Analysis of dangerous points of high voltage circuit breaker test and control measures

Job Description: Measuring insulation resistance, measuring dielectric loss factor of less oil and multi-oil circuit breakers of 35kV and above, measuring leakage current, AC withstand voltage test danger point: personal electric shock

Control measures:

1.1 Measure the insulation resistance, change the wiring or discharge the equipment to the ground at the end of the test.

1.2 There must be reliable measures to prevent the wrong interval.

1.3 Insulation tools should be inspected before each use.

1.4 should work in the fence, no one is allowed to work on the equipment during the test.

1.5 When doing AC/DC withstand voltage test, the tester and the booster equipment should maintain a sufficient safety distance.

1.6 The metal casing of the test device shall be reliably grounded, and a bipolar knife gate with a significant breaking point shall be used.
