Vacuum switch and cable connection electricity testing device

Abstract

The invention discloses a vacuum switch and cable connection electricity testing device, which is characterized by comprising three 10kV overhead insulated wires, an electricity testing grounding ring, a cross arm, a porcelain bottle, three 10kV overhead insulated conductors and a vacuum switch. The 10kV overhead insulated wires are connected with the electricity testing grounding ring, and respectively comprise a silicon rubber insulating sheath; the electricity testing grounding ring comprises an exposed electricity testing grounding point; lower ends of the three 10kV overhead insulated wires respectively comprise a three-phase 10kV cable connecting terminal, upper heads of the three 10kV overhead insulated wires are respectively connected with the three overhead insulated conductors, and the three overhead insulated conductors are respectively covered by a plastic sheath; the middle positions of the three 10Kv overhead insulated conductors are fixed on the porcelain bottle, the porcelain bottle is mounted on the cross arm, and the upper heads of the three 10kV overhead insulated conductors are respectively connected with a lead-out board of the vacuum switch. With the device, the three 10kV overhead insulated conductors are connected with the lead-out board of the vacuum switch well, and the three 10kV overhead insulated wires are connected with the electricity testing grounding ring, so that the problem of hanging an earthing conductor is solved.

Description

technical field [0001] The invention relates to a vacuum switch and a cable connection electric testing device, which is mainly used for 10KV cable electric testing and hanging grounding wire. Background technique [0002] There are already 10KV three-core cables directly connected to the vacuum switch. Because the three-core cables are thick and hard, there is no way to connect the grounding ring for electrical testing, so there are disadvantages: first, it is impossible to hang the grounding wire for electrical testing; The switch is a hard connection, which can easily cause poor contact and cause accidents; the third is that if the cable is to be disconnected, the upper-level main line must be stopped, causing economic losses, loss of social benefits and failure to achieve power supply reliability. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, to provide a soft connection between a 10KV cable an...

[0002] There are already 10KV three-core cables directly connected to the vacuum switch. Because the three-core cables are thick and hard, there is no way to connect the grounding ring for electrical testing, so there are disadvantages: first, it is impossible to hang the grounding wire for electrical testing; The switch is hard-connected, which is likely to cause poor contact and cause accidents; third, if you want to disconnect the cable, you must stop the main line at the next level, resulting in economic losses, loss of social benefits and failure to achieve power supply reliability.
