방폭 전기 설치 전 검사

1. Explosion-Proof Markings

Explosion-proof designations, ~와 같은 “Exd II CT6,” 장비의 외부 케이스에 명확하게 표시되거나 주조되어야 합니다..

2. Product Nameplate

• Explosion-proof markings;

• 방폭인증번호;

• 생산 라이센스 기호;

• 특정 요구사항;

• 제조일자/일련번호.

3. Overall Appearance

• Explosion-proof metal enclosures: Ensure wall thickness and surface finish (casting and argon welding) are smooth and free from irregularities to meet explosion strength standards and porosity requirements.

• Larger products should maintain effective heat dissipation and meet temperature classification needs to extend service life.

• Equipment should feature both internal and external grounding with clear grounding indications.

• Check the configuration of electrical entry devices to support necessary construction wiring.

4. Structural Rationality

Components such as decoder boxes and power supply units should accommodate a specific number of circuits and the maximum allowable current and power.
