1 Scope

This part of DZ/T 0276 specifies test methods for determining rock breakdown voltage and breakdown strength. This section applies to rock breakdown voltage and breakdown strength test in rock physical and mechanical properties test.

2 Terms and definitions

The following terms and definitions apply to this document. 2.1 Breakdown voltage breakdownvoltage When a commercial power supply frequency voltage is applied to a rock sample by a continuous boosting method, the voltage value at which the rock sample is broken down is kV. Said. 2.2 Breakdown strength breakdownstrength The ratio of the voltage at which the rock sample is broken down to its thickness is expressed in kV/mm.

3 Principle

Applying an industrial power supply frequency voltage to the rock sample by continuous boosting until the sample is broken down, reading the breakdown voltage value, and then The breakdown strength was calculated by dividing the thickness of the sample.

4 instruments

4.1 High voltage breakdown test device (as shown in Figure 1).
