Electrical lighting device construction and acceptance specifications torch 650259-96 Introduction Xu Xinfang Fast West Province equipment installation engineering company Xi'an 7100 electrical lighting installation is the most common construction project in the installation project, but also with people's work. Life is closely related, with the continuous development of new products and new processes, and the improvement of safety and environmental requirements, in the original national standard "Electrical Installation Engineering Construction and Acceptance Specifications" torch 8 32-82 14th electrical On the basis of the old specifications, the lighting device is revised and officially released to implement the new standard. _ Electrical lighting device construction and acceptance specifications woo 85025996 shake the new standard. This article shakes the form of the new and old norms and briefly introduces the new norms.
1Applicable to the application of this standard. The scope of application of Article 1 includes all buildings and structures. From this meaning, it can be considered that the scope of application of the new norms is more suitable for industrial and civil buildings. some. Of course, the relevant provisions of the corresponding standards must be implemented for places with special requirements.
2 New Supplements 2.1 Chapter General Provisions 2.1.1 and other newly issued standards, the new specification Article 1. 3 emphasizes that when the design is modified, it should be approved by the original design unit. Due to the ever-changing situation of the construction and installation site, the design change is also normal, but in order to ensure the continuity and integrity of the design, in the final analysis, it is to ensure the quality, shaking and use and maintenance of the building installation products.
2.1.2 Inspection of equipment and equipment after arriving at Shiwang site. The specific requirements of the old norms are not clearly examined, and at least two points are clearly defined in Article 15 of the new regulations. Technical documents should be complete in terms of model, specifications and appearance quality requirements, providing the necessary conditions for smooth construction in the future.
2.2 Chapter 2 Lamp Parts 2.2.1 The old specification allows the lamps to be directly installed on the wooden platform; the new specification Henan Province Installation Group Co., Ltd. Luoyang 471000, the combustible items should include wood, bamboo, flammable insulation materials, etc. . When the high temperature part of the surface of the luminaire is close to combustible materials, heat insulation and heat dissipation measures should be taken. This is very important to eliminate the hidden dangers of electrical fire accidents. A considerable number of electricians or power users have not paid enough attention to this.
2.2.2 New Specifications Section 2. Article 4 stipulates that the lamps shall not be installed directly above the high-Voltage and low-voltage power distribution equipment and busbars of the substation. This avoids the loss of large-scale power outages for the maintenance of such lamps; It can avoid the serious consequences of accidents caused by power distribution equipment caused by the falling of the lamps.
2.2.3 Added the requirements for the installation of Honghao. There are six lamps, brackets, transformers and their installation positions, wires and laying. See section 19 of the new specification for details.
2.3 Chapter = socket, switch, ceiling fan, wall fan installation part 2.3.1 Supplementary floor socket should have a firm and reliable protective cover requirements, see clause 3.1.1.3 of the new specification.
2.3.2 In order to differentiate the working neutral and protective neutrals in the electrical system, the new specification, section 3.1.2.2, stipulates that the grounding terminal of the end socket should not be directly connected to the neutral terminal.
2.3.3 In order to prevent electrical short-circuit or damage to electrical appliances, the new specification supplements the phase sockets of the same location, and the phase of the wiring must be completely necessary, see clause 3.1.2.4.
2.3.4 for the purpose of communication. Broken position, unified installation size, enhance the safety in use, and also for the environment is beautiful, the new specification Article 3.2.1 stipulates that the same series of products should be used in the same place.
2.3.5 The wall fan exists prematurely, but the old specification obviously ignores this point. There is no uniform specification for installing Shiwangzhong. The new specification adds the third.
4 Wall fan section, the fixed requirements of the wall fan base on the wall, vertical deviation and height from the ground are clearly defined.
2.4 Chapter 4 Lighting Distribution Box Board Part 2.4.1 In the past, wooden lighting distribution box board accounted for a large proportion. In recent years, the standard lighting distribution box recommended by the Ministry of Construction is getting more and more complete. It is stipulated that the rate of employment for special-purpose personnel should reach 100. Now there are two problems in the enterprise.
Although the special personnel have passed the prescribed training and passed the assessment to obtain the safety qualification certificate, the unit did not send the operation certificate to the person. Of course, enterprises have the company's music, but for whatever reason, unlicensed employment is absolutely not allowed. The enterprise can shake and send a copy of the certificate to the person, which facilitates the inspection of the relevant department.
Second, the validity period of the special personnel certificate has passed. According to the regulations, the operation certificate of special-purpose personnel is valid for two years and must be retrained every two years. Only after passing the examination can they be employed.
The training and collection of special personnel is an important regular work. Leaders at all levels of the enterprise must attach great importance to the implementation of training responsibilities, formulate effective measures, strengthen supervision and guidance, and make this work orderly. Effectively carry out, so that enterprises have sufficient, high-quality talents. Received 1 905- 21 good, its performance is obviously better than the wooden lighting distribution box, the model specifications fully meet the needs of Wang Cheng, regardless of fire prevention or shaking steel and other aspects, should limit the use of wooden distribution box Board, see the new specification, Article 4.
2.4.2 In order to prevent damage to the lead-level distribution box, the wire hole must be smooth and burr-free; at the same time, in order to strengthen the insulated wire through the metal panel hole, it is necessary to install the protective sleeve, see section 4. 3.
2.4.3 With the stricter requirements of electrical safety standardization, the phase five-wire power supply method not mentioned in the old specification has become increasingly popular, which requires strict distinction between the working zero line and the protective zero ground line in the lighting distribution box board. Open, the new norm 4.ification 6 has been clearly defined.
3 Other Supplementary Modifications New Specification 5025996 and Old Specification 8 282 Part 14 Comparison Table 褚 New Specification Old Specification Remarks Equipment, Equipment and Transportation and Storage 1.0.4 If there are no special requirements, it should conform to the product technical documents. It is stipulated that the installation of electric lighting devices is better than the old ones. It is strictly forbidden to use wood safer and more reliable lamps. switch. Non-charged metal parts such as sockets_Special grounding bolts with obvious signs~Apply grounding bolts to connect the safety of the standard lamps, the minimum cross-section of the civil building, the indoor lighting, the wire, the living room, the wire, the king, the 0.3, the safe operation, the installation There is a white bulb with a good ceiling. The 0.7 good foam should not be tightly attached. When the distance between the good foam and the insulating table is less than 5, the temperature between the foam and the insulating table should be taken. It is too close to the wooden table. There should be insulation measures between the good foam and the wooden table. It is better than the old one. When the steel pipe is used as a good boom, the king's steel pipe thickness is 571. The strength of the boom is soft. The technical line at both ends of Zhang 03 should be tinned to prevent gravity from loosening the thread. The lighting in the public place is not covered by the special person. The automatic energy-saving switch should meet the energy-saving requirements. The reflective lighting installed on the floor is good. 3 should take protective measures for safety and prevent damage to the luminaire. The lifting and hanging device of the large-sized lanterns should be installed. The 0.17 should be overloaded according to the weight of 125 times. The 2Q21 should be L2 times overload test and other specifications. The old specifications of the socket socket installed in the wet site are missing and installed side by side. The height of the socket switch is 3.2 or 3.2.3. The height difference should not be greater than 11 degrees. The difference should not be greater than 21. The new standard requires stricter height difference in the socket switch installed in the same room. 3. The height difference between 2/3.2.3 should not be too large. The new standard requires more specific diameter of the ceiling fan hook~~ 2.71 than the old specification.
