Electrical installation points <br> <br> explosive atmospheres explosion-proof cameras, in principle, according to GB50058-92 "explosion and fire hazard Electric Power Design", GB50257-96 "installation of electrical installations explosion and fire hazard electrical equipment “Construction and Acceptance Specificationsâ€, CD90B-85 “General Drawing of Wiring and Electrical Installation of Explosive Hazardous Locationsâ€, IEC79-14, 1996e Electrical Equipment for Explosive Gas Environments Part 14: Electrical Installation of Hazardous Locations (Excluding Coal Mine) . However, electrical installations in hazardous areas should first meet the requirements of the general electrical installation specification. That is to say, electrical installations in hazardous locations must meet the special requirements in the above standards after achieving the general electrical installation specification requirements. For example: General electrical installation, black plastic cloth is a widely used insulation packing material, but is not allowed in dangerous places. Where it is necessary to perform insulation dressing, it is required to use self-adhesive tape dressing. Electrical installations in hazardous areas should be based on safety. Use of electrical products should be minimized in hazardous locations. The installation location must also avoid the sources of release and avoid the effects of heat, water, and vibration of the process piping.
Use explosion-proof camera maintenance points <br> <br> in order to prevent damage to the camera explosion-proof structure and performance, professional equipment inspection and maintenance should be performed by trained technical explosion-proof electrical end-user professional and technical personnel responsible.
1. The entrance of the explosion-proof camera must be sealed with rubber seals. It is forbidden to replace it with other methods such as filling sealant and asbestos rope; it is forbidden to fill any substance in the cavity. Explosion-proof performance is forbidden; For the convenience of connection, the sealing ring at the inlet and its matching pressing nut are forbidden to be discarded; multiple single-stranded wires are forbidden to merge and enter the inlet port through the single-hole elastic sealing ring. The oil on the rubber seal should be scrubbed to avoid aging deterioration.
Second, it is prohibited to accidentally modify the explosion-proof camera's structure, components and equipment inside the line. The fastening bolts shall not be interchanged or missing, and the elastic gaskets and metal gaskets of the extra inlet and outlet ports must be kept sealed at the factory, and the compression nut should be tightened to seal the inlet.
3. It is forbidden to carry live electrical equipment and lines in explosion hazardous locations, and to prohibit transmission of electricity or power outages when the time comes. And a warning sign “Someone working, no closing†should be hung on the offsite. During inspection and maintenance, if the explosion-proof camera is disassembled into a safe area, the equipment power cable end of the site shall be properly handled and shall not be powered on.
Fourth, daily operation and maintenance inspections, should try to avoid opening the explosion-proof camera shell, must first open the power should be cut off. If the explosion-proof enclosure is opened, the explosion-proof surface shall be properly protected and shall not be damaged. During the inspection, the explosion-proof surface shall be placed upwards, and shall not be in direct contact with the ground. After the scene is cleaned, it shall be coated with a phosphatizing paste or 204 anti-rust oil.
V. All explosion-proof cameras shall establish equipment files, install, test, operate, and repair equipment, and decompress and decompose the equipment until it is decommissioned. Various technical data of different periods should be collected, archived, and numbered one by one on the device.
