1. The electrical components of electrical components should meet the requirements of the relevant national standards, be able to withstand the working temperature of the lamp cavity for a long time, provide electrical parameters that are compatible with the light source, and be in conformity with the requirements of various explosion-proof lamps.
2. The dimension of the wiring chamber wiring chamber must be designed to meet the specific explosion-proof performance requirements. It should also be easy to connect and leave a space suitable for the bending radius of the wire. After the correct wiring, the clearance and creepage distance comply with the relevant standards, and the inner wall of the wiring chamber and the normal work The inner wall of the metal shell that may generate sparks must be painted with arc paint.
3. Connections and terminals
1 The connecting piece, insulation bushing and terminal shall have sufficient mechanical strength to prevent damage during installation. The wiring should be solid and reliable, prevent loosening, and can not be loosened due to vibration, heat, thermal expansion and contraction of the conductor and insulation.
2 The power connector should be designed so that when multiple stranded conductors are connected, if the cable head comes out of the terminal, it will not touch the surrounding metal parts.
3 Terminals should take measures to prevent loosening to prevent the wire at the root of the terminal from being twisted. It is not allowed to press the connecting wire directly with the screw head, which will easily damage the wire head.
Explosion-proof light fire emergency lighting is an important part of building fire protection components, including fire emergency lighting and fire emergency lights, also known as fire emergency lighting and evacuation signs. Its main role is to provide safe protection for the safety evacuation of personnel, the persistence of work at special positions, and firefighting and rescue operations in the event that the normal lighting system can no longer provide lighting. The most basic requirement is that the people in the building are in any public places. The position of the safety exit and the prescribed evacuation route can be easily identified by using a certain illuminance. A large number of fire cases show that due to unreasonable evacuation of safety evacuation facilities or poor evacuation of public buildings, personnel cannot correctly find or identify the location of safety exits during a fire, which is one of the major causes of group-related casualties and fire accidents. Therefore, whether fire emergency lighting can play its due role in fire should arouse our great attention. The author combines many years of practical work, according to the "architectural design fire protection code" (GB50016-2006) (hereinafter referred to as "construction regulations") the relevant provisions of the fire emergency lighting in the construction of the application to talk about their own views. First, the setting range of fire emergency lighting . Article 11.3.1 of "Building Regulations" stipulates that fire emergency lighting fixtures shall be installed in the following areas of residential buildings, workshops, and Class C warehouses other than residential buildings: 1. Closed stairwells, smoking stairwells and their front rooms, and fire protection Elevator (Explosion-proof lights)
