How to choose an explosion-proof LED illuminator

Stand sa from the type of disputed degree to the danger from the explosion. In tyah, as well as in rooms with a normal environment, there is artifical and artistic clarification.

For yes, it will create safe conditions for working for electrically interfering in the industry, all using explosion-proof lighting devices. Explosion-proof LED body illuminators are the only one you can see from the light source in the basin category.

Vidov

There are three types of explosion protection for electrical equipment:

• Nivo 2 - Explosion-proof properties are valid by itself during normal operation;
• field 1-explosion protection parameters and ensure operation of the equipment during normal operation and in the event of an emergency, causing from damage, with an exception to the means, insuffi- cient explosion safety;
• nivo 0 - equipped with a tosi type ima is equipped with a degree of explosion safety, something that has been achieved through the use of special means for protection against explosion.

For your information! Nothing for explosion protection on lighting equipment is displayed on the top of the bad marking and it is indicated with the first number in the designation.

Features

Distinguish between the explosion-proof lighting body and conventional analysis following indicators:

1. The case is made from irritable materials, which can and will cost mechanical wear on the outside and significantly change the temperature in the surrounding environment.
2. Glass, used in illuminating bodies, is not a heat-resistant material.
3. All the structural elements are securely and tightly connected, somehow oscillating the density on the outside space on the lighting body.
4. Electrical conductors, put in lamps from tosi type, are supposed to be special, except for the possibility of explosion in the case of a short connection.

Girth per application

Explosion protection lighting devices are used in potentially hazardous industries and indoors, where there is a risk from fire and explosive substances. Industry abstracts include:

• enterprises from oil and gas industry and oil refinery industry;
• enterprises for having finished off the minerals for mined the method for perverting to work;
• premises for electric power plants and energy supply in the industry of the enterprise, which is responsible for tyahnoto energy supply (tabla, ASU, etc.);
• petrol stations and petrol stations and complexes;
• production workshops at metallurgical, chemical and cellulose-charter enterprises;
• enterprises specializing in wood processing and production on wood materials;
• Zone for temporary work

Categories and types of hazardous areas and materials

In our country, hazardous areas are classified in accordance with GOST 31610.10-2012 / IEC 60079-10: 2002 "Electrical equipment for explosive gas atmospheres. Part 10. Classification for dangerous zones.

In accordance with the Tosi document, danger zones are divided into the following categories:

1. B - 1 - in rooms from tosi type, burning gas and igniting flows (FL) can even form, when mixed with air, explosive mixtures during normal operation of the equipment.
2. B - 1a - it is possible that it is formed on the explosive concentration e as a result of an emergency situation.
3. B-1b - zone from tosi type sa similar to class B-1a, with the only difference that you burn gas in tyah and the temple is full of borders on the trap.
4. V-1d - explosive spaces and areas located outdoors in the vicinity of the installation and equipment, working with ignited gases and ignited flows.
5. B - 2 - in rooms, which can be turned into a suspended state by using substances and materials, in some way there is a possibility of the formation of an explosive mixture with air during normal use.
6. B-2a-similar to class B-2, but in case of haste.

species and species

The explosion protection of LED body lighting is produced by manufacturers from different types, some of it depends on the conditions of use and location.

Use the view on the VZG to illuminate the devices for the outside and the outside.This product is reflected in the technical specifications (electrical power, voltage storage, light flow), as well as in the design of the hulls, some including various options for installation (finished, top metal and building structures, etc.).

For your information! For external illumination in hazardous areas, project a spotlight with LED light source into the light, directing it to an explosion-proof housing, which is very popular among consumers.

Preferences for explosion-proof lighting bodies

Preference for explosion protection of LED body lighting in comparison with conventional lighting sources includes the following indicators:

1. Little by little electricity, some of which allowed and se namalali natvarvaneto on the electricity bill for the consumer.
2. The current is working on the LED source for a little bit of light, therefore, the probability of a breakdown in isolation and a little spark.
3. Opportunity for work at low voltage, adjusting the safety of the device.
4. Long exploitation belly.
5. Quality indicators for radiance (uniformity, ripple on ripple).
6. Diversity from form and specification to allow you to choose the right model for a specific type of use.

Diversity from the model you allow and choose the wishes of the illuminator, both in relation to the technical characteristics, and also in terms of the appearance of the fixture back kjm sdzharzhanieto ↑

Somehow it’s written in a mountainous way, the corresponding marking is attached to all the explosion-proof design on the lighting product. And so, on the DSP-48-01 body illuminator, the Ex-marking is somehow as follows: 1 Ex db op e IIC T5, some dissuade the following characteristics:

• 1 - field for protection (in normal and emergency situations, without it, explosion protection equipment will be damaged);
• Ex - compliance with the CENELEC standard;
• db - fireproof body;
• op is - special protection, intrinsically safe electrical circuit, oily case;
• IIC - for the industry of expression;
• T5 - normal operating temperature is 100 - 135 degrees.

In order to diversify from models that differ in their design and technical characteristics, LED lamps will gradually replace analosites from conventional sources to lighting industries and enterprises with various forms of property.
