12 Protection against power outages
In addition to the following, according to G9-Chapter 1,
12.1.101 In the night screen cottonizing device, the light shear-section (rated voltage [K greater than 1000). In addition, according to K5559.4-1, the induction is connected or indirectly grounded. 12.2.191 For the connection or indirect heating and falling table, when the glass worker. Only.When wet material is put into the conductive carbon glass molten pool or when high-temperature material is being added into the glass swimming pool, measures should be taken to cut off the electric shock:
Install a personal safety contactor at the door opening, monitor the power of the electrode, when there is a support left in the installation, the melting end should be automatically cut off, if possible: the power should be cut off or other appropriate measures should be taken at this time to prevent further discharge of material. Yang: The structure of the full output and the right-hand side of the disk are in unfavorable conditions. When the molten pool in the material outlet area is still safe due to the daily sample and feeding, the private energy output and uniformity measures should be taken: such as using beneficial plates, maintaining a sufficient safety distance: to prevent the work from coming into contact with the electrode heating element when using the workpiece;
use absolute protection products (such as workpiece Zhang, Denian, Ding Nian); of course, use medicine working points:
use grounded engineers;
use low expansion films.
For indirect heating glass baking furnace (Hong Kong furnace): When the electrical measurement indicates an emergency, the automatic heating circuit GB5959.41-2004/1F:6C519-21:199812.2.192 feeder, taker and the entire valve structure of the melting tank are connected in a potential compensation manner, and the personal safety voltage should also be included in the glass tank and equipotential connection. If it is placed underground, the degree of protection is in accordance with the requirements of GB14321.1 and GB6335447. 13 Protection against thermal effects
According to GB5959.1-1492, Section 15.
14 Fire prevention and weak explosion
According to CB5U59.4199, Chapter 14.
15 Inspection of electric heating equipment. Putting into operation, use and removing the following additional external GR55%.4-1092 Chapter 15, 15.3.101 During installation and at least every 6 months, it should be checked that the power transmission parts (its potential is the same as the grounding potential) are connected to the ground potential. This includes the inspection of some important power-off systems.
