents provided by manufacturers, such as electrical system diagrams, wiring diagrams, terminal diagrams, and user manuals, tailored to the specific application of the ፍንዳታ-ማሰራጫ ሳጥን.
መደበኛ 3: Ensuring Seal Integrity in Cable Wiring
The sealing integrity of the cables entering and exiting the box must be maintained. This includes utilizing explosion-proof putty for sealing, based on the tightness of the cables.
መደበኛ 4: Testing and Counting Mechanisms
After wiring and testing, the control panel, including decimal counters, registers, decoders, and digital displays, should be operational as follows:
Count pulses are directed through the main gate to the decimal counter, which tallies the pulses. After the main gate is closed, the register displays the cumulative pulse count via the decoder.
Quartz crystal oscillators produce precise and stable pulses, used as time bases after frequency division or multiplication. The explosion-proof አዎንታዊ ግፊት cabinet’s doors should maintain their sealing ability for normal operation.
መደበኛ 5: Grounding Considerations During Installation
Ensure that the መሠረተ ልማት wire is connected to a dedicated grounding screw during installation.
በማጠቃለያው, these five points are essential in the installation process of explosion-proof power distribution boxes, including the installation of surge protectors, ammeters, and voltmeters. Proper installation of explosion-proof equipment is crucial for the safe continuation of industrial operations.
