In addition, the newspaper approves medium new edition " standard of building design fire prevention " 11.2.7: Concentrated place appropriate installs the staff such as shop, theater, cinema, gymnasium system of fire alarm of leakage of electricity. Make and already approved newly in the newspaper medium " build electric fire to precaution asks and detect method " the odd cable flow that concerned article asks “ should enter a line to end installs automatic dump or call the police in power source clearly also makes protector ” .
Normative article is ” of system of fire alarm of “ leakage of electricity with the word, demonstrate the integral unit that should be net of a couplet, it is a whole system, it is the requirement of standard of corresponding GB 14287-2005, the warning apparatus of individual leakage current that sets dispersedly before or switch of traditional leakage of electricity can not be competent. In specification of expensive plan article, also emphasize these “ equipment wanting to use center of product quality supervision and inspection of electron of national fire control to detect particularly eligible product, in order to ensure quality is safe ” , be not it is thus clear that is to use switch of common leakage of electricity possible, a lot of electric design personnel often have this mistake tendency.
About the assurance of word of “ appropriate ” , the normative specification that use a word points out: Express to allow to have a choice a bit, answer to be made so above all when the condition is permitted. Visible, in principle of “ appropriate ” should consider to install above all, without special situation, without classics fire control director branch agrees, cannot choose to cancel to install casually.
Body of appliance of 2.2 exploration control selects a design issue
As a result of " civil building designs the high level fire prevention standard " it is building design standard, be not level of state of product of system of fire alarm of leakage of electricity, also be not design of special system of fire alarm of leakage of electricity, construction to check and accept a standard, accordingly, article requirement is thicker, cause at present design of system of fire alarm of leakage of electricity, construction, check and accept did not make clear article basis, carry out by oneself understanding severally, multifarious, the successful construction that certainly will affects project of system of fire alarm of leakage of electricity and move, affect its the normal play of function of electric fire monitoring.
2.2.1 " the installation of protector of movement of odd electric current and move " it is the important level that design of system of fire alarm of leakage of electricity and installation use
The author thinks, from long-term look, making design of special system of fire alarm of leakage of electricity, construction check and accept a standard is necessary, or add concerned content " fire calls the police automatically systematic design is normative " GB50116, " fire calls the police automatically systematic construction and check and accept a standard " in GB 50166, but current or quite long henceforth period of time, still will be faced with afore-mentioned “ confused ” . Current, with the country newest " the installation of protector of movement of odd electric current and move " GB13955-2005 is a standard, consult GB14287-2005 " electric fire supervisory system " concerned content is carried out, it is more feasible. Because of " civil building designs the high level fire prevention standard " the system of fire alarm of leakage of electricity that 2005 edition ask to install is “ the rest the “ in ” of voltaic movement protector is odd voltaic movement is electric ” of fire supervisory system, itself is belonged to " the installation of protector of movement of odd electric current and move " the administrative limits of GB13955-2005.
