Important factors for installation: Install electrical equipment as far as possible in an area with a low degree of hazard 1. Confirm that the explosion-proof distribution box for the chemical plant to be installed complies with the design requirements (model specification, voltage rating, rated current, enclosure protection, installation method, explosion proof Marking, introduction method, wiring cable, steel pipe inlet thread, position, etc.)
2. Verify that the environmental conditions at the installation site are in accordance with the requirements of the equipment, such as the altitude, ambient temperature, relative humidity, atmospheric pollution, and corrosive gas conditions.
3. Confirm that the equipment is suitable for use in this hazardous area and familiar with the types and characteristics of flammable gases contained in the site, such as grade, group (ignition temperature), flash point, explosion limit (upper and lower limit), etc.
4. Determine the installation location. There should be enough space and access around the equipment.
Chemical plant explosion-proof distribution box operation process 1. When the equipment is put into operation, pay close attention to the instrument display, and read the meter according to the specified time. It is necessary to conduct regular inspections to check whether the porcelain, casing, petrol equipment oil level, busbars and various electrical connectors are overheated.
2. Before the use of explosion-proof power distribution boxes in chemical plants, they must strictly comply with departmental requirements, do all the preparatory work, and wear good insulation and insulation tools.
3. The operator is required to obtain an operation certificate after passing the examination. The operator shall be familiar with the performance and structure of the machine, and shall abide by the safety and handing over system.
4. The distribution box must adhere to one-person operation and one-person guardianship system during operation, and must earnestly implement the work procedure requirements of the work ticket.
The monthly maintenance methods for explosion-proof power distribution boxes used by chemical plants are as follows:
1. The line in the stationary contact and the fixed contact should be consistent, the contacts should be in close contact, and sufficient pressure must be ensured.
2. The column grounding device is good 3. Check the performance and fixing of all electrical components and accessories.
4. Check the metal busbars and terminal blocks against galvanic corrosion and the deformation of the busbars after they are pressed.
5. Check and clean all the power distribution devices.
6. The operation of the operating mechanism should be flexible, and the auxiliary contacts should be properly separated.
7. Clean the inside and outside of the power distribution device.
8. Pay close attention to the display of the instrument during work and whether the various electrical connectors are overheated.
9. Check if each connection is good.
10. Inspect the porcelain bottle, casing, bus bars and various electrical connectors.
The role of explosion-proof distribution box in the industry is obvious, of course, correct and timely maintenance work is also very important, timely maintenance of the explosion-proof distribution box can ensure the stability of its explosion-proof performance. ensure safety!
