IP65 factory explosion-proof power distribution box

The BXM (D) series explosion-proof power distribution box (cabinet) (hereinafter referred to as the distribution box) * complies with the requirements of GB3836.1-2010 "Explosive Environment Part 1: General Requirements for Equipment", GB3836.2-2010 "Explosive Environment Part 2: Equipment Protected by Explosion proof Enclosures", GB3836.3-2010 "Explosive Environment Part 3: Equipment Protected by Increased Safety Type" e "" or GB12476.1-2000 "Electrical Equipment for Combustible Dust Environments Part 1: Protection with Enclosures and Restricted Surface Temperature and Electrical Equipment Section 1: Technical Requirements for Electrical Equipment" standards. It is mainly suitable for hazardous areas in Zone 1, Zone 2 of explosive gas environment or Zone 20, Zone 21, and Zone 22 of combustible dust environment, as well as explosive gas or vapor environments in Class IIA, IIB, and IIC T1-T4 groups or explosive dust environments in T1-T6 groups. It is used for lighting and power circuit switching at AC 50Hz and rated voltage up to 380V.

Customized explosion-proof boxes, customized explosion-proof iron boxes, customized stainless steel explosion-proof boxes, and customized explosion-proof aluminum boxes. The purpose of type testing is to verify whether the design performance of the finalized distribution box meets the requirements of our enterprise standards. Type testing is a necessary test for the trial production of new products. Only when there are changes in product design, manufacturing process, use of raw materials, or component structure that may affect the explosion-proof performance of the distribution box, is it necessary to conduct type testing for the relevant project again. Normally produced products are tested every five years. Any type test sample shall be randomly selected from the products that have passed the factory inspection for testing. Only when both samples pass the test can the type test be considered qualified. Otherwise, it is necessary to analyze the reasons, take technical measures, or even improve the design, process, etc. before conducting the test again until the type test is qualified.

Type test items:

a) All factory inspection items;

b) Temperature rise test, temperature test;

c) Impact test on shell and transparent components;

d) Heat resistance test and cold resistance test for transparent parts;

e) Aging test of elastic sealing ring material;

f) Cable entry device clamping test;

g) Explosion proof shell pressure test;

h) Non propagating test for ignition inside the explosion-proof shell;

i) Shell protection capability test;

j) Operational performance test;

k) Maximum breaking time test for rated residual operating current and rated residual non operating current of residual current circuit breaker;

l) Test on the action characteristics of the release device;

m) Rated short-circuit breaking capacity test.

Installation, use, and maintenance:

6.1 Installation

6.1.1 Installation work must be carried out by professionals.

6.1.2 Before installation, the basic data listed on the nameplate of the distribution box should be checked to ensure that it meets the actual usage conditions.

6.1.3 Check whether the compression sealing ring and gasket inside the introduction device of the distribution box are complete and intact.

6.1.4 Connect the distribution box to the grounding system of the site, and the grounding should be firm and reliable.

6.1.5 All fasteners must have anti loosening measures and will not loosen on their own.

6.1.6 When users connect wires, they only need to open the junction box, and the main chamber cover does not need to be opened.

6.2 Usage:

6.2.1 During use, it is strictly prohibited to open the lid with electricity.

6.3 Maintenance:

6.3.1 After installation or maintenance, attention should be paid to keeping the sealing ring at the inlet of the device tightly pressed to avoid affecting the explosion-proof performance of the product or causing water ingress inside the product and resulting in malfunction.

6.3.2 Regularly inspect the sealing ring of the introduction device, and replace it immediately if aging is found on the sealing ring.

6.3.3 Regularly inspect the explosion-proof surface and promptly apply anti rust oil to the explosion-proof surface. IIB explosion-proof distribution box model specification BXD53-8K explosion-proof power distribution box 380V price
