Description
Technical field
The present invention relates to a kind of earth connection protective device, be specifically related to a kind of Repair of Transformer earth connection protective device.
Background technology
Workman needs the primary connection removing transformer when there being earth connection to protect; the inlet wire of existing transformer mostly adopts the mode of connection of power cable inlet wire; earth connection is arranged on cable; when removing the cable of transformer; transformer loses earth connection protection, thus threatens the personal safety of staff.
Summary of the invention
The present invention is for solving current workman when overhauling transformer; earth connection protective device is easily from landing nut; make transformer lose earth connection protection, thus threaten the problem of the personal safety of staff, and then propose a kind of Repair of Transformer earth connection protective device.
The present invention is the technical scheme taked that solves the problem: a kind of Repair of Transformer earth connection protective device of the present invention comprises spring, nut and two and half folders; the cross section of nut is dolioform; two and half mounting boards are contained on the lateral wall of nut; two and half press from both sides the setting that is in the shape of the letter V; and the lower end of two and half folders is hinged; the medial surface of each half folder upper end is provided with the arcwall face matched with nut lateral wall, and the middle part of two and half folders is connected by spring.
The invention has the beneficial effects as follows: present invention employs cross section be two and half of dolioform nut and earth connection press from both sides with the use of; earth connection protective device is not easy landing; make transformer be in ground protection state all the time, effectively can protect the personal safety of staff.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention, and Fig. 2 is nut structure schematic diagram of the present invention, and Fig. 3 is two and half clamping structure schematic diagrames of the present invention.
