Generally, the disconnection switch further includes an earthing switch integrally assembled therewith to earth the disconnection switch when necessary, thereby ensuring safety of related equipment and maintenance personnel.
The existing grounding device used for the power distribution network has the following defects: 1. the wiring on the grounding device needs to be pressed, and the problem of inconvenient wiring exists when the grounding device is connected on a power distribution network; 2. the national grid company stipulates the evaluation requirement of an external insulation structure on the dry arc distance, and needs to reach a certain dry arc distance to the ground to ensure the safe operation of equipment with a lightning arrester, while the existing grounding device has the situation of insufficient dry arc distance to the ground; 3. the mechanical strength of the base of the grounding device is insufficient, and the normal operation of the grounding device can be influenced after the grounding device is used for a long time.
Disclosure of Invention
In view of this, the utility model aims at providing a high reliable earthing device that can wire fast satisfies the requirement of national grid earthing device to ground trunk arc distance, and has stronger mechanical strength, delays its life.
In order to realize above purpose, the utility model discloses a such high reliable earthing device that can work a telephone switchboard fast, include base channel-section steel and connect the post insulator on the base channel-section steel, be connected with back contact and back contact bent plate on the base channel-section steel, the last preceding contact backup pad that is provided with of post insulator, the one end of preceding contact backup pad is connected on the post insulator, and the other end bending type of preceding contact backup pad becomes the connecting portion that is higher than post insulator, be connected with preceding contact on the connecting portion, be connected with the ground connection switch between preceding contact and the back contact, still be connected with the line ball on the connecting portion.
The connecting part of the front contact supporting plate on the grounding device is higher than the post insulator, so that the dry arc distance of the front contact on the connecting part to the ground is increased, the requirement of a national power grid on the dry arc distance of the grounding device to the ground is met, and the working safety of the grounding device is improved; and be provided with the line ball spare on connecting portion, can realize quick wiring to improve earthing device's installation effectiveness.
This practicality further sets up to fix in connecting portion for the one end of line ball spare, and the other end of line ball spare forms the line ball hole, swing joint has the line ball screw on the line ball hole.
This practicality further sets up to the line ball and lies in post insulator directly over.
The wire is inserted into the wire pressing hole, the wire pressing screw is operated to fix the wire, the wire is not required to be bent and pressed to be operated under the screw, and actual wiring operation is facilitated.
The utility model discloses the both sides that set up to the base channel-section steel all form the hem, the transversal style of calligraphy of personally submitting "nearly" of base channel-section steel.
This practicality further sets up to preceding contact backup pad and is the Z type.
The U-shaped base channel steel has higher mechanical strength, is more stable when being installed in a power distribution network, and has longer service life; the Z-shaped front contact supporting plate can prolong the dry arc distance of the front contact to the ground, and is beneficial to actual processing.
