Visão geral de conformidade

Esta visão geral está disponível por enquanto apenas em inglês.

Escopo e aplicabilidade

This standard is applicable to high voltage laboratories (including high voltage test halls and outdoor test fields) and their working personnel. It also applies to on-site high voltage tests in substations and power plants where a test area is formed according to the standard's requirements. It is not intended for general low-voltage electrical testing.

Requisitos técnicos

This standard specifies comprehensive safety requirements for high voltage testing environments. It mandates that all technical content is mandatory. Compliance with grounding system integrity is strictly required, with grounding resistance generally not exceeding 0.5Ω and inspections every 5 years. The standard defines critical safety clearances based on test voltage levels for AC, DC, and impulse tests, referencing GB/T 16927.1 for proximity effect considerations. It also details personnel qualifications, requiring testers to have specific high voltage knowledge and pass annual exams. Furthermore, it outlines safety management measures, including the establishment of safety protocols, equipment operation procedures, and the requirement for a minimum of two personnel during testing, with a designated test leader.

Métodos de ensaio

This standard outlines specific safety procedures and testing protocols rather than traditional product testing methods. Key procedures include verifying the integrity of the grounding system (requiring resistance checks every 5 years), ensuring proper clearance distances during voltage application, and executing strict discharge procedures using grounding sticks before personnel can approach equipment. It also mandates safety checks for lifting operations and working at heights.

Perguntas frequentes

What products and facilities are regulated under GB 26861-2011?

GB 26861-2011 applies to high voltage laboratories (including indoor test halls and outdoor test fields) and their personnel. It also covers on-site high voltage tests in substations and power plants where a test area is formed according to the standard's requirements.

Are there specific clearance distance requirements in GB 26861-2011?

Yes, the standard defines strict safety clearances based on test voltage levels for AC, DC, and impulse tests. For example, it specifies minimum distances for voltages ranging from 200kV up to 4000kV, with adjustments required for altitudes above 1000m.

What are the personnel requirements for conducting high voltage tests under this standard?

Personnel must possess specialized high voltage knowledge, pass annual exams on the standard, and be trained in emergency aid. A minimum of two people is required for any test, with a designated test leader who acts as the safety responsible person.
