Description

Technical field [0001] The invention involves a grounded device, which is specifically for high -pressure contact network grounding device. Background technique [0002] When rectifying the electric locomotive, you need to disconnect the isolation switch of the contact network.Due to the high voltage of 25kV on the Internet of electrified railways, there is still residual electricity on the Internet after disconnection. In order to avoid damage to the operators and damage to the electrical equipment.Later, the operator's hand -connected ground rod was connected to the contact network, so as to achieve the purpose of grounding and exporting the residual conductivity of the contact online.The use of artificially connecting ground lines can achieve the purpose of preventing electromagnetic sensations and electrostatic induction. However, during the application of this method, operators need to work in dangerous areas. There is a large hidden safety hazard, which is not conducive to ...
