Explosion proof electrical testing-Jiangsu Guobin Testing Technology Co., LTD

Explosion proof electrical testing testing items

Explosion proof electrical safety testing is a comprehensive inspection and testing of explosive gas and vapor hazardous areas, as well as explosion-proof electrical boxes, explosion-proof motors, explosion-proof lamps and other explosion-proof equipment used in explosive and hazardous areas, and the environment in which they are used. In accordance with the requirements of national AQ3009-2007 "Electrical Safety and Explosion Prevention Specification for Hazardous Areas" and "Construction Acceptance Specification for Electrical Equipment Installation Engineering Explosion and Fire Hazardous Environment Electrical Equipment", it identifies and searches for explosion-proof safety hazards in the environment or equipment, and provides professional on-site explosion-proof safety solutions. Provide a legally binding testing report.

Electrical circuit inspection in hazardous areas

General regulations:
1. Line laying method and wire diameter requirements;
2. Protection against potential mechanical damage, vibration, corrosion, and heat exposure;
3. Rated voltage requirements for cables and wires;
4. Selection of connection components such as junction boxes, distribution boxes, flexible joints, and isolation seals;
5. Requirements for the connection method of wires and cables.

Electrical circuit inspection in hazardous areas

Requirements for cable lines:

Grounding

Protective grounding:
1、 All non electrified exposed metals in explosive hazardous environments should be grounded or zeroed
2、 All electrical equipment in explosive hazardous environments must be specifically grounded
3、 The connection between the grounding main line (network) and the grounding body
4、 Protection and sealing requirements for grounding main lines crossing different environmental areas
5、 The dedicated grounding should be separately connected to the grounding main line (network), and the working neutral line should not be used as a protective grounding wire
6、 Requirements for the diameter of the dedicated grounding wire
7、 Grounding connection when installing cables into electrical equipment
8、 Install anti loosening bolts and other requirements.
