Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The utility model provides a take earth connection device of isolation switch, its theory of operation realizes protecting earth connection through the box body, avoids taking place the contact with the human body, utilizes the pivot and satisfies the not ground connection demand of co-altitude around the epaxial earth connection of commentaries on classics, reaches the purpose of ensureing earth connection and ground contact, avoiding the human probability of touching the earth connection and reducing the occurence of failure. The present invention will be described in further detail with reference to examples and embodiments.

As shown in fig. 1 and 2, a grounding wire device with isolation disconnecting link includes a fixed hoop 1 fixed on the utility pole (two ends of the hoop are provided with a plurality of mounting holes, and the inner diameter of the hoop is adjusted by selecting proper mounting holes and locking screws) and a junction box 2 arranged on the fixed hoop;
