Control cable insulation test auxiliary box

The utility model relates to a control cable insulation test auxiliary box, and belongs to the control cable insulation test equipment field; the technical scheme is that a 500V tramegger L-pole wiring end (20) is arranged between a 500V tramegger L-pole and a test operation zone (18), and the three are mutally connected; a 500V tramegger E-pole wiring end (21) is arranged between a 500V tramegger E-pole and an insulation troubleshooting zone (19), and the three are mutally connected; a ground terminal (22) is connected with the ground; a ground end single-control switch is arranged between the 500V tramegger E-pole wiring end and the ground terminal; a to-be-tested control cable wire core wiring zone, the test operation zone and the insulation troubleshooting zone are connected in sequence; to-be tested wire cores are matched one by one in positions with a pluggable spring terminal, a dual-control switch and a single-control switch. The auxiliary box is matched with the 500V digit tramegger, so whole testing project can be operated by one person, thus reducing work load, improving work efficiency, and removing electric shock hidden troubles in insulation remote tests of the control cable wire cores.
