Description
Technical Field
The utility model relates to a power maintenance equipment is a drop out fuse earthing device for oil field 10KV oil well distribution device's change and maintenance.
Background
In a 10KV oil well distribution device, a transformer steps down a 10KV voltage to a 380V or 660V voltage, the transformer is usually a drop-out fuse (link) used as a power control element of the transformer, when the transformer is replaced, maintained and the like, a lower pile head of the fuse and related wiring thereof need to be touched, in order to ensure safety, the fuse is pulled out, a fusion tube is taken down, and then the lower pile head of the fuse is grounded. Because no special grounding device for the lower pile head of the drop-out fuse exists at present, the work of hanging and connecting the grounding wire by the lower pile head of the fuse is difficult to implement, so that potential safety hazards exist in related work of replacing a down lead, a transformer and the like.
Disclosure of Invention
The utility model aims at designing a drop out fuse earthing device, overcome the problem that the drop out fuse on the present oil well transformer does not have earthing device and has the potential safety hazard, make it can change safely, maintain the transformer.
The purpose of the utility model is realized like this: the drop-out fuse is provided with an upper pile head and a lower pile head, the lower part of the lower pile head is provided with two parallel hooks, the upper end of a connecting column is provided with a hook, the hook consists of a left retaining column, a cross rod, a right retaining column and a hook body, the right end of the left retaining column in a bent shape is connected with the left end of the cross rod into a whole, the left end of the right retaining column in a bent shape is connected with the right end of the cross rod into a whole, the upper part of the hook body is connected with the lower side of the middle part of the cross rod into a whole, so that the hook is provided with two hanging grooves with open lower ends, the two hanging grooves are matched with the two parallel hooks at the lower part of the lower pile head, the upper end of a grounding wire is provided with a wiring terminal, a bolt passes through the connecting column and is fastened on the connecting column, the lower end of the connecting column is provided with an insulating insertion hole, the left hanging groove in the two hanging grooves on the hook is hung in the left hook at, the grounding electrode is inserted into the ground plane, the lower end of the grounding wire is connected to the upper end of the grounding electrode, and the hook and the connecting column are made of copper.
The utility model has the advantages that: the insulating rod can be used for supporting the connecting column to enable the hook to be hooked in the hook on the lower pile head, the hook is provided with two hanging grooves with open lower ends and is matched with two parallel hooks on the lower portion of the lower pile head, the hook can be well contacted with the two parallel hooks on the lower portion of the lower pile head, the drop-out fuse is enabled to have ground protection, electric shock injury accidents of operators can not occur, the transformer can be safely replaced and maintained, and the insulating rod has remarkable economic and social benefits.
