GB 26860 Electrical Safety Work Regulations (Electrical Part of Power Plants and Substations) GB 26161 Electrical Safety Work Regulations (Part 1: Thermal and Mechanical) DL/T 50091 Electrical Construction Safety Work Regulations (Part of Thermal Power Plants) DL/T 596 Preventive Test Procedures for Electrical Equipment. Electrical safety equipment refers to essential tools and tools used to protect the safe operation of electrical work and personal safety、 They can prevent accidents such as electric shock、 arc burns、 and high-altitude falls

Standard configuration tools for high-voltage distribution rooms

1. Insulation rubber pads 2. Switch operating handle 3. Indoor temperature and humidity meter 4. Insulating gloves and boots 5. Replace the fuse handle 6. Safety signs 7. Grounding wire group 8. Insulated operating rod 9. Safety signs 10. High voltage electroscope

Inspection indicators:

Insulation resistance test is to output a fixed DC voltage value、 and then detect the leakage current to ground or other parts. After applying pressure for 1 minute、 the obtained degree is the insulation resistance value. In the insulation resistance test、 the absorption ratio test is the core part、 which can timely reflect the degree of insulation damage and moisture return issues in electrical equipment. Only when the insulation resistance of the equipment at room temperature is qualified and the absorption ratio is within 1.3 can the insulation of the equipment be qualified

Power cable insulation faults and detection methods

The main reasons for cable faults are as follows:

(1) Mechanical damage (2) Damping of insulation (3) Insulation aging and deterioration (4) Overvoltage (5) Poor manufacturing process

Types and detection methods of cable insulation faults

There are three main types of cable insulation faults: firstly、 the damaged sheath causes local overheating、 accelerating insulation aging; Secondly、 insulation damage is caused by water intrusion、 which increases the incidence of water tree aging; Three types of corrosion produce partial discharge、 and electrical branches appear There are many fault detection methods for power cables、 mainly divided into offline detection methods and online detection methods

Offline detection technology for power cable insulation

(1) Dielectric loss factor test.
