Problems solved by technology

There are the following deficiencies: one is the potential safety hazard of loose connection; the other is that the anti-corrosion paint on the grounded flat iron needs to be removed during installation, and the anti-corrosion paint on the grounded flat iron must be restored after the connection is completed; the third is that the grounded flat iron is tight Attached to the base of the capacitor tower, the space for mounting the ground wire is very small, and the installation time is long

Embodiment Construction

[0008] Such as figure 1 As shown, a special grounding device for high-voltage shunt capacitors in substations is mainly composed of a grounding pile base 1 and a grounding pile body 2 welded thereon. Wing nuts 3 and ground wire joint bolts 5 are installed on the outside respectively.

[0009] When in use, since the grounding pile base and the grounding flat iron are welded, only the grounding wire 6 needs to be inserted into the grounding pile body 2 through the grounding wire joint bolt 5, fixed by the transition nut 4, and then tightened by the wing nut 3. It can be fixed. When removing the grounding wire 6, first remove the wing nut 3, then remove the transition nut 4, and then pull the grounding wire 6 out of the grounding pile body 2 through the grounding wire joint bolt 5.

Abstract

The invention discloses a matching device used during maintenance of high-voltage parallel capacitors in substations, in particular to a special grounding device for high-voltage parallel capacitors in substations. It is mainly composed of the ground pile base and the ground pile body arranged on it. Its structural characteristics are that transition nuts are symmetrically arranged on both sides of the ground pile body, and wing nuts and ground wire joint bolts are respectively arranged outside the transition nuts. The invention has the advantages of safe use and high work efficiency.

Description

technical field [0001] The invention relates to a matching device used during maintenance of high-voltage shunt capacitors in substations, in particular to a special grounding device for high-voltage shunt capacitors in substations. Background technique [0002] When the high-voltage shunt capacitor in the substation is damaged and needs to be replaced, in order to prevent the accidental power transmission during the maintenance process or the reverse power transmission of other equipment connected to the capacitor to the capacitor and endanger the safety of the on-site staff, it is necessary to install a grounding device on the low-voltage side of the capacitor bank. Wire. Since the capacitor does not have a dedicated grounding wire device, the grounding wire can only be connected to the grounding flat iron through winding or additional clamps. There are the following deficiencies: one is the potential safety hazard of loose connection; the other is that the anti-corrosion...
