A distribution network fault indicator

Abstract

The invention discloses a distribution network fault indicator, which comprises a housing of the fault indicator, and a clamping device for a high-voltage wire is arranged on the housing; the clamping device includes a An adjustment assembly, an engagement assembly corresponding to the adjustment assembly is provided on the other side of the housing opposite to the adjustment assembly, a suspension assembly is connected between the adjustment assembly and the engagement assembly, and the suspension assembly A clamping gap for high-voltage wires is provided between the component and the housing, and the high-voltage wires are clamped and fixed by the adjustment assembly, the connecting assembly and the suspension assembly arranged between the adjustment assembly and the connecting assembly on the housing. The locking structure compresses and fixes the high-voltage wires through the suspension components instead of the clamping action realized by the elastic deformation of the spring, which improves the installation stability of the fault indicator.

Description

technical field [0001] The invention relates to the technical field of distribution network line fault monitoring, in particular to a distribution network fault indicator. Background technique [0002] Fault indicators originated in Germany in the 1980s. They refer to intelligent devices installed on power lines for online detection, indicating circuit and single-phase ground faults, and helping people find fault points. It can be applied to power equipment such as ring network cabinets, switching stations and switch cabinets of power distribution rooms for overhead lines and cable lines. The fault indicator uses the principle of electromagnetic induction. When the line fails, it will pass the fault current. When the fault current reaches the tower where the indicator is installed, the fault indicator will induce the fault current through the internal electromagnetic coil to generate a mechanical transmission flip sign. In this way, the indication of the faulty section is r...

Problems solved by technology

[0006] To this end, the present invention provides a distribution network fault indicator, which clamps and fixes the high-voltage wires through the adjustment assembly, the connection assembly and the suspension assembly arranged between the adjustment assembly and the connection assembly on the housing, and adopts mechanical locking The structure presses and fixes the high-voltage wires through the suspension components instead of the clamping action realized by the elastic deformation of the springs, so as to solve the problem that the fault indicator cannot be compatible with the high-voltage wires in the prior art because the clamping force of the springs gradually decreases with time. The problem of slipping and falling off due to the wire being pressed and fixed
