Electric power circuit fault indicator

Abstract

The invention discloses an electric power circuit fault indicator which comprises an outer shell, a wire clamping part arranged on the upper portion of the outer shell, a control circuit part with a detecting and judging function, and an indication part with a fault indicating function. The outer shell comprises a left upright column and a right upright column, and the upper portion of a shell body is in a U shape. The wire clamping part comprises a spring and wire pressing plates in a J shape. The wire pressing plates are respectively connected with mounting holes of the left upright column and the right upright column of the outer shell, can rotate relative to the left upright column and the right upright column, and respectively clamp electric power wires in V-shaped grooves of the left upright column and the right upright column from the left side and the right side. The spring is used for connecting the wire pressing plates and bolts on the upright columns. When clamping wires are mounted, the spring is in a drawing state, the spring contracts after the wire pressing plates are triggered, and the wire pressing plates tightly press the electric power wires. The electric power circuit fault indicator can solve the problems that installation and disassembly are inconvenient, fault indication is not obvious, a malfunction rate is high, and a wire clamping device of an electric power circuit is easy to damage and rust and the like in the prior art.

Description

technical field [0001] The invention relates to a power line fault indicator. Background technique [0002] The power line fault indicator is a fault information indicating device used to detect and indicate whether the fault circuit of the user's power line flows through it. Its working principle is that when the power line fails, due to the sudden change of electrical parameters in the line, changes in the magnetic field and electric field around the power line are generated. The control circuit inside the power line fault indicator monitors these variables and automatically judges whether the fault circuit flows through Here, an alarm signal is further output to drive the display part to work, and an alarm flashes a red indicator light, so as to achieve the purpose of indicating the failure of the faulty line. Although the existing various power line fault indicators can detect line faults, they still have the following disadvantages: [0003] 1. It is inconvenient to i...
