In addition to the supplementary information listed in the table, according to GB5959.41992 Section 2, GB595.4 Safety of electric heating equipment Part 4: General requirements for electrical protection GR5S.4133?1IF6F3.1975 G1821 Gas exchange equipment for gas shock protection G521.133.cE503644:1521EC6C364447 Electrical safety protection equipment for buildings Part 4 17, installation of protection equipment for pure sound 3 fixed support In addition to the following substitutions and additions according to (1595!4-152 Section 3 3.2 Glass-melting furnace (through) glass-meltingturnace adopts direct and (or indirect electrical heating methods) its power through the two of the sub 3.2.101 pot furnace pot The furnace adopts indirect heating type in the process of heating the material into small pieces and puts them into the furnace. 3. 2. 102 fillingmachine puts the material into the furnace after the material is heated. The exlretion machine takes out the liquid from the molten steel and transfers it to the machine side of the next workshop. 3.2. 104 Extractimnpnint A parallel port of the glass melting furnace. Through this parallel port, the finished product can be taken out and transferred to the lower part by the working tool or the material taking hole. Note: For weak protection, raw materials are prohibited! Incoming materials or taking out rotten materials, 1 GB5959.41—2004/[HC60519-21:199E3.2.105 Personal safety electrical The electrode is used as an equal return reverse electrode in the glass culture tank. 4 Classification of voltage of electric heating device According to GB99.41992 Section 4 5 Classification of electric heating device according to frequency According to GH.412 Section 6 6 General requirements According to G5959.11992 Chapter 6 7 The ground as the first part of the effective circuit shall be in accordance with Chapter 7 of GB5959.41SS2. 8 Nameplate, marking and circuit diagram shall be in accordance with Section 3 of GB59541952 9 Overcurrent protection Safety 59394-1902 Section 9. 10 Isolation and disconnection wwW.bzxz.Net According to Section 1 of B.4-1992. 11 Internal connection with the power grid |tt||board GB4992 Section 11 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. Tip: This standard content only shows part of the intercepted content of the complete standard.
