| Abstract: | The high-voltage cable of shovel easy occures the short circuit breakdown caused bygroundconnection,thus causing equipment failure or personal casualty accident.In order to take prpventive meaures,the insulation monitor or the electric-magnetic current leakage protection device can beused to protect the cable.The above-mentioned two devices are presented in detail,at the same time,themethods of seeking cable breakdown by using the flaw detector of cable or the direct-current potentionmeter are presented. |
