Štandardné 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. Toto zahŕňa:
1. Vykonávanie hydroizolácií, izolácia proti vlhkosti, antikorózne, a tepelne odolné opatrenia, na základe relevantnej odbornej literatúry. This involves enhancing the design with vodeodolný and rainproof features.
2. Addressing potential spark hazards at junctions: Electrical equipment, statickej elektriny, 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 konštrukcia odolná voči výbuchu typu, stupňa, 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. Teda, awareness among the installation staff is as crucial as the maintenance carried out at the production site.
Štandardné 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 rozvodná skriňa odolná voči výbuchu.
Štandardné 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.
Štandardné 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 pozitívny tlak cabinet’s doors should maintain their sealing ability for normal operation.
Štandardné 5: Grounding Considerations During Installation
Ensure that the uzemnenie wire is connected to a dedicated grounding screw during installation.
V súhrne, 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.
