Shenhai, odporen na eksplozije
Mnogi uporabniki kupijo protieksplozijsko varne zasilne luči, vendar niso prepričani o postopku ožičenja. Za obravnavo tega vprašanja, Ta članek sem napisal v upanju, da bom pomagal.
Metode ožičenja:
Kot običajne svetilke, zasilne luči imajo običajno tri žice, vsak v različnih barvah:
a. Vijolična (ali rdeče): Žica pod napetostjo;
b. Črna: Neutral wire;
c. Modra: Switch wire.
Before wiring, we must consider whether we will use the light only in emergencies or also during regular conditions.
1. For emergency use only: Simply connect the live and neutral wires.
2. For regular use, like the wiring method used in gas station explosion-proof lights: Connect the switch wire and the live wire to the same live terminal, fit a switch on the switch wire, and connect the neutral wire as usual. Note that there is still only one neutral wire coming in.
Na splošno, our gas station’s explosion-proof emergency lights have three wires, two of which are stripped, and one that is not. If you wish to cut the power, connect the two stripped wires. If you want the light to be on continuously, regardless of power availability, connect all three wires, where one is the switch wire, essentially a live wire, resulting in two live wires and one neutral wire.
Pomembni premisleki:
1. Correctly understand the characteristics of each wiring method to avoid improper connections that fail to function as intended.
2. If the explosion-proof emergency lighting is part of the normal lighting system, a three-wire control method should be used.
3. For multi-storey public buildings without a fire control center, local switch control (individual or group control) or three-wire centralized control can be used for each explosion-proof emergency light.
4. In projects with a fire control center, to meet the requirements during a fire, the emergency lighting on the fire floor and related floors can be activated from the control center.
By adhering to these guidelines and understanding the wiring methods, users can ensure their explosion-proof emergency lights function effectively and safely.
