Explosion -proof electric gourd is a newly developed explosion -proof lifting equipment developed in my country. The components of the equipment are used for special sparkless information, and the performance is good and reliable. Explosion -proof electric gourd electrical requirements are as follows:
1. Electric equipment for explosive gas environment shall comply with the provisions of GB3836.1, GB3836.2, GB3836.3, GB3836.4. The electrical equipment for combustible dust dust environment shall comply with GB12476.1 regulations.2. In the explosive gas environment, all electrical equipment should be used for explosion -proof electrical equipment, and the motor and control box (excluding the wiring box) should be explored.
3. When the combustible dust environment, the electric motor and control box used by explosion -proof electric gourds are recommended to be designed and produced according to the dust dense shell. Other electrical devices, such as the button device, a lifting limiter, a weighing limiter, operating itinerary switch, and operating itinerary and switch The wiring box can be designed according to dust -proof or dust -density.
4. The introduction of the power supply of explosion -proof gourds should be conducted with soft cables. The continuous between electrical equipment should be used. Multi -share cables should be used for rubber sleeve cores, and a core ground wire should be used. There is no connector in the middle of the cable, and explosion -proof wiring boxes can be set if necessary.
5. The introduction device of each explosion-proof electrical equipment shall comply with 10.3.2 in GB3836.15-2000.
6. In explosion -proof electrical shells, warning signs should be provided. In the explosive gas environment, a warning plate with "strictly prohibited power opening" should be provided. When the flammable dust environment, there should be a "strictly prohibited turn -on opening" warning plate.
7. The installation of explosion -proof gourd electrical equipment for explosive gas environment shall comply with the relevant provisions of GB3836.15. The installation of explosion -proof gourd electrical equipment for flammable dust environment shall comply with the relevant provisions of GB12476.2.
