Capacitor discharging tool

Abstract

The invention discloses a capacitor discharging tool, which comprises an insulated operation bar, a metal grounding bar, an elastic connector, a connection wire and a grounding wire, wherein the insulated operation bar is connected with the metal grounding bar through the elastic connector; two ends of the elastic connector are fixedly connected with the top end of the insulated operation bar and the bottom end of the metal grounding bar respectively; the top end of the connection wire is fixedly arranged at the bottom end of the metal grounding bar; the bottom end of the connection wire and the top end of the grounding wire are fixedly arranged on the insulated operation bar; the bottom end of the connection wire is fixedly connected with the top end of the grounding wire; the bottom end of the grounding wire is provided with a grounding end wire clamp for grounding; the top end of the metal grounding bar is provided with a linear extending sharp part and a bent extending hook part; and one end of the sharp part is fixedly connected with one end of the hook part. The traditional discharging mode is broken, the spring device is additionally arranged between the discharging metal part and the insulation rod, and through the bent angle and the recoverability of the spring, the discharging operation direction is changed, and the operation is more humanized.

Description

technical field [0001] The invention relates to a capacitor discharge tool, which belongs to the technical field of capacitor discharge. Background technique [0002] The capacitor bank works in a power failure. Although the discharge PT and the grounding knife can release most of the charge, there will still be residual charge on the capacitor at that time, especially after the fuse of the capacitor is broken, a large amount of charge will remain on the capacitor. If you do not discharge , Electric shock will occur; electric power safety regulations stipulate that before entering the capacitor bank to work, the capacitors must be discharged several times one by one. [0003] At present, there is no special discharge tool at the work site. Generally, the ground wire of the substation is used for discharge, and additional procedures for borrowing and returning the ground wire need to be performed; capacitor banks in the substation are generally arranged on 2 to 3 floors (see ...

AI Technical Summary

Problems solved by technology

For capacitors, in addition to single-stage discharge to ground, two-stage phase-to-phase discharge is also required (see Figure 4 Shown is the structure schematic diagram of the existing single capacitor), the early discharge tools can not meet the discharge requirements
